Use sigma notation to represent the sum of the first eight terms of the following sequence: 4,7. 10,

Answers

To answer this question, we need to check the kind of sequence here. We have that the first three elements of the sequence are:

[tex]4,7,10[/tex]

If we have the difference between the second element and the first element, and the difference between the third element and the second element, we have:

[tex]7-4=3,10-7=3[/tex]

Thus, we have a common difference of 3. This is an arithmetic sequence. Then, we also have that:

[tex]a_n=a_1+(n-1)d[/tex]

This is the formula for finding a general term in an arithmetic sequence, where:

• an is any term, n, in the sequence.

,

• a1 is the first term in the sequence.

,

• n the number of the term in the sequence.

,

• d is the common difference of the sequence.

In this way, we have:

a1 = 4

d = 3

Answers

Answer:

[tex]1-\frac{1}{2}=\frac{1}{2}[/tex]

Explanation:

Given the below expression;

[tex]\frac{7}{8}-\frac{6}{11}[/tex]

We can see that 7/8 is closer to 1 and that 6/11 is closer to 1/2, so we'll now have;

[tex]1-\frac{1}{2}=\frac{2-1}{2}=\frac{1}{2}[/tex]

So the best estimation of the equation is 1 - 1/2 = 1/2

Charlie is saving money to buy a game. So far he has saved $16, which is one-half of the total cost of the game. How much does the game cost?

Answers

Answer:

If $16 is just one-half of the total cost of the game, then the cost of the game must be $32.

Explanation:

See the illustration below for 1/2.

Charlie has saved $16 already which is 1/2 of the total game cost.

As we can see above, Charlie needs 1/2 more to be able to buy a game. This means Charlie needs to save an additional $16.

In total, Charlie must saved $16 + $16 = $32 to buy the game.

The game cost must be $32.

For how many books produced will the costs from the two methods be the same

Answers

Answer:

[tex]4780\text{ books}[/tex]

Explanation:

Here, we want to get the number of books for which the cost of the two methods will be the same

What we have to do here is to get the cost of each method, then equate to find the number of books

Let the number of books be b

For the first method, we have it that:

[tex]\begin{gathered} 70976\text{ + }9.75(b) \\ =\text{ 70976 + 9.75b} \end{gathered}[/tex]

For the second method, we have it that:

[tex]\begin{gathered} 16006\text{ + }21.25(b) \\ =\text{ 16006 + 21.25b} \end{gathered}[/tex]

To get the number of books, we have to equate both

Mathematically, that would be:

[tex]\begin{gathered} 70976\text{ + 9.75b = 16006 + 21.25b} \\ 70976-16006\text{ = 21.25b-9.75b} \\ 54970\text{ = 11.5b} \\ b\text{ = }\frac{54970}{11.5} \\ b\text{ = 4,780} \end{gathered}[/tex]

Deion measure the volume of a sink basin by modeling it as a hemisphere. Deion measures its diameter to be 28 3/4 inches. Find the sink’s volume in cubic inches. Round your answer to the nearest tenth if necessary.

Answers

28.75We are asked to determine the volume of a hemisphere of diameter 28 3/4 in.

A hemisphere is half a sphere therefore, its volume is half the volume of a sphere:

[tex]V=\frac{1}{2}(\frac{4\pi r^3}{3})=\frac{2\pi r^3}{3}[/tex]

Where "r" is the radius. Since the radius is half the diameter we have that:

[tex]r=\frac{D}{2}=\frac{28\frac{3}{4}}{2}[/tex]

We will convert the mixed fraction into a standard fraction using the following:

[tex]28\frac{3}{4}=28+\frac{3}{4}=28.75[/tex]

Substituting in the formula for the radius:

[tex]r=\frac{28.75in}{2}=14.38in[/tex]

Now, we substitute the value of the radius in the formula for the volume:

[tex]V=\frac{2\pi(14.38in)^3}{3}[/tex]

Solving the operations:

[tex]V=6221.3in^3[/tex]

Therefore, the volume is 6221.3 cubic inches.

This is because the hexagon is divided into one rectangle and 2 congruent triangles. Therefore, the area of the two triangles will be the same since they are congruent triangles. In order to get the area of the hexagon, the area of one of the triangles is mutiplied by 2 and added to the area of the rectangle.

Step 2

Find the dimension of one of the shaded triangle from Bev's pattern.

[tex]\begin{gathered} \text{Area of given triangle=6unit}^2 \\ \text{Area of Bev's triangle=}\frac{1}{2}\times4\times3=6unit^2 \end{gathered}[/tex]

The area of all shaded triangles in Bev's pattern are equal. This is because all the shaded triangles have the same dimensions and can be said to be congruent. Hence, they will have the same area.

It is required to state what the constant 0.98 reveal about the rate of change of the quantity by completing the given statement:

The function is exponentially at a rate of every .

Notice from the given exponential function that the factor is 0.98.

Since it is less than 1, it implies that it is an exponential DECAY.

Subtract the factor 0.98 from 1 to get the decay rate:

[tex]1-0.98=0.02=0.02\times100\%=2\%[/tex]

Unit of t: decades

The exponent is 10t.

The reciprocal is 1/10.

Hence, the time frame of rate is: 1/10 of a decade.

This is equivalent to a year.

The complete statement is, therefore:

The function is decaying exponentially at a rate of 2% every year.

Create a list of steps, in order, that will solve the following equation.5(x-3)² + 4 = 129Solution steps:

Answers

We want to solve the equation

[tex]5\cdot(x-3)^2+4=129[/tex]

To solve this equation, we must isolate the variable on one side of the equation. So, noticed that the term with the x has multiple things (it is raised to the second power, multiplied by five, etc) so we begin by subtracting 4 on both sides. (Step 1)

So we get

[tex]5\cdot(x-3)^2=129\text{ -4 =125}[/tex]

Now we divide both sides by 5 (Step 2), so we get

[tex](x-3)^2=\frac{125}{5}=25[/tex]

now we take the square root on both sides (Step 3). Then we get

[tex]\sqrt[]{(x-3)^2}=\sqrt[]{25}=5=x\text{ -3}[/tex]

Finally, we add 3 on both sides (Step 4). Then we get

Answers

The practical range of the function is D. all real numbers from 2.7 to 10.8, inclusive.

What is a range?

A function's range refers to all of the possible values for y. The formula for determining a function's range is y = f. (x). A function's range is the set of all its outputs. After we have substituted the domain, the range of a function is the complete set of all possible resulting values of the dependent variable (y, usually).

In this case, since the range is the value that satisfies the given function. For function f(t) = 2.7t the practical range of the function can be solved by substituting the lowest time and the highest possible time which are 1 and 4.

At t = 1 f(t) = 2.7 and at t = 4 f(t) = 10.8. so the range is all real numbers from 2.7 to 10.8, inclusive.

Therefore, the correct option is D.

The figure shows the layout of a symmetrical pool in a water park. What is the area of this pool rounded to the tens place? Use the value = 3.14.

Answers

EXPLANATION:

Given;

We are given a symmetrical pool as indicated in the attached picture.

The pool consists of two sectors and two triangles and each pair has the same dimensions.

The dimensions are as follows;

[tex]\begin{gathered} Sector: \\ Radius=30 \\ Central\text{ }angle=2.21\text{ }radians \end{gathered}[/tex][tex]\begin{gathered} Triangle: \\ Slant\text{ }height=30 \\ Vertical\text{ }height=25 \\ Base=20 \end{gathered}[/tex]

Required;

We are required to calculate the area of the pool.

Step-by-step solution;

We shall begin by calculating the area of the sector and the formula for the area of a sector is;

[tex]\begin{gathered} Area\text{ }of\text{ }a\text{ }sector: \\ Area=\frac{\theta}{2\pi}\times\pi r^2 \end{gathered}[/tex]

Where the variables are;

[tex]\begin{gathered} \theta=2.21\text{ }radians \\ r=30 \\ \pi=3.14 \end{gathered}[/tex]

We now substitute and we have the following;

[tex]Area=\frac{2.21}{2\pi}\times\pi\times30^2[/tex][tex]Area=\frac{2.21}{2}\times900[/tex][tex]Area=994.5ft^2[/tex]

Since there are two sectors of the same dimensions, the area of both sectors therefore would be;

[tex]Area\text{ }of\text{ }sectors=994.5\times2[/tex][tex]Area\text{ }of\text{ }sectors=1989ft^2[/tex]

Next we shall calculate the area of the triangles.

Note the formula for calculating the area of a triangle;

[tex]\begin{gathered} Area\text{ }of\text{ }a\text{ }triangle: \\ Area=\frac{1}{2}bh \end{gathered}[/tex]

Note the variables are;

[tex]\begin{gathered} b=20 \\ h=25 \end{gathered}[/tex]

The area therefore is;

[tex]Area=\frac{1}{2}\times20\times25[/tex][tex]Area=\frac{20\times25}{2}[/tex][tex]Area=250[/tex]

For two triangles the area would now be;

[tex]Area\text{ }of\text{ }triangles=250\times2[/tex][tex]Area\text{ }of\text{ }triangles\text{ }equals=500ft^2[/tex]

Therefore, the area of the pool would be;

A zero-coupon bond is a bond that is sold now at a discount and will pay its face value at the time when it matures; no interest payments are made.A zero-coupon bond can be redeemed in 20 years for $10,000.  How much should you be willing to pay for it now if you want the following returns?(a) 8% compounded daily(b) 8% compounded continuously

Answers

EXPLANATION:

We are given a zero-coupon bond that will be worth $10,000 if redeemed in 20 years time at an annual rate of 8% compounded;

(a) Daily

(b) Continuously

The formula for compounding annually is given as follows;

[tex]A=P(1+r)^t[/tex]

Here the variables are;

[tex]\begin{gathered} P=initial\text{ investment} \\ A=Amount\text{ after the period given} \\ r=rate\text{ of interest} \\ t=time\text{ period \lparen in years\rparen} \end{gathered}[/tex]

Note that this zero-coupon bond will yield an amount of $10,000 after 20 years at the rate of 8%. This means we already have;

[tex]\begin{gathered} A=10,000 \\ r=0.08 \\ t=20 \end{gathered}[/tex]

(a) For interest compounded daily, we would use the adjusted formula which is;

[tex]A=P(1+\frac{r}{365})^{t\times365}[/tex]

This assumes that there are 365 days in a year.

We now have;

[tex]10000=P(1+\frac{0.08}{365})^{20\times365}[/tex][tex]10000=P(1.00021917808)^{7300}[/tex][tex]10000=P(4.95216415047)[/tex]

Now we divide both sides by 4.95216415047;

[tex]P=\frac{10000}{4.95216415047}[/tex][tex]P=2019.31916959[/tex]

We can round this to 2 decimal places and we'll have;

[tex]P=2019.32[/tex]

(b) For interest compounded continuously, we would use the special formula which is;

[tex]A=Pe^{rt}[/tex]

Note that the variable e is a mathematical constant whose value is approximately;

[tex]e=2.7183\text{ \lparen to }4\text{ }decimal\text{ }places)[/tex][tex]10000=Pe^{0.08\times365}[/tex][tex]10000=Pe^{29.2}[/tex]

Can you help me please?A. How can Marc provide proof that his mighty shot actually hung in the air for 15 seconds? Or is this just another one of his lies?B. How long did the ball actually hang in the air?

Answers

The given formula for Marc's shot is:

[tex]h(x)=-16x^2+200x[/tex]

a. To prove that the shot actually hung in the air for 15 seconds, we need to replace x=15 in the formula and solve for h, as follows:

[tex]\begin{gathered} h(15)=-16(15)^2+200(15) \\ h(15)=-16\times225+3000 \\ h(15)=-3600+3000 \\ h(15)=-600 \end{gathered}[/tex]

As the height is negative, it means after 15 seconds the ball already hit the ground, because the ground is located at h=0. Then this result proves that this is just another one of Marc's lies.

b. To find how long the ball actually hung in the air, we need to find the x-values that makes h=0, as follows:

[tex]0=-16x^2+200x[/tex]

We have a polynomial in the form: ax^2+bx+c=0, where a=-16, b=200 and c=0.

We can use the quadratic formula to solve for x:

[tex]\begin{gathered} x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ x=\frac{-200\pm\sqrt[]{(200)^2-4(-16)(0)}}{2(-16)} \\ x=\frac{-200\pm\sqrt[]{40000+0}}{-32} \\ x=\frac{-200\pm\sqrt[]{40000}}{-32} \\ x=\frac{-200\pm200}{-32} \\ x=\frac{-200+200}{-32}=\frac{0}{-32}=0\text{ and }x=\frac{-200-200}{-32}=\frac{-400}{-32}=12.5 \end{gathered}[/tex]

Then the two x-values are x=0 and x=12.5.

The starting time is 0 and the end time when the ball hit the ground is x=12.5.

The ball actually hung in the air 12.5 seconds.

Hi! I just wanted to know may you please help me on knowing how to solve an inequality?

Answers

When given an inequality, we solve it as if we were solving an equation but there is one important consideration: If we divide or multiply by a negative number the inequality gets inverted.

Recall that to solve an equation we add, subtract, multiply, etc. to isolate the variable, in the case of inequalities we do the same process.

Example 1. x+58>36, to solve the inequality for x, we have to put the variable by itself on one side of the inequality, to do that we have to eliminate whatever is next to the variable, in the case 58 is adding, therefore, we must subtract it, but to not alter the inequality we do the same to both sides of the inequality.

Adding -58 to both sides of the inequality we get:

[tex]\begin{gathered} x+58-58>36-58, \\ x>-22. \end{gathered}[/tex]

Therefore, the solution to this inequality is x>-22.

Example 2. -3x+3<4:

Adding -3 to both sides of the inequality we get:

[tex]\begin{gathered} -3x+3-3<4-3, \\ -3x<1. \end{gathered}[/tex]

Dividing by -3 we get:

[tex]\begin{gathered} \frac{-3x}{-3}>\frac{1}{-3}, \\ x>-\frac{1}{3}\text{.} \end{gathered}[/tex]

Elaine drives her car 50 miles and has an average of a certain speed. If the average speed had been 4mph more, she could have traveled 58 miles in the same length of time. What was her average speed?

Answers

Hello there. To solve this question, we'll have to remember some properties about average speed.

When we're talking about moving in a straight line, the average speed is given by the ratio between the displacement ΔS and the interval of time Δt, namely

[tex]v=\frac{ΔS}{Δt}[/tex]

In this case, say we have an average speed of v and the initial displacement ΔS = 50 miles in a certain interval of time Δt, such that

[tex]v=\frac{50}{Δt}[/tex]

We know that if the average speed had been 4 mph more, then Elaine could have traveled 58 miles in the same length of time.

This means that v + 4 (that is, the average speed plus 4 mph) is equal to the ratio:

[tex]v+4=\frac{58}{Δt}[/tex]

To solve this for v, we can start assuming that the interval of time Δt is not equal to zero, so do the average speed in the second equation.

Divide the first equation by the second, such that

[tex]\begin{gathered} \frac{v}{v+4}=\frac{\frac{50}{Δt}}{\frac{58}{Δt}} \\ \\ \frac{v}{v+4}=\frac{50}{58} \end{gathered}[/tex]

Cross multiply the numbers, that is:

[tex]\begin{gathered} 58v=50\cdot(v+4) \\ 58v=50v+200 \end{gathered}[/tex]

Subtract 50v on both sides of the equation

[tex]8v=200[/tex]

Divide both sides by a factor of 8

[tex]v=25\text{ mph}[/tex]

So this is her average speed.

what type of angle is angle 98 degrees​

Answers

Answer:

Obtuse

Step-by-step explanation:

Since it is larger than 90 degrees but less than 180 degrees, an angle of 98 degrees is considered to be obtuse.

Hope this helps! :)
