A parabola has a vertex at (2, -1) and a y- intercept at (0,3). Is this enough information to sketch a graph? Explain your answer. Henny Yoffe . 11:20 AM

Answers

Answer 1

It is given that the parabola has the vertex at (2,-1)and y intercept of 3,

Consider the general equation of the parabola with vertex (p,q),

[tex]y=a(x-p)^2+q[/tex]

Sbstitute 2 for 'p' and -1 for 'q',

[tex]y=a(x-2)^2-1[/tex]

Given that the y-intercept is 3, it means that the curve passess through (0,3),

So it must satisfy the equation,

[tex]3=a(0-2)^2-1\Rightarrow4a=4\Rightarrow a=1[/tex]

Substitute the value of 'a', 'p', and 'q' in the standard equation,

[tex]y=1(x-2)^2-1\Rightarrow y=(x-2)^2-1[/tex]

Thus, the equation of the parabola can be obtained using the given conditions.

which of the triangles cannot be proved congruent? so a different tutor gave me the answer which is D. But he told me to ask another tutor to tell me how to type out how I got the answer.

Answers

The triangles that cannot be proved congruent are the triangles in option D. We are not told that the other side is congruent to the corresponding side of the other triangle.

To prove they are congruent, we need to know the other side is congruent and prove this using the SSS postulate.

In the other cases, we can be proved they are congruent by:

• Case A ---> SAS postulate.

,

• Case B ---> ASA postulate.

,

• Case C ---> SSS postulate (the triangles share a common side)

In summary, we only have that the triangles in D cannot be proved congruent since we have two corresponding congruent sides, and one angle (vertical angle) to be congruent corresponding parts. It would be an SSA method. However, this method is not Universal, and it is not enough to demonstrate they are congruent.

In one month, Jason eams $32.50 less than twice the amount Keyin earns, Jason earns $212.50write and solve an equation to solve for the amount of money that kevin earns

Answers

Let the amount Kevin earns be represented with K

Let the amount Jason earns be represented with J

Jason earns $32.50 less than twice Keyin earns can be represented by

J = K - 32.5 ----- equation 1

Jason earns $ 212.5

J = 212.5 ----- equation 2

From equation 1, we can write the equation to solve for what Kevin earns

J = K - 32.5

Making K the subject of the formula

K = J + 32.5

Putting J = 212.5 into the equation above

K= $ 212.5 + $ 32.5

K = $ 245

We will have the following:

***First:

[tex]h=h_0+v_0\cdot t+\frac{1}{2}g\cdot t^2[/tex]

Now, we will determine the value for the speed:

[tex]1840=1600+v_0\cdot(4)+\frac{1}{2}(-32.17)\cdot(4)^2\Rightarrow240=4v_0-\frac{25736}{25}[/tex][tex]\Rightarrow\frac{31736}{25}=4v_0\Rightarrow v_0=\frac{7934}{25}\Rightarrow v_0=137.36[/tex]

[tex]h=1600+317.36t+\frac{1}{2}gt^2[/tex]

Here "g" is the gravitational pull of earth.

***Second:

We will determine how much time it would take for the arrow to hit the ground as follows:

[tex]0=1600+317.36t+\frac{1}{2}(-32.17)t^2\Rightarrow-\frac{3217}{200}t^2+317.36t+1600=0[/tex][tex]\Rightarrow t=\frac{-(317.36)\pm\sqrt[]{(317.36)^2-4(-\frac{3217}{200})(1600)}}{2(-\frac{3217}{200})}\Rightarrow\begin{cases}t\approx-4.163 \\ t\approx23.893\end{cases}[/tex]

sum xi = 15

Replacing we have:

[tex]m=\frac{6\cdot12788-(15\cdot5346)}{6(55)-(15)^2}=\frac{-3462}{105}=-32.971[/tex]

m= -32.971

And the intercept would be:

[tex]b=\frac{\sum^n_{i=1}y_i}{n}-m\cdot\frac{\sum^n_{i=1}x_i}{n}=\frac{5346}{6}-(-32.971)\cdot\frac{15}{6}=973.429[/tex]

b= 973.428

Then the equation would be:

y= -32.971x+ 973.428

And we can find the value of x for y = 767 and we got::

767 = -32.971x+ 973.428

Solcing for x we have:

Find d and then find the 20th term the sequence. Type the value of d (just the number) in the first blank and then type the 20th term(just the number) in the second blank.a1=6 and a3=14

Answers

We have that an arithmetic sequence can be defined by the following explicit formula:

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

where n represents the index of each term in the sequence and d represents the common difference beteen each term. a1 is the first term of the sequence.

In this case we have that the first term is a1 = 6, and also we have that a3=14. We can use the formula to find the common difference:

[tex]\begin{gathered} a_3=a_1+(3-1)d \\ \Rightarrow a_3=a_1+2d \\ \Rightarrow14=6+2d \end{gathered}[/tex]

solving for d, we get:

[tex]\begin{gathered} 2d+6=14 \\ \Rightarrow2d=14-6=8 \\ \Rightarrow d=\frac{8}{2}=4 \\ d=4 \end{gathered}[/tex]

therefore, the value of d is d = 4.

We have now the explicit formula for the sequence:

[tex]\begin{gathered} a_n=6_{}+4(n-1) \\ \end{gathered}[/tex]

then, for the 20th term, we have to make n = 20 on the formula, and we get the following:/

[tex]\begin{gathered} a_{20}=6+4(20-1)=6+4(19)=6+76=82 \\ \Rightarrow a_{20}=82 \end{gathered}[/tex]

therefore, the 20th term is 82

The overall course average is the average weight of all the quizzes, tests, finals, labs.

First we need the average for all the information:

Quiz Average: 95 (given)

Lab Average: 89 (given)

Test Average >> we have to find by summing and dividing by number of tests

[tex]\text{average}=\frac{52+82+88}{3}=74[/tex]

Final Exam: 73 (1 exam, so this is the average).

Thus, the information we have:

Quiz Avg = 95

Lab Avg = 89

Test Avg = 74

Final Avg = 73

Now, we multiply the scores with the respective weightage(in decimal) and sum it. We get:

[tex]95\mleft(0.25\mright)+89\mleft(0.25\mright)+74\mleft(0.35\mright)+73\mleft(0.15\mright)=82.85[/tex]

The hypotenuse of a right triangle is 1 centimeter longer than the longer leg. The shorter leg is 7 centimeters shorter than the longer leg. Find the length of the shorter leg of the triangle.

Answers

Answer:

[tex]\text{Shorter leg= 5cm}[/tex]

Step-by-step explanation:

As a first step to go into this problem, we need to make a diagram:

Let x be the measure of the longer leg.

Now, understanding this we can apply the Pythagorean theorem to find x, it is represented by the following equation:

[tex]\begin{gathered} a^2+b^2=c^2 \\ \text{where,} \\ a=\text{longer leg} \\ b=\text{shorter leg} \\ c=\text{hypotenuse } \end{gathered}[/tex]

Substituting a,b, and c by the expressions corresponding to its sides:

[tex]\begin{gathered} x^2+(x-7)^2=(x-1)^2 \\ \end{gathered}[/tex]

apply square binomials to expand and gather like terms, we get:

[tex]\begin{gathered} x^2+x^2-14x+49=x^2-2x+1 \\ 2x^2-x^2-14x+2x+49-1=0 \\ x^2-12x+48=0 \end{gathered}[/tex]

Now, factor the quadratic equation into the form (x+?)(x+?):

[tex]\begin{gathered} (x-4)(x-12)=0 \\ x_1=4 \\ x_2=12 \end{gathered}[/tex]

This means, the longer leg could be 4 or 12, but if we subtract 7 to 4, we get a negative measure for the shorter leg, that makes no sense.

Therefore, the long leg is 12 cm.

Hence, if the shorter leg is 7 centimeters shorter than the longer leg:

[tex]\begin{gathered} \text{Shorter leg=12-7} \\ \text{Shorter leg=}5\text{ cm} \end{gathered}[/tex]

write an equation to represent"three consecutive integers is 12 less than 4 times the middle integer'

Answers

Consider that the three consecutive integers are:

least integer = n

middle integer = n + 1

greatest integer = n + 2

THe expression "three consecutive integers is 12 less than 4 times the middle integer" can be written as follow:

n + (n + 1) + (n + 2) = 4(n +1) - 12

In order to find the numbers, proceed as follow:

n + (n + 1) + (n + 2) = 4(n +1) - 12 cancel parenthesis

n + n + 1 + n + 2 = 4n + 4 - 12 simplify like terms

3n + 3 = 4n - 8 subtract 4n and 3 both sides

3n - 4n = - 8 - 3

-n = -11

n = 11

Hence, the three consecutive integers are:

n = 11

n + 1 = 12

n + 2 = 13

This means 80% of the fish in a tank have fin rot.

Now, for one tank 80% of 40 fish is

[tex]\frac{80\%}{100\%}\times40=32[/tex]

Now, since there are 5 fish tanks in the store and 32 fish in each have fin rot; therefore, the total number of fish that have fin rot will be

Hence, the estimated number of fish with fish rot in the store is 160.

Solve the system by the addition method x + 2y = - 26x + 3y = - 30

Answers

We are asked to solve the following system of equations via the addition method:

x + 2 y = - 2

6 x + 3 y = - 30

so via the addition method we will try to eliminate one of the variables by multiplying for the appropriate factor that would ease tha process. We notice that if wemultiply the whole first eqaution by the factor (-6), we will be able to in the second step eliminate the term in "x" by combining both equations term by term.

So we do that: Multiply the whole first equation by "-6":

(-6) (x + 2 y ) = (-6) (-2)

- 6 x - 12 y = 12

now we combine this with the second equation term by term to eliminate the term in x:

- 6 x - 12 y = 12

+

6 x + 3 y = - 30

_______________

0 - 9 y = - 18

Now divide both sides by "-9" to isolate y:

y = - 18 / (-9)

y = 2

Now we use y = 2 in the very first equation to solve for the variable x:

x + 2 y = - 2

x + 2 (2) = -2

x + 4 = - 2

subtract 4 from both sides:

x = - 2 - 4

x = - 6

STEP BY STEP EXPLANATION:

To know if the ordered triple is a solution of the system, we need to that (4, 4, 4) means x = 4, y = 4 and z = 4.

Then, to know if it is a solution we must replace the values on each equation to verify if the values are solutions

We have three equations:

1. x - 5y = -16

Replacing x = 4 and z = 4, we obtain

[tex]\begin{gathered} 4\cdot4-6\cdot4=-8 \\ 16-24=-8 \\ -8=-8 \\ \text{ TRUE} \end{gathered}[/tex]

The ratios y/x are:

[tex]\frac{y}{x}=-\frac{5}{2},-\frac{11}{4},-\frac{17}{6},-\frac{23}{8}[/tex]

So, x and y show:

Note that xy is not constant, for their product differs. So it is not an

inverse variation.

On the other hand, y/x is not constant as well. So it is not a direct variation.

Find y if the point (5,y) is on the terminal side of theta and cos theta = 5/13

Answers

For this problem we have a point given (5,y) and we know that this point is on a terminal side of an angle, we also know that:

[tex]\cos \theta=\frac{5}{13}[/tex]

If we know the cos then we can find the sin on this way:

[tex]\sin \theta=\frac{y}{13}[/tex]

Then we can apply the following identity from trigonometry:

[tex]\sin ^2\theta+\cos ^2\theta=1[/tex]

Using this formula we got:

[tex](\frac{5}{13})^2+(\frac{y}{13})^2=1[/tex]

And we can solve for y:

[tex]\frac{y^2}{169}=1-\frac{25}{169}=\frac{144}{169}[/tex]

And solving for y we got:

[tex]y=\sqrt{169\cdot\frac{144}{169}}=\sqrt{144}=\pm12[/tex]

And the two possible solutions for this case are y=12 and y=-12

Tim is building a model of a castle with small wooden cubes. So far Tim has constructed part of a security world castle,as shown below. Each wooden cube has a side length of 1/8ft

Answers

From the given model, the length of the wall is 9/8 ft, the width of the walk is 1/2 ft, and the height of the wall is 11/8. The volume of the portion of security wall that Tim has constructed so far is 99/128 cu ft.

What is the Volume of the Block?

From the given image of the building model we see that part of a security world castle is shown.

We see that the length has 9 blocks.

Since the length has a total of 9 blocks and each side length is 1/8 ft, then we say that;

Length =  9*(1/8) = 9/8 ft

We also observe that the height has 11 blocks and as such;

height = 11*(1/8) = 11/8 ft

Meanwhile the width will have a length of: 1/2 ft

Formula for volume is;

Volume = length * height * width

Thus;

Volume = (9/8) * (11/8) * (1/2)

Volume = (9 * 11 * 1)/(8 * 8 * 2)

Volume = 99/128 cu ft

Solution

We are given the arithmetic sequence

[tex]\begin{gathered} a_1=5 \\ a_n=a_{n-1}-4 \end{gathered}[/tex]

To find an explicit formula

[tex]\begin{gathered} First\text{ }Term=5 \\ a=5 \end{gathered}[/tex]

From the second recursive formula

[tex]\begin{gathered} a_n-a_{n-1}=-4 \\ Common\text{ }Difference=-4 \\ d=-4 \end{gathered}[/tex]

The nth term of an Arithmetic sequence is given by

[tex]\begin{gathered} a_n=a+(n-1)d \\ a_n=5+(n-1)(-4) \end{gathered}[/tex]

Therefore, the answer is

[tex]a_{n}=5+(n-1)(-4)[/tex]

Answers

The kilometers that the red car travel in 12 hours is 2604 kilometers.

What is an equation?

An equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario. It is vital to note that an equation is a mathematical statement which is made up of two expressions that are connected by an equal sign.

From the diagram, it should be noted that the red car has a speed of 217 km per hours.

Therefore, the distance traveled in 12 hours will be:

Distance = Speed × Time

= 217 × 12

= 2604 km
