6) What is the equation of the following graphed function?Is the vertex a maximum or minimum?What are the solutions to the function?What is the y-intercept?уmobruo uove56$ x

Answers

If we know the roots (solutions) we can find the equation of the second-degree function using the formula above:

[tex]f(x)=a(x-x_1)(x-x_2)[/tex]

In this case, a = -1, x1 = 2 and x2 = 4. Therefore the equation will be:

[tex]f(x)=-1(x-2_{})(x-4_{})[/tex][tex]f(x)=-x^2+6x-8[/tex]

The vertex is maximum (see that the function has a clear max value).

The solutions to the function are the roots (place in the x-axis where the function cross). They are 2 and 4.

The y-intercept is the point with the format (0,y). Thus to find this point we can substitute 0 into the function:

[tex]f(0)=-0^2+6\times0-8[/tex][tex]f(0)=-8[/tex]

The y-intercept will be y = -8.

Two number cubes are rolled what is the probability that the sum of the numbers rolled is either a 1 and a 4 in either order

Answers

The first thing we have to know is that a cube with numbers is a dice that has 6 faces and that its numbers go from 1 to 6, so the probability that the sum of both dice gives 1 is zero, since the minimum that we are going to give is 2

[tex]P(sum=1)=0[/tex]

Now for the sum of both dice of 4 we have the following combinations

• 1 and 3

,

• 3 and 1

,

• 2 and 2

We have 3 combinatorics that we have to get the probability of each of the combinations in order to find our final probability

[tex]\begin{gathered} P(1|3)=P(1)P(3)=\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{36} \\ P(3|1)=P(3)P(1)=\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{36} \\ P(2|2)=P(2)P(2)=\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{36} \end{gathered}[/tex]

The probability that the sum of 4 would be the sum of the probabilities of the combinatorcs

[tex]\begin{gathered} P(sum=4)=P(1|3)+P(3|1)+P(2|2) \\ P(sum=4)=\frac{1}{36}+\frac{1}{36}+\frac{1}{36} \\ P(sum=4)=\frac{3}{36} \\ P(sum=4)=\frac{1}{12} \end{gathered}[/tex]What is the probability of getting a 1 and a 4 in either order?

The probability of getting any number on a die will be 1/6 if we can get a 1 or a 4 then our population will be 2/6

Julia has been measuring the length of her baby's hair. The first time it was 6 cm long and after one month it was 2 cm longer. If the hair continues to grow at this rate, determine the function that represents the hair growth and graph it.

Answers

Given that,

The length of baby's hair at first time = 6cm

After a month, the length was 2 cm longer = 6 + 2 = 8 cm

As mentioned in the question, the hair continues to grow at this rate. Therefore, after two months, the length would be = 8 + 2 = 10 cm

It results in a sequence with a common difference of 2,

6, 8, 10, 12, ............

If a sequence has a common difference, it is called an arithmetic sequence. In such sequences, the nth term is calculated as:

an = a1 + (n-1)*d

Here,

a1 = first term = 6

d = common difference = 2. (8-6 or 10 - 8 = 2)

Now, put all the values in the equation,

an = a1 + (n-1)*d

an = 6 + (n-1)*2

an = 6 + 2n - 2

an = 2n + 4

an = 2(n+2)

Hence, the function that represents growth is an = 2(n+2).

By varying the value of 'n', you can get the values of 'an'. Both will generate ordered pairs that will help you in plotting. For example:

n = 1

an = 2(n+2) = 2(1+2) = 2 (3) = 6

=> ordered pair (1, 6)

n = 2

an = 2(n+2) = 2(2+2) = 2 (4) = 8

=> ordered pair (2, 8)

n = 3

an = 2(n+2) = 2(3+2) = 2 (5) = 10

=> ordered pair (3, 10)

n = 4

an = 2(n+2) = 2(4+2) = 2 (6) = 12

=> ordered pair (4, 12)

With the ordered pairs, you can plot the graph.

We have to sum these fractions with the cross-rule. The image below shows this method.

The question is in the picture. Using the answer choice word bank, fill in the proportion to find the volume of the larger figure.

Answers

It is given that two similar solids have surface areas of 48 m² and 147 m², and the smaller solid has a volume of 34 m³.

It is required to find the volume of the larger solid.

Recall that the if the scale factor of similar solids is a/b, then the ratio of their areas is the square of the scale factor:

[tex]\frac{\text{ Area of smaller solid}}{\text{ Area of larger solid}}=\frac{a^2}{b^2}[/tex]

Substitute the given areas into the equation:

[tex]\frac{48}{147}=\frac{a^2}{b^2}[/tex]

Find the scale factor a/b:

[tex]\begin{gathered} \text{ Swap the sides of the equation:} \\ \Rightarrow\frac{a^2}{b^2}=\frac{48}{147} \\ \text{ Reduce the fraction on the right with }3: \\ \Rightarrow\frac{a^2}{b^2}=\frac{16}{49} \\ \text{ Take the square root of both sides:} \\ \Rightarrow\frac{a}{b}=\frac{4}{7} \end{gathered}[/tex]

Recall that if the scale factor of two similar solids is a/b, then the ratio of their volumes is the cube of the scale factor:

[tex]\frac{\text{ Volume of smaller solid}}{\text{ Volume of larger solid}}=\left(\frac{a}{b}\right)^3[/tex]

Let the volume of the larger solid be V and substitute the given value for the volume of the smaller solid:

[tex]\frac{34}{V}=\left(\frac{a}{b}\right)^3[/tex]

Substitute a/b=4/7 into the proportion:

[tex]\begin{gathered} \frac{34}{V}=\left(\frac{4}{7}\right)^3 \\ \\ \Rightarrow\frac{34}{V}=\frac{4^3}{7^3} \\ \\ \Rightarrow\frac{34}{V}=\frac{64}{343} \end{gathered}[/tex]

Find the value of V in the resulting proportion:

[tex]\begin{gathered} \text{ Cross multiply:} \\ 64V=343\cdot34 \\ \text{ Divide both sides by }64: \\ \Rightarrow\frac{64V}{64}=\frac{343\cdot34}{64} \\ \Rightarrow V\approx182.22\text{ m}^3 \end{gathered}[/tex]

Write and equation of a line that passes through the point (5, -9) and is perpendicular to the line 2x + 11y = 22

Answers

The general equation of the line in slope - intercept form is :

[tex]y=m\cdot x+b[/tex]

Where m is the slope and b is y - intercept

Given the line : 2x + 11y = 22​

We need to write it in slope - intercept form to find the slope of it

so,

[tex]\begin{gathered} 2x+11y=22​ \\ 11y=-2x+22 \\ y=-\frac{2}{11}x+2 \end{gathered}[/tex]

So, the slope of the given line = -2/11

The required line is perpendicular to the given line

So, the product of the slope of the two lines = -1

So, if the slope of the given line is m , the slope of the required line will be = -1/m

So, the slope of the required line = 11/2

The equation of the required line will be :

[tex]y=\frac{11}{2}x+b[/tex]

Using the given point ( 5 , -9 ) to find the value of b

So, when x = 5 , y = -9

[tex]\begin{gathered} -9=\frac{11}{2}\cdot5+b \\ -9=\frac{55}{2}+b \\ b=-9-\frac{55}{2}=-\frac{73}{2} \end{gathered}[/tex]

so, the equation of the line is :

[tex]y=\frac{11}{2}x-\frac{73}{2}[/tex]

And the standard form will be :

[tex]\begin{gathered} 2y=11x-73 \\ \\ 11x-2y=73 \end{gathered}[/tex]

Answers

Given:

Cost of students tickets is, c (s) = $8.

Cost of adult tickets is, c (a) = $10.

Total cost collected for by selling the tickets is, c (t) = $1,760.

Number of tickets sold is, n = 200.

The objective is to find the system of equations that can model the number of students and adults tickets sold at the booth.

A cylinder shaped above ground pool is 4.5 deep. If the diameter of the pool is 16 ft, determine the capacity of the swimming pool in cubic feet. Write your awnser in terms of pi

Answers

For this exercise you need to use the following formula for calculate the volume of a cylinder:

[tex]V=\pi r^2h[/tex]

Where "r" is the radius and "h" is the height of the cylinder.

In this case you can identify that:

[tex]h=4.5ft[/tex]

You know that the diameter of the pool is 16 feet. Since the radius is half the diameter:

[tex]\begin{gathered} r=\frac{16ft}{2} \\ \\ r=8ft \end{gathered}[/tex]

Knowing the radius and the height of the pool, you can substitute them into the formula and then you have to evaluate, in order to find the capacity of the swimming pool in cubic feet:

[tex]\begin{gathered} V=\pi(8ft)^2(4.5ft) \\ V=288\pi\text{ }ft^3 \end{gathered}[/tex]

Point O is the center of this circle. What is m

Answers

The value of the angle ∠CAB subtended at the circumference of the circle is 48° .

It is given that the center of the circle is at O.

∠AOB = 96° .

We know that the angle subtended by an arc at the center is twice that subtended at the circumference.

Therefore ∠CAB = 1/2 of ∠AOB

or,  ∠CAB = 1/2 × 96°

or,  ∠CAB = 48°

An arc is any segment of a circle's circumference. The angle formed by the two line segments joining a point to an arc's endpoints at any given position is known as the arc's angle.

The circle in the following illustration features an arc that subtends an angle at both the center O and a point on the circumference AB is a chord.

The angle of an arc at the center of a circle is twice as large as its angle elsewhere on the circle's edge.

Therefore the value of ∠CAB is 48° .

A science fair poster is a rectangle 36 inches long and 24 inches wide what is the area of the poster in square feet with sure to include the correct unit in your answer

Answers

Okay, here we have this:

Considering the provided information, we are going to calculate the area of the rectangle ins square inches and after we are going to convert it to square feet, so we obtain the following:

Area of the rectangle=36 inches * 24 inches = 864 square inches

Now, let's convert it to square feet, then we have:

[tex]\begin{gathered} 864in^2\cdot\frac{1ft^2}{144in^2} \\ =6ft^2 \end{gathered}[/tex]

Finally we obtain that the area in square feet of the rectangle is 6 square feet.

Explain how to estimate the product ofof 12 3/8 x 6 7/8Use complete sentences in your answer.

Answers

Given:

12 3/8 x 6 7/8

We can round 12 3/8 down to 12 because converting 12 3/8 to decimal will give 12.375.

We can round up 6 7/8 which is equivalent to 6.875 to 7

Hence, the estimate is 12 x 7 = 84
