Answers

Answer 1

Answer:

Step-by-step explanation:

Coordinates of the original down ward parabola are ( - 10, - 7 )

Coordinates of the image upward parabola are ( - 10, 7 )

g(x) = 8( x + 10 )² + 7

Answer 2

For a reflection of parabola across x axis the rule is

a=-ak=-k

Means a turns negative

y=-8(x+10)²-7

Here a is -8

Turn negative

-(-8)=8

k is -7

turn negative

-(-7)=7

New one

g(x)=8(x+10)²+7

Answers

Answer:

[tex]\textsf{a)} \quad y=(x+1)^2-4[/tex]

[tex]\textsf{b)} \quad y=2(x-4)^2-2[/tex]

Step-by-step explanation:

Vertex form of a parabola: [tex]y=a(x-h)^2+k[/tex]

(where (h, k) is the vertex and [tex]a[/tex] is some constant)

Part aVertex = (-1, -4)Point on parabola = (1, 0)

Substitute the vertex into the formula:

[tex]\begin{aligned}\implies y &=a(x-(-1))^2-4\\y & =a(x+1)^2-4\end{aligned}[/tex]

Substitute the point (1, 0) into the formula:

[tex]\begin{aligned}\implies a(1+1)^2-4&=0\\4a-4&=0\\4a &=4\\a &=1\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=(x+1)^2-4[/tex]

Part bVertex = (4, -2)Point on parabola = (6, 6)

Substitute the vertex into the formula:

[tex]\begin{aligned}\implies y &=a(x-4)^2+(-2)\\y & =a(x-4)^2-2\end{aligned}[/tex]

Substitute the point (6, 6) into the formula:

[tex]\begin{aligned}\implies a(6-4)^2-2&=6\\4a-2 & =6\\4a &=8\\a &=2\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=2(x-4)^2-2[/tex]

Vertex at (-1,-4)Passes through (1,0)

Find a

a(x-h)²+k=ya(1+1)²-4=04a-4=04a=4a=1

Vertex form

y=(x+1)²-4

(h,k)=(4,-2)passes through (6,6)

Find a

a(6-4)²-2=64a=8a=2

Vertex form

y=2(x-4)²-2

Sean is building nesting boxes for their Etsy store. The smallest box is a cube, 10 cm on a side. It fits entirely inside a larger cubic box that is 15.0 cm on a side (50% larger). If each box has dimensions that are 50% larger than the one before then what is the total maximum number of nesting boxes Sean can build that will fit inside a shipping carton that has a cube-shaped interior, 1 m (100 cm) on a side?

Answers

Answer:

Step-by-step explanation:

I don't really have explanation but imagine putting boxes into boxes that are always a little bigger(+5 cm)

so you go from the smallest one 10cm and gradually keep adding 5cm until you reach 100cm.

You want to know the opinions of homo-schooled students across America on whether they prefer to loarn at home versus at a public school with other students. You obtain a list of all home-schooled students and mail a survey to a random sample of 7,500 students. Of those, 4,195 responded and 39% say they prefer to learn at home. Which of the
following statements is true?
The results of this survey may be affected by nonresponse blas.
The results of this survey cannot be trusted because of convenience response bias.
O Bocauso random sampling is used, wo can fool confident that the porcont of all homo-schooled students who say they favor learning at home is close to 39%.
O Because more than half of those who were mailed the survey actually responded, va can feel fairly confident that the actual percentage of all home-schooled
students who prefer to learn at homo is close to 39%.

Answers

In this survey, the results can be trusted because more than half of the people responded which makes this sample to be representative.

What is nonresponse bias?

This occurs when most of the people who were intended to be surveyed do not respond, which causes the results to be biased as the sample does not represent the population.

Can the results of this survey be trusted?

Considering more than 50% answer it is likely the results can be trusted as the sample is still representative.

A certain rectangular prism has a height of 4 m, a length of 6 m, and a width of 8 m. Give the dimensions of a second rectangular prism that will have the same surface area of the first one.

Answers

Step-by-step explanation:

in its basic structure such a prism is like a cube (just rectangular and not squared) : 6 sides (rectangles).

2 rectangles top and bottom 6×8 = 48 m²

48 × 2 = 96 m²

2 rectangles front and back 6×4 = 24 m²

24 × 2 = 48 m²

2 rectangles left and right 8×4 = 32 m²

32 × 2 = 64 m²

the total surface area is

96 + 48 + 64 = 208 m²

it is hard to find other integer dimensions for the same surface area.

but as long as we are not restricted to integer numbers :

let's cut e.g. the height in half.

and we get

2 rectangles left and right 8×2 = 16 m²

16 × 2 = 32 m²

that "nails" already 2 dimensions (width and height).

we need to set now the third dimension (length) to create the same surface area :

length×8×2 + length×2×2 = 208 - 32 = 176

20×length = 176

length = 8.8 m

so, with

length = 8.8 m

width = 8 m

height = 2 m

we still get

2 rectangles top and bottom 8.8×8 = 70.4 m²

70.4 × 2 = 140.8 m²

2 rectangles front and back 8.8×2 = 17.6 m²

17.6 × 2 = 35.2 m²

2 rectangles left and right 8×2 = 16 m²

16 × 2 = 32 m²

as total surface area

140.8 + 35.2 + 32 = 208 m²

Answers

Using the z-distribution, it is found that the desired measures are given as follows:

The test statistic is z = -0.795.The p-value is of 0.2133.

What are the hypotheses tested?

At the null hypotheses, it is tested if the mean is of 61.5, that is:

[tex]H_0: \mu = 61.5[/tex]

At the alternative hypotheses, it is tested if the mean is less than 61.5, that is:

[tex]H_1: \mu < 61.5[/tex]

What is the test statistic?

The test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

The parameters are:

[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.[tex]\sigma[/tex] is the standard deviation of the population.n is the sample size.

The values of the parameters are given as follows:

[tex]\overline{x} = 59.1, \mu = 61.5, \sigma = 17.6, n = 34[/tex]

Hence, the test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{59.1 - 61.5}{\frac{17.6}{\sqrt{34}}}[/tex]

z = -0.795.

What is the p-value?

We have a left-tailed test, as we are testing if the mean is less than a value, with z = -0.795. Hence, using a z-distribution calculator, the p-value is of 0.2133.

The circumference of a circle is 25 pi cm . what is the area, in square centimeters? express your answer in terms of pi .

Answers

The area of the circle is the amount of space it occupies, and the area of the circle is 156.25π

How to determine the area?

The circumference, C is given as:

C = 25π

Start by calculating the radius using:

C = 2πr

So, we have:

2πr = 25π

Solve for r

r = 12.5

The area is then calculated using:

A = πr²

So, we have:

A = π * 12.5²

Evaluate

A = 156.25π

Hence, the area of the circle is 156.25π
