10 square units.

Step-by-step explanation:

Remark

No matter how weird it looks, the figure is a trapezoid. It has 2 parallel lines.

The height has 2 right angles, one at each end.

Givens

b1 = 2

b2 = 8

h = 2

Formula

Area = 1/2 * (b1 + b2 ) * h

Solution

Area = 1/2 * (2 + 4 + 2 + 2) * 2    Be sure you understand where all those 2s came from.

Area = 10 square units

Step-by-step explanation:

x1 / y1    times x2 / y2       where are two fractions

x1/y1 times x2/y2   = x1 times x2 / y1 times y2   = z1 / z2    z is a new fraction

fractions multiply like regular wholes number, which can also be represented in fractional form

Examples:

2/1   times 3/1 = 2x3 /1x1   6/1

10/2 x 18/3 = 180/6     now look at 10/2 = 5     18/3 = 6    5x6 =  30    

  5  x    6    = 30

Now apply to your fractions:

3/7 x 4/5   =   3x4 / 7x5    

12/35  

9s is correct

Step-by-step explanation:

Because 12 divide by 4 is three

Step-by-step explanation:

the other parts base on A and B ...

but ok.

A.

the hourly rate is

15 monetary units / hour

B.

we get A actually from here :

small triangle : 15/1 or 15:1

medium triangle : 30/2 or 30:2 = 15:1

large triangle : 60/4 or 60:4 = 15:1

so, we see it all boils down to 15 monetary units to (or per) 1 hour.

Answer:

Population mean = 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]

Step-by-step explanation:

Given - A university researcher wants to estimate the mean number

            of  novels that seniors read during their time in college. An exit

            survey was conducted with a random sample of 9 seniors. The

            sample mean was 7 novels with standard deviation 2.29 novels.

To find - Assuming that all conditions for conducting inference have

              been met, which of the following is a 94.645% confidence

              interval for the population mean number of novels read by

              all seniors?

Proof -

Given that,

Mean ,x⁻ = 7

Standard deviation, s = 2.29

Size, n = 9

Now,

Degrees of freedom = df

                                = n - 1

                                = 9 - 1

                                = 8

⇒Degrees of freedom = 8

Now,

At 94.645% confidence level

α = 1 - 94.645%

   =1 - 0.94645

  =0.05355 ≈ 0.05

⇒α = 0.5

Now,

[tex]\frac{\alpha}{2} = \frac{0.05}{2}[/tex]

  = 0.025

Then,

[tex]t_{\frac{\alpha}{2}, df }[/tex]  = 2.306

∴ we get

Population mean = x⁻ ± [tex]t_{\frac{\alpha}{2}, df }[/tex] ×[tex]\frac{s}{\sqrt{n} }[/tex]

                           = 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]

⇒Population mean = 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]

Answer: C

Step-by-step explanation:

Hello! :)

[tex]\large\boxed{\text{m = -8, b = 22}}[/tex]

Find the slope and y-intercept by rearranging the equation into the following format:

y = mx + b

We are given the equation:

16x + 2y = 44

Rearrange by subtracting 16x from both sides:

2y = -16x + 44

Divide all terms by 2:

y = -8x + 22

In this equation, the m-value is -8 and the b value is 22.

Therefore, m = -8, and b = 22.

Answer:

1. 9/2 is the slope.

2. 22 is the intercept on the y-axis

Step-by-step explanation:

From the question given above, the following equation was obtained:

y = 9/2x + 22

1. Determination of the meaning of 9/2

y = 9/2x + 22

Comparing the above equation with:

y = mx + c

m => is the slope

y = 9/2x + 22

y = mx + c

mx + c = 9/2x + 22

Slope (m) = 9/2

Therefore, 9/2 is the slope.

2. Determination of the meaning of 22

y = 9/2x + 22

Comparing the above equation with:

y = mx + c

c => is the intercept on y-axis

y = 9/2x + 22

y = mx + c

mx + c = 9/2x + 22

Intercept (c) = 22

Therefore, 22 is the intercept on the y-axis

Answer: Option D.

Step-by-step explanation:

A straightforward way to solve this type of problems is to expand all the options and see which one fits the desired one.

First let's see which options we can discard.

The original polynomial is:

p(x) = 2*x^5 + 12*x^3 - 54*x

So the degree of this polynomial is 5.

We can see that in option B we have only 3 "x", then the degree of this polynomial will be 3, then this option can be discarded.

Now let's try with the other 3 options:

A) = 2*x*(x^2 - 3)*(x + 9)*(x - 9)

    = 2*x*(x^2 -  3)*(x^2 - 81)

    = (2*x^3 - 6*x)*(x^2 - 81)

    = 2*x^5 - (2*x^3)*81 - 6*x^3 + 6*x*81

    = 2*x^5  -168*x^3 + 486*x

We can see that the second and third coefficients are different than the ones we wanted, so this is not the correct option.

Now let's try option D.

D) = 2*x*(x^2 - 3)*(x^2 + 9)

    = 2*x*(x^4 - 3*x^2 + 9*x^2 - 27) = 2*x*(x^4 + 6*x^2 - 27)

    = 2*x^5 + 2*6*x^3 - (27)*2x

    = 2*x^5 + 12*x^3 - 54*x

This is exactly what we wanted, so we can conclude that the correct option is D.

Step-by-step explanation:

The height of given hexagonal prism is 7x³+4x²-3x+5.

Given that, the volume of a hexagonal prism is [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] and the area of the base is 5x² - 6.

A hexagonal prism is a three-dimensional solid shape with 8 faces that including hexagon bases.

Volume of a hexagonal prism = Area of a base × Height.

Here, [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] = 5x² - 6 × Height

Height = [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] ÷ 5x² - 6

5x² - 6| [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] | 7x³+4x²-3x+5
