What is the surface area of the triangular prism?

TiliK225 [7]

Answer:

Step-by-step explanation:

surface area = bh + L(s1 + s2 + s3)

where b = 24 ft.

h = 9 ft.

s1 = 15 ft.

s2 = 15 ft.

s3 = 24 ft.

L = 40 ft.

<u>plugin values into the formula:</u>

A = 24*9 + 40(15 + 15 + 24)

= 216 + 40(54)

= 2,376 ft²

Which table shows a proportional relationship between x and y

Tomtit [17]

Answer:

The answer is B (1 , 3) , (2 , 6) , (4 , 12) , (5 , 15)

Step-by-step explanation:

∵ X : 1 , 2 , 4 , 5

∵ Y : 3 , 6 , 12 , 15

∵ 2/6 = 1/3

∵ 4/12 = 1/3

∵ 5/15 = 1/3

∴ 1/3 = 2/6= 4/12 = 5/15 = 1/3 ⇒ all are proportion

∴ Answer B is in proportional relationship

Which expression below gives the average rate of change of the function h(x)=4^(x+2)+7 on the interval –3 ≤ x ≤ 5?

viktelen [127]

Answer:

$\frac{4^8-1}{32}$

Step-by-step explanation:

$h(x)=4^{(x+2)} +7$

We know that formula for average rate of change of a function from a to b is

$\frac{f(b)-f(a)}{b-a}$

Here f equals h and a =-3 b=5

h(a) = $4^{5+2} +7 = 4^7+7$

and

h(b) = $4^{-3+2} +7 = \frac{1}{4} +7$

h(b)-h(a) = $4^7-\frac{1}{4} =\frac{4^8-1}{4}$

b-a = 5-(-3) =8

Hence average rate of change is

$\frac{4^8-1}{4}(\frac{1}{8} )=\frac{4^8-1}{32}$

R - 17.1 = -4.8

denis-greek [22]

<u><em>Answer: r=12.3 *The answer must have a positive sign or decimal point.*</em></u>

Explanation:

First, you had to do is add 17.1 from both sides of an equation.

$r-17.1+17.1=-4.8+17.1$

And then, simplify by equation.

$17.1+-4.8=12.3$

You can also add by the numbers.

$12.3+4.8=17.1$

$r=12.3$

Hope this helps!
