Answer:

The total surface area of triangular prism

A = 232 foot²

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given bases of prism 5 f t , 5 f t , 7 f t

The perimeter of the sum of the bases

P = 7 + 5 +5 = 17 f t

Lateral surface area =perimeter X height

= 1 7 × 8

= 136 f t²

Base area of the triangular prism = $\frac{1}{2} h ( b_{1} + b_{2} ) = \frac{1}{2} 8 ( 5 +7) =48$

The total surface area of triangular prism

$A = p h + 2 Base Area$

$A = p h + 2 Base Area = 136 + 2 ( 4 8 ) = 232$

The total surface area of triangular prism

A = 232 foot²

if (20,14) is an ordered pair of the inverse of f(x) which of the following is an ordered pair of the function f(x)

Strike441 [17]

<h3>(14, 20) is the ordered pair of the function f(x)</h3>

<em><u>Solution:</u></em>

Given that,

(20, 14) is an ordered pair of the inverse of f(x)

We have to find the ordered pair of the function f(x)

In an inverse funciton, the domain of f(x) becomes the range and range of f(x) becomes the domain

To find the ordered pair of the function f(x), we swap the variables x and y

(y, x) of inverse of f(x) becomes (x, y) of f(x)

Therefore, (14, 20) is the ordered pair of the function f(x)

What is the answer to -5f=-3(8-f)

Semmy [17]

Answer:

Step-by-step explanation:

-5f=-3(8-f)

Opening bracket

-5f = - 24 + 3f

Collecting like terms

-5f - 3f = -24

-8f = -24

Dividing by -8

f = -24/-8

f = 3

a rectangular lawn has an area of a^3 - 125. use the difference of cubes to find out the dimensions of the rectangle.

ANEK [815]

The area of a rectangle is the product of its dimensions

The dimensions of the rectangle are: $\mathbf{Length = a -5}$ and $\mathbf{Width = a^2 + 5a + 25}$

The area is given as:

$\mathbf{Area = a^3 - 125}$

Express 125 as 5^3

$\mathbf{Area = a^3 - 5^3}$

Apply difference of cubes

$\mathbf{Area = (a - 5)(a^2 + 5a + 5^2)}$

$\mathbf{Area = (a - 5)(a^2 + 5a + 25)}$

The area of a rectangle is:

$\mathbf{Area = Length \times Width}$

So, by comparison:

$\mathbf{Length = a -5}$

$\mathbf{Width = a^2 + 5a + 25}$
