Answer:

16 feet

Step-by-step explanation:

We are Given that

  • We have a 34 foot ladder leaning against a 30 foot building
  • We are asked to find the distance of the bottom ladder from bottom of the building.

A ladder leaning against a object makes the ladder slanted so that means 34 is our hypotense.

The building height And distance of the bottom of ladder and building is our legs so our formula we use is

{30}^{2}  +  {x}^{2}  =  {34}^{2}

900 +  {x}^{2}  = 1156

{x}^{2}  = 256

x = 16

Use the graph shown to evaluate the composition <br><br>(f○g)(0)
andrey2020 [161]

<u>Function</u> <u>composition</u> is applying one function to the <u>results</u> of another:

\rightarrow g(x)\rightarrow f(x)\rightarrow

This means the result of g() is sent through f(). Written notation for the composition is

(f\circ g)(x)=f(g(x)).

Note that g(0)=2, then

(f\circ g)(0)=f(g(0))=f(2).

Since f(2)=3, then

(f\circ g)(0)=f(2)=3.

Answer: (f\circ g)(0)=3.

|8w+5|=21 <br> please show work
Gre4nikov [31]

Answer:

w=-13/4

w=2

Step-by-step explanation:

|8w+5|=21

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |8w+5| = 21

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |8w+5|

For the Negative case we'll use -(8w+5)

For the Positive case we'll use (8w+5)

STEP

3

:

Solve the Negative Case

     -(8w+5) = 21

    Multiply

     -8w-5 = 21

    Rearrange and Add up

     -8w = 26

    Divide both sides by 8

     -w = (13/4)

    Multiply both sides by (-1)

     w = -(13/4)

    Which is the solution for the Negative Case

STEP

4

:

Solve the Positive Case

     (8w+5) = 21

    Rearrange and Add up

     8w = 16

    Divide both sides by 8

     w = 2

    Which is the solution for the Positive Case

STEP

5

:

Wrap up the solution

w=-13/4

w=2

Any help would be GREAT!!!
docker41 [41]
The answer is  B. 9

(g o f)(x) = g(f(x))

f(x) = x + 2
f(-5) = -5 + 2 = -3

g(x) = x²
(g o f)(-5) = g(f(-5)) = g(-3) = (-3)² = 9
