Evaluate f(x) = 2|x – 5| for f(–5) and f(0).
Elanso [62]

Answer:

f(–5) = 20, f(0) = 10

Step-by-step explanation:

f(-5):

f(-5) = 2|-5 -5|

f(-5) = 2|-10|

f(-5) = 2(10)

f(-5) = 20

f(0):

f(0) = 2|0 - 5|

f(0) = 2|-5|

f(0) = 2(5)

f(0) = 10

Please help solve!!!!!!!!!!
Deffense [45]

Answer:

Height = 17.31821 feet

Step-by-step explanation:

<u><em>Explanation</em></u>

<u><em>From graph</em></u>

Given angle θ = 6.5°  and a = 152 feet

we need to find the height (h)

By using the tangent rule

                   tan \alpha = \frac{opposite side}{adjacent side}

                  tan 6.5 = \frac{b}{152}

    Cross multiplication , we get

               b = 152 × tan 6.5°

               b = 152 × 0.113935

              b = 17.31821 feet

Height = 17.31821 feet
