Answer:
B) -4
Step-by-step explanation:
To solve g(f(3)), we first have to solve f(3):
Since f(x) = -x +4 , f(3) = -3 + 4 = 1
Now we have to solve g(1) , since that is what f(3) left us;
Since g(x) = x^2 - 5 , g(1) = 1^2 - 5 = 1 - 5 = -4
Try a calculator and doing some googling of numbers divisible by six. There's a great calculator site called calculator soup! ( Yes it's really called calculator soup )
Answer:
<h2>The height is 10 m</h2>
Step-by-step explanation:
Area of a trapezoid is given by
<h3>

</h3>
where
a and b are the bases
h is the height
From the question
A = 135 m²
a = 20m
b = 7 m
Substitute the values into the above formula and solve for the height
That's
<h3>

</h3>
<u>Divide both sides by 27</u>
That's
<h3>

</h3>
We have the final answer as
<h3>10 m</h3>
