F(x)=x^2+2x-10
f(-2)=4-4-10
f(-2)=-10
the answer is A) or -10
To find the diameter of a circle using only the circumference, you need to use this formula: d=C/<span>π </span><span>
so it should go like:
d=33/3.14
</span>
d=10.51
The length of each side of the square is 3 ft.
<u>Step-by-step explanation:</u>
We have , A composite figure is formed by combining a square and a triangle. Its total area is 52.5 ft. The area of the triangle is 43.5 ft . We know that area of a square =
. According to question:
area of square = 
area of triangle = 43.5 ft
total area = 52.5 ft.
Total area = area(square+triangle)
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, the length of each side of the square is 3 ft.
Answer:
the first option = 437.4 sq.ft
Step-by-step explanation:
the formula of an are of circle =
A = (pie) (radius) ^2
so fill it, (3.142 × 11.8)^2
and you will got the answer = 437.44
and round it to nearest tenth = 437.4
done!
