Step-by-step explanation:
Find the area of each shape and add.Let's start with the first semi-circle(half-circle)
If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters
A=1/2πr²
A=1/2*22/7*1.8*1.8
A=5.09 m²(rounded to nearest hundredth)
Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again.
So 5.09 *2=10.18meters square is the area of the two semi-circles
Now, let's find the area of a rectangle which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters
A=l*w
A=6*3.6
A=21.6meters square
Therefore the area of the shape is 10.18m²+21.6m²=219.888m²
I think its 24% because .24 x 50 is 12 but I could be doing it wrong, sorry I can't say for sure.
Answer:
f(x) = 4x^2 -8x -32
Step-by-step explanation:
If "a" is a zero, then (x -a) is a factor. For some scale factor k, the equation can be written ...
f(x) = k(x +2)(x -4)
We want f(0) = -32, so ...
f(0) = -32 = k(0 +2)(0 -4) = -8k
4 = k . . . . . divide by -8
Then the factored equation is ...
f(x) = 4(x +2)(x -4)
Multiplying it out gives ...
f(x) = 4x^2 -8x -32
