Answer: Brand B is the best unit price
Explanation:
Brand A:
6 = 54$
1 = 54/6
1 = 9$
Brand B:
9 = 63$
1 = 63/9
1 = 7
So brand B is much cheaper
Each domain of the points can only have one unique range
Which point doesn’t have multiply ranges for a x value?
Solution: A
With this function you are given 2 x's and all we have to do is plug those X's into the function so
f(-1)=4*7^-1
7^-1 is 1/7
times 4 = 4/7
f(2)=4*7^2
7^2=49 *4 = 196
The problem ask to find the are of the shaded region of the circle which has a radius of 12cm. The are of the circle is computed as the formula of pie times the square of the radius so the are of the circle would be 452.389 cm2 and the area of the shaded region would be 150.796 cm2^2. I hope you are satisfied with my answer and feel free to ask for more
PART A
rectangle : circle
5:13
PART B
5x3 : 13x3
