Answer:
I got x1 =0 x2=220
Step-by-step explanation:
y=- 00.1x (x-220)
-0.01x (x-220)=0
- 1/100 x(x-220)=0
x (x-220)=0
x=0
x-220=0
Answer x=0 and x=220
Answer: The solids have the same types of vertical cross sections through the base are a rectangular prism and a cylinder (first option)
Solution:
a. The vertical cross section through the base of a rectangular prism is a rectangle.
b. The vertical cross section through the base of a cylinder is a rectangle.
c. The vertical cross section through the base of a cone is a triangle.
d. The vertical cross section through the base of a pyramid is a triangle.
Then:
First option is true.
Second option is false.
Third option is false.
Fourth option is false.
Assuming you want to solve for a, then
ad - 7 = y (reversing the equation to have a on left side )
add 7 to both sides to isolate the term with a
ad = y + 7 ( divide both sides by d )
a = 
Answer:
C has the largest area. It is 4.5 square units.
Step-by-step explanation:
A:
area = bh/2 = 2 * 3/2 = 3
B:
area = bh/2 = 2 * 3/2 = 3
C:
area = bh/2 = 3 * 3/2 = 4.5
C has the largest area. It is 4.5 square units.
