Answer:
B and C
Step-by-step explanation:
The correct options are :
A cross-section that is perpendicular to the base of a cube.
A cross-section that is perpendicular to the base of a cylinder whose base diameter and height are the same.
In both the cases the length and the width of the section are equal
Answer:
vertex = (- 1, - 4.5 )
Step-by-step explanation:
Given
f(x) = 
(x - 2)(x + 4)
The vertex lies on the axis of symmetry which is positioned at the midpoint of the zeros.
To find the zeros let f(x) = 0, that is
(x - 2)(x + 4) = 0
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x + 4 = 0 ⇒ x = - 4
The x- coordinate of the vertex is therefore
x = 
= 
= - 1
Substitute x = - 1 into f(x) for corresponding y- coordinate
f(- 1) = (- 1 - 2)(- 1 + 4) = × - 3 × 3 = 0.5 × - 9 = - 4.5
Coordinates of vertex = (- 1, - 4.5 )

Answer:
Below
Step-by-step explanation:
Sale price of each tire : $92.99 - $20 = 72.99. The cost of x tires is 72.99x
If the sales tax is 4% there is an additional (72.99x)(1.04)
Here is the equation
= (72.99)(1.04) t
If Patrick bought 8 tires.....
= (72.99)(1.04)(8)
= $607.2768
Hope this helps!
