Answer:
(0 , -a²)
Step-by-step explanation:
tangent at x = a and x = -a
y = x² (a , a²) and (-a , a²) must be on the curve and tangent to curve
gradient dy/dx = 2x
slope (m) at x = a is <u>2a</u> and slope (m') at x=-a is<u> -2a</u>
line1: (y - a²) / (x - a) = 2a
y - a² = 2a (x - a) y = 2ax - a² ... (1)
line2: (y - a²) / (x + a) = - 2a y = -2ax- a² ... (2)
(1) - (2): 4ax = 0 a≠0 x = 0
y = - a²

Answer:
Step-by-step explanation:
The formula to find the volume of a rectangular prism such as this is :
V = length * width * depth
To solve for this problem, we just plug in the values and multiply it all out.
=
Therefore, the volume of this prism is 85.
Have a nice day and mark brainliest if possible - it always helps ;)
