the question is incomplete, the complete question is
"Finding Derivatives Implicity In Exercise,Find dy/dx implicity . 
"
Answer : 
Step-by-step explanation:
From the expression " y is define as an implicit function of x, hence we differentiate each term of the equation with respect to x.
we arrive at
for the expression 
we differentiate using the product rule, also since y^2 is a function of y which itself is a function of x, we have
.
if we make dy/dx subject of formula we arrive at
Answer:
36
Step-by-step explanation:
The maximum height is the y-coordinate of the vertex
given a quadratic in standard form : ax² + bx + c : a ≠ 0
then the x-coordinate of the vertex is
= - 
y = - x² + 20x - 64 is in standard form
with a = - 1, b = 20 and c = - 64, hence
= - 
= 10
substitute x = 10 into the equation for y
y = - (10)² + 20(10) - 64 = 36 ← max height
Answer: i think 2 feet, not really sure tho ':)
Step-by-step explanation:
Answer:
-11 - 13i.
Step-by-step explanation:
(12) — (23 + 13i)
= 12 - 23 - 13i
= -11 - 13i.
5x^2 -15x-140
5(x² -(3x) -28)
5(x² +(4x-7x)-28)
5(x(x+4) -7(x+4)
5(x-7)*(x-4)
