Answer:
72 sq ft.
Step-by-step explanation:
Surface area of Triangular prism=[2*(1/2)*3*4]+(5*5)+(3*5)+(4*5)=12+25+15+20=72 sq ft.
Answer:
x = 23
Step-by-step explanation:
1/4(x-3)=5
Multiply both sides by 4.
x - 3 = 20
Add 3 to both sides.
x = 23
A unit circle has its center at the origin and has a radius of one. It is modeled by the equation
x² + y² = 1
We are given with <span>(x,-1)</span> .
Solving for x
x² + (-1)² = 1
x = 0<span />
let's put value of t in equation.
x = 2√t
x = 2√y
x/2 = √y
(x/2)^2 = y
y = x^2 /4
now let's differentiate it with respect to x.
dy/dx = 2x/4 = x/2
differentiating again wrt to x
d^2y/dx^2 = 1/2
