ok we have given three function h(x) defined in certain limits.for the first function

x≤-2 and second function -2<x≤-2 and for third function x>2

to find h(-1) we have the limit -2<x≤-2 so we need to plug -1 in the function -(x+1)²+2= -(-1+1)²+2=0+2=2.

to find h(-2) we know that we have x≤-2 so we need to plug x=-2 in tghe equation (1/4)x+2=(1/4)(-2)+2=-1/2+2=3/4.

for h(0) we know that zero lies in the limit -2<x≤2 so we need to plug x=0 in equation -(x+1)²+2=-(0+1)²+2=-(1)+2=1.

_ABC is a right triangle where m_B = 90Á. The coordinates of A and B are (5, 0) and (2, 5), respectively. If the x-coordinate of
Leokris [45]
Since the triangle is a right triangle at point B, then line AB is perpendicular to line BC.
For perpendicular lines, the product of their slopes is -1.
Slope of AB = (5 - 0)/(2 - 5) = 5/-3 = -5/3
Slope of BC = (y - 5)/(7 - 2) = (y - 5)/5

-5/3(y - 5)/5 = -1
-5(y - 5)/15 = -1
-5(y - 5) = -15
y - 5 = 3
y = 3 + 5 = 8

Therefore, the y-coordinate of point C is 8.

!!!URGENT!!! Read Image Below.
KIM [24]

Answer:

x = \frac{6 \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}

Step-by-step explanation:

Given the equation, 3x^2 - 6x + 8 = 0, the quadratic formula for solving this equation is given as:

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Where,

a = 3

b = -6

c = 8

Plug in the above values into the quadratic formula.

x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}

x = \frac{6 \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}

The formula for the volume of a sphere is V=4/3πr³, where V is the volume and r is the radius. Solve the formula for r, and then
3241004551 [841]

Answer:

4.5 inches to the nearest tenth

Step-by-step explanation:

V=4/3πr^3

Divide both sides by 4/3π:

r^3 =  V / 4/3π

r =  ∛ (V / 4/3 π)

When V = 371 inches:

r =  ∛ (371/ 4/3 π)

= 4.46 in
