What is the graph of y=-(x-2)^3-5

natulia [17]

When x=0,
y=-(0-2)^3-5
y=3

When y=0,
(x-2)^3=5
x-2= +/- 5^1/3
x= +/- 5^1/3 +2
x= 3.70997 or x=0.29002

To find the turning point at y, substitute the information that you have found above.

y=-(3.70997-2)^3-5
y=-9.99994

Find the mid-point next as mid-point is also the turning point.

(3.70997+0.29002)÷2=1.999995

Hence, Turning point is (1.999995, 9.99994)

Plot a graph using turning point, y value and the 2-x values.

A circle is divided into three arcs of measures x 2x and 3x what’s the value of x

lidiya [134]

Answer:

60°

Step-by-step explanation:

This questions tests our knowledge on arcs and arc measures.

-Arc measure is the angle that an arc makes with the circle's center.

-The arc measure is proportional to the arc.

#The sum of the 3 arcs is x+2x+3x=6x

Given a circle has 360°, the arc measurement x can be calculated as:

$[x+2x+3x]=360\textdegree\\\\6x=360\textdegree\\\\x=60\textdegree$

Hence, the arc measurement x is 60°

What is the surface area of a cylinder with a base radius of 3 ft and a height of 5ft

Solnce55 [7]

SA of a cylinder: 2 $\pi$ r² + 2 $\pi$ rh
r = radius of base
h = height of cylinder

Plug in 3 for r and 5 for h in the formula.
2 $\pi$ 3² + 2 $\pi$ (3)(5)
Use a calculator to solve.

2 $\pi$ 3² + 2 $\pi$ (3)(5) = 150.8 ft²
