10 POINTS WILL MARK BRAINLIEST Find the restriction on y=2x^2-8

borishaifa [10]

X cannot equal +2, and can't be -1. If you factor it, then you notice you get 2(x+2)(x-2). If you use either one for the x, one will be zero and the won't, and vise-versa.

How much greater is the surface area of the cube?

Soloha48 [4]

The surface area 3 times greater than the area.

6 * 2 gives the area
the surface area is by multiplying area by 3.
this means that the surface area is 3x bigger than area.

Hey there!

When two lines intersect, the pairs of angles that are directly across from each other (ex. the pair depicted in the image) are called opposite angles. These angles always measure the same.

This means that we can set the two expressions equal to each other and solve for x:

2x + 2 = 3x - 52

x = 54

Hope this helps!

Derivative Notation
The derivative of a constant is equal to 0
Derivative Property: $\frac{d}{dx} [cf(x)] = c \cdot f'(x)$
Trig Derivative: $\frac{d}{dx} [cos(x)] = -sin(x)$

Step-by-step explanation:

Step 1: Define

g(x) = 8 - 10cos(x)

x = 0

Step 2: Differentiate

Differentiate [Trig]: g'(x) = 0 - 10[-sin(x)]
Simplify Derivative: g'(x) = 10sin(x)

Step 3: Evaluate

Substitute in x: g'(0) = 10sin(0)
Evaluate Trig: g'(0) = 10(0)
Multiply: g'(0) = 0
