Hello!

You solve this algebraically

x^2 - 100 = 0

Add 100 to both sides

x^2 = 100

Take the square root of 100

When you take a square root the solutions are the number positive and negative

x = 10
x = -10

The answer is C. x = 10, -10

Hope this helps!

Answer:

$\Huge \boxed{-2}$

Step-by-step explanation:

$f(x)=-2x^2-2x+10$

For f(2), the input of the function is 2.

Let x = 2.

$f(2)=-2(2)^2-2(2)+10$

Evaluate.

$f(2)=-2(4)-2(2)+10$

$f(2)=-8-4+10$

$f(2)=-2$

The components of vector a⃗ are ax = + 3.90 and ay = -4.00. What is the angle measured counterclockwise from the +x-axis to vect

Genrish500 [490]

The angle is the arctangent of the ratio of ay to ax. Since ay is negative and ax is positive, it is a 4th-quadrant angle.

... arctan(ay/ax) = arctan(-4.00/3.90) ≈ 314.27°

... about 5.48513 radians
