G(n) = 2n^2 - 4n; Find g(-9)

Mathematics
1 answer:
rusak2 [61]2 years ago
6 0

Answer:

g(n) = 2n^2 - 4n; Find g(-9)

The answer is 170, because you have to plug in -9 for all the N values. When you do that, just follow PEMDAS.

P-Parentheses

E-Exponents

M-Multiplication

D-Division

A-Addition

S-Subtraction

Step-by-step explanation:

g(-9) = 2(-9)^2 - 4(-9)

g(-9) = 18^2 -4(-9)

g(-9) = 134+36

g(-9) = 170

I really hope this helps!

Sincerely,

Do supplementary angles form right angles? yes or no
Anuta_ua [19.1K]

Answer:

Yes i

Step-by-step explanation:

A supplementary angle can be two angles that sum up to 180 if you want you can have 2 angles that are 90 degrees that add up to 180 so therefore that would make a right angle.

I need help finding if it’s either SOH, CAH or TOA and the indicated side of the triangle, thank you!
Brilliant_brown [7]

Answer:

\huge\boxed{IJ \approx 2.01}

Step-by-step explanation:

In order to find the side mentioned (IJ), we need to use SOH CAH TOA.

SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:

Sin = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tan = Opposite / Adjacent

Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.

Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.

Our equation is now this: \text{sin(42)} = \frac{x}{3}

Let's now solve for x.

  • \text{sin(42)} = \frac{x}{3}
  • 3 \cdot \text{sin(42)} = x
  • \text{sin(42)} \approx 0.67
  • 3 \cdot 0.67 \approx 2.01

Therefore, the length of IJ will be around 2.01.

Hope this helped!
