With functions, you take the number that is in the ( ), so we have f(-2), and take the fomula f(x) = 0.8(2 – x) and everywhere you see an 'x' replace it with the -2 f(–2)=0.8(2 – (-2))
We will have to work with the expression of 0.8(2-(-2) When you want to evaluate these types of expressions, you want to use the Order of Operations: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. First we have to evaluate the parentheses. What is 2-(-2)
its 4.
ok now you got 0.8 (4)
Now we have the remains of 0.8(4). If a number is within the parenthesis, then it means that we have to multiply the number inside with the number that is outside. What is 0.8*4 its 3.2 soooo your answer is going to be
3.2
parallel means "same slope (m)"
m =
= ![\frac{0 - 5}{-3 - (-6)} = \frac{-5}{-3 + 6} = \frac{-5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B0%20-%205%7D%7B-3%20-%20%28-6%29%7D%20%3D%20%5Cfrac%7B-5%7D%7B-3%20%2B%206%7D%20%3D%20%5Cfrac%7B-5%7D%7B3%7D)
Now, input the point (0, 0) and the slope
into the Point-Slope formula:
y - y₁ = m(x - x₁)
y - 0 =
(x - 0)
y = ![\frac{-5}{3}x](https://tex.z-dn.net/?f=%5Cfrac%7B-5%7D%7B3%7Dx)
3y = -5x <em>multiplied both sides by 3</em>
0 = -5x - 3y <em>subtracted 3y from both sides</em>
Answer: C
Answer:
4.62
Step-by-step explanation:
using the distance formula plug in the 6
6=-8cos(pi/6 t)
Answer:
15/17
Step-by-step explanation:
Sine is
, and we see that the angle opposite of A is 15 while the hypotenuse is 17. Plug that into your formula and you get
.
The equation is base area x height so is 11/4 x 4 x 3 1/4 = 35.75
