Answer:
cos Θ = 7/25
Step-by-step explanation:
First, we find the hypotenuse.
c² = a² + b²
c² = 7² + 24²
c² = 49 + 576
c² = 625
c = √625
c = 25
cos Θ = adj/opp
cos Θ = 7/25
Answer:
n=80
Step-by-step explanation:
n+75=155
Take away 75 by doing -75 to level it out.
Then you have n = 80.
Answer:
Step-by-step explanation:
A quick review on PEMDAS, the order of how to solve an equation:
P - parentheses. When parentheses are being used, you have to do everything inside them before doing everything outside of them.
E - exponents. We'll skip these, since there aren't any exponents we need to worry about in this equation.
M/D - multiplication/division. I include these both together because they can be done at the same time.
A/S = addition/subtraction. Can also be done at the same time.
Some other things to note:
You add all the things with an x attached to it, and you add all the things without an x attached to it, and these never cross.
When you bring something from one side of an equal sign to another, you make it negative.
Let's solve for x using what we've learned:
Answer:
(gºf)(0) = 16
Step-by-step explanation:
Given,
f(x) = -3x + 4
g(x) =
Now,
(g°f)(x) = g(f(x))
thus, (g°f)(0) = g(f(0))
= g(4) As, f(x) = -3x + 4
f(0) = -3(0) + 4 = 4.
= As,
g(x) = x²
= 16.
Thus , (gºf)(0) = 16
