Answer:
The answer is option B
Step-by-step explanation:
To find cos 45° we must first find the adjacent and the hypotenuse
Let the adjacent be x
Let the hypotenuse be h
To find the adjacent we use tan
tan ∅ = opposite / adjacent
From the question
the opposite is 9
So we have
tan 45 = 9 / x
x tan 45 = 9
but tan 45 = 1
x = 9
Since we have the adjacent we use Pythagoras theorem to find the hypotenuse
That's
h² = 9² + 9²
h² = 81 + 81
h² = 162
h = √162
h = 9√2
Now use the formula for cosine
cos∅ = adjacent / hypotenuse
The adjacent is 9
The hypotenuse is 9√2
So we have
cos 45 = 9/9√2
We have the final answer as
<h3 /><h3>cos 45 = 1 / √2</h3>

Answer:
you should check your phone
Step-by-step explanation:
you should because what if the phone call was super important? When you are with your friends try saying"I have to use the bathroom" or something else and go pick up the phone in the bathroom.If you pick up the phone in front of them they will think that you don't want to hang out.

Answer:
t = 0
If the loan is to be paid in 0 months, the amount is very large
m = 50
Of the loan is to be paid in an indefinite amount of time, monthly payment would be 50
Step-by-step explanation:
(12000 + 600t)/12t
1000/t + 50
Asymptotes:
t = 0
If the loan is to be paid in 0 months, the amount is very large
m = 50
Of the loan is to be paid in an indefinite amount of time, monthly payment would be 50
Answer:
C
Step-by-step explanation:
1/10th of 650 is 65. then, do 650 - 65. 9/10th of 650 is 585, so the answer to this question is C.
