<h3>Answer: C) none of the equations are identities</h3>

If you plugged theta = 0 into the first equation, then you would have

sin(45) + cos(45) = sin(0) + cos(0)

sqrt(2) = 1

which is a false equation. We don't have an identity here.

The same story happens with the second equation. Plug in theta = 0 and it becomes

cos(60) - sin(60) = cos^2(0) + tan(0)

1/2 - sqrt(3)/2 = 1 + 0

-0.37 = 1

which is false.

Given<br> f(x) = 3x + 10 and g(x) = x - 2, find f (g(5))<br> -10<br> 23<br> None of these.
azamat
Answer: None of these

Explanation:

f(g(5)) first let’s find g(5)

We know:
g(x) = x - 2
g(5) = 5 - 2
g(5) = 3

Thus, f(g(5)) = f(3) because g(5) = 3

=> f(3) = 3(3) + 10
=> f(3) = 9 + 10
=> f(3) = 19

Therefore, f(g(5)) = 19

12 times a number decreased by 5 is no more than 55
lions [1.4K]

Answer:

  12n -5 ≤ 55

Step-by-step explanation:

12 times a number (represented by n) is 12n.

"Decreased by 5" means 5 is subtracted from the product, giving 12n-5.

"Is no more than 55" means "is less than or equal to 55".

Then the expression written using math symbols is ...

  12n -5 ≤ 55
