We know that cos A = 0.34.
We have to find the measure of ∠ A in degrees ( and to round it to the nearest hundredth ):
∠ A = cos^(-1) 0.34 = 70.12313° ≈ 70.12°
Proof: cos 70.12° ≈ 0.34
Answer:
∠ A = 70.12°
Answer:
J
Step-by-step explanation:
Find the common ratio r of the geometric sequence then multiply a term by r to obtain the next term
r =
=
= - ![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
The next 3 terms are
× -
= - ![\frac{1}{36}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B36%7D)
-
× -
= ![\frac{1}{216}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B216%7D)
× -
= - ![\frac{1}{1296}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B1296%7D)
Ratios can be written in 3 ways :
a to b
a/b
a:b
so ur ratio 6 to 7 can be written as 6/7 or 6:7
The regular rules of arithmetic apply to function values. Addition and multiplication are commutative, but subtraction and division are not.
The ring operator, signifying a function of a function, is not commutative, either. A simple example can illustrate this:
f(x) = 3
g(x) = x²
(f◦g)(x) = f(g(x)) = f(x²) = 3
(g◦f)(x) = g(f(x)) = g(3) = 3² = 9 . . . . . not equal to 3
The only appropriate choice for Question 19 is ...
A. (f+g)(x) = (g+f)(x)
