Answer:
cos W = 7/15
Step-by-step explanation:
Mathematically the cosine of an angle is the ratio of the adjacent to the hypotenuse side
From the diagram given, 14 is adjacent to vertex w and 30 faces the right angle which makes it the hypotenuse
So, we have it that;
cos W = 14/30
cos W = 7/15
Answer:
x = 3.464
Step-by-step explanation:
7x^2 - 84 = 0
7x^2 = 84
x^2 = 12
x= 3.464
Factor by grouping.
(7x+2)(x-2) I think not sure
Answer:
A = 16010.32
Step-by-step explanation:
Given that,

Put P = 10,000, r = 0.08, k = 2 and n = 12 in the above formula to find A.

So, the value of A is 16010.32. Hence, the correct option is (B).
