you miss something, maybe log is lg.
Answer:
Step-by-step explanation:
Yes
{1,3,5,7} contains the first 4 odd numbers.
{1,2,3,5,7} would not be a subset.
Applying the cosine ratio, the measure of angle C in the given image, to the nearest whole degree, is: 77°.
<h3>What is the Cosine Ratio?</h3>
The cosine ratio is given as, cos ∅ = adjacent side/hypotenuse side of a right triangle.
Using the cosine ratio, we have:
cos C = 2/9
C = cos^(-1)(2/9)
C ≈ 77 degrees.

Answer:
4^4
Step-by-step explanation:
Since there are four 4's, it is to the 4th power.
A(x - x₁)(x - x₂) = 0
a=5, x₁=-3, x₂ = 3
so:
5(x-(-3))(x-3)=0
5(x+3)(x-3)=0
5(x²-9) = 0
5x² - 45 = 0 ← answer
