We are asked to find the principal value of
cos ⁻¹ (0.69)
which is just the least positive angle
cos ⁻¹ (0.69) = 46.37°
Other values of
cos ⁻¹ (0.69) is
46.37° - 180° n
where n is a whole number
You will take 100 = 15.5x - 7 and solve.
the end product comes out to be 6 = x or (OCD is kicking) x = 6.
hope this helps (; hmu if u need more info
Answer:
D) commutative property of addition
You can find an equivalent expression for this by combining like terms.
The terms are 88, 16x, and 8.
The like terms are 88 and 8.
To combine them, add them together.
88 + 8 = 96
The equivalent expression would be 16x + 96.
This means 16x + 96 is the same as <span>88 + 16x + 8.
Since they are equivalent, that means they are equal, or the same.
So no matter what x is, they will both be equal to the same thing, so their solutions will be the same.
Answers:
Equivalent Expression: 16x + 96
Yes, both expressions will have the same solutions if x = 4.
Hope this helps!</span>
