Answer:
A
Step-by-step explanation:
Think about the square root of 64, which is 8. It will only be slightly higher than 8, which will not even be .5, so 8 is the closest number.
Answer:
21 ft
Step-by-step explanation:
C = 2πr
Filling in the given values, we have ...
131.88 ft = 2·3.14·r . . . . we can find r by dividing by its coefficient
131.88 ft/6.28 = r = 21 ft
Answer:
B) 0.85
Step-by-step explanation:
By definition, complementary angles add to 90 degrees.
The given angle 58 degrees is complementary to 90-58 = 32 degrees. The two angles 58 and 32 add to 90.
Therefore, cos(32) = 0.848 = 0.85
OK.
Let g(x) = ax²
We have the point (3, 1).
Substitute x = 3 and g(x) = 1:
1 = a(3²)
9a = 1 |divide both sides by 9
a = 1/9
Therefore your answer is
