The three geometric means between 3 and 512 are…
8, 32, 128
OR
-8, 32, -128
The first choice is your answer. Since it’s substitution, you have to plug in x to the x in the bottom equation
Answer:
9 to the 7th power
Step-by-step explanation:
Answer: The distance between the birds is about 77.78 yards.
This is a trigonometry problems, so it helps to draw a right triangle between the birds. The length between them is the hypotenuse and we have a angle of 40 degrees by the sparrow. The side opposite the sparrow is the difference in heights of the birds, 50 yards.
Therefore, we can write and solve the following sine relationship.
sin(40) = 50/x
0.6428 = 50/x
x = 77.78 <span />
