Based on our conversation above, we can then easily find the missing x-coordinate. If the equation for line BC is y = 6*x - 11 and we know that the y-coordinate is 13, then

13 = 6*x - 11
24 = 6*x
4 = x

The x-coordinate is 4.

Studies show that a typical giant hummingbird can flap its wings once in 0.08 of a second.
Licemer1 [7]

Answer:

a. 90

b. 360

Step-by-step explanation:

The time taken by humming bird to flap its wings= 0.08 sec

by flying 7.2 seconds a typical giant hummingbird flap its wings \frac{7.2}{0.08} times

= 90 times

Since, A ruby-throated hummingbird can flap its wings 4 times faster than a giant hummingbird, it will flap its wings in every 0.02 sec

so in 7.2 seconds it will flap \frac{7.2}{0.02} times = 360 times

F(1)=−2<br> f(2)=5<br> f(n)=f(n−2)⋅f(n−1)<br> f(3) = ?
3241004551 [841]
<h3>Answer:  -10</h3>

Work Shown:

f(n) = f(n-2)*f(n-1)

f(3) = f(3-2)*f(3-1)

f(3) = f(1)*f(2)

f(3) = -2*5

f(3) = -10
