Studies show that a typical giant hummingbird can flap its wings once in 0.08 of a second.
a. while flying for 7.2 seconds, how many times will a typical giant hummingbird flap its wings?
b. a ruby-throated hummingbird can flap its wings 4 times faster than a giant hummingbird. how many times will a ruby-throated hummingbird flap its wings in the same amount of time?

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 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 times = 360 times

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
