Which of the following pairs lies on the graph of h(x) = -2x(x to the second power)? 1, -4
1, -2
1, 4

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

she will travel a distance in the range of 3 - 11 miles
