The function f(x) is a quadratic function and the zeros of f(x) are 3 and 4. Assume the leading coefficient of f(x) is 1. Write the equation of the quadratic polynomial in
standard form.

y=x²-7x+12

Step-by-step explanation:

Since the zeroes are 3 and 4, those are also the x-intercepts. That means that the two factors would be (x-3) and (x-4).

Basic factored form is y=a(x-zero) (x-zero). In your case, it would start as:

y=1(x-3)(x-4)

Standard form is when it's multiplied out and in the form:

y=ax²+bx+c. so you need to multiply the factored form or completely.

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°
