A toy car launched into the air has a height (h feet) at any given time (t second) as h= -16t + 160t until it hits the ground. A

ivanzaharov [21]

Answer:

$t_{1} \approx 9.943\,s$ and $t_{2} \approx 0.057\,s$

Step-by-step explanation:

The following polynomial is needed to be solved:

$-16\cdot t^{2} + 160\cdot t - 9 = 0$

The roots are found by means of the General Equation for Second-Order Polynomials:

$t_{1} \approx 9.943\,s$ and $t_{2} \approx 0.057\,s$

Physically speaking, both solutions are reasonable.

The function g is related to one of the parent functions g(x) = |x − 1| + 5 a.) Identify the parent function f.

pogonyaev

Based on the graph, we can see that the x and y values of g(x) will never be negative. They also show an increasing curve that resembles the graph of a square root function. Hence, the parent function of g(x) is y = √x
