The equation y 16t 2 18t 405 describes the height in feet of a ball thrown downward at 18 feet per second from a height of 405 f
kumpel [21]

Answer:

Ball hits the ground after 4.5 sec

Step-by-step explanation:

Let a -1, so that the leading coefficient is positive

So our quadratic is

-1 \times (16t^2 +18t -405)

The key coefficients of two binomial variables can be 1 and 16, or 2 and 8, or 4 and 4, for the leading coefficient of 16.

Yet they can't actually be 4 and 4 because the linear (x) term coefficient has to be a multiple of 4, which it isn't and leading coefficients 1 and 16 on the binomial factors is not likely.

So, 2 and 8 taken as the leading coefficients of  two binomial factors.

For constant  405, possible factorizations are (81\times 5, 27 \times 15, 9 \times 45).

(16t^2 +18t -405) = (8t + 45) (2t - 9)

Taking first factor, thus we find  negative value for given time t. But  second time equivalent to zero gives the value of 4.5 for t

Thus ball hits the ground after 4.5 sec

If g(x)=f(x)−1, then g(x) translates the function f(x) 1 unit _[blank]_. Which word correctly fills in the blank in the previous
Nataly [62]

Answer:

Down

Step-by-step explanation:

Given

g(x) = f(x) - 1

Required

The translation of f(x) that gives g(x)

Given that the relationship between 2 functions be:

g(x) = f(x) - b

This means that f(x) is translated b units downward to give g(x). <em>So, the word that completes the blank is down</em>
