Scilla [17]

Answer:

$\textsf {55 miles}$

Step-by-step explanation:

$\textsf {Company A}$

$\textsf {Fee = 88}$

$\textsf {Mileage = unlimited (0 charged)}$

$\textsf {Equation = 88 (Statement 1)}$

$\textsf {Company B}$

$\textsf {Fee = 55}$

$\textsf {Mileage = 0.60 per mile}$

$\textsf {Equation = 55 + 0.60m (Statement 2)}$

$\textsf {Now, the inequality will be :}$

$\mathsf {88 < 55 + 0.60m}$

$\mathsf {0.60m > 33}$

$\mathsf {m > \frac{33}{0.60} }$

$\mathsf {m > 55}$

Hence, for Company A will charge less than Company B when the mileage is greater than 55 miles.

Suppose an object is dropped from a height h0 above the ground. Then its height after t seconds is given by h = −16t 2 + h0, whe

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

Given

$h=-16t^2+h_0$

ball is dropped from a height of $59 ft$

therefore $h_0=59 ft$

$h=-16t^2+59$

Time taken to fall half the distance to the ground level i.e. $h=\frac{59}{2}$

$\frac{59}{2}=-16t^2+59$

arranging we get

$16t^2=\frac{59}{2}$

$t^2=\frac{59}{2\times 16}$

$t=1.35 s$

(b)Time taken to fall

i.e. h=0

$0=-16t^2+59$

$16t^2=59$

$t^2=\frac{59}{16}$

$t=1.92 s$
