A diving board is 10 feet above the surface of the water. At time t = 0, the board propels Chris upward at a rate of 12 feet per

Art [367]

Answer:

Chris will take 0.75 seconds to return to his starting height of 10 feet.

Step-by-step explanation:

Let the height of Chris be represented by $h(t) = -16\cdot t^{2}+12\cdot t +10$ , where $h(t)$ is the height in feet and $t$ , the time in seconds. First, we equalize the formula to a height of 10 feet and simplify the resulting expression, that is:

$-16\cdot t^{2}+12\cdot t +10 = 10$

$-16\cdot t^{2}+12\cdot t = 0$

Then, we simplify the expression by algebraic means:

$-16\cdot t\cdot \left(t-\frac{3}{4} \right) = 0$

Roots of the polynomial are, respectively:

$t = 0\,s\,\lor \,t = 0.75\,s$

First root represents the initial height of Chris, whereas the second one represents the instant when Christ returns to the same height above the surface of the water. Hence, Chris will take 0.75 seconds to return to his starting height of 10 feet.

Eric's apartment is 1350 s1quare feet, how many square meters of carpet will he need to order?

ArbitrLikvidat [17]

Answer:

He needs to order $125.42\ m^{2}$ of carpet

Step-by-step explanation:

we know that

$1\ ft=0.3048\ m$

we have

$1,350\ ft^{2}$

Convert to $m^{2}$

$1,350\ ft^{2}=1,350(0.3048)^{2}=125.42\ m^{2}$

3. If Earth was 10 times farther away from the sun than it is now, which planet would it be closest to? (Assume all the planets

Valentin [98]

Real distance of Earth from Sun . . . 93 million miles
= 1 AU (Astronomical Unit)

10 times farther . . . . . 930 million miles = 10 AU

Compare:

==> Saturn . . . 9.5 AU
==> Uranus. . 19.2 AU

If Earth were 10 times farther from the sun than we really are,
then our planet would be just barely past Saturn ... about 10%
of the way from Saturn to Uranus.
