A timer is started and a few moments later a swimmer dives into the water and then comes back up. The swimmer’s depth (in feet)

as a function of time (in second after time was started) is given by the equation h(t)=t^2- 16t + 55
Rewrite the formula and select each true statement below.

Options:
The swimmer dives into the water 5 seconds after the timer is started.

The swimmer reaches a maximum depth of 16 feet.

The swimmer comes back up 16 second after the timer is started.

Dayson is covering a package in the shape of a rectangular prism with wrapping paper. The package is 50 centimeters by 20 centim
goblinko [34]
<span>Dayson has 1 m2 of wrapping paper, which is 10000 cm2:
 1 m = 100 cm
 1 m^2 = (100 cm)^2 
 </span>1 m^2 = 10000 cm^2
 <span>The package has a surface area of cm2:
 A = 2*(50*20) + </span>2*(50*18) + 2*(18*20)
 A = <span> <span>4520 cm^2
 </span></span>The area of the package is less than the area of the wrapping paper (4520 cm^2 < 10000 cm^2<span>). So, Dayson cover the package with the wrapping paper.</span>

All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.

a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2
