Soon after taking an aspirin, a patient has absorbed 320 mg of the drug. after 3 hours, only 40 mg remain. find an exponential m

Anastaziya [24]

The equation will be of the form:
$A(t)= A_{0} e^{rt}$
where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:
$40=320e^{3r}$
Rearranging and taking natural logs of both sides, we get:
$ln\ 0.125=3r$
$r=\frac{ln\ 0.125}{3}=-0.693$
The required model is:
$A=A _{0} e^{-0.693t}$

isabella is covering a square tabletop with square mossaic tiles.the tabletop is 2ft. long and 2ft.wide.each tile is 1/4 in.long

Hunter-Best [27]

Convert the feet to inches first. 2 ft = 24 inches. We must divide this total length by the length of each tile to determine how many tiles will fit across the tabletop:

24 ÷ (1/4) = (24/1) ÷ (1/4) = (24/1) × (4/1) = 96/1 = 96

96 tiles will fit across the tabletop.
Since the tabletop is as long as it is wide, that means we will have 96 rows of 96 tiles:
96(96) = 9,216 tiles to cover the tabletop.

Please help! The length of a rectangle is 3 less than 4 times the width. The perimeter is 34. Find the length and width of the r

Inga [223]

Length (L): 4w - 3

width (w): w

Perimeter (P) = 2L + 2w

34 = 2(4w - 3) + 2(w)

34 = 8w - 6 + 2w

34 = 10w - 6

40 = 10w

4 = w

Length (L): 4w - 3 = 4(4) - 3 = 16 - 3 = 13

Answer: width=4, length = 13
