a/b The decay can be modeled by this equation, (1 - r), the r being the rate of decay. So it would be 1-0.115. (0.115 is your answer for a) You have to convert the percent into a decimal by moving the deicmal place two places to the left. 0.885 is your answer for b.

c. For function notation, that just means write an equation. So you want your decay times your inital. V(t)=15000(0.885)^x. We get the V(t) from the directions that they want us to put it in; it's basically y.

d. Since it's two years, plug in 2 for x. This shows the decay after two years

V(t)=15000(0.885)^2

e. As with d, plug in 10 for x. V(t)=15000(0.885)^t

lina2011 [118]

Answer:

x is the number of large boxes shipped

y is the number of small boxes shipped

7 large boxes were shipped

14 small boxes were shipped

Step-by-step explanation:

The volume of each small box is 6 cubic feet and the volume of each large box is 12 cubic feet.

There were twice as many small boxes shipped as large boxes shipped : so if x large boxes , and y small boxes were shipped, then ,y = 2x small boxes were also shipped.

the total volume of all boxes was 168 cubic feet, which means:

y = 2x ...................(1)

6y + 12x = 168 .......(2),

then, replace y to 2x in the second equation

6(2x) + 12(x) = 168,

12x + 12x = 168,

24x = 168,

x = $\frac{168}{24}$ = 7,

since the small boxes = 2x,

2(7) = 14 boxes, so there are 14 small boxes being shipped,

and x = 7, so there are 7 large boxes being shipped, since x is the number of large boxes being shipped.

madam [21]

4 yrs

Step-by-step explanation:

Formulae for simple interest is;

A= P (1 + rt) Whereby;

A = Total Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

r = Rate of Interest per year in decimal; r = R/100

R = Rate of Interest per year as a percent; R = r * 100

t = Time Period involved in months or years

15300 = 3200 (1 + 106.5/100 *t)

15300/3200 = 1 + 1.065t

4.78125 – 1 = 1.065t

3.78125 = 1.065t

3.78125/1.065 = t

3.55 = t

Rounded off to the nearest whole number;

= 4
