Step-by-step explanation:

The formula for the computation of simple interest is ...

... I = Prt

where I is the interest amount, P is the principal amount, r is the rate, and t is the number of years.

Fill in the given numbers and solve for t.

... 5704 = 15500×0.046×t

... 5704/713 = t = 8 . . . . . . divide by the coefficient of t

It takes 8 years to earn $5704 on that investment at 4.6% per year.

Terry invested money in a biotech stock whose growth is modeled by the function f(x) = 0.01(2)x, where x represents number of da
strojnjashka [21]

Answer:

The average rate of change is 1.275

Step-by-step explanation:

The average rate of change of f(x) from x=a to x=b is given by:

\frac{f(b)-f(a)}{b-a}

The money Terry invested is modeled by the function f(x)=0.01(2)^x where x represents number of days.

The average rate of change from day 2 to day 10 is given by:

\frac{f(10)-f(2)}{10-2}

f(10)=0.01(2)^{10}=10.24

f(2)=0.01(2)^{2}=0.04

The average rate of change becomes:

\frac{10.24-0.04}{8}

=\frac{10.2}{8}=1.275

A petrol can is a rectangular prism with base measurements 15 cm by 30 cm. If the can has capacity 18 liters, find its height.​
Bingel [31]

Answer:

40

Step-by-step explanation:

The first step is to calculate the base area of the prism

= 15×30

= 450

The volume is then calculated as follows

= 450×h

= 450h

The capacity is 18 liters

= 18×1000

= 18,000

Therefore the height of the rectangular prism can be calculated as follows

450h= 18,000

h= 18,000/450

= 40

Hence the height is 40 cm
