If the side are increased by 45% then the area of green part will be 26.6955 mm^{2}.

Given that area of a shape of 37 mm^{2} in which 60% is green.

We are required to find the area of green region if the side is increased by 45%.

Area is basically part of a surface covered by a shape.

When the side is increased by 45% then the area will increase by 45%*45%=20.25%.

Increased area =37*20.25%=7.4925

New area=37+7.4925

=44.4925

We have been given that 60% is the area of green.

Area of green region=44.4925*60/100

=26.6955 mm^{2}

Hence if the sides are increased by 45% then the area of green part will be 26.6955 mm^{2}.

Jackie makes an $800 deposit into a bank account earning 4.5% interest.
Pepsi [2]

Answer:

a. $1251.5

b. $1254.64

c. 15.4 years

d. 30.56 years

Step-by-step explanation:

Given the information:

  • Principle (P) = $800
  • Interest = 4.5%

As we know, the formula to find the future value of Jackie deposit with interest is compounded monthly, quaterly, ..is

A=P(1+\frac{r}{n} )^{nt}  where:

  • P = initial balance
  • r = interest rate (decimal)  
  • n = number of times compounded annually
  • t = time

Hence:

a. If the interest is compounded quarterly how much money will Jackie have in 10 years?

A=P(1+\frac{r}{n} )^{nt}  

<=>  A=800(1+\frac{0.045}{4} )^{4*10}

<=> A = $1251.5

d. If Jackie's money is compounded monthly, how long will it take her money to triple?

<=> A=P(1+\frac{r}{n} )^{nt} = 3*800

<=> 800(1+\frac{0.045}{12} )^{12*t} = 2400

<=> (1+\frac{0.045}{12} )^{12*t} = 3

<=> t = 30.56 years

As we know, the formula to find the future value of Jackie deposit with interest is compounded continuously

A = P*e^{rt} where e is the mathematical constant approximated as 2.7183.

b. If the interest is compounded continuously how much money will Jackie have in 10 years?

<=> A = 800*2.7183^{0.045*10}

<=> A = $1254.64

C. If Jackie's money is compounded continuously, how long will it take her money to double?

<=> P*e^{rt}  = 2*800

<=> 800*2.7183^{0.045*t} = 1600

<=> 2.7183^{0.045*t} = 2

<=> t = 15.4 years
