Answer:

75.36 feet of edging material

Step-by-step explanation:

The formula to calculate the length of a circumference is:

C = 2 * pi * r

Where C is the length and r is the radius.

If the circular patio has a radius of 12 feet, we can use the formula to calculate the length of the circular patio:

C = 2 * 3.14 * 12 = 75.36 feet

It will be needed 75.36 feet of edging material.

Combine like terms to simplify the expression:<br> 1.17-0.07a+(-3.92a)
Pachacha [2.7K]

After combining like terms and simplifying 1.17-0.07a+(-3.92a) we get 1.17-3.99a

Step-by-step explanation:

We need to combine like terms to simplify the expression:

1.17-0.07a+(-3.92a)

Like terms: The terms are like when they have same variable and same exponent.

Solving:

1.17-0.07a+(-3.92a)\\=1.17-0.07a-3.92a\\=1.17+(-0.07a-3.92a)\\=1.17+(-3.99a)\\=1.17-3.99a

So, After combining like terms and simplifying 1.17-0.07a+(-3.92a) we get 1.17-3.99a

If $315 is invested at an interest rate of 3% per year and is compounded continuously, how much will the investment be worth in
irina [24]

Answer:

\$412.64

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

t=9\ years\\ P=\$315\\ r=0.03  

substitute in the formula above  

A=\$315(e)^{0.03*9}=\$412.64
