Mr. Carlevato and Mr. Burrows get into a debate about two different expressions. · Mr. Carlevato says "2(2x + 3) is equal to 4x

ruslelena [56]

Answer:

Yes, the same answer is obtained.

Step-by-step explanation:

According to Mr. Carlevato, $2(2x+3)$ is equal to $4x+6$ . However, $2(2x+3)$ is not equal to $4x+6$ according to Mr. Burrows.

Put $x=5$ in $2(2x+3)$

$2[2(5)+3]=2(10+3)=2(13)=26$

Put $x=5$ in $4x+6$

$4x+6=4(5)+6=20+6=26$

Therefore,

$2(2x+3)=4x+6$

Yes, the same answer is obtained.

Answer: 82.26 yd^2

Step-by-step explanation:

Solve this question in steps.

Find the area of the rectangle.

9x6=54

Now, find the area of the circle.

The diameter is 6 so the radius must be 3.

3^2xpi=9pi=28.26

Add the values together.

54+28.26=82.26

Sarah invests her graduation money of $1.750 in an annuity that pays an

Stels [109]

We have been given that Sarah invests her graduation money of $1,750 in an annuity that pays an interest rate of 6% compounded annually. We are asked to write an exponential function for her investment growth.

We will use compound interest formula to solve our given problem.

$A=P(1+\frac{r}{n})^{nt}$ , where

A = Final amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

n = Number of times interest is compounded per year,

t = Time in years.

$6\%=\frac{6}{100}=0.06$

Since interest is compounded annually, so $n=1$ .

$f(t)=1750(1+\frac{0.06}{1})^{1\cdot t}$

$f(t)=1750(1+0.06)^{ t}$

$f(t)=1750(1.06)^{ t}$

Therefore, the function $f(t)=1750(1.06)^{ t}$ describes Sarah's investment growth.
