3 * 5=15
15-8=7
so 3 times what equal what , so the current number you have u subtract that number to the number you need it to equal

Are you trying to graph it?

First you should get it to the main equation slope intercept form which is y=mx + b

3x-y=7
-y= -3x + 7
y=3x -7

The standard way for the slope intercept form is Ax+ By= C
3x -y=7

I'm not sure if I am doing this correctly but I hope this sort of helps

Hello,

If you know the ration (i don't)
a(4)=a(3)*r=a(2)*r²=a(1)*r^3
==>a(4)=15*r^3

What is the total investment of $2150 invested at 5.3% for 16 years and compounded continuously?

sladkih [1.3K]

Answer:

The total investment is $5020.19

Step-by-step explanation:

Given : $2150 invested at 5.3% for 16 years and compounded continuously

To find : What is the total investment?

Solution :

The formula of continuously compounded interest is

$A = Pe^{rt}$

Where A = amount invested

P = principal = $2150

e = Euler's number (on calculator)

r = interest rate as decimal = 5.3%=0.053

t = time in years = 16 years

Substitute the value in the formula,

$A = Pe^{rt}$

$A = 2150\times e^{0.053\times 16}$

$A = 2150\times e^{0.848}$

$A = 2150\times 2.3349$

$A = 5020.19$

Therefore, Option 4 is correct.

The total investment is $5020.19.

A circle has a circumference of 34 54 cm. What is the area of the circle to the nearest whole centimeter? Use 3.14

inysia [295]

Answer:

Step-by-step explanation:

We know that the Circumference = 3454 cm

And we also know that the formula for the Circumference of Circle is,

$2\pi \times r$

So we can put the equation this way,

$3454 = 2\pi \times r$

So we can solve for 'r'

$3454 = 2 \times 3.14 \times r \\ 3454 = 6.28r \\ r = \frac{3454}{6.28} \\ r = 550$

Now we have radius and we can solve for the area of the circle,

$\pi \times {r}^{2}$

$3.14 \times 550 \times 550 \\ = 949850$

We can convert this to meter,

9498.5 m

I am not sure if this is correct just let me know thanks :)

If you wish to calculate the interest on an investment with a rate of 3.58%, what number will you plug into your equation?

irina [24]

To get a certain percentage as a decimal, all you have to do is divide this percentage by 100.

Applying this on the given question, we will find that:
3.58% = (3.58) / (100) = 0.0358

Comparing the calculated value to the given choices, we will find that the correct choice is:
