You invest $2,000 in an investment that pays an annual interest rate of 7.5% with monthly compounding. How many months will it take for your investment to be worth $3,500
Answer:
10 years
step-by-step explanation:
First, divide 7.5 by 100, you should get 0.075, then multiply 0.075 by 2000, you should get 150, thats how much interest he gains each year, now subtract 2000 from 3500 to see how much he needs to get to 3500, you should get 1500, now divide 1500 by 150, you should get 10, which is how many years he will need to get to 3500 from 2000
Which equation represents a circle that has a center at and a radius of 5?
what are the options?
The confidence interval based on the two-sample design is wider because there is considerable variation in mileage between the cars. The confidence interval based on the paired design is wider because there is little variation in mileage between the cars. The confidence interval based on the two-sample design is wider because there is little variation in mileage between the cars. The confidence interval based on the paired design is wider because there is considerable variation in mileage between the cars.
Answer:
The confidence interval based on the paired design is wider because there is little variation in mileage between the cars.
Step-by-step explanation:
The sample size randomly collected is matched sample and since the confidence interval is based on the paired design is large and wide. There is small variation between the mileage of the two cars indicating the cars have mileage based on the fuel.
Tessa is training for a marthon She ran 13km for 3 days how much meters did she run in all
Answer:
Tessa ran 39,000 meters in all

you invested money in two funds. last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you receive a total of $921. This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $846. How much money did you invest in each fund?
Answer:
x= $ 7100 investment in first fund
10x+y=84600 substitute the value of x
10*7100+y=84600
y=84600-71000
y= $ 13600 investment in second fund.

If an object is projected upward with an initial velocity of 125 ft per sec, its height h after t seconds is h= - 16t+ 125t. Find the height of the object after 2 seconds.
Answer:
h(t) = -16t^2+125t
We need to find h(t) when t = 4 s:
h(4) = -16*4^2+125*4
h(4) = 244 ft
The height of the object after 4 seconds is 244 feet.

Answer: 1675 Ft. = Distance from
fire to the windmill.
Step-by-step explanation:
tan8 = 140/X1.
X1 = 140/tan8 = 996.2 Ft.
tan3 = 140/(996+X2)
996+X2 = 140/tan3 = 2671
X2 = 2671-996 = 1675 Ft. = Distance from
fire to windmill.

Find the Surface Area. I need the answer fast.
Answer:
1615
Step-by-step explanation:
Area of triangle is: A= B•H•1/2
Area of square is A= L•W
39•17•1/2= 331.5
331.5•4= 1326
17•17= 289
Add the square area to the area of the triangles
289+ 1326= 1615
hope this helps chu <3
Answer:
663
Step-by-step explanation:
Since we are finding the area we multiply Length times Width which is a way of finding formal. L x W so the Length is 17 and Width is 39 so
17 x 39 = 663. So the area is 663

Which function is the inverse of f(x) = -x^3 - 9?
Answer:
(2)
Step-by-step explanation:
Let f(x) = y → f-¹(x) = f(y) = x, f(y) is the inverse of f(x)
Thus,
=> -x³ - 9 = y
=> - y - 9 = x³
=> (-y - 9)^(1/3) = x
=> f(y) = x
Inverse is (-y-9)^(1/3)
Replacing the variable, inverse is (-x-9)^(1/3)

Semira’s puppy weighs 12.4 pounds and is growing at a rate of 0.8 pound per week. Cedric’s puppy weighs 9.2 pounds and is growing at a rate of 1.2 pounds per week. Let x represent the time in weeks and y represent the weight of the puppy in pounds. Which system of equations can Semira and Cedric use to determine after how many weeks their puppies will weigh the same?
{y=0.8x+12.4
{y=1.2x+9.2
{y=12.4x+0.8
{y=9.2x+1.2
{y=0.8x+1.2
{y=12.4x+9.2
{y=1.2x+0.8
{y=9.2x+12.4

Solve for B!

* ♡ The Answer ♡
・B = -11/13
*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*
♡ The Explanation/Step-By-Step ♡
・1/7 = 90/91 + B
Switch sides!
90/91 + B = 1/7
Subtract 90/91 from both sides!
90/91 + B - 90/91 = 1/7 - 90/91
Simplify!
90/91 + B - 90/91 : B
90/91 + B - 90/91
90/91 - 90/91 = 0
= B
Simplify!
1/7 - 90/91 : -11/13
1/7 - 90/91
= 13/91 - 90/91
Combine the fractions!
= 13 - 90 over 91
Subtract the numbers! : 13 - 90 = -77
= -77/91
Apply the fraction rule! : -a/b = -a/b
= -77/91
Cancel the common factor! : 7
= -11/13
B = -11/13
