Jake's parents want $100,000 at the end of 40 years. They put their money in an account that yields 4% per year compounded continuously. How much money should jakes parents deposit?
Answers
Answer:
$ 20,189.65
Step-by-step explanation:
Jake's parents want $100,000 at the end of 40 years. They put their money in an account that yields 4% per year compounded continuously. How much money should jakes parents deposit?
From the above question, we are to find the Principal. The formula for Principal compounded continuously =
P = A / e^rt
Where:
A = Amount after time t = $100,000
r = Interest rate = 4%
t = Time in years = 40 years
First, convert R percent to r a decimal
r = R/100
r = 4%/100
r = 0.04 per year,
Then, solve our equation for P
P = A / e^rt
P = 100,000.00 / e ^(0.04×40)
P = $ 20,189.65
Therefore, the amount Jake's parents should invest = $ 20,189.65

x ≈ 261 ft
Step-by-step explanation:
Using the sine ratio in the right triangle
sin50° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{200}{x}[/tex] ( multiply both sides by x )
x × sin50° = 200 ( divide both sides by sin50° )
x = [tex]\frac{200}{sin50}[/tex] ≈ 261 ft ( to the nearest foot )
x ≈ 261 ft
that is the answer

A diameter spans from one end of (in this case, a circle) to the direct opposite end, going through the center-point. The radius, on the other hand, is half of a diameter, and spans only from the center-point to a point on the circle.
In this case:
1) Diameter = 18 km (given)
Radius = 18/2 = 9 km
2) Diameter = 1 x 2 = 2 m
Radius = 1 m (given)
3) Diameter = 17 x 2 = 34 cm
Radius = 17 cm (given)
4) Diameter = 50 mm (given)
Radius = 50/2 = 25 mm
John has a swimming pool, in which the center of the pool to the edge is 3 meters. What is the diameter? Simply multiply 3 with 2:

Solve for x:
5x - 3y = 22
10x - 4y = 46
Answers
Answer:
x=5, y=1
Step-by-step explanation:
Isolate x for 5x-3y=22
5x-3y=22
Add 3y to both sides
5x-3y+3y=22+3y
Simplify
5x=22+3y
Divide both sides by 5
5x/5=22/5+3y/5
Simplify
x=22+3y/5
Substitute x=22+3y/5
10*22+3y/5-4y=46
Simplify 10*22+3y/5-4y
10*22+3y/5=2(3y+22)
=2(3y+22)-4y
Expand 2(3y+22)
=6y+44-4y
Simplify 6y+44-4y
=2y+44
Isolate y for 2y+44=46
2y+44=46
Subtract 44 from both sides:
2y+44-44=46-44
Simplify
2y=2
Divide both sides by 2;
2y/2=2/2
Simplify;
y=1
For x=22+3*1/5 substitute y=1
y=22+3*1/5
22+3*1=25
=25/5
Divide the numbers;25/5=5
=5
x=5
The solutions to the system of equations are;
x=5, y=1

1 Katie is raising money to buy
a dog. She starts a
neighborhood babysitting service.
She paid $40 for a CPR class and
charges $5 per kid. Write an
equation she could use to calculate
her profit, p, if she has k kids.
O p = 5k - 40
P = 5k + 40
O p = 40k + 5
k = 40p - 5
Answers
Answer:
p = 5k - 40
Step-by-step explanation:
Since we're finding the profit (p), it's not the last answer choice because it's finding kids (k).
Because we have to take out from her profit whatever Katie spent, we would have -40.
Because she'd charging $5 per kid, or $5 per k, we would have 5k.
So now we know the profit is whatever she makes, then minus whatever she spent. So:
p = 5k (what she makes) - 40 (what she spent)
p = 5k - 40
Answer:
O p = 40k + 5

Katie is raising money to buy a dog. She starts a neighborhood babysitting service.

Answers
Answer:
x = -1, y = -1.
Step-by-step explanation:
-3x +y = 2
7x – 8y = 1
We can use the elimination method to solve these:
Multiply the first equation by 8:
-24x + 8y = 16
Now add this to the second equation:
-17x -8y + 8y = 17
-17x = 17
x = -1.
Plug x = -1 into the first equation:
-3(-1) + y = 2
3 + y = 2
y = -1.
