A deposit of $2,000 is made in a trust fund that pays 5.5% interest, compounded continuously. It is specified that the balance will be given to the college from which the donor graduated after the money has earned interest for 30 years. How much will the college receive? (Round your answer to the nearest cent.)

Answers

The formula for compounded continuously is A = pe^rt.

What is given?

(A)mount = ?
(P)rincipal = $2000
e = 2.7183 (always)
(r)ate = .05 (turn into decimal)
(t)imd = 20 years

Plug into formula:
A = 2000*2.7183^(.05*20)
A = $5436.60

Which digit(s) make the solution of the equations the whole number? 5x-496=1.34...

Answers

Answer:

x≈ 100

Step-by-step explanation:

Given the equation

5x-496=1.34...

We are to find the value of x to the nearest whole number

Add 496 to both sides

5x-496+496 = 1.34+496

5x = 497.34

x = 497.34/5

x = 99.468

x ≈ 100

Hence the value of x to nearest whole number is 100

Answers

Answer:

y = -1x + 2

Step-by-step explanation:

We need to find y = mx + b

Use the following equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Plug in the values

[tex]\frac{-1-0}{3-2}[/tex]  = [tex]\frac{-1}{1} = -1[/tex]

We have found the slope(m) which is -1

We have to find y-int b

Plug in any given x,y into the slope formula

-1 = -1(3) + b

-1 = -3 + b

2 = b

At last the formula is

y = -1x + 2

Answer:

Combine like terms:

x=5

what is the answer to -4(2d+3)+2(-d+4)?

Answers

Answer:

-10d-4

Step-by-step explanation:

Well, you're in luck because I LOVE distributive property!!!

-4(2d+3) Multiply -4 by 2d to get -8d, and multiply -4 by 3 for -12, so the result would be -8d-12!

Then, 2(-d+4) and therefore 2 times -d (you can just say -1d) to get -2d and 2*4 would be 8 to make -2d+8!

Now you combine them: -8d-12+-2d+8

Combine like terms!

-10d-4 would be your answer.

Marian buys a dress that costs $32.00. She pays 10%

How much does she pay for the dress, with tax?
A. $5.20
B. $35.20
C. $34.00
D. $28.80
Please help

Answers

Answer:

B, $35.20

Step-by-step explanation:

32 increase 10% =

32 × (1 + 10%) = 32 × (1 + 0.1) = 35.2

answer is 35.20 because if you do 3.20 plus 32 that would equal 35.20

Which is the graph of the linear inequality y < 3x + 1? On a coordinate plane, a solid straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the left of the line is shaded. On a coordinate plane, a solid straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the right of the line is shaded. On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the left of the line is shaded. On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the right of the line is shaded.

Answers

For this case we have the following inequality: y < 3x + 1 < br/ >

What we must do is to evaluate a point of the Cartesian plane and verify if it is in the shaded region.

The shaded region represents the solution of the system of equations.

For the point (0, 0) we have:

0 < 3(0) + 1 < br / >

0 < 0 + 1 < br / >

0 < 1 < br / >

Therefore, the point (0, 0) is in the shaded region because it satisfies the inequality.

Then, the points that are on the line, are not part of the solution because the sign is of less strict.
