Vladimir is looking to retire in 10 years. He has a plan to put $25,000 into an investment today that earns interest at a fixed amount per year. What would be a reasonable domain and range for a function modeling the total amount of the investment, including interest?
25 Points for the correct answer

Answers

The domain and range for a function modeling the total amount of the investment, including interest are as follows;

Domain, X = {0<= years <= 10}Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + 10R)}

The starting principal amount, P is $25,000.

Let the interest rate per year, be represented as, R (%)

Time of investment, T = 10 years

In essence, after 10 years, the total amount Vladimir has is;

Total amount = 25,000( 1 + xR).

In essence, the domain (No. of years ) is;

Domain, X = {0<= years <= 10}

Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + xR)}

Answers

Answer:

Equation: y = -1x + 4

Step-by-step explanation:

In order to create an equation, you need to put it in slope-intercept form ( y = mx + b ). The best way to figure out to create your equation is to graph the points. 'Y' means the y-axis. 'mx' refers to the slope of a particular line and b is concluding where the line crosses the y-axis.

i dont really pay attention and im failing. this is very forgein to me it just looks ike a cluster of numbers and signals. cn you step by step expail it please i will give a brainly!

Answers

Answer:

1. k=-9

2. a=-12

Step-by-step explanation:

1. -12(k+4)=60

use distributive property

   -12k-48=60

add 48 to both sides

   -12k=108

divide both sides by -12

   k=-9

2. 8(3a)=9(2a-4)

   use distributive property

   24a=18a-36

   subtract 18a on both sides

  6a=-36

  divide both sides by 6

   a=-12

Write the slope intercept form of the equation for f the line through the given points

Answers

Answer:

y = -2x - 4

Step-by-step explanation:

First, I'll find the slope by subtracting the y-values and x-values of each point from each other, as shown below:

(-2 - (-4))/(-1 - 0) = 2/-1 = -2

We already have the y=intercept: (0, -4). From this, we can write a y = mx + b (slope intercept form) equation, with m being our slope and b being our y-intercept. It looks like y = -2x - 4.

Answers

Answer:

3/20x−3

Step-by-step explanation: TOOK THE FOR K12 HOPE THIS HELPS

The difference of the given expression is 3/20 x - 3.

Given that, (2/5x−1)−(1/4x+2).

What is the subtraction of expressions?

To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.

Now, (2/5x−1)−(1/4x+2)

= (2/5 x - 1/4 x) -1 - 2

= (8/20 x - 5/20 x) - 3

= 3/20 x - 3

Therefore, the difference of the given expression is 3/20 x - 3.

You should expand the original lot by…
Please type ft to represent feet.

Answers

So the amount you are increasing it by is equal on both sides. Firstly let’s look at the factors of 48, (1,2,3,4,6,8,12,16,24 and 48) the only factors that are can be equal increase from 4 and 6 is by 2 ft giving us a length of 8 and a width of 6

Answer:

2 ft

Step-by-step explanation:

Given:

Find x:

(6 + x)(4 + x) = 48x² + 10x + 24 = 48x² + 10x + 25 = 49(x + 5)² = 49x + 5 = 7x = 7 - 5x = 2
