Answer:
After 31 months, Desmond first have enough money to purchase a used car.
Step-by-step explanation:
Since we have given that
Saving per month for a used car = $25
Each month he is able to save = $5 more than the previous month
If we have $3000 to purchase a used car.
So, we need to find the number of months Desmond to have enough money.
Our sequence will be
25,30,35,..............3000
So, it becomes,
Months can't be negative, So,
n = 31 months.
Hence, After 31 months, Desmond first have enough money to purchase a used car.

Tierra is making steps for a doll houseshe has cut a piece of wood that measures 1.5 centimeters wide and 30 centimeters longeach step will measure 15 millimeters by 4 millimetersshe will make 21 steps for her doll housewhich are the dimensions of the wood that remains after tierra finishes making the 21 steps?
The dimensions of the wood that remains after Tierra finishes making the 21 steps is 1.185 cm by 21.6 cm
How to determine the remaining dimensions?The given parameters are:
Wood = 1.5 cm by 30 cm
Each cut = .15 mm by 4 mm
Steps = 21
The remaining dimension is calculated as:
Remaining = 1.5 cm - 21 * .15 mm by 30 cm - 21 * 4 mm
Express mm as cm
Remaining = 1.5 cm - 21 * .015 cm by 30 cm - 21 * 0.4 cm
Evaluate the difference
Remaining = 1.185 cm by 21.6 cm
Hence, the dimensions of the wood that remains after Tierra finishes making the 21 steps is 1.185 cm by 21.6 cm

Answer:
[tex]\boxed{\sf x = 11.57}[/tex]
Step-by-step explanation:
[tex] \sf {x}^{2} = {3.6}^{2} + {11}^{2} [/tex]
Calculate 3.6 to the power of 2 to get 12.96, and 11 to the power of 2 which will give you 121.
[tex] \sf {x}^{2} = 12.96 + 121[/tex]
Add 12.96 and 121.
[tex]\sf {x}^{2} = 133.96[/tex]
Now, we'll take the square root of both sides of the equation.
[tex] \sf \sqrt{ {x}^{2} } = \sqrt{133.96} [/tex]

What is the factored form of x²y³ - 2y³ - 2x² + 4?
y³ (x² − 2) +2 (-x² + 2)
Answer:The third option is correct
Step-by-step explanation:
Answer:
(y³ - 2) (x² - 2).
Step-by-step explanation:
x²y³ - 2y³ - 2x² + 4
= y³ (x² - 2) - 2(x² - 2)
(x² - 2) is common to both parts so we have:

You chose an EXPONENTIAL model with the equation:
y=4.04·0.56x
In the context of the tennis balls:
(1) What does 4.04 mean?
(2) What does 0.56 mean?
Equation: y = 4.04·0.56^x
(1) What does 4.04 mean?Solution: Here in the exponential model, the height is 4.04 feet when the bounce number is 0. It represents the initial height. (original, starting value)
(2) What does 0.56 mean?Solution: 0.56 represents the represents the growth rate of how much the height will decrease with the amount of bounces. (growth factor)
Extra's :x represents the unit of measure of bounces.

Answer:
Pr(Cb) & Pr(cost $15) = 15(Ncb)/(T1×T3)
Step-by-step explanation:
Classification of the book in to 3
First let's assign terms to each probability
Let:
T1= total number of type of Reader's group
T2 = total number of Type of book
T3 = total number of type of Cost
Probability of child's book and cost $15= Pr(Cb) & Pr(cost $15)
Then find probability of child's book and cost separately:
Pr of child's book = Pr(Cb)
Pr(Cb) = (number of child's book)/ total number of type of group
Ncb = number of child's book
Pr(Cb) = Ncb/T1
Pr (cost $15) = $15 book/total number of cost
Pr (cost $15) = 15/T3
probability of child's book and cost $15 = Pr(Cb) × Pr (cost $15)
= Ncb/T1 × 15/T3
Pr(Cb) & Pr(cost $15) = 15(Ncb)/(T1×T3)

How to Calculate Return on Investment (ROI)?The primary indicator of the profit made from any venture is return on investment (ROI). A gain or loss from an investment in relation to its cost is compared using this ratio. Whether you are assessing the success of your stock portfolio, taking into account a company investment, or choosing whether to start a new project, it is helpful in evaluating the current or projected return on an investment.ROI and other cash flow indicators, including internal rate of return (IRR) and net present value (NPV), are important metrics that are used in business research to assess and prioritize the attractiveness of various investment options.Despite the fact that ROI is a ratio, it is usually stated as a percentage.It's crucial to keep a few things in mind when assessing ROI figures. First off, because it is inherently simpler to understand than a ratio, ROI is frequently represented as a percentage. Second, because investment returns can be either positive or negative, the ROI calculation includes the net return in the numerator.To learn more about return on investment, refer to

Coordinates are represented in the form of (x, y)
To know the x coordinates see the value on the x-axis.
To know the y coordinates see the value on the y-axis.
From there we can identify:
A = (x, y) = (-4, 4)
B = (x, y) = (2, 2)
C = (x, y) = (0, -5)
D = (x, y) = (-3, -2) ← Required answer.

1. a motor car race is 500 miles long and consists of completing laps of a circular speedway
that has a circumference of 2.5 miles. for which of these functions does y represent the
number of miles a motor car has left to go in the race if x represent the number of laps
completed by the motor car?
a. y = -2.5x -500
b. y = -2.5x + 500
c. y = 2.5x -500
d. y = 2.5x + 500
The function y = 2.5x + 500 represents the total number of miles if the motor car race is 500 miles long, option (d) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
y represents the number of miles a motor car has left to go in the race
x represents the number of laps completed by the motor car
The total number of miles if we consider only circular speedways = 2.5x
The total number of miles:
y = 2.5x + 500 (because 500 is the constant)
Thus, the function y = 2.5x + 500 represents the total number of miles if the motor car race is 500 miles long option (d) is correct.
