Mrs. Chavez put $8,000.00 in her IRA savings account that offers 8.62% interest compounded annually. She makes no additional deposits or withdrawals. Which amount is closest to the interest Mrs. Chavez will have earned at the end of 4 years?
If Mrs. Chavez put $8,000.00 in her IRA savings account that offers 8.62% interest compounded annually, then she will earn $3136 interest at the end of the 4 years
Total invested amount = $8000
Interest rate = 8.62%
The interest is compounded annually
Time period = 4 years
We know
[tex]A=P(1+\frac{r}{100})^{t}[/tex]
Where,
A = Final amount
P = Principal
r = Interest rate
t = Time period
Substitute the values in the equation
A= [tex]8000(1+\frac{8.62}{100})^{4}[/tex]
A= $11136
Compounded interest = 11136-8000
=$3136
Hence, If Mrs. Chavez put $8,000.00 in her IRA savings account that offers 8.62% interest compounded annually, then she will earn $3136 interest at the end of the 4 years

Evaluate each function for the given value of x , and write the input x and output f(x) as an ordered pair.
f(x) = -12x/5 for x=-1
f (-1) = 12/5 the output for the given input .
How can you tell whether a function is linear or not?
Looking at a function's graph will reveal if it is linear or not with the greatest ease.When a linear function is plotted on a graph, a straight line is formed. A nonlinear function is curved in some way; it does not form a straight line.f(x) = -12x/5
Put x = -1 ⇒ - 12 * -1 /5

A farmer needs to make a 1000 -square-foot rectangular enclosure for her cows. She wants to save money by purchasing the least amount of fencing possible to enclose the area. What whole-number dimensions will require the least amount of fencing?
F. 8ft by 125ft
G. 10ft by 100 ft
H. 20ft by 50 ft
J. 25ft by 40 ft
The dimensions of the 1000-square-foot rectangular enclosure with the least amount of fencing should be 25ft by 40ft.
The amount of fencing needed can be calculated by getting the perimeter of each choice of dimensions.
Perimeter is defined as the distance that surround any two-dimensional shape. For a rectangle, the perimeter is given by the formula
P = 2l + 2w
Solving for the perimeter of each of the following choices:
F. 8ft by 125ft
P = 2l + 2w
P = 2(8) + 2(125)
P = 16 + 250
P = 266ft
G. 10ft by 100ft
P = 2l + 2w
P = 2(10) + 2(100)
P = 20 + 200
P = 220ft
H. 20ft by 50ft
P = 2l + 2w
P = 2(20) + 2(50)
P = 40 + 100
P = 140ft
J. 25ft by 40ft
P = 2l + 2w
P = 2(25) + 2(40)
P = 50 + 80
P = 130ft
The dimensions with the least perimeter will require the least amount of fencing.
Hence, a 1000 -square-foot rectangular enclosure, with dimensions 25ft by 40ft, will require the least amount of fencing.

When striping the practice football field, Mr. Hawkins first painted the sidelines. Next he marked off 10-yard increments on one sideline. He then constructed lines perpendicular to the sidelines at each 10-yard mark. Why does this guarantee that the 10 -yard lines will be parallel?
This ensures that the lines will be parallel since two lines that are perpendicular to one another must also be parallel.
What is a perpendicular line?Two lines that meet or cross at right angles (90°) are known as perpendicular lines in geometry. The word "perpendicular" comes from the Latin "perpendicularis," which denotes a plumb line.
We can write two lines, AB and CD, as AB ⟂ CD if they are perpendicular to one another. The lines are denoted as being perpendicular by the ⟂ symbol.

Step-by-step explanation:
First step. Switch the greater than sign and turn the linear inequality to slope formula. after that graph the line. it is a dashed line due to not being greater than EQUAL to. if not equaled to then it is dotted. then you need a point as your testing point to see if it is shaded in that area. I chose to(0,0) but you could have chose any point. Once you plug in the zeros you will notice you get the false statement of 0 greater than 15. so obviously that is a no so you shade the opposite side of your testing point. phew

When the numerator and denominator of a rational number have no common factor other than 1, we consider it to be its simplified version in fractions. The same method may be used to simplify rational expressions; the only difference is that polynomials are included in the fraction.

Find the 32 nd term of each sequence. 23,30,37,44, ...........
The 32nd term of the arithmetic sequence AP is calculated to be 240.
What basically is an AP arithmetic sequence?In mathematics, an arithmetic progression (AP) is a list and possibly sequence of numbers where each term is collected by adding a sequence towards the term before it.
The fixed number, without regard to arithmetic progression, is signified by the letter 'd.'Common difference => d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1.nth term of AP: an = a + (n - 1) dThe sum of n terms of an AP's => Sn = n/2(2a+(n-1)d) = n/2(a + l), where l = last term of the AP.Finally, here is the answer to the question:
The following are the numbers with in displayed sequence:
23,30,37,44, ...........
The 32nd number in the series must be investigated because it contains 32 terms.
The common difference between two consecutive terms of an AP that are equal is denoted by the letter 'd.'
Let's consider the first term is'a₁' = 23.
Let's consider 'a₂' = 30 is the second term.
Let's consider the third term is 'a₃' = 37.
Substitute the values the above obtained equation; the 32nd term is-
d = a₂ - a₁
Estimate the common difference;
d = 30 - 23
d = 7
Substitute the values in the next formula; the 32nd term is
The formula given will estimate the nth term equation;
nth term of an AP: an = a + (n - 1) d
Total number of terms ; n = 32
Initial term is a = 23
Common difference d = 7
Substitute the given values in nth term formula;
a₃₂ = a + (n - 1) d
a₃₂ = 23 + (32 - 1)(7)
a₃₂ = 23 + 217
a₃₂ = 240
Thus, the 32nd term value of the given arithmetic sequence is estimated to be 240.

What are the cooridinates of the point that partitions segment HE in the ratio of 2:3?
Using proportions, the coordinates of the point C that partitions segment HE in the ratio of 2:3 are found according to the following equation:
C - H = 2/5(E - H).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, we have point C that partitions segment HE in the ratio of 2:3, hence it is 2/5 of the way from H to E, and the rule is given by:
C - H = 2/5(E - H).

What are the properties of logarithms?There are four basic properties of logarithms:
logₐ(xy) = logₐx + logₐy.
logₐ(x/y) = logₐx - logₐy.
logₐ(xⁿ) = n logₐx.
logₐx = logₓa / logₓb.
According to the problem, we will use some of the basic logarithmic properties,
We have been given that expression as

What is variance ?A measure of variability is the variance. It is determined by averaging the squared deviations from the mean. Your data set's variability is shown by its variance. The variance is greater in respect to the mean when the data are more dispersed.
Finding the mean will allow you to compute the population's variance (the average). Squaring the result after deducting the mean from each data point in the sample. The outcomes are squared to make the adverse findings positive.
Data points' deviations from the mean are quantified by their variance. Layman defines variance as the degree to which a set of data (numbers) deviates from the mean (average) value.
