Calculate the average GPA for Andy after each of his four years of high school if he gets a good start his Freshman year?
Answer:
Freshman Sophomore Junior Senior
3.5 3.25 3.0 3.2
Step-by-step explanation:
Average GPA = Total GPA / number of years
Freshman Year (1 year): 3.5 = 3.5
Sophomore Year (2 years) = (3.5 + 3.0) = 6.5/2 = 3.25
Junior Year(3 years) = (3.5 + 3.0 + 2.5)/3 = 9.0/3 = 3.0
Senior Year(4 years) = (3.5 + 3.0 + 2.5 + 3.8) = 12.8/4 = 3.2
An isolated agricultural country has two distinct regions: a lowland plain and an upland of rugged hills. On one unit of land on the PLAIN, a farmer can raise 10 bushels of grain or graze 10 sheep. On one unit of land in the HILLS, a farmer can raise 2 bushels of grain or graze 4 sheep.
Determine which region has the absolute advantage for sheep production. Explain your answer.
The region that has the absolute advantage for sheep production is in the hills because food grows faster when exposed to heat and rain water.
How to illustrate the information?It shouldbe noted as opposed to being exposed to sunlight all day, food develops more quickly in the hills when it is exposed to heat and rain.
For uphill = 10 sheep = 10 bushels
For uphill = 1 sheep = 1 bushels
For down plain = 4 sheep = 2 bushels
For down plain = 1 sheep = (1 / 2 ) bushels
Therefore, then for 1 sheep, it should be noted that 1 bushel is required in the hills.
Therefore, the region that has the absolute advantage for sheep production is in the hills because food grows faster when exposed to heat and rain water.

48 persons are present at the gathering. There are seven times more adults than children in the world. The number of women is two times that of men. If there are five females (young women) in attendance. The total number of male adults are15
The total number of people are in the party is equal to 48
Let the number of children be x
So, the number of adults in the party is equal to 7 x
x + 7 x =48 ( This is a linear equation)
So, the number of children in the comes to be 6
Number of adults in the party = 6 * 7 = 42
Now let the number of males be y
So total number of females = 2 y
Y+2y = 48 ( This is a linear equation)
Y=16
Therefore, the number of males is 16 and the number of females is 32
The number of children in the party is 6 and the female child is equal to 5

Find the horizontal limit(s) of the following function:
f(x)=2x3−8x2−9x/11−10x−5x3
The horizontal limit of the given function is given as follows:
y = -2/5.
What is a limit?A limit is given by the value of function f(x) as x tends to a value. For a standard function, we just calculate the numeric value of a function.
However, in this problem, an horizontal limit means that x goes to infinity, hence it we replace and calculate the numeric values we would have a fraction of infinity divided by infinity as a result, which is an undetermined limit.
Then, we use the algorithm to solve an infinity limit, in which we consider just the term with the highest exponent of both the numerator and of the denominator.
Hence:
[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{2x^3}{-5x^3} = \lim_{x \rightarrow \infty} -\frac{2}{5} = -\frac{2}[5}[/tex]

A total of $35,000 is to be invested, some in bonds and some in certificates of deposit (CDs). If the amount invested
in bonds is to exceed that in CDs by $1,000, how much will be invested in each type of investment?
The amount invested in CDs is S
The amount invested in bonds is
The amount invested in each type of investment should be $17,000 and $18,000, respectively, as this problem is based on simple interest.
What is a simple mathematical interest?Calculating the amount of interest that will be owed on a sum of money at a certain rate and for a specific period of time is possible using simple interest. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.
based on the facts provided;
Calculating the investment amount:
Since the certificate of deposit is assumed to be x in this instance, the bond should be $35,000 - x.
The formula now should be
($35,000 - x) - x = $1,000
$35,000 - 2x = $1,000
$34,000 = 2x
x = $17,000
So, the bond should be
= $35,000 - $17,000
= $18,000

The explicit formula of the sequence is Tn = 30 - 20(n - 1)
How to determine the explicit formula of the sequence?The recursive formula of the sequence is given as
f(1) = 30, f(n) = 2 • f(n - 1) - 50
The above means that
f(n) = 2 • f(n - 1) - 50
f(1) = 30
Substitute 2 for n
So, we have
f(2) = 2 • f(2 - 1) - 50
Evaluate the difference
So, we have
f(2) = 2 • f(1) - 50
Substitute f(1) = 30 in f(2) = 2 • f(1) - 50
f(2) = 2 • 30 - 50

5 Four friends volunteered to help Mr. Kirby build a new fence around
his property. If the property had a perimeter of 880 ft., how many feet
of fence would each man, including Mr. Kirby, have to build?
If a function is differentiable, then it is continuous. True or false?
The sum of three lengths of a fence rages from 31 to 40 inches. Two side lengths are 9 and 12 inches. If the length of the third side is x inches, write and solve a compound inequality to show the possible lengths of the third side
Answer:
10 ≤ x ≤ 19
Step-by-step explanation
The sum of the three lengths is 9 + 12 +x = 21 + x
We know the sum ranges from 31 to 40
So we get the inequality
31 ≤ 21 + x ≤ 40
Subtracting 21 from each part of this inequality give
31-21 ≤ x ≤40-21
10 ≤ x ≤ 19
The compound inequality to show the possible lengths of the third side is 10 ≤ x ≤ 19.
What is inequality?A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.
Now it is given as,
Range of sum of three lengths of a fence = 31 to 40 inches
Length of two sides = 9 and 12 inches
Length of third sides = x inches
So, length of sum of three lengths of a fence = 9 + 12 + x
⇒ length of sum of three lengths of a fence = 21 + x
∵ Range of sum of three lengths of a fence = 31 to 40 inches
31 ≤ length of sum of three lengths of a fence ≤ 40
⇒ 31 ≤ 21 + x ≤ 40
Subtracting 21 we get.
10 ≤ x ≤ 19
Thus, the compound inequality to show the possible lengths of the third side is 10 ≤ x ≤ 19.

Write a polynomial that will be the area of the framed picture.
What will be the area of the picture with the frame if x=3?
If the width of the painting is w, then its length is 2w. Then, since the frame is 2 inches thick on each side of the painting, its width is w+4 and its length is 2w+4. So the area of the rectangle bounded by the frame (which includes both the area of the frame and the area of the painting) is (w+4)(2w+4).
The area of the painting is w×2w=2w2, and the area of the frame is 196 square inches, so the area of the two combined is 2w2+196. However, that is the same area as the other one I described, so we can then equate the two, i.e. (w+4)(2w+4)=2w2+196. You can then solve that equation for w, and hence find all of the relevant dimensions.

A telephone pole has a wire attached to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor point is 56 feet less than the height of the pole. If the wire is to be 8 feet longer than the height of the pole, what is the height of the pole?
The distance first from bottom of both the pole to the anchor point is approximately 56 feet smaller than the height of the pole, hence 44 feet cannot be the height of the pole. the height of both pole is 496 feet.
What exactly is a quadratic equation?In mathematics, a quadratic equation is a second-degree equation of both the form ax2 + bx + c = 0. The coefficients are a and b, the constant term is c, and the variable is x. Because the variable x has a second degree, this quadratic equation has two roots or answers.
According to the given data:A telephone pole is said to have a cable attached to its top that is secured to the ground. The distance from the pole's bottom to the anchor point is 56 feet less than the pole's height. So the distance from the bottom of the pole to the anchor point is:
x - 56
The wire must be 8 feet longer than just the height of the pole, thus the wire length would be:
x + 8
We know that the length of the wire is the hypotenuse of a right triangle, thus we can apply Pythagoras' theorem as follows:
(x + 8)² = x² + (x - 56)²
x² + 16x +64 = x² + x² - 112x + 3136
x² + 16x +64 = 2x² - 112x + 3136
2x² + 32x + 128 = x² - 56x + 1568
2x² + 32x + 128 - x² + 56x - 1568 = 0
x² - 88x + 1440 = 0
The value pf x will be:
x = 44
x = 496
