The remainder theorem conclude given that F(-5)=17
When, x= -5
x+5=0
So, F(-5) = 17
What is Remainder Theorem explain?According to the remainder theorem, the result of dividing p(x) by (x - a) is p. (a). According to the factor theorem, (x - a) can only be a factor of p(x) if f(a) = 0. It is used to locate the rest. A linear polynomial's status as a factor of the input polynomial is determined using this method.
The remainder theorem is used to calculate the remainder when a polynomial is split by a linear polynomial. We are aware that long division of polynomials can be used to find the remainder after dividing one polynomial by another. The remainder can instead be discovered using the remainder theorem.

Postal Clerks weigh each piece of mail to find a mailing cost. It costs $0.45 per ounce to mail an item. If Sara mails two items having weights of 7 ounces and 6 3/5 ounces, how much does she pay?
we get that the total cost that Sara has to pay to mail these two mails will be equal to 4 6.12.
Sara has 2 items:
Weight of 1st item = 7 ounces.
Weight of second item = 6 3/5 ounces = 33 / 5 ounces.
Total Weight of items to be mailed = 7 ounces + 33 / 5 ounces
Total Weight = 35 + 33 / 5 ounces = 68 / 5 ounces.
Now, cost of mailing 1 ounce per mail = $ 0.45
Cost of mailing 68 / 5 ounce of mails = 68 / 5 × $ 0.45
Total cost = $ 6.12
Therefore, we get that the total cost that Sara has to pay to mail these two mails will be equal to 4 6.12.

hile traveling across flat land, you notice a mountain directly in front of you. its angle of elevation (to the peak) is 4.5°. after you drive 13 miles closer to the mountain, the angle of elevation is 8°. approximate the height of the mountain. (round your answer to three decimal places.)
The height of the mountain using the angles of elevation is 2.346 miles
How to find the height of the mountain using angle of elevation?let
x = distance from the mountain to your current position
h = height of the mountain
Therefore, using trigonometric ratios,
angle of elevation of the current position to the mountain = 8°
angle of elevation of the former position to the mountain = 4.5°
Therefore,
tan ∅ = opposite / adjacent
where
∅ = angle of elevation
tan 8 = h / x
tan 4.5 = h / x + 13
Hence,
x tan 8 = h
(x + 13) tan 4.5 = h
using substitution,
x tan 8 = (x + 13) tan 4.5
x tan 8 = x tan 4.5 + 13 tan 4.5
0.1405408347x = 0.07870170682x + 1.02312218872
0.1405408347x - 0.07870170682x = 1.02312218872
0.0613x = 1.02312218872
x = 1.02312218872 / 0.0613
x = 16.6900489396
x = 16.690 miles
Therefore,
h = 16.6900489396 × tan 8
h = 16.6900489396 × 0.1405408347
h = 2.34561947798
h = 2.346 miles.
Therefore, the height of the mountain using the angles of elevation is 2.346 miles

Solve inequality.
y-13<2
To solve the inequality, add 13 to both sides. The solution is y < 15 or (∞, 15)
Tips to solve linear inequalities:
Isolate the variable on one side by using subtraction or addition. Subtraction and addition will not change the inequality.Use division or multiplication to find the solution. Multiplication and division by a positive number will not the inequality. However, if we multiply or divide both sides with a negative number, we need to flip the inequality direction.Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis ( or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.
Example: x ≥ 2 can be written as [2, ∞), while
x > 0 is written as (2, ∞)
The given problem:
y-13 < 2
Add 13 to both sides. Adding a number to both sides will not change the inequality. Hence,
y -13 + 13 < 2 + 13
y < 15
Using the interval notation, the solution is (∞, 15)

As we can see in the diagram, the triangle is a right-angled triangle, meaning that one of the angles inside the triangle has a measure of 90°.
Whenever we have a right-angled triangle and are given the lengths of two of its sides, and we are asked for the length of the third side, we must use the Pythagorean theorem, which states that:
[tex]\boxed{\mathrm{a^2 + b^2 = c^2}}[/tex],
where:
c = hypotenuse (longest side, opposite to 90° angle)
a, b = the two other sides of the triangle.
In this question, we are asked for the value of x, which is the hypotenuse of the given triangle, while the lengths of the other two sides are 15 and 36.
Therefore, using the Pythagorean theorem, we get:
[tex]15^2 + 36^2 = x^2[/tex]
⇒ [tex]x = \sqrt{36^2 + 15^2}[/tex]
⇒ [tex]x = \sqrt{1296 + 225}[/tex]

Find the volume (in units3) generated when the region between the curves is rotated around the given axis. y = x3, y = 0, and y = 27 rotated around the y-axis
The Volume generated when the region between the curves is rotated around the y - axis is 1216500335.46
Volume of the curves:
The volume of the solid formed by revolving the region bounded by the curve x = f(y) and the y-axis between y = c and y = d about the y-axis is given by
V = π ∫dc [f(y)]2dy.
The cross-section perpendicular to the axis of revolution has the form of a disk of radius R = f(y).
Given,
y = x³
Here we have to find the volume along to the y axis.
With limit as y = 0 and y = 27.
When we apply the values it can be written as,
=>[tex]V=\pi \int\limits^0_{27} {(x^3)^2} \, dx[/tex]
[tex]\implies V=\pi \int\limits^0_{27} {(x^6)} \, dx[/tex]

Solve by Elimination Algebra 2 A park charges $10 for adults and $5 for kids. How many adult tickets and kid tickets were sold, if a total of 524 tickets were sold for a total of $3860 There were _ adults and _ kids tickets sold
Answer:
There were 248 adult tickets and 248 kid tickets.
Step-by-step explanation:
a = number of adult tickets
k = number of kid tickets
a + k = 524 10a + 5k = 3860
Multiply the equation on the right all the way through by -5 so that we can eliminate the k's when we add the equations together.
-5(a+ K) = 524(-5)
-5a - 5k = -2620
Add the two equations together:
-5a - 5k = -2620
10a + 5K = 3860
5a = 1240 Divide both sides by 5
a = 248 There are 248 adult tickets. Plug in 248 for a in either of the original equations.
a + k = 524
248 + k = 524 Subtract 248 from 524 to find the number of kid tickets.
There are 276 kid tickets.
Check:
Plug in 276 for k and 248 for adult to both equations to see if they work
a + k = 524
248 + 276 = 524
524 = 524
10a + 5k = 3860
10(248) + 5(276) = 3860
2480 + 1380 = 3860
38060 = 3860
cynthia besch wants to buy a rug for a room that is 19 ft wide and 29 ft long. she wants to leave a uniform strip of floor around the rug. she can afford to buy 299 square feet of carpeting. what dimensions should the rug have?
The dimension which this rug should have is 23 feet × 13 feet.
How to calculate the dimensions of this rug?Mathematically, the area of a rectangle can be calculated by using this formula;
A = LW
Where:
A represents the area of a rectangle.l represents the length of a rectangle.w represents the width of a rectangle.Let x represent the width of this rug.
Also, the dimension of this rug is given by:
299 = (29 - 2x) × (19 - 2x)
299 = (29 - 2x)(19 - 2x)
Evaluating the equation, we have:
299 = 551 - 58x - 38x + 4x²
4x² - 58x - 38x + 551 - 299 = 0
4x² - 96x + 252 = 0
Dividing all through by 4, we have:
x² - 24x + 63 = 0
x² - 21x - 3x + 63 = 0
x(x - 21) - 3(x - 21) = 0
(x - 3)(x - 21) = 0
x = 3 or 21 feet.
Note: The plausible solution is x = 3.
Therefore, the width and length of this rug is given by:
Length = 29 - 2(3)
Length = 29 - 6
Length = 23 feet.
Width = 19 - 2(3)
Width = 19 - 6
Width = 13 feet.
In conclusion, the dimension of this rug is 23 feet × 13 feet.

Answer:
5,000
Step-by-step explanation:
Answer:
Money spent on playstation games per week: =$8169861
Money spent on other video games per week: = $5542467
Step-by-step explanation:
Hi to answer this first, we have to calculate how much Americans spend on non Playstation video games. So, we have to subtract the money spent on Sony Playstation games to the total money spent:
$1958904.00-$1167123.00= 791781 on other video games per day
Now, since each week has 7 days. We have to multiply each daily amount by 7.
Money spent on playstation games per week: $1167123.00 x 7=8169861
Money spent on other video games per week: $791781 x 7= 5542467

Write an equation of the line with the given slope, m, and y-intercept (0,b), m=7, b=5
Answer: y = 7x + 5 (maybe, please make sure, I'm very doubtful of myself sometimes)
Step-by-step explanation:
1. With the given numbers, m is slope, so 7 is the slope and b is y-intercept, and 5 is the y-int in this case.
2. This is hinting that the equation is in slope intercept form, which is y = mx + b.
3. Since y = mx + b is the formula, then it means y = 7x + 5 is the likely answer
