Answer:
1. (x+9)(x-5)
2. (x+8)(x-4)
Step-by-step explanation:
use x-box method to simplify both problems
Final answer:
To factor the quadratic expressions, we look for pairs of numbers that multiply to give the constant term and add to give the coefficient of the middle term, resulting in the expressions (x - 9)(x - 5) for the first and (n + 8)(n - 4) for the second.
Explanation:
The question relates to factoring quadratic expressions, which is a fundamental skill in algebra. Specifically, we are looking to factor the expressions [tex]x^2[/tex] - 14x + 45 and [tex]n^2[/tex] + 4n - 32 completely. Factoring involves finding two binomial expressions that multiply together to give the original quadratic expression.
To factor [tex]x^2[/tex] - 14x + 45, consider two numbers that multiply to 45 and add to -14. These numbers are -9 and -5. Therefore, the factored form is (x - 9)(x - 5).
To factor [tex]n^2[/tex] + 4n - 32, we again look for two numbers that multiply to -32 and add to 4. These numbers are 8 and -4. Thus, the factored form is (n + 8)(n - 4).
A tile store charges $607.50 to install 135 square feet of tile. Assuming they charge the same rate
per square foot regardless of the amount of tile installed, how much would they charge to install
840 square feet of tile?
Translate to a proportion:
square feet
square feet
They would charge
to install 840 square feet of tile.
The unit price for installation per square foot of tile is
Answer:
the tile is 4.50 per square foot to install
it will cost 3780.00 to install 840 square feet
Step-by-step explanation:
divide 607.50 by 135 to find out the price per square foot to install
multiply the price per square foot by the number of square feet you are installing so 4.50 X 840

B.Will was stuck in traffic during the second and third hour of his trip so he was travelling slowly.
C.Will’s destination was 160 miles from where he started.
D.Will travelled at the fastest speed in the very beginning of his trip.
Answer:
C
Step-by-step explanation:
none of the others are graphically correct
Answer:
C, "Will's destination was 160 miles from where he started."
Step-by-step explanation:
The first and second choices are absurd. It doesn't give any reason or evidence that he stopped during that time. The time does not line up either. D, does not make sense because he only traveled 40 miles in 2 hours. But from hour 3 to 5 he traveled 120 miles.

I’m circle R with m angle QRS=82 and QR=16 units find the of arc length of QS. Round to the nearest hundredth
The length of arc QS in circle R is approximately 22.9 units. This is determined by using the formula for arc length in a circle, which is the radius times the angle (in radians). The angle was first converted from degrees to radians.
Explanation:To find the length of arc QS in circle R, we need to use the formula for the arc length. The arc length of a circle is given by the formula Length = radius * angle (in radians). The angle is provided as 82 degrees, and the radius QR is given as 16 units.
First, we need to convert the angle from degrees to radians. We use the formula: radians = degrees * (π / 180). Hence, 82 degrees is approximately 1.43117 radians.
Now, let's substitute our values into the formula. Length = 16 units * 1.43117 radians.
Hence, the arc length of QS is approximately 22.9 units when rounded to the nearest hundredth.

A bus with kids and a truck with their bags started moving from the school to the camp at the same time. The speed of the bus was 60 mph. The speed of the truck was 45 mph. It took kids 3 hours to reach the camp. How long did they have to wait for their bags?
The kids have to wait for 1 hour to get their bags.
Step-by-step explanation:
Given that,
A bus with kids and a truck with their bags started moving from the school to the camp at the same time.
The speed of the bus was 60 mph.It took kids 3 hours to reach the camp.To find the distance traveled by the bus :
⇒ Distance = Speed × Time
⇒ 60 × 3
⇒ 180 m
∴ The distance is 180 m.
To find the time taken by the truck to reach the camp :
The speed of the truck was 45 mph.We found the distance as 180 m.Time taken = distance / speed.
⇒ 180 / 45
⇒ 4 hours.
∴ The time taken by the truck to reach the camp is 4 hours.
To find how long the kids have to wait for their bags :
The time taken by the truck to reach the camp - the time it took for the kids to arrive.
⇒ 4 hours - 3 hours
⇒ 1 hour.
∴ The kids have to wait for 1 hour to get their bags.
The bus traveled 180 miles to the camp in 3 hours at 60 mph, while the truck took 4 hours at 45 mph to cover the same distance. Hence, the kids had to wait 1 hour for their bags to arrive.
Travel Time and Waiting Time
To determine how long the kids had to wait for their bags, we need to calculate the time it took for the truck to reach the camp.
The bus travels at a speed of 60 mph and it took the kids 3 hours to reach the camp. The distance to the camp can be calculated using the formula:
Distance = Speed × TimeTherefore, the distance is 60 mph × 3 hours = 180 miles.Next, we calculate the time it took for the truck, traveling at 45 mph, to cover the same distance:
Time = Distance / SpeedThus, the truck's travel time is 180 miles / 45 mph = 4 hours.Since the kids took 3 hours to reach the camp and the truck took 4 hours, the kids had to wait for:4 hours - 3 hours = 1 hour.Therefore, the kids had to wait for 1 hour for their bags to arrive.

On a separate sheet of paper graph the following function. In the answer box describe the function.
f(x) = 2[x] – 3
Answer:
Answer
Step-by-step explanation:
The function is a greatest integer function, which is a step function.
The function f(x) = 2[x] - 3 features a step-like graph due to the floor function [x]. To graph it, calculate f(x) for integer values, plot the points, and draw horizontal lines between them. The function's range in this context is specified to be between 0 and 20.
Explanation:The function given is f(x) = 2[x] - 3, where [x] denotes the greatest integer function, also known as the 'floor' function, which returns the greatest integer less than or equal to x. This type of function creates a step-like graph. When graphing this function, you'll notice that for every integer value of x, the function will take on a constant value until the next integer is reached, at which point it will jump up to the next 'step'.
To graph this function, you should first calculate the values of f(x) at various integer points within the given range. Then plot these points on a coordinate plane and create horizontal lines to represent the function's value between each pair of consecutive integer x values. For non-integer values of x, the function value will be based on the floor of x. Label your graph with f(x) and x. Make sure to scale the x and y axes with the maximum values, considering that in this case we are dealing with 0 ≤ x ≤ 20.

You spend $62 on a game, receive $50 for painting a fence, and give $10 to your friend. You have $44 left.
How much money did you start with?
Answer:
You started with $66.
Step-by-step explanation:
The equation would be:
[tex]x-62+50-10=44\\ x-22=44\\ x=66\\[/tex]
To check the answer:
[tex]66-62+50-10=44\\4+50-10=44\\54-10=44\\44=44[/tex]
We started with $66 initially.
What is Algebra?Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. It tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.
As per the given data:
Money spend on game (g) = $62
Money received for painting a fence (p) = $50
Money given to friend (f) = $10
Money left = $44
To find out the money we had initially:
Let's assume we had $x.
Money left = x - g + p - f
44 = x - 62 + 50 - 10
44 = x - 22
x = $66
Hence, We started with $66 initially.

Given f(n) is a geometric sequence where f(3)=32 and f(9)=72, find f(16).
I think the answer may be 64/27, but I don't know for sure.
Answer:
f(16)=162
Step-by-step explanation:
-In a geometric sequence, the quotient between any tow consecutive numbers is called the common ratio,r:
[tex]r=\frac{a_n}{a_{n-1}}[/tex]
Given that f(3)=32 and f(9)=72, we can find the common ratio as below:
[tex]r=\frac{a_n}{a_{n-1}}\\\\\therefore \frac{f(9)}{f(3)}=r^6\\\\\frac{72}{32}=r^6\\\\r^6=2.25\\\\r=2.25^{1/6}[/tex]
#We substitute and use the same formula to find the nth term:
[tex]a_n=ar^{n-1}[/tex]
let f(3) be a(the first term):
[tex]a_n=ar^{n-1}\\\\a_{16}=32(2.25^{1/6})^{16-3-1}\\\\a_{16}=32(2.25^{1/6})^{12}\\\\\\=162[/tex]
Hence, f(16)=162
