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.

Which statement could describe the graph?
A. After driving for 3 hours, Will stopped for lunch.
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.

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.

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).

For the following exercises, use the table of values that represent points on the graph of a quadratic function. By determining the vertex and axis of symmetry, find the general form of the equation of the quadratic function.
Answer:
y = x² + 2x + 1
Step-by-step explanation:
Same y value at x = -2 & x = 0
So line of symmetry is at:
x = (-2+0)/2
x = -1
Vertex: (-1,0)
y = a(x - -1)² + 0
y = a(x + 1)²
At x = 1, y = 4
4 = a(1 + 1)²
4 = 4a
a = 1
y = (x + 1)²
y = x² + 2x + 1
The general form of the equation of the quadratic function is x² + 2x + 1
The formula expressing the equation of the quadratic function will be expressed as:
y = a(x -h)² + k
From the table shown, we can see that the y-values are the same at where x = -2 and 0
Get the line of symmetry:
[tex]x =\frac{-2+0}{2}\\x=\frac{-2}{2} \\x=-1[/tex]
We can see that when x = -1, y = 0. Hence the vertex will be at (-1, 0)
h = -1
k = 0
Substitute into the formula y = a(x -h)² + k
y = a(x -(-1))² + 0
y = a(x+1)²
From the table at where x = 1, y = 4. On substituting to get "a" we have:
4 = a(1+1)²
4 = 4a
a = 1
Get the required quadratic function by substituting the parameters into the general formula as shown:
y = a(x -h)² + k
y = 1(x +1)² + 0
y = (x+1)²
y = (x+1) (x+1)
y = x² + x +x + 1
y = x² + 2x + 1
Hence the general form of the equation of the quadratic function is x² + 2x + 1

The cruising speed of the bullet train will be at least 170 miles per hour. Use s to represent the train's cruising speed (in miles per hour). Write an inequality to represent the situation
Answer:
s ≥ 170
Step-by-step explanation:
The problem raises the following statement: "The cruising speed of the bullet train will be at least 170 miles per hour"
Which means that the train has a speed of 170 miles for now or higher, knowing this we can pose the inequality.
Knowing that "s" is the train's cruising speed (in miles per hour), we have to:
s ≥ 170
This would be the inequality that the statement represents.
The inequality representing the bullet train's cruising speed being at least 170 miles per hour is s ≥ 170.
The situation described involves finding an inequality for the train's cruising speed. To represent the train's cruising speed in miles per hour, we use the variable s.
Given that the cruising speed of the bullet train will be at least 170 miles per hour, we need an inequality that expresses this condition.
The inequality is:
s ≥ 170
This means that the cruising speed s can be 170 miles per hour or higher.
