A parachutist's rate during a free fall reaches 162 kilometers per hour. What is this rate in meters per second? At this rate, how many meters will the parachutist fall during 10 seconds of free fall? Do not round your answers.
rate: (m/s)
distance fallen in 10 seconds:
Step-by-step explanation:
162 kilometers = 162000 meters
1 hour = 3600 seconds.
162,000 meters/3600 seconds=45 meters/second=45 m/s
45*10=450
Suppose P, Q, and R are points in the plane such that PQ=1.8, PR=8.2, and angle PQR=90 degrees. What is the area of triangle PQR$?
Answer:
7.2 sq units
Step-by-step explanation:
Seeing as this is a right triangle, and the hypotenuse and one leg is given, you can use the pythagorean formula to get the third side ([tex]\sqrt{8.2^2 - 1.8^2}[/tex]). Now that we have this leg, we can multiply this by 1.8, then divide it by two (area of triangle).

What is the solution to this inequality?
−4x − 8 > −20
Question 7 options:
x > −3
x < −3
x > 3
x <3
Answer:
[tex]\boxed{\sf{D. \quad x < 3}}[/tex]Step-by-step explanation:
It is necessary to isolate the term of x from one side of an inequality to find its solution.
-4x-8>-20First, add by 8 from both sides.
[tex]\sf{-4x-8+8 > -20+8}[/tex]
Solve.
-20+8=-12
Rewrite the problem down.
[tex]\sf{-4x > -12}[/tex]
Multiply by -1 from both sides.
(-4x)(-1)<(-12)(-1)
Solve.
Multiply the numbers from left to right.
(-12)(-1)=12
4x<12
Divide by 4 from both sides.
4x/4<12/4
Solve.
Divide the numbers from left to right.
12/4=3
x<3
Therefore, the correct answer is D. x<3 (last option).I hope this helps you! Let me know if my answer is wrong or not.
Answer:
Option D.
Why is this the case, though?These equations prove it true.
[tex]-4 * 2 - 8 = -16 > -20[/tex]
[tex]-4 * 1 - 8 = -12 > -20[/tex]
The only reason these two equations are correct, is because on the number line it shows: Any negative number further to the right than the last negative number is greater than that number.

B The large cat's meal tastes more like tuna fish.
Step-by-step explanation:
Max has a piece of luggage that weighs 23.4 pounds. Convert this weight into kilograms
Answer:
First, we must know that;
1 pound is roughly about 2.2 kilograms.Given this, multiply the pounds you are given by 2.2 kilograms since 2.2 kilograms make up one pound.
23.4(2.2)
= 51.48 kilograms
23.4 = pounds
2.2 = kilograms (that make up one single pound)

Which is a solution to the linear inequality 2x-3y>6
A. (3,0)
B. (-3,1)
C. (3,-1)
Answer:
C ( 3,-1) is a solution
Step-by-step explanation:
2x-3y>6
Let x = 3
2(3) -3y >6
6 - 3y>6
Subtract 6
-3y >0
Divide by -3
-3y/-3 < 0/-3
y < 0
If x = 3 y must be less than 0
C ( 3,-1) is a solution

Answer:
Here you are my good sir!
Step-by-step explanation:
In a translation transformation all the points in the object are removed in a straight line in the same direction. The size, the shape and the orientation of the image are the same as that of the original object. Same orientation means that the object and imageare facing the same direction. Example: We describe a translation in terms of the number of units moved to the right or left and thenumber of units moved up or down. Example: Move the object 2 units to the right and 4 units up.
A scatter plot is made comparing x, the number of hours since midnight, with y, the number of lights turned on in a house. What would a point at (7,8) on the scatter plot mean?
Answer:
7 hours since midnight and 8 lights turned on.
Step-by-step explanation:
(x,y) so 7 is the x and 8 is the y.
Write a statement that correctly describes the relationship between these two sequences: 2, 4, 6, 8, 10 and 1, 2, 3, 4, 5.
Answer:
There is a positive correlation happening.
Step-by-step explanation:
A positive correlation happens when both of the sequences are going up. In the first sequence, the terms go up by 2. In the second one, the terms go up by 1. While the do not have the same common difference, the two sequences still increase. This makes the relationship a positive one.

Find the average rate of change from x=4 to x=10 for the equation y=2x-3
Answer:
2
Step-by-step explanation:
The average rate of change of the equation during the interval 4 ≤ x ≤ 10
can be represented in this expression if f(x) is substituted for y:
[tex]\dfrac{f(10)-f(4)}{10-4}[/tex]
[tex]=\dfrac{17-5}{6}[/tex]
[tex]=\dfrac{12}{6}[/tex]
[tex]=2[/tex]
So, the average rate of change (AOC) is 2.
You also could just figure this out by looking at the slope. Since this is a linear equation, the AOC over any interval will always be the same as the slope, since the slope is constant.
Please help the camera quality is really bad tho so hopefully you can read it.
Step-by-step explanation:
To find the quadrent a coordinate pair is in:
1. look at the "x" value in the (x,y) pair
2. if its negetive go leftward and if its positive go rightward
3. once you have moved to the respective x location do the same thing with the y coordinate in the (x,y) pair
4. up is positive for y and down is negitive.
for example (3,3) would be 3 to the right and 3 up so its in the top right quadrent
(-3,-3) would be 3 left and 3 down so its in the bottom left
A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a 15% discount on your purchase that day. If the card is an odd number greater than 6, you get a 30% discount. Otherwise, you get a 20% discount. The table shows the results of 400 customers. What is the relative frequency for each discount? If the manager of the store wants approximately half of the customers to receive the 20% discount, does this seem like an appropriate method? Explain.
Answer:
No
Step-by-step explanation:
It is not an appropriate method because if you add all of the people that got 1, 3, and 5 together to get all the people that got the 20% discount, you get 140/400 people, and in order for it to be half there would have to be, or close enough to, a total of 200/400 people.
15% discount = 185/400 or 46.25%
20% discount = 140/400 or 35%
30% discount = 75/400 or 18.75%

help me do examples for a function and a non function
Answer:
{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}
Step-by-step explanation:
you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)
an example of a function would be {(1,2) (3,4) (5,6)}
an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.
using this, another example of a function would be {(1,2) (3,2) (5,2)}
an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.

Answer:
22 11/16 or 22.68
Step-by-step explanation:
Turn the mixed numbers to fractions
[tex]\frac{11}{2} *\frac{33}{8}[/tex]
Then multiply both Numerators
11 x 33=363
Also do the same to the Denominators
2 x 8=16
You get [tex]\frac{363}{16}[/tex]
Simplify and it becomes 22 11/16 or 22.68
Two expressions are shown below

Step-by-step explanation:
(You can do this differently, but I chose to do it like this)
First, convert the 1816 kilograms to pounds.
1816 kilograms = 4003.595 pounds
Then, we can divide 4003.595 pounds by 160 to figure out how many 160-pound people the balcony can hold.
4003.595 ÷ 160 ≈ 25.02
If the balcony holds 26 people, it will collapse, so the answer must be 25.
