what would (9, 10) be after a rotation 270 degrees counterclockwise around the origin?
The new coordinates of the point (9, 10) after a rotation of 270 degrees counter-clockwise around the origin are (10, -9).
The coordinates of the point are (9, 10). We perform a transformation on the point. The type of transformation performed is rotation. The rotation is done at an angle of 270 degrees in a counter-clockwise direction around the origin. First of all, we need to convert the angle of rotation from degrees to radians. The angle θ is 270*(π/180) = 3π/2. Let the original coordinates be denoted by (a, b) and the coordinates after rotation be (x, y). We can write the following equations using the theory of rotation.
x = a×cos(θ) - b×sin(θ) = 9×cos(3π/2) - 10×sin(3π/2) = 0 - 10(-1) = 10
y = b×cos(θ) + a×sin(θ) = 10×cos(3π/2) + 9×sin(3π/2) = 0 + 9(-1) = -9

Two consecutive terms in an ARITHMETIC sequence are given. Find the recursive function.
An arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
The recursive formula have the following format:

From the text, we know that

b. Lynn is traveling in Mexico. She exchanges $200 for pesos. If the exchange rate is 19.29 pesos per US dollar, how many pesos should she expect to receive from the exchange pesos
The expected pesos after exchange are 3858 , we can find out by using the concept of exchange rate.
How to calculate currency after exchange rate?
Multiplying the money you have budgeted by the exchange rate .
for example,
If "a" is the money in one currency , you have
"b " is the exchange rate
"c" is the expected money in another currency after exchange.
So, a * b = c
Here, a= $200
b=19.29

Use your answers from #1 and #2 to find the length of each arc between gondola cars. Use 3.14 for pi and round to the nearest hundredth. You must write out all the numbers you are multiplying together, meaning, show your work for full credit.
We have a SkyWheel.
We know that the angle between the gondolas is 360/41 = 8.78°.
The radius of the wheel is 181/2 = 90.5.
We know have to calculate the length of the arc between gondolas.
The length of the arc L can be calculated using proportions: the length of the arc is to the angle between gondolas as the total circumference of the wheel is to 2*pi (or 360°).
We can express this as:
[tex]\frac{L}{\theta}=\frac{C}{2\pi}[/tex]If we rearrange, we can solve for L:
[tex]\begin{gathered} \frac{L}{\theta}=\frac{C}{2\pi} \\ \frac{L}{\theta}=\frac{2\pi r}{2\pi} \\ \frac{L}{\theta}=r \\ L=\theta\cdot r=(\frac{2\pi}{41})\cdot90.5=(\frac{2\cdot3.14}{41})\cdot90.5=13.86ft \end{gathered}[/tex]NOTE: we have to express the angle theta (that is the angle between the gondolas) in radians when we want to calculate a length. That is why this angle is expressed as the total angle of the circle (2*pi) divided the 41 gondolas.
If we use 8.78°, we should express it as:
[tex]L=\theta\cdot r=8.78\degree\cdot(\frac{2\pi}{360\degree})\cdot90.5ft=13.86ft[/tex]With the factor 2pi/360 we are converting the angle in degrees into radians in order to calculate the length.
Answer: the length of the arc between gondolas is 13.86 ft.

Well, by looking at the x factors, none of them repeat so it is a function. To determine if it's linear, you can look to see if the change is consistent. From 0 to 2 is +2, and from 10 to 6 is -4. From 2 to 4 is +2, but from 6 to 4 is -2. Since it doesn't go down the table at a set rate, it isn't linear. So, it is a function, but not a linear function

The amount at the end of 30 days, when interest compounded daily is found as $982.53.
What is referred as the compound interest?Compound interest is investment determined on the preliminary principal plus all previous periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest could be compounded at any time, from continuously to everyday to annually.The formula for calculating the compound interest is;
A = P(1 + r/100n)∧nt
Where,
CI = compound interestP = principal amount = $980r = rate of interest = 3.1%n = number of time interest compounded = 30 dayst = time in years = 1 months; 1/12 year.A = amount after given time.Now put the values in the formula.

Two machines worked on a car. The first mechanic worked for 20 hours, and the second mechanic worked for 15 hours. Together they charge a total of $2250. What was the rate charged per hour by each mechanic if the sum of the two rates was $125 per hour?
Solution:
Let's make,
mechanic #1's rate = x
mechanic #2's rate = y
Note that their rate is dollars per hour.
Now, mechanic #1 worked for 20 hours. Then, we get the following equation:
20x = money earned by mechanic #1
On the other hand, mechanic #2 worked for 15 hours. Then, we get the following equation:
15y = money earned by mechanic #2
together they charged a total of $2250. So the amount of money earned by both mechanics is:
20x + 15y = 2250 EQUATION 1
On the other hand, the sum of the two rates was:
x + y = 125 EQUATION 2
From the equation, if we solve for x, we get:
x = 125-y EQUATION 3
plug (125-y) in for "x" in equation 1 to get everything in terms of one variable:
20(125-y)+15y = 2250
this is equivalent to
2500-20y +15y = 2250
this is equivalent to
2500 -5y = 2250
this is equivalent to
-5y = 2250 -2500
this is equivalent to:
-5y = -250
or
5y = 250
solving for y, we get:
[tex]y\text{ =}\frac{250}{5}=50[/tex]now, replacing this into equation 3, we get:
x = 125-y = 125 - (50) = 75
so that, we can conclude that the correct answer is:
mechanic #1 charged 75 $/hr
mechanic #2 charged 50 $/hr

two angles are supplementary. One angle measures 12 degrees less than 3 times the other. find the measure of each angle
Angle 1 = A
Angle 2 = B
They are supplementary, that means that they add 180 degrees, then: A + B = 180
One angle measures 12 degrees less than 3 times the other, tahn means: A - 12 = 3B
Equation 1: A + B = 180
Equation 2: A - 12 = 3B
Solving for A in equation 1:
A + B = 180
A = 180 - B
Using this value into equation 2, and solving for B:
A - 12 = 3B
(180 - B) - 12 = 3B
180 - B - 12 = 3B
168 = 3B + B = 4B
4B = 168
B = 168/4 = 42
B = 42
Using the expression we found for A:
A = 180 - B = 180 - 42 = 138
A = 138

Determine the present value P that must be invested to have the future A at simple interest rate r after time t A= $3000.00 r=15,0% t= 9 months Round up to nearest cent as needed
Answer:
$2696.63
Explanation:
The future value A and the present value P are related by the following equation
A = P(1 + rt)
Where r is the interest rate and t is the time.
Now, we need to convert 9 months to years as follows
9 months x 1 year / 12 months = 0.75 years
Then, replacing A = 3000, r = 15% = 0.15 and t = 0.75, we get:
3000 = P(1 + 0.15(0.75))
3000 = P(1 + 0.1125)
3000 = P(1.1125)
Now, we can solve for P
P = 3000/1.1125
P = 2696.63
Therefore, the present value is $2696.63
