The coordinate after a rotation of 180° counterclockwise about the origin is (0, 9).
What is rotation?Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.
The given coordinate is (0, -9).
Rotation rule:
Rotating a point that has the coordinates (x,y) 180° about the origin in a clockwise or counterclockwise direction, produces a point that has the coordinates (-x,-y).
Now, (0, -9) → (0, -(-9))
(0, -9) → (0, 9)
Therefore, the coordinate after a rotation of 180° counterclockwise about the origin is (0, 9).

3. State if each of the labeled points is a local min, max or
neither.
Is the function even or odd? Explain.
Please explain right I’m giving 100 points in this that means the 2 people Who answers this will get 50 each
Answer:
(5, 7) is a local maximumFunction is oddStep-by-step explanation:
As we see on the graph:
point (1,2) on the falling section,point (3,3) on the rising section,point (5,7) on the top section,... of the local intervals. therefore only point (5, 7) is a local maximum.
Absolute minimum is - oo, absolute maximum is + oo
A function is even if its graph is symmetric with respect to the y-axis. A function is odd if its graph is symmetric with respect to the origin.The given function is odd as per above definition
Cheyenne bought 60 tickets for rides at an amusement park. Each ride costs 4 tickets, and Cheyenne has been on x rides so far. Write an expression is equivalent to the number of tickets that Cheyenne has left?
Answer:
x=number of rides taken
y=number of tickets left
60=4(x)+y

if x:y=3:5 find the ratio 3×+4y:8x +5y
Answer:
29: 49
Step-by-step explanation:
Since x:y= 3:5,
[tex] \frac{x}{y} = \frac{3}{5}[/tex]
Cross multiply:
[tex]5x = 3y[/tex]
Divide by 5 on both sides:
[tex]x = \frac{3}{5} y[/tex]
[tex] \frac{3x + 4y}{8x + 5y} \\ = \frac{3( \frac{3}{5}y) + 4y }{8( \frac{3}{5}y) + 5y } \\ = \frac{ \frac{9}{5}y + 4y }{ \frac{24}{5}y + 5y } \\ = \frac{9y + 5(4y)}{24y + 5(5y)} \\ = \frac{9y + 20y}{24y + 25y} \\ = \frac{29y}{49y} \\ = \frac{29}{49} [/tex]
Thus, 3x+4y: 8x+5y= 29: 49.
which line is parallel to one whose equation is y=5x+7

On a Saturday, Saul can cut 4 lawns in 6 hours. If Mitch can mow lawns at the same rate, how long will it take him to mow 9 lawns?
12 hours
12 3/4 hours
6 hours
13 1/2 hours
Answer:
13 1/2 is your answer.
Step-by-step explanation:
With the same ratio the time taken Mitch to mow 9 lawns will be 13 + 1/2 thus option (D) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
Saul can cut 4 lawns in 6 hours.
The ratio of hours to lawns will be as,
6/4
Suppose the time taken to mow 9 lawns to Mitch is x hours.
The ratio of hours to lawns will be as
x/9
Since the rate is the same thus ratio must be the same.
x/9 = 6/4
x = 6/4 x 9
x = 13.5 = 13 + 1/2
Hence"With the same ratio, the time taken Mitch to mow 9 lawns will be 13 + 1/2".

The clock shows the time that Ron left his home in the morning. He came home 7
hours and 35 minutes later. What time did Ron come home?
Answer: 14:35 hrs
Step-by-step explanation:
Missing time that Ron left was 07:00 hrs
Ron left the house at 07:00 hrs. If he arrived back to the house 7 hours and 35 minutes later, you can find out what time he arrived by simply adding the time he left to the time he stayed outside:
= 7 + 7hrs 35 minutes
= 14 hrs 35 minutes
= 14:35 hrs

Given: f(1) = 3x– 7, 9(x) = 2x^2 – 3x +1, h(x) = 4x + 1, k(x) = –x^2+3
Find: (h o g) (x)
Answer:
(h o g) (x) = h(g(x))
Step-by-step explanation:
(h o g) (x) = h(g(x)) = 4(g(x))+1 = 4(2x^2 -3x + 1 ) + 1
= 4*2x^2 - 4*3x + 4*1 + 1
= 8x^2 - 12x + 4 + 1
= 8x^2 - 12x + 5
