Answer:

$(-5,-1)$

Step-by-step explanation:

We have been given the coordinates of a point and we are asked to find the coordinates of he point after a counterclockwise rotation of 90º about the origin.

We know that after rotating a point 90 degree counter-clockwise about the origin, the x and y-coordinates changes places with each other and x-coordinate of new point becomes the negative of y-coordinate.

$(x,y)\rightarrow (-y,x)$

Applying the rotation rule the coordinates of new point would be:

$(-1,5)\rightarrow (-5,-1)$

Therefore, the required coordinates of the given point after a counterclockwise rotation of 90º about the origin would be $(-5,-1)$ .

She would have 37 pigs and ducks. You said at the beginning of your question how many she has, but there wouldn't be116 legs if that's right. There would be 222 legs.

At the farmers market two pounds of peaches cost 4.20 how much would five pounds cost show work

Marizza181 [45]

Hey!

You can make a proportion:

$\frac{2}{\$ 4.20} = \frac{5}{x}$

Cross multiply

$\$ 4.20 \times 5 = \$ 21$

Divide by 2

$\$ 21 \div 2 = \$ 10.5$

5 pounds would cost $10.50

Good luck and hope this helps! :)

Answer:

Below is the complete step-by-step explanation.

Step-by-step explanation:

Given the row of numbers

25060 12315 86244 97348 36173 32710 80033 16160

Taking 25060 as seed

Total random numbers to be generates = 12

Range of random number generators

Minimum value = 01
Maximum Value = 99

Seed the number (25060) into your calculator. 25060 ➡️ rand

So, the operation randInt(1,99,12) will generate the following 12 random numbers between 01 and 99.
