the product gives the coordinates of two points on line AB that has been rotated 90 degrees counterclockwise about the origin. name the coordinates of A’ and B’.
Answers
Answer 1
Answer:
Since you haven't provided the coordinates of A and B, I cannot give an exact answer. However, I will help you with the concept.
Rotation 90° about the origin will result in the following: (x,y) ..........> (-y,x)
Therefore, you have to multiply the y value by -1 and then flip the x and y.
Examples: (2,9) ..........> Rotation 90° about the origin .........> (-9,2) (-3,4) .........> Rotation 90° about the origin .........> (-4,-3) (-1,0) ..........> Rotation 90° about the origin .........> (0,-1) (8,-6) ..........> Rotation 90° about the origin .........> (6,8)
Solve using the quadratic formula show all work 2n2 - 7n - 3 = 0
Answers
Quadratic formula = ( -b +/- square root of b^2-4ac ) / 2a
In this case, a=2, b= -7 and c= -3
So:
(7 +/- square root of (-7)^2 - 4*2*(-3) ) / 2*2
= (7 +/- square root of 49 + 24 ) / 4
= 7 +/- square root of 73 / 4
Using a calculator, you end up with the answers: 3.886 and -0.386
the answer is -1 i think
In the next 3 hours, the crew was digging at a rate of -2.5 feet each hour. During the last 2 hours, the crew slowed to a rate of -2.25 feet each hour. What number would they record for the location after the 8 hours?
Answers
To calculate the location after 8 hours of digging at different rates, you can sum up the distances they dug during each time period.
In the first 3 hours, they dug at a rate of -2.5 feet per hour, so they dug a total of: 3 hours * (-2.5 feet/hour) = -7.5 feet
In the next 2 hours, they dug at a rate of -2.25 feet per hour, so they dug a total of: 2 hours * (-2.25 feet/hour) = -4.5 feet
Now, add these two distances together to find their location after 8 hours: -7.5 feet + (-4.5 feet) = -12 feet
So, they would record a location of -12 feet after 8 hours of digging.

What is the KE of a 1 kg ball traveling at 20 meters per second?
Answers
The easiest way to find that answer is to look at the solution that I just gave you for the same ball traveling at 30 M/Sec, and just substitute 20 in place of 30 in that solution.
Use the substitution method to solve the system of equations.y = -4x 8x - y = 6 A (1/2,-4 B.(1/2,-2 C. (2,-8) D. (1,-4)
