end ordered pair.
When segment J K is dilated with a scale factor negative 4, what are the coordinates of J prime and K prime?

options:

J prime begin ordered pair negative 12 comma 24 end ordered pair and K prime begin ordered pair 12 comma negative 8 end ordered pair

J primebegin ordered pair negative 1 comma negative 10 end ordered pair and K prime begin ordered pair negative 7 comma negative 2 end ordered pair

J prime begin ordered pair negative fraction 3 over 4 end fraction comma 3 over 2 end ordered pair and K prime begin ordered pair 3 over 4 comma negative 1 half end ordered pair

J' is at (-12, 24) and K' is at (12, -8).

Multiply both the x- and y-coordinates of J by -4; then do the same with the coordinates of K.

The volume of a cylindrical bucket is 4019.2 cubic inches. Find the height of the bucket if the base area is 200.96 sq. Inches?
natita [175]

Answer:

20

Step-by-step explanation:

Formula

V = B * h

Givens

B = 200.96 square inches

V = 4019.2 cubic inches

Solution

4019.2 = 200.96 * h         Divide by 200.96

4019.2/200.96 = h

h = 20 inches

Choose the quadratic equation that has a leading coefficient of 1 and solutions 3 and -2.
ss7ja [257]

Answer:

Option D x^{2} -x-6=0

Step-by-step explanation:

Verify each quadratic equation

case A) we have

x^{2} +x+6=0

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

(3)^{2} +(3)+6=0

18=0 ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case B) we have

x^{2} -x-5=0

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

(3)^{2} -(3)-5=0

1=0 ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case C) we have

x^{2} +x+5=0

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

(3)^{2} +(3)+5=0

17=0 ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case D) we have

x^{2} -x-6=0

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

(3)^{2} -(3)-6=0

0=0 ----> is true

therefore

x=3 is a solution of the quadratic equation

For x=-2

(-2)^{2} -(-2)-6=0

4+2-6=0

0=0 ----> is true

therefore

x=-2 is a solution of the quadratic equation
