Which of the following scale factors would produce a larger image? A. 2/3
B. 1-1-2
C1/2
D. 1

Correct option: B.

Step-by-step explanation:

Scale factors

For a scale factor to produce enlargements or increased results, it must have a value greater than 1.

For example, a scale factor of 2 applied to 15 produces a value of 30

A scale of 1.4 applied to 120 produces a value of 168

A scale of 0.9 applied to 80 gives 72. In this case, a scale factor of less than 1 produces a smaller value as a result.

From the options shown, we have to select the only one whose value is greater than 1.

A. 2/3 = 0.67. Not correct

B. 1 1/2=1.5. Correct

C. 1/2 = 0.5. Not correct

D. 1. Not correct

Correct option: B.

40% off the regular price is the correct answer.

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
