What is the scale factor of dilation?
1 over 2
1 over 3
1 over 4
1 over 5

 1 over 3

Step-by-step explanation:

The dilation is a transformation which produces similar figures.

The scale factor dilation is the ratio of the corresponding coordinates of the image and the pre-image.

In the given graph triangle PQR is dilated to form triangle P'Q'R', then the scale factor to the dilation is given by :-

Hence, the  scale factor of dilation =  1 over 3

40 x 50 = 2000

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
