Do,h = (7,9) —> (14,18) the scale factor is

option B

2

Step-by-step explanation:

Given in the question

DO,h(7, 9) → (14, 18)

Formula to use

distance formula = √((7-0)²+(9-0)²) = √(7²+9²) = √130

distance formula = √((14-0)²+(18-0)²) = √(14²+18²) = 2√130

Scale factor

√130 = 2√130

He has to pay $ 2.76 for the yogurt.

Step-by-step explanation:

Given data

Cost of each ounce = $ 0.24

Vanilla yogurt = 6.5 ounces

Strawberry yogurt = 5 ounces

Now Total cost of yogurt = 11.5 × 0.24

Now Total cost of yogurt = $ 2.76

Therefore he has to pay $ 2.76 for the  yogurt.
