Please answer this these are all the points i got left XD

Kazeer [188]

Answer is choice B

The ratio of the sides (first to the second) is 11/9 since we divide 22/18 and reduce that fraction

Once we know the scale factor is 11/9, we square it to get (11/9)^2 = 121/81 which is the ratio of the first area to the second area

Everbank Field, home of the Jacksonville Jaguars, is capable of seating 76,867 fans. The revenue for a particular game can be mo

Andrei [34K]

The domain of the function is all the values from which the functio can be mapped: here it's between 0 and <span>76,867 -depending on how many people come

</span> $0 \leq x\geq 76867$

The range is all the values that the function can have.So here it's from 0, when noone is coming, to 76867*161=12377036

$0 \leq y\geq 12377036$

The radius of a sphere is increasing at a rate of 2 mm/s. How fast is the volume increasing when the diameter is 80 mm? Evaluate

Komok [63]

Well, if it is increasing at a fixed rate of 2 mm/s, then the volume would still be increasing at a rate of 2 mm/s when the diameter is 80 mm, if I understand your question correctly.
