Answer:

$\frac{p}{q} \div \frac{r}{s} = \frac{ps}{qr}$

Step-by-step explanation:

Given

$\frac{p}{q} \div \frac{r}{s} =$

Required

Solve

$\frac{p}{q} \div \frac{r}{s} =$

Turn division to multiplication

$\frac{p}{q} \div \frac{r}{s} = \frac{p}{q} * \frac{s}{r}$

$\frac{p}{q} \div \frac{r}{s} = \frac{ps}{qr}$

Refering to the equation, tell how

Ugo [173]

Answer:

the scale factor is the vertical expansion factor.

Step-by-step explanation:

The scale factor of 2 in

g(x) = 2·F(x)

means g(x) is a vertical expansion (not shrink) of F(x) — by a factor of 2.

_____

Additional comment

The equation g(x) could be considered to be ...

g(x) = F(x·√2)

in which case g(x) could be interpreted as a horizontal shrink by a factor of (√2)/2. Squeezing a parabola horizontally has the same effect on its appearance as stretching it vertically.

4 entries are 24 so one entry is 24/4 = 6

so 7 friends pay 6*7 = 42
