So, we know that 40 hours is $390 and 4 * 10 = 40, therefore, we just have to divide $390 by 4 to get $97.5, meaning that Zoe made $97.5 in 10 hours of work.
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 <em>vertical expansion</em> (not shrink) of F(x) — by a factor of 2.
_____
<em>Additional comment</em>
The equation g(x) could be considered to be ...
g(x) = F(x·√2)
in which case g(x) could be interpreted as a <em>horizontal shrink</em> by a factor of (√2)/2. Squeezing a parabola horizontally has the same effect on its appearance as stretching it vertically.
Answer:
Interest rate is 5.25% a year.
Step-by-step explanation:
r = (1/54)((22252.5/18000) - 1) = 0.004375
r = 0.004375
Convert decimal to percentage
R = 0.004375 * 100 = 0.4375%/month
Calculate annual rate
0.4375%/month × 12 months/year = 5.25% per year.
