Answer:
C
Step-by-step explanation:
Because that is the only graph that makes the relationship between the 2 propportional.
at 00 hours she makes 0 dollars
at 1 hour she makes 20 dollars
at 2 hours she makes 40
at 3 hours she makes 60
at 4 hours she makes 80
at 5 hours she mkes 100
at 6 hours she makes 120
and so on...
Answer:3, 25
Step-by-step explanation:
The seconds should be the x-axis and the height is y axis. Also thinking about how a kicked ball makes an arch, the max is 25, and the mid point between 0 and 6 is 3.
Answer:
The required ratio is 9 : 61
Step-by-step explanation:
Given,
$72 for 488 photos,
That is, the price of 488 photos = 72 dollars,
So, the ratio of price of photos and number of photos = 
∵ HCF(72, 488) = 8,
Thus, the ratio of price of photos and number of photos = 
= 
Relative extrema occur where the derivative is zero (at least for your polynomial function).
So taking the derivative we get
<span>20<span>x3</span>−3<span>x2</span>+6=0

This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
