First on is linear, second is exponential, third is exponential and the last is linear
All problems that are linear increase by a constant rate, ones that increase exponentially increase by a percentage or decimal
Answer:
A
Step-by-step explanation:
he discount? Round the answer to two decimal places.
(b) A customer paid $16.99 for a shirt that normally sells for $19.99. What percent
discount did the customer receive? Round your answer to the nearest percent.
(c) A customer and a salesperson are arguing about a promotion and a coupon
applied after the promotional discount. The promotion is a 20% discount on all items
in the store. The coupon is an additional 10% off of the order. The customer claims
the 20% discount should be made before the 10% discount. The salesperson claims
Vertex is directly in middle of directix and focus
distance from 8 to -8 is 16
16/2=8
so 8 below focus (since 8>-8) is the point (0,0
vertex is (0,0)
nice
it opens up because focus is above directix
also it goes up down so
4p(y-k)=(x-h)^2
(h,k) is veretx
we got that (h,k) is (0,0)
and p is distance from vertex to focus which is 8
so
4(8)(y-0)=(x-0)^2
32y=x^2
y=(1/32)x^2
