Write and solve an equation of ratios:
1/4 pizza $5
------------- = -----------
x $8
2 pizza
Then (1/4)($8) = ($5)x, or x = --------------- (that's 2/5 of a whole pizza).

A flat circular plate has the shape of the region x 2 + y 2 ≤ 1. points on the plate have temperature t(x, y) = x 2 + 2y 2 − x. find the temperatures of the hottest and coldest points of the plate
Answer:
Step-by-step explanation:
15 - x > 0
-x > -15
x < 15
if x < 15 15-x
if x = 15 0
if x > 15 x-15
Answer: A (t) = 24500 (1+0.03)^t
Step-by-step explanation:
Hi, to answer this question we have to write a growth function:
A = P (1+r) ^t
Where:
A = amount after growth
P = initial amount
r = growth rate (in this case is yearly, since she gets a 3% raise each year)
t = years
Replacing with the values given:
The growth rate must be in decimal form (divided by 100)
A (t) = 24500 (1+3/100)^t
A (t) = 24500 (1+0.03)^t
