Answer:
The difference in area of the two pizzas is 113.14 inch².
Step-by-step explanation:
Martin ordered a pizza with a 16 inch diameter and Ricky ordered a pizza with a 20 inch diameter.
We have to calculate the approximate difference in area of the two pizzas.
Ara of pizza ordered by Martin =
=
Area of pizza ordered by Ricky =
Difference in area =
=
= 113.14 inch²
The difference in area of the two pizzas is 113.14 inch².

Answer:
Step-by-step explanation:
Problem One
19 + 2*ln(x) = 25 Subtract 19 from both sides
19 - 19 + 2ln(x) = 25 - 19 Combine
2* ln(x) = 6 Divide by 2
ln(x) = 3 Take the inverse log
e^(ln(x)) = e^3 Reduce
x = 20.09
Problem 2
Getting this to graph in Desmos can be a bit of trouble. The correct format is y = abs(x^2 - 3x + 1). Knowing about abs and getting the quadratic to work are two separate [and difficult] problems.
The graph for this is below.
The answers (according to Desmos) are (2,1) and (3.4, 2.4). I think you should include D but that is a matter of opinion. I think it's a typo. Whoever made the question up may actually get that answer.
