Answer:
Hi there!
The correct answer is: 20
Step-by-step explanation:
knowing this a right triangle you can solve this problem in two ways
Method One: Pythagorean Theorem
a^2 + b^2 = c^2 then plug in the values
(12)^2 + (16)^2 = c^2 this will come out to be 400 = c^2
square root both sides and you get c = 20
Method Two: Pythagorean Identities
if you ever learned the Pythagorean identity 3,4,5
this triangle is indeed a 3,4,5 triangle it's just that each side is multiplied by the factor 4
so in this case since you know the missing side should be 5 you just multiply 5 by 4 and you get 20
The first one is 6 gallons and the other one you can’t because if josh gets 3 gallons of gas he’s going to have to pay $8.25 but if he gets 4 gallons he’s going to have to pay $11
To find the percent increase, you will first find the difference in price for the peak season economy and the regular economy price.
$526.3-$440.8=$85.50
Then divide the difference by the beginning price(economy).
85.50/440.8= 0.19
The percent increase is approximately 19%.
Expand it first. -2(x+3)= -2x-6
-2x-6 = 10
-2x = 10+6
-2x = 16
-x = -8
x = 8
Using the fixed point concept, it is found that f(x) has 3 real fixed points.
-------------------------------
The fixed points of a function f(x) are the values of x for which:
In this question:
Then
Applying subtraction of perfect squares, 
Again, 
Then
There are 3 real fixed points, 
and
