Answer: 59
Step-by-step explanation:
The center angles are each 90, Each triangle adds to 180 and is the same as the other three that it forms the rhombus with. If the outside angles are 31 degrees then the last angle ( ADE ) must be 59 degrees
Part A:
Yes this is a function of x. Specifically the function is f(x) = x^2
The inputs (x) are squared to get the outputs (y).
For example,
f(x) = x^2
f(-3) = (-3)^2 <<--- input is x = -3
f(-3) = 9 <<--- output is 9
The pair of values -3 and 9 are shown in the table (column on the very right side)
The fact that each input leads to exactly one output is what makes this a function. If we had an input lead to multiple outputs, then it wouldn't be a function.
=============================================================
Part B
Replace every x with 150 and then use the order of operations PEMDAS to simplify
f(x) = 20+3x
f(x) = 20+3*x
f(150) = 20+3*150 <<--- x has been replaced with 150
f(150) = 20+300
f(150) = 320
So the value of f(150) is 320
The input is 20
The output is 320
x is the number of hours
y or f(x) is the total cost
So this means f(150) = 320 represents the idea that 150 hours of renting the rowboat leads to a total cost of $320

Answer: False</h3>
Here's a counter example to prove the statement to be incorrect
first number = 1
second number = -2
sum = 1 + (-2) = -1
difference = 1 - (-2) = 1 + 2 = 3
We see that the difference (3) is not smaller than the sum (-1)
