Answer:
The sum of interior angles of a regular shape is found by doing no. of sides - 2 and times this by 180
8-2 =6
6x 180= 1080
then divide by 8 to find each angle
1080/8 = 135
Answer:
Step-by-step explanation:
1. Three million, two hundred ninety eight thousand, seventy six
2. 50,003,087
50,000,000+3000+87
3. 60,400,239
Answer:X=125 ,Move variable to the left by adding its opposite to both sides and then Eliminate the opposites. Your welcome
B as -$39 as he owes his mom that, then +30 as he earned it and then since he lent his sister $21 that’s $21 less so -$39+$30-$21
The correct answer is option D. Which is the even function is f (x) = x⁴.
<h3>What is an even function?</h3>
The function in which when the sign of the input variable is changed the output remains the same is called the even function. Mathematically we can write it as f(x) = f(-x ).
let us check the given four options:-
A f(x) = √x ; f(-x) = √-x here f(x) ≠ f(-x)
B f(x) = x ; f(-x) = -x here f(x) ≠ f(-x)
C f(x) = x³ + 1 ; f(-x) = -x³ + 1 here f(x) ≠ f(-x)
D f(x) = x⁴ ; f(-x) = (-x)⁴ = x⁴ here f(x) = f(-x)
We can see that in the option D the f(x) = x⁴ is an even function because f(x) = f(-x).
Therefore the correct answer is option D. Which is the even function is f (x) = x⁴.
