Answer:
D 73º
Step-by-step explanation:
Total angles
a = (sides - 2) * 180
a = (5 - 2) * 180
a = 540
-------------------
Missing angle
x = 540 - (104 + 118 + 96 + 115)
x = 107
a is supplementary to x
m∠A = 180 - 107
m∠A = 73º
Your answer is About 1815 deer
When values of a quadratic function are listed in a table with x-values having a constant difference, the y-vlaues will have a constant (non-zero) second-difference.
Here, we can list first and second differences for the values in the given tables to identify the quadratic function.
Table 1.
- 1st differences: 3, 3, 3, 3
- 2nd differences: 0, 0, 0, 0 . . . . this is a linear function
Table 2.
- 1st differences: -6, -2, 2, 6
- 2nd differences: 4, 4, 4 . . . . this is a quadratic function
Table 3.
- 1st differences: 5, -8, -3, -3
- 2nd differences: -13, 5, 0 . . . . can be described by a 4th degree polynomial
Table 4.
- 1st differences: 3, 0, -3, -3
- 2nd differences: -3, -3, 0 . . . . can be described by a 4th degree polynomial
___
The appropriate choice is Table 2.
Answer:
C
Just a circle is used to construct a hexagon
Hi!
First, let me explain that open circles mean that the answer starts after or before that number. So if the answer is c < 4, the answer would be D, and not B.
If the answer was c ≤ 4, the answer would be B, and not D.
I hope that makes sense. Now let's solve the inequality.
Remember that whatever we do to the inequality, we have to do it to both sides.
We need to isolate c on one side.
10c + 5 ≤ 45
Start by subtracting 5 from both sides.
10c + 5 - 5 ≤ 45 - 5
10c ≤ 40
Divide by 10 on both sides.
10c/10 ≤ 40/10
c ≤ 4
The answer is B.
Hope this helps! :)
