Hey there! Hello!
For this problem, you first need to figure out how many questions Nicholas got right, got wrong, and didn't answer. Then, you need to compare these to how many points he gets for each one. To do the first thing I mentioned, you need to add together how many problems your question accounts for, then subtract these from 100 and assume that these are questions he got wrong.
So, he has a total of 86 problems correct (times 1 will be 86 points added to his total score), 6 problems unanswered (times 0 will be 0 points that won't affect his score), and 8 problems incorrect (times –1/4, or –0.25, will be 2 points taken away from his total score).
Then, plug them into an equation. Since the unanswered questions don't count for anything, they can be omitted.
Your final answer will be C.
Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)

Answer:
, 2 , 4
Step-by-step explanation:
x = - 3 ≠ 2 , then
g(- 3) = × (- 3)² - 4 =
× 9 - 4 =
- 4 =
x = 2 then g(2) = 2
x = 4 ≠ 2 , then
g(4) = × 4² - 4 =
× 16 - 4 = 8 - 4 = 4

Step-by-step explanation:
<u>Right Triangles</u>
A right triangle can be identified by the fact it has an internal angle of 90°. In a right triangle, the trigonometric ratios stand.
Let's consider the triangle to the left. We need to calculate side c, one of the legs of the triangle. We can use the angle adjacent to it (60°) or the angle opposite to it (30°) with the appropriate trigonometric ratio.
We'll use the adjacent angle, and
Solving for c
Rationalizing
Now for the triangle to the right. The side h is the hypotenuse. Again, any of the two angles can be used (though they are equal, for it's an isosceles triangle). For any of them it is true that
