Answer:
4 questions
Step-by-step explanation:
To find a percentage of a number, you move the decimal mark all the way to the left.
87.5% becomes 0.875
Next you multiply 32 by 0.875 to find the percentage of questions that are completed
32 x 0.875 = 28
28 out of 32 questions have been solved, so now you subtract 28 from 32
32 - 28= 4
There are 4 questions to complete
Answer:
Vertex is (-5, -1)
(-3, 3) is a point on the parabola.
Step-by-step explanation:
f(x) = x² + 10x + 24
Let (h, k) be the vertex
h = -b/2a = -10/2(1) = -5
k = f(-5) = (-5)^2 + 10(-5) + 24
= 25 - 50 + 24 = -1
Vertex is (-5, -1)
Now, let x be some value different than -5, say -3
f(-3) = (-3)^2 + 10(-3) + 24
= 9 - 30 + 24 = 3
So, (-3, 3) is a point on the parabola.
