What are the zeros of f(x) = x2 + x – 30?
A. x = –6 and x = 5
B. x = –5 and x = 6
C. x = –15 and x = 2
D. x = –2 and x = 15
Answers
Answer:
Answer A is correct. (x + 6)(x - 5) = x^2 + x - 30.
Step-by-step explanation:
Note that -30 = (-5)(6) and (5)(-6). This quadratic can be factored easily:
x^2 + x - 30 = (x + 6)(x - 5) is correct because 6x - 5x = x, the middle term of x^2 + x - 30.
Setting each factor equal to zero, one by one, we get:
x + 6 = 0 => x = -6, and x - 5 = 0 => x = 5
Answer A is correct.
Find the common ratio of the geometric sequence 36, 6, 1, 16, ... . Write your answer as an integer or fraction in simplest form.
Answers
Answer:
Step-by-step explanation:
The common ratio is the constant found by dividing any term by the previous term.
r=6/36=1/6
r=1/6
I am assuming the 16 at the end of the sequence was a typo. IF 16 was at the end of the sequence it is NOT a geometric sequence as there would not be a common ratio for all terms.

B.
60
с
25
D
300
Answers
Answer:
50 papers
Step-by-step explanation:
50% of the 200 papers would be 100 papers graded because half of 200 is 100.
25% would be 1/4 of the 200 papers.
So you have to divide.
200 divided by 4 is 50.
Therefore 50 papers have been graded so far.

Find the distance between (-2, 3) & (-7, -7). Round to the nearest tenth.
Answers
Answer:
11.2 units
Step-by-step explanation:
From (-7, -7) to (-2, 3) is 5 units horizontally and 10 units vertically. Thus we have a right triangle with sides 5 and 10 respectively. The length of the hypotenuse of this triangle is the distance between (-2, 3) & (-7, -7):
d = √(5² + 10²) = √(25 + 100) = √125 = √25√5, or 5√5.
This is approximately 11.2 units
