Pick two points
(0,0) and (2,3)
(3-0)/(2-0) = 3/2 slope
Solution: y = 3/2x
-4 + 8 = 4;
4 - 16 = -12;
-12 + 32 = 20;
20 - 64 = -44;
-44 + 128 = 84;
84 - 256 = -172.
The sum of the first 7 terms in this series is -172.
I hope this helps!
You write the problem as a mathematical expression
3x^2 + 30x + 75 =
Factor: 3 out of 3x^2 + 30x + 75.
3 (x2 + 10x + 25)
Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2
Answer:
1) 8%
2) 18 groups
3) b. 23 groups
Step-by-step explanation:
2/25 × 100 = 8%
One each group: 2/25
2/25 × 224 = 17.92
Atleast 2 freshmen: 5
5/25 × 115 = 23
