Determine the percentage change
Percentage change is calculated as;






<em>Hence, the percentage change is approximately 8.8%</em>
Write a recursive rule for the sequence.
-2,0,2,4,6
STEP 1:
a1 = -2
a2 = 0
a3 = 2
STEP 2:
d = a2-(a1)=a3
= d = 0-(-2)=2
STEP 3:
An = a+(n-1)d
ANS:
Do you mean the nearest 10th
Answer:
B, D
Step-by-step explanation:
-3(0.15 - 0.2 +0.25p) = -3(-0.05 +0.25p) = 0.15-0.75p
A doesn't work because -3(0.15 - 0.2 +0.25p) = -0.45+0.6-0.75
C doesn't work because 3(0.15+0.2+0.25p) = 0.45+0.6+0.75 which doesn't equal -0.45+0.6-0.75.
E doesn't work because 0.15-0.2 = -0.05 not 0.05.
K is centroid of the the triangle => The answer is 7.5
