Answer:
a(4) = -18
Step-by-step explanation:
The fourth term in the sequence is when n = 4. Substitute n = 4 into the rule a(n)=-6-4(n-1).
a(4) = -6 - 4(4-1)
a(4) = -6 - 4(3)
a(4) = -6 - 12
a(4) = -18
Step-by-step explanation:
) y2 = 4x
differenting both side with respect to x
dy²/dx=d4x/dx
2y dy/dx=4
dy/dx=4/2y=2/y
Answer:
21
Step-by-step explanation:
ratio of baskets to tries = 5:7
if 45 baskets are made, how many tries?
5 : 7
45 : x
we cross multiply
5x = 45*7
x = 63 potential points from trials
since each try is worth 3 points, 63/3 = 21
They had 21 3-point tries
First convert the 15 minutes to seconds
60 sec-= 1 minute
900 sec = 15 minutes
ratio and proportion
85 blinks/900 sec= 51 blinks/ x seconds
cross multiply
85x=45900
divide by 85
x= 540 seconds
hope this helps
