The correct answer is
The explicit formula is of the form
,
where a₁ is the first term and r is the common ratio. Comparing this to our explicit form, we see that r = -4 and a₁ = 7.
The recursive formula is of the form
; using r=-4 gives us
The computation shows that the change in points is 89 3/4 points.
<h3>How to compute the value?</h3>
From the information, at the beginning of the day the stock market goes down 30 3/4 points and stays at this level for most of the day and at the end the stock market goes up 120 1/2 points.
Therefore, the change will be:
= 120 1/2 - 30 3/4
= 89 3/4

#SPJ4
Answer:
1. 1/3, 4
2. 3/5, -2
3. 4, 1
4. -3/2, 3
5. 1, 4
Step-by-step explanation:
- The slope is x and to find it do (rise over run) for example 5/3, but since it is done for you that is not needed. That was just a reference.
- The y-intercept is where the number hits the y-axis when at 0.
Answer:
$0.5
Step-by-step explanation:
Given :
Hours ___Lot A Cost ($) ___ Lot B Cost ($) 4____________19.00 _____ 20.00
8 ___________ 33.00 ______ 32.00
Using the equation :
y = mx + C
m = slope = Hourly charge
C = intercept = set park fee
m = y2 - y1 / x2 - x1
For LotA:
m1 = (33 - 19) / (8 - 4)
m1 = 14 / 4
m1 = 3.5
For LotB:
m2 = (32 - 20) / (8 - 4)
m2 = 12 / 4
m2 = 3
Since, m is the hourly cost :
Difference = m1 - m2
= 3.5 - 3
= $0. 5
