32-12 20
Your answer would be (b.) because -2+-3=-5
Answer:
A recursive formula is a formula that defines each term of a sequence using preceding term(s). Recursive formulas must always state the initial term, or terms, of the sequence.
Step-by-step explanation:
Was that the definition you were asking or the question?
The time it will take before Diego catches up with Linh will be after 8 hours
Let :
<u>Diego</u> :
- Travel speed = 75 mph
- Travel time = t
<u>Linh</u>:
- Travel speed = 60 mph
- Travel time = t + 2
Recall :
- Distance covered = speed × time
- Distance covered by Linh = 60(t + 2)
- Distance covered by Diego = 75t
<u>Time</u><u> when Diego catches up with Linh</u> :
Diego's distance = Linh's distance
75t = 60(t + 2)
Solve for t ;
75t = 60t + 120
Collect like terms
75t - 60t = 120
15t = 120
Divide both sides by 15 to isolate t
t = (120 / 15)
t = 8
Hence, Diego will catch up with Linh after 8 hours.

Answer:
30 cm
Step-by-step explanation:
1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal
h, l and w are known; discover V, S and d
V = lwh
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal
S, l and w are known; discover h, V and d
h = (S - 2lw)/(2l + 2w)
V = lwh
d = √(l2 + w2 + h2)
3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal
V, l and w are known; discover h, S and d
h = V/lw
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal
d, l and w are known; discover h, V and S
h = √(d2 - l2 - w2)
V = lwh
S = 2(lw + lh + wh)
