2/5 = m / 70
cross multiply because this is a proportion
(5)(m) = (2)(70)
5m = 140
m = 140/5
m = 28 <===
Answer:
domain {- 5, 5 }
Step-by-step explanation:
given values in the range, that is values of y then to find the domain equate f(x) to the given values in the range, that is
x + 5 = 0 ⇒ x = - 5
x + 5 = 10 ⇒ x = 10 - 5 = 5
domain is x ∈ { - 5, 5 }
Answer:
± 5.59
Step-by-step explanation:
We already know the distance and the acceleration, but we're looking for the time.
D = 1/2at²
50 = 1/2 · 3.2t²
50 · 2 = 1/2 · 2 · 3.2t²
100 = 3.2t²
t = ± 5.59
5.59 · 3.2² = 100
Answer:
In the Amazon rainforest, the agouti (a small rodent) and the brazil nut tree are very dependent on each other. The brazil nut tree drops its pods when they ripen, but they would not split open if it were not for the agouti's sharp teeth - the only forest animal which can split the tough pods. The agouti benefits by eating the brazil nuts, but like squirrels, agoutis hide and bury surplus nuts - and many of these take root, thus replenishing stocks of brazil nut trees.
