Using the first derivative test, it is found that the graph is increasing on the interval is (-5, ∞).
<h3>What is Function?</h3>
A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B.
Here, the function is given by:
f(x) = x²/2 + 5x + 6
On differentiating both sides, with respect to x we get
f'(x) = x + 5
Then, we test the signal of the derivative, which is the first derivative test.
x + 5 ≥ 0
x ≥ -5
Thus, It is found that the Function is increasing on the interval is (-5, ∞).

I got you. The answer would be A (Certificate)
Answer If you are saying to multiply then the answer is 60y
Answer: If the second train arrives at the station 18 minutes after the first one DEPARTS, then there's a train waiting at the station for 2 minutes out of every 20.
So the probability a train will be there when you arrive is
2/20 = 0.1
Responder:
- 30 ° C
Explicação passo a passo:
Dado que :
A temperatura diminui 1 ° para cada 200 m afastados da superfície terrestre
Temperatura na superfície da terra = 20 ° C
Temperatura atmosférica a uma altura de 10 km de. Superfície Terrestre :
Queda de temperatura para uma altura de 10 km de distância;
10km = 10 * 1000 = 10.000 m
1 * (10000/200)
1 * 50
= 50 ° C
Portanto ;
Temperatura da superfície terrestre - 50 ° C
20 ° C - 50 ° C
= - 30 ° C
