Answer:
- 7, - 28, - 112, - 448, - 1792, - 7168
Step-by-step explanation:
Using the recursive formula and a₁ = - 7 , then
a₂ = 4a₁ = 4 (- 7) = - 28
a₃ = 4a₂ = 4(- 28) = - 112
a₄ = 4a₃ = 4(- 112) = - 448
a₅ = 4a₄ = 4(- 448) = - 1792
a₆ = 4a₅ = 4(- 1792) = - 7168
Answer:
(0,-3)
Step-by-step explanation:
To find the point of intersection for the two lines, we solve the two equations simultaneously
From the right hand side, we will need to find a way to rewriting 3x²y in terms of cube roots.
We know that 27 is 3³, so if we were to rewrite it in terms of cube roots, we will need to multiply everything by itself two more twice. (ie we can rewrite it as ∛(3x²y)³)
Hence, we can say that it's:
Hence, c = 6 and d = 2
<span>Inflection points are where the function changes concavity. Since concave up corresponds to a positive second derivative and concave down corresponds to a negative second derivative, then when the function changes from concave up to concave down (or vise versa) the second derivative must equal zero at that point. So the second derivative must equal zero to be an inflection point. But don't get excited yet. You have to make sure that the concavity actually changes at that point.</span>
Answer:
25 km
Step-by-step explanation:
1 km in 4m
so
100/4 = 25
25km
