Answer:
65%
Step-by-step explanation:
26/40 = 0.65
0.65 X 100 =65
Answer:
banana
Step-by-step explanation:
3.9 x 10 ^-5 is the answer. 0.000039 in scientific notation is 3.9 x 10^-5
The first thing to do is to get the graph. That's below. That is a very wicked looking graph. I'm not sure what happens at 0. I'm not sure it is continuous at 0. That's something to make a fuss over because x = 0 is one of the x intercepts.
y = - x^(2/5)(x(5/5) + 7).
y = - x^(2/5)(x + 7)
So one of the x intercepts is 0 and the other one is -7.
The reasons are known because the factors can be equated to 0. It does not look to me like there is exact symmetry. There is a local minimum however at what the graph says is (-2,-6.5 or so)
You could differentiate that to find the exact point, but you are not asked for that.
So the domain is from -∞ to zero and 0 to plus ∞ I think you have to exclude 0 even though it is an x intercept.
The graph decreases from -∞ < x < -2
It increases from -2 < x < 0
It decreases form 0< x < ∞
Answer:
a) -45, <u>-43.5, -42, -40.5</u>, -39. f(n) = -45 + 1.5(n-1)
b) -34, 3, 40, 77. f(n) = -34 + 37(n-1)
Step-by-step explanation:
The explicit formula for an arithmetic formula can be defined as: f(n) = f(1) + d(n-1).
Where n is the number, and d is the common difference.
