Answer:
Step-by-step explanation:
The first term is the first one on the list:
a[1] = 5
__
The ratio of terms is ...
-10/5 = -2
That is, each term is -2 times the previous one, so the recursive rule is ...
a[n] = -2·a[n-1]
Answer: It decreases on the interval (-infinity, 3)
This is the same as saying -infinity < x < 3, or simply x < 3
=============================================================
Work Shown:
f(x) = (3−x)^2 + 5
f(x) = (-x+3)^2 + 5
f(x) = (-1(x-3))^2 + 5
f(x) = (-1)^2*(x-3)^2 + 5
f(x) = 1(x-3)^2 + 5
The last equation is in the form y = a(x-h)^2 + k
We have a = 1, h = 3 and k = 5
The vertex is (h,k) = (3,5)
Since 'a' is positive, this means the function decreases on the left and increases on the right (forming a parabola that opens upward). See below.
So the function is decreasing when x < 3, which represents everything to the left of the vertex.
We can expand that out to -infinity < x < 3 which converts to the interval notation (-infinity, 3)
5 days to drive 225 miles
225 x .1= 22.50
230-22.50= 207.5
207.5/41.50= 5 days

May 06, 2018 · Real estate agents, car dealers, and pharmaceutical sales representatives earn commissions that are a percentage, or part, of sales. For example, a real estate agent might earn a portion of the selling price of a house that she helps a client purchase or sell.

Answer: 1/4
Step-by-step explanation:
In a stack of 24, the 2 mediums are odd and even cards in this question. This means that 1/2 the cards are even and 1/2 are odd. To get a even card once is a 1/2 chance, then to get it again is 1/2 x 1/2 chance or 1/4 chance. This is what I think.
