Step-by-step explanation:
If x = 30 and y = 36
(Instead of 6 add 8 to 40 to be proportional
Answer:
(2) The motorcycle cost $12,000 when purchased.
Step-by-step explanation:
In the standard exponential equation, y = ab^x, a is the original value.
Since the equation is V(t) = 12,000(0.75)^t, a is 12,000.
This means that the original value was 12,000.
So, the motorcycle cost $12,000 when it was first purchased.
The correct answer is (2) The motorcycle cost $12,000 when purchased.
The description expresses three points which can be used for a standard form equation. The vertex is stated to be (0,0) and is a maximum; two other points are (-21,-74) and (21,-74)
The equation for vertex form of a parabola:
y=a(x-h)^2+k
vertex (h,k)
thus our equation will be:
y=a(x-0)^2+0
thus
y=ax^2
using one of the points, the value of a will be:
-74=a(21)^2
a=-74/441
thus the equation will be:
y=-74/441x²
Answer:
778
Step-by-step explanation:
We have the length of stay as X
X~N (9,(2.4))
The sample is given as n = 1000
P(7<x<14) is what we are trying to get
P(7-9/2.4 < x-9/2.4 < 14-9/2.4)
= P(-0.83<z<2.08)
P(z<2.08)-p(z<-0.83)
When we go to the z table,
0.981-0.0203
= 0.778
0.778x1000
= 778
So in conclusion, 778 of these guests can be expected to stay between 7 and 14 days.
