Answer:
Yes it does
Step-by-step explanation:
The average is shifted to higher side if higher number is present in a data set.
suppose the following set of data
20, 40 , 60, 100
avergae of data= (20+40+60+100)/ 4 = 55
now suppose following set of data
20,40,60,1000
average of data= (20+40+60+1000)/4= 280
Answer:28.25
Step-by-step explanation:
Equation is: y = - 2x^2 + 113x - 497
In order to find out maximum of X, first step is to take derrivative of the function y = - 2x^2 + 113x -497.
When we do that, derrivative function is:
dy/dx = - 2 * 2 x + 113 * 1 = - 4x +113
At the maximum point derrvative function equals to zero.
So, - 4x + 113 = 0
-4x = -113
x = 28.25
So, the selling price should be 28.25
2x^2+2x-40=0
2x^2+10x-8x-40=0
2x(x+5)-8(x+5)=0
(2x-8)(x+5)=0
2(x-4)(x+5)=0
x=-5 and 4
If you graph it, the zeros are just the values of x when the curve meets the x axis...
Answer:
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Step-by-step explanation:
Given that a roller coaster ride reach a height of 80 feet.
The height above the ground of the roller coaster is modeled by the function
h(t)=10t²-40t+80
where t is measured in second.
h(t)=10t²-40t+80
Differentiating with respect to t
h'(t)= 10(2t)-40
⇒h'(t)=20t-40
To find the minimum height we set h'(t)=0
∴20t-40=0
⇒20t =40
⇒t=2
The height of the roller coaster minimum when t=2 s.
The minimum height of of the roller coaster is
h(2)= 10(2)²-40.2+80
=40-80+80
=40 feet.
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Yes.
y represents the temperature.
x represents the number of hours past 8:00am.
