NICKI MINAJ IS THE QUUEN OF RAP.
Answer:
After two days, 240 degrees was water.
Step-by-step explanation:
24 hours = 1 day
72 hr/24 hr = 3 days
Therefore, one full rotation takes 3 days.
1 rotation = 360 degrees
360 degrees/ 3 days = 120 degrees per day
120 degrees x 2 days = 240 degrees
240 degrees was watered after two days
Answer:
a) 
b) 
Step-by-step explanation:
From the question we are told that:
Rate r=90 units per hour
Setup cost =20
Operating Cost =26
Units=40000
Generally the equation for Total cost is mathematically given by
Differentiating
Equating equ 1 to zero
Therefore
Substituting n
For Equ 1
F(n)>0
For Equ 2
F(n)'<0
Answer:
10 hours and 30 minutes
Step-by-step explanation:
2 weeks*7 days = 14 days
He runs 45/day *14 days = 630 minutes
But we want hours and minutes
we know 60 minutes is 1 hours
60*10 = 600 so 10 hours is 600 minutes
630-600 =30
he runs 10 hours and 30 minutes
We are given equation of parabola: y= x^2.
We know, the vertex form of the parabola is given by function
y= a(x-h)^2 +k.
Where coefficent a is the called the vertical scale factor of parabola.
We need to find the equation of parabola that is scaled by a factor 7 vertically of the given parent fuction of the parabola.
Therefore, for the given problem we have the value vertical scale factor a =7.
So, we need to put 7 in front of x^2 in the given function.
Therefore, y = 7 x^2 is scaled vertically by a factor of 7 of the y= x^2 parabola.
