Answer:
a) -2t²+12t+15 b) 25, 31 c) 26
Step-by-step explanation:
a) To find out rate, we will take derivative of the given equation
dN/dt= -2t2+12t+15
b) At 9 am , it will be 1hr since the start of morning shift so t=1
dN/dt= -2(1)²+12(1)+15
dN/dt=25
At 10 am, it will 2 hrs since the start of morining shift be so t=2
dN/dt=-2(2)²+12(2)+15
DN/dt= 31
c) N(2)-N(1)= (-(2)³+6(2)²+15(2))-(-(1)³+6(1)²+15(1))
=(46)-(20))
= 26
What you do is multiply .65 by 80 which gives you 52 students. Then you make 15% into a decimal( .15) and also multiply it by 80 which gives you 12 students.Finally you subract 12 from 52 which is 40. The answer is 40 students.
Answer:
we conclude that the product of w and 4 is at least - 17 is represented as:
Step-by-step explanation:
Let 'w' be the number
The product of 'w' and '4' can be written as = 4w
- Given that the product of w and 4 is at least - 17.
When we say 'at least', it means we are talking about the fact that something 'must be equal to or greater than' the other thing.
Symbolically, the phrase 'at least' is represented as the inequality symbol '≥'.
Thus, the expression becomes
4w ≥ -17
Therefore, we conclude that the product of w and 4 is at least - 17 is represented as:
Answer:
24hours
Step-by-step explanation:
let Evan be x, Tyler=x-12,equate;1/x+1/(x-12)=1/8,to get x=24 or 4.The correct value of x=24 because if you take x=4 means that Tyler=-8hours which is impossible
I remember doing this but I don’t remember my answers.
