I'm taking the liberty of editing your function <span>v = e5xey: It should be
</span>
<span>v = e^5x^ey, with " ^ " indicating exponentiation.
</span>
Did you mean e^(5x) or (e^5)x? I'll assume it's e^(5x).
The partial of v = e^(5x)e^y with respect to x is e^(5x)(5)*e^y, or 25x*e^y.
The partial of v = e^(5x)e^y with respect to y is e^(5x)e^y.
Answer: The correct answer is 341 children
Step-by-step explanation:
Firstly you solve for the number of children that like both types of ice cream.
Let us assume it to be x
(150 - x )+ x + (125 - x) + 166 = 391
150 + 125 + 166 - x + x - x = 391
441 - x = 391
X = 441 - 391
X = 50
Since 50 children like at least one type of ice cream, subtracting it from the total no. of children will give the number of children that like at most one type
Therefore, 391 - 50 = 341 children
Alternatively,
Sum up children who like only chocolate ice cream + pistachio ice cream only + does who don't like any type of ice cream
= (150 - 50) + (125 - 50) + 166
= 100 + 75 + 166
= 341 children
You can calculate the velocity of each individual worker and model the velocity of both working together as the sum of the two individual velocity. Then you solve for the time.
Jack's velocity: 28 boxes / 2 h = 14 boxes / h
Walter's velocity: 36boxes / 3h = 12 boxes / h
Together velocity, V = 14 + 12 = 26 boxes / h
65 boxes => V = 65 boxes/t => t = 65 boxes / V
=65 boxes / 26boxes/h = 2.5 h
The equation that models the situation is V = 65/ t or t = 65/V
Answer:
its a 30% increase
Step-by-step explanation:
If 250 is 100% then you need an increase by 75 to get to 325
250*.3 = 75
75 is 30% of 250
250 + 30% (75) = 325
3035/100 but I'm sure you can simplify it from there. If not message me
