Answer:
1 5/7
Step-by-step explanation:
2 2/5 x 5/7
= 12/5 x 5/7
= 12/7
1 5/7
DI/dx=-850x+45500
d2l/d2x=-850 so when dl/dx=0 it is an absolute maximum for l(x)...
dl/dx=0 only when:
850x=45500
x=53.53
x=54 years of age (rounded)
Answer:
Step-by-step explanation:
Given
Position of particle is 
i.e. distance from x axis is 
Distance from y axis at
velocity is given by 
Similarly acceleration is given by
Magnitude of acceleration is 
From 1 and 2 we can see that
Magnitude of acceleration is proportional to distance from x axis
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable (a letter), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
So the terms are 9a, 4b, and 18.
hope it helps!
First let as solve all unit pirce
whistles 21.25 / 25 = $ 0.85 per unit
36 / 50 = $ 0.72 per unit
60 / 80 = $ 0.75 per unit
kazoos
10 / 25 = $ 0.4 per unit
18.50 / 50 = $ 0.37 per unit
27.20 / 80 = $ 0.34 per unit
a.) $ 0.85 - $ 0.72 = $ 0.13
b.) 10 / 25 = $ 0.4 per unit
c.) he must order 80 kazoos she should order
