Multiply the top and bottom by 10
2 becomes 20 so....
8 becomes 80
Answer:
21 in²
Step-by-step explanation:
Following the formula, you set it up as ![\frac{3(6+8)}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%286%2B8%29%7D%7B2%7D)
Add 6 and 8
![\frac{3(14)}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%2814%29%7D%7B2%7D)
Multiply 3 and 14
![\frac{42}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B42%7D%7B2%7D)
Divide 42 by 2
21 in² = area of trapezoid patio
Answer:
There is a decrease of 0.75 sales per day
Step-by-step explanation:
Given:-
- The price of item = p
- The number of sales = x
- The relationship between "p" and "x" is given below:
4p+4x+2px=56
Find the rate at which x is changing when x=2, p=6, and dp/dt=1.5 The rate at which x is changing is [ ] sales per day
Take the time derivative (d/dt) of the entire given expression and apply chain rule on d/dt ( 2px ). Since both "p" and "x" are only functions of time "t":
d/dt
4p+4x+2px=56
4*dp/dt + 4*dx/dt + 2*(x*dp/dt + p*dx/dt)=0
Use the given values x=2, p=6, and dp/dt=1.5 to determine dx/dt
4*1.5 + 4*dx/dt + 2*(2*1.5+6*dx/dt)=0
6+4dx/dt + 2*(3+6dx/dt)=0
6+4dx/dt + 6+12dx/dt=0
12+16dx/dt=0
12=-16dx/dt
dx/dt= 12/-16
= -0.75
