"The perimeter P..." gives us one variable to work with.
"is" in this context almost always means "equals".
"the sum" we know we will be adding.
"twice the length l" gives us a variable and a coefficient.
"twice the width w" gives us a variable and a coefficient.
The equation for this is P=2l+2w
I hope in the future you can remember these tips! :)
Answer What is your question man?
Step-by-step explanation:
First, you must know these formula d(e^f(x) = f'(x)e^x dx, e^a+b=e^a.e^b, and d(sinx) = cosxdx, secx = 1/ cosx
(secx)dy/dx=e^(y+sinx), implies <span>dy/dx=cosx .e^(y+sinx), and then
</span>dy=cosx .e^(y+sinx).dx, integdy=integ(cosx .e^(y+sinx).dx, equivalent of
integdy=integ(cosx .e^y.e^sinx)dx, integdy=e^y.integ.(cosx e^sinx)dx, but we know that d(e^sinx) =cosx e^sinx dx,
so integ.d(e^sinx) =integ.cosx e^sinx dx,
and e^sinx + C=integ.cosx e^sinxdx
finally, integdy=e^y.integ.(cosx e^sinx)dx=e^2. (e^sinx) +C
the answer is
y = e^2. (e^sinx) +C, you can check this answer to calculate dy/dx
Answer:
First, we use distributive property:
Now, remember that 
, then
Then,
Answer: 12 cups of salad blend are in the resulting mixture
Explanation:
Since we have given that
4 cups of a salad blend contains 40% spinach
Using mixture allegation method, we get that
8 cups of a salad blend contains 55% spinach as shown in the figure below.
Now, we need to find the number of cups of salad in the resulting mixture,
Hence, 12 cups of salad blend are in the resulting mixture .
