33. First you would make 3(2)^2= 36 - 2(2) = 32 +1 is 33

Tanx-cotx / sinxcosx =sec^2-csc^2x. Please show all steps.

Katarina [22]

$\bf \cfrac{tan(x)-cot(x)}{sin(x)cos(x)}\implies \cfrac{\frac{sin(x)}{cos(x)}-\frac{cos(x)}{sin(x)}}{sin(x)cos(x)}\implies \cfrac{\frac{sin^2(x)-cos^2(x)}{cos(x)sin(x)}}{\frac{sin(x)cos(x)}{1}}
\\\\\\
\cfrac{sin^2(x)-cos^2(x)}{cos(x)sin(x)}\cdot \cfrac{1}{sin(x)cos(x)}\implies \cfrac{sin^2(x)-cos^2(x)}{cos^2(x)sin^2(x)}
\\\\\\
\textit{and now, we distribute the denominator}
\\\\\\
\cfrac{sin^2(x)}{cos^2(x)sin^2(x)}-\cfrac{cos^2(x)}{cos^2(x)sin^2(x)}\implies 
\cfrac{1}{cos^2(x)}-\cfrac{1}{sin^2(x)}$

and surely you know what that is

long story i am in a long distance relationship and her dad needs her to get all her math done. nether of us understand it. i mi

stepan [7]

Answer:

1. y-(is that a 7 or a 1?) = 2(x-4)

2. y-4 = (1/2)(x-2)

3. y = (2/3)(x+6)

... and so on

The formula for a line given point and slope is :

y - (y-value of point) = slope * x - (x-value of point)

How can I find the derivative problem using the quotient rule?

Lady_Fox [76]

You must do the quotient thing and then add 45.76 and subtract 32.

Your answer is 23.76x

First answer gets brainliest. You do not need to do the graphing or the shading, just pls tell me the inequalities

Aleksandr-060686 [28]

Answer:

y $\geq 20-x$

$y\geq 40-5x$

Step-by-step explanation:

8 nickels = 40 cents

y < 8

x < 35

Let's test

1 nickel and 35 pennies. That doesn't work

4 nickel and 20 pennies. That works. Perhaps we be more precise?

5 nickels and 15 pennies. Right on the point. 20 coins.

Hope this helps :)

Have a nice day!
