Answer:
75
Step-by-step explanation:
1/3 * 5² * 9 = V
1/3 * 25 * 9
= 75
Answer:....
Step-by-step explanation:
first we need to find the base of the triangle, so the total is 20, they also give us 12, so we subtract 20-12=8 now divide. 8/2=4. Now we use the 4 and the 60. We use SOH-CAH-TOA, they give us the base now we need to find AB which is the hypotenuse. So we take out the TOA, and the 4 is the adjacent so we take out the SOH, we have CAH now, so we use cos. Now equation time....
since x is the bottom we switch
, which equals 8. AB=8.
Now to find the perimeter. We still use the 4 to find the hypotenuse so we can find the outside side. For this one they tell us to use 45, so now lets see what method we use. SOH-CAH-TOA. We need the hypotenuse and they give us the adjacent, so we use cos again. Now setting up the equation...
x is at the bottom again to we switch.
which equals to 5.657 or you can round it. Now we add everything.
20+12+5.657+5.657= 45.314 or you can round it to 45.
The answer is: "

or, write as: "
0.63333333333..." ; or, round to: "
0.6333" .

Answer:

Step-by-step explanation:
The given equation is 
Differentiate both sides with respect to x

Take y and 1 to other sides of the equation

Factor out dy/dx from the left hand side of the equation

Divide both sides by (x+1)

You need to find the slope
