Picture attached, please help.
Andrej [43]

Answer:

-1

Step-by-step explanation:

∫x^2 -x +1 dx = x^3/3 -x^2/2 +x  evaluated at 1  subtracting the value at 0

1/3 -1/2 +1  - (0/3 -0/2 +0)

5/6

Now lets find

∫x^2 -x +1 dx=x^3/3 -x^2/2 +x  evaluated at 2  subtracting the value at 1

2^3/ 3 -2^2/2 +2 - (1/3 -1/2 +1 )

8/3 -2 +2 - (5/6)

8/3 -5/6

11/6

The total is 5/6 - 11/6 = -6/6  or -1

Y∝√x If y=60 when x=36 find,y when x=16
avanturin [10]

Answer:

y = 10√16) = 40

Step-by-step explanation:

This says, "y is proportional to the square root of x."  We are told that y = 60 when x = 36.  Find the formula for this function.  Then, determine what value y will take on when x = 16.

y = k√x  becomes 60 = k√36, or 60 = 6k.  Then k must be 10, and the formula is y = 10√x.

If x = 16, y = 10√16) = 40
