Alex wants to find out how many ducks there are in a park.

1 answer:

8 0

An estimate for the number of ducks would be 62.

There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.

worty [1.4K]

If the integral is

$\displaystyle \int (ax^2+2bx+c)^{3/2}(2ax+2b)\,\mathrm dx$

substitute $u = ax^2+2bx+c$ and $\mathrm du=(2ax+2b)\,\mathrm dx$ . Then you end up with

$\displaystyle \int u^{3/2}\,\mathrm du = \frac25u^{5/2} + C$

which in terms of <em>x</em> is

$\boxed{\dfrac25(ax^2+2bx+c)^{5/2} + C}$

How many gallons of a 70% antifreeze solution must be mixed with 60 gallons of 20% antifreeze to get a mixture that is 60% a

Flura [38]

We have 60 gallons of 20% antifreeze.

How much 70% antifreeze do we add to get 60% antifreeze?

We'll make "x" the gallons of 70% we must add.

.20 * 60 + .70 x = .60 * (60 + x)

12 + .70x = 36 + .60x

.10x = 24

x = 240 gallons of 70% antifreeze.
