Joe tracked the height of his Dalmatian puppy from age 13 weeks to 25 weeks. He graphed the data and determined the line of best
nadya68 [22]

Answer:

22.5 weeks

Step-by-step explanation:

y = 1.12x + 28.78 represents the height of the puppy.  Here that height is 54 cm:

Then 54 = y = 1.12x + 28.78

Combining the constants, we get 1.12x = 25.22.  Dividing both sides by 1.12, x turns out to be 22.5 weeks.

Answer if you know
Arlecino [84]
I've attached a plot of one such cross-section (orange) over the region in the x-y plane (blue), including the bounding curves (red). (I've set y=1.25 for this example.)

The length of each cross section (the side lying in the base) has length determined by the horizontal distance x between the y-axis x=0 and the curve y=\sqrt x. In terms of y, this distance is x=y^2. The height of each cross section is twice the value of y, so the area of each rectangular cross section should be 2y^3.

This means the volume would be given by the integral

\displaystyle\int_0^22y^3\,\mathrm dy

Find the distance between (4,2) and (-4,-4)
VikaD [51]
Use the distance formula, and plug in values.
d = \sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1} )^{2}}
<u />d = \sqrt{( -4-4 )^{2}+( -4-2 )^{2}}
d = \sqrt{( -8 )^{2}+( -6 )^{2}}
d = \sqrt{64+36}
d= \sqrt{100}

Therefore, the distance is equal to "10".
