Draw a graph of Lin's distance of a function of time for this situation:

Mathematics
1 answer:
Pavlova-9 [17]2 years ago
3 0

Step-by-step explanation:

Given

Lin walks half a mile at a constant rate i.e. Lin velocity is constant. So, in the graph, it will be a straight line through the origin.

Lin is still for five minutes and after she began sprinting for the slip up to halfway i.e. Lin is accelerating or velocity is increasing for the halfway and later she started walking for the rest of the way.

The answer is A I am pretty sure. This is because in choice B, you would be dividing 7 and the sum of x + 5. In choice C you would not be multiplying 7 and the sum of x + 5. When he question asks for the product, it is asking for you to multiply. In choice D you would not just be squaring y, you would be squaring 2xy, which is not what we want. We only want to square y, therefore I believe the correct answer is A.

Find the volumes of the solids whose bases are bounded by the circle x^2 + y^2 = 9, with the indicated cross sections taken perp
labwork [276]

<em>x</em> ^2 + <em>y</em> ^2 = 9   =>   <em>y</em> = <em>y(x)</em> = ± √(9 - <em>x</em> ^2)

Each cross section would be a square with side length equal to the vertical distance between the upper and lower semicircles defined by <em>y(x)</em>, which is

√(9 - <em>x</em> ^2) - (- √(9 - <em>x</em> ^2)) = 2 √(9 - <em>x</em> ^2)

The area of each square section is the square of this length,

(2 √(9 - <em>x</em> ^2)) = 4 (9 - <em>x</em> ^2) = 36 - 4<em>x</em> ^2

We get the whole solid for -3 ≤ <em>x</em> ≤ 3, so integrating gives a volume of

\displaystyle\int_{-3}^3(36-4x^2)\,\mathrm dx=\boxed{144}
