Find the exact length of the curve. Use a graph to determine the parameter interval.

1 answer:

4 0

The formula for the length of a polar curve is∫r2+(dr/dθ)2 from a to b.

In this case, dr/dθ is the derivative of the function r which is equal to -cos (theta/2) * sin (theta/2) which is equal to -1/2 cos theta. Since there are no limits defined, we leave the formula as it is but one can use the calculator if there are limits present already

Answer:

4 1/10 kg

Step-by-step explanation:

To find the total mass, we add the mass of the three baskets

1 1/10 + 1 3/10 + 1 7/10

Since they have the same denominator

1 1/10

1 3/10

1 7/10

Write x2 - 8x - 3 in vertex form.

crimeas [40]

Vertex form:

y = a(x - h)² + k

I have not learned this stuff yet, but by using online calculators, I can determine that the vertex form is:

Y = (x - 4)² - 19

I believe so :/
