1 answer:

Answer:

the answer is B

Step-by-step explanation:

area of the minor arc is teter all over 360 times 2 pie r square.

that is

\frac{?}{360}  \times 2\pi {r}^{2}

= but because the question said for length AB, youvhave to use only one radius.

\frac{160}{360}  \times 2 \times  \pi \times 9

You the use 40 to cancel 160 and 360 to get 4 all over 9 times 2 pie times 9.

\frac{4}{9}  \times 2 \times \pi \times 9

You then cancel 9 with 9 to get 4 times 2 times pie

4 \times 2 \times \pi

this is equal to

8\pi

Answer:

Solving the given formula for v2 gives us:

a(t_2-t_1)+v_1 = v_2

Step-by-step explanation:

Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.

Given equation is:

a = \frac{v_2-v_1}{t_2-t_1}

Multiplying both sides by t2-t1

(t_2-t_1) . a = \frac{v_2-v_1}{t_2-t_1} . (t_2-t_1)\\a(t_2-t_1) = v_2-v_1

Adding v1 to both sides of the equation

a(t_2-t_1)+v_1 = v_2-v_1+v_1\\a(t_2-t_1)+v_1 = v_2

Hence,

Solving the given formula for v2 gives us:

a(t_2-t_1)+v_1 = v_2
