Answer: $112, 16 trips
Step-by-step explanation:
You would plug 9 into the equation for t. Then for the total amount until she was out of money you would divide 256 (her total amount of money) by 16 (the toll cost per trip)
Answer:
\int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx
Step-by-step explanation:
Arc length is calculated by dividing the arcs in to small segments ds
By pythagoren theorem

then integrate ds to get arc length.
We are given a function as
y = sin 2x in the interval [0, pi/2]
To find arc length in the interval
Arc length 
Hence arc length would be
B)
Answer:
y = 0, -4
Step-by-step explanation:
1) Factor out the common term 3y.

2) Solve for y.
<em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>0</u></em><em><u>,</u></em><em><u> </u></em><em><u>-4</u></em>
<em><u>Therefor</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>0</u></em><em><u>,</u></em><em><u> </u></em><em><u>-4</u></em><em><u>.</u></em>
Answer: 30
Step-by-step explanation:
Example
x=y
x+z=y+z
If we subtract the same number from both sides of an equation, both sides will remain equal.
Example
x=y
x−z=y−z
If we divide both sides of an equation by the same number, both sides will remain equal.
Example
x=y
x÷z=y÷z
If we multiply both sides of an equation by the same number, both sides will remain equal.
x=y
x⋅z=y⋅z
