Answer:

with these characteristics, place the

semi-ellipse on coordinate axes in a convenient position and draw it.

5. What is the equation of the ellipse? How wide will the canal need to be for the

Petroleum ship?

6. Now that you know which of the two alternatives provides the widest channel, consider other

factors. His department is also in charge of verifying the depth of the channel, the

amount of river traffic and other details. For example, if there was a flood in the river and

the water level will rise 10 feet, how would free space be affected? Take a decision

about which project you think would be best as far as your department is concerned and

360^o-150^o=210^o\\\\\dfrac{210^o}{360^o}=\dfrac{7}{12}

P_{LQM}=\dfrac{7}{12}\cdot2\pi\cdot14=\dfrac{7}{3}\pi\cdot7=\dfrac{49\pi}{3}\ cm

P_{QRP}=\dfrac{1}{2}\cdot14\pi=7\pi\ cm

F(x)= -5x+9 ; reflection in the y-axis a.g(x)=5x-9 b.g(x)=5x+9 c.g(x)=9x-5 d.g(x)=5x-5
Sunny_sXe [5.5K]
<h3>Answer: g(x) = 5x+9, second choice</h3>

Explanation:

When we reflect over the vertical y axis, every negative x value becomes positive and vice versa. So we effectively replace x with -x like so

f(x) = -5x+9

f(-x) = -5(-x)+9 ... replace every x with -x

f(-x) = 5x+9

g(x) = 5x+9

A point like (1,4) on f(x) will reflect over to (-1,4) on g(x). If we apply this to every point on f(x), then all of f(x) will reflect to g(x).
