The travel of the barnacle would be the circumference of the circle.

Circumference formula is 2 x PI x r

Circumference  = 2 x PI x 1m

= 2 x PI

If you use 3.14 for PI the circumference is 2 x 3.14 = 6.28 m.

Round the answer as needed.

Answer:

I had a hard time finding the answers, so here are the answers for the whole assignment

the barnacle travels 2PI M  

the boat is traveling at 2PI seconds  

distances- a=1/2, b=1, c=3/2, d=1, e=0, f=-1

the graph shows the zero-max-sero-min-zero pattern

this is the pattern for a sine function

amplitude= 1

vertical shift=0

an equation for this graph is y=sin x

When the boat has traveled 7 meters, the height of the barnacle is approximately: 0.657 m

10 meters= -0.544

Explain how to determine the following from the graph:

Number of times the barnacle went beneath the water level if the boat traveled a distance of 20 m

sample response= Number of meters of the 20 m trip that the barnacle was underwater  

When the graph is below the x-axis, the barnacle is underwater.The graph dips below the x-axis three times between x = 0 and x = 20, so the barnacle goes underwater three times.Every time the barnacle goes underwater, the boat travels  meters (one half the circumference of the wheel) before the barnacle comes back up, so the barnacle covers 3  meters underwater between x = 0 and x = 20.

Find the following (take ground level to be 0):

Gum’s minimum height: 6 ft

Gum’s maximum height: 8 ft

2nd part= 2PI  

complete the table a=6, b= 7, c= 8, d=7, e=6

Explain how to use the graph to write an equation to model the gum’s height....  

The pattern is min-zero-max-zero-min, which is the pattern for a cosine function of the form y = acos(x) + k, but is reflected over the x-axis (so a < 0).

The amplitude is |a|, so a = –1 and |a| = 1.

The midline is exactly between the max and the min, y = (6 + 8)/2 = 7, so k = 7.

The equation is y = –cos(x) + 7.

Graph the function y = –cos(x) + 7...  

sample response= The gum returns to the wall each time the graph shows a minimum value of 6 (the height of the wall).Count the number of minimums that occur between x = 0 ft and x = 60 (but omit the first time when x = 0).The gum returns to the wall 9 times while traveling a distance of 60 feet.

good luck :)

Answer:

∠ECF = 37°

Step-by-step explanation:

∠ACG = 37°   because it is a complementary angle to 53° (37° + 53° = 90°)

∠ECF = 37° because it is a vertical angle to 37°

HELP ASAP!!! 40 POINTS
ICE Princess25 [194]

Using derivatives, it is found that the x-values in which the slope belong to the interval (-1,1) are in the following interval:

(-15,-10).

<h3>What is the slope of the tangent line to a function f(x) at point x = x0?</h3>

It is given by the derivative at x = x0, that is:

m = f^{\prime}(x_0).

In this problem, the function is:

f(x) = 0.2x^2 + 5x - 12

Hence the derivative is:

f^{\prime}(x) = 0.4x + 5

For a slope of -1, we have that:

0.4x + 5 = -1

0.4x = -6

x = -15.

For a slope of 1, we have that:

0.4x + 5 = 1.

0.4x = -4

x = -10

Hence the interval is:

(-15,-10).

Help please will mark u brainliest !!!!!

Step-by-step explanation: To make a line paralle to another, the slope has to be the same such as the "m" in "y=mx+b" the y-intercept or "b" could be different. In this case, the slope is -7. So the question mark should be -7.
