The equation is:
y = 10 sin(π/15 t) + 30
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.

Hope this helps :)

What is the value of x? pleeaseee answer!!!

BabaBlast [244]

If you look up "angles of 7 sided polygon" it would give a result of how many degrees polygons with 7 sides such as this one above would equal to. It's important to know that when finding x angles within.

7-sided polygons = 900 degrees in total

Since all the other angles except x are given, we can add all those up and set it equal to 900. So it would look like this:

$139+121+125+126+158+120+x=900$

Simply solve for x now.

$139+121+125+126+158+120+x=900\\ \\ 789+x=900\\ \\ x=900-789=111$

So x = 111 degrees.

Hope this helps!

Anson estimated he would need 17 hours to complete his science project. He actually needed 19 1 2 hours. What was his percent er

STatiana [176]

Answer:

The percentage of error is 14.71 %.

Step-by-step explanation:

Given:

Estimated time for completion of project is, $ET=17\ h$

Actual time for completion of project is, $AT=19\frac{1}{2}=\frac{39}{2}\ h$

Difference in error = $AT - ET = \frac{39}{2}-17=\frac{39-34}{2}=\frac{5}{2}=2.5\ h$

Percentage in error = $\frac{2.5}{17}\times 100=14.71\%$

Therefore, the percentage of error is 14.71 %

Help, I know D2 is the dilation of 2? And I know the rotation is 90 degrees but I’m not to sure on how to find my answer? Help p

maw [93]

Answer:

(-18, 2)

Step-by-step explanation:

To rotate a point by 90°:

R₉₀ (x, y) = (-y, x)

R₉₀ (1, 9) = (-9, 1)

To dilate by 2:

D₂ (x, y) = (2x, 2y)

D₂ (-9, 1) = (-18, 2)
