Exact product of 379*8 is 3,032.
The windmill's blade measures 7 feet in length.
<h3>
What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
To find the measure of the windmill's blade:
- We have the equation:

- At the time 't' = 0, the end of the blade is parallel to the ground and pointing to the right, indicating that it is the same height as the other end. (Ф = 0°)
- We may calculate the length of the blade by calculating the greatest height of this end at = 90°.
- We now know that the general model equation of a circular simple harmonic motion is written as follows: y = A sinωt + k
- Where A is the maximum displacement from mean to maximum position
- The angular frequency is ω.
- When eq1 and eq2 are compared:
- A = 7
- As a result, the difference in blade end height at = 0° and = 90° is 7 feet.
Therefore, the windmill's blade measures 7 feet in length.

The correct question is given below:
The equation h=7sin(pi/21t)+28 can be used to model the height, h, in feet of the end of one blade of a windmill turning on an axis above the ground as a function of time, t, in seconds. How long is the blade? Assume that the blade is pointing to the right, parallel to the ground, at t = 0, and that the windmill turns counterclockwise at a constant rate. 7 feet 14 feet 21 feet 28 feet
The maximum mileage per gallon for the compact car is determined by taking the first derivative of the given equation and equate to zero. The differentiated form is m's = -0.05 s + 2.45 = 0; s is equal to 49 seconds. substituting this s, m is equal to 30.025 miles/gallon.
Yes, I think so because if it’s basically 8:30 and she is 3/4 miles away from her house, she is almost at school
Equivalent expressions are expressions with equal values
The equivalent expression is 16.5d+9
<h3>How to determine the equivalent expression</h3>
The expression is given as:
14.5d+8.5-1/2d+1/2+2.5d
Express the fractions as decimals
14.5d+8.5-0.5d+0.5+2.5d
Collect like terms
14.5d-0.5d+2.5d+8.5+0.5
Evaluate the like terms
16.5d+9
Hence, the equivalent expression is 16.5d+9
