Answer:
see the attachment for a graph
Step-by-step explanation:
You know the cos(θ) function has a maximum of 1 at θ=0 and 2π, and a minimum of -1 at θ=π. You know it has zeros at θ=π/2 and 3π/2. Here, θ=2x, so all of these θ-values will be cut in half to turn them into values for x.
Here, too, the function is multiplied by -3, so the maximum cos(2π)=1 becomes the minimum on your graph, -3cos(2x)=-3 where x=0 or π.
<u>Answer-</u>
<em>Strip with </em><em>2.13 ft </em><em>width can be used. </em>
<u>Solution-</u>
A club swimming pool is 21 ft wide and 41 ft long.
Hence, the perimeter of the swimming pool is
The club members want a uniform width border around the pool.
They have enough material for 264 ft²
As they will cover the perimeter of the rectangular pool, so the length of the total used strip is equal to the perimeter of the swimming pool.
Let the width of the strip is x ft
So, the total area of the used strip is,
Putting the values,
Therefore, strip with 2.13 ft width can be used.
Answer:
7.2 hrs
Step-by-step explanation:
26.1 / 7.25 * 2 =
Step-by-step explanation:
Double t
t+t=2t
Subtract v
2t-v
Subtract u
2t-v-u
For this case we have the following equation:
We must find the value of "x":
We apply cube root on both sides of the equation to eliminate the exponent:
We can write 375 as
So:
Then, the correct options are:
