A golf course has a circular island of grass with a diameter of 15 yards. The mowing company charges $6.50 per square yard. How much will the golf course have to pay to maintain the grass on the circular island?
Answers
Answer:
about $1148.06
Step-by-step explanation:
Your goal is to find the area of the island of grass and multiply that area by the cost per square yard.
Area = radius * radius * pi
You are told that the diameter = 15 yards. We also know that the radius that we need is half of the diameter. Radius = 7.5 yards.
This means that the Area = 7.5 * 7.5 * 3.14 = 176.625 square yards
Then we multiply by the cost per square yard:
176.625 * 6.50 = 1148.06 is your answer
Will cost about $1148.62

A) A'(4,3)
B) A'(3, 4)
C) A'(-4,-3)
D) A (1,4)
.
Answers
Answer:
The answer will be A) A'(4,3)
Step-by-step explanation:
90 degrees will send the rectangle to Quadrant 1, the rectangle itself has also been rotated so by rotating the rectangle 90 degrees and putting it in place for quadrant 1, it should give you the answer.

A can of tuna is in the shape of a cylinder. The distance around the top of the cylinder is approximately 251.2 mm. The tuna company plans on making the cap opener the length of the radius of the top. What will the length of the cap opener be?
Answers
Answer: 40 mm
===============================================================
Explanation:
I'm assuming your teacher used pi = 3.14 to compute the circumference.
If so, then,
C = 2*pi*r
251.2 = 2*3.14*r
251.2 = 6.28r
6.28r = 251.2
r = (251.2)/(6.28)
r = 40 mm is the radius

Answer:
164.48 or 164.5
Step-by-step explanation:
So, to make it simpler, you can do the circle like this: 3.14×(8×8). Then you can work down!
3.14 × 64
200.96
and then because it's halved, you divide by 2
100.48
then that's the half circle
The square would just be 8×8=64
then add the circle and the square and viola!

Hi there! Before we start with your problem. Recall the Trigonometric Function of (-x) first.
sin(-x) = -sinx cos(-x) = cosxtan(-x) = -tanxNow what we need to do is to imagine a unit circle. We know that angle (-x) rotate clockwise while (x) rotates counterclockwise.
Now imagine if it rotates clockwise, it:d start at the fourth quadrant first. That means the y-value is negative while x-value is positive.
We also know that (x, y) = (cos, sin)
Now move to the 2(pi)/3.
[tex] \large{ \frac{2 \pi}{ 3} = \frac{2(180)}{3} \longrightarrow 2(60)= \boxed{120 \degree}}[/tex]
Thus, the value of 2pi/3 is 120°
Now imagine again. In a unit circle, 120° is in second quadrant if we rotate counterclockwise. But if we rotate clockwise, where would the 120° be? Remember that (-x) rotates clockwise. That's right! (-120°) is in the third quadrant. In the third quadrant, cos is negative there along with sin.
So we can conclude that:
cos(-120°) is in third quadrant. cos and sin are negative in third quadrant.120° is also a reference angle of 60° because of 180°-60° = 120°
Thus,
[tex] \large{cos( - \frac{2 \pi}{3} )= cos( - 120 \degree) = cos(120 \degree) \longrightarrow - \frac{1}{2} }[/tex]
Answer/Conclusions
cos(-2pi/3) = -1/2cos(-2pi/3) use the reference of 60°cos(-2pi/3) is in third quadrant.5/6 divided by 2/3=
