Answer:
215 ft
Step-by-step explanation:
The length of the surrounding fence is equal to the perimeter of the garden. That is the sum of the lengths of the straight sides and the curved arc. The arc length is given by the formula ...
s = r·θ . . . . . where θ is the central angle in radians
__
<h3>arc length</h3>
There are π radians in 180°, so the arc will have a measure in radians of ...
θ = 132° × (π/180°) = 11/15π ≈ 2.3038 . . . . radians
Then the length of the curved side of the garden is ...
s = (50 ft)(2.3038 radian) ≈ 115.2 ft
__
<h3>perimeter</h3>
The fence length is the sum of the arc length and the two radii:
perimeter = 115.2 ft + 2×50 ft = 215.2 ft
About 215 feet of fencing are needed to enclose the garden.
Answer:
Answer: so the answer is 80 miles per 0.8 Step-by-step explanation: consistence
In order to find the y-intercept you have to plug in 0 for x in the equation, so:
f(0) = -1.4(0) - 15
When you solve, you would get y-intercept = -15
In order to find the x-intercept you have to set the equation equal to 0, so:
0 = -1.4x - 15
Solve for x and you would get -10.714...
f(15) = -1.4(15) - 15
f(15) = -36
-1.4x - 15 = 12.44
Add 15 to both sides
-1.4x = 27.44
Divide both sides by -1.4
x = -19.6
Answer:
Slope = ∆y/∆x
slope = ( -5_1 ) / ( 3_-3 )
slope = -6 / 6
slope = -1
Answer: Rational "yes"
Step-by-step explanation: The square root of 25 is indeed a rational number. Rational numbers are numbers. The square root of 25 is a perfect square which means that it has a number that can be multiplied by itself which gives us 25.
In this case, the number is 5 so yes, it's rational.
