A wind turbine has three equally spaced blades that are each 131 feet long. What is the measure of the arc between any two blades?
Answer:
274.23 feet
Step-by-step explanation:
From the question,
The measure of the arc between any two blades (s) = 2πrΦ/360
s = 2πrΦ/360................... Equation 1
Where Ф = angle formed betwen two blades, r = length of each blade.
Given: Ф = 360/3 (the three blades are equally spaced) = 120°, r = 131 feet.
Constant: π = 3.14
Substitute these values into equation 1
s = (2×3.14×131×120)/360
s = 274.23 feet.
Hence, the measure of the arc between any two blades is given = 274.23 feet

Write an equation in standard form for a line that is perpendicular to the line with an equation of y = 3x —5 that passes through the point (8, 5).
Answer:
x + 3y = 23
Step-by-step explanation:
m = -1/3, find 'b'
5 = -1/3(8) + b
15/3 = -8/3 + b
23/3 = b
y = -1/3x + 23/3
multiply each side by 3 to get:
3y = -x + 23
x + 3y = 23

The angles surrounding the point p are 90 degrees
Then using the angle given, find the missing angles.
JPH = 90
HJP = 49
90+49 = 139
180 - 139 = 41
Therefore JHP = 41
HLP = HJP = 49
HLP = 49
KLP = 72
KLP + HLP = 72 + 49 = 121
Therefore, HLK = 121
LP = JP = 16
JP = 16
HL = HJ = 13
HL = 13

Maya throws a rock
straight up from the edge
of a 192-foot cliff and into
the ocean. After two
seconds, the rock
reaches a maximum
height of 256 feet. Four
seconds later, the rock
enters the ocean
Write an equation to
model the scenario.
Answer:
Step-by-step explanation:
2.256 = 4x
So first Maya throws the rock from the 192-foot cliff into the ocean.
After 2 seconds, the rock reaches a maximum height of 256 feet;
so 2 seconds, 256 feet - 2.256After 4 seconds, the rock reaches the ocean.
so 4 seconds, it reaches the ocean but we don't know how many feet. ( x )-- 4 seconds, x feet.equation: 2 . 256 = 4 . xGood luck!
The required equation that represents the scenario is x = 64 * 2 + 256 * 4
Given that,
Maya throws a rock straight up from the edge of a 192-foot cliff and into the ocean. After two seconds, the rock reaches a maximum height of 256 feet. Four seconds later, the rock enters the ocean. To write an equation to model the scenario.
the equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
let the total distance covered by the rock vertically be x,
now,
Distance traveled by the rock vertical upward in 2 seconds = 2 * (256 - 192)
= 2 * 64
Distance traveled by the rock vertical downward in 4 seconds = 4 * 256
Total distance,
x = 2 * 64 + 4 * 256
Thus, the required equation that represents the scenario is x = 64 * 2 + 256 * 40.

The circumference of a circular pool is 43.96 meters. What is the area in square meters? Use 3.14 for pi.
A. 153.86
B.145.30
C.138.03
D.47.10
Answer:
The answer is letter A
Step-by-step explanation:
Area of a circle in terms of radius:
A circle of radius = 6.996 or 7, or diameter = 13.99 or circumference = 43.96 meters
Area = π · r^2 = 3.14 * 7^2 = 153.86 square meters
