Given the width of the lawnmower is 5 feet and the
length of the rope is 20 feet, calculate the radius (R) of
the pole that will produce a perfect lawn.
R=
Answer:
R=0.39789 ft
Step-by-step explanation:
For the perfectly mowed lawn, after one revolution, you want the lawnmower to be exactly one lawnmower's width closer to the pole. This implies that one lawnmower width should wrap around the circumference of the pole every revolution. So for this lawnmower we want:
2πR=2.5
⇒R=2.5/2π
R=0.39789 ft

The following linear equation represents the line of best fit for the following scatter plot
y=0.15x-1.5
Use the equation to answer the following questions. Predict the amount of home runs a player would have if they hit 200 times.
A) 25 home runs
B) 1,366 home runs
C) 28.5 home runs
D) 30 home runs
Answer:
C) 28.5 home runs

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityStep-by-step explanation:
Step 1: Define
y = home runs
x = hits
[Best Line of Fit] y = 0.15x - 1.5
We can use this to predict the average of the scatter plot.
hits = x = 200 times
Step 2: Solve for y home runs
Substitute [BLF]: y = 0.15(200) - 1.5Multiply: y = 30 - 1.5Subtract: y = 28.5Remember that this is only a prediction. Actual data can vary. The best line of fit tells us that if a player hits 200 times, we would get approximately 28.5 home runs.
Answer:
[tex]\huge\boxed{\text{(C) 28.5 home runs}}[/tex]
Step-by-step explanation:
If we are given the equation to this graph, we need to substitute a value in to get the output of the function.
Since the question is asking us how many home runs a player will earn if they hit 200 times, and we know that the x value is the number of hits, we can substitute 200 into the equation as x and find the value of y.
[tex]y =0.15x-1.5[/tex] [tex]y=0.15\cdot 200-1.5[/tex] [tex]y=30-1.5[/tex] [tex]y=28.5[/tex]Therefore, 28.5 home runs would be scored with 200 hits.
