Answer: If you are looking for Slope-Intercept form (y=mx+b), It would be...
y=-5.4x+10840.4.
If you are looking for Point-Slope form, it would be...
y=-5.4x+10840.4.
Step-by-step explanation: Write in Slope-Intercept from, y=mx+b.
Point-Slope form : Use the Point-Slope formula, y-y1=m(x-x1) to find the equation of the line.
I hope this helps you out! ☺
Answer:
<u>18 waves</u> hit the beach in 49 s.
Step-by-step explanation:
Given:
The frequency of the waves that were coming into the beach is 0.367347 Hz.
Now, to find the number of waves that hit the beach in 49 s.
Let the number of waves be
The frequency of waves () = 0.367347 Hz.
The time it takes to hit the beach () = 49 s.
Now, we put formula to get the number of waves:
<u><em>The number of waves = 18.</em></u>
Therefore, 18 waves hit the beach in 49 s.
SA=4pir^2
78.54km^2=SA
78.54=4pir^2
divide both sides by 4
19.635=pir^2
aprox pi=3.14 so divide both sides by 3.14
6.25318=r^2
sqrt both sides
2.50063=r
round
radius=2.5km
this question is flawed in that it gives the wrong units
answer is the option with 2.5 in it
