Answer: y=-13/12x-7
Step-by-step explanation:
To find the slope-intercept form, we first need to find the slope. To find the slope, you use the formula 
. We use the two given points to find the slope.
Now that we have our slope, we can start filling out the slope-intercept form equation.
y=mx+b
y=-13/12x+b
Since we don't know the y-intercept, we can use one of the given points and solve for b.
6=(-13/12)(-12)+b [multiply (-13/12) and -12]
6=13+b [subtract both sides by 13]
b=-7
With the y-intercept, we can complete our equation.
y=-13/12x-7
We use direct proportionality:
360⁰......Pi×R² (full circle)
120⁰.......x
x=120×pi×R²/360=pi×R²/3
x=pi×4²/3=16.76mi²
A=3×pi cm², for an angle of 2×pi/3=120⁰
In a similar way we compute the area of the full circle:
360.........x
120..........3×pi
x=3×pi×360/120=9×pi=3²×pi.
Thus the radius is 3cm.
Answer:
you can solve problems by this equation
Answer:
The answer is 20 songs.
Step-by-step explanation:
i) there are 19 pop songs
ii) there are 29 R&B songs
iii) the number of songs that have to be listened to in order to guarantee you hear one pop song and one R&B song
= 19 + 1 = 20 songs.
Answer:
337.08
Step-by-step explanation:
The formula is : y = 300 x [(100+6)/100]^2 = 337.08
