Answer:

18.8496 units (rounded o1ff to four decimal places)

Step-by-step explanation:

Arc length = 2 × π × r × \frac{central-angle}{360}

r (radius) = 12 units ÷ 2 = 6 units

Central angle = 180°

For our semicircle, the arc length = 2 × π × 6 × \frac{180}{360} = 18.8495559215 units

Or 18.8496 units (rounded o1ff to four decimal places)

Nitella [24]

x-------> the number of persons in the family

f(x)------> the function represent the cost of living

we know that

The domain of the function  would only include positive integers, because the number of persons can not be negative or a fraction

The range of the function would only include positive numbers, because the cost can not be negative

therefore

What is the equation in slope intercept form of the line that contains the point (8, -2) and has a y-intercept of -4?
Alecsey [184]
Y=mx+b,slop intercept form
we need to find the slope.we nned to point
(-8,2) is given you can get the other by understanding the defintion of y-intercept (0,-4)
m = slope =  \frac{ 2  - ( -  4)}{ - 8 - 0}  =  \frac{6}{ - 8}
m=-6/8,b=y-intercept=-4
y =  \frac{ - 6}{8} x  + ( - 4)

12u–9u–5u+13= -5<br><br> find u
NikAS [45]
To solve this, we combine like terms. Our equation becomes:

-2u + 13 = -5

Now to subtract both sides by 13 to find that:

-2u = -18

Finally, we divide both sides by the coefficient and find that:

u = 9
