Step-by-step explanation:
step 1. if r = 2, then its area = (pi)r^2 = (pi)(4) = 4pi
step 2. if r = 3 then its area = (pi)r^2 = (pi)(9) = 9pi
step 3. so A is the area of a circle half the sum of our circles with r = 2 and r = 3.
step 4. A = (4pi + 9pi)/2 = 13pi/2 =6.5(pi).

To find:
The value of the given expression closest to the whole number.
Solution:
We have,
[tex]\dfrac{12\pi}{10\pi}\times \dfrac{5\pi}{6\pi}[/tex]
Cancel out the common factors from each fraction.
[tex]=\dfrac{6}{5}\times \dfrac{5}{6}[/tex]
[tex]=\dfrac{6\times 5}{5\times 6}[/tex]
[tex]=\dfrac{30}{30}[/tex]

plot an x onto the 4 on th y line and a 2 on the x line

The solution to the equations are
a) The coordinates of point P is P ( 0 , 4 ) and Q is Q ( 2 , 0 )
b) The graph is plotted with points P and Q
c) The equation of line is 4x + 2y = 8
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
4x + 2y = 8 be equation (1)
Now , the coordinates of the point P = P ( 0 , y )
The coordinates of the point Q = Q ( x , 0 )
Substituting the values in the equation , we get
when x = 0
4 ( 0 ) + 2y = 8
2y = 8
y = 4
So , the coordinates of the point P = P ( 0 , 4 )
when y = 0
4x + 2 ( 0 ) = 8
4x = 8
x = 2
So , the coordinates of the point Q = Q ( 2 , 0 )
Now , the equation of line is 4x + 2y = 8
when x = { -2 , -1 , 0 , 1 , 2 , 3 }
The values of y are y = { 8 , 6 , 4 , 2 , 0 }
So, the line is plotted in the graph
Hence , the equation of line is 4x + 2y = 8

Answer:
3500
(0,3500)
Step-by-step explanation:
The y - intercept of the line is at (0, 3500).
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have the line models the height of a glider [y] in feet over [x] hours
The y - intercept i.e. the point where the graph cuts the [y] axis. From the graph we can see that point is (0, 3500).
Therefore, the y - intercept of the line is at (0, 3500).
