We can see from the diagram that the length of the rectangle is 2 lots of the radius of one quarter circle. The width is made up of one radius, therefore the width is half of the length.
This means that the width of the rectangle is 9cm, and the radius of each quarter circle is 9cm.
To find the shaded area, we find the area of the rectangle and subtract from the areas of each circle, which are equal:
A = lw - 1/2(pi x r^2)
A = 9 x 18 - 1/2(81pi)
A = 162 - 81/2 pi
A = 34.8cm (3sf)
Answer:
The initial value of the linear relationship is 
Step-by-step explanation:
we know that
The y-intercept is the value of y when the value of x is equal to zero
The initial value is the value of the linear function when the value of x is equal to zero
therefore
The initial value is the y-coordinate of the y-intercept of the linear function
Observing the graph
The y-intercept is the point 
so
For 
The value of y is equal to
Answer:
A
Step-by-step explanation:
Because when you are doing a reflection, You sort of see if you can fold it and it will still be the same. If you put the first triangle on the second one, they have the same shape.
Hope this helps :)
We can say at month 0 she was 43 inches tall.
And at month 18 she was 52 inches tall.
We can say that x is the number of months and y is her height.
Rise/run
y2-y1/x2-x1
52-43/18-0
9/18
1/2
So the slope is 1/2 (which is what you are looking for.) and if you were to write an equation it would be y=1/2x+43
