we know that
triangles BCD and ACE are similar
so, their ratios of sides must be equal
Calculation of y:
we can see that
AC=AB+BC
AC=y+3
CE=CD+DE
CE=4+6
CE=10
now, we can plug values
now, we can solve for y
Calculation of AC:
we know that
AC=y+3
we can plug y
and we get

Answer:
49.12 ft^2
Step-by-step explanation:
We can add the areas of the two figures
We have a triangle
A = 1/2 bh
A = 1/2 (6)(8)
A = 24
We have 1/2 of a circle so find 1/2 of the area
A = 1/2 ( area of a circle)
= 1/2 ( pi r^2)
The diameter is 8 so the radius is 4
= 1/2 ( 3.14 * 4^2)
= 25.12
Add the areas together
24+25.12 = 49.12
9514 1404 393
Answer:
C. jump discontinuity at x=-2
Step-by-step explanation:
At x=-2, you have to lift your pencil to keep drawing the graph. That means there's a jump discontinuity there.
This function has a jump discontinuity at x = -2.
__
<em>Additional comments</em>
At x=3, there is no discontinuity in the function. The <em>derivative</em> of the function has a discontinuity there, as there is an abrupt change in slope at that point.
If left and right limits exist and are the same at a point, but the graph is not defined at that point, then a <em>removable</em> discontinuity exists. All that is needed to fill the hole is to define the function at that point.
