Answer
I attach the image of the circle in the picture below
Circumference larger circle = 62.831 in
Step-by-step explanation:
The perimeter of a circle is defined as
P = 2* pi* r
where
r corresponds to the radius of the circle.
In this case,
r = d/2 = 3 in
The perimeter of the smaller circle results
P1 = 2*(3.1416)*(3 in) = 18.8495 in
The circumference of the smaller circle is 30% of the circumference of the larger circle, so
P1 = 0.3* P2
P2 = 18.8495 in / 0.3 = 20 = 62.831 in
A is true. There is no vertical line that can intersect this graph twice.
B is false. The function is defined for all
.
C is true. The minimum value of
is 
.
D is false. The piecewise function is made of one semicircle and one line, just two functions.
E is also false. The circular arc is a nonlinear function.
Thus, the answer is A and C.

Answer:
(a)4 units, 3 units
(b) Right-angled triangle
Step-by-step explanation:
We are given that
Let location of drinking fountain, A =(-4,2)
Location of the bench, B=(0,2)
Location of the center of the slide ,C=(0,5)
a. Distance formula
Using the formula
units
Hence, the distance from the drinking fountain to the bench=4 units
The distance from the bench to the center of the slide=3 units
(b)
units
The triangle ABC satisfied the Pythagoras theorem. Hence, the triangle ABC is a right angled triangle.
