A circular swimming pool has a radius of 28 ft. There is a path all the way around the pool that is 4 ft wide. A fence is going
1 answer:
Answer:
201
Step-by-step explanation:
assuming we are finding the circumference of the outer circle or the path to find the length of the fence we start by combining the radius of the pool and the path width for the radius of the second circle around the first one. the circumference or C is equal to 2 x the radius or r you can also use the diameter or d, times
for the circumference
with this info we can figure out the answer
lets say = 3.14
32 = r
r x 2 = d
d x = 200.96 rounded its 201
the circumference is 201

Answer:
1a. 8
1b. AB & BC
1c. AC
2. miles
3. NO
Step-by-step explanation:
1a. AC is your hypotenuse which is C² and BC is B², so we plug it in the equation.
A²+6²=10²
A²+36=100
A²=64
A=
A=8
1b. Legs are the two shorter sides, AB & BC, which are 6 & 8 respectively.
1c. The hypotenuse is the longest side AC
2. Make lines that make the graph for a triangle with a line. My graph is linked below. Then counts the points, AC=6, BC=4, then use the pythagorean therom.
6²+4²=X²
36+16=52
=X
3. 15²+17²=19²
514=361
not possible
so it is not a right triangle
Part A.
In this part we have to find the increasing interval .
Increasing interval is that interval where graph goes up. And from the graph we can say that the graph goes up in the interval
And that's the increasing interval .
Part B.
Correct option is B
x and y intercepts
x intercept is the point where graph touches the x axis. And the graph touches the x axis at x=-1 and 1 .
So the x intercepts are
y intercepts are the point, where the graph touches or crosses the y axis.
Therefore the y intercept is (0,1)
So the correct option is D .
