Answer:
<h3>The answer is 471 feet</h3>
Step-by-step explanation:
Since the the track is circular
Circumference of a circle = πd
where
d is the diameter
π = 3.14
From the question
diameter = 150 feet
Circumference = 150π
= 150(3.14)
We have the final answer as
<h3>Circumference = 471 feet</h3>
Hope this helps you
Make an inference about which fish increased its predicted average population from Year 1 to Year 2.
All three types of fish increased their predicted average population.
Trout increased its predicted average population.
Bass increased its predicted average population.
None of the fish increased their predicted average population.
It's like: (6.5x42)/100
the answer is 2.73
The radius of the circle is the square root of (123/pi) = 6.257 feet to 3 decimal places.
Answer:
I can't see Mathieu's work but I will show the right steps and maybe you can find where Mathieu went wrong.
f(x)=x^2+4x+3
f(x)=(x+3)(x+1) Since 3*1=3 and 3+1=4
The x-intercepts can be found by setting y to 0 and solving for x
(in other words replace that f(x) thing with 0 and solve for x)
0=(x+3)(x+1)
Now set both factors equal to 0
x+3=0 or x+1=0
x =-3 x=-1
The x-intercepts are at (-3,0) and (-1,0)
