Answer:
I don't think any of those answers represent pi
first of all the circumference of the circle is pi* diameter since the circumference of the circle is 43.96 feet and the diameter is 14 feet the equation would look like this 43.96=14*pi,pi=43.96/14,so that means the pi would obviously be 3.14
I´m pretty sure I´m correct.
Answer:
Distance he covers in
of an hour =
miles.
Step-by-step explanation:
Phillip rode his bicycle at
miles per hour.
To find distance he covers in
of an hour.
Solution:
Speed at which Phillip rides =
miles per hour
Time for which he cycles =
of an hour
Distance covered in miles 
To multiply mixed numbers we need to convert them to fractions.
![[A\frac{b}{c}=\frac{Ac+b}{c}]](https://tex.z-dn.net/?f=%5BA%5Cfrac%7Bb%7D%7Bc%7D%3D%5Cfrac%7BAc%2Bb%7D%7Bc%7D%5D)

⇒ 
⇒ 
Then we simply multiply the numerators and denominators.
⇒
Then we convert back to mixed fraction by dividing numerator by denominator and writing the quotient as whole number with fraction (remainder as numerator and denominator being the divisor)
⇒
miles.
∴ Distance he covers in
of an hour =
miles.
Answer:
A)Predicted value = 103.5
B)Actual value = 102
C)So, these are not same
Step-by-step explanation:
The researcher used the line
to model the data.
A)When the researcher substituted the value of x = 65 into this equation, what is the resulting y value?
Substitute value x=65 in equation :
y = -0.1 x +110
y=-0.1(65)+110
y=103.5
Predicted value = 103.5
B)Based on the coordinates of the given data points, what is the actual actual vision score when x=65?
Use the given graph
When x = 65
y = 102
So, The actual actual vision score when x=65 is 102
C)When the researcher substituted x = 65 into the line of equation, is the resulting y value the predicted value or the exit value for the vision score of a 65-year-old? Use your results for parts a and b to answer this question.
Predicted value = 103.5
Actual value = 102
So, these are not same
Answer: yes, it is
Step-by-step explanation:
A number is divisible by 6 if it is divisible by 2 and 3 simultaniously.
n = k(k+1)(k-1)
If k-1 is a multiple of 3, n is divisible by 3, so one of the requirements is ok.
Now, if k-1 is a multiple of 3, it can be even or odd.
if k-1 is even, then it is divisible by 2 and as it is divisible by 3 as well, n is divisible by 6
if k-1 is odd, then k and k+1 is even, hence, divisible by 2.
As n = k(k+1)(k-1), n is also divisible by 6.
Answer: The cause of exponential decay. Sowwy if im wrong
Step-by-step explanation:
An inverse variation function is not the best model because the data points show an exponential decay. The fact that this is true for ALL of the points shown indicates we have an inverse variation of the form x*y = k where k = 60 in this case. ... For any inverse variation, as x increases, y will decrease (and vice versa).
