Step-by-step explanation:
Read the answer above/ below mine, I just wanted to point out that to solve this problem you use the circumference formula! The circumference of a circle is 2pi(r). r= radius= 10 (because 10 mi). Plug this into a calculator by typing: (20*pi) [division symbol] 8 =, and then it will give you 7.85..., but remember to round up to 7.9.
{(-2, 1), (3, 11), (-4,-3), (-2, 8), (0,5)}
Yes
No
Answer:
no because the x value -2 has two corasponding y values
Step-by-step explanation:
The greatest common factor of 14, 56, and 63 is,
⇒ 7
We have to give that,
Numbers are,
14, 56 and 63
Since, The highest number that divides exactly into two more numbers, is called Greatest common factor.
Now, Factors of the numbers are,
14 = 2 x 7
56 = 2 x 2 x 4 x 7
63 = 3 x 3 x 7
Hence, the greatest common factor of 14, 56, and 63 is,
⇒ 7

B) 4 hours
C) 5 hours
D) 7 hours
The maximum number of hours that Michael can rent a bike is 7 hours. Then the correct option is D.
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
A bike rental company charges $50 for the first hour and $25 for each additional hour. Michael must spend no more than $200 on his bike rental for the day.
Let x be the number of hours. Then the linear equation will be
25x + 50 = 200
Simplify the equation, then we have
25x = 175
x = 7
The maximum number of hours that Michael can rent a bike is 7 hours. Then the correct option is D.

Complete question :
Physics students drop a ball from the top of a 100 foot high building and model its height as a function time with the equation h(t) = 100 - 16t^2.The height, h, is measured in feet and time, t, is measured is seconds.
Find the value of h(0). Include proper units. What does this output represent?
Answer:
Kindly check explanation
Step-by-step explanation:
The model given :
Height, h as a function of time :
h(t) = 100 - 16t^2
To find h(0): substitute 0 for t in the model defined ;
h(0) = 100 - 16(0)²
h(0) = 100 - 0
h(0) = 100
The output gives the height at which the ball was before it was dropped, it depicts the height when the travel time of the ball is 0
