Answer:
[tex]\text{1. } v=16t+\frac{h-c}{t},\\\text{2. }90\:\mathrm{ft/s}, \\\text{3. Cannot be determined}[/tex]
Step-by-step explanation:
1. The initial equation given to us is [tex]h=-16t^2+vt+c[/tex]. Rearranging the equation to isolate [tex]v[/tex], we have:
[tex]vt=16t^2+h-c,\\\boxed{v=16t+\frac{h-c}{t}}[/tex]
2. Using the equation we rearranged in part 1, we can substitute given values:
[tex]v=16(3)+\frac{131-5}{3},\\v=48+42=\boxed{90\:\mathrm{ft/s}}[/tex]
3. We see from our equation in part 1 ([tex]v=16t+\frac{h-c}{t}[/tex]) that when [tex]t=0[/tex], the denominator of our fraction will be equal to 0. Since we cannot divide by 0, the velocity remains undefined and cannot be determined.

Given:
The values are [tex]a=0.\overline{6},b=0.75[/tex].
To find:
The values of [tex]ab[/tex] and [tex]\dfrac{a}{b}[/tex].
Solution:
We have,
[tex]a=0.\overline{6}[/tex]
[tex]a=0.666...[/tex] ...(i)
Multiply both sides by 10.
[tex]10a=6.666...[/tex] ...(ii)
Subtracting (i) from (ii), we get
[tex]10a-a=6.666...-0.666...[/tex]
[tex]9a=6[/tex]
[tex]a=\dfrac{6}{9}[/tex]
[tex]a=\dfrac{2}{3}[/tex]
And,
[tex]b=0.75[/tex]
[tex]b=\dfrac{75}{100}[/tex]
[tex]b=\dfrac{3}{4}[/tex]
Now, the product of a and b is:
[tex]ab=\dfrac{2}{3}\times \dfrac{3}{4}[/tex]
[tex]ab=\dfrac{1}{2}[/tex]
The quotient of a and b is:
[tex]\dfrac{a}{b}=\dfrac{\dfrac{2}{3}}{\dfrac{3}{4}}[/tex]
[tex]\dfrac{a}{b}=\dfrac{2}{3}\times \dfrac{4}{3}[/tex]
[tex]\dfrac{a}{b}=\dfrac{8}{9}[/tex]
Therefore, the required values are [tex]ab=\dfrac{1}{2}[/tex] and [tex]\dfrac{a}{b}=\dfrac{8}{9}[/tex].
Answer:
ab = 1/2 and a/b = 8/9

What is the area of a circle with a circumference of 30 feet?
Answers
Exact Area = 225/pi
Approximate Area = 71.65605
The approximate value is using pi = 3.14; I rounded to the five decimal places. The units for the area are in square feet, which can be written as "sq ft" or "ft^2" without quotes.
============================================================
Explanation:
C = 30 is the circumference
C = 2*pi*r ... is the circumference in general
Equate the two right hand sides and isolate r
2pi*r = 30
r = 30/(2pi)
r = 15/pi
This is the exact radius in terms of pi
Plug this into the area formula to get...
A = pi*r^2
A = pi*( r )^2
A = pi*( 15/pi )^2
A = pi*( 225/(pi^2) )
A = 225/pi
This is the exact area in terms of pi. If your teacher wants the exact answer, and only this, then you can stop here.
If your teacher wants you to use pi = 3.14 as the approximation, then we'll get an approximate area of roughly A = 225/pi = 225/3.14 = 71.65605 square feet. Use more decimal digits in pi to get a better approximation.
What is the Inverse equation to Y= 1/2x - 3?
Answers
Answer:
Y = 1/(2X+6)
Step-by-step explanation:
First, you swap X and Y, getting
