Answer:
803.84
Step-by-step explanation:
the formula for the area of a circle is A = π r2 which is pi times the radius squared.n in this case if the circumference is 8 cm then the radius would be half of the circumference which is 4. then you square 4 which is equal to 256. Then take 256 and multiply it by pi. 256 × 3.14 = 803.84. i hope this helped you.
Answer:
![x^{2} - 3x - 10](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-%203x%20-%2010)
Step-by-step explanation:
To start, lets form our polynomial factors from our zeroes.
x = -2
x + 2 = 0
x = 5
x - 5 = 0
Now lets put these into factored form by moving them into parenthesis and multiplying them with each other!
(x+2)(x-5)
We can start moving them out! I am going to use FOIL, but you could also use distributive or any other method/property.
x · x = x²
x · -5 = -5x
x · 2 = 2x
2 · 5 = 10
Now lets put our terms into our polynomial function, based on the order of the powers.
![x^{2} - 3x - 10](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-%203x%20-%2010)
We are done! Hope this helps!
Answer:
Option A. ![C(d)=25d+12](https://tex.z-dn.net/?f=C%28d%29%3D25d%2B12)
Step-by-step explanation:
Let
d -----> the number of days
C(d) -----> the total cost
we know that
The linear equation in slope intercept form is
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the rate or slope of the linear function
b is the y-coordinate of the y-intercept
In this problem we have that
![C(d)=md+b](https://tex.z-dn.net/?f=C%28d%29%3Dmd%2Bb)
The slope of the linear equation is equal to the charge of $25 per day to board dogs
so
![m=25\frac{\$}{day}](https://tex.z-dn.net/?f=m%3D25%5Cfrac%7B%5C%24%7D%7Bday%7D)
The y-intercept is the value of y when the value of x is equal to zero
In this problem the C-intercept is the total cost when the number of days (d) is equal to zero
The C-intercept is equal to the cost of the bath $12
so
![b=\$12](https://tex.z-dn.net/?f=b%3D%5C%2412)
substitute the values
![C(d)=25d+12](https://tex.z-dn.net/?f=C%28d%29%3D25d%2B12)
