Answer:
7069.5 ft^2
Step-by-step explanation:
Step one:
given data
dimension
radius of 15 feet
height of 60 feet
Required
The surface area of the tank
Step two:
![A=2 \pi rh+2 \pi r^2](https://tex.z-dn.net/?f=A%3D2%20%5Cpi%20rh%2B2%20%5Cpi%20r%5E2)
substitute
![A= 2*3.142*15*60+2*3.142*15^2\\\\A=5655.6+1413.9\\\\A=7069.5](https://tex.z-dn.net/?f=A%3D%202%2A3.142%2A15%2A60%2B2%2A3.142%2A15%5E2%5C%5C%5C%5CA%3D5655.6%2B1413.9%5C%5C%5C%5CA%3D7069.5)
A= 7069.5 ft^2
X + y = 5 is graph C
y = x - 5 is graph E
y = -5 - x is graph A
y = -5 is graph D
x = -5 is graph B
Answer:
Step-by-step explanation:
Recall that when we are factoring a polynomial, we are implicitly finding its roots. By finding a root, we are looking for a value of x (say c) such that p(c) =0. When this happens, our polynomial has the the polynomial (x-c) as a factor.
We are given the values of p at some values of x. We notice that p(5) = 0 and p(-12) =0. So, this means that our polynomial has as a factor the polynomials (x-5) and (x+12).
Answer:
82 websites per year.
Step-by-step explanation:
take the difference in the number of websites from both years, divide it by the year difference (9) to find how many per year were created
The formula for a circle is:
(x-p)^2+(y-q)^2=r^2
The radius is given (r=6), as well as the centre of the circle (-2;3).
"p" and "q" represent the coordinates of the centre of the circle.
So it would look like this -
(x-p)^2+(y-q)^2=r^2
p=x-coordinate (-2)
q=y-coordinate (3)
r=6
(x-(-2))^2+(y-(3))^2 =6^2
(x+2)^2 + (y-3)^2 = 36
***"^" means "to the power of"
