Answer:
c = 7p
Step-by-step explanation:
If 1 person buys the platter, the bill is c = 1 × $7.
If 2 people buy the platter, the bill is c = 2 × $7.
If 3 people buy the platter, the bill is c = 3 × $7.
(Do you see the pattern yet?)
If "p" people buy the platter, the bill is c = p × $7.
We ususally say "c is in dollars" and drop the "$" sign from the equation. When p is multiplied by 7, we conventionally write it as 7p.
... c = 7p
Circular pen means you are going to use Area = Pi(r^2).
So 78.5 = pi(r^2). Divide by pi on both sides to get r^2 = 78.5/pi. Take the square root of that to get r or radius = approximately 4.99. If you need an exact answer then use
for the next part because you are not done yet.
Plug whatever R you use into the circumference formula of Circumference = 2(pi)(r).
If you use 4.99, you do 2(pi)(4.99) which is approximately 31.35. If you use the exact answer, you do 2(pi)(
) which gives you approximately 31.41.
Either way you'll need about 31 meters of chicken wire but the 31.40796 or ~31.41 is closer to the exact answer.
Te sample space is s= {1,2,3,4,5,6}
It’s kind of hard to read which number the ends are on. Can you take a better picture?
Answer:
f'(x) = 4
Step-by-step explanation:
- Derivative of 3 (constant number) is 0
- Derivative of 4x is 4
- f'(x) = 4 - 0 = 4
