Circumference of a circle =2πr
Diameter=2×radius
r=250km
Circumference=2×3.14×250
1570km
Answer:
y-5=5(x-1)
Step-by-step explanation:
Point slope form is: y-y1=m(x-x1)
y1 here is 5 and x1 is 1, because those are the points in the ordered pair given.
y-5=x-1 would be your base answer, but you need to account for the slope as well, which is m. So, y-5=5(x-1)
Hope this helped! :)
Answer:
p(4p - 9) =12 ⇒ 4p² - 9p = 12 ⇒ 4p² - 9p - 12 = 0
- This is a quadratic equation
p(4p - 9) - 12 ⇒ 4p² - 9p - 12
- This is a quadratic expression
