you place 30 in the place of X, and it becomes 4×30-10. in PEMDAS, multiplication goes first and 4×30=120. 120-10=110
Answer:
Jonas = 60 pounds
Jane = 70 pounds
Remember- 5 or more, raise the score. 4 or less, let it rest.
Jonas is 63 pounds. 3 is less than 4, so rounded to the nearest ten would be 60 pounds.
Meanwhile, Jane is 67 pounds. 7 is more than 5, so we will raise the score.
So, 67 rounded to the nearest ten would be 70.
You have your answers. 60 and 70. Hope this helps!
Answer:
poop
Step-by-step explanation:
poop
If A=38x-x^2 then
dA/dx=38-2x
d2A/dx2=-2
Since the acceleration, d2A/dx2 is a constant negative, when velocity, dA/dx=0, it will be an absolute maximum for A(x)
dA/dx=0 only when 38=2x, x=19
A(19)=38(19)-19^2
A(19)=722-361
A(19)=361 ft^2
So the maximum possible area is 361 ft^2
(This will always be true as the maximum possible area enclosed by a given amount of material will always be a perfect square...)
