Concave up is U-shaped.
There will be a inflection/critical point f'(x) =0 then a negative slope f'(x) = neg then another inflection/critical point f'(x) =0 at the bottom of the U-shape then a positive slope to last inflection/critical point. The interval for the Concave Up shape is the first and last inflection points.
The roller coaster is 150 ft
Answer:
Step-by-step explanation:
In order to convert kilometers to miles, we can use a formula, assuming 
is miles and 
is kilometers.
.
Since we know the kilometer reading (7), we can divide this by 1.609 to get our total miles.
Hope this helped!
25x - 6 = 24 + 5x
First we collect terms
20x = 30
Now we divide by 20
x = 30/20
x = 1.5
0.1125 kg
Step-by-step explanation:
Step 1:
Let us assume that 48 inches of coil of steel weighs 10.800 kg.
We have to find the weight of 0.5 inch coil.
Step 2:
In this problem we assume that it is given in direct relationship.
Therefore, Problem becomes
48 inches weigh 10.8 kg
0.5 inches weigh X kg
(48 / 0.5) = ( 10.8 / X)
X = (10.8 × 0.5) / 48
X = 0.1125 kg
