Answer:
Step-by-step explanation:
given is a function as

We are to find the area form x=1 to x=t
The curve from x=1 lies in the I quadratnt.
So area above x axis is to be calculated
Area = 
a) When t =10,
area = 
b) t=100
area = 
c) t=10000
area = 
Answer:
5 <= y <= 85
Step-by-step explanation:
Since the lowest weight possible is 5lbs (just the barbell and no weights) the lowest point of the range is 5lbs (the y intercept when x = 0)
The highest weight possible is 85lbs since, there is only 8 pairs of weight plates (8 is the input value) and the pairs each weigh 10lbs (the slope of the graph) + 5lbs from the barbell (y-intercept).
Using the function given, if you input 8 as the x value, you get
85 = 10(8) + 5
So the highest value of the range is 85lbs, therefore the range is 5 <= y <= 85.
Answer:
126
Step-by-step explanation:
180-54=126
Answer:
x = 3
Step-by-step explanation:
First you want to divide both sides by 5 to get 2x-4 = 2.
Afterwards, you add 4 to both sides of the equation. 2x = 6
Divide both sides by 2. x = 3
