Answer: b > 13
Step-by-step explanation: b= 14 and 14 is larger than 13. So using the greater than symbol is correct.
The temperature 6 hours after day break is 53 degrees
Step-by-step explanation:
The temperature was 65 degrees at daybreak. Then it dropped two degrees per hour until dusk. This decrease in temperature can be modeled by the equation,
y = -2x + 65
according to this equation
y= temperature after day break
x= no of hours ( in this case 6)
So equation becomes
y= -2 (6) +65
y= 65- 12
y= 53 degrees
So the temperature 6 hours after day break is 53 degrees

If you break down the beginning part, its 150 ÷ 3 = 50, so that means each class took 50 minutes. Not only that, you get your 'Time/Minutes per Class'. From there, you can multiply 50 by 5 and get 250 minutes, or 4 hours and 10 minutes.
In short: 250 minutes or 4 hours and 10 minutes.
Answer:
Area of square= side*side
So we will have,
14*14
= 196cm²
"Circumscribed rectangles" means that any Riemann Sum (left or right) must overestimate the area under the curve. So, a Right-Riemann sum would underestimate the area under the curve, and that's where you made your mistake. You will use the Left-Riemann Sum to approximate the area under the curve r(t) = tan(cos(xt) + 0.5) + 2
Or, you could use u-substitution to get the <em>exact</em> area under the curve from [0, 12] - but I would do as the problem says. If you want me to that, DM me.
