Luke tried to use Cavalieri's principle to show that the two figures have the same volume. The base areas are the same. Therefore, corresponding cross-sections have the same area. The prisms have the same height. So the volumes must be the same. What is the first mistake Luke made?
Answers
The error Luke made when trying to use Cavalieri's principle to show that the two figrues have the same volume is stating that: "corresponding cross-sections have the same area" which is NOT TRUE.
What is the Cavalieri's Principle?The Cavalieri's principle was named after Bonaventura Cavalieri. The Cavalieri's principle states the volume of two figures are the same if they have the same height and teh same cross-sectional area at every point along the height.
Thus, the two figures have entirely different cross-sectons. Their areas would be diffrent.
Therefore, the error Luke made when trying to use Cavalieri's principle to show that the two figrues have the same volume is stating that: "corresponding cross-sections have the same area" which is NOT TRUE.

The temperature in a room at midnight is 20 degrees Celsius. Over the next 24 hours, the temperature changes at a rate modeled by the differentiable function H, where H(t) is measured in degrees Celsius per hour and time t is measured in hours since midnight. Which of the following is the best interpretation of 0 6 H(t) dt?
(A) The temperature of the room, in degrees Celsius, at 6:00 A.M.
(B) The average temperature of the room, in degrees Celsius, between midnight and 6:00 A.M.
(C) The change in the temperature of the room, in degrees Celsius, between midnight and 6
(D) The rate at which the temperature in the room is changing, in degrees Celsius per hour, at 6:00 A.M.
Answers
It will represent the change in temperature between midnight and 6, the correct option is C.
Which is the best interpretation of ∫H(t)*dt?
H(t) is the rate at which the temperature changes. So, if we integrate H(t), we will get the change of temperature.
In this case, we have:
[tex]\int\limits^6_0 {H(t)} \, dt[/tex]
This will give the change in temperature between 6:00 AM (represented by the 6) and midnight (represented with the 0).
So the correct option is C.

The vertical height in feet of a projectile on a planet in our solar system at a given time t in seconds is represented by the function h (t) = -4^2 + 24t Re-write h(t) in the form h(t) = a(t – h)^2 + k and determine the maximum height of the projectile. Show all work.
Answers
h (t) = -4t^2 + 24t = -4 (t² - 6t)
= -4 [(t - 3)² - 3²]
= -4 (t - 3)² + 36
max (3 ; 36)
(t - 3)² = t² - 2*t*3 + 3² = t² - 6t + 9
so it's why t² - 6t = (t - 3)² - 9
The maximum height of the projectile is 36 feet.
It is given that the projectile on a planet in our solar system at a given time t in seconds is represented by the function:
[tex]\rm h(t) = -4t^2+24t[/tex] can be written as a function:
[tex]\rm h(t) = a(t-h)^2+k\\[/tex]
It is required to determine the maximum height of the projectile.
What are maxima and minima?Maxima and minima of a function are the extrema within the range, in other words, the maximum value of a function at a certain point is called maxima and the minimum value of a function at a certain point is called minima.
The given function:
[tex]\rm h(t) = -4t^2+24t[/tex] for the maximum height of the projectile differentiate the given function with respect to 't' and equate it to zero.
[tex]\rm h(t) = -4t^2+24t\\[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = \frac{\mathrm{d} }{\mathrm{d} x}(-4t^2+24t)\\[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = \frac{\mathrm{d} }{\mathrm{d} x}(-4t^2)+\frac{\mathrm{d} }{\mathrm{d} x}(24t)\\[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = -8t+24\\[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = 0 \Rightarrow-8t+24=0\\[/tex]
[tex]\rm -8t+24=0\\\rm t= 3 \ sec[/tex]
Here, [tex]\rm \frac{\mathrm{d}^2 }{\mathrm dx^2} \leq 0[/tex]
It means that at t=3, we get the maximum height of the projectile.
[tex]\rm h(3)= -4(3)^2+24(3)\\\rm h(3) = -36+72\\\rm h(3)= 36 \ Feet[/tex]
Thus, the maximum height of the projectile is 36 feet.

When a construction worker is on a platform 10 feet above the ground, we can describe her elevation as +10 feet.
A construction worker digs down to 30 feet below the platform. What is her elevation?
Answers
It is 30 feet BELOW the platform, so the number is -20 because the platform is 10 feet above ground level.
Her elevation is - 20 because she is 10 feet above ground level, which is 10, and she digs 30 feet down so 10 - 30 is -20.
Hope this helps. :)
Answer:
-20 feet
Step-by-step explanation:
Ok, if the construction worker is first at 10 feet above the ground. If the construction worker goes 30 feet below the platform, the equation can be this: 10 - 30 = e or elevation. Remember that it states that the construction worker digs 30 feet below the platform, and not below the ground. Because 10 - 30 is -20, we know that the construction worker's elevation is -20.
