Complete question :

In the evening, the temperature is 2828 degrees. By midnight it has dropped 3131 degrees lower. Between midnight and 4 am, it goes down 66 more degrees. Then, by 9 am, the temperature goes up 3030 degrees. Find the final temperature.

Answer:

-38°

Step-by-step explanation:

Evening temperature = 28°

By midnight = 31° lower

4am = 66° lower

9 a.m = 30° higher

Temperature at midnight :

28° - 31° = - 2°

Temperature at 4 a.m:

-2° - 66° = - 68°

Final temperature at 9a.m :

-68° + 30° = - 38°

The temperature at 9a.m is - 38°

What is the range, min, and max of the function f(x)=13-20x-x²-3x⁴
Naya [18.7K]

Answer:

  • range: (-∞, 29.4336]
  • min: -∞
  • max: 29.4336

Step-by-step explanation:

I found these using a graphing calculator. (See attached)

The function is a polynomial of 4th degree with a negative leading coefficient. (The coefficient of the 4th-degree term is -3.) Therefore, it opens downward and has a range that extends to -∞. This function only has one global maximum and no local minimum.

_____

The maximum can be found by solving the cubic equation that results from taking the derivative of this function and finding the root of that:

  df/dx = -12x^3 -2x -20 = 0

There are formulas for the solutions of a cubic, but the one negative real root of this cubic can be found easily with a graphing calculator using iteration:

  x ≈ -1.13879908894.

Dividing by -2, the above derivative function can be written as ...

  g(x) = 6x^3 +x +10

The one real zero of it can be found using Newton's Method iteration.

The Newton's Method iterator function is

  h(x) = x - g(x)/g'(x)

where g'(x) is the derivative of g(x), often available as a function on the graphing calculator.

The starting value for the iteration can be the x-value obtained from the graph: -1.139. It only takes about 2 or 3 iterations to find x to the precision of the calculator: x = h(h(x)). This x is the x-coordinate of the maximum, so f(x) is the maximum value: 29.4335546516.

__

The attachments show the function definitions and their use for finding the maximum of f(x) using a TI-84 calculator. Y₁ is the function f(x); Y₂ is its derivative, shown above as g(x). Y₃ is the iterating function, shown above as h(x). The nDeriv( ) function is a calculator function that finds the numerical derivative of its argument.

Judy has a sugar cone and wants to know how many cubic inches of ice cream it will hold if it is filled completely to the top of
stepladder [879]
The answer is 10.6 cubic inches.

The formula for a volume of the cone is V = 1/3 π r² h,
where:
V - the volume of the cone,
<span>r - radius of the cone base,
</span>h - height of the cone.

It is given:
h = 4.5 in
r = 1.5 in.
π = 3.14

If:
<span>V = 1/3 π r² h,
</span>Then:
V = 1/3 × 3.14 × (1.5 in)² × 4.5 in
V = 1/3 × 3.14 × 2.25 × 4.5 in³
V = 10.6 in³

Therefore, Judy's sugar cone can hold 10.6 <span> in³.</span>
