Answer:

The cone has a volume of approximately 982.5 cubic centimetres.

* That answer sounds off to me, but I'm not sure.  You might want to run through the logic yourself and see if you get the same results.

Step-by-step explanation:

The volume of a cone is one third that of a cylinder with the same height and base radius. In other words:

[tex]v = \pi r^{2} \frac{h}{3}[/tex]

But before using that, we need to know the value of h, height.  What we are instead given is the slant height, or the length from tip to edge.

We can use that slant height along with the base radius to get the cone height, as the three of them are the edges of a right triangle, with slant height being the hypotenuse.

To get the height then we can say

[tex]h = \sqrt{s^{2} - r^{2}}[/tex]

Where h is height, s is slant, and r is radius.

[tex]h = \sqrt{14.8^{2} - 14^{2} }[/tex]

[tex]h = \sqrt{219.04 - 196}[/tex]

[tex]h = \sqrt{23.04}[/tex]

[tex]h = 4.8[/tex]

A very squat cone indeed.

Now we can plug that and the radius into the actual cone equation:

[tex]v = \pi (14cm)^{2} \frac{4.8cm}{3}\\= \pi 196cm^2 * 1.6cm\\\approx 985.2 cm^3[/tex]

Answer:

The correct option is A

Step-by-step explanation:

Since (1, 3) are the solutions to the function g(x), then

g(x) = (x – 1)(x – 3) = x² –3x – x + 3 = x² – 4x + 3

We know that f(x) is on the same plane and f(1) = 1.

Let's take g(1) = (1 – 1)(1 – 3) = 0

Therefore, when x = 1; f = 1 and g = 0. Hence

g(1) = f(1) – 1

In order words, g(x) could be f(x) – 1.

The correct option is A

47 miles

Step-by-step explanation:

since 2 hours is 94 miles and 4 hours is 238 miles, you can take the 94 and divide by 2 to get how many miles for 1 hour.

The average rate of change will be;

⇒ 72 miles per hour

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

George is driving his car. At the end of 2 hours he has driven 94 miles, and at the end of 4 hours he has driven 238 miles.

Now,

Since, We know that;

⇒ Speed = Distance / Time

Hence, We can formulate;

⇒ The average rate of change = (238 - 94) / (4 - 2)

                                                = 144 / 2

                                                = 72

Thus, The average rate of change will be;

⇒ 72 miles per hour

Answer:

No solutions

Step-by-step explanation:

-3(x - 2) + x = -2x - 6

Distribute the left side

-3x + 6 + x = -2x - 6

Combine like terms

-2x + 6 = -2x - 6

Add 2x to both sides

6 = -6

Answer:

The measure of the 2 angles are 90° and 35°.

Step-by-step explanation:

The sum of angles in a triangle is 180°.

2x + x - 10 + 55 = 180

Simplify.

3x + 45 = 180

Find 3x.

3x = 180 - 45

    = 135

Find x.

x = 135 ÷ 3

x = 45

2x° = 45° × 2

     = 90°

(x-10)° = 45° - 10°

          = 35°

Answer: x=45

Step-by-step explanation:

2 times 45 is equal to 90

45-10 is equal to 35

55+90+35=180

The required simplified value of the given expression at x = -4 and y = 4 is 16, 385/4. Option D is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
when x = -4 and y = 4.

Expression = x⁶ - x/4y
Put x = -4 and y = 4.
= (-4)⁶ - [-4 /(4×4)]
= 4096 + 1/4
= 16385/4

The x ≤ 58 in interval notation = (-∞, 58]

In this question, we have been given an inequality  x ≤ 58

We need to write given inequality in interval notation form.

We know that, an interval notation a way to describe a subset of real numbers by the numbers that bound them.

If we draw given inequality on the number line, then it would be as shown below.

x ≤ 58 represents that, x takes all values which are less than or equal to 58.

So, the interval notation would be (-∞, 58]

Therefore, the x ≤ 58 in interval notation = (-∞, 58]

Equivalent measurements: teaspoon, ounce, pint, pound

You will find a table of equivalent measurements in the back of many cookbooks:

1 tablespoon = 3 teaspoons  

      1 cup = 16 tablespoon = 8 ounces  

    1/4 cup = 4 tablespoons  

    1/3 cup = 5 tablespoons plus 1 teaspoon  

     1 pint = 2 cups = 16 ounces  

    1 quart = 4 cups (2 pints) = 32 ounces  

   1 gallon = 4 quarts

    1 pound = 16 ounces

  1/2 pound = 8 ounces

  1/4 pound = 4 ounces

Note that a pint is 16 ounces of volume, while a pound is 16 ounces of weight. The popular rhyme "A pint's a pound, the world around" can help you remember this, but keep in mind that they're not really equivalent.

Doubling a recipe can be easy (just put in two of each measurement), but what if you need to divide a recipe in half? Here are some measurements that may help:
