Answer:

312π mm3

Step-by-step explanation: yes

The required volume of the composite figure of the sphere on the top of the cone is 312π mm³. Option c is correct

The sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The height of the cone is 14 millimeters. The volume of the composite figure is to determine.

Volume is defined as the ratio of the mass of an object to its density.

Volume of composite figure =  Volume of semi-sphere  + Volume of cone
                                              =   2/3πr³ + 1/3πr²h
                                              =  2/3*6³π + 1/3*6²*14π
                                              =   312π mm³

Thus, the required volume of the composite figure of the sphere on the top of the cone is 312π mm³.

Answer:

74

Step-by-step explanation:

Both angles x and 106 are supplementary which means

x+106=180

x=180-106

x=74

Answer:

74°

Step-by-step explanation:

In the image you have provided, angle 'x' and 106° are co-interior angles. This mean that both the angles add up to 180°. We can easily identify co-interior angles because the angles would be inside. The other types of angles you can get is vertical and corresponding. Using the information in the second sentence we can set up an equation,

⇒ Form an equation

→ x + 106 = 180

⇒ Minus 106 from both sides to isolate x

→ x = 74°

The values of angle x is 74°

Answer: You find it by using slope

Step-by-step explanation

If the graph is rising from left to right, like climbing a hill, the slope is positive (on a graph, you could count up y units divided by right x units). If it is going down from left to right (like sliding down a hill), the slope is negative (on a graph you have to count down y units and right x units).

ex: y = 5x + 3 is an example of the Slope Intercept Form and represents the equation of a line with a slope of 5 and and a y-intercept of 3. y = −2x + 6 represents the equation of a line with a slope of −2 and and a y-intercept of 6.

Answer: x = 2, -4

Step-by-step explanation:

The zeros of a function are where the function crosses the x-axis, in this case, the function crosses the x-axis at 2 and -4, so 2 and -4 are the zeros of this function.

Hope this helps.

Answer:

By definition, the zeros of a function f(x) are all the values x for which f(x) = 0. In other words, the zeros of a function f(x) are the intersections of the graph of f(x) with the axis of x. Therefore, to identify the zeros of the function shown, identify the values of x in which the graph intersects the horizontal axis.

Answer:

B.g(x) = RootIndex 3 StartRoot x minus 3 EndRoot + 4

Step-by-step explanation:

Equation, graphed along with the parent function is g(x) = ∛(x-3) + 4

The correct option is B.

The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x).

Given,

Graph of a parent function

and equation is graphed along with the parent function

Parent function

f(x) = ∛x

By the graph,

There is 3 unit horizontal shift to positive side, and 4 unit vertical shift to upwards in parent function

Thus, function drawn along with it is

g(x) = ∛(x-3) + 4

Hence, g(x) = ∛(x-3) + 4 is the equation, graphed along with the parent

The value of the equation is 1.

The equation given is (x-1)/(x-1) = 1.

To determine the solution, we can simplify the equation by canceling out the common factor (x-1) on both sides:

(x - 1)/(x - 1) = 1

1 = 1

The simplified equation 1 = 1 is always true for any value of x.

Therefore, the original equation is true for all values of x, except when x = 1.

When x = 1, the equation is undefined because the denominator becomes zero, resulting in division by zero.

Hence the value of the equation is 1.

Answer:

212.5 cm² and 120 in²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

(4)

Here b = 25 and h = 17, thus

A = 0.5 × 25 × 17 = 212.5 cm²

(5)

Here b = 12 and h = 20, thus

A = 0.5 × 12 × 20 = 6 × 20 = 120 in²

Answer:

i think its 25 because like if 72 is the shaded part then it can't be the answer 100 wouldn't be the answer because it is too high and 20 wouldn't be the answer because it is too low so 25 is my reasonable answer.

Step-by-step explanation:

Since the area to me is 25 then we would do 360 x 25 = 9000

the you do 9000 / 36 i got 36 by doing 360 / 10

After that you you do 9000 / 36 which gives you 2.5

Last i did 2.5 x 10 which gave me 25

Answer:

See Explanation and Attachment

Step-by-step explanation:

Your question is incomplete as the diagram of the polygon is not attached.

However, I'll give a general guide to calculate the area of a regular polygon.

If you apply these steps, you'll be able to solve your question.

The area of a regular polygon is calculated this.

Area = ½ap

Where a represents the apothem of the polygon and p represents the perimeter of the polygon.

The term "apothem" means the distance between the centre of the polygon and the base of the polygon.

Take for instance, the attachment below.

The polygon is a regular hexagon (it has 6 sides)

The apothem, a = 8.2 ft

The perimeter, p = The sum of all sides of the hexagon

p = (7.6 + 7.6 + 7.6 + 7.6 + 7.6 + 7.6)ft

p = 45.6 ft

Hence, the area of the polygon

A = ½ap becomes

A = ½ * 8.2 * 45.6

A = ½ * 373.92

A = 186.96ft²

Answer: b

Step-by-step explanation:

Answer:

A. x = 5, -3

Step-by-step explanation:

The quadratic equation/formula is:

[tex]x = \frac{-b+- \sqrt{b^2 - 4ac} }{2a}[/tex]

The setup is:

[tex]ax^2+bx+c=0[/tex]

[tex]4x^2 - 8x -60=0[/tex]

Plug in the numbers according to the letter associated:

[tex]x = \frac{8+-\sqrt{-8^2-4(4)(-60)} }{2(4)}[/tex]

[tex]x = \frac{8+-\sqrt{1024} }{8}[/tex]

[tex]x = \frac{8+-32}{8}[/tex]

Solve for addition and subtraction:

[tex]x = \frac{8+32}{8}[/tex]                                                                              [tex]x = \frac{8-32}{8}[/tex]

[tex]x = \frac{40}{8}[/tex]                                                                                  [tex]x = \frac{-24}{8}[/tex]

x = 5                                                                                      x = -3

Answer:

r = 11

Step-by-step explanation:

Given

The above table

y = rx

Required.

Find the constant of proportionality.

To find the constant of proportionality, we simply test the values of y and x in the given formula.

Using y = rx

Make r the subject of formula by dividing both sides by x

y/x = rx/x

y/x = r

r = y/x

From the above table of data;

When x = 2, y = 22

So, r = 22/2

r = 11

When x = 7, y = 77

So, r = 77/7

r = 11

When x = 9, y = 99

So, r = 99/9

r = 11

Notice that r maintains the value of 11 all through.

Hence, the constant of proportionality, r for the above data is 11
