Answer:

h = 15 feet

Step-by-step explanation:

A right triangle is formed by the slant height, the radius of the base and h, with the slant height being the hypotenuse.

Using Pythagoras' theorem in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

Since base diameter = 16 then radius = 8

h² + 8² = 17²

h² + 64 = 289 ( subtract 64 from both sides )

h² = 225 ( take the square root of both sides )

h = [tex]\sqrt{225}[/tex] = 15

The height of the given cone will be 15 feet.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The theorem can be used to determine how steep mountains or slopes are. To calculate the distance between an observer and a location on the ground when the observer is looking down from a tower or structure. It is mostly utilized in the construction industry.

Given, A right cone has a slant height of 17 feet, and the diameter of the base is 16 feet.

Since slant height and radius of the base makes a right-angle triangle with the base of radius and hypotenuse of the slant.

Thus, from the Pythagorean theorem:

hypotenuse² = height² + base²

In our case,

Hypotenuse = slant height = 17 feet

Base = radius of base of the cone = 16/2 = 8

Thus,

17² = height² + 8²

height² = 17² - 8²

height² = 225

height = 15 feet

Therefore, the height of the given cone will be 15 feet.

The correct answer is C. -3/2

Answer:

9

Step-by-step explanation:

shorter leg = x

longer leg = x + 3

Hypotenuse = x + 6

x² + (x + 3)² = (x + 6)²

x² + x² + 6x + 9 = x² + 12x + 36

2x² + 6x + 9 = x² + 12x + 36

x²  - 6x  - 27 = 0

(x - 9) ( x + 3) = 0

x = 9 or x = -3 (rejected)

The length of the shorter leg of the right angles triangle is 9.

What is a right-angle triangle?

A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle. The right triangle or 90-degree triangle is another name for this triangle.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse

The right triangle's three sides are interconnected. The Pythagorean Theorem explains this connection. This theorem states that in a right triangle,  [tex]h^{2} = x^{2} + y^{2}[/tex];

where, h = hypotenuse; x = perpendicular side; y = base side;

Given that:

shorter leg = x

longer leg = x + 3

Hypotenuse = x + 6

⇒x² + (x + 3)² = (x + 6)²

⇒x² + x² + 6x + 9 = x² + 12x + 36

⇒2x² + 6x + 9 = x² + 12x + 36

⇒x²  - 6x  - 27 = 0

⇒(x - 9) ( x + 3) = 0

⇒x = 9 or x = -3.

x=-3 is not possible;

Hence, The length of the shorter leg = 9.

Answer:

The center of the circle is point (8 , 6)

Step-by-step explanation:

* At first lets revise how to find the mid-point between two points

- If (x1 , y1) and (x2 , y2) are the end point of a segment

- If (x , y) is the mid-point of this segment

- To find  x add x1 and x2, then divide the answer by 2

∴ x = (x1 + x2)/2

- Similar to find y add y1 and y2, then divide the answer by 2

∴ y = (y1 + y2)/2

∴ The mid-point (x , y) = [(x1 + x2)/2 , (y1 + y2)/2]

* Now lets solve the problem

- The center of the circle is the mid-point of the diameter

- Consider the center of the circle is (x , y)

- (x , y) is the mid-point of the diameter of the circle with endpoints

 (4 , 9) and (12 , 3)

- Let (4 , 9) is (x1 , y1) and (12 , 3) is (x2 , y2)

∵ x1 = 4

∵ x2 = 12

∵ x = (x1 + x2)/2

∴ x = (4 + 12)/2 = 16/2 = 8

* Similar

∵ y1 = 9

∵ y2 = 3

∵ y = (y1 + y2)/2

∴ y = (9 + 3)/2 = 12/2 = 6

∴ (x , y) = (8 , 6)

* The center of the circle is point (8 , 6)

Answer:

The center is (8,6) and radius is 5 units of the wheel

Step-by-step explanation:

On the design of the new car the steering wheel has a diameter with endpoints at (4 9) and (12,3)

End point of diameter is (4 9) and (12,3)

As we know mid point of diameter is center of circle.

Mid point formula:

[tex](x,y)\rightarrow (\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

Mid point of  (4 9) and (12,3)

[tex]Centre: (\dfrac{4+12}{2},\dfrac{9+3}{2}[/tex]

Center: (8,6)

Radius is distance between center and any one end point of diameter.

Distance formula:

[tex]R=\sqrt{(8-4)^2+(6-9)^2[/tex]

Answer: [tex]8.66in^3[/tex]

Step-by-step explanation:

The oy rocket shown is formed by a rectangular prism and a regular pyramid whose base is a square.

The volume of the rectangular prism can be calculated with:

[tex]V_{rp}=l*w*h[/tex]

Where "l" is the length, "w" is the width and "h" is the height.

You can observe that:

[tex]l=8in\\w=1in\\h=1in[/tex]

Then, you can substitute values:

[tex]V_{rp}=(8in)(1in)(1in)=8in^3[/tex]

The volume of the regular square pyramid can be calculated with:

[tex]V_p=\frac{s^2*h}{3}[/tex]

Where "s" is the lenght of a side of the base and "h" is the height of the pyramid.

You can observe in the figure that:

[tex]s=1in\\h=2in[/tex]

Substitute into the formula. Then:

[tex]V_p=\frac{(1in)^2(2in)}{3}=\frac{2}{3}in^3[/tex]

The volume of the toy rocket is the sum of the volume of the rectangular prism and the volume of the regular square pyramid. Then:

[tex]V_{toy}=8in^3+\frac{2}{3}in^3=8.66in^3[/tex]

Option a

Step-by-step explanation:

A function is a relationship between two sets called domain and co domain  where there is one output for every input. If you have more than one output for a particular input, i.e. if the mapping of elements of A to B are not unique,  then the quantities represent a relation. A graph of a relationship can be shown to be a function using the vertical line test, which says that at any point if a vertical line makes two intercepts of the curve, the curve cannot be a function.

Given are two sets with {1,2,3,4,5,6} and {2,3,4,5,6,7} where there is a mapping.

We find that while 1,3 have unique mappings 2 does not have an image at all while 4 and 5 have the same image.

Since there is an element in the I set which does not have an image, this cannot be a function.

+7 at the end means up 7

These are found using basic rules of translating equations

For this case we have to define function transformation that:

Let k> 0:

To graph [tex]y = f (x) + k,[/tex] the graph is displayed k units up.

To graph[tex]y = f (x) -k[/tex], the graph is displayed k units units down.

Let h> 0:

To graph[tex]y = f (x-h)[/tex], the graph moves units to the right.

To graph [tex]y = f (x + h)[/tex], the graph moves h units to the left.

We have [tex]y = - \sqrt [3] {x}[/tex]

It moves 7 units up and 4 to the right.

So we have to:

[tex]h = 4\\k = 7[/tex]

The shifted graphic is:

[tex]y = - \sqrt [3] {x-4} +7[/tex]

ANswer:

[tex]y = - \sqrt [3] {x-4} +7[/tex]

Answer:

For example, the function [tex]y=x^{2}[/tex] does not have a y-intercept of (0, 1). To prove this, let's make x=0, and if the value of 'y' is different from 1, then, the graph does nt have a y-intercept of (0,1):

[tex]y=x^{2}[/tex] ⇒ [tex]y=(0)^{2}[/tex] ⇒ [tex]y=0[/tex]

Therefore, the y-intercept is at (0, 0) not (0, 1).

2/10 is simplified to 1/5

The probability that a randomly selected dog is a pug is 1/5.

Given:

There are 10 dogs at the dog park.

2 dogs are pugs.

We have to find the probability that a randomly selected dog is a pug.

We know, probability is given by:

⇒ Probability = Total number of dogs which are pug / Total number of dogs at the park

⇒ Total number of dogs which are pug = 2

⇒ Total number of dogs at the park = 10

⇒ P(pug) = 2/10

⇒ P(pug) = 1/5

Therefore, the probability that a randomly selected dog is a pug is 1/5.

To find the cost of one bag of crisps, subtract the change from the amount paid for the biscuits to find the cost of the biscuits in pence, then divide by three since three bags of crisps cost the same as one pack of biscuits. The cost of one bag of crisps is 87 pence.

The student is asking for the cost of one bag of crisps in pence, given that three bags cost the same as one pack of biscuits. Tom paid the shopkeeper £3 for a pack of biscuits and received 39p as change.

First, we calculate the actual cost of the biscuits:

£3 paid - £0.39 change = £2.61 or 261p (since 1 pound equals 100 pence)

Next, we know that this cost is equal to three bags of crisps, so:

261p / 3 bags = 87p per bag

Therefore, the cost of one bag of crisps is 87 pence.
