Answer:

If graph of any function going towards down in a particular interval. Then , function is decreasing in that interval.

From x = -∞ to x = a , function is positive and decreasing.

Here, a graph is attached in the question.

We know that, if graph of any function is going towards down in particular interval. Then function is decreasing in that particular interval.

If graph of any function is going towards up in particular interval. Then function is increasing in that particular interval.

In given graph. it is observed that in interval x = -∞ to x = a , graph of function is above x - axis and graph is going towards down. Therefore, in given interval function is positive and decreasing.

Answer:

1/6

Step-by-step explanation:

The square cake can be distributed in such a way that each person out of 15 guest may get 8  [tex]inch^{3}[/tex], with the least amount left over .

The Correct option is (1).

The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units.

First find the volume of square cake,

= 8 x 8 x 2

=128 [tex]inch^{3}[/tex]

Now there are total 15 guests, Each of get

=[tex]\frac{128}{15}[/tex]

=  8.533 [tex]inch^{3}[/tex]

 2.Volume of round cake (d= 6 inch, r=3 inch, h= 3 inch)

Volume= [tex]\frac{1}{3} \pi r^{2} h[/tex]

= [tex]\frac{1}{3} *3.14 *3^{2}* 3[/tex]

=[tex]3.14*9[/tex]

=28.26  [tex]inch^{3}[/tex]

Now there are total 15 guests, Each of get

=[tex]\frac{28.26}{15}[/tex]

= 1.884[tex]inch^{3}[/tex]

 3.Volume of round cake (d= 8 inch, r=4inch, h= 3 inch)

Volume= [tex]\frac{1}{3} \pi r^{2} h[/tex]

= [tex]\frac{1}{3} *3.14 *4^{2}* 3[/tex]

=[tex]3.14*16[/tex]

=50.24   [tex]inch^{3}[/tex]

Now there are total 15 guests, Each of get

=[tex]\frac{50.24}{15}[/tex]

=  3.349 [tex]inch^{3}[/tex]

 4. Volume = l x b x h

= 6 x 9 x 2

=108 [tex]inch^{3}[/tex]

Now there are total 15 guests, Each of get

=[tex]\frac{108}{15}[/tex]

=  7.2[tex]inch^{3}[/tex]

According to question each person may get 8 [tex]inch^{3}[/tex].

Only the square cake can be distributed in such a way that each person may get 8 [tex]inch^{3}[/tex], with the least amount left over .

The number of people at the party now is 23.

The percentage of a number is the fraction of that number multiplied by 100. Percentages are represented with this sign: %.

3 friends arrive at a party. The percentage of people increase by 20%.This can be represented with this equation:

p x 20% = 3 people

where p is the number of people at the party before the friends arrived.

p = 3 / 20%

p = 3 / 0.20

p = 15 people

The total number of people at the party now : 15 + 8 = 23.

Answer:

The last option: 6,000 toothpicks.

Step-by-step explanation:

The formula I used: (2L) (2W) (2H)

If a jumbo sized box is made by doubling the length, width, and height then each measurment will be doubled so length x2, width x2, height x2 so therefore those added up would be 8. Then just do 8 times the volume. 8 x 750 = 6,000.

Answer: The answer is D. the last option

Step-by-step explanation:

The correct answer is option d) The graph is the radical function, y = √x shifted right 1 unit and up 4 units.

The original function is y = √(x - 1) + 4, which represents a radical function.

This function involves taking the square root of the quantity (x - 1) and then adding 4 to the result.

By shifting the function right 1 unit, we are replacing x with (x - 1). This means that the graph will be shifted horizontally by 1 unit to the right compared to the standard square root function.

By shifting the function up 4 units, we are adding 4 to the output of the square root function.

This means that the graph will be shifted vertically by 4 units compared to the standard square root function.

Therefore, the graph of the function y = √(x - 1) + 4 is the radical function y = √x shifted right 1 unit and up 4 units.

Step-by-step explanation:

An asymptote of a curve is a line which the curve gets infinitely close to, but never touches.

From inspection of the graph, we can see there is a horizontal and a vertical asymptote, both indicated by the dashed straight lines.

The horizontal asymptote is y = 2  (blue dashed line)

The vertical asymptote is x = 2  (red dashed line)

Therefore, the asymptotes are:  x = 2, y = 2

The height of the green pyramid constructed  by Natalie while playing with magnetic building tiles is 26.25 cm.

The volume of the orange pyramid is calculated as follows;

V = ¹/₃Ah

where;

V = ¹/₃ x (7²) x 5

V  = ¹/₃ x (245 cm³)

Voume = 21 x [¹/₃ x (245 cm³)]

Volume = 1,715 cm³

V = ¹/₃Ah

3V = Ah

h = 3V/A

h = (3 x 1715) / (14²)
