Answer:

[tex]Volume=288in^{3}[/tex]

Step-by-step explanation:

Given

Base Cubes =36

Layers = 8

The number of base cubes represents the base area and the number of layers represents the height of the prism.

So, the volume is calculated as:

Volume = Base Cubes * Layers, i.e Base Area * Heights

Volume = [tex]36*8[/tex]

Volume = [tex]36in^{2} * 8 in[/tex]

Volume = [tex]288in^{2}[/tex]

Given:

The graph of the system of inequalities.

To find:

The system of inequalities.

Solution:

From the given graph it is clear that the first line passes through the points (0,2) and (1,-1). So, the equation of the boundary line is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-2=\dfrac{-1-2}{1-0}(x-0)[/tex]

[tex]y-2=-3x[/tex]

[tex]y=-3x+2[/tex]

The shaded region lies above the line and the boundary line is a solid line. So, the sign of inequality must by ≥.

[tex]y\geq -3x+2[/tex]

The second line passes through the points (0,-2) and (3,0). So, the equation of the boundary line is:

[tex]y-(-2)=\dfrac{0-(-2)}{3-0}(x-0)[/tex]

[tex]y+2=\dfrac{2}{3}x[/tex]

[tex]y=\dfrac{2}{3}x-2[/tex]

The shaded region lies above the line and the boundary line is a solid line. So, the sign of inequality must by ≥.

[tex]y\geq \dfrac{2}{3}x-2[/tex]

Therefore, the system of inequalities contains two linear inequalities [tex]y\geq -3x+2[/tex] and [tex]y\geq \dfrac{2}{3}x-2[/tex].

Answer:

(C) j/j+80 and 36/k+36

Step-by-step explanation:

From the table attached :

Total Email (positive + negative) = j + 80

Number of positive Emails = j

Fraction of positive emails = (number of positive  / total number of emails) = j / (j + 80)

Total phone calls  (positive + negative) = 36 + k

Number of positive Emails = 36

Fraction of positive emails = (number of positive  / total number of emails) = 36 / (k + 36)

Answer:

It will take approximately 68.2 years for the Caribou population to reach 21,000.

Step-by-step explanation:

The population P of Caribou in the Yukon is modeled by P=6x²-120x+1250 where x is the number of years from today.

If the population P of Caribou in the Yukon is 21000, then, replacing you get:

21000= 6x²-120x+1250

So:

0= 6x²-120x+1250 -21000

0= 6x²-120x - 19750

This is a quadratic function of the form: 0= ax²+ bx +c, where: a=6, b= -120 and c=-19750

To solve a quadratic function and determine the value of x you can use the expression:

[tex]x1,x2=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}[/tex]

Replacing the values ​​of a, b and c and solving you get:

[tex]x1,x2=\frac{-(-120)+-\sqrt{(-120)^{2}-4*6*(-19750) } }{2*6}[/tex]

[tex]x1,x2=\frac{120+-\sqrt{14400+474000 } }{12}[/tex]

[tex]x1,x2=\frac{120+-\sqrt{488400 } }{12}[/tex]

[tex]x1,x2=\frac{120+-698.86 }{12}[/tex]

So:

[tex]x1=\frac{120+698.86 }{12}[/tex]

x1= 68.24 ≅ 68.2

and

[tex]x2=\frac{120-698.86 }{12}[/tex]

x2= -48. 24 ≅ -48.2

As time cannot be negative, it will take approximately 68.2 years for the Caribou population to reach 21,000.

Answer:

Black socks pairs = 7

Brown socks pairs = 3

White socks pairs = 8

P(not black) = ?

First, you need to add the brown & white socks pairs,

[tex]3 + 8 = 11[/tex]

Then you need to add the total number of socks pairs,

[tex]7 + 3 + 8 \\ = 7 + 11 \\ = 18[/tex]

P(not black)

[tex] = \frac{11}{18} [/tex]

Step-by-step explanation:

solution given:

total pair of socks[S]=(7+3+8)=18

total pair of black socks[B]=7

total pair of brown socks [C]=3

total pair of white socks[W]=8

total no of orange marbles[O]=2

now

the P( not black) =?

we have

P( not black) =1-[tex] \frac{n[B]}{n[S]} [/tex]

P( not black) =1-[tex] \frac{7}{18} [/tex]

P( not black) =[tex] \frac{18-7}{18} [/tex]

P( not black) =[tex] \frac{11}{18} [/tex]

so 11/18 is a required probabilty.

Step-by-step explanation:

g(x) =(1/4 x)²

g(x)  = 4x² will be the equation of the parabola.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given, two parabolas f(x) and g(x),

From the general equation of the parabola,

y = a(x – h)² + k or x = a(y – k)² +h.

Here (h, k) denotes the vertex.

As we can see in our case, the vertex is (0, 0)

Thus, the equation of the parabola will be

y = ax²

Since the given parabola passes through the point (1, 4)

Substitute the values,

4 = a(1)²

a = 4

therefore, the equation of the parabola g(x) will be,

g(x)  = 4x²

Answer:

6.63 pounds

Step-by-step explanation:

Total pounds of mixture = 20

The contents of the mixture are; peanuts and almonds. Of which;

Peanuts cost = $2.95 per pound

Almonds cost = $5.95 per pound

The mixture cost = $4.00 per pound

Total cost of contents of the mixture = $8.90

The pounds of peanuts = [tex]\frac{2.95}{8.90}[/tex] x 20

                     = 6.63

Therefore, 6.63 pounds of peanuts was used in producing 20 pounds of the mixture.

The number is -12 in the inequality x + 4y ≥ ?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given is a system of linear inequalities represented by the graph [attached]

We need to find the missing number,

y ≥ 2x – 2 and x + 4y ≥ ?

The linear equation with slope m and intercept c is given as follows.

y = mx + c.

The formula for slope of line with points (x₁, y₁) and (x₂, y₂) can be expressed as,

m = y₂ - y₁ / x₂ - x₁

The orange line intersects y-axis at (0, -2), therefore the y-intercept is -2.

The orange line intersects the points that are (1, 0) and (0, -2).

The slope of the line can be obtained as follows,

m = 2,

The slope of the line is m = 2.

Therefore, the orange line is y ≥ 2x – 2.

The blue line intersects y-axis at (0, -3), therefore the y-intercept is -3.

The blue line intersect the points that are (-4, -2) and (0, -3).

The slope of the line can be obtained as follows.

m = -1/4

The inequalities is x + 4y ≥ b passes through the point (0, -3).

0 + 4(-2) ≥ b

-12 ≥ b

Hence the number is -12 in the inequality x + 4y ≥ ?

Answer:

y=3,000(0.985)^x

y=1,500(1.012)^x

Step-by-step explanation:

System of equations  Brandon can use for  two location are y= 3000[tex](0.985)^{x}[/tex] and y =[tex]1500(1.012)^{x}[/tex]

Profit and loss percentage are used to refer to the amount of profit or loss that has been incurred in terms of percentage.

According to question

Brandon is analyzing the profits from two of his restaurant locations.

where

x = number of week

y = the profit

1st restaurant : showed a profit of $3,000 in the first week of the year but

has a showed a steady decrease in profits of 1.5% each week since then

So in equation we can write it as

y= [tex]3000(1 - 0.015)^{x\\}[/tex]

y= 3000[tex](0.985)^{x}[/tex]

2nd restaurant : showed a profit of $1,500 in the first week of the year and has showed a steady increase in profits of 1.2% each week since then.

So in equation we can write it as

y = [tex]1500(1+0.012)^{x}[/tex]

y =[tex]1500(1.012)^{x}[/tex]

Hence, system of equations can Brandon use to determine the x and y form the two location are y= 3000[tex](0.985)^{x}[/tex] and y =[tex]1500(1.012)^{x}[/tex]
