Answer:

  Above the dashed line

Step-by-step explanation:

That y is greater than the values on the line tells you that the shading is above the line.

That the "equal to" case is not included tells you that the line is dashed.

The expression that gives you a value of 3 times larger than (820 + 220) are:

3(820 + 220)

2460 + 660

Options A and C are the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(820 + 220)

= 1040

Now,

3 x 1040

= 3120

Now,

A)

3(820 + 220)

= 3 x 1040

= 3120

B)

3(820) + 2(220)

= 2460 + 440

= 2900

C)

2460 + 660

= 3120

D)

820 x 220 x 3

= 541200

Thus,

3(820 + 220) and 2460 + 660 give the value of 3 times larger than

(820 + 220).

Step-by-step explanation:

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points. The coordinates of point (8,−2) after translation will be (13,2) and (13,4).

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

The coordinates of a point (x,y) can be translated by right 5 units and up 2 units as,

Now, the given coordinate (8, -2) can be translated as shown below,

Hence, the coordinates of point (8,−2) after translation will be (13,2) and (13,4).

Answer:

Juke's jump; by 0.35 feet

Step-by-step explanation:

Given that,

Cooper's jump rope is for [tex]4\dfrac{2}{5}[/tex] feet.

Juke's jump rope is [tex]4\dfrac{3}{4}[/tex] feet.

Cooper's jump is :

[tex]4\dfrac{2}{5}=\dfrac{22}{5}\ \text{feet}\\\\=4.4\ \text{feet}[/tex]

Juke's jump is

[tex]4\dfrac{3}{4}=\dfrac{19}{4}\\\\=4.75\ \text{feet}[/tex]

So, it is clear that Juke's jump is longer than Cooper's jump.

Juke's jump - Cooper's jump = 4.75 - 4.4

= 0.35 feet

or

So, Juke's jump is 375 feet longer.

Option 2: [tex]y - 2 = \frac{1}{3}(x-3)[/tex] is the correct answer.

Step-by-step explanation:

The equation of a line with given point(x1,y1) and slope m is given by:

[tex]y-y_1 = m(x-x_1)[/tex]

The line passes through (x1,y1)

Given

[tex](x_1,y_1) = (3,2)\\m = \frac{1}{3}[/tex]

=> x1 = 3

=> y1 = 2

Putting the values of x1, y1 and slope(m) in the point-slope form, the equation of line is:

[tex]y - 2 = \frac{1}{3}(x-3)[/tex]

Hence,

Option 2: [tex]y - 2 = \frac{1}{3}(x-3)[/tex] is the correct answer.

Step-by-step explanation:exponential function which means the value is is CONSTANTLY raised to the power

The graph the formula representing the compound interest will be exponential function.

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Given is the equation representing compound interest.

The equation representing the compound interest is -

C = P( 1 + r/n )ⁿˣ

Where -

[P] is principle amount.

[r] is rate.

[x] is time.

The exponential function is eˣ, where [x] is a variable. Similarly, we can graph the formula representing the compound interest as shown in the figure attached. The graph will be exponential in nature.

Therefore, the graph the formula representing the compound interest will be exponential function.

A 5/3

Step-by-step explanation:

The fraction closest to the golden ratio is  a. 5/3.

The golden ratio is a ratio between two numbers that approximate 1.618.

It is sometimes referred to as the golden number, the golden proportion, or the divine proportion.

It is closely related to the Fibonacci sequence, a set of numbers where each number is added to the previous one and is typically written as the Greek letter Ф.

From the given options,

5/3 = 1.66.

7/5 = 1.4.

10/8 = 1.25.

14/11 = 1.27.

So, the closest ratio is 1.6 which is 5/3.

Answer:

240

Step-by-step explanation:

According to law of exponential growth,

[tex]y=y_0e^{kt}[/tex]

Here, [tex]y_0[/tex] denotes the initial amount and k is the rate constant of the equation.

Now, the initial population is 240 bacteria.

Put [tex]y_0=240[/tex]

So,

[tex]y=240e^{kt}[/tex]

The population after 12 hours is double the population after 1 hour.

[tex]y(12)=2y(1)[/tex]

[tex]240e^{12k}=240e^{k} \\e^{12k}=e^{k} \\e^{12k-k}=1\\e^{11k}=1\\11k=log 1=0\\k=0[/tex]

(Formulae used: [tex]\frac{e^x}{e^y}=e^{x-y}\,,\,log 1=0[/tex])

So,

[tex]y=240e^{0}=240\\y=240[/tex]

Therefore,

Number of bacteria after 3 hours = 240

Answer: B

Step-by-step explanation:

To find the result of the dilation, multiply each x and y coordinate by the scale factor, which in this case, is 1.5. I started out with the coordinate P, which had an original coordinate of (-2,1). In this case, I multiplied -2 by 1.5, and 1 by 1.5 to get (-3, 1.5). Since this is multiple choice, the only one with P as (-3, 1.5) is B, so we don't have to check the others.

The answer is B.

1) Apply dilation

2)Find each one x coordinate (x,y)

3) Find the y coordinate for each one
