The list shows the values of the changes in order, from least to greatest as Stock C, Stock A, Stock D, and Stock B which is the correct option (C).

Descending order is defined as when numbers (or other items) are arranged from the largest numbers to the least numbers, it is said to be in descending order.

Ascending order is defined as when numbers (or other items) are arranged from the least numbers to the largest numbers, it is said to be in ascending order.

We have been given four stocks during the day. The changes for the stocks are shown in the table.

-3/4, 0.7, -1, 0.2

Here the least numbers to the largest numbers, it is said to be in ascending order.

⇒ -1 < -3/4 < 0.2 < 0.7

Arrange the stock in increasing order.

Stock C, Stock A, Stock D, Stock B

Your question is incomplete, probably the missing part is:

Step-by-step explanation:

it grows exponentially.

a negative exponent like

n^-a

means only

1/(n^a)

-3 1/3³ = 1/27

-2 1/3² = 1/9

-1 1/3¹ = 1/3

0 3⁰ = 1

1 3¹ = 3

2 3² = 9

3 3³ = 27

so, 3^x comes from very small but positive values, and grows very fast (much faster than x itself and with ever increasing speed hence "exponentially") to very large and still positive numbers.

Time taken by car to pass the truck in the same direction from the time the car enters the highway is approximately12.54 minutes with a truck speed 60mph and a car 67mph.

As given in the question,

Speed of a truck=60mph

⇒60 minutes = 60miles

⇒14 minutes = (60/60)×14

                     = 14 miles

Car speed =67mph

67 miles=60minutes

⇒1miles = (60/67) minutes

⇒14miles = (60/67)×14

                ≈12.54 minutes (approximately)

Therefore, time taken by car to pass the truck in the same direction from the time the car enters the highway is approximately12.54 minutes with a truck speed 60mph and a car 67mph.

Answer:

Step-by-step explanation:

Screen B is wider

Answer:

64 ft^2

Step-by-step explanation:

It is a square to start, so each side = x

then     (x+7 )    *    ( x -2)    = 90

          x^2 + 5x -14 = 90

           x^2 + 5x - 104 = 0         factor or use Quadratic Formula to fin x = 8 ft

Original area is then 8 x 8 = 64 ft^2  

The value of x from the given diagram is 64 degrees

A line is defined as the shortest distance between two points. From the given diagram, we have that the line AB bisects FAB, hence;

<FAB = <CAB = 58 degrees

Also since the sum of angles on a straight line is 180 degrees, hence;

58 + 58 + x = 180

116 + x = 180

x = 180 - 116

x = 64 degrees

Hence the value of x from the given diagram is 64 degrees

Step-by-step explanation:

Your equations are in the slope-intercept form of a line.  The equations are make up of a slope and a y-intercept.

y = mx + b  The m is the slope (the steepness of the line) and b is the y-intercept.  This is where the line crosses the y axis.

I would start with the y intercept.  Look at the first equation

y = x -8  The -8 tells us that this graph crosses the y axis at (0,-8)  From that point, we will use the slope.  The slope is the number before the x.  If we do not see a number than it is 1.  We want to make this a fraction. What is 1 as a fraction?  1/1  This means that from -8 where the graph crosses the y axis we will follow the pattern of up one, one to the right.

Let's look at the second graph

y = -x + 5.  This tells us that we cross the y axis at (0,5).  Our slope is -1.  What is -1 as a fraction?  -1/1.  This means that we will move down 1 and right one.  We will follow that pattern.

Let's look at the third graph

y = 3/4x - 1  We cross the y axis at (0,-1)  From that point we move up 3 and right 4.

y = 3 means that no matter what x is, y will be -3.  This creates a horizontal line.

x = -4 means that not matter what y is, x will be -4.  This creates a vertical line.

We have to find the range of the set of scores.

What is Range of set?

The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set.

Now,

The highest number = 20

The lowest number = 7

The amount Julie has to spend after buying the chair is $303.

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.

As per the given data:

We are given the details of the transactions that Julie did.

We have to find out the remaining amount of money that is left with Julie after the transactions.

Initial amount that Julie had to spend (A) = $237

Answer:

3a + (5b + 7c)

Step-by-step explanation:

The answer cannot be 3a(5b +7c) because when the number is immediately before the brackets, it signifies multiplication. therefore the 3a(5b+7c) would be equivalent to 15ab+21ac

the answer cant be 7c(5b+3a) because of the same explanation as the one above, therefore 7c(5b+3a) would be equivalent to 35cb+21ca

the answer finally cant be 8ab+7c because it means that one added 3a and 5b giving you 8 but it cannot be ab because ab is equivalent to a×b, hence, one cant put a multiplied algebraic expression with an added number

The equation equivalent to the the expression (3a + 5b) + 7c is 3a + (5b+7c). Hence, the first option is the correct one.

In mathematics, expressions are assertions that must contain at least two words with variables or terms with numbers in them, or both, and connect them with an operator. It is possible for the mathematical operators to be addition, subtraction, multiplication, or division.

For instance, the equation x + y has the terms x and y with an addition operator in between. Numerical expressions, which just contain numbers, and algebraic expressions, which also include variables, are the two types of expressions used in mathematics.

The first option is correct because it does not affect the main equation rest are not the same as the equation.

For example, let's take the second equation :

3a (5b + 7C)

After solving this option we get 15ab + 21 ac so it is incorrect because it changed the main expression.

Given a point P(x,y), its dilation about the origin by a scale factor of k maps the point to a point P'(kx,ky).

If we are given the dilated point, then we can find the original point by dividing by the scale factor.

Triangle ABC was dilated by a scale factor of 3 about the origin mapping it to triangle A'B'C' with vertices A'(-1/3), B'(4/,2), and C(0/-5).

The coordinates of triangle ABC are:

A=(-1/3,3/3) = (-1/3)

B=(4/3,2/3) = (4/3,2/3)

C=(0/3,-5/3) = (0/3,-5/3)

The segment addition postulate is a geometry axiom that states that a line segment, divided into a number of smaller segments, has the length given by the sum of the lengths of the segments.

Number line:

Number line used for visual representation of numbers on a straight line.

Given:

Here we need to locate and plot √15 on a number line.

Steps for the construction:

Step 1) Draw a line AB that is 15 in length, and then add 1 to C so that the distance from A to C is 16.

Step 2) From the midpoint of A C on the line, use your compass and make a half circle from A to C.
