Ranked least to greatest:

l 125 l

l -127 l

l -132 l  

(the absolute value of 125, the absolute value of -127, and the absolute value of -132)

Step-by-step explanation:

Absolute value are the bars around a number that essentially is the distance of that number from ZERO. An easy way to visualize this is through a numberline. Therefore, even negative numbers under the absolute value of, become positive since the distance from zero can't be negative.

Looking at the problem, descending means going down in this case it symbolizes the negative.

So putting absolute value bars around each number we know that the absolute value of 125 is 125.. The absolute value of -132 is 132. The absolute value of -127 is 127.

Ordered from least to greatest we get: 125, 127, 132.

The average amount of soda consumed per person in the US from 1990 to 2010 can be modeled by the following equation, where x is the number of years since 1990. f(x) 5.852x^4-0.002x³ + 0.006x² + 0.029x + 47.855 Find the average rate of change for each time interval. a. 1990 to 1996 b. 1990 to 2000 c. 2005-2010​

Answers

Using it's concept, the average rates of change are given as follows:

a. 1264.03 soda per person per year.

b. 5851.89 soda per person per year.

c. 128010.89 soda per person per year.

What is the average rate of change of a function?

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For this problem, the function is given as follows:

f(x) = 5.852x^4 - 0.002x³ + 0.006x² + 0.029x + 47.855.

From 1990 to 1996, we have t = 0 to t = 6, hence:

f(0) = 47.855.f(6) = 5.852(6)^4 - 0.002(6)³ + 0.006(6)² + 0.029(6) + 47.855 = 7632.01.

Hence the rate is:

(7632.01- 47.855)/6 = 1264.03.

1264.03 soda per person per year.

From 1990 to 2000, we have t = 0 to t = 10, hence:

f(0) = 47.855.f(10) = 5.852(10)^4 - 0.002(10)³ + 0.006(10)² + 0.029(10) + 47.855 = 58566.75.

Hence the rate is:

(58566.75 - 47.855)/10 = 5851.89.

5851.89 soda per person per year.

From 2005 to 2010, we have t = 15 to t = 20, hence:

f(15) = 5.852(15)^4 - 0.002(15)³ + 0.006(15)² + 0.029(15) + 47.855 = 296300.39.f(20) = 5.852(20)^4 - 0.002(20)³ + 0.006(20)² + 0.029(20) + 47.855 = 936354.84.

Hence the rate is:

(936354.84 - 296300.39)/5 = 128010.89.

128010.89 soda per person per year.

Answers

The coordinates of the point 7/10 of the way from A to B is (2.4, 4.2)

How to find the coordinates of the point 7/10 of the way from A to B?

On the coordinate plane, we have the following coordinates

A = (-3, -8)

B = (11, 6)

The point 7/10 can be represented using the following ratio

m : n = 7 : 3

The coordinates of the point 7/10 of the way from A to B is calculated as

Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)

This gives

Point = 1/(7 + 3) * (3 * 11 + 3 * -3, 11 * 6 + 3 * -8)

Evaluate

Point = 1/10 * (24, 42)

This gives

Point = (2.4, 4.2)

Hence, the coordinates of the point 7/10 of the way from A to B is (2.4, 4.2)

During a game of​ one-on-one, Rodney and Justin scored 39 points altogether. If Justin lost the game by 1 ​point, how many points did each player​ score? Use a system of linear equations in two variables to solve the problem

Answers

The points scored by Rodney is 20 points.

The points scored by Justin is 19 points.

How many points did each player score?

x + y = 39 equation 1

x - y = 1 equation 2

Where:

x = points scored by Rodney

y = points scored by Justin

In order to determine the points scored by Justin, take the following steps:

Subtract equation 2 from equation 1 :

2y = 38

Divide both sides of the equation by 2

y = 38/2

y = 19 points

To determine the value of x, substitute for y in equation 2

x - 19 = 1

Triangle CDE, with vertices C(-4,2), D(-3,7), and E(-7,6), is drawn inside a rectangle,

Answers

Area of triangle ΔCDE  with the vertices C( -4 , 2 ), D( -3 , 7 ), and E( -7 , 6 ) is 9.5 square units.

We have a triangle ΔCDE with the vertices C( -4 , 2 ), D( -3 , 7 ), and E( -7 , 6 ). To calculate the area of triangle when its vertices are given we have the formula as shown below,

Area of triangle ΔCDE = [tex](1/2)(x_{1} (y_{2} - y_{3} ) + x_{2} (y_{3} -y_{1} ) + x_{3} (y_{1} -y_{2} ))[/tex]

Here, [tex]x_{1}[/tex] = -4 , [tex]x_{2}[/tex] = -3 ,[tex]x_{3}[/tex] = -7 , [tex]y_{1}[/tex] = 2 , [tex]y_{2}[/tex] = 7 and [tex]y_{3}[/tex] = 6

On substituting the above values in the formula of area of triangle , we will get

Area of triangle ΔCDE = (1/2)( -4 ( 7 - 6 ) + ( -3 ) ( 6 - 2) + (-7 ) ( 2 - 7 ))

Area of triangle ΔCDE = (1/2) ( - 4 - 12 + 35 )

Area of triangle ΔCDE = 19/2

Area of triangle ΔCDE = 9.5 square units

b) What is P(1) if Rhonda chooses spinner A? P(1|B) = __

c) Choose the correct symbol to make the statement true

Answers

Using probability we get (a) P(1|A) = 1/2 and (b)P(1|B) =3/4 , hence P(1|A) ≠ P(1|B).

Probability is the study of chance . The part of mathematics known as probability deals with fractional representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, 0 denotes the event's impossibility and 1 denotes certainty.

Probability is calculated by the fraction possible outcomes ÷ total outcomes

a) The first spinner has the total 4 sections. so there are 4 total outcomes.

Favorable outcome = 1

Total number of favorable outcome=2

Probability P(1|A) = favorable outcome ÷ total outcome

∴ P(1|A) =2/4 or P(1|A) =1/2

b) The first spinner has the total 4 sections. so there are 4 total outcomes.

Favorable outcome = 1

Total number of favorable outcome=3

Probability P(1|B) = favorable outcome ÷ total outcome

∴ P(1|B) =3/4 or P(1|B) =3/4

c)Therefore P(1|A)≠P(1|B)  so the events A and B are dependent.

∴ The interest rate is 10%.

The traditional method is:

SI = (P × R × T)/100

A = P + SI

Where P = main amount, R = rate, T = time, SI = primary interest

Calculations:

Monetary amount 2P

YES = 2P - P

⇒ P = (P × R × 10)/100

8 times the sum of a number and 26 is less than 304.

Answers

Answer:

x < 12

Step-by-step explanation:

So 8 times the sum of a number and 26 is less than 304. To find the number, lets write a equation where the "number" is x.
8 times the sum of a number and 26 can be written as 8 * x+26, however since the sum of x and 26 are being multiplied, we write this as 8(x+26). Since 8 times the sum of a number and 26 is less than 304, we set 8(x+26) to < 304. This gives us our equation:

8(x+26) < 304

Lets start to solve for x by dividing by 8, giving us:

x+26 < 38

Now lets isolate x by subtracting 26 from both sides, which gives us our answer:

x < 12

So x is less than 12.

Answers

The cost equation for Debra is given by 4x + 6y = 94 and for Heather is 5x + 3y = 77.

What are Linear equations in two variables?

Linear equations in two variable have one, none, or infinitely many solutions, with the highest exponent order of 1 in each of the two variables. The standard form of a two-variable linear equation is ax + by + c = 0, where x and y are variables. Solutions can also be written in pairs, for example (x, y). A two-variable linear equation system is represented graphically by two straight lines that can intersect, parallelize, or coincide.

According to the given condition, we have 2 equations:

4x + 6y = 94
5x + 3y = 77

Now, multiply by 2 on both sides of the equation 5x + 3y = 77 to obtain:

10x + 6y = 154

Now, subtracting the equation 10x + 6y = 154 and 4x + 6y = 94.

[10x + 6y = 154] - [ 4x + 6y = 94]

6x + 0y = 60

x = 10

Putting the value of x = 10 in equation 4x + 6y = 94, we get

y = 9

So, the cost of 1 hammer is 10$ and tape is 9$.

The instantaneous velocity at t = 6 is v(6) = 192 ft/s

What are the average and instantaneous velocities of the ball?

The distance traveled as a function of time is s(t) = 16•t² ft.

(a) The distance traveled during the time interval [6, 6.5] is found as follows;

s(6) = 16 × 6² = 576

s(6.5) = 16 × 6.5² = 676

The distance traveled in the interval, [6, 6.5], ∆s(t) = 676 - 576 = 100

The distance traveled during the time interval [6, 6.5] = 100 feet

[5.999, 6]. 191.984

[5.99, 6]. 191.84

Given that at t = 6, as the time interval approaches zero from the right and from the left, the average velocity approaches 192 ft./s, the instantaneous velocity at t = 6, v(6) is 192 ft./s

v(6) = 192 ft./s

Using calculus, differentiation, we have;

v(t) = ds/dt = 2×16 × t = 32•t

v(6) = 32 × 6 = 192

Therefore;

v(6) = 192 ft./s
