Answer:

The value of the stock can be found by: x × 1.26.

Step-by-step explanation:

The value of the stock in year one can be found by multiplying x by 1.4. This will represent a 40% increase in value. The following year, the stock decreases in value by 10%; this is represented by multiplication by 0.9. For example, if the value of the stock was $5:

5 × 1.4 = 7                    (A 40% increase in value)

(5 × 1.4) * 0.90 = 6.3   (A further 10% decrease in value)

Rather than writing out the long version, we can simplfify by multiplying 1.4 by 0.9 to get 1.26 .We can also replace 5 with x to get a more general equation.

Answer:

y = 2x² - 24x + 76

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here a = 2 and (h, k ) = (6, 4 ) , then

y = 2(x - 6)² + 4 ← in vertex form

expand factor using FOIL

y = 2(x² - 12x + 36) + 4 ← distribute parenthesis by 2

y = 2x² - 24x + 72 + 4

y = 2x² - 24x + 76 ← in standard form

Step-by-step explanation:

The time Akeem runs on days must be 9.3 minutes or less than 9.3 minutes if the mean running time for 7 days must be 9 minutes or less.

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have:

Akeem will record the time it takes him to run 1 mile each day for 7 days. In order to meet his fitness challenge, his mean running time for 7 days must be 9 minutes or less.

Here we are assuming that it is required to find the time Akeem runs on the 7th day.

Let's suppose Akeem runs x minutes on the 7th day.

Mean running time ≤ 9

The mean:

[tex]\dfrac{(9.4+9.0+9.1+8.9+8.5+8.8+x)}{7} \leq 9[/tex]

[tex]\dfrac{(53.7+x)}{7} \leq 9[/tex]

53.7 + x ≤ 63

x ≤ 9.3 minutes

Thus, the time Akeem runs on days must be 9.3 minutes or less than 9.3 minutes if the mean running time for 7 days must be 9 minutes or less.

An equation is formed of two equal expressions. Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A.) Let the amount of time spent on soccer be represented by y, while the amount of time spent on softball is represented by x. Therefore, we can write,

x+y=18

y=2x+1.5

Hence, the system of equations to model the situation is x+y=18 and y=2x+1.5.

B.) Substitute the value of y from the second equation in the first equation, therefore,

x+y=18

x+2x+1.5=18

3x = 16.5

x = 5.5 hours

Substitute the value of x in the second equation, we will get,

y=2x+1.5

y=2(5.5)+1.5

y=11+1.5

y=12.5 hours

Hence, Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.

Answer:

2/13

Step-by-step explanation:

4/14 × 7/13  when i simplify it becomes 2/13!!!

The probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is 2/13.

Probability helps us to know the chances of an event occurring. The sum of all the probabilities of an event is always equal to 1. The formula for probability is given as,

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The probability of getting a blue marble at the first try is,

Probability(Blue) = Number of blue marbles / Total number of marbles

                            = 4 / 14

The probability of getting a red marble at the second try is,

Probability(Red) = Number of Red marbles / Total number of marbles

                            = 7 / 13

The probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is,

Probability = Probability(Blue) × Probability(Red)

                   = (4/14) × (7/13)

                   = 2/13

Hence, the probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is 2/13.

Answer:

General form of a linear equation:  [tex]y=mx+b[/tex]

(where m is the slope and b is the y-intercept)

A linear equation has a constant rate of change which is represented by the slope (m).  It is the rate at which one quantity is changing with respect to another quantity.

Part (a)

Given equation:  [tex]y=-9x+55000[/tex]

where:

The rate of change (slope) is -9 and represents that for every 1 mile driven, the value of the car decreases by $9.

The initial value is the y-intercept (b) as this is the value when x = 0.

Therefore, the initial value of car is $55,000.

Part (b)

To find the number of miles at which the car be valued at $35,002, set the equation to $35,002 and solve for x:

[tex]\implies -9x+55000=35002[/tex]

[tex]\implies -9x=35002-55000[/tex]

[tex]\implies -9x=-19998[/tex]

[tex]\implies x=\dfrac{-19998}{-9}[/tex]

[tex]\implies x=2222[/tex]

Therefore, the car will be valued at $35,002 after 2,222 miles.

Given equation:  [tex]y=0.39x+2.55[/tex]

where:

The rate of change (slope) is 0.39 and represents that for every increase of 1 oz of weight in carrots, the price of the carrots increases by $0.39

The initial value is the y-intercept (b) as this is the value when x = 0.

Therefore, the initial cost of the carrots is $2.55.

Part (b)

To find the weight of carrots you can buy for $6.06, set the equation to $6.06 and solve for x:

[tex]\implies 0.39x+2.55=6.06[/tex]

[tex]\implies 0.39x=6.06-2.55[/tex]

[tex]\implies 0.39x=3.51[/tex]

[tex]\implies x=\dfrac{3.51}{0.39}[/tex]

[tex]\implies x=9[/tex]

Therefore, you can buy 9 oz of carrots for $6.06

Part (c)

To find out how much it costs to buy 21 oz of carrots, substitute x = 21 into the equation and solve for y:

[tex]\implies y=0.39(21)+2.55[/tex]

[tex]\implies y=10.74[/tex]

Therefore, it costs $10.74 to buy 21 oz of carrots.

The volume of cylinder is 2352π in³ while the volume of cone is 784π in³. The volume of the cylinder is three times the volume of the cone

An equation is an expression that shows the relationship between two or more numbers and variables.

A cylinder has radius 14 inches and height 12 inches. A cone has the same radius and height.

Volume of cylinder = π * radius² * height = π * 14² * 12 = 2352π in³

Volume of cone = (1/3) * π * radius² * height = (1/3) * π * 14² * 12 = 784π in³

The volume of the cylinder is three times the volume of the cone.

The credit card industry and cigarette industry are very similar in terms of negative influence on personal finances.

A credit card is a sort of payment card that uses a line of credit rather than the account holder's cash deposits to make purchases.

Tobacco use can have a negative impact on personal finances due to the sheer high price of tobacco products, wasted pay owing to sickness absence, plus hospitalization rates due to the higher risk of illness associated with smoking use.

If you let that debt grow, you may find that the amount of interest you owe equals or even exceeds your original principal, forcing you to spend a lot just to pay it off.

Thus, the credit card industry and cigarette industry are very similar in terms of negative influence on personal finances.
