Answer:

3(-6 + 2) = -12

Step-by-step explanation:

If a negative is multiplied by another negative we will have a positive, t is -3 and when a negative is in the way the equation is now 3(r - s).

S is - 2 with the negative in the way its now 3(r + 2) ad last r = -6 with no negative in the way the equation is now 3(-6 + 2) which equals 12.

Hope it helps.

Answer:

[tex]y=(\frac{5}{4})^x[/tex]

[tex]y=5^x[/tex]

Step-by-step explanation:

we know that

In a exponential function of the form

[tex]y=a(b^x)[/tex]

where

a is the initial value

b is the base

If the value of b >1 ----> then is a exponential growth

If the value of b <1 ----> then is a exponential decay

Verify each case

case a) we have

[tex]y=(\frac{5}{4})^x[/tex]

[tex]b=\frac{5}{4}[/tex]

b> 1

therefore

The function represent exponential growth

case b) we have

[tex]y=(4)^{-x}[/tex]

[tex]b=\frac{1}{4}[/tex]

b< 1

therefore

The function represent exponential decay

case c) we have

[tex]y=5^x[/tex]

[tex]b=5[/tex]

b> 1

therefore

The function represent exponential growth

case d) we have

[tex]y=(\frac{4}{5})^x[/tex]

[tex]b=\frac{4}{5}[/tex]

b< 1

therefore

The function represent exponential decay

The functions y=(5/4)^x and y=5^x represent exponential growth since the value of the function increases as the exponent (x) increases. This pattern follows the characteristic of exponential growth, where larger values lead to faster rates of increase.

Exponential growth occurs in mathematics when a quantity increases by a fixed percentage or fraction over equal intervals of time. This can be represented by a mathematical function where the variable is an exponent. Looking at the provided options, let's determine which ones represent exponential growth:

Therefore, the functions that represent exponential growth are y=(5/4)^x and y=5^x.

Answer:

Step-by-step explanation:

The fraction that needs to be invested at the higher rate is ...

  (11% - 8%)/(14% -8%) = 3%/6% = 1/2

Half the money should be invested at each of the rates:

  $17,500 for 8% return

  $17,500 for 14% return.

_____

If you let x represent the amount at the higher rate, then the total return is ...

  14%x + 8%(35000 -x) = 11%(35000)

  (14% -8%)x = (11% -8%)(35000) . . . . subtract 8%·35000

  x = (11% -8%)/(14% -8%)×35000 . . . . divide by the coefficient of x

Note that this formula is exactly the one we started with, above.

Answer:

1 Simplify 3/12 to 1/4

Option B:

$2,274.34

Step-by-step explanation:

Given  Nora's house has an assessed value = $76,320

Real estate tax rate = $2.98 per $100

                                 [tex]=\frac{2.98}{100}[/tex]

                                = $0.0298

Tax for assessed value $76,320 = $76,320 × $0.0298

                                                      = $2274.336

                                                      = $2274.34

Hence, tax for Nora's house is $2274.34.

Answer:

7/10 is the larger fraction

Step-by-step explanation:

use cross multiplication

which fraction has the largest number above it.

8 x 7 = 56

5 x 10 = 50

you could also use a common denominator such as 40

5/8 = x/40

25/40

7/10 = x/40

28/40

28>25 so 7/10 is larger

Answer:

48 mph

Step-by-step explanation:

Car B drove for 32 minutes. Car A drove for 17 minutes.

32 - 17 = 15

Car B drove for 15 minutes more than car A.

Car B drove 12 miles more than car A.

That means that in 15 minutes, car B drove 12 miles.

speed = distance/time

15 minutes * (1 hour)/(60 minutes) = 0.25 hour

speed = (12 miles)/(15 minutes)

speed = (12 miles)/(0.25 hour)

speed = 48 miles/hour

Answer: 48 mph

Answer:

with what

Step-by-step explanation:

Answer:

The Correct option is third one { 2, 3 , 5 , 7 , 8 }.

Therefore,

KUL = { 2, 3 , 5 , 7 , 8 }

Step-by-step explanation:

Set:

A set in mathematics is a collection of well defined and distinct objects, also consist of a collection of elements.

Examples given here is

K = { 2, 3 , 5 , 8 }

K is a set consist of number two, three, five, and eight.

Similarly,

L = { 3 , 5 , 7 }

L is a set consist of number three, five, and seven.

Union:

The union of a collection of sets is the set of all elements in the collection.

It is denoted as ' ∪ '

Therefore,

(K∪L) = { 2, 3 , 5 , 7 , 8 }

It is the collection of set K and L both together.

Therefore,

KUL = { 2, 3 , 5 , 7 , 8 }

Answer:

4/3

Step-by-step explanation:

-X + 3/7 = 2X - 25/7

2X + X = 3/7 + 25/7

3X = 28/7

3X = 4

X = 4/3

Answer:

4/3

Step-by-step explanation:

15% off means the dvd is selling for 85% of the original price ( 100% - 15%=85%)

Multiply the original price by 85%

12 x 0.85 = 10.20

The price is $10.20

Final answer:

The probability of a student guessing the correct answer on one multiple choice question with five possible choices is 20%. For specific targets, such as guessing more than 75% correctly, the binomial probability formula would be used.

Explanation:

If a student is taking a multiple choice exam with 100 questions and each question has 5 choices, the probability of guessing correctly on any single question is simply 1 in 5, as there is only one correct answer out of five possibilities. To calculate the probability of an event such as this, where each event is independent and there's an equal chance of each outcome, we use the formula for the probability of a single event, which is P(Event) = Number of successful outcomes / Total number of possible outcomes.

Therefore, the probability of the student guessing the correct answer on one question is P(Correct) = 1/5 or 20%.

If we are dealing with a question about guessing more than a certain percentage correctly, such as more than 75%, we would use the binomial probability formula, which is a bit more complex and depends on the specific question being asked.

Answer:the one at the very bottom

Step-by-step explanation:Because 1-2 is right so then 2-blank would have to be 4 which is the very bottom one.

The correct answer would be option (D) which is a ratio table.

A ratio table is a table that shows the recurring relationship between two values. A set of data points can be used to observe the constant relationship. A set of data with a constant relationship between two values is a comparison of miles traveled to hours traveled. A special type of ratio is the comparison of two different quantities. A rate compares quantities measured in different units.

As per option (D), we have

A     B

1      2

2     4

3     6

The ratio of A and B is :

A:B = 1/2 = 1:2

A:B = 2/4 = 1/2 = 1:2

A:B = 3/6 = 1/2 = 1:2

Hence, we can conclude that this is a ratio table.

The correct answer would be option (D)

Answer:

In the equation y = mx + c if we substitute the value of x as zero we will get a point on the y axis given by y =(m × 0) + c ⇒ y = c. Therefore the point of the line on the y axis is (0, c) and so c is also called the y intercept  of the line.

Step-by-step explanation:

i) from the general equation of line we know that any line can be represented in the form y = mx + c , where m is a constant and is called the slope of the line and c is also a constant and is the y-intercept.

ii) In the equation y = mx + c if we substitute the value of x as zero we will get a point on the y axis given by y =(m × 0) + c ⇒ y = c. Therefore the point of the line on the y axis is (0, c) and so c is also called the y intercept  of the line.

iii) If for example we have the line 3y = 6x + 12 then we first get this equation of the line to match the general form of the equation of the line, that is y = mx + c. Therefore dividing both the left and the right sides of the given equation of the line by 3 we get y = 2x + 4 which matches with the general form of the equation for line and we see that the slope of the given line is m = 2 and the y intercept is given by c = 4.
