What is the value of the median? 8, 12, 14, 20

Answer:

2b² + 2b

Step-by-step explanation:

b + 3b² + b - b²

= 3b² - b² + b + b

= 2b² + 2b

Answer:

[tex] \sf \: {2b}^{2} + 2b [/tex]

Step-by-step explanation:

Given expression,

→ b + 3b² + b - b²

Let's simplify the expression,

→ b + 3b² + b - b²

→ (3b² - b²) + (b + b)

→ (2b²) + (2b)

→ 2b² + 2b

→ 2b(b + 1)

Hence, answer is 2b² + 2b.

when it is 8 inches tall after 9 inches have burned from the candle.

A formula in mathematics is an assertion of a fact, rule, or principle using mathematical symbols. Equations, equalities, identities, inequalities, and asymptotic expressions are a few examples of formulae.

In the theory of logic, the word "formula" is also frequently used to refer to a sentential formula, also known as a propositional formula, or a formula in propositional calculus.

A 17 inch candle is lit and steadily burns until it is burned out.

Let b represent the burned length of the candle (in inches ) and let r represent the remaining length of the candle (in inches) .

Write a formula that expresses r in terms of b r = 17 - b  

Preview b. When 6.8 inches have burned from the candle, the remaining length of the candle is 10.2 inches.

Therefore the point should be on the graph of r in terms of b. c. On the graph below:

Answer:

-6a - 48

The distributive property states that for an expression a(b + c), it can be evaluated to ab + ac.

To distribute, expand the algebraic expression using the aforementioned policy.

[tex]-6(a+8)[/tex]

Multiply a and b together.

[tex]-6\times a=-6a[/tex]

Then, multiply a and c together.

[tex]-6\times8=-48[/tex]

Finally, add the two values together.

[tex]-6a+(-48)=-6a-48[/tex]

[tex]\boxed{\bold{-6a-48}}[/tex]

Hey there!

Distributive Property formula:

a(b + c)

= a(b) + a(c)

= a * b + a * c

= ab + ac

Your equation: -6(a + 8)

Solving:

-6(a + 8)

= -6(a) - 6(8)

= -6 * a - 6 * 8

= -6a - 48

Therefore, your answer should be:

-6a - 48

Step-by-step explanation:

40-10 = 30

30- 12 = 18

18- 8.50 = 9.50

9.50 divided by 1.50 = 6.3

a) 3 - 8 + 2i - (-5i) = -5 + 2i +5i = -5 + 7i

b) 4 - 20i - 2i + 10i² = 4 - 22i + 10([tex]\sqrt{-1}[/tex])² = 4 - 22i + 10(-1) = 4 - 10 -22i

= -6 -22i

c) Multiply both numerator and denominator by i

[tex]\frac{i(-2-4i)}{i^{2} }[/tex] = [tex]\frac{-2i - 4i^{2} }{i^{2} }[/tex] = [tex]\frac{-2i - 4(\sqrt{-1})^{2} }{(\sqrt{-1})^{2}}[/tex] = [tex]\frac{-2i - 4(-1)}{-1}[/tex] = [tex]\frac{-2i+4}{-1}[/tex] = 2i - 4 = -4 + 2i

d) Multiply both numerator and denominator by (3+6i)

[tex]\frac{(3+6i)(-3+2i)}{(3+6i)(3-6i)}[/tex] = [tex]\frac{-9+6i-18i+12i^{2} }{9-36i^{2} }[/tex] = [tex]\frac{-9-12i+12(\sqrt{-1} )^{2} }{9-36(\sqrt{-1} )^{2} }[/tex] = [tex]\frac{-9-12i+12(-1)}{9-36(-1)}[/tex] = [tex]\frac{-9-12-12i}{9+36}[/tex]

The single transformation that transforms ∆RST to ∆R'S'T' is a reflection.

Part A:

For the first figure it is visible that the orientation of the pre-image (∆RST) is similar to that of the image (∆R'S'T').The image is received from the pre-image through moving the pre-image a few units down. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a translation.

Part B:

For the second figure ,it is visible that the orientation of the pre-image (∆RST) is similar to that of the image (∆R'S'T').The image is received from the pre-image through moving the pre-image a few units down and a few units to the right. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a translation.

Part C:

For the third figure it is visible that the orientation of the pre-image (∆RST) isn't similar to that of the image (∆R'S'T').The image is received from the pre-image through rotating the pre-image a few 180 degrees. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a rotation.

Part D:

For the fourth figure it is  visible that the orientation of the pre-image (∆RST) isn't similar to that of the photograph (∆R'S'T').The image is received from the pre-image through reflecting the pre-image.

Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a reflection.

Step-by-step explanation:

Answer:

Step-by-step explanation:

For f (x):

f (x) = (x + 3) ^ 2 - 2

For x = -1

f (-1) = (-1 + 3) ^ 2 - 2

f (-1) = (2) ^ 2 - 2

f (-1) = 4 - 2

f (-1) = 2

For x = 3

f (3) = (3 + 3) ^ 2 - 2

f (3) = (6) ^ 2 - 2

f (3) = 36 - 2

f (3) = 34

AVR = ((34) - (2)) / ((3) - (- 1))

For g (x):

linear graph with and intercept of negative 3 over 2 and x intercept of 3

y = mx + b

b = -3/2

For me we have:

0 = m (3) - 3/2

3m = 3/2

m = 1/2

The function g (x) is:

g (x) = (1/2) x - 3/2

For x = -1

g (-1) = (1/2) (- 1) - 3/2

g (-1) = -1/2 - 3/2

g (-1) = -4/2

g (-1) = -2

For x = 3

g (3) = (1/2) (3) - 3/2

g (3) = 3/2 - 3/2

g (3) = 0

AVR = ((0) - (- 2)) / ((3) - (- 1))

AVR = 1/2

For h (x):

Using the table we have:

AVR = ((62) - (14)) / ((3) - (- 1))

AVR = 12

The difference between the highest recorded temperature on Earth of 134 degrees Fahrenheit and the lowest recorded temperature of -128.6 is equal to 262.6 degrees Fahrenheit.

In mathematics, the difference can be described as the result of the subtraction of one numeral or value to another.

Hence the difference between the highest recorded temperature and the lowest recorded temperature on Earth can be found by the subtraction of the highest and lowest recorded temperatures.

The difference in the two temperatures = highest recorded temperature - lowest recorded temperature

Difference in Farenheit = 134 - ( -128.6)

Difference in Farenheit  = 134 + 128.6

Difference in Farenheit  = 262.6

Hence, the difference between the highest recorded temperature and the lowest recorded temperature is calculated to be 262.6 degrees fahrenheit.

=114

114/9.5

=12

Step-by-step explanation:

1. Needed points is 184 and rewards points was 70

2. So he need extra 114 points for free movie ticket

3. 114 divide by 9.5 which is earn piont for every time he buy ticket

The equation 70 + 9.5x = 184 represents the situation and the number of visits is 12 if Marques has a points card for a movie theater.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Marques has a points card for a movie theater. • He receives 70 rewards points just for signing up

Let x be the number of visits.

The linear equation can be framed as follows:

70 + 9.5x = 184

9.5x = 184 - 70

After solving the above linear equation in one variable:

9.5x = 114

x  = 12

Thus, the equation 70 + 9.5x = 184 represents the situation and the number of visits is 12 if Marques has a points card for a movie theater.

Hence , on solving the given expression , we get values of h(1) = 58/35 ,    h(2) = 86 /35 and  h(-1/2) =26 /35.

We have given an expression h(x)=-4/5x+6/7 .

Putting x = 1 in h(x) , we get

   h(1) = 4/5(1) +6/7

          = 4/5 +6/7

          = 28 + 30 /35

          = 58 /35

Putting x = 2 in h(x) , we get          

   h(2) = 4/5(2) +6/7

          = 8/5 + 6/7

          = 56 + 30 /35

          = 86 /35

Putting x = -1/2 in h(x) , we get      

  h(-1/2) =  4/5(-1/2) +6/7

Here we are given the following-

Principal amount = Rs 4000

Amount received after 2 years = Rs 6000

Time period = 2 years

Let the rate of interest = r%

Then, according to the simple interest formula-

Simple interest = Principal × time period × rate/100

and Simple interest = Final amount - principal amount

Here, simple interest = 6000 - 4000 = Rs 2000

Thus,

2000 = 4000 × 2 × r/100

2000/4000 = 2 × r/100
