Ignore the fact that this is answered, im not sure if the answer is right. What is the right answer?

Answer: (I am not a maths moderator)

x=4

Step-by-step explanation:

Multiply the exponents

(2x-4)^12=(4^2)^6 (exponents multiply so)

(2x-4)^12=4^12

4^12 = 16777216

(2x-4)^12= 16777216

Take the 1/12 exponent for both sides

that will remove the ^12 exponent from the left side and will take the 12th root for the right.

2x-4=4

add 4 to both sides

2x=8

divide both sides by 2

x=4

Answer:

x=4

Step-by-step explanation:

[tex](2x-4)^{12}[/tex]  =[tex]16^{6}[/tex]

2x-4=[tex]\sqrt[12]{16^{6} }[/tex]  =4

x=4

The length is 5

Step-by-step explanation:

Let the length be x

Width = ( X - 2)

Area = 15

area = length * width

15 = x(x -2)

15 = x² - 2x

x² - 2x - 15 = 0

(x² + 3x) - (5x - 15) = 0

x(x + 3) - 5(x + 15) = 0

x - 5 = 0 or x + 15 = 0

x =5 or x = -15

x = 5

Answer:

Minimum: [tex](\frac{\sqrt{5} }{5},-2+\frac{4\sqrt{5} }{5})[/tex]

Maximum: [tex](-\frac{\sqrt{5} }{5} ,-2-\frac{4\sqrt{5} }{5} )[/tex]

Answer:8

Step-by-step explanation:

We can expect 8 of the next 16 people to have black hair, based on the given information.

It is a branch of mathematics that deals with the occurrence of a random event.

Since 2 out of the total number of people who have already taken their seats at the seminar have black hair

we can assume that the probability of a person having black hair is 2 out of the total number of people who have taken their seats.

The probability of a person having black hair can be expressed as:

P(black hair) = 2/(2+2) = 1/2

This means that out of the total number of people who have already taken their seats, half of them have black hair.

If we assume that the next 16 people to take their seats are chosen randomly and independently from the population,

we can use the expected value formula to calculate the number of people with black hair we would expect among those 16 people:

Expected value = total number of people x probability of having black hair

Expected value = 16 x (1/2)

Expected value = 8

Therefore, we can expect 8 of the next 16 people to have black hair, based on the given information.

The formula for this would be [tex]2/3 \times4[/tex]

Since we need to multiply the fraction against the amount of batches, to get the final result of cups of flours. (It only makes sense!)

8/3 is the correct answer

2 2/3 is the mixed fraction

Answer as an improper fraction:  8/3

This converts to the mixed number 2 & 2/3

So he'll need 2 whole cups plus another 2/3 of a cup.

===========================================================

Explanation:

1 batch uses 2/3 of a cup

4 batches uses 4*(2/3) = (4/1)*(2/3) = (4*2)/(1*3) = 8/3 of a cup

Simply multiply 2/3 by 4 to get 8/3.

-----------

If you need to convert to a mixed number, then you could follow these steps

8/3 = (6+2)/3

8/3 = 6/3 + 2/3

8/3 = 2 + 2/3

8/3 = 2 & 2/3

Or you could note that 8/3 = 2.667 approximately. The decimal portion 0.667 converts to the fraction 2/3.

1 5/6 + 1 1/3 = 3 1/6

3 1/6 * 60 = 190

Answer:

15. a because b is being squared by a variable meaning it is exponential and goes forever, but the answer choice B is set only to 3 squared, so a is the answer.

The value of x is 1 if the angle CBA is 43x, and after applying the tangent-chord angle theorem option (B) is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have a circle shown in the picture.

From the tangent-chord angle theorem:

Angle CBA = (1/2)[360 - (272x+2)]

Angle CBA = (1/2)[360 - 272x - 2]

Angle CBA = (1/2)[358 - 272x ]

43x = 179 - 136x

179x = 179

x = 1

Thus, the value of x is 1 if the angle CBA is 43x, and after applying the tangent-chord angle theorem option (B) is correct.

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the 8 expressions are not given.

The general explanation is as follows

As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.

Then you categorize each result, depending on if it equals [tex]5^{10}[/tex] or not

Take for instance:

[tex]5^5 * 5^5[/tex]

Using law of indices:

[tex]5^5 * 5^5 = 5^{5+5[/tex]

[tex]5^5 * 5^5 = 5^{10[/tex] ---- equivalent

[tex]\frac{5^5 + 5^5}{2 * 5^{-5}}[/tex]

Factorize the numerator

[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1 + 1)}{2 * 5^{-5}}[/tex]

[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}[/tex]

Cancel out 2

[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}[/tex]

Apply law of indices

[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}[/tex]

[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}[/tex]

[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10[/tex] ---equivalent

[tex]125 * 78125[/tex]

Express as exponent

[tex]125 * 78125 = 5^3 * 5^7[/tex]

Apply law of indices

[tex]125 * 78125 = 5^{3+7[/tex]

[tex]125 * 78125 = 5^{10[/tex] ---- equivalent

[tex]5^3 + 5^7[/tex]

Solve exponents

[tex]5^3 + 5^7 = 125 + 78125[/tex]

[tex]5^3 + 5^7 = 78250[/tex] ---- not equivalent

Answer:

[tex]y=3x-7[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the points given are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Points (3,2) and (6,11)

[tex]=\frac{11-2}{6-3}\\=\frac{9}{3}\\= 3[/tex]

Therefore, the slope of the line is 3. Plug this into [tex]y=mx+b[/tex]:

[tex]y=3x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=3x+b[/tex]

Plug in one of the given points and solve for b

[tex]2=3(3)+b\\2=9+b[/tex]

Subtract 9 from both sides

[tex]2-9=9+b-9\\-7=b[/tex]

Therefore, the y-intercept of the line is -7. Plug this back into [tex]y=3x+b[/tex]:

[tex]y=3x-7[/tex]

Decay rate of 2%

Step-by-step explanation:

Since there is no information about the units for time, merely stating that the decay rate is 2% will suffice. The decay rate for when r < 1 is found by finding 1-r, so the rate of decay is .02, or 2%.
