Using exponents, we can find that option 1 and option 8 have same answers. So, (4x²y³) ²/ (2xy) ³ = (8x³y²) ²/ \((2x)^{5} y\)

We frequently read numerical values as terms like hundred, thousand, lakh, crore, and so forth. What figures include more digits than we are able to read? The mass of the Earth, for instance, is 5972190000000000000000000 kg. Simple words cannot be used to read this. Thus, we employ exponents to pronounce certain kinds of numbers.

Here in the question,

Option 1.

(4x²y³) ²/ (2xy) ³

= \(16x^{4} y^{6}\) / 8x³y³

= 2xy³

in option 8,

(8x³y²) ²/ \((2x)^{5} y\)

= \(64x^{6} y^{4}\) / \(32x^{5} y\)

= 2xy³

Therefore, option 1 and option 8 have same answers.

Step-by-step explanation:

Price of mixer = 45.00$

Price of mixer with tax = 47.70

Tax added to the price of mixer = 45 - 47.70

                                                      = 2.70$

Percentage of Tax added to the price of mixer

 =  2.70 = P multiplied by 45

  (divide 2.70 by 45 and 45 by 45 as well)                                  

 = 0.06 = P

  (we have to now convert the decimal to a percentage)

= 0.06 multiplied by 100 = P

   6% = P

2nd: 1/8

3rd: I don't know anything about inchwe study in cm so I don't know the answer

Step-by-step explanation:

we throw a coin. it has 2 probabilities: heads or tails

each probability is 1/2

1st throw 1/2

2nd throw 1/2

3rd throw 1/2

as all these throws are independent from one another, we put × between them. so: 1/2 ×1/2 ×1/2= 1/8

This is an right angle ∆ and the side lengths containing a right angle are 9 and 11.

By Pythagoras theoram,

\( {p}^{2} + {b}^{2} = {h}^{2} \)

where p is the perpendicular, b is the base and h is the hypotenuse.

Plugging the values,

\( {9}^{2} + {11}^{2} = {h}^{2} \)

Then,

\(h = \sqrt{ {9}^{2} + {11}^{2} } \)

\(h = 14.12(approx.)\)

The x of the right angled ∆ = 14.12

Answer:

the top angle is 11 and the angle on the left is 9 so the X will be rounded to the nearest hundreth since it's the biggest angle so 11×9=109 so yea I THINK its 100 since it's rounding

At a temperature of 20°C, the mouse would burn approximately 1,567.44 calories each day.

According to the given model C = 0.37219T + 1,560, where C represents the number of calories an idle mouse burns each day and T represents the temperature of its environment in °C.

To find the most comfortable temperature for an idle mouse, we need to determine the temperature at which the mouse burns the least amount of calories per day.

To find this temperature, we can minimize the equation C = 0.37219T + 1,560. To do so, we take the derivative of C with respect to T and set it equal to zero:

dC/dT = 0.37219 = 0

Solving this equation, we find that the derivative is a constant value, indicating that the function C = 0.37219T + 1,560 is a linear equation with a slope of 0.37219. This means that the mouse burns the least calories at any temperature, as the slope is positive.

Therefore, there is no specific "most comfortable" temperature for an idle mouse in terms of minimizing calorie burn. However, if we consider the range of temperatures mice typically encounter, we can find a temperature where the calorie burn is relatively low.

For example, if we take a temperature of 20°C, we can calculate the calorie burn:

C = 0.37219 * 20 + 1,560

C = 7.4438 + 1,560

C ≈ 1,567.4438 calories per day

Therefore, at a temperature of 20°C, the mouse would burn approximately 1,567.44 calories each day.

Option A is the correct answer. The probability of the nearest hundredth of the pointer landing on a non-shaded area is 0.66.

An angle of a circle is an angle that is formed between the radii, chords, or tangents of a circle. It contains a total of 360° degrees all the way around the center.

To know the Probability of the non-shaded area first we have to add the shaded area.

The sum of the shaded angles 48°+45°+122°+52° =145°.

As we know that the total angle of a  circle=360°.

Now divide the sum of the shaded angles by the total angle of the circle.

Let \(x\) be the number of bags of chips Bonnie bought.

Then, the number of cans of pop she bought is \(x + 10\).

The total cost is \(\$17.50\), so we can write an equation:

\(\qquad\qquad 0.5x + 1(x + 10) = 17.50\)

Simplifying and solving for x:

\(\qquad\qquad\begin{gathered}0.5x + x + 10 = 17.50 \\ 1.5x + 10 = 17.50 \\ 1.5x = 7.50 \\ \fbox{x = 5}\end{gathered}\)

SOLUTION: 5 bags of chips and 15 pops

Solving by substitution, choose your variables. In this case, let “c” represent the number of chips, and “p” the number of pop

Make your equations:

1.00p + 0.50c = 17.50

c + 10 = p

In the first equation, substitute “p” for the second equation:

1.00(c + 10) + 0.50c = 17.50

Distribute 1.00 to everything within the brackets:

1.00c + 10.00 + 0.50c = 17.50

Solve for “c”.

1.00c + 0.50c + 10.00 = 17.50

1.50c = 17.50 - 10.00

1.50c = 7.50

c = 5

Now, since we know that “p” is 10 more then “c”, we can substitute “c” for 5 in the second equation:

5 + 10 = p

15 = p

t² -4t -4t + 16 = 0

The two numbers are 4 and -4.

Step 2: Rewrite the equation in the form (t + 4)(t - 4).

t² - 8t + 16 = (t + 4)(t - 4)

Step 3: Factor the equation to get (t + 4)².

The simplified equation is (π2 / 2) * ∫[0, ∞] (x(2x-1) * e(-x) / (Γ(x) * Γ(1 - x)) DX

a. To prove B(x+1, y) = x * B(x, y), proceed as follows.

Start with B(x+1, y) = [(x+1)! * y!] / ((x+y+2)!) (using the definition of B(x, y)).

Rewrite 1 / (x+1) to (x+y+2 - (y+1)) / (x+y+2) .

Using the formula above, express B(x+1, y) as (x+y+2) / (x+y+2) * [(x+1)! to rewrite. * y!] / ((x+y+2)!) - (y+1) / (x+y+2) * [(x+1)! * y!] / ((x+y+2) !).

Simplify the formula to (x+y+2) / (x+y+2) * B(x, y) - (y+1) / (x+y+2) * B(x, y) increase.

Simplify further to B(x, y) - (y+1) / (x+y+2) * B(x, y).

Note that B(x, y) can be expressed as (x / (x+y+1)) * B(x, y) .

Substitute this formula in the previous step to get,

x * B(x, y) - (y+1) / (x+y+2) * x * B(x, y).

x * B(x, y) - (y+1) / (x+y+2) * x * B(x, y)

= x * B(x, y)

You have now proved B(x+1, y) = x * B(x, y).

b. We wish to prove the identity Γ(2x) = ((2sin(πx))) * Γ(x) * Γ(x + 1/2).

Integrate ∫[0, ∞] (x(2x-1) * Start with dx.

Evaluating this integral using the permutation u = du is obtained.

Simplify the integral to (1/2) * Γ(x + 1/2).

Express sin(πx) as π / (Γ(x) * Γ(1 - x)).

Let the original integral be π * (2(2x-1) / π) * ∫[0, ∞] (x(2x-1) * e(-x) * (1/sin( πx) Rewrite.)) DX.

Substituting the equations,

The integral, π * (2(2x-1) / π) * ∫[0, ∞] (x(2x-1) *

Answer:

  g(x) = 3 + tan(πx/4)

Step-by-step explanation:

A tangent function has a period of π. In order to make it have a period of 4, it needs to be stretched horizontally by a factor of 4/π. A function is stretched horizontally by a factor of k by replacing x with x/k.

In order for the function to be shifted vertically up by 3 units, 3 must be added to the function value. That is, the transformed function becomes ...

  g(x) = tan(x/(4/π)) +3

  g(x) = tan(πx/4) +3

Answer:

  25 yards long, 5 yards wide

Step-by-step explanation:

The given parameters can be used with the area and perimeter formulas for a rectangle to form an equation that can be solved for the dimensions.

The length and width can be represented by x and y. The formulas for area and perimeter give two equations relating these two variables:

  A = LW   ⇒   125 = xy

  P = 2(L+W)   ⇒ 60 = 2(x +y)

Using the second equation to write an expression for y, we have ...

  y = 30 -x

Substituting into the first equation gives ...

  125 = x(30 -x)

This suggests we can find x by looking for factors of 125 that total 30.

  125 = 1(125) = 5(25)

Factor totals are 126 and 30. This means we have ...

  x = 5, y = 30-5 = 25

or

  x = 25, y = 30 -25 = 5

The rectangle dimensions are 5 yards by 25 yards.

The equation for the line through the point (-7,-4) and parallel to the line y = 8x - 4 in point-slope form is y = 8x + 52

The first equation is given as

y = 8x - 4

The slope of the above equation is

m = 8

Parallel lines have equal slope

So, the slope of the other line is

m = 8

The equation is then calculated as

y = m(x - x1) + y1

Where

m = 8

(x1, y1) = (-7, -4)

So, we have

y = 8(x + 7) - 4

Expand

y = 8x + 56 - 4

Evaluate the difference

y = 8x + 52

Hence, the equation for the line through the point (-7,-4) and parallel to the line y = 8x - 4 in point-slope form is y = 8x + 52
