Step-by-step explanation:

What is the Formula for Calculating the Square Root of a Number? The square root of any number can be expressed using the formula: √y = y½. In other words, if a number has 1/2 as its exponent, it means we need to find the square root of the number.

In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number.

The square root of a number "a" is denoted by the symbol "√a" or "a^(1/2)." For example, the square root of 9 is 3 because 3 * 3 = 9.

Measure of one exterior angle = 30 degree

Measure of one interior angle = 150 degree

In the given regular pentagon

Number of terms = 12

We know that,

Sum of all exterior angles = 360 degree

To find one exterior angle,

Divide the complete angle by number of terms

Therefore,

One exterior angle = 360/12  =  30 degree

Since,

Sum of all interior angles = 180 degree

And To find one interior angle,

subtract the interior  angle by one exterior angle

Therefore,

One exterior angle = 180 - 30  =  150 degree

The number of different sodas that can be made is given by "n!" or factorial form.

If the soda tastes different depending on the order in which the flavors are chosen, we can calculate the number of different sodas that can be made without repetition using the concept of permutations.

Let's assume we have "n" different flavors of soda available. To calculate the number of different sodas we can make, we need to find the number of permutations of "n" flavors taken "r" at a time, where "r" is the number of flavors we want to choose for each soda.

The formula to calculate permutations is given by:

P(n, r) = n! / (n - r)!

Here, "n!" represents the factorial of "n," which is the product of all positive integers less than or equal to "n."

In this case, if repetition is not allowed, each soda can have only one flavor. Therefore, we have "r = 1" for each soda.

Applying the formula, we have:

P(n, 1) = n! / (n - 1)!

= n! / (n - 1)

= n

Hence, the number of different sodas that can be made without repetition is "n."

Therefore, the number of different sodas that can be made is given by "n!" or factorial form.

In the figure, AB is a diameter, and AB⊥CD, If m AC = 54°, BD is 36°. Option A

In a circle, a diameter divides it into two equal parts and forms a straight line that measures 180°.

Given that AB is a diameter = 180°.

AB is perpendicular to CD, therefore m∠AC + m∠BD = 90°.

Substituting m∠AC =54°, we get m∠BD + 54°  = 90°.

Solving for m∠BD, we get 90° - 54° = 36°.

There BD is 36°.

Step-by-step explanation:

She walks the entire CIRCUMFERENCE of the circle

circumference = pi X diameter

                       = pi X 14 ft = 43.98 ft  = ~ 44 ft (rounded)

The height of the kite off the ground is approximately 17.87 feet rounded to two decimal places.

To solve the problem can use similar triangles.

Let's draw a diagram:

     A

      |\

      | \

   h |   \   x

      |      \

      |____\

       d   B

Point A represents the kite, point B represents the tip of the kite's shadow on the ground and point D represents the point directly below the spool of string on the ground.

The height of the kite represented by h.

The length of the string is 42.9 feet so the distance from point A to point D is also 42.9 feet.

The distance from point B to point D is 16.5 feet.

These two lengths to find the length of segment AB:

AB/AD = BD/AD

AB/42.9 = 16.5/42.9

AB = 16.5

So AB is 16.5 feet.

Now we can use the similar triangles to find h.

We have:

h/x = AB/AD

h/x = 16.5/42.9

h = x × 16.5/42.9

We need to find x.

The spool of string is 3.4 feet above the ground and we know that the kite is directly above the spool when it is at its highest point in the sky.

So the height of the kite above the ground is the same as the height of the spool above the ground plus the length of string that has been let out:

x = 3.4 + 42.9

= 46.3

Now we can substitute this value of x into the previous equation to find h:

h = 46.3 × 16.5/42.9

= 17.87

Answer:

  y = |2x +9|

Step-by-step explanation:

You want the equation that will translate the graph of y = |2x +7| one unit to the left.

To translate the graph of f(x) by h units to the right, you want to replace x with x-h:

  f(x-h) . . . . translates f(x) by h units to the right

Here, we want a translation by 1 unit to the left, which is -1 unit to the right. This means we want to replace x in the function by (x -(-1)) = (x +1). Doing that gives ...

  y = |2(x +1) +7)| = |2x +2 +7|

  y = |2x +9|

After completing the square for the equation [tex]\(x^2 + 12x - 85\)[/tex], we find that the possible result is [tex]\((x + 6)^2 = 49\)[/tex].

To complete the square for the equation [tex]\(x^2 + 12x - 85\)[/tex], we follow these steps:

1. Take half of the coefficient of the [tex]x[/tex] term, which is [tex]\(12/2 = 6\)[/tex].

2. Square this result, [tex]\(6^2 = 36\)[/tex].

3. Add this value, 36, to both sides of the equation to maintain balance:

[tex]\[x^2 + 12x + 36 - 85 = 36 - 85.\][/tex]

4. Simplify both sides of the equation by combining like terms:

  [tex]\[(x + 6)^2 - 49 = 0.\][/tex]

5. Rearrange the equation to isolate the perfect square term:

 [tex]\[(x + 6)^2 = 49.\][/tex]

From this process, we can conclude that the equation [tex]\((x + 6)^2 = 49\)[/tex] could be the result of completing the square for the given equation [tex]\(x^2 + 12x - 85\)[/tex]. This equation represents a perfect square trinomial with a perfect square term, and it allows us to solve for the value of [tex]x[/tex] by taking the square root of both sides.

It's important to note that completing the square allows us to rewrite quadratic equations in a form that reveals key properties and facilitates solving for unknowns.

b) She incorrectly changed the place value of 0.02 in the subtraction operation.

c) Based on the correct subtraction operation and place value in step one, Fatima has 0.395 kilograms of rose petals left.

The place value shows the position of a digit in a number.

The right place values are essential for correct mathematical operations.

The quantity of rose petals that Fatima bought initially = 0.454 kilograms

The quantity of rose petals used for making rose water = 0.02 kilograms

The remaining quantity of rose petals = 0.434 (0.454 - 0.02)

The additional quantity of rose petals Fatima bought = 0.056

The quantity of rose petals used for making the second rose water = 0.095

In the graph, the closing price per share of stock for a company is represented each day for 28 days. After analyzing the graph, the variable which is represented on the horizontal axis is days and the stock price generally increasing in the first week. The closing price of the stock decrease for at least 3 days in a row during day 7 to day 10.

The graph represents the closing price per share of stock for a company each day for 28 days. That's the number of days in the first week. So days is the variable represented in the horizontal axis.

In the first seven days, the graph is basically going up, and then it gets slower and then it's going up. So it's increasing the entire time. Not at the same rate, but it's increasing.

From day 7 to day 10, the closing price of the stock was decreasing three days in a row.

Step-by-step explanation:

You multiply the length value by 1,760.

3520 yards is equivalent to 2 miles.

An equation that can be used to find the value of x include the following: 110° + 7x = 180°.

In Mathematics and Geometry, a supplementary angle simply refers to two (2) angles or arc whose sum is equal to 180 degrees.

Additionally, the sum of all of the angles on a straight line is always equal to 180 degrees. In this scenario, we can reasonably infer and logically deduce that the sum of the given angles are supplementary angles:

110 + 7x = 180°

7x = 180° - 110°

7x = 70°

x = 70°/7

x = 10°

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

The value of the limit of the function f(x) = x² - 2 is 7.

The value of the limit of the function f(x) = -3x + 15 is -6.

We have,

To evaluate the limit as x approaches 3, we need to find the limit of function f(x) as x approaches 3 from both sides of 3.

First, let's evaluate the limit from the left side of 3:

lim x → 3⁻ f(x) = lim x → 3⁻ (x^2 - 2)

Substituting x = 3 - h (where h approaches zero) gives:

lim h → 0⁺ [(3 - h)^2 - 2]

= lim h → 0⁺ [9 - 6h + h^2 - 2]

= lim h → 0⁺ [h^2 - 6h + 7]

= 7

(since the limit of a quadratic function as h approaches zero is the constant term)

Next, let's evaluate the limit from the right side of 3:

lim x → 3⁺ f(x)

= lim x → 3⁺ (-3x + 15)

= -6

Since the limit from the left side is not equal to the limit from the right side, the limit of f(x) as x approaches 3 does not exist.

Thus,

The value of the limit of the function f(x) = x² - 2 is 7.

The value of the limit of the function f(x) = -3x + 15 is -6.
