Xavier drew a map of an island using a scale in which 2 inches represents 50 feet. The length of the island is 400 feet. What is the length of the island on the map in inches?
Answer:
16 in
Step-by-step explanation:
50 ft x 12 in/ft = 600 in
Scale factor: 2 : 600 = 1 : 300
x = length of island on the map
400 ft = 4800 in
1/300 = x/4800
x = 4800/300 = 16 in

Write the equation for the translation of the graph of ( brackets = absolute value ) y=[2x+7] one unit to the left.
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.
Horizontal translationTo 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
ApplicationHere, 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|

the diagram shows a regular pentagon a) work out the interior angle , b) work out the size of one angle
pls help
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

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.

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.

What is a supplementary angle?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:

You realize that, despite what you expected, the soda actually tastes different depending on which flavor you choose first, second, etc. With this in mind, how many different sodas can you make if repetition is not allowed? Show your work and leave your answer in exponential or factorial form.
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.

find lim x approaches 3
f(x) = x^2 - 2
f(x) = -3x + 15. x> 3
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.

When the sun is at its highest point in the sky, Hong goes to fly a kite in a flat field. He lets out 42.9 feet of string, and the spool of string is 3.4 feet above the ground. The shadow that the kite makes (directly below the kite on the ground) is 16.5 feet away from Hong. How high is the kite off the ground? Round your answer to two decimal places.
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
