Answer:
CD = two square root of 10 end square root
Step-by-step explanation:
To find the length of a segment, use the distance formula. Substitute the order pairs for the endpoints of the segment. CD has the end points (-7, -4) and (-1, -2).
[tex]d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2} \\\\d = \sqrt{(-4--2)^2 + (-7--1)^2} \\\\d = \sqrt{-2^2 + -6^2}\\\\d = \sqrt{4 + 36}\\\\d=\sqrt {40} = 2\sqrt{10}[/tex]
To find the length of segment CD, use the distance formula:
[tex]\[d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.\][/tex] For CD with endpoints (-7, -4) and (-1, -2),
[tex]\[d = \sqrt{40} = 2\sqrt{10}.\][/tex]
To determine the length of a segment, utilize the distance formula by substituting the coordinates of the endpoints. In the case of segment CD, the endpoints are (-7, -4) and (-1, -2).
To determine the length of a segment, the distance formula is applied, denoted as:
[tex]\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \][/tex]
For segment CD with endpoints (-7, -4) and (-1, -2), the distance is computed as follows:
[tex]\[ d = \sqrt{(-1 - (-7))^2 + (-2 - (-4))^2} \][/tex]
This simplifies to:
[tex]\[ d = \sqrt{(6)^2 + (2)^2} \][/tex]
[tex]\[ d = \sqrt{36 + 4} \][/tex]
[tex]\[ d = \sqrt{40} \][/tex]
Hence, the length of segment CD is [tex]\(\sqrt{40}\)[/tex] units. This result can be further expressed as [tex]\(2 \sqrt{10}\)[/tex] by factoring out the square of the largest perfect square, which is 4, from 40. Therefore, the exact length of segment CD is [tex]\(2 \sqrt{10}\)[/tex] units.

Which equations could be used to find the length of a side in a right triangle with legs a and b and hypotenuse of c?
The Pythagorean Theorem says for a right triangle with legs a,b and hypotenuse c,
[tex]c^2 = a^2+b^2[/tex]
Solving for each in turn,
[tex] c= \sqrt{a^2+b^2}[/tex]
[tex]a^2=c^2 - b^2[/tex]
[tex]a = \sqrt{c^2-b^2}[/tex]
[tex]b = \sqrt{c^2-a^2}[/tex]
Looking at our choices, we select the third and fourth.
The pythagorean theorem states that, in every right triangle, the following formula holds:
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs, and c is the hypotenuse.
We can deduce the following expressions for a,b and c:
[tex]a = \sqrt{c^2-b^2},\quad b=\sqrt{c^2-a^2},\quad c=\sqrt{a^2+b^2}[/tex]

Match the functions with their inverse functions.
The answers are:
[tex]f(x)=\frac{5x+3}{2}[/tex]
[tex]f(x)=2x-8[/tex]
[tex]f(x)=7x-2[/tex]
[tex]f(x)=\frac{1}{x+2}[/tex]
Why?To find the inverse function of a function, we need to replace the variable (x for this case) for the function itself (f(x)), where we see "x" we must rewrite with "y" or "f(x) and then, isolate "y" or "f(x). If we have the inverse function and we want to find the function, we need to reverse the process.
Let's find each function of the given inverse functions in order to match each one with its inverse.
First inverse function,
[tex]f^{-1}(x)=\frac{2x-3}{5}[/tex]
Replacing "x" with "f(x)" and "f-1(x)" with "x" we have:
[tex]x=\frac{2f(x)-3}{5}\\\\5x=2f(x)-3\\\\5x+3=2f(x)\\\\f(x)=\frac{5x+3}{2}[/tex]
Therefore, the function that matches with the first inverse function is:
[tex]f(x)=\frac{5x+3}{2}[/tex]
Second inverse function,
[tex]f^{-1}(x)=\frac{x+8}{2}[/tex]
Replacing "x" with "f(x)" and "f-1(x)" with "x" we have:
[tex]x=\frac{f(x)+8}{2}\\\\2x=f(x)+8\\\\2x-8=f(x)\\\\f(x)=2x-8[/tex]
Hence, the function that matches with the second inverse function is:
[tex]f(x)=2x-8[/tex]
Third inverse function,
[tex]f^{-1}(x)=\frac{x+2}{7}[/tex]
Replacing "x" with "f(x)" and "f-1(x)" with "x" we have:
[tex]x=\frac{f(x)+2}{7}\\\\7x=f(x)+2\\\\7x-2=f(x)\\\\f(x)=7x-2[/tex]
So, the function that matches with the third inverse function is:
[tex]f(x)=7x-2[/tex]
Fourth inverse function,
[tex]f^{-1}(x)=\frac{1-2x}{x}[/tex]
Replacing "x" with "f(x)" and "f-1(x)" with "x" we have:
[tex]x=\frac{1-2f(x)}{f(x)}\\\\xf(x)=1-2f(x)\\\\f(x)x+2f(x)=1\\\\f(x)(x+2)=1\\\\f(x)=\frac{1}{x+2}[/tex]
So, the function that matches with the fourth inverse function is:
[tex]f(x)=\frac{1}{x+2}[/tex]

The set of ordered pairs in the mapping below can be described as which of the following?
x----y
0 - 8
3 - 2
6 - -1
(1) a relation only
(2) a function only
(3) both a relation and a function
(4) neither a relation nor a function
Answer:
"(3)"
Step-by-step explanation:
Relation is a mapping between x-values and y-values. Xs are the domain and Ys are the range.
Given x values (0,3,6) and y-values(8, 2, -1), this is a relationship, so it is a relation.
To check whether a relation is a function or not, we simply see if each unique x value is paired with a unique y value.
Is there any y value that is same for x-values? NO! All are different. So this is a function as well!
Answer choice (3) is right.
Answer: (3) both a relation and a function
Step-by-step explanation:
Relation : It is the relation established between two set of values
Function : It is a kind of relation, where only output exist for e ach input.
Generally x values presents input values and y values represents the output values.
The given table :
x - y
0 - 8
3 - 2
6 - 1
Here, each x value is related to a y-value , so its a relation.
Also, there only one unique y-value for each x-values, thus its a function.
Hence, the set of ordered pairs in the mapping below can be described as both a relation and a function.

A parking lot in a shape of a trapezoid has an area of 12,052.1 square meters.the lean the of one base is 82.4 meters and the length of the other base is 108.6 meters.what is the height of the parking lot?
Answer:
126.2 meters
Step-by-step explanation:
A trapezoid's area is found using the formula A = 1/2 (a+b)h where a and b are the two bases. Substitute A = 12,052.1, a = 82.4 and b=108.6. Then solve for h.
A = 0.5(a+b)h
12,052.1 = 0.5(82.4 + 108.6)*h
12,052.1 = 0.5(191)h
12,052.1 = 95.5h
126.2 = h

What is the length of bd?
The length of the bd in the given triangle is 12 cm. This is obtained by applying the Pythagoras theorem.
What is the Pythagoras theorem state?The Pythagoras theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse. I.e., [tex]a^2+b^2=c^2[/tex].
Given data from the diagram:The triangle is perpendicularly divided into two halves looking like right-angled triangles.
The side lengths for the given triangle are bc=13 cm and ac=10 cm
Finding the length of the arm bd:The line segment bd divides the triangle into two right-angled triangles symmetrically.
So, the base ac of the given triangle is divided at the mid-point d.
Thus,
ac = ad + dc
here, d is the mid point, ad = dc
So, ad=dc=5 cm
Now, the triangle forms a right-angled triangle with sides bd, dc, and bc. Where bc is the hypotenuse.
To find the length of bd, applying the Pythagoras theorem
[tex](bc)^2=(bd)^2+(dc)^2[/tex]
⇒ [tex](13)^2 = (bd)^2 + (5)^2[/tex]
⇒ [tex]169 = (bd)^2 +25[/tex]
⇒ [tex](bd)^2 = 169 - 25[/tex]
⇒ [tex](bd)^2 = 144[/tex]
∴ bd = 12 cm
Therefore, the length of the bd is 12 cm.

We can see that each value only shows up one time. Therefore there is no mode. To have a mode, we need to have a value show up more than once, and it must be the most frequent value. For example, the set {1,2,3,3,4} has a mode of 3 since it shows up twice, the most of any value in that set. However we don't have that occur for the data set your teacher gave you.

The function g is defined by g(x)=ax−7, where a is a constant. Find a, if the graph of g passes through the point ( 1/3 ,−2).
Answer:
a = 15
Step-by-step explanation:
The graph of function g(x) is described by g(x)=ax−7, or y = ax−7.
y = g(x)=ax−7 passes through (1/3, -2). We can subst. -2 for y and 1/3 for x to determine the value of the coefficient a:
-2 = g(1/3) = a(1/3) - 7
Solve for a. First, add 7 to both sides: 5 = a(1/3).
Next, multiply both sides by 3: 15 = a, or a = 15.

In 2000 the population of a district was 750,000. With a continuously compounding growth rate of approximately 4%, what will the population be in 2025?
Answer:
2,038,711
Step-by-step explanation:
For a continuously compounding rate r, the growth is modeled by ...
P = P0·e^(rt)
where P0 is the initial population, r is the annual growth rate (compounded continuously) and t is the number of years.
Putting your values into this formula, you have
P = 750000·e^(0.04·25) ≈ 2,038,711
Using the formula for continuous compound growth, the population of the district in 2025 is projected to be approximately 1,226,030.
Explanation:The question is asking about the future population of a district based on continuous compound growth. In this case, the compound interest formula, which includes the principle amount, the rate of growth (interest), and time. The formula often looks as follows: A = P * e^(rt), where A is the amount in the future, P is the principle amount (initial population), r is the rate of growth (interest), and t is the time.
In your case, the calculation would be: A = 750,000 * e^(0.04 * 25). Here, 'e' represents Euler's number (approximately equal to 2.71828), 0.04 is the growth rate, and 25 is the time (years from 2000 to 2025).
Using this formula, we can calculate that the population of the district in 2025 will be approximately 1,226,030 people, assuming a steady growth rate of 4% annually.
