Answer:
The median is 5cm.
Step-by-step explanation:
Median is one of the 3 famous measures of central tendency.
The others are: mean & mode.
A median is the middle figure in an array of figures which are lined up from lowest value to highest value.
Here, the variable we're working with is Amount of rainfall in Vietnam cities (in centimeters).
The data shows 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 0cm, 1cm, 2cm, 3cm
We start by arranging them in order of value; from lowest to highest:
0cm, 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm
There are 11 values in total.
Since 11 is an odd number, it is easy to find the median in this set of values.
Five values to the left and five values to the right; the median is 5cm!
Every year Samatha receives a $50 dollar bonus. She also receives $5 For every year that she has been working. Emily receives a $40 bonus She also receives $10 for every year that she has been working. In 2018 , Samatha worked for 6 years and Emily worked for 2 years. In what year will they both receive the same amount of money?
Answer:
Year 2022
Step-by-step explanation:
Let number of years = x
Samantha :
Bonus + yearly earning
50 + 5x
Emily :
40 + 10x
Curent earning in 2018:
Years worked by Samantha = 6
50 + 5(6) = 50 + 30 = 80
Years worked by Emily = 2
40 + 10(2) = 60
Year when they'll both receive same amount :
80 + 5x = 60 + 10x
5x - 10x = 60 - 80
-5x = - 20
x = 20/5
x = 4 ; x = 4 years
2018 + 4 = 2022
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the
ranslation?
O(x, y) = (x + 5, y-3)
O (X,Y) - (x + 5, y + 3)
O(x, y) = (x-3, y + 5)
(x, y) = (x + 3, y + 5)
Answer:
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left.
3) O(x,y)=(x-3,y+5)
The rule that describes the translation is (x, y) -> (x - 3, y + 5), the correct option is C.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units:
y=f(x+c) (same output, but c units earlier)
Right shift by c units:
y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y =[tex]k \times f(x)[/tex]
Horizontal stretch by a factor k: y = [tex]f\left(\dfrac{x}{k}\right)[/tex]
We are given that;
5 units up and 3 units to the left
Now,
In this case, the rectangle is translated 5 units up and 3 units to the left. This means that the vertical shift is 5 and the horizontal shift is -3.
After transformation x=x - 3
Y=y + 5
Therefore, the transforming function will be (x, y) -> (x - 3, y + 5).

A system of two equations is shown.
2 + 2y = 6
2x - 3y = 26
What is the solution of the system?
0 (-2,3)
(1, -2)
O (-2.4)
(10.-2)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the system of equations
2 + 2y = 6
2x - 3y = 26
Let us solve the system of equations
[tex]\begin{bmatrix}2+2y=6\\ 2x-3y=26\end{bmatrix}[/tex]
Rearrange equations
[tex]\begin{bmatrix}-3y+2x=26\\ 2y=4\end{bmatrix}[/tex]
Multiply -3y+2x=26 by 2: -6y+4x=52
Multiply 2y = 4 by 3: 6y = 12
[tex]\begin{bmatrix}-6y+4x=52\\ 6y=12\end{bmatrix}[/tex]
adding the equations
[tex]6y=12[/tex]
[tex]+[/tex]
[tex]\underline{-6y+4x=52}[/tex]
[tex]4x=64[/tex]
Solve 4x = 64 for x
[tex]4x = 64[/tex]
divide both sides by 4
[tex]\frac{4x}{4}=\frac{64}{4}[/tex]
Simplify
[tex]x = 16[/tex]
For -6y+4x = 52 plug in x = 16
[tex]-6y+4\cdot \:16=52[/tex]
Multiply the numbers: 4 · 16 = 64
[tex]-6y+64=52[/tex]
Subtract 64 from both sides
[tex]-6y+64-64=52-64[/tex]
Simplify
[tex]-6y=-12[/tex]
Divide both sides by -6
[tex]\frac{-6y}{-6}=\frac{-12}{-6}[/tex]
[tex]y=2[/tex]
Therefore, the solution to the system of equations be:
[tex]y=2,\:x=16[/tex]
Thus,
(x, y) = (16, 2)

DETERMINA EL VOLUMEN DE UN PRISMA PENTAGONAL QUE TIENE LAS SIGUIENTES MEDIDAS: LADO 6.1 CM, APOTEMA 4.5, ALTURA 12.5CM DEL PRISMA
Answer:
837.23 cm³
Step-by-step explanation:
La fórmula para el volumen de un prisma pentagonal se da como:
1/2 (5 s × a) × h
Dónde:
s = longitud lateral
a = Apotema
h = altura
De la pregunta anterior:
s = largo de lado = 6.1 cm
a = Apotema = 4.5 cm
h = Altura = 12.5 cm
Por lo tanto:
El volumen del prisma pentagonal =
1/2 (5 × 6.1 × 4.5) × 12.5
= 1/2 × 137.25 × 12.5
= 837.225 cm³
Aproximadamente = 837.23 cm³

Kiara invested $3,500 into two accounts. One account paid 5% interest and the other paid 7.5% interest. She earned 6%
interest on the total investment. How much money did she put in each account?
Answer:
A=$2100
B=$1400
Step-by-step explanation:
3500*1.06=3710
a+b=3500
1.05a+1.075b=3710
1.05a+1.05b=3675
1.05a+1.075b=3710
Subtract 1.05a+1.05b=3675 from 1.05a+1.075b=3710
0.025b=35
b=1400
a=3500-1400=2100
Double check: (2100*1.05)+(1400*1.075)=3710
3500*1.06=3710
The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
0.05a + 0.075b = (0.06 x $3500)
0.05a + 0.075b = $210 ----- equation 1
a + b = $3,500 -------- equation 2
Where:
a is the amount invested in the account that paid a 5% interest.
b is the amount invested in the account that paid a 7.5% interest.
The amount invested in the account that pays a 7.5% interest.
In order to determine this value, multiply equation 2 by 0.05
0.05a + 0.05b = 175 ------- equation 3
0.025b = 35
b = $1400
The amount invested in the account that pays a 5% interest.
a + $1400 = $3500
a = $3500 - 1400
a = $2100
Therefore, The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.

Determine if each relation is a relation or not
A function is represented as: [tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3)...(x_n,y_n)\}[/tex]
Where
[tex]x = domain[/tex] and [tex]y = range[/tex]
For a relation to be a function:
No x value (in other words, the domain) must be repeated
[tex](a):\ y = \frac{x + 3}{7}[/tex]
The above relation is a function. This is so because every unique value of x have a unique value of y.
In other words:
No two domains exist for a range
Conclusively, it is a one-to-one function
[tex](b):[/tex]
[tex]\begin{array}{ccccc}x & {-2} & {-2} & {1} & {3} \ \\ y & {-5} & {-1} & {3} & {7} \ \ \end{array}[/tex]
In the above table, we have:
[tex](x_1,y_1) = (-2,5)[/tex] and [tex](x_2,y_2) = (-2,-1)[/tex]
The domain (-2) points to range (5 and -1).
Based on the condition that no two domain should point to the same range, we can conclude that this is not a function.
[tex](c):[/tex]
[tex]\begin{array}{ccccc}x & {-3} & {-1} & {1} & {3} \ \\ y & {-4} & {-4} & {2} & {2} \ \ \end{array}[/tex]
In the above table, we have the domain to be:
[tex]x = \{-3,-1,1,3\}[/tex]
We can see that no x value is repeated.
Hence, this is a function.

Find the zeroes of the function and write in a+bi form. -(x+1)^2-4=0
Answer:
x = 2 + √-16 [ (-2)⁻¹]
See steps below.
Step-by-step explanation:
Finding the zeroes of a function simply means solving for the unknown variable (in this case "x") when the function is equated to zero.
The function here is [tex]f(x) = -(x + 1)^{2} - 4 = 0[/tex]
Start by opening the bracket. Ignore the minus sign. It will be reintroduced at the end of this step.
(x + 1)(x + 1) = x² + x + x + 1 = x² + 2x + 1
Reintroduce the minus sign. Don't forget to put the result above back in a bracket.
- (x² + 2x + 1) = -x² -2x -1
Place the expression back in the equation and solve. Make sure to put it back in the position where it was.
-x² - 2x - 1 - 4 = 0
Simplify the non-algebraic terms.
-x² - 2x - 5 = 0
Use Quadratic Formula to solve for x.
Quadratic formula: x = -b ± √(b² - 4ac)
2a
a = the coefficient of x² = -1
b = the coefficient of x = -2
c = the unit term = -5
So x = -(-2) ± √ [(-2)² - 4(-1 x -5)]
2(-1)
x = 2 + √-16 or x = 2 - √-16
-2 -2
This is where the evaluation ends, since the square root of minus sixteen cannot be evaluated. x hence is equal to a complex number. The above are the two values for x.
Next step is to put it in "a + bi" form.
x = 2 + √-16 ÷ -2 = 2 + √-16 x (-2)⁻¹
So x = 2 + √-16 [ (-2)⁻¹]
where
a is 2;
b is √-16
i is [(-2)⁻¹]
