Answer:
[tex] y = 6 \sqrt{3} \: units[/tex]
Step-by-step explanation:
In order to find the value of y, first we need to find the length of the perpendicular dropped from one of the vertices of the triangle to its opposite side.
By geometric mean theorem:
Length of the perpendicular
[tex] =\sqrt{9\times 3}[/tex]
[tex] =\sqrt{27}\: units [/tex]
Next, by Pythagoras theorem:
[tex] {y}^{2} = {9}^{2} + {( \sqrt{27} )}^{2} \\ \\ {y}^{2} = 81 + 27 \\ \\ {y}^{2} = 108 \\ \\ y = \sqrt{108} \\ \\ y = \sqrt{36 \times 3} \\ \\ y = \sqrt{ {6}^{2} \times 3} \\ \\ y = 6 \sqrt{3} \: units[/tex]
A new car is purchased for 23700 dollars. The value of the car depreciates at
13% per year. To the nearest year, how long will it be until the value of the car
is 8000 dollars?
Answer:
5 years (about)
Step-by-step explanation:
$23,700 X .13 = $3,081
$3,081 X 5 = $15,405
$23,700 - $15,405 = $8,295
Good luck! hope this helps.

7.8 is what percent of 78?
Answer:
10 %
Step-by-step explanation:
let the percent be x
according to the question
7.8 = x % 0f 78
7.8 = x /100 * 78
7.8*100 = 78x
780 = 78x
780/78 = x
10 = x
Answer:
10 percent
Step-by-step explanation:
7.8 is ? of the number 78.
So, we will multiply 7.8 by 100.
7.8 x 100 = 780
Now, we will divide 780 by 78.
780/78 = 10
So, our answer is 10.
Or, you can divide:
78 divided by 7.8 is 10

2ax-6ay+bx-3by
2ax+bx -6ay-3by
x(2a+b) -3y(2a+b)
(2a+b) (x-3y)
Answer:
Step-by-step explanation:
2ax -6ay +bx -3by
take common from first two terms and take common from third and fourth term
=2a(x-3y)+b(x-3y)
take common (x-3y) is common
=(x-3y)(2a*1+b*1)
=(x-3y)(2a+b)
Find each product.
1. 2x(x^2-6x+3)
2. 2a^2(5b^2 + 3ab + 6a + 1)
Given:
The expressions are:
[tex]2x(x^2-6x+3)[/tex]
[tex]2a^2(5b^2+3ab+6a+1)[/tex]
To find:
The product of each expression.
Solution:
According to the distributive property of multiplication over addition, we get
[tex]a(b+c)=ab+ac[/tex]
The first expression is:
[tex]2x(x^2-6x+3)[/tex]
Using distributive property of multiplication over addition, we get
[tex]2x(x^2-6x+3)=(2x)(x^2)+(2x)(-6x)+(2x)(3)[/tex]
[tex]2x(x^2-6x+3)=2x^3-12x^2+6x[/tex]
Therefore, the product of [tex]2x(x^2-6x+3)[/tex] is [tex]2x^3-12x^2+6x[/tex].
The second expression is:
[tex]2a^2(5b^2+3ab+6a+1)[/tex]
Using distributive property of multiplication over addition, we get
[tex]2a^2(5b^2+3ab+6a+1)=(2a^2)(5b^2)+(2a^2)(3ab)+(2a^2)(6a)+(2a^2)(1)[/tex]
[tex]2a^2(5b^2+3ab+6a+1)=10a^2b^2+6a^3b+12a^3+2a^2[/tex]
Therefore, the product of [tex]2a^2(5b^2+3ab+6a+1)[/tex] is [tex]10a^2b^2+6a^3b+12a^3+2a^2[/tex].

What is the translation shown in the graph?
Answer:
The shape is translated four units left, and 2 units up, therefore the answer would be x=-4 and y=+2
Answer:
P= (1,-1)= P'= (-3,1)
T=(4,-1)=T'= (0,1)
R=(5,1)=R'= (1,3)
A= (5,3)=A'= (1,5)
So you would move the points 4 units across (left) and 2 units up (2,-4)
I would think your answer is right, it would be the second choice. Its just a little hard to determine because you would use the method of moving the point but to double check you would use one of the points, for example (1,-1) you would do 1+2-4 to see if you would get -3 and do the same with -1, -1+2-4. I hoped this helped!

Answer:
Step-by-step explanation:
126 + 44 = 170 ( total for under 25s)
186 - 56 = 130 (online for 25s - 50s)
154 - 58 = 96 ( in stores for aboves 50s)
314 for ONLINE TOTAL
196 for IN STORES TOTAL

A = 170
B = 56
C = 96
D = 96 - 58 = 38

Answer:
y = 0
Step-by-step explanation:
Let's use the addition method.
2x + y - 10 = 0
x - y - 5 = 0
Write the first equation as is. Write below it the second equation multiplied by -2 on both sides. Then add the equations.
2x + y - 10 = 0
(+) -2x + 2y + 10 = 0
--------------------------------
3y = 0
Divide both sides by 3.
y = 0
Answer: y = 0
A retail lumber yard plans to make a garden sales area in a rectangle adjoining the main store as shown below. The garden area will be fenced on three sides and the fourth side will be the wall of the store. The area must be about 8, 000 square feet using all 300 feet of fencing. Use algebra to find the length and width of the garden sales area. Round your answers to the nearest foot.
Answer:
The area could be 50x250 or 125x100
Step-by-step explanation:
L+2W = 350
LW = 12500
L = 350-2W
(350-2W)W = 12500
350W - 2W^2 = 12500
W = 50,125
L = 250,100
So, the area could be 50x250 or 125x100

what are the domain and range of the function represented by the set of ordered pairs {(-6, 5), (-3, 2), (-1, 0), (5, -4)}
Answer:
[tex]\text{Domain: }\{-6, -3, -1, 5\}\\\text{Range: }\{-4, 0, 2, 5\}[/tex]
Step-by-step explanation:
The domain of a function represents the range of x-values that the function has. The range of a function represents the range of y-values that the function has.
Coordinates are written as (x, y). Thus, the domain of these ordered pairs include the x-values of each ordered pair. Similarly, the range of these ordered pairs include the y-values of each ordered pair. Therefore, we have:
[tex]\text{Domain: }\{-6, -3, -1, 5\}\\\text{Range: }\{-4, 0, 2, 5\}[/tex]
