Find the distance between points (6,5 sqaure root 2) and 4,square root 3).
Help ASAP
For this case we have that by definition, the distance between two points is given by:
[tex]d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}[/tex]
We have the following points:
[tex](6,5 \sqrt {2})\\(4,3 \sqrt {2})[/tex]
Substituting:
[tex]d = \sqrt {(4-6) ^ 2 + (3 \sqrt {2} -5 \sqrt {2}) ^ 2}\\d = \sqrt {(- 2) ^ 2 + (- 2 \sqrt {2}) ^ 2}\\d = \sqrt {4+ (4 * 2)}\\d = \sqrt {4 + 8}\\d = \sqrt {12}\\d = \sqrt {2 ^ 2 * 3}\\d = 2 \sqrt {3}[/tex]
Answer:
Option C
Answer: Third option.
Step-by-step explanation:
The distance between two points can be calculated with this formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Then, given the points [tex](6,5\sqrt{2})[/tex] and [tex](4,3\sqrt{2})[/tex], we can identify that:
[tex]x_2=4\\x_1=6\\y_2=3\sqrt{2}\\y_1=5\sqrt{2}[/tex]
Now we must substitute these values into the formula:
[tex]d=\sqrt{(4-6)^2+(3\sqrt{2}-5\sqrt{2})^2}[/tex]
We get that the distance between these two points is:
[tex]d=2\sqrt{3}[/tex]

What is the area of the polygon given below?
Answer:
186
Step-by-step explanation:
Cut it 6+7+11=24×5=120
6+11=66
120+66=186
Answer: The correct option is (A) 186 sq. units.
Step-by-step explanation: We are given to find the area of the polygon shown in the figure.
Let us divide the given polygon in two rectangles A and B as shown in the attached figure below.
The dimensions of rectangle A are
length, l = 11 units and breadth, b = 6 units.
So, the area of rectangle A is given by
[tex]AREA_A=l\times b=11\times6=66~\textup{sq. units}.[/tex]
And the dimensions of rectangle B are
length, l' = 7 + 11 + 6 = 24 units and breadth, b' = 5 units.
So, the area of rectangle B is given by
[tex]AREA_B=l'\times b'=24\times5=120~\textup{sq. units}.[/tex]
Therefore, the total area of the given polygon is given by
[tex]AREA=AREA_A+AREA_B=66+120=186~\textup{sq. units}.[/tex]
Thus, the required area of the given polygon is 186 sq. units.
Option (A) is CORRECT.

y - 4 = 3x
y-2 = 3(x – 6)
y + 4 = x
y + 6 = x - 2
Answer:
y + 4 = xStep-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept → (0, b).
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points A(0, -4) → b = -4 and B(6, 2).
Calculate the slope:
[tex]m=\dfrac{2-(-4)}{6-0}=\dfrac{6}{6}=1[/tex]
Put the value of m and of b to the equation:
[tex]y=1x-4[/tex] add 4 to both sides
[tex]y+4=x[/tex]
Without drawing the graph, find out whether the lines representing the following pair of linear equations intersect at a point, are parallel or coincident: 9x-10y=21
& 3/2x-5/3y=7/2
The easiest way to solve this question is to write out both equations in the form y = mx + c, where m is the gradient and c is the y-intercept.
a) Thus, if we start with 9x - 10y = 21, then we get:
9x - 10y = 21
(9/10)x - y = 21/10 (Divide both sides by 10)
(9/10)x = y + 21/10 (Add y to both sides)
(9/10)x - 21/10 = y (Subtract 21/10 from both sides)
Thus, our first equation may be written as y = (9/10)x - 21/10
b) Now if we take the second equation, (3/2)x - (5/3)y = 7/2, we can follow the same process to get:
(3/2)x - (5/3)y = 7/2
(9/10)x - y = 21/10 (Multiply each side by 3/5)
(9/10)x = y + 21/10 (Add y to each side)
(9/10)x - 21/10 = y (Subtract 21/10 both sides)
Thus, the second equation may be written as y = (9/10)x - 21/10.
Now you might have already realised this but the two equations are actually exactly the same; if they are the same line then they are said to be coincident.
Note that if the two lines are parallel, then their gradients (m) would be the same, but the y-intercepts (c) would be different (eg. y = 2x + 3 and y = 2x + 4 are parallel).
If they just intersect at a point, then the gradients of the lines would be different, but the y-intercepts could be the same or different (eg. y = 4x + 2 and y = 9x + 2 intersect at one point).
For them to be coincident however, both the gradient and y-intercept must be the same as only then would they be the same line.

Rebecca has 45 coins, all nickels and dimes. The total value of the coins is 3.60.How many of each type of coin does Rebecca have?
Answer:
There are 18 nickel coins and 27 dime coins
Step-by-step explanation:
Remember that
1 nickel=$0.05
1 dime=$0.10
Let
x ----> the number of nickel coins
y ---> the number of dime coins
we know that
x+y=45
x=45-y -----> equation A
0.05x+0.10y=3.60
Multiply by 100 both sides
5x+10y=360 ----> equation B
Solve the system by substitution
Substitute equation A in equation B and solve for y
5(45-y)+10y=360
225-5y+10y=360
5y=360-225
5y=135
y=27
Find the value of x
x=45-27= 18
therefore
There are 18 nickel coins and 27 dime coins
A box holds 25 pounds of cans. Each can weighs 8 ounces. How many cans does each box hold?
A- 50 cans
B- 52 cans
C- 60 cans
D- 62 cans
1 pound = 16 ounces.
1 can weighs 8 ounces, so 2 cans weigh 8 +8 = 16 ounces, which is 1 pound.
Multiply total pounds by number of cans per pound:
25 pounds x 2 cans per pound = 50 total cans.
The number of cans each box hold will be 50.
How to convert ounces to pounds?In one pound there is a total of sixteen ounces.
So it means 1 pound = 16 ounces.
Given that the weight of the can is 8 ounces it means in 2 cans there are 16 ounces which are 1 pound.
2 cans = 1 pound
Since, the box can hold only 25 pounds Hence,
25 × 2 = 50 cans so a box can hold up to 50 cans.

What is the inverse of f(x) = 6x -24
Answer:
f^(−1)(x)= x/6+4
Step-by-step explanation:
interchange the variables and solve for
y
Inverse of the given function f(x) is f⁻¹(x) = (x/6) + 4.
What is an Inverse function?It is defined as, for a one-one function each element of a range of an original function is mapped to the domain of an inverse function.Inverse of a given function is possible only of the original function is one-one and onto.
Given: Function
f(x) = 6x - 24
Let, y = 6x - 24
Now, to find the inverse of the given function we need to interchange the values of x and y and then we will solve for y.
⇒ x = 6y - 24
⇒ 6y = x + 24
Dividing both sides by 6, we get:
⇒ y = (x + 24)/6
⇒ y = (x/6) + 4
We can write it as:
f⁻¹(x) = (x/6) + 4
Therefore, the inverse of f(x) = 6x -24 is f⁻¹(x) = (x/6) + 4.

x^3 + 2x^2 + 5x + 10
Answer:
The factors of x^3+2x^2+5x+10 are (x^2+5)(x+2)
Step-by-step explanation:
x^3+2x^2+5x+10
Group the expression by two:
=(x^3+2x^2)+(5x+10)
Factor out GCF in each group.
=x^2(x+2)+5(x+2)
Note:(The binomials in parentheses should be the same, if not the same... there is an error in the factoring or the expression can not be factored.)
Now factoring out the GCF which basically has you rewrite what is in parentheses and place other terms left together:
=(x^2+5)(x+2)
Thus the factors of x^3+2x^2+5x+10 are (x^2+5)(x+2)....
