on square bcde if e is located at (4,-9) and d is located at (10,-5) find the perimeter of the square
Answer:
8[tex]\sqrt{13}[/tex] unitsStep-by-step explanation:
We know that:
P = 4aWe can find one side by distance formula:
a = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]a = [tex]\sqrt{(10 - 4)^2+(-5+9)^2} = \sqrt{36+16} = \sqrt{52} = 2\sqrt{13}[/tex]Then the perimeter is:
P = 4*2[tex]\sqrt{13}[/tex] = 8[tex]\sqrt{13}[/tex] unitsIf A and B are (-2,-2) and (2,-4). Find the coordinates P such that AP=3/7 AB and P lies on the line segment ab
Answer:
The coordinates of point P are [tex](-\frac{2}{7}, -\frac{20}{7})[/tex].
Step-by-step explanation:
Point P:
The coordinates of point P are (x,y).
AP=3/7 AB
So
[tex]P - A = \frac{3}{7}(B-A)[/tex]
We apply this both for coordinate x and coordinate y.
Coordinate x:
[tex]x - (-2) = \frac{3}{7}(2 - (-2))[/tex]
[tex]x + 2 = \frac{12}{7}[/tex]
[tex]x = \frac{12}{7} - 2 = \frac{12}{7} - \frac{14}{7} = -\frac{2}{7}[/tex]
Coordinate y:
[tex]y - (-2) = \frac{3}{7}(-4 - (-2))[/tex]
[tex]y + 2 = -\frac{6}{7}[/tex]
[tex]y = -\frac{6}{7} - 2 = -\frac{6}{7} - \frac{14}{7} = -\frac{20}{7}[/tex]
The coordinates of point P are [tex](-\frac{2}{7}, -\frac{20}{7})[/tex].

Copy and complete. Answer: (a) Increased by % (b) Increased by % (c) Decreased by % (d) Decreased by % (e) Increased by % (f) Decreased by %
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete; However, one can deduce from the options that the question refers to percentage change.
I will give two illustrations that shows how to calculate percentage change.
Illustration 1
Consider goods x with the following price change.
[tex]Old = \$45[/tex]
[tex]New = \$55[/tex]
The percentage change is:
[tex]\%Change = \frac{New - Old}{Old} * 100\%[/tex]
[tex]\%Change = \frac{55-45}{45} * 100\%[/tex]
[tex]\%Change = \frac{10}{45} * 100\%[/tex]
[tex]\%Change = \frac{1000}{45} \%[/tex]
[tex]\%Change = 22.22\%[/tex]
This means there is a 22.22% increase
Illustration 2
Consider goods x with the following price change.
[tex]Old = \$45[/tex]
[tex]New = \$35[/tex]
The percentage change is:
[tex]\%Change = \frac{New - Old}{Old} * 100\%[/tex]
[tex]\%Change = \frac{35-45}{45} * 100\%[/tex]
[tex]\%Change = \frac{-10}{45} * 100\%[/tex]
[tex]\%Change = -\frac{1000}{45} \%[/tex]
[tex]\%Change = -22.22\%[/tex]
The negative sign indicates percentage decrease
So, this means there is a 22.22% decrease

Find three consecutive even integers such that the product of the second and
third integers is equal to 35.
Step-by-step explanation:
first number=x
second number=x+2
third number=x+4
(x+2)(x+4)=35
x(x+4)+2(x+4)=35
x²+4x+2x+8=35
x²+6x+8=35
x²+6x=35-8
x²+6x=33
x²+6x-33=0
using that, you can find the first number,
then use the data to find the other two.
the sum of two integers is 310. if one of them is - 52. find the other
Answer:
Integer = 362
Step-by-step explanation:
Let the two integers be x and y
Sum of two integers, x + y = 310 ------(1)
Given one of the integer, Let x = -52
Substitute x = -52 in (1) ,
-52 + y = 310
y = 310 + 52
y = 362

What is the value of x in the equation ?
Answer: x=2
Step-by-step explanation:
15x-10=10 + 6+ 2x
15x-2x=20+6
13x=26
X=2
Answer:
x = 2
Step-by-step explanation:
2.5(6x - 4) = 10 + 4(1.5 + 0.5x)
Distribute the 2.5
15x - 10 = 10 + 4(1.5 + 0.5x)
Distribute the 4
15x - 10 = 10 + 6 + 2x
Combine like terms
15x - 10 = 16 + 2x
Add 10 to both sides
15x = 26 + 2x
Subtract 2x from both sides
13x = 26
Divide both sides by 13x
x = 2
When solving the equation x2 – 8x - 7 = ( by completing
the square, which equation is a step in the process?
Step-by-step explanation:
x²– 8x - 7 = 0
(x²-8x+16) -7 = 16
(x²-8x+16) = 16+7
(x-4)² = 23
x-4 = √23

Consider the equation y = -2x + b. Find the value of b if the line passes through (-5, 4).
Select one:
a. b = -3
b. b = 4
c. b = 2
d. b = -6
Answer:
b = -6 (Answer d)
Step-by-step explanation:
The slope-intercept equation is y = -2x + b, and we know that the line passes through (-5, 4). Substitute -5 for x and 4 for y, to obtain:
4 = -2(-5) + b, or
4 = 10 + b, or
b = -6 (Answer d)

If Andrea traveled 300 miles in 5 hours at what rate was she driving?
Answer:
60
Step-by-step explanation:
[tex]\frac{300}{5}[/tex]
60
Hence, 60 is the answer
Answer:
60 mph
Step-by-step explanation:
For this problem, we are looking at the rate, miles per hour. We know that Andrea traveled 300 miles in 5 hours, but how many miles did she travel in one hour? Let's do the math:
[tex]300[/tex]÷[tex]5=60[/tex] miles.
So, in one hours, Andrea travels 60 miles. We get the rate, 60mph.
Andrea was driving at 60 mph.

Which equation represents the general form a circle with a center at (–2, –3) and a diameter of 8 units?
x2 + y2 + 4x + 6y – 51 = 0
x² + y² – 4x – 6y – 51 = 0
x2 + y2 + 4x + 6y – 3 = 0
x2 + y2 – 4x – 6y – 3 = 0
The equation for the given circle is:
[tex]x^2 + y^2 + 4x + 6y - 3 = 0[/tex]
How to get the equation of the circle?
Remember that for a circle whose center is (a, b) and has a radius r, the equation is:
[tex](x - a)^2 + (y - b)^2 = r^2[/tex]
In this case, the center is (-2, -3) and the diameter is 8 units, so the radius is r = 4.
Then the equation is:
[tex](x + 2)^2 + (y + 3)^2 = 4^2[/tex]
Expanding the squares we get:
[tex](x^2 + 2*2*x + 4) + (y^2 + 2*3*y + 3^2) = 16\\\\x^2 + y^2 + 4x + 6y + 4 + 9 - 16 = 0\\\\x^2 + y^2 + 4x + 6y - 3 = 0[/tex]
So the correct option is the third one.

Answer:
Step-by-step explanation:
Start by looking at the face that is closest to the bottom left. It is a hexagon and it makes 1 face.
It is connected to a similar hexagon on the upper right by 6 tiles. So that adds 7 more faces.
The total is 2 hexagons + 6 rectangles = 8 faces.
Andres went out to a restaurant for dinner. His total bill before tax and tip was $27.30. He was charged an additional 9% tax and he also paid a 15% tip on the original bill.
Answer:
$25.66
Step-by-step explanation:
Given data
Total Bill before tax and tip= $27.30
Tax= 9%
Tip= 15%
Let us find the tax
=9/100*27.30
=0.09*27.30
=$2.457
Let us find the tip
=15/100*27.30
=0.15*27.30
=$4.095
Therefore his bill after tax and tip is
=27.30+2.457-4.095
=$25.66
