The midpoint of GH is M (2,2). One endpoint is H (1,9). Find the coordinates of endpoint G.
Answer:
(3,-5)
Step-by-step explanation:
Given
[tex]M = (2,2)[/tex]
[tex]H = (1,9)[/tex]
Required
Determine G
This is calculated using the following midpoint formula;
[tex]M(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
Where
[tex](x,y) = (2,2)[/tex] and [tex](x_1,y_1) = (1,9)[/tex]
Substitute these values in the formula above
[tex](2,2) = (\frac{1 + x_2}{2},\frac{9 + y_2}{2})[/tex]
Solving for [tex]x_2[/tex]
[tex]2 =\frac{1 + x_2}{2}[/tex]
Multiply both sides by 2
[tex]2 * 2 = 1 + x_2[/tex]
[tex]4 = 1 + x_2[/tex]
[tex]x_2 = 4 - 1[/tex]
[tex]x_2 = 3[/tex]
Solving for [tex]y_2[/tex]
[tex]2 = \frac{9 + y_2}{2}[/tex]
Multiply both sides by 2
[tex]2 * 2 = 9 + y_2[/tex]
[tex]4 = 9 + y_2[/tex]
[tex]y_2 = 4 - 9[/tex]
[tex]y_2= -5[/tex]
Hence, the coordinates of G is [tex](3,-5)[/tex]
x²-x-2(area)
x + 1(base)
The triangle above has an area of x2-x-2 and a
base of x + 1. What is the height of the triangle?
area of triangle formula = ½ × Base × Height
X² - X - 2 = ½ × ( X + 1) × Height
X² - X - 2 = (0.5X + 0.5)Height
Therefore,
Height = ( X² - X - 2 ) / ( 0.5X + 0.5 )

A triangle has a perimeter of 77 centimeters. Each of the two longer sides of the triangle is three times as long as the shortest side. Find the length of each side of the triangle
Answer:
a = 33cm
b = 33cm
c = 11cm
Step-by-step explanation:
Let us say that the sides of the triangle are a, b and c
The perimeter of a triangle can be calculated by adding all three sides of the triangle.
Perimeter = a + b + c
Let side c be the shortest side of the triangle.
From the statement "Each of the two longer sides of the triangle is three times as long as the shortest side" we can have that
a = 3c and b = 3c
We can input these values into the perimeter of the triangle
Perimeter = 3c + 3c + c = 77
Perimeter = 7c = 77
c = 11
The shortest side, c is = 11 cm
side a is 3 X 11 = 33cm
side b = 3 X 11 = 33 cm
How are the expressions 8 - 15 and 8 +(15) alike? How are they different?
Well, one thing they ahve in common is that they are both adding or subtracting the same numbers and of course, they are both expressions.
They are different because one expression is subtract both numbers while one expression is adding both numbers.
8 - 15 = -7
8 + 15 = 23
Best of Luck!
solve the equation for x
Answer
x = 15Step-by-step explanation:
[tex] \sf{ \frac{40}{x + 1} = \frac{15}{6} }[/tex]
Do cross multiplication
[tex] \dashrightarrow{ \sf{15(x + 1) = 40 \times 6}}[/tex]
Distribute 15 through the parentheses
[tex] \dashrightarrow \sf \: 15x + 15 = 40 \times 6[/tex]
Multiply the numbers : 40 and 6
[tex] \dashrightarrow{ \sf{15x + 15 = 240}}[/tex]
Move 15 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{15x = 240 - 15}}[/tex]
Subtract 15 from 240
[tex] \dashrightarrow \: \sf{15x = 225}[/tex]
Divide both sides by 15
[tex] \dashrightarrow{ \sf{ \frac{15x}{15} = \frac{225}{15} }}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{x = 15}}[/tex]
Hope I helped!

Min-jun has a swimming pool that needs to be drained. His pool holds
10,874.5 gallons of water and will need to drain completely in 10.7
hours. What is the change in the water level per hour for Min-jun's
swimming pool? Round your answer to the nearest hundredth.
Answer:
The change in the water level per hour for Min-Jun's swimming pool is 1016.31 Gallons per hour.
Step-by-step explanation:
Since we have a total amount of 10,874.5 gallons and 10.7 hours total to drain the full pool we divide the total amount by the total time, assuming that the pool drains at a constant rate. When we divide 10,874.5 by 10.7 we get 10.16.3084... and rounding it to the nearest hundreth or the second decimal place we get 1,016.31 gallons per hour.

Does it make sense to represent the number 15.3 using scientific notation yes or no?
Answer:
Not really. No.
Step-by-step explanation:
15.3 in scientific notation would be represented as "1.53e+1." 15.3 isn't a very large or tiny number. Usually numbers that would be represented by scientific notation would be numbers such as "600,000,000" or "0.00000012" etc. 15.3 is just a standard decimal so it's not really practical.
Hope this helps and have a nice day!

A new Youth Activity Center is being built in Hadleyville. The perimeter of the rectangular playing field is 430 yards. The length of the field is 5 yards less than quadruple the width. What are the dimensions of the
playing field?
The width is yards.
The length is yards.
Answer:
Width = 44 yards
Length = 171 yards
Step-by-step explanation:
Given:
Perimeter of the rectangular field = 430 yards.
Let:
The length of the field be L
The width of the field be W.
From the question:
The length of the field is 5yards less than quadruple the width. This implies that;
L = 4W - 5
But.
Perimeter (P) of a rectangle is given by:
P = 2(L + W) ---------------(i)
Substitute the values of P = 430, L = 4W - 5 and W into equation (i) as follows;
430 = 2(4W - 5 + W)
430 = 2(5W - 5)
430 = 10W - 10
10W = 430 + 10
10W = 440
Divide both sides by 10
W = 44
Therefore, the width of the field is 44 yards.
Remember that,
L = 4W - 5
[Now substitute W = 44]
L = 4(44) - 5
L = 176 - 5
L = 171
Therefore, the length of the field is 171 yards
9x9+3x3=
what does that equal too
Answer:
252
9x9=81 +3=84
84x3=252
Answer:
90
Step-by-step explanation
(9x9)+(3x3) so first i multiplied 9x9= 81.
then i did 3x3 which is 9
then i added 9+81=90
so the answer is 90
Given that sin(90 -5ϴ) = Cos(180 - ϴ), Find the value of ϴ
Answer:
30°
Step-by-step explanation:
[tex] \because \: \sin(90 \degree - \theta) = \cos \theta \\ \therefore \: \sin(90 \degree - 5 \theta) = \cos 5\theta....(1) \\ \\ \sin(90 \degree - 5 \theta) = \cos(180 \degree - \theta)...(2) \\ from \: (1) \: and \: (2) \\ \cos 5\theta = \cos(180 \degree - \theta) \\ 5 \theta = 180 \degree - \theta \\ 5 \theta + \theta= 180 \degree \\ 6\theta= 180 \degree \\ \theta = \frac{180 \degree}{6} \\ \\ \huge \red{ \boxed{\theta = 30 \degree}}[/tex]

Factorise :
[tex] \sf{ {x}^{2} - 4x - 21 + 10y - {y}^{2} }[/tex]
Show workings too!
Answer:
(x - y + 3)(x + y - 7)
Step-by-step explanation:
x^2 - 4x - 21 + 10y - y^2
= x^2 - y^2 - 4x -21 + 10y
= (x - y)(x + y) - 4x + 10y - 21 Now -21 = + 3 * -7 and +3x - 7x =- 4x so we try:
= (x - y + 3)(x + y - 7)
- this expands to the original expression.
Answer:
(x+y-7)(x-y+3) is your answer
Step-by-step explanation:
x²-4x-21+10y-y²
x²-4x+2²-2²-21+10y-y²

(x-2)²-(y-5)²

what sequence of transformations on the red triangle will map it onto the missing portion of the square
Answer:
Answer is C.) a 90° counterclockwise rotation about the origin and then a translation 16 units right and 16 units up
Step-by-step explanation:
Rotating the triangle 90° counterclockwise will take the triangle to 3rd quadrant and then further moving it 16 steps right will take it to 4th quadrant and followed by 16 steps upward will take it to the desired position which is in 1st quadrant.

Write each number in scientific notation.
Step-by-step explanation:
For example, in order to multiply 832,000 by 0.00035, one converts first to scientific notation as follows: (832,000)×(0.00035)=(8.32×10 5)×(3.5×10 −4)=8.32×3.5×10 5×10 −4=29.12×10 1=2.912×10 2 (in scientific notation) or 291.2 (in ordinary notation).
Answer:
0.00035 = 3.5 × 10 to the -4

Before comparing mixed fractions, let's make them inappropriate
2 1/2 = 5/2
3 1/3 = 10/3
Comparing fractions. (MMC - Maximum Common Multiple - I don't know that term in English)
2 1/2 = 5/2 = 15/6
3 1/3 = 10/3 = 30/6
30/6 > 15/6 then
3 1/3 > 2 1/2
