Please help me in math. Write an equation of the parabola shown.
Answer:
[tex]y = \frac{1 }{8} {(x + 3)}^{2}[/tex]
Step-by-step explanation:
[tex]y = a(x - h)^{2} + k \\ y = a(x - ( - 3))^{2} + 0 \\ using \: points \: (1 ,\: 2) \\ 2 = a {(1 - ( - 3))}^{2} \\ 2 = a{4}^{2} \\ 16a = 2 \\ \boxed{ a = \frac{1}{8} } \\ hence \to \\ y = \frac{1}{8} (x - ( - 3))^{2} \\ y = \frac{{(x + 3)}^{2} }{8} [/tex]
Tell whether the equation represents direct variation. If it does find the
constant of direct variation. -12 + 8y +12 = 7x.
Given:
The equation is
[tex]-12+8y+12=7x[/tex]
To find:
The constant of direct variation if the given equation represents direct variation.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
We have,
[tex]-12+8y+12=7x[/tex]
[tex]8y=7x[/tex]
[tex]y=\dfrac{7}{8}x[/tex] ...(ii)
At x=0,
[tex]y=\dfrac{7}{8}(0)[/tex]
[tex]y=0[/tex]
The equation (ii) passes through (0,0). So, it represents a proportional relationship.
On comparing (i) and (ii), we get
[tex]k=\dfrac{7}{8}[/tex]
Therefore, the constant of proportionality is [tex]k=\dfrac{7}{8}[/tex].

PLEASE HELP QUICKLY!!
Answer:
79
Step-by-step explanation:
Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.

If m ∆ n means m²-2mm+n³, determine the value of 3∆2.
since m▲n=m^2-2mn+n^3
3▲2=3^2-2*3*2+2^3
=9-12+8
=17-12
=15
Done!
[tex]\large\underline{\underline{ \sf\maltese Correct \ Question :- }}[/tex]
If m ∆ n means m²-2mm+n², determine the value of 3∆2.
[tex]\large\underline{\underline{ \sf\maltese Answer :- }}[/tex]
Here we are given that m ∆ n means m² -2mn +n². And we need to find the value of 3∆2 . So let's find out what does the " ∆ " operator does.
Here we can see that m² - 2mn - n² is the whole square of ( m - n)² . A inference can be taken out that the operator " ∆ " first subtracts the two numbers and then squares the obtained value to get the result . That is ,
[tex]\sf\implies m \Delta n = ( m - n )^2 [/tex]
Now similarly let's simplify out 3 ∆ 2.
Step 1 : Subtract the two numbers :-
This means we need to subtract 2 from 3 . This will give result as ,
[tex]\sf\implies Result_1 = 3 - 2 =\pink{1} [/tex]
Step 2 : Square the obtained value :-
Here , the value obtained from step 1 is 1 and the square of 1 is 1 . So our final result would be,
[tex]\sf\implies Result_{(final)}= 1^2 = \boxed{\pink{ 1 }} [/tex]

The student council is organizing a school fair. Council members are making signs to show the prices for admission and for each game a person can play. If the school admission is $2 and the price per game is 25 cents, Let x represent the number of games. Which expression can you use to determine the total amount (in dollars) a person pays for admission and playing x games?
Answer:
$2 + 0.25x
Step-by-step explanation:
The expression would be
Let us assume the x be the number of games
And the school admission is $2 plus the price of game is 25 cents
So, based on the above information
The expression to determine the total amount is
= $2 + 0.25x

Find the missing side in each triangle using any method.
The missing side lengths of the right triangles are AC = 13 and DE = 24.
What is the Pythagorean theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given the two right triangles.
The hypotenuse of the first right triangle is given by:
AC² = 5² + 12²
AC² = 25 + 144
AC² = 169
AC = 13
The length of the leg in the second triangle is given by:
DE² = 26² - 10²
DE² = 676 - 100
DE² = 576
DE = 24
Hence, the missing side lengths of the right triangles are AC = 13 and
DE = 24.

The table below shows how the mass of household waste in the UK has changed from 2004 to 2012. Calculate the percentage of household waste recycled in 2010.
Answer:
41.5
Step-by-step explanation:
Take the amount of recycled waste and divide it by the total amount of waste. Then multiply this value by 100 to get the percentage of waste which was recycled.
9733/23454 = 0.415
0.415 x 100 = 41.5

Step-by-step explanation:Trust me it's right
Answer: Area= 18 cm; Perimeter: 18 cm
Step-by-step explanation:
1. Figure out the base and height:
Since the base is 3x-3; the height would be (3x-3)+3
2. Subsitute for x:
Base: 3(2)-3 => 6-3 => 3 cm
Height: (3(2)-3)+3 => (6-3)+3 => 3+3 => 6 cm
3. Figure out the Area:
A=b*h => A=3*6 => 18 cm
4. Figure out the perimeter:
P= 2b+2h => 2*3 + 2*6 => 18 cm
