The equation of the parabola that has the vertex at point (2,-11) and passes through the point (0,5) is y = 4 (x - 2)² - 11.
What is Parabola?A parabola is a two dimensional figure on a plane which is U shaped and any point on the parabola is at an equal distance from a fixed point called focus and a fixed line called directrix.
The general form of a parabola is,
y = a (x - h)² + k
where (h, k) is the vertex.
Given vertex is (2, -11).
Equation is,
y = a(x - 2)² - 11
Also, given that the parabola passes through the point (0, 5).
Substituting,
5 = a (0 - 2)² - 11
⇒ 5 = 4a - 11
⇒ a = 4
So the required equation is, y = 4 (x - 2)² - 11.
Hence the equation of the given parabola is y = 4 (x - 2)² - 11.

Answer:
a. 3/4 inches per minute
b. -1 1/8 inches per minute
c. B is fastest; 1 1/8 is more than 3/4
Step-by-step explanation:
A change is a difference. A rate of change is one difference divided by another, usually the change in y-value divided by the change in x-value.
__
a.The change in elevation is the difference between the elevation at the end of the period (6 inches) and the elevation at the beginning of the period (3 inches). The change in time period is the difference between the end time (8 min) and the beginning time (4 min).
change in elevation per minute = (6 -3 inches)/(8 -4 min)
= (3 inches)/(4 min) = 3/4 inches/minute
__
b.Similarly, ...
change in elevation per minute = (3 -7 1/2 inches)/(18 -14 min)
= (-4 1/2 inches)/(4 min) = -1 1/8 inches/minute
__
c.We know that 3/4 is more than -1 1/8, but when we talk about the "fastest rate of change", we're generally interested in the magnitude--the value without the sign. That means we understand a rate of change of -1 1/8 inches per minute to be "faster" than a rate of change of 3/4 inches per minute.
The rate of change from Part B is fastest. 1 1/8 inches per minute is more than 3/4 inches per minute.

what is 4 1/9 + 8 2/3 as a fraction or as a whole or a mixed number?
Answer:
13 7/9
Step-by-step explanation:
You have two mixed numbers right now, so the first step to take would be to add the integers 4 and 8 since those numbers are limited by fractions (1/9 and 2/3 are limited as fractions). This would equal 13, and now you can move on to the fractions 1/9 and 2/3. In order to add those, you will have to find the LCM or the least common multiple, which in this case is 9 since 3 is a multiple of 9 (and 9 is obviously a multiple of 9). Knowing, you would have to convert the 2/3 into something ___/9, which would be 6/9. Adding those two together would result in 7/9. Combine that with the integer 13, and you have 13 7/9. Hope this helps!
Slope:
Y-intercept=
Equation Y=
Answer:
Slope = -3
Y-intercept = (0,-4)
Equation = -3x-4
Step-by-step explanation:
Slope is [tex]\frac{rise}{run}[/tex] or [tex]\frac{Y2-Y1}{X2-X1}[/tex]. Apply this from the data in the table, for example:
[tex]\frac{5-8}{-3-(-4)} = \frac{rise}{run}\\ \frac{-3}{1} = \frac{rise}{run}\\\\-3= \frac{rise}{run}[/tex]
Y-intercept is located where x=0. If we look at the table, we will find that when x=0, y=-4. If we turn it into a (x,y) point format, we will get (0,4).
The function can be found using the Y-intercept and the slope. Since at x=0, y=-4, we know that the function must have a -4 in it, therefore: [tex]y = x-4[/tex]. Our function decreases by 3 for every positive x and increases by 3 for every negative x, therefore [tex]y = -3x-4[/tex].

Which expression shows 48 +66 rewritten as the greatest common factor multiplied by the sum of two
1.
numbers?
OA. 3(16 +22)
OB. 3(45 + 63)
O C. 6(8 + 11)
O D. 6(42 + 60)
The expression is rewritten as the greatest common factor multiplied by the sum of two numbers is: 6*(8 + 11)
How to rewrite the expression?
First, we need to find the greatest common factor between 48 and 66.
To find it, we can write both of these as a product of its prime factors, we get:
48 = 2*24 = 2*2*12 = 2*2*2*6 = 2*2*2*2*3
66 = 2*33 = 2*3*11
The greatest common factor that we can make is 2*3 = 6
Then we rewrite the numbers as:
48 = 6*8
66 = 6*11
Now we can rewrite our expression:
48 + 66 = 6*(8 + 11)
So the correct option is C

For which values of k would the product of k/3 X 12 be greater than 12
Answer:
[tex]\text{k = 4, 5, 6, 7, 8... and onwards}[/tex]
Step-by-step explanation:
The product of k/3 and 12 be greater than 12.
⇒ k/3 × 12 > 12
The first step in determining the possible values of "k" is to simplify the left-hand-side (L.H.S) of the inequality.
⇒ (12 × k)/3 > 12
⇒ (12 ÷ 3) × k > 12
⇒ (4) × k > 12
The next step in determining the possible values of "k" is to isolate the variable. To do this, we can divide 4 both sides.
⇒ [4 × k]/4 > 12/4
⇒ k > 12/4
⇒ k > 3
To satisfy the inequality, the value of k must be greater than 3. Thus, the values of k could be [tex]\text{4, 5, 6... }[/tex] and so on.

The length of a rectangular garden is 9 feet longer than its width. If the garden's perimeter is 206 feet, what is the area of the garden in square feet?
Answer:
Area of rectangular garden is 2632 feet²Step-by-step explanation:
Given that length of Rectangular garden is 9 feet more than its width and perimeter of garden is 206 feet.
Let's assume length of Rectangular garden be x + 9 feet and width be x feet respectively. Firstly using the formula of Perimeter of rectangle we'll find the length and width of the garden.
[tex] \\ \\ \dashrightarrow \: \: { \underline { \boxed{ \pink{ \sf {Perimeter _{(rectangle)} = 2(L + W)}}}}} \\ \\ [/tex]
Substituting the required values:
[tex]\\[/tex]
[tex]\dashrightarrow \sf \: \: 2(x + 9 + x) = 206 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: 2x + 18 + 2x = 206 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: 4x + 18 = 206 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: 4x = 206 - 18 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: 4x = 188 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: x = \dfrac{188}{4 } \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: x = 47 \\ \\ [/tex]
Hence,
Length of garden = x + 9 = 47 + 9 = 56 feetWidth of garden = x = 47 feet[tex]\\[/tex]
Now,
[tex] \\ \dashrightarrow \: \: { \underline { \boxed{ \pink{ \sf Area _{(rectangle)} = Length \times Width }}}} \\ \\ [/tex]
Substituting the required values:
[tex]\\[/tex]
[tex]\dashrightarrow \sf \: \: Area = 56 \times 47 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: Area = 2632~ ft^2 \\ \\ [/tex]
Hence,
Area of rectangular garden is 2632 feet²Answer:
Area of rectangular garden is 2632 feet²
Step-by-step explanation:
Given:-
Length of Rectangular garden is 9 feet more than its width perimeterof garden is 206 feet.To find :-
The area of rectangular gardenSolution:-
Let the length of Rectangular garden be x + 9 feet and width be x feet .
We know that , the formula of Perimeter of rectangle is 2 ( L + B )
putting the known values to find the dimensions ,
2 ( L + B ) = 206 feet
2 ( x + 9 + x ) = 206 feet
4 x + 18 = 206 feet
x = 47 feet
putting the values of x in the equation ,
Length :- 56 feet
width :- 47 feet
Now , area of rectangular garden :- L×B
Area => 56×47 feet²
Area => 2632 feet²
