Answer:
p = 3, q = 2/3, r = 14/3Step-by-step explanation:
Given equationy = 3x² - 4x + 6To findThe constants p, q, r when
3x² - 4x + 6 = p(x - q)² + rSolutionThe least value is at vertex of the parabola ax² + bx + c, with positive a
x and y -coordinates of the vertex is:
x = -b/2a = - (-4)/(2*3) = 2/3y = 3(2/3)² - 4(2/3) + 6 = 3(4/9) - 8/3 + 6 = 4/3 - 8/3 + 6 = 14/3The vertex form is:
y = a(x-h)² + k, where (h, k) is the vertexApplying the same formula to our equation:
3x² - 4x + 6 = 3(x - 2/3) + 14/3The constants p, q and r are:
p = 3, q = 2/3, r = 14/3HELP ME PLEASE!! <3

ROC and intro to slopes guided notes:
This graph represents the linear relationship between time and distance for both Car 1 and Car 2.
Slope of Car 1 = 1 Speed of Car 1 = 1 mi
min
Speed of Car 2 = 1 mi 2 min
How can you determine by looking at the graph which car is moving at a faster rate? The the line, the the slope.
Car 1 is moving at a speed than car 2.
Answer:
Step-by-step explanation:
The steeper the line (graph), the greater the slope and the greater the speed of that particular car. It is instantly obvious that of the two lines shown, the yellow graph has the greater slope and thus the greater speed.
"The steeper the line, the greater the slope(speed). "Car 1 is moving at a speed than car 2."

Item 10 The endpoints of the directed line segment AB are A(−1, 2) and B(7, 8). Find the coordinates of point P along AB¯¯¯¯¯¯¯¯ so that the ratio of AP to PB is 1 to 3.
Answer:
The coordinates of point P along AB is (1,6.5)
Step-by-step explanation:
We shall use the internal division formula to split AB in the ratio 1 to 3
Mathematically, that would be;
(x,y) = (nx1 + mx2)/m + n , (ny2 + my1)/m + n
m = 1 , n = 3
(x1,y1)= (-1,2)
(x2,y2) = (7,8)
(x,y) = (3(-1) + 1(7)/1+3 , (3(8) + 1(2)/1+3
(x,y) = (-3 + 7)/4, (24 + 2)/4
(x,y) = 4/4 , 26/4
(x,y) = (1, 6.5)

A rectangle has a length that is 7 inches less that twice it's width. The area of the rectangle is 72 square inches. Write an equation that represents this solution.
Answer: [tex]2x^2-7x=72[/tex] , where x= width of the rectangle ( in inches).
Step-by-step explanation:
Let x= width of the rectangle ( in inches).
Then its length = 2x-7 ( in inches).
Area of rectangle = Length × width
= (2x-7) × (x)
= 2x × x -7 ×x
= 2x²-7x
The area of the rectangle is 72 square inches.
[tex]\Rightarrow\ 2x^2-7x=72[/tex]
Hence, the equation that represents the given situation :
[tex]2x^2-7x=72[/tex]

The function f(x) = x^3 − x + 4, in continuous in the interval [1, 2]. Find the value of ‘x' at which the function takes the value 7. (Hint: Use f(x) = 7)
Answer:
2
Step-by-step explanation:
Given the function
f(x) = x^3 − x + 4 in the interval [1,2]
We are to find the value of x for which f(x) = 7
Substitute f(x) = 7 into the expression as shown!
f(x) = x^3 − x + 4
7 = x^3 − x + 4
x^3 − x + 4 -7 = 0
x^3 − x - 3= 0
x^3 -x = 3
x(x²-1) = 3
x²-1 = 3 and x = 3
x² = 3+1
x² = 4
x = ±√4
x = ±2
Since x lies within the interval, [1,2] hence the value of x is 2

A circular garden has a radius of 3 meters. What is the area of the garden? Write your answer using π. Show your work.
Answer: 9[tex]\pi[/tex]
Step-by-step explanation:
Sorry the pi sign looks weird. The formula for area of a circle is [tex]a=\pi r^2[/tex], so we have to substitute the radius with 3. The square of 3 is 9, so the answer is 9pi.

Answer:
y = 72°, x = 36°
Step-by-step explanation:
Step 1:
2x + 3x = 180° Supplementary ∠'s
Step 2:
5x = 180° Combine Like Terms
Step 3:
x = 180° ÷ 5 Divide
Step 4:
x = 36°
Step 5:
3x + y = 180° Supplementary ∠'s
Step 6:
3 ( 36 ) + y = 180° Input x value
Step 7:
108° + y = 180° Multiply
Step 8:
y = 180° - 108° Subtract
Answer:
y = 72°, x = 36°

A fruit punch recipe uses 3/4 cup of carbonated water for every 5 cups of fruit juice. Andy has only 4 cups of fruit juice. To make the same fruit punch, how much carbonated water should Andy use?
A) 3/5 cup
B) 3/10 cup
C)2/3 cup
D) 2/5 cup
Answer:
3/5 cup
Step-by-step explanation:
I start by changing the initial fraction of 3/4 into its decimal form of .75 so that it's easier to divide. I then divide it by 5 to find how much carbonated water you should use for a single cup of juice, which is .15 cups. Then, I multiply .15 times 4, which comes out to be .6, or 3/5.
Answer:
3/4 cups of carbonated water is needed by Andy to prepare 5 cups of fruit juice that means that he uses
(3/4)/5 = 3/20 cups of carbon. water for one cup of fruit juice for 4 cups he has to use (3/20)4=12/20
or 3/5 cups of carbonated water or in decimal form 0.6 cups
