Equation of a parabola is given by y = a(x - h)² + k
where:
(h, k) is the vertex33.
Looking at the graph find the vertex, vertex is at (-1, 4)
Take one point: (1, 0)
Substitute (h, k) = (-1, 4) and (x, y) = (1, 0) into equation to find value of a:
0 = a(1 - (-1))² + 40 = a(2)² + 44a + 4 = 04a = -4a = -1Now equation:
y = a(x - h)² + k
y = -1(x - (-1))² + 4
y = -(x + 1)² + 4
y = -(x² + 2x + 1) + 4
y = -x² - 2x - 1 + 4
y = -x² - 2x + 3
34.
The vertex is at (h, k) = (-2, -1) and the curve passes through (x, y) = (0, 3)
Find value of a:
y = a(x - h)² + k3 = a(0 - (-2))² - 13 + 1 = a(2)²4a = 4a = 1Now equation:
y = a(x - h)² + k
y = 1(x - (-2))² - 1
y = 1(x + 2)² - 1
y = (x² + 4x + 4) - 1
y = x² + 4x + 3
Answer:
[tex]\textsf{33.} \quad y=-x^2-2x+3[/tex]
[tex]\textsf{34.} \quad y = x^2+4x+3[/tex]
Step-by-step explanation:
Question 33Factored form of a quadratic equation:
[tex]\boxed{y=a(x-r_1)(x-r_2)}[/tex]
where:
a is the leading coefficient.r₁ and r₂ are the roots.From inspection of the graph:
r₁ = -3r₂ = 1vertex = (-1, 4)Substitute the roots and the vertex into the formula and solve for [tex]a[/tex]:
[tex]\begin{aligned}y & =a(x-r_1)(x-r_2)\\\implies 4 & = a(-1-(-3))(-1-1)\\4 & = a(2)(-2)\\4 & = -4a\\-4a & = 4\\\dfrac{-4a}{-4} & = \dfrac{4}{-4}\\a & = -1\end{aligned}[/tex]
Substitute the found value of [tex]a[/tex] and the roots into the formula and rewrite in standard form:
[tex]\begin{aligned}y & =a(x-r_1)(x-r_2)\\\implies y & = -1(x-(-3))(x-1)\\y & = -(x+3)(x-1)\\y & = -(x^2+2x-3)\\y & = -x^2-2x+3\end{aligned}[/tex]
Therefore, the equation of the parabola in standard form is:
[tex]y=-x^2-2x+3[/tex]
Question 34Vertex form of a quadratic equation:
[tex]\boxed{y=a(x-h)^2+k}[/tex]
where:
(h, k) is the vertex.a is some constant.From inspection of the graph:
Vertex = (-2, -1) ⇒ h = -2 and k = -1y-intercept = (0, 3)Substitute the vertex and y-intercept into the formula and solve for [tex]a[/tex]:
[tex]\begin{aligned}y & = a(x-h)^2+k\\\implies 3 & = a(0-(-2))^2+(-1)\\3 & = a(0+2)^2-1\\3 & = 4a-1\\3 +1& = 4a-1+1\\4 & = 4a\\4a & = 4\\\dfrac{4a}{4} & = \dfrac{4}{4}\\a & = 1\end{aligned}[/tex]
Substitute the found value of [tex]a[/tex] and the vertex into the formula and rewrite in standard form:
[tex]\begin{aligned}y & = a(x-h)^2+k\\\implies y & = 1(x-(-2))^2+(-1)\\y & = (x+2)^2-1\\y & = (x+2)(x+2)-1\\y & = x^2+4x+4-1\\y & = x^2+4x+3\end{aligned}[/tex]
Therefore, the equation of the parabola in standard form is:
[tex]y & = x^2+4x+3[/tex]

O Alex wrote checks for $42.50 more than the amount he had in his checking account.
O Alex is still able to write checks up to a total of $42.50.
O The bank deleted $42.50 from Alex's checking account
Answers
Answer:
The answer is that Alex wrote checks for 42.50 more than the amount he had.
Step-by-step explanation:
If he has -42.50 that means he owes the bank 42.50 the only way he would owe the bank that much is if he spent 42.50 that he didn't have.

Xander and Pedro are at an ice cream social. For every scoop of ice cream, Xander uses /8 eighth cup of fruit topping. Pedro uses one more tablespoon of fruit topping than the number of scoops. If Xander and Pedro each use the same amount of fruit topping, how many scoops of ice cream does each use?
Answers
9514 1404 393
Answer:
1 scoop
Explanation:
There are 16 tablespoons in 1 cup, so Xander uses (1/8)·(16 tbsp) = 2 tbsp of topping for each scoop of ice cream.
For 1 scoop of ice cream, Pedro will use 1+1 = 2 tbsp of topping.
Hence, both use the same amount of topping (2 tbsp) for 1 scoop of ice cream.

The value of A from the given expression is 4288.5
Solving exponential equationsExponential equations are inverse of logarithmic equation and the standard form of the equation is given as:
y = ab^x
Given the expression below:
A = 3000(1+0.018/12)^(12*2)
Simplify for the value of A
A = 3000(1+0.015)^24
A = 3000 (1.015)^24
A = 3000 (1.4295)
A = 4288.5
Hence the value of A from the given expression is = 4288.5

Answer:
x = 32
Step-by-step explanation:
x - 7 = 25
To solve equations, you do the some thing to both sides to isolate x.
After adding 7 to both sides we have:
x = 32
Answer:
x = 32
Step-by-step explanation:
⇒ Isolate the variable x by adding 7 to both sides:
x – 7 + 7 = 25 + 7
⇒ Evaluate the equation to finally get:
x = 32

a group of friends every time they play a game of marbles, they lose 5 marbles as it’s a big playground and they can’t be bothered to look for marbles that roll away somewhere. every time a game of marbles ends (each game takes 10-15 minutes), they collect all their marbles in a big box, hide it behind a tree, and go for a quick run. every time these kids hide all their marbles in a box behind the tree, a very intelligent squirrel sneaks up to the box, and if there are more than 12 marbles in it, the squirrel steals 3 marbles and runs off. if this group of kids started with 120 marbles in total, how many games can they play in total before they have less than 10 marbles left (given that they lose some marbles each time they play, and a squirrel steals some marbles each time they go for a run).
Answers
Answer:
14 gamesStep-by-step explanation:
Initial number of marbles = 120Lost at every game = 5Stolen by a squirrel = 3Left = less than 10Let the number of games be x
then lost marbles = 5xstolen marbles = 3xInequality:
120 - 5x - 3x < 10120 - 8x < 10110 < 8xx > 110/8x > 13 rounded downSince there should be more than 0 left, another inequality for it:
120 - 8x > 0120 > 8x x < 15So 13 < x < 15, which leaves us with 14

What is y = − 3/10 x − 8 written in standard form?
Answers
Answer:
3x + 10 y = -80
Step-by-step explanation:
We are given the equation y = −3/10x − 8 and we want to write it in standard form.
Standard form is written as ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot equal 0 and a cannot be negative.
The equation is currently is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.
As you can see, in standard form, x and y are on both sides, but in slope-intercept, the equation is solved for y.
So, to start, we can add 3/10x to both sides.
y = -3/10x - 8
+3/10x +3/10x
_______________
3/10x + y = - 8
Now, we have x and y on the same side, but remember that the the coefficients should be integers (non-fractions).
So, we need to clear the fraction.
Multiply both sides by 10.
10(3/10x + y) = 10(-8)
3x + 10y = -80
