Micah found the vertex for the function y= -9.5x? 47.5x+ 63 as shown. Find and correct Micah's error. Explain the error?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as Micah's workings is not attached. So, there's no way to determine where Micah's error is.
However, I'll solve for the vertex of the given function.
Given
[tex]y = -9.5x^2 + 47.5x + 63[/tex]
Vertex, V is of the form:
[tex]V= (h,k)[/tex]
Where
[tex]h = -\frac{b}{2a}[/tex]
and
[tex]k = f(h)[/tex]
Solving for h:
[tex]y = -9.5x^2 + 47.5x + 63[/tex]
[tex]y = ax^2 + bx + c[/tex]
So:
[tex]a = -9.5[/tex]
[tex]b = 47.5[/tex]
[tex]c = 63[/tex]
[tex]h = -\frac{b}{2a}[/tex]
[tex]h = -\frac{47.5}{2 * -9.5}[/tex]
[tex]h = -\frac{47.5}{-19}[/tex]
[tex]h = \frac{47.5}{19}[/tex]
[tex]h = 2.5[/tex]
Solving for k
[tex]k = f(h)[/tex]
[tex]k = f(2.5)[/tex]
Substitute 2.5 for x in [tex]y = -9.5x^2 + 47.5x + 63[/tex]
[tex]k = -9.5 * 2.5^2 + 47.5* 2.5 + 63[/tex]
[tex]k = -59.375+ 118.75 + 63[/tex]
[tex]k = 122.375[/tex]
Hence:
The vertex is
[tex]V = (2.5,122.375)[/tex]
Answer:
if ur doing savvas
Step-by-step explanation:
answer for the first one is:
Micah used the wrong sign for b in the formula x=-b/2a
answer for the second one is:

The average cost of a home in a certain neighborhood ranges from $225,000 to $385,000. Write an absolute value inequality to model the average cost, C. of a home in this neighborhood.
Answer:
D. |C -305,000| ≤ 80,000
Step-by-step explanation:
Such an equation will say that the difference from the average of these values is at most half of their difference.
| C -(225000+385000)/2 | ≤ (385000 -225000)/2
|C -305,000| ≤ 80,000 . . . . . matches choice D

Answer:
candy 7
packs 5
Step-by-step explanation:
Answer:
Option A!
Step-by-step explanation:
Hey there!
To figure out the ratio of candies per packs, we divide 21 (candy) by packs (3) and we get 7. This means that there are 7 candies per pack! So, in 1 pack, there are 7 candies and when there are 35 candies, we divide 35 by 7 and get 5.
So, in one pack there are 7 candies and there are 35 candies in 5 packs.
Option A. Candy: 7 Packs:5

I need help graphing 2x - 6y = 42 I'm just really lazy
Answer:
We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)
Step-by-step explanation:
Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)
Raina corre 7 millas en 50 minutos. A esta misma tasa, ¿qué distancia en millas correría en 75 minutos?
Responder:
10.5 millas
Explicación paso a paso:
50 / 7 = 0.14
0.14 * 75 = 10.5
Espero que esto ayude :)
Given parameters:
Distance covered by Raina = 7 miles
Time taken = 50 minutes
Unknown:
Distance covered in 75 minutes = ?
To solve this problem, we have to find the speed of Raina during the first 50 minutes.
Speed is the distance covered with time.
Speed = [tex]\frac{distance}{time taken}[/tex]
Input the parameters and solve;
Speed = [tex]\frac{7 miles }{50 minutes}[/tex] = 0.14miles/min
Now, to find the distance covered in the second run;
Distance = speed x time taken
= 0.14miles/min x 75min
= 10.5miles
The distance covered in miles is 10.5miles
Find the value of x so that the function has the given value.
k(x)=6x−1/2; k(x)=18
Answer:
x = [tex]\frac{37}{12}[/tex]
Step-by-step explanation:
Given k(x) = 6x - [tex]\frac{1}{2}[/tex] and k(x) = 18, the equate the right sides, that is
6x - [tex]\frac{1}{2}[/tex] = 18 ( multiply through by 2 to clear the fraction )
12x - 1 = 36 ( add 1 to both sides )
12x = 37 ( divide both sides by 12 )
x = [tex]\frac{37}{12}[/tex]

6≥−6(a+2) solve and find the awnser
Answer:
[tex] - 3 \geqslant a[/tex]
Step-by-step explanation:
[tex]6 \geqslant - 6(a + 2)[/tex]
distribute -6 inside the parentheses
[tex]6 \geqslant - 6a - 12[/tex]
add 12 to both sides
[tex]18 \geqslant - 6a[/tex]
divide by -6 to isolate the variable
[tex] - 3 \geqslant a[/tex]
Answer:
-3<=a
Step-by-step explanation:
1. Get the -6 away, so multiply everything by -6. 6*-6 >= -6*-6(a+2)
2. This becomes -1 <= a+2 Since if you multiply or divide anything by a negative number, you have to reverse the inequality sign.
3. Subtract 2 to get a by itself -1-2 >= a
4. This becomes -3 >= a which is the right answer.
(Just so you know >= and <= means less than or equal to and more than or equal to.)

if f(x) =- 3x - 9, find f(5)
The value of f(5) will be "-24".
Polynomial functionsA function would be an equation that typically contains only non-negative integers (-) powers or even just positive integer (+) multipliers of variables, such as the quadratic function, cubed equation, and so forth, is considered as Polynomial functions.
According to the question,
The given function is:
f(x) = -3x - 9
By substituting "5" in place of "x", we get
→ f(5) = -3(5) - 9
By solving the bracket, we get
= -15 - 9
= -24

1. twice the square of the sum of a number and 3 is 98.find the number
Answer:
Step-by-step explanation:
Let the number be x.
twice the square of the sum of a number and 3 is expressed as;
2(x+3)²
If the expression is equal to 98, then;
2(x+3)² = 98
divide both sides by 2;
2(x+3)²/2 = 98/2
(x+3)² = 49
square root both sides
√(x+3)² = √49
x+3 = ±7
x = ±7-3
x = 7-3 or -7-3
x = 4 or -10
Hence the number is 4 or -10
The number is -4 or 10
Let n represent the unknown number
The following equation can be used to summarise the information given in the question
2 × n² = 98
The first step to take in order to determine the value of n is to divide both sides of the equation by 2
n² = 98/2
n² = 49
The second step is to determine the square root of both sides of the equation
n =√49
n =-7 or +7
The number = - 7 + 3 = - 4 or 7 + 3 = 10
