Answer:
In algebra, quadratic functions are any form of the equation y = ax2 + bx + c, where a is not equal to 0, which can be used to solve complex math equations that attempt to evaluate missing factors in the equation by plotting them on a u-shaped figure called a parabola. The graphs of quadratic functions are parabolas; they tend to look like a smile or a frown.
Step-by-step explanation:
does this help?
Answer:
The properties that are universal to all quadratic functions are:-
The graph of a quadratic function is always parabola that either poems from the upward or from the downwards .The domain of a quadratic function is all real numbers and The vertex is the lowest point when the parabola opens upward while the vertex is highest at the point when the parabola opens downwards.The places where we might see parabolas in the real world are :-
In the fact parabolas can be seen everywhere in nature and as well as the man -made items .

Every day, Krysta's burrito stand uses 1 7/10 bags of tortillas. How many days will 8 1/2 bags of tortillas last?
Write your answer as a fraction or as a whole or mixed number.
Answer:
5 days
Step-by-step explanation:
If you write it out it will look like this 8 1/2÷1 7/10
since you can't divide mixed fractions very easily, you make them improper fractions. 8 1/2 -> 17/2 1 7/10 -> 17/10
So it looks like 17/2÷17/10
because of maths you have to turn 17/10 into 10/17
And when you do the maths (multiply it together) you get 5
Answer:
5 days
Step-by-step explanation
1.turn 8 1/2 back to its original form which is 17/2
2. multiply by 5 because 2 times 5 is 10 which is the number we need the make the denominators even and because we multiplied by 5 on the bottom we multipliy by 5 on the top to make it even which is 85/10
3. put 1 7/10 back to its original form which is 17/10, and because 85 divided by 17 is 5 your answer would be 5 days

Find the area of the figure and choose the appropriate result.
Answer:
A- 24m
B- 18.9
C. 11.4
Total- 54.3
Step-by-step explanation:
Answer:
41.7 square meters
Step-by-step explanation:
First, rectangle A:
4 x 6 = 24 square meters
Second, rectangle B:
We know the length of this section is 3.5m. For the height/width, we can look at rectangle C. The height of C is 3.8m, and we see the part of C that is NOT part of B is 2m long. So we subtract 2 from 3.8 to find the height of B.
3.8 - 2 = 1.8m
Then, for the area of B:
3.5 x 1.8 = 6.3 square meters
Third, rectangle C:
3 x 3.8 = 11.4 square meters
Add up areas of A, B, C:
24 + 6.3 + 11.4 = 41.7 square meters
There are 32 munchkins in the box. You want to distribute the munchkins to Amir and Isaac so that the ratio of Amir's munchkins to Isaacs is 5:8.
How many munchkins will each person get? Show/explain your work
Answer:
Amir will get 160/13 or 12 [tex]\frac{4}{13}[/tex] and Isaac will get 20 [tex]\frac{9}{13}[/tex]
Step-by-step explanation:
Lets say that the ratio is [tex]5x:8x[/tex]. Then, let's put this into an equation:
[tex]5x+8x=32[/tex]
Then, if we solve, we get:
[tex]13x=32, x=\frac{32}{13} \text{ or } 2\frac{6}{13}\\[/tex]
Then, we know that Amir's share is [tex]5x[/tex], so [tex]\frac{32}{13}\cdot5=160/13 \text{ or } 12 \frac{4}{13}[/tex].
Then, Isaacs share is [tex]8x[/tex], so [tex]8\cdot\frac{32}{13}=20\frac{9}{13}[/tex]
Hope it helps!!
Answer:
Amir = 12 and Isaac = 20
Step-by-step explanation:
Given
[tex]Amir : Isaac = 5 : 8[/tex]
[tex]Munchkins = 32[/tex]
Required
Amount of munchkins given to each person
For Amir, the amount is calculated as:
[tex]Amir's = \frac{Amir}{Amir + Isaac} * Munchkins[/tex]
[tex]Amir's = \frac{5}{5+8} * 32[/tex]
[tex]Amir's = \frac{5}{13} * 32[/tex]
[tex]Amir's = \frac{5 * 32}{13}[/tex]
[tex]Amir's = \frac{160}{13}[/tex]
[tex]Amir's \approx 12[/tex]
For Isaac, the amount is calculated as:
[tex]Isaac's = \frac{Isaac}{Amir + Isaac} * Munchkins[/tex]
[tex]Isaac's = \frac{8}{5 + 8} * 32[/tex]
[tex]Isaac's = \frac{8}{13} * 32[/tex]
[tex]Isaac's = \frac{8 * 32}{13}[/tex]
[tex]Isaac's = \frac{256}{13}[/tex]
[tex]Isaac's \approx 20[/tex]

A triangle has vertices at (3, 5), (−5, 3), and (−3, 4). What are the coordinates of the vertices of the image after the translation (x, y) - (x + 3, y − 1)?
Answer:
(6,4), (-2,2), (0,3)
the triangle is translated 3 units to the right and 1 unit down
Step-by-step explanation:
given vertices :
(3,5), (-5,3), (-3,4)
in the given co ordinates the first one corresponds to the x co ordinate and
the second one corresponds to the y co ordinate
after traslation :
(x,y) - > (x+3, y - 1) (function)
new 3 co ordinates are:
(3+3, 5-1), (-5+3,3-1), (-3+3,4-1)
= (6,4), (-2,2), (0,3)
the triangle is translated 3 units to the right and 1 unit down

A company ordered 15 boxes of lunch from a deli for $131.25. Each boxed lunch cost the same amount. Which equation represents the proportional relationship between y, the total cost of the boxed lunches, and x, the number of boxed lunches? *
A 131.25x =15y
B 8.75x =15y
C 8.75x = y
D 87.50x = y
