Answer:
A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape.

Olivia's science class is making slime from cornstarch and glue. Olivia is helping pass out
materials. She gives each student 4 ounces of cornstarch from a 5-pound bucket. If Olivia's
class has a total of 18 students, how many ounces of cornstarch will she have left?
Answer:she will have 4.44 ounces of cornstarch left
Step-by-step explanation: 1 pound=16 ounces 16*5=80 ounces 80 ounces equal 5 pounds then you divide 80 by 18 and your answer should come out as 4.44 ounces
Amount of cornstarch left is 8 ounce
Given that;
Each student get = 4 ounce of cornstarch
Total number of student = 18 students
Total amount of cornstarch = 5 pound
Find:
Amount of cornstarch left
Computation:
Amount of total cornstarch to student = Each student get × Total number of student
Amount of total cornstarch to student = 4 × 18
Amount of total cornstarch to student = 72 ounce
1 pound = 16 ounces
So,
Total amount of cornstarch = 5 × 16
Total amount of cornstarch = 80 ounces
Amount of cornstarch left = 80 - 72
Amount of cornstarch left = 8 ounce

f(x) = -1/2x is it increasing, decreasing or constant
Answer:
The function is decreasing.
Step-by-step explanation:
f(x) = x is the parent function, when you make x negative it decreases rather than increasing. the use of the slope (1/2) doesn't change whether it it increasing or decreasing. as long as the negative sign is in front, it will decrease.

First, make the mixed numbers into improper fractions:
29/2 x 32/3
Simlify by cross cancelling if you can:
29/1 x 16/3
Then, multiply:
29/1 x 16/3 = 29 x 16/1 x 3 = 464/3
Finally, turn the new improper fraction into a simplified mixed number:
464/3 = 154 2/3

At chucky bee restaurant, the meal costs $55.25 and desserts cost $15.75 for 5 people. How much money does each person have to pay?
Answer:
$14.20
Step-by-step explanation:
First we add both the meal ($55.25) and the dessert ($15.75) to calculate the total cost which would be $77.00 Assuming the bill was evenly split among the five people, we would divide the total cost ($77.00) by all 5 people which gives us 14.20 so each person would have to pay $14.20.

Show that a to the 6th an be written as a perfect square and as a perfect cube.
Answer:
Step-by-step explanation:
a^6 = a * a * a * a * a * a You can break this into groups of 2 and groups of three.
Groups of 3
a^6 = a * a * a * a * a * a
what that means is that you have 2 groups of 3 which can be written as (a^3)^2 which means that this number is a perfect square.
Groups of 2
a^6 = a * a * a * a * a * a
What this means is that you have (a^2)^3 which is three groups of 2 members. The answer is that you have a perfect cube each member of which is a^2

I’m not very good at math and I need help
The answer would be 6.00%
Answer:
C
Step-by-step explanation:
First of all it's not that you aren't very good at math it's just that you don't YET understand the concepts,... Believe me when I say that I've been there!!!
To solve this problem you have to look at it as a solve for the unknown problem,... They say that The FORMULA (important) is the following:
S = Ar
This can be written:
S = A * r
They then say that
S = sales tax,
A = cost of the product
r = local sales-tax rate,...
THEN they start giving you information,... they say the COST of a television (cost of the product) is $400 dollars you can now enter this info in you formula,... A = cost of product,... so switch the letter with the assigned info,...
S = $400 * r
...and the sales tax is $24 dollars,... S stands for sales tax so switch the variable for the dollar amount,...
$24 = $400 * r
Now you just have to solve the equation (figure out $400 * what = $24) and easy way to do this is to simply divide $24 by $400,...
$24/$400=0.06,...
0.06 = 6.0% = 6.00%

Given f (x) = x2 – 4 and g(x) = x + 3 then g (f (2)) =
Answer:
g (f(2)) = 3
Step-by-step explanation:
f (x) = x2 – 4
g(x) = x + 3
g (f (2)) =?
Find f(2) first
f (x) = x2 – 4
f (2) = 2^2- 4
= 0
Now put this in your g(x)
g(x) = x + 3
g (f(2)) = (f(2)) + 3
And u alredy know f(2) =0, so just put it in
g (f(2)) = 0 + 3

5 1/4-2 2/3
Solve and show equations
Answer:
5 1/4 - 2 2/3 = 31/12 = 2 7/12 = 2.5833333
Step-by-step explanation:
1. Conversion a mixed number 5 1/4 to a improper fraction: 5 1/4 = 5 1/4 = 5 · 4 + 1/4 = 20 + 1/4 = 21/4
To find new numerator:
a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/4 = 20/4
b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21
c) Write a previous answer (new numerator 21) over the denominator 4.
Five and one quarter is twenty-one quarters
Conversion a mixed number 2 2/3 to a improper fraction: 2 2/3 = 2 2/3 = 2 · 3 + 2/3= 6 + 2/3 = 8/3
To find new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/3 = 6/3
b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.
Two and two thirds is eight thirds
Subtract: 21/4 - 8/3 = 21 · 3/4 · 3 - 8 · 4/3 · 4 = 63/12- 32/12 = 63 - 32/12 = 31/12
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 3 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - twenty-one quarters minus eight thirds = thirty-one twelfths.

A dance academy charges $24 per class and a one time registration fee of $15. A student paid a total of $687 to the academy. Find the number of classes the student took.
Answer:
The student took 28 classes
Step-by-step explanation:
What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.
in the figure below the measure of <1=5x°, the measure of <2=y°, and the measure of <3=85°. Find the value of each variable.
(for the first one <1=5x° I found out x=17 so I just need the rest if you can)
Answer:
y=95
Step-by-step explanation:
17x5=85
180-85=95
y=95
Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x and y is 17 and 95, respectively.
What are vertical angles?Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.
The measure of ∠1 and ∠3 will be equal since the two angles are vertical angles. Therefore, we can write.
∠1 = ∠3
5x° = 85°
x = 85° / 5
x = 17°
Also, the sum of measures ∠1 and ∠2 will be equal to 180°, this is because the two angles form a pair of linear angles. Therefore, we can write,
∠1 + ∠2 = 180°
5x + y = 180°
Substitute the value of x,
5(17°) + y = 180°
85° + y = 180°
y = 180° - 85°
y = 95°
Hence, the value of x and y is 17 and 95, respectively.
