The roots of a quadratic function are the values of x that make the function is 0. These roots can be found by solving the equation f(x) is 0.
What is quadratic function ?A quadratic function is a type of mathematical function that can be written in the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a is not equal to 0. This type of function is called a quadratic function because the highest power of x in the function is 2.
The graph of a quadratic function is a parabola, which is a U-shaped curve. The shape of the parabola is determined by the value of the constant a. If a is positive, the parabola opens upwards and if a is negative, the parabola opens downwards.
The roots of a quadratic function are the values of x that make the function equal to 0. These roots can be found by solving the equation f(x) = 0. To solve this equation, we can use the quadratic formula, which is:
x = (-b +/- sqrt(b^2 - 4ac)) / (2a)

A triangle has side lengths of 200 units and 300 units. Write a compound inequality for the range of the possible lengths for the third side,
Answer:
100<x<500
Step-by-step explanation:
We can create a system of inequalities by using the Triangle Inequality Theorem. This theorem states that the sum of two sides on a triangle is greater than the other sides.
1.) Figure out the first inequality. This would be 300+200>x, or x<500.
2.) Figure out the second inequality. This would be x + 200 > 300, or x>100.
3.) Figure out the third inequality. This would be x + 300 > 200, or x > -100.
4.) Combine these inequalities. By combining these inequalities, we would get 100<x<500.

Write the explicit and recursive rules for a geometric sequence given a table of values.
(a) The Explicit Rule for f(n) is 0.1 × 3n The Recursive Rule for f(n) is f(n-1) × 3. (b) The Explicit Rule for f(n) is 100 × 0.1ⁿ The Recursive Rule for f(n) is f(n-1) × 0.1
What is Explicit rule ?The explicit rule states that the value of the sequence at each term is 0.1 multiplied by 3 raised to the power of n. The recursive rule states that the value of the sequence at each term is equal to the value of the preceding term multiplied by 3. This can be seen in the table of values where each value is 3 times the preceding value.
Given,
n = 0,1,2,3,4…
f(n) = 0.1,0.3, 0.9, 2.7, 8.1
(b) The Explicit Rule for f(n) is 100 × 0.1ⁿ, The Recursive Rule for f(n) is f(n-1) x 0.1
Given,
n= 0,1,2,3,4..
f(n) = 100, 10, 1,0.1, 0.01
The explicit formula is the formula to calculate the value of the sequence directly without using any previous terms. The recursive formula uses the previous term to calculate the value of the current term.
In this example, the explicit formula is 100 × 0.1ⁿ and the recursive formula is f(n) = f(n-1) × 0.1. This means that each term in the sequence is equal to the previous term multiplied by 0.1.
For example, the third term in the sequence is 1, so the fourth term is 1 × 0.1 = 0.1.
(c) The Explicit rule for f(n) is 1000 × 0.1⁽ⁿ ⁻ ¹⁾, The Recursive rule for f(n) is f(n-1) x 0.1
To solve,
f(5) = 1000 × 0.1⁽⁵ ⁻ ¹⁾(5-1)
= 1000 × 0.1⁴
= 1000 × 0.0001
= 0.1
Given,
n= 1,2,3,4,5…
f(n) = 1000, 100, 10, 1, 0.1
The explicit and recursive rules for this geometric sequence are both written as f(n) = 1000 × 0.1⁽ⁿ ⁻ ¹⁾. This means that the value of the sequence at any given point n will be equal to 1000 multiplied by 0.1 raised to the power of n-1. This means that the value of the sequence decreases by a factor of 0.1 for every increase in n.
In this case,
f(5) = 1000 x [tex]0.1^4[/tex]
= 0.1.
(d) The Explicit Rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence.
The Recursive Rule for this geometric sequence is f(n) = f(n-1) ÷ 10³, where f(n) is the value for the nth term of the sequence and f(n-1) is the value for the (n-1)th term of the sequence.
Given,
n= 1,2,3,4,5..
f(n) = 10⁵⁰,10⁴⁷, 10⁴⁴, 10⁴¹, 10³⁸….
The value for the 5th term of the sequence is f(5) = 10⁽⁵⁰ ⁻ ³⁽⁵⁾⁾ = 10³⁸. The explicit rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence. This means that the value of each term is determined by taking 10 to the power of 50 minus 3 multiplied by the term number.
The recursive rule for this geometric sequence is [tex]\frac{f(n-1)}{10^3}[/tex] which means that the value of each term can be calculated by dividing the previous term by 10 cubes. We can use

What is profit and loss?
A profit and loss (P&L) statement could be a monetary report that has a outline of a company’s revenue, expenses and profit. It provides investors and alternative interested parties an insight into however an organization is working and whether or not it's the flexibility to get a profit.
Main Body:
Estimated total overhead costs = $456,000
Estimated direct labor costs = $2,280,000
Actual overhead costs= $422,000
Actual direct labor costs= $1,940,000
To calculate the factory overhead, we need to first calculate Estimated overhead rate.
Estimated overhead rate = Estimated total overhead costs / Estimated direct labor costs
= $456,000 / $2,280,000
= 0.2
= 20%
Therefore;
Actual Factory overhead = Actual direct labor cost × application rate
= $1,940,000 × 20%
= $388,000
We can get the balance in the overhead account as shown below;
Balance = Actual overhead cost - Actual cost that should be applied
= $422,000 - $388,000
= $34,000 (Debit).
Hence there is debit of $34000.

9. Delia bought $45 dollars worth of clothes, but the total including sales tax came to $54. What is
the sales tax rate that Delia paid?
of the vehicles
Answer:
20%
Step-by-step explanation:
You want to know the tax rate if the added tax brings the cost of $45 purchase to a total of $54.
MultiplierThe multiplier applied to a purchase cost to add the tax is ...
(1 +r)
where r is the tax rate.
Here, that means ...
45(1 +r) = 54
1 +r = 54/45 = 1.20
r = 1.20 -1 = 0.20 = 20%
The tax rate Delia paid on the articles she bought was 20%.
there is a line that includes the point 9,7 and has a slope of 1. what is its equation in slope intercept form?
Step-by-step explanation:
Note that the slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
Plug in the slope for m and the given coordinate for x and y:
9 = (7)(2) + b
9 = 14 + b
b = -5
y = 7x - 5
Tyshawn took a taxi from his house to the airport. The taxi company charged a pick-up fee of $2.50 plus $3.50 per mile. The total fare was $79.50, not including the tip. Which equation could be used to determine mm, the number of miles in the taxi ride?
Answer: m = 22
Step-by-step explanation:
First, you subtract $2.50 from the total of $79.50 (because that is the static fee) to get $77.00. Now, because every mile is $3.50 and we want to find the number of miles, we divide $77 by $3.50 to get 22. (An easy way to do this mentally is to divide 77 by 7 and multiply by 2.) Therefore, m = 22.

roses, 36 carnations, and 54 tulips. How
many equal-sized bouquets can be made
using all of the flowers if the florists make
sure that each bouquet has the same
number of each type of flower?
The number of banquets that can be formed is 6 and total number of flowers are 2+3=5.
What is the greatest common divisor?
the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, and y.
We have given,
Petal and Leaf florists currently have 30 roses, 36 carnations, and 54 tulips
Since it is given that there are 75 rose and 45 lily flowers. Therefore,
Factorise 30 as follows:
30 = 2 × 3 × 5
Factorise 36 as follows:
36 = 2 × 2 × 3 × 3
Factorise 54 as follows:
54 = 2 × 3 × 3 × 3
We know that HCF is the highest common factor.
Since the common factor between the numbers 30, 36, and 54 is 2×3=6.
Hence, the number of banquets that can be formed is 6 and total number of flowers are 2+3=5.

Given: C is the midpoint of DA and FE bisects LAED. List three congruence statements and reasons based on
the given information.
Triangles ΔAEC, ΔECD are congruent.
What are conditions of Congruency?Three angles and three sides, or the six measuring components, specify the requirements for the congruence of triangles. But if three of these are correctly satisfied, the other three are also satisfied automatically. Axioms for congruency are four such instances.
Triangles are said to be congruent if:
Congruent triangles under the SSS (Side Side Side postulate) condition.
Congruent triangles criterion according to the SAS (Side Angle Side postulate).
Congruent triangles are a requirement of the ASA (Angle Side Angle postulate).
The congruent triangles criterion of the AAS (Angle Angle Side postulate).
Given C is mid point of AD.
and, FE bisects the angle ∠AED.
By SAS Postulate we can say ΔAEC, ΔECD are congruent.
In triangles ΔAEC, ΔECD;
AC=CD (C is mid point)(S);
∠CEA=∠CED (Bisector)(A)
CE=CE (Common side)(S);
So by SAS theorem both are Congruent.
