Answer:
x = $25,400 [the original price of the Junko car]
Step-by-step explanation:
The price Ben paid, $23,622, is after the 7% discount. Let x be the original price of the Jinko car. Ben's prices reflect a 7% discount:
x*(1-0.07) = $23,622 [The expression (1-0.07) means the original price, 1, is reduced by 7%, -0.07, to give the final price]
(0.93)x = $23,622
x = $25,400
What is true about the complex number -5 - 5i? A. The modulus is 5√2. B. It lies in quadrant 3. C. The modulus is 5. D. It lies in quadrant 2.
Answer:
A. The modulus is 5√2.
B. It lies in quadrant 3
Step-by-step explanation:
Given a complex value z = x = iy
The modulus is expressed as;
|z| = √x²+y²
Given the complex number z = -5 - 5i
|z| = √(-5)²+(-5)²
|z| = √25+25
|z| = √50
|z| = √25 * √2
|z| = 5√2
For the argument;
theta = arctan(-5/-5)
theta = arctan 1
theta = 45degrees
since tan is positive in the third quadrant, hence it lies in quadrant 3
help! determine the equation of the circle graphed below:
The equation of a circle is (x+3)² + (y+5)² = 4² with a center at (-3,-5).
What is the equation of a circle?The equation of a circle with center (h,k) and radius r is :
r² = (x−h)² + (y−k)²
The center is approximated to lie at the position (-3,-5) in the graph below with the axes of symmetry. The points of intersection of the circle with any of the two axes (broken lines) provide a diameter of around 8 units, and so the radius is half the diameter, which is 4 units.
The equation of the circle whose graph is given below is:

Answer:

Step-by-step explanation:
5t^2-(3-6t-8t^2)
=5t^2-3+6t+8t^2
=13t2-3+6t
Answer:
[tex]\boxed {\boxed {\sf B. \ 13t^{2} -3+6t}}[/tex]
Step-by-step explanation:
We are given this expression and asked to simplify:
[tex]5t^2-(3-6t-8t^2)[/tex]
First, distribute the -1. Multiply each term in the parentheses by -1 or switch the sign of every term inside the parentheses.
[tex]5t^2+ (-1*3)+(-1*-6t)+(-1*-8t^2)[/tex]
[tex]5t^2+(-3)+(6t)+(8t^2)[/tex]
[tex]5t^2-3+6t+8t^2[/tex]
Next, combine like terms. We see that two terms have a t², so they are like terms. We can add them together.
[tex](5t^2+8t^2)-3+6t[/tex]
[tex]13t^2-3+6t[/tex]
The simplified expression is 13t²-3+6t and Choice B is correct.
At a restaurant, Asanji and his three friends decided to divide the bill evenly. If each person paid $20, then what was the total?
Answer:
The answer will bee 6.6666666667 well with nine zeros
Why should u subtract 9 from both sides of the equation:
K+9=-43
Subtracting from both sides leaves you with . Since subtraction can be written as addition (adding the opposite), the addition property of equality. If two expressions are equal to each other and you add the same value to both sides of the equation, the equation will remain equal.
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. ... Performing the same operation on both sides of an equation does not change the validity of the equation, or the value of the variable that satisfies it.

How do you find the sides of a triangle with only the angles?
The Sides of triangle when only the angles of triangles are given can be found by using the Law Of Sines .
What is Law Of Sines ?
The Law Of Sines states that the ratio of sides of a triangle and their respective Sine angles are equivalent to each other. The other names by which the law of sines is known are Sine Law, Sine Rule and Sine Formula.
The Sine Law is used to find unknown side of an oblique triangle. The oblique triangle is defined as a triangle that is not a right triangle.
Let a , b and c be the sides of a triangle ABC , and A , B and C be the angles .
So , by Sine Law : [tex]\frac{a}{SinA}=\frac{b}{SinB}=\frac{c}{SinC}[/tex] ;
Therefore , The Law Of Sines help in finding the sides of triangle that has only angles .

The Constraints of the inequality are
x ≤ 2y + 500
22500 < √ 35x + 50y
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
The Company A (x) at most 500 more than twice then unit by B(y).
So, x ≤ 2y + 500
Now, the square of Company Profit will be equal to 35x + 50y
Then, the constraints will be
1. x ≤ 2y + 500
2. Company Profit² < 35x + 50y
Company Profit < √ 35x + 50y

what is the leading coefficient of this polynomial? y=5x² + 3x^6 -10x-8,
Explanation:
The equation y = 5x^2+3x^6-10x-8 is not in standard form.
Why not? Because the term with the largest exponent (6) isn't listed first.
The standard form would be y = 3x^6+5x^2-10x-8; note the exponents decrease (6, 2, 1, then 0).
After the polynomial is in standard form, we can read off the leading coefficient to be 3. This is the coefficient of the first term 3x^6.
Side note: The degree is 6 as it's the largest exponent.

The least common multiple of $1! 2!$, $2! 3!$, $3! 4!$, $4! 5!$, $5! 6!$, $6! 7!$, $7! 8!$, and $8! 9!$ can be expressed in the form $a\cdot b!$, where $a$ and $b$ are integers and $b$ is as large as possible. What is $a b$
By solving the given factorial question we get a+b=2538.
How does factorial work?In mathematics, the term "factorial" refers to the sum of all positive integers that are less than or equal to a specific positive integer, which is followed by an exclamation point. Thus, factorial seven is denoted by the symbol 7!, which stands for 1 2 3 4 5 6 7. Factorial 0 is equal to 1 by definition.
Solution:-
We can factor each of these numbers.1! + 2! = 1! ( 1 + 2 )
2! + 3! = 2! ( 1+ 3 )
3! + 4! = 3! ( 1 + 4 )
4! + 5! = 4! ( 1 + 5 )
5! + 6! = 5! ( 1 + 6 )
6! + 7! = 6! ( 1 + 7 )
7! + 8! = 7! ( 1 + 8 )
8! + 9! = 8! ( 1 + 9 )
Once again:
1! + 2! = 1! ( 3 )
2! + 3! = 2! ( 4 )
3! + 4! = 3! ( 5 )
4! + 5! = 4! ( 6 )
5! + 6! = 5! ( 7 )
6! + 7! = 6! ( 8 )
7! + 8! = 7! ( 9 )
8! + 9! = 8! ( 10 )
We can split the number into two parts, a! * bThe LCM of 1!, 2!, 3!, ... , 8! is 8!
The LCM of 3, 4, 5, ... , 10 is 2520
The LCM is 2520 * 8!
a = 2520
b = 8
a + b = 2528
