12% profit on a computer is Rs.540.
(i) Find the cost price of the computer.
(ii) Find the sale price of the computer.
Answers
Answer:
the cost price is Rs. 4500 and the sale price is Rs. 5040.
Step-by-step explanation:
Let the cost price of the compute be Rs. x.
The profit earned is, Rs. 540.
The profit percentage is, 12%.
The formula to compute profit is:
Profit = SP - CP
\begin{gathered}540=x[1+\frac{12}{100}]-x\\540=1.12x-x\\540=0.12x\\x=\frac{540}{0.12}\\x=4500\end{gathered}540=x[1+10012]−x540=1.12x−x540=0.12xx=0.12540x=4500
Compute the selling price as follows:
SP = CP + profit
= 4500 + 540
= 5040
Thus, the cost price is Rs. 4500 and the sale price is Rs. 5040.

What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given equation is (2x - 1)(3x + 4) = 0
We have to find the solutions of the equation
As the equation is in factored form
We take each factor and solve for solution
2x-1=0
2x=1
Divide both sides by 2
x=1/2
Now 3x+4=0
3x=-4
Divide both sides by 3
x=-4/3
Hence, x=1/2 and x=-4/3 are the solutions of the equation (2x - 1)(3x + 4) = 0

I already finished A and B but I am stuck on the synthetic division part of the question. Thanks!
Answers
Answer:
a) positive real zeros: 2 or 0; negative real zeros: 2 or 0; complex zeros: 0, 2, or 4. (rule of signs)
b) ∪-shaped, as for an even-degree polynomial with positive leading coefficient. See attached.
c, d) See attached
Step-by-step explanation:
Descarte's rule of signs gives bounds on the number of positive and negative real roots. The numbers it gives may be reduced by multiples of 2, as complex roots will come in conjugate pairs. The total number of roots of all kinds will match the degree of the polynomial.
Synthetic division is essentially polynomial long division with some modifications:
the variables are omitted ("place value" is used instead)the constant in the divisor is negated so its product with the partial quotient can be added to obtain the new dividendthe divisor binomial is assumed to have a leading coefficient of 1.__
a)The signs of the terms of the given polynomial are + - - - +. There are two sign changes, so 2 possible positive real roots.
When the signs of the odd-degree terms are changed, the signs become + + - + +. There are still two sign changes, so 2 possible negative real roots.
Either or both of these numbers can be reduced by 2 if the roots include a conjugate pair. That is, there may also be 0 possible positive real roots, and 0 possible negative real roots.
The number of non-real (complex) zeros may be any multiple of 2 up to the degree of the polynomial. The may be 0, 2, or 4 possible non-real zeros.
__
b)The graph is the first attachment. It shows 4 real zeros: x = -4, -2, 1, 6.
Since the polynomial is of even degree (4) and has a positive leading coefficient (+1), we expect the general shape to be ∪-shaped. It is.
__
c)The second attachment shows synthetic division using x = -4. (The binomial divisor is (x+4).) The remainder (lower right value in the tableau) is the value of y when x=-4. The third attachment shows synthetic division using the value x=3. (y is -210 when x=3.)
Maybe this is the table you want:
[tex]\begin{array}{|c|c|c|}\cline{1-3}x&-4&3\\\cline{1-3}y&0&-210\\\cline{1-3}\end{array}[/tex]
__
d)The second attachment shows synthetic division by the factor (x+4).
_____
Additional comment
The synthetic division attachments show instructions for carrying out the synthetic division and interpreting the results. As we said above, "the entry on the left" is the opposite of the constant in the binomial divisor. It is the actual value of x you want to use to evaluate the function.
The equations shown are merely for the purpose of indicating the operations that are used. An actual synthetic division tableau is simply a 3-row table of numbers, with the bottom row being the quotient coefficients and remainder.

Method of treatment; Application of the chamomile oil to the cervical region of patients experiencing pain due to pinched nerves
Treatment assignment; Treatment should be assigned to patients with pinched nerves
Variables that should be measured; Reduction or relief of pain as reported by the patients
Part B; The study should be administered equally to both male and female as the symptoms can be experienced by both male and female

x + y + 70 = 180.y + 3x - 10 = 180 -> y = 190 - 3x.Then:
x + y + 70 = 180
x + 190 - 3x + 70 = 180.

The question was incomplete. Below you will find the missing content.
The square root function f(x) is x <= 7
Options are :
A. 7 is subtracted from the x-term inside the radical.
B. The radical is multiplied by a negative number.
C. 7 is added to the radical term.
D. The x-term inside the radical has a negative coefficient.
Option D is correct, which is : The x-term inside the radical has a negative coefficient.
Given, the domain of the square root function f(x) is x <= 7
Consider the function y = √x.
The domain of this function is x ≥ 0 and the range is y ≥ 0.
The expression inside the radical must be greater than or equal to zero.
Now, if x ≤ 7
x - 7 ≤ 0
7 - x ≥ 0
And the function y = √(7-x) will have the domain x ≤ 7.
This implies that the x-term inside the radical has a negative coefficient.
Therefore, the statement that the x-term inside the radical has a negative coefficient must be true.

Which statements accurately describe the function f(x) = 3(16) superscript three-fourths x? select three options.
Answers
Range for the given Exponential function [tex]f(x) = 3(16)^{{\frac{3}{4}x}[/tex] is f(x) > 0.
the correction option is a). f(x) > 0
The function given in, the question is exponential function is given by
[tex]f(x) = 3(16)^{{\frac{3}{4}x}[/tex] Which is an exponential function. The domain of the give function is (-∞, ∞).
The function which is in format f(x) = [tex]a^{x}[/tex] where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
the Question seems to be incomplete. And options could be
a) f(x) > 0 c) f(x) ≤ 0
b) f(x) < 0 d) f(x) ≥ 0
Simplification of the given equation
[tex]f(x) = 3(16)^{{\frac{3}{4}x}[/tex]
[tex]f(x) = 3(2^4)^{{\frac{3}{4}x}[/tex]
[tex]f(x) = 3(8)^{x}[/tex]
clearly, the range of the exponential function is f(x) > 0.

Step-by-step explanation:
Answer:
That would be $11.37
Step-by-step explanation:
First Multiply the discount and the original price

What is the slope in f(x)=6x+7
Answers
-------------------------------------------------------------------------------------------------------------
Answer: [tex]\textsf{Slope = 6}[/tex]
-------------------------------------------------------------------------------------------------------------
Given: [tex]\textsf{f(x) = 6x + 7}[/tex]
Find: [tex]\textsf{The slope of the equation}[/tex]
Solution: Looking at the equation it is in standard form which is y = mx + b where m is the slope and b is the y-intercept. Looking at our expression we can see that m is equal to 6 which is our slope.
Therefore, the slope of our expression is equal to 6.
