which of the following equations are linear? a. y = 6x 8 b. y 7 = 3x c. y – x = 8x 2 d. 4y = 8
A linear equation is an equation in which the highest power of an unknown quantity is 1. Among the given options, the equation y = 6x + 8 is linear.
Hence, the correct option is a. y = 6x + 8.
An equation is linear if and only if it can be written in the form y = mx + c, where m and c are real numbers. In the given options, the equation y = 6x + 8 can be written in the form y = mx + c where m = 6 and c = 8, so it is linear. On the other hand, the equation y – x = 8x2 can be rearranged to give y = 8x2 + x, so the highest power of x is 2. Hence, this equation is not linear.Similarly, the equation 4y = 8 can be rearranged to give y = 2, which is a constant, and so it is also not linear.Finally, the equation y7 = 3x is not linear because the exponent 7 on y is greater than 1 and makes the equation non-linear. Therefore, the correct answer is option a. y = 6x + 8.

Hope it is helpful....(a) Calculate sinh (log(6) - log(5)) exactly, i.e. without using a calculator Answer: (b) Calculate sin(arccos(76)) exactly, i.e. without using a calculator.
(a) The exact value of sinh(log(6) - log(5)) is 11/60.
To calculate sinh(log(6) - log(5)), we can use the identity: sinh(x) = ([tex]a^n[/tex] - [tex]e^-x[/tex])/2
So, substituting x = log(6) - log(5), we get:
sinh(log(6) - log(5)) = ([tex]e^(log(6)[/tex] - log(5)) - [tex]e^-(log(6)[/tex] - log(5)))/2
= (([tex]e^log(6)[/tex])/([tex]e^log(5)[/tex]) - ([tex]e^-log(6)[/tex])/([tex]e^-log(5)[/tex]))/2
= ((6/5) - (5/6))/2
= (36/30 - 25/30)/2
= 11/60
Therefore, sinh(log(6) - log(5)) = 11/60.
(b) The exact value of sin(arccos(76)) is undefined.
To calculate sin(arccos(76)) exactly, we can use the Pythagorean identity [tex]sin^2[/tex](x) + [tex]cos^2[/tex](x) = 1.
Let's assume arccos(76) = x. Applying the cosine function to both sides, we have cos(arccos(76)) = cos(x).
Since arccos and cosine are inverse functions, cos(arccos(76)) simplifies to 76.
Now, using the Pythagorean identity, we can calculate sin(x):
sin(x) = sqrt(1 - [tex]cos^2[/tex](x)) = sqrt(1 - 76^2) = sqrt(1 - 5776) = sqrt(-5775).
The square root of -5775 is an imaginary number, which cannot be expressed exactly without using complex numbers or numerical methods.
Therefore, the exact value of sin(arccos(76)) cannot be determined without using a calculator or numerical methods.

the price of a jacket was reduced from $50 to $30. by what percentage was the price of the jacket reduced?
Answer:
the jacket price was reduced by 40%.
Step-by-step explanation:
if $50 is 100% then every one dollar is 2%.
Percentage of the reduction of price of the jacket is 40%.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100.
Percentage is usually denoted by the symbol '%'.
We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Given that,
Original price of the jacket = $50
Let x be the percentage of reduction of the price of the jacket.
50 - (x × 50) = 30
50x = 50 - 30
50x = 20
x = 20 / 50
x = 0.4
Percentage = 0.4 × 100 = 40%
Hence the percentage reduction is 40%.

Using the Ratio Test the series ∑(n³ / [tex]4^n[/tex]) converges. Option A is the correct answer.
To determine the convergence or divergence of the series ∑(n³ / [tex]4^n[/tex]), we can apply the Ratio Test.
The Ratio Test states that if the limit of the absolute value of the ratio of consecutive terms in a series is less than 1, then the series converges. If the limit is greater than 1 or it does not exist, the series diverges.
Let's apply the Ratio Test to the given series:
lim n → ∞ |([tex]a_n[/tex] + 1) / [tex]a_n[/tex]| = lim n → ∞ |((n + 1)³ / [tex]4^{(n + 1)[/tex]) / (n³ / [tex]4^n[/tex])|
We simplify the expression by multiplying by the reciprocal:
lim n → ∞ |((n + 1)³ / [tex]4^{(n + 1)[/tex]) × ([tex]4^n[/tex] / n³)|
Next, we simplify the expression inside the absolute value:
lim n → ∞ |((n + 1)³ × [tex]4^n[/tex]) / ([tex]4^{(n + 1)[/tex] × n³)|
Now, we can cancel out the common factors:
lim n → ∞ |(n + 1)³ / (4 × n³)|
Simplifying further:
lim n → ∞ |(n + 1) / (4n)|³
Taking the limit as n approaches infinity:
lim n → ∞ |(1 + 1/n) / 4|³
Since the limit of the absolute value of the ratio is less than 1 (as n approaches infinity), the series converges.
Therefore, the answer is:
A. Converges

Value of y[1] = 0.5 and y[2] = 0.5.
The given discrete-time system is:
y[k-1] + 2y[k] = [k]with y(0) = 0.
Substituting k = 0 in the above equation:
y[-1] + 2y[0] = [0] y[-1] = 0
Substituting k = 1 in the given equation:
y[0] + 2y[1] = [1]
Substituting the value of y[0] from the above equation in this equation, we get:
2y[1] = [1] - y[0]
Substituting the value of y[0] = 0 in the above equation:
2y[1] = [1]y[1] = [1]/2 = 0.5
Substituting k = 2 in the given equation:
y[1] + 2y[2] = [2]
Substituting the value of y[1] from the above equation in this equation, we get:
2y[2] = [2] - y[1]
Substituting the value of y[1] = 0.5 in the above equation:
2y[2] = [2] - 0.5y[2] = [2]/2 - 0.5 = 0.5

Based on the given options, the additional information that could be used to prove congruence using AAS or ASA is:
Option 1: B ≅ P and BC ≅ PQ
To prove that two triangles are congruent using AAS (Angle-Angle-Side) or ASA (Angle-Side-Angle) postulates, we need specific conditions met. Let's examine the given options:
1. B ≅ P and BC ≅ PQ:
This condition satisfies the AAS postulate since we have two angles and a corresponding side that are congruent.
2. A ≅ T and AC = TQ = 3.2 cm:
This condition satisfies the ASA postulate since we have two angles and the included side that are congruent.
3. A ≅ T and B ≅ P:
This condition alone does not satisfy either the AAS or ASA postulate, as we need to have at least one side congruent or an included side congruent to prove congruence.
4. AC = TQ = 3.2 cm and CB = QP = 2.2 cm:
This condition alone does not satisfy either the AAS or ASA postulate, as we need to have congruent angles as well.

Find z1/z2 in polar form. The angle is in degrees. z1= 15 cis (83) and z2 = 6 cis (114).
To find the division of z1 by z2 in polar form, where the angles are given in degrees, we have z1 = 15 cis (83°) and z2 = 6 cis (114°). The polar form of the division of z1 by z2 is 2.5 cis (329°).
To divide complex numbers in polar form, we can divide their magnitudes and subtract their angles. Let's start by dividing the magnitudes:
|z1/z2| = |z1|/|z2| = 15/6 = 2.5
Next, we subtract the angles:
θ = θ1 - θ2 = 83° - 114° = -31°
Since the angle is negative, we add 360° to it to get a positive angle in the standard range:
θ = -31° + 360° = 329°
Therefore, the division of z1 by z2 in polar form is given by:
z1/z2 = 2.5 cis (329°)
So, the polar form of the division of z1 by z2 is 2.5 cis (329°).

Let C be a relation defined on R as follows: For all x,y∈R,xCy iff x 2 +y2 =1. Determine if C is reflexive, symmetric, transitive, or none of these.
The relation C is defined on the set of real numbers (R) as xCy if [tex]x^2[/tex] + [tex]y^2[/tex] = 1 is not reflexive, not symmetric, and not transitive.
To determine if the relation C is reflexive, we need to check if every element x in R is related to itself. However, for any real number x, [tex]x^2[/tex] + [tex]x^2[/tex] = 2[tex]x^2[/tex] ≠ 1. Therefore, C is not reflexive.
For symmetry, we need to check if whenever xCy, then yCx. However, if we take x = 0 and y = 1, we have [tex]x^2[/tex] + [tex]y^2[/tex] = [tex]0^2[/tex]+ [tex]1^2[/tex] = 1, which satisfies the condition for C. But for yCx, we have [tex]y^2[/tex] + [tex]x^2[/tex] = [tex]1^2[/tex] + [tex]0^2[/tex] = 1, which also satisfies the condition. Therefore, C is symmetric.
To test for transitivity, we need to check if whenever xCy and yCz, then xCz. However, if we consider x = 0, y = 1, and z = -1, we have [tex]x^2[/tex] +[tex]y^2[/tex] = [tex]0^2[/tex]+ [tex]1^2[/tex] = 1 and [tex]y^2[/tex] + [tex]z^2[/tex] =[tex]1^2[/tex] + [tex](-1)^2[/tex] = 2. Since 1 + 2 ≠ 1, the condition for transitivity is not satisfied. Thus, C is not transitive.
In conclusion, the relation C is not reflexive, symmetric, or transitive.
