perpendicular to 8x - 2y = 5.
Answers
Step-by-step explanation:
First consider the given line 8x = 2y - 5. This can be rewritten as
2y = 8x + 5
y = (8x + 5)/2 = 4x + 2.5
The line is y = 4x + 2.5. This is of the form y = mx + b.
On comparing, we see that the slope of the given line is m = 4
Now, we require to find the slope of a line perpendicular to this. Let its slope be m'.
We know that for two lines to be perpendicular, the product of the slopes = -1
So, m * m' = -1
4 * m' = -1
m' = -1/4
Answer: Slope of the perpendicular line is -1/4.

C. Both

Answers
Answer:
A. Only A
Step-by-step explanation:
Lets take a look at Sequence A first. By translating triangle MNO along line segment NB, MNO's top left corner is now on point B, but the shape and orientation have not changed. Then, when we reflect MNO over the vertical line that goes through B, we "flip" MNO onto ABC exactly.
So Sequence A DOES map MNO onto ABC
Now let's take a look at Sequence B to see if it works too. First, we reflect, or "flip" triangle MNO over the vertical line that passes through points M and O. Now MNO and ABC have the same orientation or shape, but aren't in the same location. Next, Sequence B tells us to translate MNO along line segment MB. This puts point M on point B, resulting in the two triangles next to each other and in the same orientation, touching at point B, but not mapped onto one another.
So the answer is choice A: Only A maps MNO onto ABC

Answer:
Step-by-step explanation:
(d). Use an appropriate technique to find the derivative of the following functions:
(i) y = √4+3x²/ (x² +1)¹/³ . Pie^x
(ii) xy^3/1+ sec y= e^xy
[Verify your answer by MATHEMATICA and attach the printout of the commands and output]
Answers
(i) I would first suggest writing this function as a product of the functions,
[tex]\displaystyle y = fgh = (4+3x^2)^{1/2} (x^2+1)^{-1/3} \pi^x[/tex]
then apply the product rule. Hopefully it's clear which function each of f, g, and h refer to.
We then have, using the power and chain rules,
[tex]\displaystyle \frac{df}{dx} = \frac12 (4+3x^2)^{-1/2} \cdot 6x = \frac{3x}{(4+3x^2)^{1/2}}[/tex]
[tex]\displaystyle \frac{dg}{dx} = -\frac13 (x^2+1)^{-4/3} \cdot 2x = -\frac{2x}{3(x^2+1)^{4/3}}[/tex]
For the third function, we first rewrite in terms of the logarithmic and the exponential functions,
[tex]h = \pi^x = e^{\ln(\pi^x)} = e^{\ln(\pi)x}[/tex]
Then by the chain rule,
[tex]\displaystyle \frac{dh}{dx} = e^{\ln(\pi)x} \cdot \ln(\pi) = \ln(\pi) \pi^x[/tex]
By the product rule, we have
[tex]\displaystyle \frac{dy}{dx} = \frac{df}{dx}gh + f\frac{dg}{dx}h + fg\frac{dh}{dx}[/tex]
[tex]\displaystyle \frac{dy}{dx} = \frac{3x}{(4+3x^2)^{1/2}} (x^2+1)^{-1/3} \pi^x - (4+3x^2)^{1/2} \frac{2x}{3(x^2+1)^{4/3}} \pi^x + (4+3x^2)^{1/2} (x^2+1)^{-1/3} \ln(\pi) \pi^x[/tex]
[tex]\displaystyle \frac{dy}{dx} = \frac{3x}{(4+3x^2)^{1/2}} \frac{1}{(x^2+1)^{1/3}} \pi^x - (4+3x^2)^{1/2} \frac{2x}{3(x^2+1)^{4/3}} \pi^x + (4+3x^2)^{1/2} \frac{1}{ (x^2+1)^{1/3}} \ln(\pi) \pi^x[/tex]
[tex]\displaystyle \frac{dy}{dx} = \boxed{\frac{\pi^x}{(4+3x^2)^{1/2} (x^2+1)^{1/3}} \left( 3x - \frac{2x(4+3x^2)}{3(x^2+1)} + (4+3x^2)\ln(\pi)\right)}[/tex]
You could simplify this further if you like.
In Mathematica, you can confirm this by running
D[(4+3x^2)^(1/2) (x^2+1)^(-1/3) Pi^x, x]
The immediate result likely won't match up with what we found earlier, so you could try getting a result that more closely resembles it by following up with Simplify or FullSimplify, as in
FullSimplify[%]
(% refers to the last output)
If it still doesn't match, you can try running
Reduce[<our result> == %, {}]
and if our answer is indeed correct, this will return True. (I don't have access to M at the moment, so I can't check for myself.)
(ii) Given
[tex]\displaystyle \frac{xy^3}{1+\sec(y)} = e^{xy}[/tex]
differentiating both sides with respect to x by the quotient and chain rules, taking y = y(x), gives
[tex]\displaystyle \frac{(1+\sec(y))\left(y^3+3xy^2 \frac{dy}{dx}\right) - xy^3\sec(y)\tan(y) \frac{dy}{dx}}{(1+\sec(y))^2} = e^{xy} \left(y + x\frac{dy}{dx}\right)[/tex]
[tex]\displaystyle \frac{y^3(1+\sec(y)) + 3xy^2(1+\sec(y)) \frac{dy}{dx} - xy^3\sec(y)\tan(y) \frac{dy}{dx}}{(1+\sec(y))^2} = ye^{xy} + xe^{xy}\frac{dy}{dx}[/tex]
[tex]\displaystyle \frac{y^3}{1+\sec(y)} + \frac{3xy^2}{1+\sec(y)} \frac{dy}{dx} - \frac{xy^3\sec(y)\tan(y)}{(1+\sec(y))^2} \frac{dy}{dx} = ye^{xy} + xe^{xy}\frac{dy}{dx}[/tex]
[tex]\displaystyle \left(\frac{3xy^2}{1+\sec(y)} - \frac{xy^3\sec(y)\tan(y)}{(1+\sec(y))^2} - xe^{xy}\right) \frac{dy}{dx}= ye^{xy} - \frac{y^3}{1+\sec(y)}[/tex]
[tex]\displaystyle \frac{dy}{dx}= \frac{ye^{xy} - \frac{y^3}{1+\sec(y)}}{\frac{3xy^2}{1+\sec(y)} - \frac{xy^3\sec(y)\tan(y)}{(1+\sec(y))^2} - xe^{xy}}[/tex]
which could be simplified further if you wish.
In M, off the top of my head I would suggest verifying this solution by
Solve[D[x*y[x]^3/(1 + Sec[y[x]]) == E^(x*y[x]), x], y'[x]]
but I'm not entirely sure that will work. If you're using version 12 or older (you can check by running $Version), you can use a ResourceFunction,
ResourceFunction["ImplicitD"][<our equation>, x]
but I'm not completely confident that I have the right syntax, so you might want to consult the documentation.

y = 3/2x - 10
Step-by-step explanation:
The equation :
y - y1 = m(x - x1)

y = 3/2x - 12 + 2

Answers
Answer:
faye
Step-by-step explanation:
okay so
114-30=84
25% of 84 = 21
21 is how much elena has
21 x 2 = 42
42 is how much karla has
21 + 30 = 51
51 is how much faye has
42 + 21 = 63
63 + 51 = 114
so therefore faye has the most
How many different four-digit numbers can be formed with the numbers 7; 4; 5; 1; 2; 9; and 8?
Answers
One is with the repetition of digits.
The other is without repetition of digits.
ANSWER 1: With Repetition
Numbers: 1,2,4,5,7,8
There are 4 digits __ __ __ __
1st digit can be filled by any of the 6 numbers.
Similarly 2nd, 3rd and 4th digits.
Hence each digit will have 6 possibilities.
Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = 1296
ANSWER 2: Without Repetition
4 digits __ __ __ __
Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities
The second digit will have only 5 possibilities as one of the numbers gets used up by the 1st digit.
Similarly the 3rd and 4th digits will have 4 and 3 possibilities respectively.
Therefore no.of 4 digit numbers that can be formed are 6 x 5 x 4 x 3 = 360

What type of variable is N?
Binomial, geometric or neither?
Answers
Since the number of trials is not fixed, N is neither a binomial or a geometric variable, it is an inverse binomial variable.
The sample is chosen at random, hence, the trials are independent, that is, each person has the same probability of answering it, hence N is not a geometric variable.
For it to be a binomial distribution, there needs to be a fixed number of trials, which there is not, hence, N is also not a binomial variable.
The distribution that counts the number of trials until x successes in the inverse binomial distribution, which means that N is an inverse binomial variable.A similar problem is given at https://brainly.com/question/25644451
