Find y'' if y= 9csc x
Answer:
y" = csc(x)[9cot²(x) - csc²(x)]
Step-by-step explanation:
Step 1: Define
y = 9csc(x)
Step 2: Find 1st derivative
y' = -9csc(x)cot(x)
Step 3: Find 2nd derivative
y" = 9csc(x)cot(x)cot(x) + -csc(x)csc²(x)
y" = 9csc(x)cot²(x) - csc³(x)
y" = csc(x)[9cot²(x) - csc²(x)]

The measures of the sides of an
equilateral triangle are (3x+6),
(9x-12), and (6x-3). Find x and the
measure of each side of the triangle.
Answer:
108 3833 832 i73336533
The value of x is 3 units and the measure of each side of the triangle is 15 units.
Given that, the measures of the sides of an equilateral triangle are (3x+6),
(9x-12) and (6x-3).
What is an equilateral triangle?An equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
Since, the sides of an equilateral triangle are, we get
3x+6=9x-12
⇒ 9x-3x=6+12
⇒ 6x=18
⇒ c=3
So, 3x+6 =9x-12 =6x-3 =15 units
Hence, the value of x is 3 units and the measure of each side of the triangle is 15 units.

Adding two functions results in h(x) = –x + 9, while multiplying the same functions results in j(x) = –9x.
Which statements describe f(x) and g(x), the original functions? Select two options.
A. Both functions must be quadratic.
B. Both functions must have a constant rate of change.
C. Both functions must have a y-intercept of 0.
D. The rate of change of either f(x) or g(x) must be 0.
E. The y-intercepts of f(x) and g(x) must be opposites.
Answer:
Both functions must have a constant rate of change.
The rate of change of either f(x) or g(x) must be 0.
From the first equation we know that both f (x) and g (x) must be of order 1 or of order 0, since the maximum exponent of X is 1. This indicates that both functions must have a constant rate of change , since the derivative of a function of order 0 or of order 1 is a constant.
From equation 2 we know that both f (x) and g (x) are composed of a single term, since the multiplication of both results in a single term (-9x). In addition, we verify that one of the functions is of order 0 and the other is of order 1, since the result of the product is of order 1.
If f (x) or g (x) are of order 0, which means that they are composed of only one constant, the rate of change of any of the 2 functions is 0.
Step-by-step explanation:
Answer:
B and D.
Step-by-step explanation:
We know that when we added the two functions together, we get:
[tex]h(x)=-x+9[/tex]
However, when we multiplied them together, we get:
[tex]j(x)=-9x[/tex]
Let's first consider what we can determine from this.
If we add them together, we get a linear equation. However, this doesn't mean that our two original functions are linear since if we have, say, -x^2 and x^2-x+9, they will cancel and form a linear equation if we add them together.
However, since we know that if we multiply the two functions together, we get a linear equation, this means that both our original functions must be linear.
But, if we multiplied two linear functions, then we should get a quadratic, since x times x will yield x².
Therefore, this means that one of our linear functions is a horizontal line with no x variable. This is the only way to have a linear equation when multiplied.
Therefore, we have determined that both of our original functions are linear functions, and one (only one of them) is a horizontal line.
Let's go through each of the answer choices.
A) Both functions must be quadratic.
This is false as we determined earlier. If this was true, then the resulting function should be a quartic and not a line. A is false.
B) Both functions must have a constant rate of change.
Remember that all linear equations have a constant rate of change.
Since we determined that both our original functions are linear equation, this means that both our functions will have a constant rate of change.
So, B is true.
C) Both functions must have a y-intercept of 0.
Remember that one of our functions is a horizontal line.
If the y-intercept was 0, then the equation of our horizontal line will be:
[tex]y=0[/tex]
And we know that anything multiplied by 0 will give us 0. However, the product of our function is -9x.
So, C cannot be true.
Rather, only our linear equation (not the horizontal line) may have a y-intercept of 0.
D) The rate of change of either f(x) or g(x) must be 0.
Remember that we determined that one of our lines must a horizontal.
Remember that horizontal lines have a slope of 0. In other words, the rate of change is 0.
So, D is true.
E) The y-intercepts of f(x) and g(x) must be opposites.
Well, since B and D is are true, this must be false since we can only select two options ;D
But, we can think about this. Note that if we multiply the two functions, we have a function without a y-intercept.
Remember that our horizontal line is not 0. So, the y-intercept of the horizontal line is a number.
So, the opposite of a number is another number.
So, if we multiply two non-zero numbers, we must get another number.
However, from our product, j(x)=-9x, we don't have another number. The y-intercept from this is 0.
Therefore, the two y-intercepts cannot be opposites of each other. If it was so, then we should have a y-intercept. So, E must be false.
In fact, this means that the y-intercept of our line (not the horizontal one) must be 0.
So, our answers are B and D.
And we're done!

A 6 pack of soda costs $2.40. A 12 pack of the same soda costs $5.40. Which is
the better deal? Explain your reasoning.
Answer:
The answer is that the 6 pack of is a way better deal.
Step-by-step explanation:
Answer:
The six pack for $2.40
Step-by-step explanation:
As we all know, 6 is half of 12. So then, if the deals were to be equal, the price for six would be half of the price for 12. So $2.40 + $2.40 should equal $5.40. It doesn't. It equals $4.80, which is less than $5.40, which means that it is the better deal because you could buy two six packs and get it cheaper than a twelve pack.

divide both sides by -5 to isolate w

A basketball player hit the basket eighteen times during the game. He scored a total of 30 points, two points for each field goal and one point for each free throw. If he threw 6 more field goals than free throws, how many field goals did he make? How many free throws did he make
-Pls provide work :)
Answer: He made 6 free throws and 12 field goals.
Step-by-step explanation:
Let x = Number of free throws
Then, Number of field goals = x+6
Number of times player hit the basket = 18
According to the question,
x+(x+6)=18
⇒ x+x+6=18
⇒ 2x+6=18
⇒ 2x=18-6
⇒ 2x=12
⇒ x=6 [Divide both sides by 2.]
So, he made 6 free throws and (6+6=) 12 field goals.
