Answer:
[tex] y' = -\dfrac{\cot x \csc x}{2 \sqrt{x}} [/tex]
Step-by-step explanation:
y = csc x
y' = -cot x csc x
[tex] y = \csc \sqrt{x} [/tex]
[tex] y' = \dfrac{d}{dx} [\csc \sqrt{x}] [/tex]
[tex]y' = (-\cot x \csc x) \dfrac{d}{dx} \sqrt{x}[/tex]
[tex]y' = (-\cot x \csc x) \dfrac{d}{dx} x^{\frac{1}{2}}[/tex]
[tex]y' = (-\cot x \csc x) \dfrac{1}{2} x^{-\frac{1}{2}}[/tex]
[tex] y' = -\dfrac{\cot x \csc x}{2 \sqrt{x}} [/tex]

Suppose 5,500 dollars is placed in a saving account how much money would be in the saving account after 5 years if the compound interest semiannually at a rate of 5% per year
Answer:
FV= $7,040.46
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,500
Number of periods (n)= 5*2= 10 semesters
Interest rate (i)= 0.05/2= 0.025
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1+i)^n
FV= 5,500*(1.025^10)
FV= $7,040.46

Ricky is solving a multiplication problem where both terms include decimal values. The first term has 4 digits after the decimal. The second term has 5 digits after the decimal. The product will have how many digits after the decimal?
Answer:
9 digits
Step-by-step explanation:
when doing multiplication with decimals the amount of digits after the decimal in the final product will be the sum of the amounts of digits after the decimal in the two numbers being multiplied together
For example, If you were to multiply 6.789 by 10.321 the answer would be 70.069269. There are six digits after the decimal because the numbers being multiplied each have three digits after their decimals
(If that makes sense. If not, I'm sorry)

What is the inverse function F(x)=-1/2(x+3)?
The inverse of the function f(x) is
[tex]f^{-1}[/tex] (x) = 2x - 3
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 1/2 (x + 3)
Put f(x) = y
y = 1/2 (x + 3)
Replace y and x.
x = 1/2 (y + 3)
Find y.
2x = y + 3
y = 2x - 3
This means,
[tex]f^{-1}[/tex] (x) = 2x - 3
Thus,
The inverse of f(x) is 2x - 3.

An airport shuttle service charges $15 plus $1.15 per mile. An equation is written as y=mx+b, where y is the cost for x miles.
Answer: See explanation
Step-by-step explanation:
You didn't really say what you need to calculate but let me try to help out.
From the question, we are informed that an airport shuttle service charges $15 plus $1.15 per mile and that an equation is written as y=mx+b, where y is the cost for x miles.
The equation can be expressed as:
y = 15 + 1.15x
where,
15 = y intercept and this is the initial fixed cost
1.15 = slope and this is the cost per mile
x = number of miles
What is the volume of a cylinder with a radius of 1.5 inches and a height of 19 inches? Use 3.14 for pi. Round your answer to the nearest hundredth.
Answer:
134.24 in³
Step-by-step explanation:
Use the formula for the volume of a cylinder, V = [tex]\pi[/tex]r²h
Plug in the radius, pi, and the height:
V = [tex]\pi[/tex]r²h
V = (3.14)(1.5²)(19)
V = 134.235
= 134.24 in³
So, the volume of the cylinder is 134.24 in³
Answer:
134.24 in³

After Thanksgiving, Fernando had 3/8 of a pumpkin pie left. Later that night, 1 point
Fernando ate 2/3 of the remaining pie. How much of the pumpkin pie did
Fernando eat?*
3/8 of the pie
9/16 of the pie
1/4 of the pie
06/24 of the pie
Answer:
(C) 1/4 of the pie.
Step-by-step explanation:
Given that Fernando had 3/8 of a pumpkin pie left.
So, the remaining pie= 3/8 of a pie.
As Fernando ate 2/3 of the remaining pie, so,
the portion of a pie that Fernando ate = 2/3 x 3/8 of a pie = 1/4 of a pie.
So, Fernando ate 1/4 of a pie.
Hence, option (C) is correct.

Olivia needs 54 ticks for every 3 lollipops she eats. Complete the table using equivalent ratios. Lollipops
Answer:
36:2
90:5
Step-by-step explanation:
I got 2 because if we figure out how many licks she gets for every 1 lollipop that will help find the other numbers. When we divide 54 by 3 we get 18. For every 1 lollipop she lickes 18 times. To figure out how many lollipops for 36 I added 18 plus 18 which gives me 36. I added it twice or multiples by 2. Since I multiplied by 2 the lollipops will be 2. Since we know the rate of change which is 18. We know that for 3 lollipops the person will lick 54 times. I added 54 plus 18 two times which gave me 90. So for 90 licks the person will have 5 lollipops. I hope this helps.

The new post office has an area that is 6.5 times the area of the old post office. Let p represent the area of the old post office. Write an expression to represent the area of the new post office?
Answer:
[tex]Area = 6.5p[/tex]
Step-by-step explanation:
Given
[tex]Area\ of\ Old = p[/tex]
[tex]Area\ of\ New = 6.5 * Area\ of\ Old[/tex]
Required
Write an expression for the area of new post office
From the question, we have the following:
[tex]Area\ of\ Old = p[/tex]
and
[tex]Area\ of\ New = 6.5 * Area\ of\ Old[/tex]
Substitute p for Area of Old in the second equation
[tex]Area\ of\ New = 6.5 * p[/tex]
[tex]Area\ of\ New = 6.5 p[/tex]
Hence, the expression is:
[tex]Area = 6.5p[/tex]
