Hiw many degrees is it?
Answers
Answer:
Step-by-step explanation:
If the value of x is what you need then you can work that out by doing the following:
3x + 3
Isolate 3x by taking 3 off both sides:
3x = -3
Divide both sides by 3 to get the value of x:
x = -1

What is the absolute value of 2 - 9i ?
Help me out
Answers
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Absolute value.
so we get as,
let, y = 2 - 9i
so the absolute value is |y|
[tex] |y| = \sqrt{ {2}^{2} + {9}^{2} } [/tex]
so we get as,
|y| =
[tex] \sqrt{81 + 4} = \sqrt{85} [/tex]
so the absolute value is

You measure 41 textbooks' weights, and find they have a mean weight of 30 ounces. Assume the population standard deviation is 12.3 ounces. Based on this, construct a 93% confidence interval for the true population mean textbook weight. Round z-values to 2 decimal places; round t-values to 3 decimal places. Round final answers to 2 decimal places.
Answers
Answer:
The 93% confidence interval is [tex] 26.52 < \mu < 33.48 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 41
The mean is [tex]\= x = 30[/tex]
The standard deviation is [tex]\sigma = 12.3[/tex]
From the question we are told the confidence level is 93% , hence the level of significance is
[tex]\alpha = (100 - 93 ) \%[/tex]
=> [tex]\alpha = 0.07[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.81[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 1.812 * \frac{12.3}{\sqrt{41} }[/tex]
=> [tex]E = 3.48 [/tex]
Generally 93% confidence interval is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
=> [tex] 30 -3.48 < \mu < 30 + 3.48 [/tex]
=> [tex] 26.52 < \mu < 33.48 [/tex]

65,000 (Cost) – 5,000 (Salvage Value) ÷ 60 (5 years X 12 months per year) = 1,000 in depreciation per month.
a) Accumulated depreciation from 1/1/12 to 1/1/15 is 36,000 (12 months for 2012, 2013, & 2014).

b) Accumulated depreciation from 1/1/12 to 5/1/15 is 40,000 (12 months for 2012, 2013, 2014, & 4 months for 2015).
Assuming that sale was a Cash sale, the journal entry would look like this:

Find the Derivative.
f(x) = -xcos3x
Answers
Answer:
[tex]\frac{d}{dx}(-xcos3x)= 3x \ sin(3x)- cos(3x)[/tex]
Step-by-step explanation:
Use the Product Rule for derivatives, which states that:
[tex]\frac{d}{dx} =[f(x)g(x)]= f(x)g'(x)+f'(x)g(x)[/tex]In the function we are given, [tex]f(x)=-x \cos3x[/tex], we can break it up into two factors: -x is being multiplied by cos3x.
Now, we have the factors:
[tex]-x \\ $cos 3x[/tex]Before using the product rule, let's find the derivative of cos3x using the chain rule and the power rule.
[tex]\frac{d}{dx}(cos3x)= \frac{d}{dx} (cos3x) \times \frac{d}{dx} (3x) \\ \frac{d}{dx}(cos3x)= (-sin3x) \times 3 \\ \frac{d}{dx} (cos3x) = -3sin(3x)[/tex]Now let's apply the product rule to f(x) = -xcos3x.
[tex]\frac{d}{dx}(-xcos3x)= (-x)(-3sin3x) + (-1)(cos3x)[/tex]Simplify this equation.
[tex]\frac{d}{dx}(-xcos3x)= (x)(3sin3x) - (cos3x)[/tex]Multiply x and 3 together and remove the parentheses.
[tex]\frac{d}{dx}(-xcos3x)= 3x \ sin(3x)- cos(3x)[/tex]Therefore, this is the derivative of the function [tex]f(x)=-xcos3x[/tex].
Hi there!
[tex]\large\boxed{f'(x) = -cos3x + 3xsin3x}[/tex]
[tex]f(x) = -xcox3x\\\\\text{Use the product rule and chain rule to solve for the derivative:}\\\\\frac{dy}{dx}= -cos3x + (-x * (-sin3x) * 3)\\\\= -cos3x + 3xsin3x[/tex]

slope = -2
y intercept = 6
=====================================================
Explanation:
Let's find the slope
m = (y2-y1)/(x2-x1)
m = (2-4)/(2-1)
m = -2/1
m = -2
The slope is -2
Let's use this slope along with the first point to get the y intercept
y = mx+b
y = -2x+b ... plug in the slope we found earlier
4 = -2*1+b ... plug in the coordinates of the point (1,4)
4 = -2+b
4+2 = -2+b+2 .... adding 2 to both sides
6 = b
b = 6
The y intercept is 6
The equation y = mx+b turns into y = -2x+6 since m = -2 is the slope and b = 6 is the y intercept.
The school that Adam goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 5 senior citizen tickets and 15 student tickets for a total of $137.50. The school took in $430 on the second day by selling 20 senior citizen tickets and 44 student tickets. Find the price of a student ticket.
Answers
Answer:
Let the price of one senior citizen ticket be sc and the price of one student ticket be st.
Let's write equations using the information given and the variables above:
=> 5sc + 15st = $137.50
=> 20sc + 44st = $430
Hmm.. We can multiply 5sc by 4 to get 20sc.
=> 4(5sc) + 4(15st) = 4($137.50)
=> 20sc + 60st = $550
Now we can subtract the second equation from the first to determine the price of a student ticket.
20sc + 60st = $550
- 20sc + 44st = $430
=> 16st = $120
=> st = $7.5
So, the price of a student ticket is $7.5.

The Grand Canyon Skywalk at Eagle Point is a horseshoe shaped steel frame with a glass floor looking down to the Grand Canyon below. The Skywalk extends 70 feet over the canyon rim and is 10 feet wide. The walkway consists of a semicircle with a straight portion on each side as indicated in the diagram below. How many square feet of glass are needed to cover the Skywalk floor? (Round your final answer to 1 decimal place and any intermediate calculations to 2 decimal places. Be sure to include units.)
Answers
Answer: It will be needed 864 square feet of glass to cover the Skywalk floor.
Step-by-step explanation: The figure below shows the area in question.
Area of a circle is given by
[tex]A=\pi.r^{2}[/tex]
The walkway is a semicircle. Then, area will be:
[tex]A=\frac{\pi.r^{2}}{2}[/tex]
The area that will be covered with glass is the area between the outer and the inner circles. So, area is
[tex]A_{t}=A_{outer}-A_{inner}[/tex]
[tex]A_{t}=\frac{\pi.r_{o}^{2}}{2}- \frac{\pi.r_{i}^{2}}{2}[/tex]
[tex]A_{t}=\frac{\pi}{2}(32.5^{2}-22.5^{2})[/tex]
[tex]A_{t}=\frac{\pi}{2}(550)[/tex]
[tex]A_{t}=[/tex] 864
To cover the Skywalk floor is needed 864[tex]ft^{2}[/tex] of glass.

Input is the number in the first column of the table. This is the number that you start with to follow the rule if the rule is given. You would also use this number to figure out what the rule is if it is not given.

An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (\begin{align*}x\end{align*}-value) by 3 to find each output number (\begin{align*}y\end{align*}-value).
