Answer:
tan (θ+x)= -33/56
sin (θ+x)=33/65
Step-by-step explanation:
cosθ= -4/5 , sin x = -12/13
cosθ= -4/5; θ is in the third quadrant=> sinθ=-√(1-cos² θ)
sinθ=- √(1-16/25)=- √(9/25)=-3/5
sinx= -12/13; x is in the fourth quadrant=> cosx=+√(1-sin²x)
cosx=√(1-144/169)= √(25/169)=5/13
tgθ= sinθ/cosθ=(-3/5)/(-4/5)=3/4
tgx= sinx/cosx=(-12/13)/(5/13)= -12/5
tan (θ+x)=(tgθ+tgx)/(1-tgθ*tgx)
tan (θ+x)=(3/4-12/5)/(1+3/4*12/5)=(-33/20)/56/20)= -33/56
sin (θ+x)=sinθcosx+coxθsinx=-3/5 *5/13 +-4/5 * (-12/13)=-15/65+48/65=33/65
Were you surprised by the shape of your scatter plot? Explain.
Do you think there might be other factors that influence the association between the variables?
If you switched which axis each variable is graphed on, would your scatter plot look different? Describe and interpret the association between the variables.
Answer:
Answers are below
Step-by-step explanation:
Yes I was surprised by the scatter plot because I didn't know there would be the most rain at 77 degrees F on the red line.
If you switched which axis each variable is graphed on, your graph would look different because the graph could be sideways on the left or the right.
The graph has a trend of increasing temperature and amount of rain as you get up to the 7th column. After the 7th column, the trend shows decreasing rain and temperature.

To find the height of a pole, a surveyor moves 180 feet away from the base of the pole and then, with his eyes (4 feet above the ground), measures the angle of elevation to the top of the pole to be 44 degrees. Draw a picture and label a diagram to represent this situation. What is the height of the pole? Show your work.
Answer:
177.82397947 ft
Step-by-step explanation:
to find height of of the pole:
tan(44 degrees)=x/180
add the height of the person
x=(180tan(44 degrees) )+4
x=177.82397947 ft
now, round to what point you need to

The required, mode of the given data set is not defined. None of the options are correct.
What is the mode?In statistics, the mode is the value that appears most frequently in a data set. It is the most common observation or measurement in the data set. The mode is one of the measures of central tendency, along with the mean and median.
The mode is the value that appears most frequently in a data set. Since the given data set only has values of 10, 20, 30, 40, and 50, we can simply count which value appears most frequently. From the given options, the is no mode in the data, since it appears no value in the data set appears twice in the data set.

Answer:
[tex]1/9[/tex]
Step-by-step explanation:
when you divide a exponents, you subtract them. 4 - 0 = 4
3 to the power of 4 to the power of 2 = 3 to the power of 8, since exponents multiply.
3 to the power of negative 6 * 3 to the power of 8 = 3 to the power of negative 2, since multiplication adds the exponents when the base is equal.
3 to the power of negative 2 is 1/9

Which number produces an irrational number when multiplied by 1/4
Answer:
D
Step-by-step explanation:
1/4 x -36 = -9
1/4 x 4/3 = 1/3
1/4 x 12 = 3
But...
1/4 x 0.444444... = 0.111111...
So A is the answer
√12 produces an irrational number when multiplied by 1/4
What is an irrational number?A real number that cannot be expressed as a straightforward fraction is referred to as an irrational number. It cannot be described using a ratio. When p and q are integers and q is not equal to 0, N is not equal to p/q if N is irrational.
Given Four numbers to find the number that will produce an irrational number after dividing by 4. We will check them one by one:
For A, 0.4444:
=> 0.444
After multiplying by 1/4
=> 0.1111111
That can also write as 1/9(Not an irrational number)
For C, -√36:
=> -√36
After multiplying by 1/4
=>-√9/4
That can also write as 3/2(Not an irrational number)
For D, 4/3:
=> 4/3
After multiplying by 1/4
=> 1/3
That can also write as 1/3(Not an irrational number)
For B. √12:
=> √12
After multiplying by 1/4
=> √12/4
=>√(3/4)
That can also writes as √(3/4)(yes, an irrational number)
Therefore, The irrational number in the given option is B √12

minutes to get to work. Write an equation to determine how many minutes it takes Francesca to get to work.
36
- 12
36 = 2x - 12
36 - 2x + 12
36 = x+12
Answer:
[tex]\dfrac{x}{2}+12=36[/tex]
Step-by-step explanation:
As it is given that
Both Riley and Francesca commute to work.
And, the Riley takes 12 minutes more than as Francesca as Riley takes 36 minutes
So for determining how many minutes is required for Francesca to get to work we need
Let us assume the time taken by Francesca to get to work is x
So, the time taken by Riley is
[tex]= \dfrac{x}{2}+12[/tex]
And, Riley takes 36 minutes to get to work.
So, the equation would be
[tex]\dfrac{x}{2}+12=36[/tex]

Garrett has a current checking account balance of $495. Over the next three days, he receives a direct deposit of $775.75 from his job, pays an annual online banking fee of $34, and makes purchases of $44.21 and $7.92. He then withdraws $80 from an ATM that charges a $2.50 usage fee. What is Garrett's account balance at the end of the 3-day period? Write your answer in numeric form, such as 1369.05.
Answer:
1102.42
Step-by-step explanation:
495 + 775.75=1270.75
1270.75 - 34=1236.75
1236.75 - 44.21=1192.54
1192.54 - 7.92=1184.62
1184.62 - 82.2=1102.42
Answer:$1102.12
Step-by-step explanation: You just add the $775.75 to the original $495 then from there you subtract the rest of the numbers from the total amount and you get $1102.12
Solve the following system:
y = x + 3
3x + y = 19
O (7,4)
O(-4,7)
O (4,7)
O (4.-7)
Answer:
(4, 7) (third answer choice)
Step-by-step explanation:
In the system
y = x + 3
3x + y = 19
the first equation already gives y in terms of x. Thus we can substitute x + 3 for y in the second equation:
3x + (x + 3) = 19, which simplifies to:
4x = 16, yielding x = 4. Substituting 4 for x in the first equation, we get:
y = (4) + 3 = 7.
Thus, the solution is (4, 7) (third answer choice).
