Answer:
A: sin(55.13+22.62) = .969
B: Cos(55.13-22.62) = .861
C: sin(2*55.13) = .96
D: cos(2*55.13) = -.28
E: tan(55.13+22.62) = 3.9375
F: cot=1/tan= 1/tan(55.13-22.62)= 1.6969
Step-by-step explanation:
I would like to preface this by saying that my trig is probably rusty so maybe double check my work. I will try to overexplain it so you can easily spot any errors I may make
To solve for x we know that sin(x)=4/5
we can solve for x by using the arc sin
This means that x=arcsin(4/5) which gives me around x=53.13
We can then use the same process for y but with 5/13
so arcsin(5/13) gives us around y=22.62
Then it's just a matter of plugging everything in
A: sin(55.13+22.62) = .969
B: Cos(55.13-22.62) = .861
C: sin(2*55.13) = .96
D: cos(2*55.13) = -.28
E: tan(55.13+22.62) = 3.9375
F: cot=1/tan= 1/tan(55.13-22.62)= 1.6969

Which of the following is a Recursive Formula for an Arithmetic Sequence?
a1 = -2, an = an-1 + 5
an = 5n – 7
a1 = -2, an= 5an-1
an = -2 + 5(n – 1)
Answers
Answer:
The correct answer is Option 1: a1 = -2, an = an-1 + 5
Step-by-step explanation:
A recursive formula is a formula that uses previous term in order to calculate the next term in a sequence.
In case of arithmetic sequence, the next term is obtain by adding a specific number to the last term.
This can be written as:
[tex]a_n = a_{n-1}+d[/tex]
Here
a_n is the terms we are calculating
a_{n-1} is the previous term and d is the common difference.
If we compare the given options, we can see that only option 1 matches with the general form of recursive formula
an = an-1 + 5
Here
5 is the common difference
Hence,
The correct answer is Option 1: a1 = -2, an = an-1 + 5

Answer:
A. For each input value, x, there is exactly one output value, y.
Step-by-step explanation:
A function always have exactly one output value (y-value) that is related or assigned to each input value (x-value), however, two different x-values can have the same y-value.
In the graph given, although two different values have the same y-value, every x-value has exactly one y-value corresponding to it. No x-value has two different y-values.
Therefore, the graph represents a function.

Answers
Answer:
y=3/4x-4
Step-by-step explanation:
First you put x to the other side of the equation, so you have 4y = 3x-16. Next you need to get y alone so you get 4y/4=y. But, you need to do this to both sides of the equation, so you do 3x-16/4=3/4x-4. All in all, your slope-intercept form is y=3/4x-4.

Given:
The ratio of boys to girls is [tex]\dfrac{4}{5}[/tex].
Number of boys = 24
To find:
The number of girls.
Solution:
We have,
Boys: Girls = 4:5
Let the number of boys be 4x and number of girls be 5x.
[tex]4x=24[/tex]
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
Now,
Number of girls = [tex]5x[/tex]

Jean's bedroom is 13 feet by 13 feet. She has chosen a carpet which costs $28.60 per square yard. This includes installation.
Answers
Answer:
$528.8
Step-by-step explanation:
Given data
Dimension
13 feet by 13 feet
1 ft =4.3 yard
Area= 4.3^2
Area= 18.49 yard
cost of carpet
1 yard= $28.60
18.49 yard= x
cross multiply
x= 18.49*28.60
x=$528.8
Hence the cost to cover the room is $528.8
what is the Y interpret of the question? y=-1/2x-6
Answers
Answer:
The y-intercept is (0,-6)
Step-by-step explanation:
In the equation y = mx + b, b is the y-intercept. In your equation, the b is -6, so the y-intercept is (0,-6).
Answer:
Y-intercept: (0, -6)
Step-by-step explanation:
We have to determine the "y-intercept" in the equation.
The equation is written out in slope-intercept form: y = mx + b
The "b" variable would be our y-intercept, or beginning point.
In the y = -1/2x-6 equation, you would see that the "-6" is in place of the "b" variable.
Therefore, the y-intercept of the line would be (0, -6).
