Use the right triangle and the given information to solve the triangle. a=5 B=53degrees find b c and A
Answers
Answer: A = 37°
c = 8.31
b = 6.63
Step-by-step explanation:
I suppose that the triangle is something like the one below.
Then we know the measure of an angle and the length of the adjacent cathetus.
a = 5
B = 53°
Now we can use the relationships:
Tan(B) = (opposite cathetus)/(Adjacent cathetus) = b/a
Cos(B) = (adjacent cathetus)/(hypotenuse) = a/c
Sin(B) = (opposite cathetus)/(hypotenuse) = b/c
Then we have:
Tan(53°) = b/5
Tan(53°)*5 = b = 6.63
So we found the length of b.
Now we can use the second relationship to find the length of c:
cos(53°) = 5/c
c = 5/cos(53°) = 8.31
Now, to find the angle A we can use the fact that the sum of all interior angles of a triangle must be equal to 180°
We know that is a triangle rectangle, so we have an angle equal to 90°, this one is C = 90°, and we also know that B = 53°
Then:
A + B + C = 180°
A + 53° + 90° = 180°
A + 53° = 180° - 90° = 90°
A = 90° - 53° = 37°
Then:
A = 37°
c = 8.31
b = 6.63

The graphs of functions fand g are shown.
Function g is defined as g(x) = f(x) - C. What is the value of c?
The value of c?
Answers
Answer:
c = 3
Step-by-step explanation:
Function g is defined as,
g(x) = f(x) - c
Which states that the image function 'g' is formed by shifting function 'f' by c units down along y-axis.
Since, function 'f' has been shifted 3 units down to form the image function 'g'.
Therefore, value of c = 3 will be the answer.

Answer: A) Yes, because the number can be written as the quotient of two integers
=====================================================
Explanation:
Any repeating decimal can be expressed as a fraction of two integers.
---------------------------------------
Optional section:
Here's a proof showing how the given number can be expressed as a fraction
Let x = 0.020020200202002...
The block of digits "02002" repeats forever.
Multiply both sides by 10^5 = 100,000 to move the decimal over 5 spots to the right.
The equation
x = 0.020020200202002...
will turn into
100000x = 2002.0200202002...
We have this system of equations
[tex]\begin{cases} x = 0.020020200202002\ldots\\100000x = 2002.0200202002\ldots\end{cases}[/tex]
Subtracting said equations leads to
100,000x - x = 99,999x on the left
2002.0200202002... - 0.0200202002... = 2002 on the left
Note how the decimal portions line up perfectly to cancel out when we subtract
After those two subtractions, we end up with the equation
99,999x = 2002
Divide both sides by 99,999 and we isolate x
x = 2002/(99,999)
Use your calculator to find that,
2002/(99,999) = 0.02002020020202...
which helps confirm our answer.

Answers
Answer:
B: Is transferred to capital reserve account if the investment long term investment
D: Is transferred to profit and loss A/c only if the investment is current investment
Step-by-step explanation:
Fixed assets are long term investments and when these assets are sold at a profit, the profit on the sale of such investment is usually transferred to Capital Reserve Account.
Meanwhile, current assets are current investments and when these assets are sold at a profit, the profit on the sale of such investment is usually transferred to profit and loss account.
Thus, options B & D are correct.

A polygon on a coordinate grid was transformed using the rule(x,y)>(x-4,y-3).Which of the following describes this transformation
Answers
Answer:
True
Step-by-step explanation:
Step 1: Find the Coordinates of the Original Triangle
(2, -2)
(6, -3)
(5, 2)
Step 2: Apply the Transformation to the Coordinates
(2-(4),-2+(3)) -> (-2, 5)
(6-(4),-3+(3)) -> (2, 0)
(5-(4),2+(3)) -> (1, 5)
Step 3: Compare the points on the red triangle with the points you got
(-2, 5) = (-2, 5)
(2, 0) = (2, 0)
(1, 5) = (1, 5)
Because the coordinates are the same we can conclude that the triangle was transformed with the rule: (x,y)-> (x-4,y+3)

Answer: Number 7 is not a function. Also number 8 is not a function.
Step-by-step explanation:
Number 7s x and y values in the table do not increase or decrese at a constant rate so the table is not a function.
Number 8_ So the x input 6 has two y outputs so that makes it not a function. In other words an input or x value only has 1 and only 1 output to make it a function.

Suppose the solutions of a homogeneous system of five linear equationsin six unknowns are all multiples of one nonzero solution. Will thesystem necessarily have a solution for every possible choice of constantson the right sides of the equations? Explain.
Answers
Step-by-step explanation:
The problem can be written as
Ar = where A = 5×6 matrix. dim(NullA)=1 as all the multiples of Ar=0
are the multiple of one non zero solution.
Since A is 5×6 , A n= 6
rank(A)= n-dim(Nul A)= n-1= 6-1=5
now, imagine A as 5 dimensional subspace of R^5( As A has 5 rows)
Therefore Col(A)= R^5
This means that Ar = b has a solution for every b.

your local park let's you swim in the community pool 8 times in one month. how many times will you be able to swim in the community pool for 3 years and 5 months
Answers
Answer:
136 times
Step-by-step explanation:
If the park lets you swim 8 times in one month, there are 12 months in one year, therefore you could swim eight times each of those twelve months. 8 x 12 = 96. Then, you have 5 more months left to swim. So, if you swam eight times each month that would be 8 x 5 = 40. So, 96 + 40 = 136.
A company that manufactures widgets has fixed cost of $9,186.00 each month and a cost of $2.75 for each widget it produces which of the following equations could be used to determine the total production cost for the company if it produced X what is last month let X represent the number of widgets the factory produce last month and Y represent the total production cost from the factory

Answer:
[tex]y = \$9186.00 + \$2.75x[/tex]
Step-by-step explanation:
Given
[tex]Fixed\ Cost = \$9186.00[/tex]
[tex]Cost\ per\ widget =\$2.75[/tex]
Required
Determine an expression for this scenario
x = number of widgets
y = total cost
The expression for y is calculated as follows:
[tex]y = Fixed\ Cost + Cost\ per\ widget * Number\ of\ widgets[/tex]
Substitute values for the fixed cost, the cost per widget and the number of widgets
[tex]y = \$9186.00 + \$2.75 * x[/tex]
[tex]y = \$9186.00 + \$2.75x[/tex]

A possible confounding variable is the amount of exercise. Those that drink carrot juice may be more concerned about their health and exercise more, which explains the healthy heart conditions.
A possible confounding variable is eating dinner at a fast-food restaurant. Those that eat at fast-food restaurants are more likely to not drink carrot juice and the fast food would explain the healthy heart conditions.
