what is the measure of angle m?
Answers
Answer:
The answer is 55.
m=55
Step-by-step explanation:
we know that a straight line is 180
We know that m+125 is a straight line.
This means that we will subtract 125 from 180
When you do that, you get 55.
We can check our answer by doing 125+55
That will get you 180.
The men's U.S. Open tennis tournament is held annually in Flushing Meadow in New York City. In the first round of the tournament, 64 matches are played. In each successive round, the number of matches played decreases by one half.
Find a rule for the number of matches played in the nth round. For what values of n does your rule make sense?
Answers
Using a geometric sequence, it is found that the rule for the number of matches played in the nth round is given by:
[tex]a_n = 64\left(\frac{1}{2}\right)^n[/tex]
The rule makes sense for values of n of at most 6, as in the last round, which is the 6th and final round, 1 game is played.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, we have that:
In the first round of the tournament, 64 matches are played, hence the first term is [tex]a_1 = 64[/tex].In each successive round, the number of matches played decreases by one half, hence the common ratio is [tex]q = \frac{1}{2}[/tex].Thus, the rule is:
[tex]a_n = 64\left(\frac{1}{2}\right)^n[/tex]
The last round is the final, in which 1 game is played, hence:
[tex]1 = 64\left(\frac{1}{2}\right)^n[/tex]
[tex]\left(\frac{1}{2}\right)^n = \frac{1}{64}[/tex]
[tex]\left(\frac{1}{2}\right)^n = \left(\frac{1}{2}\right)^6[/tex]
[tex]n = 6[/tex]
Hence, the rule makes sense for values of n of at most 6, as in the last round, which is the 6th and final round, 1 game is played.

Marvin earns $7.75 per hour at his summer job. He wants to buy a video game system that costs $193.75.
Enter an equation to model the relationship between the number of hours worked h and the amount earned e.
Answers
Answer:
If he earns (e) $7.75 per hour, this implies e = 7.75h.
Step-by-step explanation:
If you wanted to solve that-
e = 7.75h
193.75 = 7.75h
Divide both sides by 7.25
h = 25

What are m and b in the linear equation, using the common meanings of m and b?
2 + 3x + 5 - 2x =
Answers
Step-by-step explanation:
the usual line equation is
y = mx + b
I personally rather write it
y = ax + b
but really, all letters are possible as needed (particularly, if certain letters are already used for other parts of the problem definition).
what is important is to understand the messaging of the parts of such equations independently of what letter is used for what.
the factor of x (usually m in these equations) is the slope of the line, its incline. it is expressed as the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.
the constant term (often called b in these equations) is the y-intercept (the y value when x = 0, indicating where the line is intercepting the y-axis).
I guess the equation in your problem actually looks like
2 + 3x + 5 - 2x = y
so, let's combine similar terms
3x - 2x + 2 + 5 = y
x + 7 = y
and now compare this to the general line equation, and we find
m = 1
b = 7
The model for long-term average temperature f (x), in degrees Celsius, at the Willburn airport is represented by the equation f of x is equal to 5 times sine of the quantity x over 12 end quantity plus 14 and 5 tenths period If x represents the month of the year, in which months will the temperature be 17°C?
x equals pi over 6 plus 2 times pi times n and x equals 5 times pi over 6 plus 2 times pi times n

x = 2π + 24πn and x = 10π + 24πn
Answers
Answer:
need more info
Step-by-step explanation:
what are we sloving
The expression that represents the month of the year, in which months will the temperature be 17°C is x = 2π
How to determine the month of the year?The function is given as:
f(x) = 5sin(x/12) + 14.5
When the temperature is 17°C, the equation becomes
5sin(x/12) + 14.5 = 17
Subtract 14.5 from both sides
5sin(x/12) = 2.5
Divide both sides by 5
sin(x/12) = 0.5
Take the arc sin of both sides
x/12 = π/6
Multiply both sides by 12
x = 2π
Hence, the expression that represents the month of the year, in which months will the temperature be 17°C is x = 2π

The value of y when x is 0 is called the y-intercept because (0,y) is the point at which the line crosses the y-axis.
