Whats LN? *with picture*
Answer:
LN = 15 in
Step-by-step explanation:
We can say that arc PL plus arc LM is equal to arc PM:
arcPL + arcLM = arcPM
We can substitute what we have:
10 + 14 = arcPM
arcPM = 24.
Since both arcPM and arcLN equal 24, we can say they are congruent.
In circles, congruent arcs create congruent chords, so, we can say PM = LN.
Since PM is 15, LN = 15 in
Solve the following quadratic equation for all values of xx in simplest form.
5(2x+1)^2+6=26 cant figure this out!!
Answer:
x=1/2 and x=-3/2
Step-by-step explanation:
5(2x+1)^2+6=26
5(2x+1)^2=20
(2x+1)^2=4
2x+1=±2
Now make two equations and solve both for x:
2x+1=2
2x=1
x1=1/2
2x+1=-2
2x=-3
x2=-3/2

Which statement describes the sequence defined by a Subscript n Baseline = StartFraction n squared minus 16 Over n cubed + 4 EndFraction? The sequence diverges. The sequence converges to 0. The sequence converges to 1. The sequence converges to ∞.
Calculating the limit as n goes to infinity, it is found that:
The sequence converges to 0.
------------------------------
The sequence is given by:
[tex]a_n = \sum_{n=0}^{\infty} f(n)[/tex]
In which
[tex]f(n) = \frac{n^2 - 16}{n^3 + 4}[/tex]
------------------------------
If the limit of f(n) as n goes to infinity is a value, it converges to this value.If the limit of f(n) as n goes to infinity is infinity, it diverges.------------------------------
The limit is:
[tex]\lim_{n \rightarrow \infty} f(n) = \lim_{n \rightarrow \infty} \frac{n^2 - 16}{n^3 + 4}[/tex]
Since it is a limit going to infinity, we consider just the terms with the highest exponents in the numerator and the denominator. Thus:
[tex]\lim_{n \rightarrow \infty} \frac{n^2 - 16}{n^3 + 4} = \lim_{n \rightarrow \infty} \frac{n^2}{n^3} = \lim_{n \rightarrow \infty} \frac{1}{n} = \frac{1}{\infty} = 0[/tex]
Thus: The sequence converges to 0.

the equation of the line that is perpendicular to the line with equation y=-2x-1 and passes through the point (1, -2) is?
Answer:
[tex]y=\frac{1}{2} x-\frac{5}{2}[/tex]
Step-by-step explanation:
Hi there!
Note that:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Perpendicular lines always have slopes that are negative reciprocals of each other (ex. 3 and -1/3, 5/6 and -6/5, etc.)1) Determine the slope (m)
When we look at the given line, [tex]y=-2x-1[/tex], we can identify that -2 is in the place of m, the slope of the line. Because perpendicular lines are negative reciprocals of each other, we know that a line perpendicular to this would have a slope of [tex]\frac{1}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{1}{2} x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=\frac{1}{2} x+b[/tex]
Plug in the given point (1,-2)
[tex]-2=\frac{1}{2}(1)+b\\-2=\frac{1}{2}+b[/tex]
Subtract 1/2 from both sides
[tex]-2-\frac{1}{2}=\frac{1}{2}+b-\frac{1}{2}\\-\frac{5}{2} = b[/tex]
Therefore, the y-intercept of the line is [tex]-\frac{5}{2}[/tex]. Plug this back into [tex]y=\frac{1}{2} x+b[/tex]
[tex]y=\frac{1}{2} x-\frac{5}{2}[/tex]

During a trip, a driver travelled a distance of 80km at an average speed of 60km/hr.He then changed his speed and travelled the remaining 20km of his journey at 30km/hr. What was the drivers average speed for the entire journey?
Show all working!!
Answer:
50 km/hr
Step-by-step explanation:
D = RT
Time for first part of trip = 80/60 = 4/3 hr.
Time for second part of trip = 20/30 = 2/3 hr.
total time for entire trip = 4/3 + 2/3 = 6/3 = 2 hr.
Total distance = 100 km
Average rate of speed for entire trip = 100/2 = 50 km/hr

a whale costs $14700 and depreciates in value by 8% per year. When will the whale be worth $100
Answer:
x = 60
Step-by-step explanation:
The question is asking
$14,700 * (1 - 8%)^x = $100
$14,700 * (1 - 0.08)^x = $100
$14,700 * (0.92)^x = $100
(0.92)^x = $100/$14,700
log(0.92^x) = log($100/$14,700)
x * log(0.92) = log(0.0068027)
x = log(0.0068027)/log(0.92)
x = 59.85
Since this question is asking in terms of years, we always round up (in this case to 60), as it won't fully be worth $100 by the beginning of the 59th year.

C.2(5x-2)+2(3x+1)=42 yes or no
D.5x-2+3x+1+5x-2=42 yes or no
THERE CAN BE MORE THAN ONE ANSWER.
thank you
Answer:
A.NoAs,
5x - 2 + 5x - 2 + 3x + 1 = 13x - 3 = 42
But here,
13x - 2 which is not equal to 13x - 3
Hence, it's wrong.
B. NoAs,
5x - 2 + 5x - 2 + 3x + 1 = (10x - 4) + (3x + 1) = 42
But here,
(10x - 2) + (3x + 1) which is not equal to (10x - 4) + (3x + 1)
Hence, it's wrong.
C. NoAs,
5x - 2 + 5x - 2 + 3x + 1 = 2(5x - 2) + 3x + 1 = 42
But here,
2(5x-2)+2(3x+1) which is not equal to 2(5x - 2) + 3x + 1
Hence, it's wrong.
D. YesAs,
5x - 2 + 5x - 2 + 3x + 1 = 42
Also,
5x-2+3x+1+5x-2 equal to 5x-2+3x+1+5x-2
Hence, it's correct.
