The length of the day in Lagos, Nigeria (in minutes), ttt days since the beginning of the year can be estimated by this formula: \qquad L(t) = 727+22\sin \left(\dfrac{2\pi (t - 80.75)}{365}\right)L(t)=727+22sin( 365 2π(t−80.75) )L, left parenthesis, t, right parenthesis, equals, 727, plus, 22, sine, left parenthesis, start fraction, 2, pi, left parenthesis, t, minus, 80, point, 75, right parenthesis, divided by, 365, end fraction, right parenthesis. When is the longest day of the year? Give an exact answer.
Answers
Answer:
The longest day of the year is day 172
Step-by-step explanation:
Since the length of day is L(t)=727+22sin[2π(t−80.75)/365], the maximum length of day is obtained when sin[2π(t−80.75)/365] is at its maximum value which is 1. So. sin[2π(t−80.75)/365] = 1
We now solve this to find the day at which this maximum value occurs.
sin[2π(t−80.75)/365] = 1
[2π(t−80.75)/365] = sin⁻¹(1)
[2π(t−80.75)/365] = π/2
dividing both sides by 2π/365, we have
[2π(t−80.75)/365] ÷ 2π/365 = π/2 ÷ 2π/365
t−80.75 = 365/4
t−80.75 = 91.25
t = 91.25 + 80.75
t = 172
The longest day of the year is day 172

How many solutions can be found for the system of linear equations represented on the graph?
A) no solution
B) one solution
C) two solutions
D) infinitely many solutions
Answers
Answer:
D, ininitely many
Step-by-step explanation:
A- incorrect since the lines intersect
B - incorrect since the lines intersect at more than one point
C - incorrect since the lines intersect at more than 2 points
D- correct since the lines intersect at infinitely many points (since they're the same line)
Answer:
D) infinitely many solutions
Step-by-step explanation:
we can see that the graphs shows two lines that are exactly one on top of the other. This means that every point on either line will also coincide with a point on the other line.
Because of this, every point on one line is also a solution on the other line, thus there are infinitely many solutions.

Yak Travel Agency arranges trips for climbing Mount Everest. For each trip, they charge an initial fee in addition to \$0.15$0.15dollar sign, 0, point, 15 for each vertical meter climbed. For instance, the price for climbing all the way to the summit, which is 350035003500 meters above the base of the mountain, is \$645$645dollar sign, 645.
Let yyy represent the fee (in dollars) of a trip where they climbed xxx vertical meters.
Complete the equation for the relationship between the fee and vertical distance.
Answers
Answer:
[tex]y = 120 + 0.15x[/tex]
Step-by-step explanation:
Given
[tex]Additional\ Fee = \$0.15[/tex] per vertical meter
[tex]y = fee[/tex] per x meter
[tex]x = vertical\ meter[/tex]
For:
[tex]x = 3500[/tex] --- [tex]y = 645[/tex]
Required
Determine the equation that relates y to x
Let the initial fee be represented with m
The equation that relates y to x is:
[tex]y = Initial\ Fee + Additional\ Fee * Vertical\ Meter[/tex]
This gives
[tex]y = m + 0.15 * x[/tex]
We need to first solve for m
From the question,
[tex]x = 3500[/tex] when [tex]y = 645[/tex]
So:
[tex]645 = m + 0.15 * 3500[/tex]
[tex]645 = m + 525[/tex]
Make m the subject
[tex]m = 645 - 525[/tex]
[tex]m = 120[/tex]
So, the initial fee is $120
Substitute 120 for m in [tex]y = m + 0.15 * x[/tex]
[tex]y = 120 + 0.15 * x[/tex]
[tex]y = 120 + 0.15x[/tex]
Hence, the required equation is: [tex]y = 120 + 0.15x[/tex]

(Choice D)

[-1,2][−1,2]
Answers
Answer:
The option D represents an interval with a positive average rate of change.
Step-by-step explanation:
Let [tex]f(x) = x^{2}+10[/tex], the average rate of change on the interval [tex][a,b][/tex] is represented by the definition of the secant line:
[tex]\bar f = \frac{f(b) -f(a)}{b-a}[/tex] (1)
Where:
[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds, dimensionless.
[tex]f(a)[/tex], [tex]f(b)[/tex] - Function evaluated at lower and upper bounds, dimensionless.
Now we proceed to check each option:
A. [tex]a = -3[/tex], [tex]b = 3[/tex]
[tex]\bar f = \frac{19-19}{3-(-3)}[/tex]
[tex]\bar f = 0[/tex]
B. [tex]a = -4[/tex], [tex]b = -1[/tex]
[tex]\bar f = \frac{11-26}{(-1)-(-4)}[/tex]
[tex]\bar f = -5[/tex]
C. [tex]a = -3[/tex], [tex]b = 1[/tex]
[tex]\bar f = \frac{11-19}{1-(-3)}[/tex]
[tex]\bar f = -2[/tex]
D. [tex]a = -1[/tex]. [tex]b = 2[/tex]
[tex]\bar f = \frac{14-11}{2-(-1)}[/tex]
[tex]\bar f = 1[/tex]
The option D represents an interval with a positive average rate of change.

Step-by-step explanation:
Lynne was wondering which game was more popular so she aksed her friends which they liked to play more, FortNite or Among Us.
She found that of the 80 people who responded:
For fortnite:
0.55 of them preferred FortNite
Hence, = 0.55 × 80 people
= 44 people preferred fortnite
For Among us
30% of them preferred Among Us.
= 30% × 80 people
= 30/100 × 80 people
= 24 people preferred Among us.
How many more of her friends prefer FortNite than Among Us?
This is calculated as:
44 - 24
= 20 more people
Hence, 20 more of her friends prefer FortNite than Among Us

is 2(x+3)=5x+6-3x always true or never true?
Answers
Answer:

Step-by-step explanation:
Distribute the left side
2(x + 3) = 2x + 6
Simplify the right side
5x + 6 - 3x ← collect like terms

Thus
left side = right side , so always true
Equation 2(x + 3) = 5x + 6 - 3x is an identity which is always true.
What is identity?An identity is an equation which is always true, no matter what values are substituted.
Identities can be written with the sign ≡.
Given equation,
