In New York City at the spring equinox there are 12 hours 8 minutes of daylight. The
slamgirl [31]

Answer:

  independent: day number; dependent: hours of daylight

  d(t) = 12.133 +2.883sin(2π(t-80)/365.25)

  1.79 fewer hours on Feb 10

Step-by-step explanation:

a) The independent variable is the day number of the year (t), and the dependent variable is daylight hours (d).

__

b) The average value of the sinusoidal function for daylight hours is given as 12 hours, 8 minutes, about 12.133 hours. The amplitude of the function is given as 2 hours 53 minutes, about 2.883 hours. Without too much error, we can assume the year length is 365.25 days, so that is the period of the function,

March 21 is day 80 of the year, so that will be the horizontal offset of the function. Putting these values into the form ...

  d(t) = (average value) +(amplitude)sin(2π/(period)·(t -offset days))

  d(t) = 12.133 +2.883sin(2π(t-80)/365.25)

__

c) d(41) = 10.34, so February 10 will have ...

  12.13 -10.34 = 1.79

hours less daylight.

Is -4 a solution to the equation 5+(-8)n=29
e-lub [12.9K]

The answer you are looking for is -3.

To find this answer, you must get "n" by itself. First subtract 5 from both sides. You would get (-8)n = 24, which you then divide -8 on both sides, to get a final answer of n = -3.

I hope this helps!

HELPPPP PLEASEEE 45 POINTSSS

Using the numbers in the given equation:

a =-2, b = 6 and c = -5

The vertex form is written as : a(x+d)^2 + e

we need to find d and e:

d = b/2a = 6/2(-2) = -3/2

e = c-b^2/4a = -5 - 6^2/4(-2) = -1/2

Now substitute the letters for their values in the vertex form formula above:

-2(x-3/2)^2 -1/2

The vertex is (3/2, -1/2)

2. The formula begins with a negative number ( -2) so the Parabola opens downwards.

3. To find the intercept replace x with 0 and solve for y:

the intercept is (0,-5)
