Answer:
The answer is less than 50 degrees
explanation:
The solar elevation angle is the altitude of the Sun, the angle between the horizon and the centre of the Sun's disc. Since these two angles are complementary, the cosine of either one of them equals the sine of the other. They can both be calculated with the same formula, using results from spherical trigonometry.
Answer:
After 5 years, savings account = $241.00
After 8 years, savings account = $269.53
Step-by-step explanation:
If the savings account increases by 3.8% per year, this means it will be 103.8% of the previous year's value since 100% + 3.8% = 103.8%
103.8% in decimal form = 103.8/100 = 1.038
Therefore, the exponential function is:
, where
is the number of years
So when
,

After 5 years, savings account = $241.00
After 8 years, savings account = $269.53
The sign of the term in x^2 is negative so the graph will open downwards.
when x = 0 y = 1
The coordinates of the vertex are (0,1)
the maximum value of the function is 1
and the axis of symmetry ix x = 0 ( the y axis)
