15. What is the solar altitude on the 4th of July in Washington, D.C., at latitude 39"N? a.22.7 b.73.7 c.23.5 d.51° e.90° 16. Th
kirill115 [55]

Answer:

answer 15  correct option is b. 73.7°

answer 16 correct option is с. 47°

Explanation:

we know that on 4th july Northen hemisphere have summer and Washington, D.C also in Northen hemisphere

and sun present at 23.5° latitude

so latitude of sun is calculate as given figure below

= 90° - ( 39° - 23.5° )

= 74.5°

so correct option is b.73.7

this difference if because we take latitude 23.5°  that is approx on 24 july

but july 4 latitude will be some low

and

we know during summer declination angle is + 23.5 in N.H.

and during winder declination angle is - 23.5 in N.H.

and at spring and autumn sun is at equator

the declination angle change is

declination angle change = 27.5 + 27.5 = 47°

Directions and Analysis

Task 1: Functions and Transformations

Transformations can be thought of as functions that take the points from one object (the pre-

image) to the corresponding points on another object (the image). In the unit, you saw

examples of how algebra can be used to rewrite the coordinates of points after they have

been transformed. You can also use function notation to rewrite the coordinates. For

example, these statements show several different ways you can use function notation for the

translation, T, of a point 6 units in the positive x-direction:

• T(x, y) = (x + 6, y)

T:(, y) = (x + 6, y)

• T<6, 0>(x, y) = (x + 6, y)

16. o(x, y) = (x + 6, 9)

.

a. Write functions for the following transformations using function notation. Choose a

different letter to represent each function. For example, you can use R to represent

rotations. Assume that a positive rotation occurs in the counterclockwise direction.

translation of a units to the right and b units up

reflection across the y-axis

reflection across the x-axis

rotation of 90 degrees counterclockwise about the origin, point o

rotation of 180 degrees counterclockwise about the origin, point o

rotation of 270 degrees counterclockwise about the origin, point oExplanation:
