Using his telescope tommy watches a bald eagle as it sits ono top of a cliff. The telescope is positioned so that the line of sight to the eagle forms a 38 degree angle of elevation. The telescope sets s1.3 m above the ground and the base of the telescope is 116 m from the base of the cliff. Round to the nearest tenth
Question :
How high above the ground is the eagle?
Answer:
91.9 m
Step-by-step explanation:
From the diagram :
We can obtain h, using the trigonometric relation :
Tanθ = opposite / Adjacent
Opposite = h
Adjacent = 116
Tan 38° = h / 116
0.7812856 = h / 116
h = 0.7812856 * 116
h = 90.629132
Eagle's height above the ground :
h + 1.3m
h = 90.629132m
Height above the ground = 90.629132 + 1.3 = 91.9 m above the ground.

Estimate the line of best fit using two points on the line.
(5, 60)
(3, 44)
O A. y= 5x + 20
O B. y = -5x + 16
O C. y= -8x + 16
D. y = 8x+ 20
The estimated equation of line is y = 8x+ 20
What is linear equation?
A linear equation is defined as an equation in which the highest power of the variable is always one.
Two points on the line (5, 60), (3, 44)
[tex]y- y_1= \frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
[tex]y- 60 = \frac{60-44}{5-3} (x-5)[/tex]
[tex]y- 60 = \frac{16}{2} (x-5)[/tex]
[tex]y = 8 (x-5)+ 60[/tex]
[tex]y = 8x+ 20[/tex]
Hence, the estimated equation of line is y = 8x+ 20

This recipe makes 20 cupcakes. Deepak only wants to make 15 cupcakes. How much of each ingredient does he need? Recipe: Makes 20 cupcakes 10 ounces butter 12 ounces sugar 8 ounces flour 4 eggs
Answer:
9.6 ounces of butter, 8 ounces of sugar, 12 ounces of flour, 4 eggs
Explanation: 20 / 16 = 4/5. 16 is four-fifths of 20. So multiply 4/5 with everything.
12 * 4/5 = 9.6 ounces
10 * 4/5 = 8 ounces
15 * 4/5 = 12 ounces
5 * 4/5 = 4 eggs
