Answer:
The answer to your question is the letter D.
Step-by-step explanation:
Data
length = 16 ft
angle = 71°
Opposite side = ?
Process
1.- To answer this question use trigonometric functions.
The trigonometric function that relates the Opposite side and the hypotenuse is sine.
2.- Write the trigonometric function
sin Ф = Opposite side / hypotenuse
3.- Substitution and result
sin (71) = x / 16
The decimal for 8/18 is 0.44, you simplify 8/18 to 4/9, divide 4 by 9 for the decimal.
Answer:
5
Step-by-step explanation:
substitute 2 for t
-16(2)^2+32(2)+5=5
For a hyperbola

where

the directrix is the line

and the focus is at (0, c).
Here, we have c = 5, a² = 9, so b² = 5² - 9 = 16.
a = √9 = 3
b = √16 = 4
Your hyperbola's constants are ...
a = 3
b = 4
______
Please note that the equation of a hyperbola has a negative sign for one of the terms. The equation given in your problem statement is that of an ellipse.
Find the slope of line 1
The equation of line 1 is y = (1/3)x + 5
m = 1/3
Find the slope of line 2
Line 2 is parallel to line 1. Parallel lines have the same number of slope. So the slope of line 2 is 1/3
Find the slope-intercept form of equation, with m = 1/3 and (-9,5)
General formula
y - y₁ = m(x - x₁)
Input the number to the formula
y - y₁ = m(x - x₁)
y - 5 = 1/3(x - (-9))
y - 5 = 1/3 (x + 9)
y - 5 = (1/3)x + 3
y = (1/3)x + 3 + 5
y = (1/3)x + 8
The equation is y = (1/3)x + 8
