Answer:
y = 
Step-by-step explanation:
The equation used to find the equation for a line with two intercepts is called point slope form.
, where
and
are the intercept points and m is the slope.
However, we need the slope to use this formula.
Use 
m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}



y - ( -7 ) = m ( x - ( 4 ) )
y - ( -7 ) = -7/4 ( x - ( 4 ) )
y + 7 = -7/4 ( x + 4 )
y + 7 = 
y + 7 = 
y + 7 = 
y + 7 =
- 7
y = 
Answer:
A
Step-by-step explanation:
We want to solve the equation:

To do so, we can rewrite the equation.
Recall the double-angle for sine:

By substitution:

Distribute:

We can subtract 3cos(x) from both sides:

And factor:

Hence, our answer is A.
*It is important to note that we should not divide both sides by cos(x) to acquire 10sin(x) = 3. This is because we need to find the values of x, and one or more may result in cos(x) = 0, and we cannot divide by 0. Hence, we should subtract and then factor.

not right just need points
Answer:
See explanation
Step-by-step explanation:
cos62˚ ≈ 0.469
0.469 x 12 = 5.628
25 feet = 25 x 12 = 300 inches
First light is at 16 inches.
300 - 16 = 284 inches
Find the rest of the bulbs:
284 ÷ 4 = 71
Total number of lights = 71 + 1 = 72
Answer 72 lights
