The submarine would be 1,620 ft if i’m understanding the question correctly
Answer:
The correct option is A.
Step-by-step explanation:
The correct form is:
4sin^2 x − 1 = 0
First step is add 1 to both sides:
4sin^2 x-1+1=0+1
4sin^2 x=1
Now to eliminate 4 divide both sides by 4
4sin^2 x/4=1/4
sin^2 x=1/4
Take square root at both sides
√sin^2 x = √1/4
sinx = 1/2
Thus the correct option is 30° ....
A) 60q/12
b) set ^ this equation equal to the one on the paper, move the variable to one side, and the rest should be easy from there
c) he loses profits
Answer:

Step-by-step explanation:
Slope-intercept form equation is given as 
Where,
y = distance remaining
x = hours driven
m = slope/constant rate. In this case, the value of m would be -65. This means the distance will reduce at a constant rate of 65 miles per hour.
b = y-intercept, which is the initial value or the distance between the cities = 420
Plug in the values into the slope-intercept equation, to represent the distance y in miles remaining after driving x hours. You would have:
