3 sin x + 5 cos x = 0
3 sin x = - 5 cos x /: cos x ( divide both sides by cos x )
3 sin x / cos x = - 5
3 tan x = - 5
tan x = -5/3
x = arc tan (-5/3)
x ≈ - 59.036°
Answer:
Geometric sequence
Step-by-step explanation:
A geometric sequence is when you multiply or divide with a constant number. So in 1, 5, 25, 125, and 625, we're multiplying by 5 every time. I hope this helped :)
Answer:
3.2 miles per hour
Step-by-step explanation:
Time=75 minutes=75/60=5/4=1.25 hours
Speed=Distance/time=4/1.25=3.2 miles per hour
David's jogging rate is 3.2 miles per hour.
Answer:
The equation of the line is y - 16 = 3(x - 3)
Step-by-step explanation:
To find the equation of this line, we first need to find the slope. To do that, we use the slope equation.
m(slope) = (y2 - y1)/(x2 - x1)
m = (16 - 4)/(3 - -1)
m = (16 - 4)/(3 + 1)
m = 12/4
m = 3
Now that we have the slope, we can use it and either point in point-slope form.
y - y1 = m(x - x1)
y - 16 = 3(x - 3)
