Cot(t)= cos(t) / sin(t)
Cos(t) = sqrt(1 - sin^2(t) ) But this is in quad 4, so sin(t) <0
cot(t) = sqrt(1 -sin^2(t)) / - sint(t)
cot(t) = - sqrt( 1 - sin^2(t) ) / sin(t)
Answer:
1/6 cause there is a 1 in 6 chance each time you roll the die
Step-by-step explanation:
First, given graph is very inaccurate. I suppose that you made net with pen.
a) The slope is the angle ( tan∡) between your graph and x axis.
The slope represent the level of the earnings growth.
b) According to the given graph y-intercept= 30$
Y-intercept represent starting amount of money.
c) If we accept that y=70 is connected with x=2 and y=30 with x=0
The slope is S= (70-30)/2= 40/2=20
Linear equation for this function is
y= 20x+30
d) When we replace y=300$ in the equation we get
20x+30=300 => 20x=300-30 => 20x=270 => x=270/20=13.5h
x=13.5h
Good luck!!!
