Answer:
f(x)=500+60x
So, B.
Step-by-step explanation:
Opening balance =500
Deposits= 60__ monthly
Write as a function
Represent the number of months with x and the balance at any month with f(x)
f(x) is calculated as thus:
Opening Balance + Deposits * Number of Months
So, we have:
f(x)=500+60*x
So, f(x) = 500+60x
Answer:
n=−43/3
Step-by-step explanation:
−42/3=2n/3+1/3+n/3
−14=2/3n+1/3+1/3n
−14=(2/3n+1/3n)+(1/3)
−14=n+1/3
Flip the equation.
n+1/3=−14
Subtract 1/3 from both sides.
n+1/3−1/3=−14−1/3
n=−43/3
Answer:
207
Step-by-step explanation:
Sec(theta) = 1 / cos (theta) = hypotenuse / x -coordinate
hypotenuse = 1 (because it is the radius of the unit circle)
sec (theta) = 1 / (-3/5) = - 5/3
cot (theta) = 1 / tan(theta) = x-coordinate / y - coordinate
cot (theta) = -3/5 / y
y^2 + (-3/5)^2 = 1 => y^2 = 1 - 9/25 = 16/25 = y = +/- 4/5
Third quadrant => y = -4/5
=> cot (theta) = (-3/5) / (-4/5) = 3/4
