All you do is multiply all the numbers together, and you get V = 168
A = p(1 + r/n)^nt
p = principal
r = rate, change to a decimal
n = number of times it is compounded per year
t = time in years
A = 10,000(1 + .055/12)^(12*(44/12))
Since the time is in months and the formulas is in years, I put the (44/12) to represent the time. This will actually simplify to 44.
A = 10,000(1 + .055/12)^(44)
A = $ 12,228.77
Answer:
The equation of the line would be y = -3/2x + 9
Step-by-step explanation:
In order to solve this, start by finding the slope of the original line. You can do this by solving for y.
2x - 3y = 12
-3y = -2x + 12
y = 2/3x - 4
Now that we have a slope of 2/3, we know that the perpendicular slope is -3/2 (since perpendicular lines have opposite and reciprocal slopes). We can use this and the new point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 6 = -3/2(x - 2)
y - 6 = -3/2x + 3
y = -3/2x + 9
Answer: x = -1/8
Step-by-step explanation:
Given the equation 9^x+1 - 13(3^x)+4=0
First, open the bracket, multiply 13 by 3
9^x+1 - 39^x+4=0
Combine like terms
9^x - 39^x +4 +1=0
40^x+5=0
Make x the subject
40^x=0 -5
40^x= -5
Divide both sides by 40
40^x/40=-5/40
x = -1/8
I hope this is clear, please mark as brainliest answer.
Legit way is vertex form
easy way is this
x value of vertex in form
f(x)=ax^2+bx+c is -b/2a
the y value is f(x value of vertex)
so
p(x)=-0.5x^2+40x-300
x value of vertex is -40/(2*-0.5)=-40/-1=40
max profit selling 40 per week
profit would be 500
