Answer:
Option 3 3 1/8x - 6 3/10
Step-by-step explanation:
(3 1/2x - 4 1/10) - (3/8x + 2 1/5)
Divide it into parts:
(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)
3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x
-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10
So we get:
2 1/4x - 6 3/10
Answer:
Step-by-step explanation:
C is 135'
A is 90'
B is 90'
D is 45'
E is 45'
F is 135'
First you find the length of the green rectangle by using a^2 + b^2 = c^2
So that means 4^2 + 7^2 = length of green
That equals 8.1 when you square root it.
Then, you use 8.1^2 + 3^2 (which is the green rectangle height) to find the red line using the same equation
So your answer is 8.6 cm.
Answer:
At Maximum point;
x(max) = 50
p(max) = $100
Maximum revenue = $5,000
Step-by-step explanation:
The price function is;
p(x) = 200 − 2x
where
p is the price (in dollars) at which exactly x trucks will be rented per day.
The revenue function R(x) can be written as;
R(x) = p(x) × x
Substituting p(x) equation;
R(x) = (200-2x)x
R(x) = 200x-2x^2 ........1
To maximize R(x), at maximum point dR/dx = 0
differentiating equation 1;
dR/dx = 200 - 4x = 0
4x = 200
x = 200/4
x = 50
Substituting x = 50 into p(x)
p(50) = 200 - 2(50) = $100
p = $100
Maximum revenue is;
R = p × x = $100×50
R = $5,000
