The equation Y=3/4x+3/2 is a slope intercept form equation for line AB.
What is equation?An equation is a mathematical statement that two expressions are equal. It consists of two expressions separated by an equals sign and can contain numbers, variables, and operators. Equations are used to solve problems, make predictions, and describe relationships between different quantities. Equations can also be used to represent physical laws and other phenomena.
This equation is written in the form y=mx+b, where m is the slope of the line and b is the y-intercept of the line. In this equation,
the slope m is equal to 3/4 and the y-intercept b is equal to 3/2. The slope of the line AB is 3/4, so the line has a positive slope, and the y-intercept of the line AB is 3/2.
This equation can be used to find the coordinates of any point on the line AB, as well as the equation of the line itself.

If you borrow $800 for 10 years at an annual interest rate of 12%, how much will you pay altogether?
Answers
Answer:
the principal amount is 10000 is the rate of interest is 10 and the number of years is 10 you can calculate the simple interest a is equal to 10000 1 + 0 is equal to 1.6 is equal to 16000 interest is equal to a - b is equal to 6000 - 1000
Answer:
$1,760
Step-by-step explanation:
So I'm assuming the interest is simple interest rate which means that the interest applied each year is 12% of the original amount.
So this means that we can find the interest rate from one year by finding 12% of 800, and to do this we convert 12% to a decimal by dividing by 100 to get 0.12 and then use this decimal value to multiply by 800 to get: 0.12 * 800 = 96.
This means annually $96 will be charged in interest. To find how much interest there is after 100 years, simply multiply by 10, to get $96 * 10 = $960.
This is only the interest rate, it's like a fee, you still have to pay back the original amount, so all together you pay: $ borrowed + interest
So we add the interest rate 960 to the amount borrowed 800 to get: 960 + 800 = 1,760

Answers
The value is J = 1.71*10^-6 kmol/m^2.s
According to the given conditions we get,
The length the tube l= 0.20m
The diameter of the tube d= 0.01m
The total pressure inside the tube P= 101.32kPa
The partial pressure of CO2 at the first end is
P1= 456mm Hg = 60794.832 Pa
The partial pressure of CO2 at the other end is
P2= 76mm Hg = 10132.472 Pa
The temperature is T = 298 K
The diffusion coefficient D= 1.67* 10^-5 m^2/s
Generally the molar flux of CO2 is mathematically represented as
J= D{p1-p2} / R.T

A company wishes to manufacture a box with a volume of 40 cubic feet that is open on top and is twice as long as it is wide. Find the width of the box that can be produced using the minimum amount of material.
Answers
The width of the box is 3 ft that can be produced using the minimum amount of material.
What are the volume and surface area of a box?Consider a box with length 'l', width 'w' and height 'h',
Volume V = l × w × h
Surface area S = 2(lw + wh + hl)
Calculation:It is given that,
Volume of the box V = 36 cubic feet and l = 2w
Using the formulae,
V = 2w × w × h = 2w²h ...(1)
S = (2w² + 2wh + 4wh) = 2w² + 6wh ... (2) (here only single lw is considered since it is open top)
From equation (1),
36 = 2w²h
⇒ w²h = 18
⇒ h =18/w²
equation (2) becomes
S = 2w² + 6w(18/w²) = 2w² + 108/w ...(3)
So, for a minimum amount of material, the width of the box is,
On differentiating the surface area w.r.t 'w'
S' = 4w - 108/w²
For a minimum amount, substituting S' = 0 we get,
0 = 4w - 108/w²
⇒ 4w = 108/w²
⇒ 4w³ = 108
⇒ w³ = 27
∴ w = 3 feet
Therefore, the width of the given box is 3 feet.
