The answer would be 199/37 or 5 14/37
They are 7 points away from each other.
Answer:
Step-by-step explanation:
We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).
Note that x=1 is a <em>vertical line </em>since x is 1 no matter what y is.
This means that if our new line is perpendicular to the old, then it must be a <em>horizontal line</em>.
So, since we have a horizontal line, then our equation must be our y-value of our point.
Our y-coordinate of our point (8,-9) is -9.
Therefore, our equation is:
And this is in standard form.
And we're done!
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The capacity of the metal tank is
The duration usage is
The cost of 2000-gallon tank 15 years ago is
The capacity of the second tank considered is
The power sizing exponent is
The initial construction cost index is
The new construction after 15 years cost index is
Equation for the power sizing exponent is mathematically represented as
=> Here is the cost of 5,000-gallon tank as at 15 years ago
So
Equation for the cost index exponent is mathematically represented as
Here is the cost of 5,000-gallon tank today
So
=>
=>
