They're perpendicular.
Both equations are in the form y=mx+b, where m is the slope and b is the y-intercept.
Perpendicular lines have opposite reciprocal slopes (ex: the opposite reciprocal of 5 is -1/5).
Parallel lines have the same slope, but different y-int.
Answer:
0.8
Step-by-step explanation:
0.8x250=200, which is the closest tenth of a decimal.
Answer:
to two decimal places
= 6.04 mega joules
Step-by-step explanation:
The volume of the half tank
= πr²h
r= 2 m
h= 14/2= 7 m
Volume= 22/7 *2² *7
Volume= 88 m³
work (in mega-joules) needed to pump all of the water to the top of the tank
= Volume*mass density *acceleration*distance
= 88*1000*9.8*7
= 6036800 joules
In mega joules
= 6.036800 mega Joules
to two decimal places
= 6.04 mega joules
Answer:
The answer is below
Step-by-step explanation:
The total revenue from the sale of a popular book is approximated by the rational R(x) = 1100x^2/x^2 + 4, where x is the number of years since publication and the total revenue in millions of dollars. Use this function to complete parts a through d. (a) Find the total revenue at the end of the first year. $ million (b) Find the total revenue at the end of the second year. $ million (c) Find the domain of function R. Choose the correct domain below. {x | x is a real number and x greaterthanorequalto 0} {x | x is a real number and x lessthanorequalto 5} {x | x is a real number and x notequalto 2, x notequalto 5} {x | x is a real number and x notequalto 2}
Solution:
Revenue is the total money made from the selling of a product or item.
a) Given the revenue function:

At the end of the first year (i.e. x = 1), the venue is given as:

b) At the end of the second year (i.e. x = 2), the venue is given as:

c) The domain of the function is the value of the denominator for which the value of the denominator is not zero
x² + 4 ≠ 0
The domain is {x| x is a real number and x ≥ 0}
