The second option is the right one
Higher the watts means the highest the intensity of that light bulb. also, the slope would be 1.1 which is positive and directly related to the watts. if watts goes up, then the function value will also go up.
Answer:
Total cost of polishing the floor is Rs/500.
Step-by-step explanation:
The floor consists of 2000 tiles which have the shape of a rhombus.
Area of rhombus =
Where: and are the diagonals.
Given that:
= 40 cm = 0.4 m
= 25 cm = 0.25 m
Then,
Area of each tile =
=
= 0.05
Area of each tile is 0.05 .
Since there are 2000 tiles on the floor of the building, then;
Total area covered by the tiles = 0.05 x 2000
= 100
The total cost of polishing the floor = 100 x Rs/5
= Rs/500
Answer:
The y intercept is (0, 8). The equation of the function is f(x) = 10x + 8
Step-by-step explanation:
Given that after 1 hour of work, Jack will make 18 dollars and the slope is 10, subtract 10 dollars from 18 dollars to find his set amount, or y-intercept.
18 - 10 = 8 dollars.
Now that we have the m and b values, we can create our equation.
The equation in standard form is f(x) = mx +b, where m = the slope and b = the y-intercept. Plug our values in and the equation will be f(x) = 10x + 8. You can test if this is correct by plugging in x values from the table and seeing if your calculated value correctly corresponds to the given y value in the table.
