Answer:
y = 40x + 30
Step-by-step explanation:
The equation for a linear function is given by:
y = mx + b;
where y and x are variables, m is the slope or rate of change of the function and b is the initial value of y at x = 0 (that is y intercept).
Let y represent the total cost and x represent the number of hours worked.
The electrician charges 110 after 2 hours of work and 190 for 4 hours of work.
Representing in coordinate form as (x, y) we get:
(2, 110) and (4, 190)
The equation of the function can be gotten using the formula:
Therefore:
Answer:
r=2.9cm
Step-by-step explanation:
we know the formula, mass= density*volume
as a result we can figure out the volume = mass/density
=485/8 cm^3
=60.625cm^3
here comes another formula of volume of cone =
we will use this to find the radius,
=60.625
=181.875
h is 70mm which we will turn to 7cm
*7=181.875
=8.27
r=2.875825cm
r=2.9cm
nice question. hope this helps
