The function f(x) = 700(0.5)x/100 models the amount in pounds of a particular radioactive material stored in a concrete vault, where x is the
number of years since the material was put into the vault. Find the
amount of radioactive material in the vault after 60 years. Round to the
nearest whole number.
462 pounds

i dont know

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
