Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 14 feet by 14 feet by 4 inches for a patio if the concrete costs $145.00 per cubic yard? (1yd³=27ft³)

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

okay then that is your answer you know that 4 bottlkes of water cost ten $ at the music festival

step-by-step explanation:

c=x-39/5

x=39/5+c

step-by-step explanation:

answer-

the equation that models this pattern is

solution-

a researcher placed a petri dish with 32,000 bacterial cells. one hour after being placed in the vacuum chamber, the number of cells in the petri dish had halved. another hour later, the number of cells had again halved.

this can be represented as exponential decreasing function,

where,

putting the values,

y-intercept means, where x=0, so

the coordinate of this poin will be (0, 32000)

this means when x=0 or at the starting of the research, the number of bacteria cells was 32000.

after 3 hours, number of bacteria cells will be,

the   coordinate of this point will be (3, 4000)
