Rob is a geologist. he is surveying a conical crater that was created by a meteor impact. from one end to another, the crater forms a v shape. the deepest part of the crater is 400 feet deep. the depth of the crater varies at a rate of 0.25 foot with the horizontal distance from the west end of the crater the equation that models the depth of the crater, d, in feet, with respect to the horizontal distance in feet from the west end of the crater, h, is d =(1) the depth of the crater is 250 feet at horizontal distances of (2) and (3) feet from the west end (1) 0.25|x-400|-1,600 |x-0.25|-400 |x-400|-0.25 0.25|x-1,600|-400 (2) 600 800 1,000 1,200 (3) 1,800 2,000 2,200 2,400

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
