aleksley [76]3 years ago
8 0

Answer:

The first table. (By that, I am referring to the table directly under the question)

Step-by-step explanation:

A function has only one y value for every x value. Thus, for example the coordinates (-5, -5) and (-5, 5) could not be a function.

To find the height of a pole, a surveyor moves 150 feet away from the base of the pole and then, with a transit 4 feet tall, mea
ladessa [460]

Answer: The answer is 139 feet

H = height of the pole =?

BC = ED = height of the transit = 4 ft

CD = BE = distance moved away from the base of the pole = 140 ft

Consider the ΔABE

tan44 = AE/BE

tan44 = h/140

h = 140 tan44

h = 135.2 ft

H = height of pole = AE + ED = h + ED = 135.2 + 4

H = 139.2 ft

The function c = 100 + 0.30m represents the cost c (in dollars) of renting a car after driving m miles. What would the cost be t
aleksley [76]

Answer:

c = $130

Step-by-step explanation:

Given:

c = 100 + 0.30m

Where,

c = cost of renting a car (in dollars)

m = number of miles driven (in miles)

If m = 100 miles

c = 100 + 0.30m

= 100 + 0.30(100)

= 100 + 30

= 130

c = $130

PLEASE HELP
xeze [42]

Answer:

-4

Step-by-step explanation:

So we are given the expression: | y - x | + y - 1, and we have our values for (x,y): (-3,-6).

So, we can just start plugging things in and simplifying, so:

| -6 + 3 | - 6 - 1 = | -3 | -7

                       = 3 - 7

                       = -4

therefore, the actual distance is 280 miles.
