Answer:
A. {-4, -3, 7, 8}
Step-by-step explanation:
The ordered pairs representing a function are always written ...
(input, output)
<h3>Inputs</h3>
The set of inputs for the given function is the list of first-numbers of the ordered pairs. Those numbers are -3, -4, 8, 7. When we express them as a set, we like to have the elements of the set in increasing order:
inputs = {-4, -3, 7, 8} . . . . . . matches the first choice
Hi there!
3413 steps = 1.27 miles.
To find the amount of steps in 1 mile, we must divide both sides by 1.27.
3413 / 1.27 steps = 1.27 / 1.27 miles
2687.4 steps = 1 mile.
Hence, in order to walk at least 1 mile, we must take 2688 steps.
5v+8=93
Subtract 8 from both sides.
5v=85
Divide both sides by 5.
v=17

tan37=r/8
r=8tan37
r≈6 in rise per step (to nearest whole inch)
2b
11*12/6=22 steps needed to climb the 11 ft to the entrance

tanα=14/20
α=arctan(7/10)
α≈35° (to nearest whole degree)
..
3b
tanα=21/17
α=arctan(21/17)
α≈51° (to nearest degree)
X =/= 4, -4
Explanation: if you replace the values of “x” with either “4” or “-4”, then one or more of the denominators will equal 0. Since you can not divide by zero, “X =/= 4, -4” is the correct solution.
