Answer the following True or False:

Mathematics
1 answer:

False; consider as a counterexample the function <em>f</em> : ℝ→ℝ defined by

f(x)=\begin{cases}-3&\text{for }x\neq2\\0&\text{for }x=2\end{cases}

Clearly <em>f</em> approaches -3 as <em>x</em> gets closer to -2, but neither limit from either side is equal to the function's value at <em>x</em> = 2 (that is, -3 ≠ 0), so <em>f</em> is not continuous.

HELP ME SOMEOME PLEASE!!!!!​
mart [117]

Problem 1

For functions like f(x), the input is x and the output is f(x).

If x = 7, then f(7) = 12 has the input 7 and output 12.

Therefore the ordered pair is (7, 12) which is the answer

=====================================================

Problem 2

Replace every x with 3 and simplify

f(x) = 3*x

f(3) = 3*3

f(3) = 9

The input x = 3 leads to the output y = 9. Recall that y = f(x).

So (3,9) is the answer here.

The Eiffel Tower is 324 m tall. If a tourist is looking at it from 100 m away from the base,
romanna [79]

Answer:

80,94º

Step-by-step explanation:

What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).

So I calculated the tangent of the angle of the tourist.

The formula is tan=Oposite side/adjacent

tan=\frac{opposite side}{adjacent}

tan=\frac{324}{100} =3.24

And now with your calculator you press "shift" and "tan". Then introduce 3,24 and it will give you the result (80,94º).

I hope it helped.
