Step-by-step explanation:

Soemthing is a function if it can pass the vertical line test

the vertical line test is when you draw a vertical line and it only touches the graph once

Another way of thinking about this is no function can have two of the same values on the x axis

I'm not too sure what's happening with the third response but the answer is B

Find the 60th term of the arithmetic sequence <br> −29,−49,−69,...

Mariulka [41]

Answer:

-1209

Step-by-step explanation:

Your sequence has first term a1 = -29 and common difference d = -20. Using these in the formula for the n-th term, we can find the 60 term.

an = a1 +d(n -1)

an = -29 -20(d -1)

a60 = -29 -20(60 -1) = -1209

Vesna [10]

$(2^8 \times 5^{-5} \times 19^0)^{-2} \times (\dfrac{5^{-2}}{2^3})^4 \times 2^{28} =$

$= 2^{-16} \times 5^{10} \times 1 \times \dfrac{5^{-8}}{2^{12}} \times 2^{28}$

$= 2^{-16} \times 5^{10} \times 5^{-8} \times 2^{-12} \times 2^{28}$

$= 2^{-16} \times 2^{-12} \times 2^{28} \times 5^{10} \times 5^{-8}$

$= 2^{-16-12+28} \times 5^{10-8}$

$= 2^{0} \times 5^{2}$

$= 1 \times 25$

$= 25$
