Hey You!

12/40 = Candidate A.

18/40 = Candidate B.

12 + 18 = 30

40 - 30 = 10

10/40 = Those who didn't vote.

ANSWER:

12 ÷ 40 = .3 (30%) So 30% voted for Candidate A.

18 ÷ 40 = .45 (45%) So 45% voted for Candidate B.

10 ÷ 40 = .25 (25%) So 25% didn't vote at all.

PLEASE HELP!! Is the answer 50 seconds???

Answer:

Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m

Step-by-step explanation:

Let

x -----> the time in seconds

y ----> altitude in meters

we have

$g(x)=\frac{1}{20}x(x-100)$

$g(x)=\frac{1}{20}x^{2}-5x$

This is a vertical parabola open upward

The vertex is a minimum

To find out the lowest altitude, find the vertex

Complete the square

Factor the leading coefficient

$g(x)=\frac{1}{20}(x^{2}-100x)$

$g(x)+125=\frac{1}{20}(x^{2}-100x+2,500)$

Rewrite as perfect square

$g(x)+125=\frac{1}{20}(x-50)^{2}$

$g(x)=\frac{1}{20}(x-50)^{2}-125$

The vertex is the point (50,-125)

therefore

Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m (below the sea level)
