The answer is going to be A because if you flip the shapes the angles do not meet each other.

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)

If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s t)(-7)? A. -439 B. -141 C. 153 D. 443 please answer quick this t

nika2105 [10]

We're trying to find $s(t(-7))$ .

$t(-7)=3(-7)$

$t(-7)=-21$

$s(-21)=2-(-21)^2$

$s(-21)=2-441$

$s(-21)=-439$

Hope this helps.

頑張って!
