What are the zeros of f(x) = x^2 - 12x+ 36

yuradex [85]

Answer:

x = 6

Step-by-step explanation:

0 = x^2 -12x + 36 solve by factoring ...or Quadratic Formula

0 = ( x-6)(x-6) shows zeroes ( both of them) are x = 6

Write an equation in slope-intercept form for the line that has the given slope and contains the point. Please show some work.(

zavuch27 [327]

Answer:

An equation in the slope-intercept form will be:

$y=\frac{-1}{2}x+0$

Step-by-step explanation:

Given the points

(4,-2)

(2,-1)

Finding the slope between points

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(4,\:-2\right),\:\left(x_2,\:y_2\right)=\left(2,\:-1\right)$

$m=\frac{-1-\left(-2\right)}{2-4}$

$m=-\frac{1}{2}$

We know that the slope-intercept form of the line equation is

$y=mx+b$

where m is the slope and b is the y-intercept.

substituting the values m=-1/2 and the point (4, -2) to determine the y-intercept i.e. 'b'.

$y=mx+b$

$-2=\frac{-1}{2}\left(4\right)+b$

$-2+b=-2$

$b=0$

substituting the values m=-1/2 and b=0 to determine the line equation in slope-intercept form

$y=mx+b$

$y=\frac{-1}{2}x+0$

Thus, an equation in the slope-intercept form will be:

$y=\frac{-1}{2}x+0$

The function y = -16x2 + 1500 gives a parachute jumper's height y in feet

earnstyle [38]

Answer:

Step-by-step explanation:

so the question is asking about the time from 1500 feet to 1100 feet. How long did they fall, w/o a parachute. aka "freefall" so, at 1500 feet the jumper is really at time zero. so, plug in to the formula

1100 = -16 $x^{2}$ +1500

( x represents seconds so i'll change it to t so we know it's time )

1100 = -16 $t^{2}$ + 1500

now we can solve for t , to see how long the jumper falls

-400 = - 16 $t^{2}$ ( subtracting 1500 from both sides of equation )

25 = $t^{2}$ ( dividing both sides by -16 )

oh.. look at how nice that turns out.. :)

$\sqrt{25}$ = t ( take the square root on both sides )

5 = t

the jumper fell for 5 seconds to get to 1100 feet
