Find the equation of a line parallel to y=4x−4 that contains the point (−2,0). Write the equation in slope-intercept form.
Allushta [10]

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

y=\stackrel{\stackrel{m}{\downarrow }}{4} x-4\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}

so we're really looking for the equation of a line whose slope is 4 and passes through (-2 , 0)

(\stackrel{x_1}{-2}~,~\stackrel{y_1}{0})\qquad \qquad \stackrel{slope}{m}\implies 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{4}(x-\stackrel{x_1}{(-2)}) \\\\\\ y=4(x+2)\implies y=4x+8

Can someone please solve these?
JulijaS [17]

Answer:

Step-by-step explanation:

h = -6t^{2} +20t + 4

I will use calculus,  maybe that's not how you're supposed to do this

-12t +20 =0

12t = 20

t = 20 /12

t = 1 \frac{8}{12}

t = 1 \frac{2}{3}

there will be a max at  1.6666666666  seconds

-6*1.6666666666666^{2}  + 20 * 1.6666666666  +4

= 16.666666666666 + 33.333333333333 + 4

= - 16\frac{2}{3} + 33 \frac{1}{3} + 4

= 20\frac{2}{3}  feet max height ( not too high,  for a rocket)

time of flight:

0 = -6t^{2} +20t + 4

use quadratic formula to find t

-20 +- sqrt [ 20^{2} - 4*(-6)*4 ] / 2*(-6)

-20 +- sqrt [400 + 96 ] / -12

-20 +- sqrt [496 ] / -12

-20 +- 22.27105 / -12

try the negative option 1st

-42.27105 / -12

3.522 seconds.     time of flight

when will the rocket be at 12' ? :

12 = -6t^{2} +20t + 4

0 = -6t^{2} +20t -8

use quadratic formula again to find t

-20 +- sqrt [ 20^{2} - 4*(-6)*(-8) ] / 2*(-6)

-20 +- sqrt [ 400 - 192 ] / -12

-20 +- sqrt [208 ] / -12

-20 - 14.4222 / -12

-34.4222 / -12

2.8685 seconds ( on the way down)

and

-20 + 14.4222 / -12

-5.578 / - 12

0.4648  seconds ( on the way up )
