Dimas [21]

Step-by-step explanation:

The height of the swipe card is given by :

$h(t)=-3t^2+15t+18$ .....(1)

We need to find the maximum height of the swipe card and the time to reach the maximum height.

For maximum height, put dh/dt = 0

So,

$\dfrac{d}{dt}(-3t^2+15t+18)=0\\\\-9t+15=0\\\\t=\dfrac{15}{9}\\\\t=1.67\ s$

It will take 1.67 seconds to reach the maximum height.

Now, put t = 1.67 s in equation (1).

$h(1.67)=-3(1.67)^2+15(1.67)+18\\\\=34.68\ feet$

Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.

Please help and explain with these 2 math questions!!!!!!

Volgvan

1) -10x+y=4

Now, you should substitute x in every situation.

* x=-2 => -10*(-2)+y=4... 20+y=4... y=-16

* x=-1 =>-10*(-1)+y=4... 10+y=4... y=-6

*x=0 => -10*0+y=4... y=4

* x=1 => -10*1+y=4... -10+y=4... y=14

* x=2 => -10*2+y=4... -20+y=4... y=24

2) -5x-1=y

For example: x=0

-5*0-1=-1
