Answer:

x = 62

y = 31

Step-by-step explanation:

x+(0)+(0-2)=60

x-2=60

x=62

(0)+y+(y-2)=60

y+y=62

y= 31

A smoke jumper jumps from a plane that is 1900 ft above the ground. The function h=-16t+1900 gives the jumper's height h in fee

Tatiana [17]

Answer:

a) The jumper opens the parachute in 7.5 seconds.

b) The jumper opens the parachute in approximately 7.706 seconds.

c) There are two possible choices for the function:

Case a): $Dom\{h(t)\} = [0\,s,7.5\,s]$ , $Ran\{h(t)\}=[1000\,ft,1900\,ft]$

Case b): $Dom\{h(t)\} = [0\,s,7.706\,s]$ , $Ran\{h(t)\}=[950\,ft,1900\,ft]$

Step-by-step explanation:

Note: The equation presented in statement is incorrect. The correct formula for free fall is:

$h(t)=-16\cdot t^{2}+1900$ (1)

Where:

$t$ - Time, measured in seconds.

$h$ - Height above the ground, measured in feet.

a) If we know that $h(t) = 1000\,ft$ , then the final instant of the free fall stage is:

$-16\cdot t^{2}+1900 = 1000$

$16\cdot t^{2} = 900$

$t = 7.5\,s$

The jumper opens the parachute in 7.5 seconds.

b) How long is the jumper in free fall if the parachute opens at 950 ft?

If we know that $h(t) = 950\,ft$ , then the final instant of the free fall stage is:

$-16\cdot t^{2}+1900 = 950$

$16\cdot t^{2} = 950$

$t \approx 7.706\,s$

The jumper opens the parachute in approximately 7.706 seconds.

c) There are two possible choices for the function:

Case a): $Dom\{h(t)\} = [0\,s,7.5\,s]$ , $Ran\{h(t)\}=[1000\,ft,1900\,ft]$

Case b): $Dom\{h(t)\} = [0\,s,7.706\,s]$ , $Ran\{h(t)\}=[950\,ft,1900\,ft]$

PLEASE HELP I WILL GIVE BRAINLIEST PLEASE

horrorfan [7]

Answer:

There are two main types of correlation coefficients: Pearson's product moment correlation coefficient and Spearman's rank correlation coefficient. The correct usage of correlation coefficient type depends on the types of variables being studied. We will focus on these two correlation types; other types are based on these and are often used when multiple variables are being considered.
