The table shows the approximate height of an object x seconds after the object was dropped. The function h(x) = –16x2 100 models

gregori [183]

The given model would make the least sense to use for x=-2.75.

the given function is:

$h(x)= -16x^2 +100$

a quadratic relationship,

where

h is the height in feet

x is the time in seconds

<h3>what is kinetic energy?</h3>

Kinetic energy is a form of energy that an object or a particle has by reason of its motion.

as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.

h(-2.75) = $-16*(-2.75)^2+100 = -21\\$

h(0.25) = $-16*0.25^2 +100=99$ $-0.25^2*16+100=99$

h(1.75) = $-16*1.75^2+100=51$

h(25) = $-16*2.25^2+100= 19$

therefore, x=-2.75 this model would make the least sense to use

How to divide 33 photos into two groups of the ratiol is 4 to 7

Dahasolnce [82]

Divide 33 photos into 2 groups.
The ratio of the said photo is 4 : 7
Now, we have the total number of photos which is 33, so let’s add the ratio to get the total number of ratio
=> 4 + 7 = 11
=> 33 and 11, let’s divide
=> 33 / 11 = 3, now we have the number of photos in each group.
=> 4 x 3 = 12
=> 7 x 3 = 21
Thus the ratio of photos is 12 : 21

PLEASE HELP ME I NEED HELP I WILL GIVE 35 POINTS

KATRIN_1 [288]

So, for each one you are trying to complete a full rotation or 360°. This means that you should add up all of the numbers and subtract that from 360.

#1. 360-279=81°
#2. 360-281=79°
