That's is depend from the author of the equation. But most time there is need to multiply value X into constant before.
In other words it look likes
y=2*x-3

Answer:

Length of the room is 180 ft

Step-by-step explanation:

We have a rectangular room with dimensions:

width = 70 ft and length "x" (unknown)

Perimeter of a rectangle is 2*w + 2*x and according to problem statement 500 ft of lights will fit exactly in room perimeter then:

2*70 + 2*x = 500

140 + 2*x = 500

2*x = 500 - 140

2*x = 360

x = 360/2

x = 180 ft

The diameter of a round skating

Tema [17]

Answer: 47 meters

Step-by-step explanation:

The equation for the diameter of a circle is $C=d\pi$ , so we just multiply the diameter (15) by $\pi$ . $15\pi$ , or roughly 47.1238898038. Rounded to the nearest meter, 47 meters. Also, happy pi day!

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
