Answer:

3.25

16/13 = 4/r

16 × r = 13 × 4

16r = 52

r = 52/16 = 3.25

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

(I’ll mark brainliest ) The cross country running team is hosting their first home race and needs to plan and set up the course.
Aneli [31]

Answer:

Smallest: 15,840 ft

Largest: 16,896 ft

Step-by-step explanation:

1 mi = 5,280 ft

Setup proportion to solve for the <u>smallest</u>:

\frac{1mi}{5,280ft} =\frac{3mi}{xft}

Do butterfly method and you should get this:

xft=3(5280)\\x=15,840ft

Setup proportion to solve for the <u>largest</u>:

\frac{1mi}{5,280ft} =\frac{3.2mi}{xft}

Butterfly method:

xft=3.2(5280)\\x=16,896ft
