Answer:

  D.  -16/5

Step-by-step explanation:

-3.2 = -32/10 = -16/5 . . . . matches choice D

_____

<em>More detail</em>

Any finite decimal can be converted to a fraction by considering the place value of the digits.

  3.2 = 3×1 + 2×(1/10)

  = 3 + 2/10 = (30 +2)/10 = 32/10

Then common factors can be cancelled from numerator and denominator.

  32/10 = (2·16)/(2·5) = 16/5

The negative sign can be applied as required.

  -3.2 = -(3.2) = -(16/5) = -16/5

A flying cannonball’s height is described by formula y=−16 <img src="https://tex.z-dn.net/?f=%20t%5E%7B2%7D%20" id="TexFormula1"
Morgarella [4.7K]
Y = -t ^ 2 + 300t - 16
 We find the first derivative and calculate its roots.
 We make the second derivative, and calculate the sign taken in it by the roots of the first derivative, and if:
 f '' (a) <0 is a relative maximum
 f '' (a)> 0 is a relative minimum

 y '= - 2t + 300 = 0
 -2t + 300 = 0
 t = 300/2 = 150

 y'' = - 2
 y'' (150) = - 2 (is a relative maximum)

 the highest point of the trajectory is reached for t = 150s.
 The height for that time is
 y = - (150) ^ 2 + 300 (150) - 16 = 67484
 
 answer
 67484
 t = 150s.

WILL GIVE BRAINLIEST ANSWER !!
Snowcat [4.5K]

Answer:

Option: C is the correct answer.

C) Use the straightedge to draw the line through points C and D.

Step-by-step explanation:

Katie is constructing the circumscribed circle for △RST.

The next step in the construction of the circumscribed circle is:

Use the straightedge to draw the line through points C and D.

( Since on drawing a straight edge that passes through point C and D we get a point where the line AB and CD meets that point will be considered as the center of the circumscribed circle ).

Hence, option: C is correct.

Yay


derivitives

everything is taken derivitve in repsect to time

da/dt=10cm^2/s

alright
area=pir^2
da/dt=2pir dr/dt
10cm^2/s=2pir dr/dt
r=10
\frac{10cm^2}{sec}=2\pi 10cm\frac{dr}{dt}
\frac{10cm^2}{sec}=20\pi cm \frac{dr}{dt}
divide both sides by 20pi
\frac{10cm^2}{20cm \pi sec}= \frac{dr}{dt}
\frac{1cm}{2\pi sec}= \frac{dr}{dt}

the rate of change of the radius when radius=10 is \frac{1cm}{2\pi sec}
