If m <1= 36 what is the measure of its complement?

Vlada [557]

If A represents an angle, its complement is 90-A.

If m<1 = 36, then its complement is 90-36 (degrees), or 54 (degrees).

The point P=(3/4, y) lies on the unit circle. What is the value of y in simplest form?

laila [671]

Answer:

Step-by-step explanation:

if (x,y) is any point on unit circle then

x²+y²=1²

x²+y²=1

(3/4)²+y²=1

9/16+y²=1

y²=1-9/16=(16-9)/16=7/16

y=±√7/16

A rocket is launched from the top of a 55-foot cliff with an initial velocity of 138 ft/s.

melisa1 [442]

For this case we have that the equation that describes the height is:

$h = -16t ^ 2 + vt + c$

Where,

v: initial speed

c: initial height

Substituting values we have:

$h = -16t ^ 2 + 138t + 55$

Then, to find the time, we use the quadratic formula:

$t =\frac{-b +/-\sqrt{b^2 - 4ac} }{2a}$

Substituting values we have:

$t =\frac{-138 +/-\sqrt{138^2 - 4(-16)(55)} }{2(-16)}$

Rewriting:

$t =\frac{-138 +/-\sqrt{19044 + 3520} }{-32}$

$t =\frac{-138 +/-\sqrt{22564}}{-32}$

$t =\frac{-138 +/-150.21}{-32}$

We discard the negative root because we want to find the time.

We have then:

$t =\frac{-138 -150.21}{-32}$

$t =\frac{-288.21}{-32} \\t=9$

Answer:

D. $0 = -16t^2 + 138t + 55; 9 s$
