An object is thrown upward from the top of a 192 ft building with an initial velocity of 64 feet

Airida [17]

Answer:

t=6

Step-by-step explanation:

ground height = 0

(are you sure your formula is correct? isn't it - 16t²?)

if h=16t² +64t+192 is true then

16t² +64t+192 = 0

t² + 4t + 12 = 0

t = (-4 ± √(4² - 4*12)) / 2*1 = (-4 ± √-32) / 2 = -2 ± 2√-2

There is no solution of t

if it is h= - 16t² +64t+192

0 =- 16t² + 64t + 192

t² - 4t - 12 = 0

(t + 2) (t -6) = 0

t should be positive

t = 6 sec

What are the values of sin α and tan α, if: cosα=0.6

olganol [36]

Positive cosine is first or fourth quadrant. So we don't know the sign of the sine or the tangent.

Everybody's favorite right triangle is 3/4/5 and here we have

$\left(\dfrac 3 5 \right)^2 + \left(\dfrac 4 5 \right)^2 = 1$

So if

$\cos \alpha = 0.6 = \dfrac 3 5$

then

$\sin \alpha = \pm \dfrac{4}{5} = \pm 0.8$

and

$\tan \alpha = \dfrac{\sin \alpha}{\cos \alpha} = \dfrac{\pm 0.8}{0.6}=\pm \dfrac 4 3$
