Equation given: $S = 16t^2$

S: distance fallen --> 1279 ft
t: time taken for the distance fallen

Solve:

$S = 16t^2\\1279=16t^2\\t^2 = 79.93\\t=8.9$

Thus it took 8 seconds for the thing to fall from the top

Hope that helps!

(1/3)9 to the third power =

AlekseyPX

The answer would be
1/3 * 9 = 3,
3^3 = 3*3*3, which then we multiply:
3*3=9, 9*3=27.
27 is the answer.

Hope this helps and have a nice day:)

Simplify sin^2y/sec^2 y−1 to a single trigonometric function

liubo4ka [24]

Answer:

$\frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y$

Step-by-step explanation:

We know that ${ \tan }^{2} y = { \sec }^{2} y - 1$

Also , ${ \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y }$

So ,

$\frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y$

What is the solution to log 5 (x+30)= 3

Free_Kalibri [48]

Answer:

x = 95

Step-by-step explanation:

Using the rule of logarithms

• $log_{b}$ x = n ⇔ x = $b^{n}$

Given

$log_{5}$ (x + 30) = 3, then

x + 30 = 5³ = 125 ( subtract 30 from both sides )

x = 95
