A ball is thrown vertically in the air with a velocity of 95 ft/s. The ball is at a height of 120 ft.

sattari [20]

Answer:

The ball is at a height of 120 feet after 1.8 and 4.1 seconds.

Step-by-step explanation:

The statement is incomplete. The complete statement is perhaps the following "A ball is thrown vertically in the air with a velocity of 95 ft/s. What time in seconds is the ball at a height of 120ft. Round to the nearest tenth of a second."

Since the ball is launched upwards, gravity decelerates it up to rest and moves downwards. The position of the ball can be determined as a function of time by using this expression:

$y = y_{o} + v_{o}\cdot t +\frac{1}{2}\cdot g \cdot t^{2}$

Where:

$y_{o}$ - Initial height of the ball, measured in feet.

$v_{o}$ - Initial speed of the ball, measured in feet per second.

$g$ - Gravitational constant, equal to $-32.174\,\frac{ft}{s^{2}}$ .

$t$ - Time, measured in seconds.

Given that $y_{o} = 0\,ft$ , $v_{o} = 95\,\frac{ft}{s}$ , $g = -32.174\,\frac{ft}{s^{2}}$ and $y = 120\,ft$ , the following second-order polynomial is found:

$120\,ft = 0\,ft + \left(95\,\frac{ft}{s} \right)\cdot t +\frac{1}{2}\cdot \left(-32.174\,\frac{ft}{s^{2}} \right) \cdot t^{2}$

$-16.087\cdot t^{2} + 95\cdot t -120 =0$

The roots of this polynomial are, respectively:

$t_{1} \approx 4.075\,s$ and $t_{2} \approx 1.831\,s$ .

Both roots solutions are physically reasonable, since $t_{1}$ represents the instant when the ball reaches a height of 120 ft before reaching maximum height, whereas $t_{2}$ represents the instant when the ball the same height after reaching maximum height.

In nutshell, the ball is at a height of 120 feet after 1.8 and 4.1 seconds.

Find The last two digit of 36^2015

olga nikolaevna [1]

Answer:

76

Step-by-step explanation:

The last two digits of powers of 36 repeat in a pattern of length 5:

36^1 mod 100 = 36

36^2 mod 100 = 96

36^3 mod 100 = 56

36^4 mod 100 = 16

36^5 mod 100 = 76

36^6 mod 100 = 36

The last two digits of the power 2015 are the same as those of the 5th power: 76.

Please show work for it.

Komok [63]

Answer:

7over9 or -7over9

Step-by-step explanation:

81x power 2 - 8 = 41

(left side) (right side)

first we let the 8 from left side go to the right side,so it will be +8:

81x power 2 = 41+ 8

=49

so now we let the 81 from left side go to right side, so it will be ÷81:

x power 2= 49 over 81

and now we let the power 2 (square) go to the other side so it will become square root:

x = + - √49 over 81

at the end, you will get 2 answers which is 7 over 9 and - 7 over 9
