A rocket is launched from atop a 65-foot cliff with an initial velocity of 113 ft/s. The height of the rocket above the ground a
OlgaM077 [116]

Answer:

7.6 seconds

Step-by-step explanation:

To solve this problem we can use the following equation:

S = So + 113*t + at^2/2

Where S is the final position, So is the inicial position, Vo is the inicial speed, a is the acceleration and t is the time.

In this problem, we have that S = 0, So = 65, Vo = 113 and a = -32 ft/s2 (The acceleration of gravity)

So we have that:

0 = 65 + 113t - 16t2

16t2 - 113t - 65 = 0

Using Bhaskara's formula, we have:

Delta = 113^2 + 4*65*16 = 16929

sqrt(Delta) = 130.11

t = (113 + 130.11) / (2*16) = 7.597 seconds

Rounding to nearest tenth, we have t = 7.6 seconds

You have a 3-card deck containing a king, a queen, and a jack. You draw a random card, then put it back and draw a second random
hichkok12 [17]
Probability that you will draw exactly 1 king

P(draw both jacks) = 1/3*1/3 = 1/9P(no jacks) = 2/3*2/3 = 4/9P(1 jack) = 1 - 1/9 - 4/9 = 4/9

Please explain, thanks! :)<br><br> Multiply DE

First, we have to make sure that the number of columns in the first matrix is equal to the number of rows in the second matrix.

\left[\begin{array}{cc}1&-3&2&0\\\end{array}\right] *   \left[\begin{array}{ccc}2&3&4\\1&2&3\end{array}\right]

Since this is true, we can continue to solve the problem.
To multiply two matrices, multiply each row element in the first matrix by each column element in the second matrix. For example:
1*2 = 2
-3*1=-3
Then we add them to get our new matrix element.
-3+2=-1
Then we move to the next column of the second matrix.
1*3=3
-3*2=-6
-6+3=-3
Then the final column of the second matrix.
1*4=4
-3*3=-9
-9+4=-5
Our matrix so far:
\left[\begin{array}{ccc}-1&-3&-5\\x&x&x\end{array}\right]
We do the same for the bottom row of the first matrix.
<em>First Column</em>
2*2=4
0*1=0
4+0=4
<em>Second Column
</em>2*3=6
0*2=0
6+0=6
<em>Third Column</em>
2*4=8
0*3=0
8+0=8
Our final matrix is:
\left[\begin{array}{ccc}-1&-3&-5\\4&6&8\end{array}\right]
