Answer:
A
Step-by-step explanation:
P^T is transpote matrix. So the rows of matrix P you write like columns in P^T.
So we have first row: 2, 5, it will be firsl column
2nd row: 8,1 will be 2nd column.
It is matrix:
2 8
5 1
This is matrix a)
4t + 75 => 475, t = 100

Answer:
$2.35
Step-by-step explanation:
Nickels are worth 5 cents each and quarters are worth 25 cents.
7 nickels = 7 * 5 cents = 35 cents
8 quarters = 8 * 25 cents = 200 cents
Total = 200 + 35 = 235 cents
There are 100 cents per dollar, so we can find the dollar value by:
235/100 = $2.35
◆ COMPLEX NUMBERS ◆
125 ( cos 288 + i sin 288 ) can be written as -
125.e^i( 288)
125.e^i( 288 +360 )
125.e^i( 288+ 720)
[ As , multiples of 360 can be added to an angle without changing any trigonometric functions or sign ]
To find the cube root , take the cube root of above 3 expressions ,
We get -
5 e^( i 96 )
5 e^( i 216 )
5 e^( i 336 )
Now using Euler's formula , We rewrite above as -
5 ( cos 96 + i sin 96 )
5(c os 216 + i sin 216 )
5 ( cos 336 + i sin 336 ) Ans.
