Find ????⋅ ???? if |????|=3 , |????|=9 , and the angle between ???? and ???? is π2 radians.

mrs_skeptik [129]

Answer:

$a{\cdot}b=0$

Step-by-step explanation:

It is given that,

Magnitude of a A, $|A|=3$

magnitude of B, $|B|=9$

The angle betwern a and b is $\dfrac{\pi}{2}\ rad=90^{\circ}$

Dot product,

$a{\cdot} b=|a||b|\ \cos\theta\\\\a{\cdot} b=3\times 9\times \ \cos(90)\\\\a{\cdot} b=0$

So, a.b is equal to 0.

a 10 ft ladder leans against a wall with its foot braced 3ft. from wall's base how far up the wall does the ladder resach

geniusboy [140]

Ladder makes a right triangle with the wall and ground. The hypotenuse = length of the ladder = 10 ft
Let the height be h
By Pythagorean theorem
10^2 = 3^2 + h^2
h^2 = 10^2 - 3^2 = 100 - 9 = 91
h = sqrt( 91) = 9.54 ft
