Calculate (A⃗ ×B⃗ )⋅C⃗ for the three vectors A⃗ with magnitude A = 5.08 and angle θA = 25.6 ∘ measured in the sense from the +x

alexgriva [62]

Answer:

(A⃗ ×B⃗ )⋅C⃗ = - 76.415

Step-by-step explanation:

First we need to calculate (A⃗ ×B⃗ ) :

(A⃗ ×B⃗ ) = A.B.sin (α).n

Where A is the magnitude of A⃗

Where B is the magnitude of B⃗

Where α is the angle between A⃗ and B⃗ = 63.9 - 25.6 = 38.3

Finally n is the vector orthogonal to A⃗ and B⃗

n magnitude is 1 and his direction is given by the right hand-rule

so n = ( 0 , 0 , 1 )

(A⃗ ×B⃗ ) = A.B.sin (α).n = 5.08 . 3.94 . sin (38.3) . (0 , 0 , 1 ) = (0,0,12.4)

C⃗ can be written as C.(0,0,-1) because of his +z - direction

C.(0,0,-1) = 6.16.(0,0,-1) = (0,0,-6.16)

(A⃗ ×B⃗ )⋅C⃗ = (0,0,12.4).(0,0,-6.16) = -76.41480787 = -76.415

What is the equation for y=3x+5

VLD [36.1K]

The graph of y = -3x+5

Step 1: Since the y - intercept is 5, plot the point (0,5).

Step 2: Since the slope is -3, move 1 unit to the right and 3 units down, so plot the point (1,2).

Step 3: Connect those points by a straight line.

A deck of 52 cards is shuffled. The first five cards of the deck are red. What is the probability that the last card in the deck

saveliy_v [14]

Answer:

The answer is " $\frac{1}{47}$ ".

Step-by-step explanation:

Although the five first players are red, the very first five cards are not spaded as the spad is a black card.

Its chance of the final card mostly on deck being the ace of spades is therefore determined as:

$= \frac{1}{\text{Number of remaining cards with the initial 5 cards}} \\\\= \frac{1}{47}$

Thus, $\frac{1}{47}$ here is the necessary chance.

Kerry purchased a used car for 14,4000. And had to pay 8% sales tax how much did she pay

saul85 [17]

Answer:

Kerry should pay = 155520

Step-by-step explanation:

Total amount paid = 14,4000 + 8% of 14,4000

It is given that,

Kerry purchased a used car for 14,4000. And had to pay 8% sales tax

<u>To find the 8% of 14,4000</u>

8% of 14,4000 = (8*144000)/100 = 11520

<u>To find total amount paid</u>

Total amount paid = 14,4000 + 8% of 14,4000

= 14,4000 + 11520 =155520

Therefore Kerry should pay = 155520
