Answer:
Fy=14.8N
Step-by-step explanation:
the dot product between and
is given by:
W=
this gives the equation :
26= (4.00)(-12.0)+(5.00)Fy
26= -48+(5.00)Fy
adding 48 to both sides of the equation:
74= (5.00)Fy
dividing by 5, we get
Fy=74/5.00=14.8
Answer:
-15
Step-by-step explanation:
Trust
They're complementary.
Complementary angles are a pair of two angles that add up to a sum of 90 degrees
Supplementary angles add up to 180 degrees
63 + 27 = 90
Let us compute first the probability of ending up an odd number when rolling a dice. A dice has faces with numbers 1 up to 6. The odd numbers within that is 3 (1, 3 and 5). Therefore, each dice has a probability of 3/6 or 1/2. Then, you use the repeated trials formula:
Probability = n!/r!(n-r)! * p^r * q^(n-r), where n is the number of tries (n=6), r is the number tries where you get an even number (r=0), p is the probability of having an even face and q is the probability of having an odd face.
Probability = 6!/0!(6!) * (1/2)^0 * (1/2)^6
Probability = 1/64
Therefore, the probability is 1/64 or 1.56%.
Answer:
Should be D.
Step-by-step explanation:
Because you can't factor the equation you use the quadratic formula. By using it you should get 4 plus or minus the square root of -4 all over 2. Simplified would be 2 plus or minus i
