1 answer:
Answer:
T(t) 
Step-by-step explanation:
To find the unit tangent vector for 
Unit Tangent Vector = 
Where
is the derivative of r(t) and
is its modulus.



Therefore, Unit Tangent Vector T(t)

The other angel is also equal to x and the sum of all angels need to be 360:
2x+90+26=360
2x=244
X=122
Answer:
d
Step-by-step explanation:
it's option d bro...becoz
x + 10 is the diameter
Easy
so remember
4 aces in a deck
probability =(desired outcomes)/(total possible)
total possible=52
4/52=1st card
then since he picked 1 out the total possible is and assuming he drwe an ace 3/51
so the answer is 4/52 times 3/51=1/221
Each ticket is 6.5 (divide 97.5 by 15), since we know this we can think of a number close to 13, such as 11, which gives you exactly 71.50
