This should not be in the elementary school section I didn't even learn about this....
Answer:
t0 = π/4
Step-by-step explanation:
The velocity v(t) = r'(t) = <-2sint,-2cost>
Since <1,-1>⊥v, <1,-1>•v=0. So,
(1)(-2sint) + (-1)(-2cost) = 0
cost - sint = 0
To figure this out you can do a proportion
34 X
---- = ------
55 100
Then you would cross multiply to get
55x=3400
Next you would divide 3400/55 which would come out to be 61.8181818 which would be your percentage 61.81%
Answer:
Step-by-step explanation:
A possible word problem for 3x+10 ≤75 could be
Mat has $75 dollars saved in his wallet and wants to use it for go carts. Knowing that the entrance to the park is $10, and each time around the go cart course is $3 what is the maximum times he can go around?
3x+10 ≤ 75, subtract 10 from both sides
3x ≤ 75-10, divide both sides by 3
x ≤ 65/3
or x ≤ 21.(6)
So it can go around 21 times the most.
Answer:
7/24
Step-by-step explanation:
1/8 + 1/6
First get a common denominator of 24
1/8 * 3/3 = 3/24
1/6 * 4/4 = 4/24
3/24 + 4/24 = 7/24
