Three days,
1 1/4 = 5/4  
1/2= 2/4
2/4+1/4= 3/4 the first day
5/4-3/4= 2/4 
2/4 = 1/4 and 1/4 = two days
the first day+ two days= 3 days

Find the parametric equations for the line that is tangent to the given curve at the given parameter (3cost)i (t^4 -3sint)j
ale4655 [162]

Answer:

Following are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attached file.

In the given equation, when the point t=0

So,

\to r(0) = (3 \cos 0)i + (0^4 - 6 \sin 0)j + (2e^{3\times 0})k)

           = (3 \times 1)i + (0 - 0)j + (2e^{0})k)\\\\ = 3i +  0j + (2 \times 1)k)\\\\ = 3i +  0j + 2k \\

The value of the coordinates are 3, 0, 2 . so, the equation of the line is:

\to \frac{(x-3)}{3 \cos \ t} = \frac{(y-0)}{(t^{4}-6 \sin \ t)} = \frac{(z-2)}{2e^{3t}}=k

The top two answers are equivalent, while the bottom one is not. You would use distributive property in the parentheses. If both expressions are the same, they are equivalent

Determine the rate and the unit rate. $279 for 9 tickets. $18 for 6 volleyballs. 4 fouls in 20 minutes. 36 strikeouts in 54 inni
sergejj [24]
<span>The rate is the ratio and the unit rate is the rate when the denominator is 1.


$279 for 9 tickets.

=> rate = $279 / 9 tickets => unit rate = $ 31/ ticket

 $18 for 6 volleyballs.

=> rate = $ 18 / 6 volleyballs =>  unit rate = $ 3 / volleyball

4 fouls in 20 minutes.

=> rate = 4 fouls / 20 minutes => unit rate = 0.2 fouls / minute

36 strikeouts in 54 innings.

=> rate = 36 strikeouts / 54 innings => unit rate = 0.67 strikeouts / inning
