Answer:
20 are purple.
Step-by-step explanation:
4/6 * 30
= 120/6
= 20.
1/2 = cos(2*t)sqrt(3) /2 = sin(-2*t)find tfind the time derivative of x(t), y(t)(-2sin(2*t) , -2cos(2*t) )plug in the t you found to find the velocity vector.
Answer:

Step-by-step explanation:
Give me brainllest
in STR,
ST=SR
therefore, t=r(angles opposite equal sides of a triangle are equal)
T=73
C+73+73=180(ASP of triangle)
C=34
Use the formula for the sum of a geometric sequence:
Sum = (a(r^n - 1))/(r - 1)
where a is the first term, -3
r is the common ratio, -2
and n is the number of terms
Thus,
Sum = ((-3)((-2)^10 - 1))/(-2-1) = 1023
