2. Suppose mZTOK = 49° .
vesna_86 [32]

Answer:

Part A: 41

Part B: 131

Step-by-step explanation:

PART A: Since a complementary angle is one that adds up to a total of 90 degrees the complement of 49 should be 41

90-49=41

PART B: Since a supplementary angle is one that adds up to a total of 180 degrees the supplement of 49 should be 131

180-49=131

Hope this helps!!! :)

16n2 – 10n – 5 = 6n<br> Solve the equation for all real solutions
sergiy2304 [10]

Answer:

n=5/4 or n=-1/4

Step-by-step explanation:

16n^2 - 10n-5=6n

16n^2-16n-5=0

(4n)^2-2.4n.2+2^2 = 2^2 + 5

(4n- 2)^2=9

4n-2 = 3 or 4n-2=-3

4n=5 or 4n=-1

n=5/4 or n = - 1/4

Particle travels along a circular path that has a radius of 3 feet. The angular velocity of the particle is 18 radians per minut
Gala2k [10]
We know that

[length of a circumference ]=2*pi*r
for r=3 ft

[length of a circumference ]=2*pi*3-----------> 18.84 ft

<span>The angular velocity of the particle is 18 radians per minute.

if 2pi radians  (full circle)------------------> 18.84 ft
18 radians----------------------------------> X
X=18*18.84/(2*pi)---------> X=54 ft
so
</span>The linear velocity of the particle is 54 ft/minute

the answer is
54 ft/min
