Multiply corresponding components, then add the products:

Tan t /(sec t -cos t)= sin t/(cos t *(1/cos t -cos t))
=sin t/(cos t*(1-cos ²t)/cos t))
=sin t/sin² t=1/sin t [or=cosec t.]
There was 3 erasers in each pack because 2 times 3 is 6 plus 2 equals 8. so there are 3 in each pack.
Answer:
There is 1 solution
Step-by-step explanation:
y = -3 (x+1) ^2
Using the zero product property
0 = -3 (x+1) ^2
Divide by -3
0 = (x+1) ^2
Take the square root of each side
sqrt(0) = sqrt( (x+1) ^2)
0 = x+1
Subtract 1 from each side
-1 =x

Answer:
z = 4
Step-by-step explanation:
12z - 18 = 30
add 18 to both sides:
12z = 48
divide by 12:
z = 4
