Answer:
x-490=t
Step-by-step explanation:
Marlee has x money
She deposited $60 meaning adding $60 to the bank
So x+60
THen Marlee need to withdraw $550 from her bank to rent
So the equation is now
x+60-550
60-550 is -490
Thus:
x-490
(I will represent (t) as the money she has left for the equation)
Thus the equation is
x-490=t
Hope this helps!
Answer: x = pi
sin²x - 2cos x - 2 = 0
⇔ 1 - cos²x - 2cos x - 2 = 0
⇔ cos²x + 2cos x + 1 = 0
⇔ (cos x + 1)² = 0
⇒ cos x + 1 = 0
⇔ cos x = -1
⇒ x = pi + k2pi
because 0 ≤ x < 2pi
=> x = pi
Step-by-step explanation:
There are four-thirds servings per pound
we are given
(a)
we can plug t=0
so, the height above the ground when the object is launched is 60 meter......Answer
(b)
we can set s(t)=0
and then we can solve for t
we can use quadratic formula
we get
..........Answer
(c)
we can find vertex
t=2.040816
now, we can plug it back
so, the maximum height is 80.408meter.........Answer
The outside of the quotient
