Answer:
aₙ = 75 x 0.2ⁿ⁻¹ or 75 x (1/5)ⁿ⁻¹
Step-by-step explanation:
a₁ = 75
a₂ = 75 x 0.2¹ = 75 x 0.2 ²⁻¹ = 15
a₃ = 75 x 0.2² = 75 x 0.2³⁻¹ = 3
.......
aₙ = 75 x 0.2ⁿ⁻¹ or 75 x (1/5)ⁿ⁻¹
Answers:
Each yes/no answer refers to the question "is this a function?"
==================================
Explanation:
The last equation is not a function because of the even exponent over the y term. If you apply the fourth root to both sides, you'll end up with y = |x| and y = -|x| as the two possibilities. For any nonzero x, there are multiple y outputs.
The first three equations are functions because we don't have the same issue as the last equation. All exponents for the y terms are odd. Something like y without an exponent really means y^1.

Answer:
Yes she can.
Step-by-step explanation:
Val can make 6 slides in an hour.
1/6 * 60 minutes = 10 minutes. per slide
10 20 30 40 50 60 gives you six sldes, 1 every ten minutes.
=====================
In one hour, she can produce 6 slides.
In two hours, she can produce 12 slides (2 * 6 = 12)
Since she only needs 1 hour and 40 minutes to produce 10 slides, she is under her time limit of 2 hours.
