Answer:

You need to find the equations for each scenario and set them = to each other

Step-by-step explanation:

A) S = 5t + 5

B) S = 7t + 2

Now set them = and solve for t

5t + 5 = 7t + 2

3 = 2t

t = 3/2 of an hr

To check plug in 3/2 into both equations and you should get same answer.

Hope this helps and never stop striving to learn more!

3. Over what interval is the function decreasing?
vredina [299]

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.

In the arithmetic sequence {13, 6,-1,-8,...}, what is the common difference?
pav-90 [236]

════════ ∘◦❁◦∘ ════════

<h3>Answer = -7</h3>

════════════════════

<h3>Known</h3>

a = 13

U2 = 6

U3 = -1

U4 = -8

════════════════════

<h3>Question</h3>

d = ..?

════════════════════

<h3>Way to do </h3>

#since it gives a lot of number, i will just pick one of the nth term, ill choose U2

Un = a + (n-1)d

U2 = 13 + (2-1)d

6 = 13 + d

6 - 13 = d

d = -7

════════════════════

<h3>Note</h3>

• The formula of arithmetic sequence

<h2>Un = a + (n-1)d</h2>

n = nth term

a = first term

d = common difference
