Suppose sin(A) = 1/4. use the trig identity sin^2(A)+cos^2(A)=1 to find cos(A) in quadrant II. around to ten-thousandth.
larisa86 [58]

In quadrant II, \cos(A) will be negative. So

\sin^2(A) + \cos^2(A) = 1 \implies \cos(A) = -\sqrt{1 - \sin^2(A)} = -\dfrac{\sqrt{15}}4 \approx \boxed{-0.9682}

What are the first 5 terms of 4n+4,8n+3and 18-3n?Please?
dimulka [17.4K]
Assuming the first 5 terms are:

n = 0
n = 1
n = 2
n = 3
n = 4

a)  4n + 4
4(0) + 4 = 4
4(1) + 4 = 8
4(2) + 4 = 12
4(3) + 4 = 16
4(4) + 4 = 20

b)  8n + 3
8(0) + 3 = 3
8(1) + 3 = 11
8(2) + 3 = 19
8(3) + 3 = 27
8(4) + 3 = 35

c)  18 - 3n
18 - 3(0) = 18
18 - 3(1) = 15
18 - 3(2) = 12
18 - 3(3) = 9
18 - 3(4) = 6

Sean spends 35 minutes revising for his exam. Erica spends 1 hours 15 minutes revising for her exam. Work out the total time, in
Alja [10]

The total time spent in minutes is 110 minutes

<h3>How to determine the total time?</h3>

The given parameters are:

  • Erica = 1 hour, 15 minutes
  • Sean = 35 minutes

The total time is calculated as:

Total = Erica + Sean

So, we have:

Total = 1 hour, 15 minutes + 35 minutes

1 hour = 60 minutes

So, we have:

Total = 60 minutes + 15 minutes + 35 minutes

Evaluate the sum

Total = 110 minutes

Hence, the total time spent is 110 minutes
