0.8+7=-0.7k+1 what is the answer

1 answer:

6 0

After combining like terms:
-0.7k + 1 = 7.8
Subtract the 1 from both sides:
-0.7k = 6.8
Divide by -0.7 from both sides:
k = -9.7142, simplified is -9.7

Checked Answer:
-0.7(-9.7) = 6.79, simplified is 6.8

Use the cosine sum and difference identities to find the exact value. COS(5pi/12)

nydimaria [60]

5π/12 = (5 · 180°) : 12 = 75°
cos 75° = cos ( 45° + 30° )= cos 45° cos 30° - sin 45° sin 30° =
=√2/2 * √3/2 - √2/2 * 1/2 = $\frac{ \sqrt{6} }{4} - \frac{ \sqrt{2} }{4}= \frac{ \sqrt{6} - \sqrt{2} }{4}$
=(2.4495 - 1.4142): 4 = 0.258825
