13pi/12 lies between pi and 2pi, which means sin(13pi/12) < 0
Recall the double angle identity,
sin^2(x) = (1 - cos(2x))/2
If we let x = 13pi/12, then
sin(13pi/12) = - sqrt[(1 - cos(13pi/6))/2]
where we took the negative square root because we expect a negative value.
Now, because cosine has a period of 2pi, we have
cos(13pi/6) = cos(2pi + pi/6) = cos(pi/6) = sqrt[3]/2
Then
sin(13pi/12) = - sqrt[(1 - sqrt[3]/2)/2]
sin(13pi/12) = - sqrt[2 - sqrt[3]]/2
Answer:
$98100
Step-by-step explanation:
Using the given formula :
I = P × R × T
I = 90000 × 3/100 × 3
I = $8100
He saves = 8100 + 90000 = $98100
Answer: It's A.
You can see in the figure that:
BG=GD
<BGI=<OGD
GI=GO
If the exponent is a negative number, then you make it a fraction, with the exponent on top as a positive and the coefficient as a positive on the bottom AFTER you multiply, so what happens is if the coefficient has a negative exponent, you multiply the number by the exponent, make it positive, and put it under 1 as a fraction. So your answers are:
1/7
1/125
1/36
Hope this helps! Stay safe out there :)
