Answer:
a15 = 35
Step-by-step explanation:
Given:
a3 = 11
a6 = 17
Find:
a15 = ?
Computation:
a3 = 11 ⇒ a+ 2d = 11..........Eq1
a6 = 17 ⇒ a + 5d = 17...............Eq2
From Eq2 - Eq1
⇒ 3d = 6
⇒ d = 2
And a = 7
So,
⇒ a15 = a + 14d
⇒ a15 = 7 + 14 (2)
⇒ a15 = 7 + 28
⇒ a15 = 35
The answer would be 6. This be because 6 + -8 = -2.
Answer:
The approximate radian measure of the angle. So we have 15 nine 0.6 degrees convert degrees to radiance. You have to multiply by pi over 1 80. So if we did that, that'd be 59.6 pi over 1 80. So if we want to know the approximate value, we're going to use the pi button on our calculator to figure out what 59.6 times pi is. That's approximately 187.2389, Divided by 1 80. So now I would divide that number by 180 and that gives me 1.04 radiance, 1.04 radiance is the answer.
Answer:

Step-by-step explanation:
Let the time for which i bike is = x hours
Let the distance traveled in x hours = y miles
Ratio of distance and time will be = x : y
I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112
then the ratio of distance and time will be same in both the cases
So equation will be


Therefore, equation representing the proportional relationship will be

Step-by-step explanation:
x² + 20 = 2x
x² − 2x + 20 = 0
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-2) ± √((-2)² − 4(1)(20)) ] / 2(1)
x = [ 2 ± √(4 − 80) ] / 2
x = [ 2 ± √(-76) ] / 2
x = [ 2 ± 2i√19 ] / 2
x = 1 ± i√19
