Answer: a = 8
Step-by-step explanation:
use the equation a^2 + b^2 = c^2
c = 17, b = 15
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 64
a = 8
The probability of spinning a red is 2/5
<h3>Probability</h3>
Probability is the likelihood or chance that an event will occur
- Probability = Expected/Total outcome
Given the following information
- Total number of spin = 30 spin
- Number of times it lands on red = 12 times
Pr(spinning a red) = 12/30
Pr(spinning a red) = 2/5
Hence the probability of spinning a red is 2/5

Hello here is a solution :
f'(x) =( sin11x)'cos11x +<span>sin11x(cos11x)'
(sin(ax+b))'=a cos(ax+b)
</span>(cos(ax+b))'=-a sin(ax+b)
f'(x) = 11 cos11xcos11x-11sin11xsin11x
f'(x) = 11(cos11x)²-11(sin11x)²
