Answer:
3/10
Step-by-step explanation:
30 days out of 100. That is 30/100, which simplifies to 3/10.
Answer:
4 1/2 hours
Step-by-step explanation:
1 practice = 2 1/4 hours
2 practices = 4 1/2 hours
Answer: The zeroes of this function are x = 0 (which has a multiplicity of 1) and x = -3 (which has a multiplicity of 2) The graph of this function will be attached. Lastly, (-1, -4) is the local minima and (-3, 0) is the local maxima. I hope this has helped :)
First you check for Pythagoras' Theorem.
Is 8.6² = 8.1² + 2.6² ?
8.1² + 2.6² = 65.61 + 6.76 = 72.37
8.6² = 73.96
8.1² + 2.6² ≠ 8.6²
Since Pythagoras' Theorem is not satisfied it is not a right angled triangle.
The longest side is 8.6, let's find the angle facing the longest side 8.6.
By cosine formula CosA = (b² + c² - a²) / (2bc)
CosA = (2.6² + 8.1² - 8.6²) / (2*2.6*8.1) = -1.59/42.12 = -0.0377
A = Cos inverse (-0.0377) = 92.1 degrees
So there is an angle is greater than 90 degrees.
-41 I think u do distributive property
