Answer:
452cm2
Step-by-step explanation:
surface area of sphere =4πr2
so 4π62 which equals to 452.39.
hope this helps u understand:)
Answer: 1/2 and 3/6
Explanation: 1/2 is equal to 3/6 because if you divide both 3 and 6 by 2 it’s 1/2
Not sure about 4
Answer: 0.500
Step-by-step explanation:
Given : A normal distribution has a mean
of 10 and a standard deviation
of 1.
Let x be a random variable that represents numbers .
The probability of selecting a number that is at most 10 will be

As the area occupied by standard normal curve less than equal to 0 = 0.500
So, required probability = 0.500
Answer:
54
Step-by-step explanation:
A tangent line makes a right angle with the radius to the point of tangency. Hence this triangle is a right triangle, and x° is the complement of 36°:
x° = 90° -36° = 54°
The value of x is 54.
Answer:
(−∞,4)
Step-by-step explanation:
Explanation:
To determine the interval that f(x) is increasing.
increasing when f'(x)>0f'(x)=−2(x−4)← using chain rule
solve −2(x−4)>0
⇒−2x+8>0
⇒x<4
interval is (−∞,4)
graph{-(x-4)^2-3 [-8.89, 8.89, -4.445, 4.44]}
