Answer and Explanation:
Number of classes = 8
Highest value =2300
Lowest value = 1250
Class width= highest value – lowest value / number of classes
= 2300 – 1250/8
= 131.25 = 132
So, we can write class as 1250+132=1382
Class frequency
1250-1382 2
1382-1514 3
1514-1646 6
1646-1778 2
1778-1910 3
1910-2042 2
2042-2174 1
2174-2306 1
Answer:
It is increasing when x < 1
Step-by-step explanation:
If you substitute x = 1 in the equation you get that y = 10 at that point which is the maximum point at which graph reaches in the y direction. As you can see, the slope of the derivative is increasing, which means that the slope of the tangent line is increasing before that point.
Hope this helps
Hi there!
The answer is:
We can find this answer by writing the factors.
Now we can see that the terms that are in common are 3 and p. Therefore, the GCF is 3p.
Answer:
Surface area of cylinder= 211.5π
Step-by-step explanation:
Given,
Height of cylinder = 19cm
Diameter of cylinder = 9cm
i.e Radius of cylinder = diameter/2 = 9/2 = 4.5cm
Surface area of cylinder = 2πrh + 2πr²
Plug corresponding values of r and h in surface are formula.
Surface area of cylinder = 2πrh + 2πr² = 2π*4.5*19 + 2π*4.5²
Surface area of cylinder = 171π+40.5π = 211.5π
Hence we get surface area of cylinder= 211.5π
