F’(x)= 1+3 square root x f(9)=68

Answer:

f(x) = x + 2x^\frac{3}{2} + 5

Step-by-step explanation:

I'm assuming the question here is asking for f(x)

The first step would be to find the antiderivative of f'(x)

\int{1+3\sqrt{x}} \, dx = \int{1 + 3x^\frac{1}{2}} dx

Apply the reverse power rule

x + 2x^\frac{3}{2} + C

Now solve for C when x = 9

x + 2x^\frac{3}{2} + C = 68\\9 + 2(9)^\frac{3}{2} + C = 68\\9 + 2(27) + C = 68\\9 + 54 + C = 68\\63 + C = 68\\C = 5

Now substitute into the antiderivative

f(x) = x + 2x^\frac{3}{2} + 5

Why is -7 an integer but not a natural number?
MrMuchimi

Answer:

Natural Numbers are basically "counting numbers". If I ask you to start counting, you'll start at 1, then 2, then 3, and so on. It doesn't include 0 or any negative numbers because you wouldn't start from -10 when asked to count.

In a company there are 33 male and 42 female staff. Calculate the percentage of male and female staffs
VMariaS [17]

Answer: 44%, 56%

Step-by-step explanation:

Given

A company has 33 males and 42 female staff

So, the total staff is the sum of male and female

\Rightarrow \text{Total=}33+42\\\Rightarrow \text{Total=}75

The percentage of male staff is

\Rightarrow \text{Male }\%=\dfrac{33}{75}\times 100\\\\\Rightarrow  \text{Male }\%=44\%

The percentage of female staff is

\Rightarrow \text{female }\%=\dfrac{42}{75}\times 100\\\\\Rightarrow  \text{female }\%=56\%

sphere a has radius 4 and a hemisphere b has a radius 8. fin the ratio of the volume of A to the volume of b
salantis [7]

Answer:

A/B = 0.125

Step-by-step explanation:

Givens

r for Sphere A = 4

r for Sphere B = 8

Solution

Volume A = 4/3 pi r^3

r = 4

Volume A = 4/3 pi 4^3

Volume A = 4/3 pi 64

Note: there is no point in expanding the result. 4/3 and pi are going to cancel out when you set up the volume formula

Volume B = 4/3 pi * r^3

r = 8

Volume B = 4/3 pi * 8^3

Volume B = 4/3 pi * 512

Ratio A to B = 4/3 pi * 64 / 4/3 * pi * 512        Cancel 4/3 pi

Ratio A to B = 64/512

Ratio A to B = 1/8

Ratio A to B = 0.125
