A coconut is a fruit that is made up of a hard outer shell that is spherical. Inside, there is a thick layer of coconut meat
Ivenika [448]

Answer:  There is room for

approximately 33.49 in^3 of coconut milk.

Step-by-step explanation:

Hi, we have to calculate the volume of milk inside the coconut:

First, we have to find the diameter of that volume that is equal to the diameter of the entire coconut minus the thickness of the coconut meat:

5-1 = 4 in (diameter)

Now, we simply have to apply the next formula:  

Volume of a sphere: 4/3 π radius^3

Since: radius = diameter /2

V = 4/3 π (d/2)^3

Replacing with the values given:

V = 4/3 (3.14) ( 4/2)^3 = 33.49 in3

Feel free to ask for more if needed or if you did not understand something.

Which of the following represents x = 1/3y written in general form?
babunello [35]

The general form of the given equation is 3x-y=0.

The given equation is x=\frac{1}{3}y.

We need to write the given equation in a general form.

<h3>What is a general form of an equation?</h3>

The general form of any equation contains the degree of variables in decreasing order. The general form of a linear equation is ax + b = 0.

That is, 3x=y

3x-y=0.

Hence, the general form of the given equation is 3x-y=0.

For f(x) = 2x + 1 and g(x) = x^2- 7, find (f - g)(x). ?
Irina18 [472]

Answer:

(f-g)(x)=-x^(2)+2x+8

the solutions are:

<em><u>x=4 or x=-2</u></em>

Step-by-step explanation:

(f-g)(x)=2x+1-(x^(2)-7)

(f-g)(x)=-x^(2)+2x+1+7

(f-g)(x)=-x^(2)+2x+8

does this help or should I solve for the zeros/solutions of this quadratic equation?

then:

-x^(2)+2x+8=0

-(x^(2)-2x-8)=0

x^(2)-2x-8=0

(x-4)(x+2)=0

<em><u>x=4 or x=-2</u></em>

Use the binomial expression (p+q)^n to calculate a binomial distribution with n=5 and p=0.3.(Show all steps)
Helen [10]

Answer:

The binomial in expanded form is (0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}.

Step-by-step explanation:

The Binomial Theorem states that a binomial of the form (a + b)^{n} can be expanded by using the following identity:

(a + b)^{n} = \Sigma \limits^{n}_{k = 0}\,\frac{n!}{k!\cdot (n-k)!}\cdot a^{n-k}\cdot b^{k} (1)

If we know that a = p = 0.3 and n = 5, then the expanded form of the binomial is:

(p+q)^{n} = \frac{243}{100000} + 5\cdot \left(\frac{81}{10000} \right)\cdot q + 10\cdot \left(\frac{27}{1000})\cdot q^{2} + 10\cdot \left(\frac{9}{100} \right)\cdot q^{3} + 5\cdot \left(\frac{3}{10} \right)\cdot q^{4} + q^{5}

(0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}
