Answer:

Here, V(r) is the function dependent on the variable r whch is the radius of any sphere.

By plugging different values of r in the formula. one can find the volume associated with it.

Here, V(r) represents the volume of the sphere when the radius is equal to r.

David wants to build a rectangular fencing with the 5 identical parts for his animals. He has 780 feet of fencing to make it. Wh

Vladimir79 [104]

Answer:

65 ft by 39 ft

Step-by-step explanation:

Let x ft be the length of each part and y ft be the width of each part. The total perimeter of all 5 parts is

$6x+10y=780$

The length of the large rectangle is 5y ft and the width of the large rectangle is x, so the total area is

$A=x\cdot 5y$

From the first equation,

$y=78-0.6x$

Substitute it into the area expression:

$A(x)=x\cdot 5(78-0.6x)=390x-3x^2$

Find the derivative:

$A'(x)=390-3\cdot 2x=390-6x$

Equate it to 0:

$390-6x=0\\ \\6x=390\\ \\x=65$

Then

$y=78-0.6\cdot 65=78-39=39$

Which equation represents a line that is parallel to y=-4x+3 and that passes through the point (-1, 2)?

belka [17]

A parallel line will have the same slope, which is -4. So the answer so far cannot be A or B.
Put x=-1 in each of C and D and we get y=2 for C and y=1 for D. Since the point is (-1,2) the answer is C.

(3×10 – 4)(2×1010) whats the scientific notion

Rudik [331]

The result of the multiplication in scientific notation is given by:

$6 \times 10^{6}$

<h3>What is scientific notation?</h3>

A number in scientific notation is given by:

$a \times 10^b$

With the base being $a \in [1, 10)$ .

When we multiply two numbers in scientific notation, we multiply the bases and add the exponents.

For this problem, the numbers are given by:

$3 \times 10^{-4}, 2 \times 10^{10}$

The result of the multiplication is given by:

$3 \times 10^{-4} \times 2 \times 10^{10} = 6 \times 10^{-4 + 10} = 6 \times 10^{6}$

The result of the multiplication in scientific notation is given by:

$6 \times 10^{6}$
