A cylindrical tank with radius 5 m is being filled with water at a rate of 3 m3 ymin. How fast is the height of the water increasing

Answers

Answer 1

The rate at which the height of the water in this cylindrical tank is increasing is 26.18 m/mn.

How to calculate the volume of a cylinder?

Mathematically, the volume of a cylindrical tank can be calculated by using this formula:

V = πr²h

Where:

h is the height.r is the radius.

Differentiating with respect to h, we have:

dV/dt = πr²(dh/dt)

3 = 3.142 × 5² × dh/dt

3 = 78.55dh/dt

dh/dt = 78.55/3

dh/dt = 26.18 m/mn.

If (5+3i)(-2-4i)=a+bi, what is a+b for i=square root -1?
A. -48
B. -24
C. -20
D. -4

Answers

Answer:

B. -24

Explanation:

Step 1: Expand

[tex](5+3i)(-2-4i)[/tex] expands to [tex]-10 -20i -6i - 12i^2[/tex]

i is the square root of -1, so the [tex]i^2[/tex] will simplify further and make the equation:[tex]-10 -20i-6i+12[/tex].

This can be simplified because there are 2 constants, -10 and +12, as well as 2 coefficients to the same variable.

So, the equation becomes:

[tex]2-26i[/tex]

Step 2: Answer question

The question asks of you, what is a+b from the parent expression a+bi.

b is the coefficient that is linked with the variable i.

a has no variable, so it must be the constant.

Here, the value of the "b" coefficient is -26. And the value of the constant is positive 2.

So we have to plug these 2 values into the equation a+b:

[tex]2+(-26)[/tex]

This solves out as, -24

So, the answer to this question is B.

The value of a + b for i = square root -1 is -24 (Option B)

Data obtained from the question(5 + 3i)(-2 - 4i) = a + bii = √-1Value of a + b =?

How to determine the value of a + b

To determine the value of a + b, we'll begin by obtaining the value of a and b. This can be obtained as illustrated below

(5 + 3i)(-2 - 4i) = a + bi

Expand

5(-2 - 4i) + 3i(-2 - 4i) = a + bi

-10 - 20i - 6i - 12i² = a + bi

-10 - 26i - 12i² = a + bi

But

i = √-1

i² = -1

Thus, we have:

-10 - 26i - 12(-1) = a + bi

-10 - 26i + 12 = a + bi

-10 + 12 - 26i = a + bi

2 - 26i = a + bi

From the above,

a = 2b = -26

Therefore,

a + b = 2 + (-26)

a + b = 2 - 26

a + b = -24
