Which of these numbers below are exactly divisible by nine 107, 513, 944, 126, 802

Answers

513 and 126. You have to divide 9 by all the numbers, if the number is even then it is divisible.

Which of the following is a solution of z^5 = 1 + √3 i? 5√2 (cos150° + isin150°)
5√2 (cos156° + isin156°)
5√2 (cos174° + isin174°)
5√2 (cos204° + isin204°)

Please show me how to work it out.

Answers

Answer:

Option 2 is right

Step-by-step explanation:

Given that

$z^5=1+√(3) i$

We can write this in polar form with modulus and radius

$|z^5|= √(1+3) =2\ntan of Angle t =√(3) \n$

Hence angle = 60 degrees and

$|z^5|= 2(cos60+isin60)$

Since we have got 5 roots for z, we can write 60, 420, 780, etc. with periods of 360

Using Demoivre theorem we get 5th root would be

5th root of 2 multiplied by 1/5 th of 60, 420, 780,....

$z= \sqrt[5]{2} (cos12+isin12)\nz=\sqrt[5]{2} (cos84+isin84)\n\nz=\sqrt[5]{2} (cos156+isin156)\n\nz=\sqrt[5]{2} (cos228+isin228)\n\nz=\sqrt[5]{2} (cos300+isin300)\n$

Out of these only 2nd option suits our answer

Hence answer is Option 2.

Which of the following best defines density?A.
A measure of the volume of a given substance

B.
A number between 0 and 1 that defines how thick a substance is

C.
A measure of how much mass a given volume of a substance will have

D.
A measure of the mass of a given substance

Answers

Answer:

Density = mass/volume

Step-by-step explanation:

The mass per unit volume of a given substance is called its density. It can be represented by d or ρ. Mathematically, it is given by :

density=mass/volume

The SI unit of mass is kg and the SI unit of volume is m³. So, the SI unit of density is kg/m³.

So, the statement that defines density is "A measure of how much mass a given volume of a substance will have". Hence, the correct option is (c).

Density is mass per unit volume, therefore the correct answer is C. A measure of how much mass a given volume of a substance will have

-3=h+8 divided by 2 (HELP)

Answers

If whole right side divided by 2

-3=h+8 divided by 2
Divide right side 2
-3=h/2+4
Subtract 4 from both sides
-7=h/2
Multiply 2 on both sides
Final Answer: -3.5=h

If only the 8 is divided by 2

-3=h+8 divided by 2
Divide 8 by 2
-3=h+4
Subtract 4 from both sides
Final Answer: -7=h

If it is the answer of the left side divided by two the answer is -11/8. If it is 8 divided by then the answer is -7

suppose that you're building a shed and me to pour concrete slab to support it. You know that the slab will be 15 feet wide, 10 feet long, 6 inches deep. concrete is usually sold by the cubic yard. How many cubic yards of concrete will you need for the slab?

Answers

convert all to one unit - I'm choosing feet
15 x 10 x 0.5 = 15 x 5 = 75 feet
1 cubic yard = 1 yard x 1 yard x 1 yard = 3 ft x 3 ft x 3 ft = 27 feet?

75/27 = 2.77777778 cubic yards (I think)
