This exercise uses the radioactive decay model The burial cloth of an Egyptian mummy is estimated to contain 60% of the carbon-14 it contained originally. How long ago was the mummy buried? (The half-life of carbon- 14 is 5730 years. Round your answer to the nearest ten years.)

Answers

Answer:

4257 years

Step-by-step explanation:

Given that:

Half-life of carbon 14 (t1/2) = 5730

Estimated carbon 14 content = 60% of amount of carbon 14 = 0.6

Using the model :

m(t) = mo*e^-rt

Decay rate (r) = In2/t1/2 = 0.00012

mo = initial mass

Hence,

Mass of carbon 14 in mummy m(t) = 0.6mo

0.6mo = mo*e^-(0.00012 * t)

0.6 = e^-(0.00012 * t)

Take the ln of both sides

In(0.6) = - 0.00012t

−0.510825 = - 0.00012t

t = 0.510825 / 0.00012

t = 4256.875

t = 4257 (nearest whole number)

In ΔXYZ, the measure of ∠Z=90°, ZY = 4, XZ = 3, and YX = 5. What ratio represents the tangent of ∠X?

Answers

Answer:

[tex]tan\ X= \frac{4}{3}[/tex]

Step-by-step explanation:

Given

[tex]Z=90\°[/tex]

[tex]ZY = 4[/tex]

[tex]XZ = 3[/tex]

[tex]YX = 5[/tex]

Required

Determine tan x

This question can be illustrated using the attached image

Tan of an angle is calculated as:

[tex]tan \theta = \frac{Opposite}{Adjacent}[/tex]

In this case, it is:

[tex]tan\ X= \frac{ZY}{XZ}[/tex]

Substitute values for ZY and XZ

[tex]tan\ X= \frac{4}{3}[/tex]

Hence, the required ratio is 4/3

Answer:

4/3

What value of x is in the solution set of 9(2x + 1) < 9x - 18?

A. -4

B. -3

C. -2

D. -1

Answers

Answer:

b. -3

Step-by-step explanation:

9(2x+1) < 9x-18

(distribute the 9)

18x+9 <9x-18

(subtract 9 from both sides)

18x<9x-27

(subtract 9x from both sides)

9x<-27

(divide both sides by 9)

x<-3

Triangle D is different.

Every triangle is right-angled except for triangle D.

Proof for the 3rd angle of triangle D:

150+x = 180

x = 30

Therefore, we can prove that there are no right angles in triangle D.

Let x = 2 + 8i and xy = –2 + 26i. What is y?

Answer: 3+i

Answers

Answer:

3 + i

Step-by-step explanation:

The solution for the complex function is equal to y = 3 + i.

What is a complex function?

The function which is made up of the real numbers, as well as imaginary numbers, are called complex numbers these numbers are represented by a +ib form where the first part is the real part and the second part is the imaginary form.

The given complex functions are x = 2 + 8i and xy is -2+ 26i. The value of y will be calculated as below:-

xy = -2+ 26i.

y = ( -2+ 26i ) / x

y =  ( -2+ 26i ) / ( 2 + 8i )

The value of the function will be calculated by rationalizing the function. When p and q are integers and q is not equal to zero, a result is a rational number, which has the form p/q. This ratio is between two integers.

The fundamental distinction between a fraction and a rational number is that fractions are always positive while rational numbers can be either positive or negative.

[tex]y =\dfrac{-2+26i}{2+8i} = \dfrac{-1+3i}{1+4i}[/tex]

[tex]y =\dfrac{-1+3i}{1+4i}\times \dfrac{1-4i}{1-4i}[/tex]

[tex]y = \dfrac{-1+4i+13i+52}{1+16}[/tex]

[tex]y = \dfrac{17i+51}{17}[/tex]

y = 3+i

Therefore, the solution for the complex function is equal to y = 3 + i.
