Find the slope of a line that passes through the points (-5, 3) and (-3, 8)

Mathematics

Answer:

Slope: 5/2 or 2.5

Step-by-step explanation:

1. Put both of the y values together on the top of a fraction and the x values on the bottom.

It should look like this: \frac{8-3}{-3-(-5)}

2. Now you need to simplify the y and x values. -3-(-5) is equal to 2 and 8-3 is 5.

I should now look like this: \frac{5}{2}

3. That could be your answer as a fraction. Or you can take the extra step and  actually divide them. 5 divided by 2 is 2.5.

In the end, you will have a result of 5/2 or 2.5. That it the slope of the line of the points (-5,3) and (-3,8). I hope this helps and you actually understand it. Remember, don't cheat! Always do your best! Good luck!

Cesium-137 has a half-life of about 30 years. A) Find the annual decay rate and round final result to 4 decimal places. B) Find
MrMuchimi

Answer:

  • 0.0228
  • 0.0231
  • 100 years
  • 0

Step-by-step explanation:

The exponential equation for the fraction remaining after x years can be written as ...

  y = (1/2)^(x/30)

A) For x=1, the fraction remaining is ...

  y = (1/2)^(1/30) ≈ 0.97716 = 1 - 0.0228

Of the original amount, 0.0228 decays each year.

__

B) The continuous decay rate is the natural log of the growth factor, so is ...

  ln(0.97716) = -0.0231

The continuous decay rate is 0.0231 of the present amount (per year).

__

C) For y=.10 (1/10 of the original amount) we find x to be ...

  .1 = .5^(x/30)

  ln(.1) = (x/30)ln(.5) . . . . . take the natural log

  30ln(0.1)/ln(0.5) = x ≈ 100 . . . years

It will take 100 years for a 10-gram sample to decay to 1 gram.

__

D) As x goes to infinity, y goes to zero.

_____

The relationship between growth rate and growth factor is ...

  growth factor = 1 + growth rate

When the growth rate is negative, it is called a decay rate.

A rectangular tile has a thin diagonal line drawn in its design. The longer dimension of the tile is 12 inches. The angle formed
tatuchka [14]

Answer: 32 inches


Step-by-step explanation:

Since all the interior angles in a rectangle are right angles.

Therefore, the triangle which is formed by the diagonal and the shorter side of the tile with the longer side will be right triangle.

By trigonometry, in right triangle

\tan{\theta}=\frac{\text{side opposite to }\theta}{\text{side adjacent to }\theta}

let x be the smaller side.

Therefore,

\tan72^{\circ}=\frac{12}{x}\\\Rightarrow\ 3.077683=\frac{12}{x}\\\Rightarrow\ x=12\times3.077683\\\Rightarrow\ x=3.89903703533\approx4\ inches

The perimeter of the rectangular tile= 2(12+4)=2(16)=32\ inches
