Strontium-90 has a half-life of 28.8 years. If you start with a 300-gram sample of strontium-90,
Kazeer [188]

Answer:  2.66 × 10⁻¹³

<u>Step-by-step explanation:</u>

First, use the decay formula   A=A_oe^{kt}   where

  • A is the final amount (amount left)
  • A₀ is the initial amount (amount you started with)
  • k is the rate of decay (you need to solve for this)
  • t is the time

Given:

  • A = 1/2(300) = 150
  • A₀ = 300
  • k = unknown
  • t = 28.8

150=300e^{28.8k}\\\\0.5=e^{28.8k}\\\\ln(0.5)=ln(e^{28.8k})\\\\ln(0.5)=28.8k\\\\\\\dfrac{ln(0.5)}{28.8}=k\\\\\\\large\boxed{-0.0240676=k}\\

Next, input the k-value and the new t-value to solve for A.

  • A = unknown
  • A₀ = 300
  • k = -0.0240676
  • t = 1440

A=300e^{1440(-.0240676)}\\\\\large\boxed{A=2.66\times 10^{-13}}\\

<em>Answer:</em>

∠WVR = 156

<em>Step-by-step explanation:</em>

Angles in a triangle add up to 180

∴ ∠SRT + RST + RTS = 180

∴ ∠SRT + 109 + 47 = 180

∠SRT = 24

Alternate Angle Theorem

∠SRT = 180 - ∠WVR

24 = 180 - ∠WVR

24 - 180 = - ∠WVR

-156 = - ∠WVR

∠WVR = 156

Have a beautiful day.

the coordinates of point t are ​(0,2). the midpoint of st is ​(1,-6) find the coordinates of point s.
sasho [114]

Question

the coordinates of point t are ​(0,2). the midpoint of st is ​(1,-6) find the coordinates of point s.

Answer:

(10,-14)

Step-by-step explanation:

0 + x

---------   = 5            Multiply both sides by 2 ---->   0 + x = 10  or x = 10

   2

2 + y

--------   = -8         Multiply both sides by 2  ---->  2 + y = -16   or y = -14        

   2

Therefore, the coordinates of point S should be at (10,-14)
