The plutonium isotope has half life

Mathematics
1 answer:
ratelena [41]2 years ago
6 0

Answer:

Step-by-step explanation:

The different isotopes have different "half-lives" – the time it takes to lose half of its radioactivity. Pu-239 has a half-life of 24,100 years and Pu-241's half-life is 14.4 years. Substances with shorter half-lives decay more quickly than those with longer half-lives, so they emit more energetic radioactivity.

What is the slope-intercept form for a line that passes through (4,3) and is parallel to x=0
nikitadnepr [17]

Answer:

x=4

Step-by-step explanation:

x=0 is an undefined slope(straight line vertically)

We need the line to pass through the point (4,3)

So, we just take the x coordinate from the equation and make it also have an undefined slope.

x = 4

thank you for hurrying here is the very last one Explain how you would find the perimeter of this triangle.
Lena [83]

Step-by-step explanation:

Use the method of TOA CAH SOH.

tan(51.3) =  \frac{opp}{adj}  \\  \tan(51.3)  =  \frac{u}{4}  \\ u = 4 \tan(51.3)

cos(51.3)  =  \frac{adj}{hypo}  \\  \cos(51.3)  =  \frac{4}{v}  \\ v \cos(51.3)  = 4 \\ v =  \frac{4}{ \cos(51.3) }

Perimeter of triangle = Sum of all sides =

u \:  +  \: v + 4
