.Instructions:Select the correct answer. The half-life of helium-5 is 7.6 × 10-22 seconds, and the half-life of helium-9 is 7 ×

Angelina_Jolie [31]

The half-life of helium-5 is 7.6 × 10^{-22} seconds, and the half-life of helium-9 is 7 × 10^{-21} seconds.

Approximately $\dfrac{7 \cdot 10^{-21}}{7.6\cdot 10^{-22}} = \dfrac{7}{7.6\cdot 10^{-1}} = \dfrac{7}{0.76} =9$ the half-life of helium-9 is greater than that of helium-5.
Answer: 9 times.

Kathy ran the 400-meter dash in 60.48 seconds. She ran the 200 meter dash in 28.9 seconds.If she divided her 400-meter dash time

nika2105 [10]

Answer:

Kathy would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.

Step-by-step explanation:

Kathy ran the 400-meter dash in 60.48 seconds, so if she now divided that time into 8 equal time segments we have:

$t = 60.48 s$

By dividing the above equation into 8:

$t = \frac{60.48 s}{8} = 7.56 s$

Hence, she would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.

I hope it helps you!

If dy/dx=2xy and y(0)=1. What is y(1) equal to?

Llana [10]

dy/dx = 2xy
dy/y = (2x)dx
INT(1/y)dy = INT(2x)dx
ln y + c = x^2 + d
ln y = x^2 + constant
y = e^(x^2 + constant)

1 = e^constant ... so constant=0 ... so y = e^(x^2)

Verification:

y = e^(x^2)
dy/dx = 2x*e^(x^2) = 2xy
and e^(0^2) = e^0 = 1
