Arturiano [62]

Answer:

4y = -3x - 48

Step-by-step explanation:

y - y1 = m(x - x1)

y1 = -9 x1= -4 m = -3/4

y -(-9) = -3/4(x -(-4)

y + 9 = -3/4(x + 4)

y + 9 = -3/4x -12/4

multiply through by 4

4y + 36 = -3x -12

4y = -3x -12-36

4y = -3x -48 in the form y = mx + c

Ivan

Answer:

693 Years

Step-by-step explanation:

Given an initial amount A_o and k (a negative constant) determined by the nature of the material, the amount of radioactive material remaining at a given time​ t, is determined using he formula:

A(t)= A_oe^{kt}

If a certain radioactive isotope decays at a rate of 0.1​% annually.

\frac{1}{2} A_o= A_oe^{-0.001t}\\e^{-0.001t}=\frac{1}{2}\\$Take the natural logarithm of both sides\\-0.001t=ln(0.5)\\t=ln(0.5) \div -0.001\\t=693.15\approx 693 \:years

The half-life of the isotope is 693 years.

Help please!! :((((((((!!!!!!!!!
AlekseyPX
Look back at the rules of exponents. 

(a^n)^d = a^(n×d) 

Therefore, 
(17^1/7)^7 
=17^(1/7×7) 
=17^(7/7) 
=17^1 or 17 

Hope I helped :)
