Answer:

x=1 or x= 1/2

Step-by-step explanation:

Given equation is:

(2x-2)(8x-4)=0

we have to find the value of x.

The Zero-Product Property states that

If x.y=0 then x=0 or y=0 or both.

Apply The Zero-Product Property to the given equation.

(2x-2)(8x-4)=0

2x-2=0 or 8x-4=0

First solve 2x-2=0

Adding 2 to both sides of above equation,we get

2x-2+2=0+2

2x+0=2

2x=2

Dividing by 2 to both sides of above equation,we get

2x/2=2/2

x=1

Now, solve 8x-4=0

Adding 4 to both sides of above equation,we get

8x-4+4=0+4

8x=4

Dividing by 8 to both sides of above equation,we get

8x/8=4/8

x=1/2

Hence,the solution is x=1 or x=1/2.

Answer:

The final answers are x = 1 or x = 1/2.

Step-by-step explanation:

Given the equation is (2x - 2)(8x - 4) = 0.

The Zero-Product property says "if a*b=0, then a=0 or b=0 or both."

we have (2x - 2)(8x - 4) = 0.

It means (2x-2) = 0 or (8x-4) = 0.

2x = 2 or 8x = 4.

x = 2/2 or x = 4/8.

x = 1 or x = 1/2.

So, final answers are x = 1 or x = 1/2.

The amount y (in grams) of the radioactive isotope fermium-253 remaining after t hours is y=a(0.5)t/72, where a is the initial a

almond37 [142]

Answer:

Per hour decay of the isotope is 0.96%.

Step-by-step explanation:

Amount of radioactive element remaining after t hours is represented by

$y=a(0.5)^{\frac{t}{72}}$

where a = initial amount

t = duration of decay (in hours)

Amount remaining after 1 hour will be,

$y=a(0.5)^{\frac{1}{72} }$

y = 0.9904a

So amount of decay in one hour = a - 0.9904a

= 0.0096a gms

Percentage decay every hour = $\frac{\text{Amount of decay}}{\text{Initial amount}}\times 100$

= $\frac{0.0096a}{a}\times 100$

= 0.958 %

≈ 0.96 %

Therefore, per hour decay of the radioactive isotope is 0.96%.
