Answer:

19 gram

Step-by-step explanation:

Formula of mass left after ionising: \frac{M}{2^{n} }  where M is original mass and n is half lives.

Using the equation:

\frac{150}{2^{3} } → 18.75

Therefore, 18.75 g left after ionising.

∵ If rounded to nearest gram then 19 gram.

Answer:

x = -9/4

Step-by-step explanation:

−2(x + 1/4) + 1 = 5 ​

Subtract 2 from both sides.

−2(x + 1/4) = 4 ​

Divide both sides by -2.

x + 1/4 = -2

Subtract 1/4 from both sides.

x = -2 1/4

x = -9/4

Choose the correct conic section to fit the equation.
yanalaym [24]

Answer:

Option A) Circle.

Step-by-step explanation:

We are given the equation:

(x - 3)^2 + (y - 12)^2 = 25

A general equation of the circle is of the form:

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center of the circle and r is the radius of circle.

Comparing the two equations, we get,

(h,k) = (3,12)\\r = \sqrt{25} = 5

Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.
