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.

iragen [17]

Answer:

B.) 27ft

Step-by-step explanation:

The labeled points given: (5,18) and (1.5, 7.5)

Slope = (18 - 7.5)/(5-1.5) = 10.5 / 3.5 = 3

A linear model:

y - 18 = 3(x - 5)

y - 18 = 3x - 15

y = 3x + 3

If x = 8 seconds then the distance in feet (y) would be: (plug in x = 8 into the equation y = 3x + 3)

y = 3(8) + 3

y = 24 + 3

y = 27 ft

Answer:

B.) 27ft

Which relation represents a function?
Airida [17]
<h3>Answer: Choice C</h3><h3>{ (-2,2), (0,2), (7,2), (11,2) }</h3>

Here we don't have any repeated x values.

In choice A, x = 2 repeats. In other words, x = 2 leads to multiple y outputs. So this is not a function. Choices B and D are similar stories. A function is only possible if every x leads to exactly one y value only. The graph must pass the vertical line test.

Side note: the y values can repeat, but the function won't be one-to-one.
