Answer:

Step-by-step explanation:

Given

y = 3x + 2

Comparing with y = mx + c

The slope in the problem, 'y=3x+2' is 3.

The number next to the x in these equations is always the slope.

You essentially have four triangles. The area of a triangle is: A=bh/2 (b=base length and h=height)

So the area is simply the sum of the four triangle areas...

A=(3*2)/2+(3*2)/2+(7*2)/2+(7*2)/2

A=20 ft^2

A 30 gram sample of a substance that's used to sterilize surgical instruments has a k-value of 0.1235. Find the substances half

jok3333 [9.3K]

Answer : The substances half life in days is, 5.6 days.

Step-by-step explanation :

Half life : It is defined as the amount of time taken by a radioactive material to decay to half of its original value.

All radioactive decays follow first order kinetics.

The relation between the half-life and rate constant is:

$k=\frac{0.693}{t_{1/2}}$

where,

k = rate constant = 0.1235 per days

$t_{1/2}$ = half-life

Now put all the given values in the above formula, we get:

$0.1235\text {days}^{-1}=\frac{0.693}{t_{1/2}}$

$t_{1/2}=5.6\text{ days}$

Thus, the substances half life in days is, 5.6 days.
