Answer:

Q6. x = 17
Q8. Yes, parallel
Q9. No, not parallel

Step-by-step explanation:

Q6. Solve for x

<u>Use ratios of similar sides</u>

28/(82 - 28) = (2x + 8)/(5x - 4)
28/54 = (2x + 8)/(5x - 4)
14/27 = (2x + 8)/(5x - 4)
14(5x - 4) = 27(2x + 8)
70x - 56 = 54x + 216
70x - 54x = 56 + 216
16x = 272
x = 272/16
x = 17

If ratios are same, the lines are parallel

41.8/33 = (102 - 45)/45
41.8/33 = 57/45
41.8*45 = 33*57
1881 = 1881

Yes, lines are parallel

38/19 = 52/24
2 = 2 1/3

Incorrect, lines are not parallel

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.

(-2,-1)(-1,2)(0,3)(1,4)(2,5) A: Function B: Not a function

kupik [55]

Answer:

This answer is a function because there are no repeating x values. It is okay if there are repeating y values, the x values are the problem. This one has no repeats though so it is a function!

Cotθ= tan30° find theta

scoundrel [369]

Answer:

Step-by-step explanation:

Cot is the same as 1/tan so:

$1/tan(theta) = tan(30)$

By rearranging the equation, we get:

$1/tan(30) = tan(theta)$

By taking the inverse tan, we get:

$theta = tan^-1 (1/tan(30)) =60$
