Answer: Correct answer is 1st option , 12.3


Step-by-step explanation:


We can find the value of x by calculating the tangent of the angle 39.


We know, that tangent of an angle in a triangle = Perpendicular/Base, corresponding to that angle.


So, tan 39 = 10/x


Again, we know that tan 39 = .81


So, .81 = 10/ x

or, x = 10/.81

or, x = 12.34


So value of x to the nearest tenth = 12.3


Hope thsi helps


Thank you

How much chromium-51 will be left after 7 months?
Makovka662 [10]

Answer:

It seems there's more information in you question that you haven't posted.

7 months = 7 * (365/12) = 213 days

The half-life of chromium 51 is 27.7 days.

After 7 months, chromium 51 will have undergone 7.69 half-lives.

To solve for the ending amount we'll use the formula:

Ending Amount = Beginning Amount / 2^n where 'n' = # of half-lives

We'll say the beginning amount =1

Ending Amount = 1 / 2^7.69

Ending Amount = 0.0048426082

Basicaly if you started with 1 gram of chromium 51, after 7 months you would have 0.0048426082 grams.

Step-by-step explanation:

j^2 -2j -24 =0

Factor

What 2 numbers multiply to -24 and add to -2

-6*4 = -24

-6+4 = -2

(j-6) (j+4) =0

Using the zero product property

j-6 =0     j+4 =0

j =6            j=-4
