Answer: -6.8

Step-by-step explanation:

the farther you go down, the less it is (because they're negative numbers) so you just keep counting line after line increasing by a tenth on each line and you eventually end up with -6.8!

Hope this helps! Good luck with your future work! <3

2. For the data set of Scientist Albert, find the ratio comparing reaction to product for all pairs of values in the table. Use
Kipish [7]
The answer is b. Notice that the problem is looking for the reaction to product ratio, which is tricky because it's easy to follow the order of the column and calculate the inverse of it. Check the first ratio, 0.3/2=0.15, we can immediately choose b out of the other 4 choices.

In the isosceles △ABC m∠ACB=120° and AD is an altitude to leg BC . What is the distance from D to base AB , if CD=4cm?
7nadin3 [17]

Correct answer is: distance from D to AB is 6cm

Solution:-

Let us assume E is the altitude drawn from D to AB.

Given that m∠ACB=120° and ABC is isosceles which means

m∠ABC=m∠BAC = \frac{180-120}{2}=30

And AC= BC

Let AC=BC=x

Then from ΔACD , cos(∠ACD) = \frac{DC}{AC} =\frac{4}{x}

Since DCB is a straight line m∠ACD+m∠ACB =180

                                              m∠ACD = 180-m∠ACB = 60

Hence cos(60)=\frac{4}{x}

          x=\frac{4}{cos60}= 8

Now let us consider ΔBDE, sin(∠DBE) = \frac{DE}{DB} =\frac{DE}{DA+AB} = \frac{DE}{4+8}

DE = 12sin(30) = 6cm
