Judy got 8 toothbrushes. You can get this answer by setting $10.48= to $1.31x. X being the variable representing how many toothbrushes she brought. And the solve for x by dividing 10.48 by 1.31 to get 8

State one form of the Law of Cosines and provide a trick for writing the other two forms and explain when Law of Cosines should

Yuki888 [10]

Solving for Angles

$\displaystyle \frac{a^2 + b^2 - c^2}{2ab} = cos∠C \\ \frac{a^2 - b^2 + c^2}{2ac} = cos∠B \\ \frac{-a^2 + b^2 + c^2}{2bc} = cos∠A$

* Do not forget to use the inverse function towards the end, or elce you will throw your answer off!

Solving for Edges

$\displaystyle b^2 + a^2 - 2ba\:cos∠C = c^2 \\ c^2 + a^2 - 2ca\:cos∠B = b^2 \\ c^2 + b^2 - 2cb\:cos∠A = a^2$

You would use this law under two conditions:

One angle and two edges defined, while trying to solve for the third edge
ALL three edges defined

* Just make sure to use the inverse function towards the end, or elce you will throw your answer off!

_____________________________________________

Now, JUST IN CASE, you would use the Law of Sines under three conditions:

Two angles and one edge defined, while trying to solve for the second edge
One angle and two edges defined, while trying to solve for the second angle
ALL three angles defined [of which does not occur very often, but it all refers back to the first bullet]

* I HIGHLY suggest you keep note of all of this significant information. You will need it going into the future.

I am delighted to assist you at any time.

Choose the definition for the function.

Answer:

It is either A or B. I am not certain only because I do not know if your assignement is indicating that the underlined greater sign represents an open dot or a closed dot

Arrange the slopes from flattest to steepest. -3/2, 0, 4/3, undefined

Dovator [93]

To arrange the slopes we need to take their absolute values.
1. Undefined slope means a vertical line, so it is going to be steepest.
2.|4/3| = 4/3
3.|-3/2| = 3/2
4. 0 means horizontal line.

From flattest to steepest: 0, -3/2, 4/3, undefined.

there are 225 wolves in a state park the population is increasing at the rate of 15% per year you want to make a prediction for

erastova [34]

Well, here is how i would do it.

We start with 225, at a rate of 15% per year. Assuming your answers are in years and not months, we will increase by this increment; years.

So, we start with 225, and a 15%, or .15, increase. So what we would do, it take 225 times .15. One way ive learned to do this (via algebra class) is that you can times it by 1.15 to make it quicker, this just takes out the adding step.

So after one year, we would have a total of 258.75, or about 259 wolves.

after two years, we would have about 298 (we cant have a half of a wolf!)

after 3 years, we would have about 343 wolves.

after 4 years, we would have about 394 ish

after 5 years, we would have about 453

after 6 years, we would have about 521.

So, it would take about 5 and a half years, if thats an option choice.

A man 6'2" tall Casts a 9'3" shadow how tall is a child that casts a 5'4" shadow at the same time of the day .To the nearest who

ahrayia [7]

Add 3.1 to 5.4.

The example provided shows that the shadow casted is 3.1 more than the man's actual. since it says round the nearest whole number add only 3

so: 5.4+3=8.4

That's the best I have

Hopefully this helps
