1. To solve this problem and calculate the value of <span> "x" when "y" is 14.4, you must apply the following formulla:
 
 y=k/x
 
 k: </span> It is the constant of variation or constant of proportionality.
 
 2. So, keeping this on mind, you must calculate the value o the constant of variation "k", with the values given in the problem. Then, you have:
 
 k=yx
 k=(6)(12)
 k=32
 
 3. Now, you can apply the equation y=k/x and clear the "x" to find its value:
 
 yx=k
 x=k/y
 
 k=32
 y=14.4
 
 4. Then, you have:
 
 x=32/14.4
 
 5. Therefore, the answer is:
 
 x=2.22

90. The measure of an inscribed angle is half of that of the measure of its arc, and the measure of the angle corresponding with arc a is 45. 45*2 is 90, so 90 is the measure of arc a.

I don't know how to answer the top two and I don't know if the bottom one is correct, help me please
Tpy6a [65]
1) How many 3/4 does it take to make 9/2?


     Now look at this, 3/4 x 6 = 4 1/2.  4 1/2 is the same as 9/2


   3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 ---> takes 6, 3/4's to make 9/2

2)  How many 3/4's go into 9/2?


    This is the same question as the 1st one so the answer is 6 :)


3)  9/2 divided by 3/4 = ??


         Use the KEEP< CHANGE< FLIP method, so it turns into  I
                                                                                                    I
                                                                                                    I
                                                                                                    I
      9/2 x 4/3                       < -------------------------------------          I


  This is equal to 36/6 which is 6 :)


The answer is 6 for numbers 1, 2, and 3 :)

Pikachu claims that you can use the method of undetermined coefficients fo solve the following. y" - y' -12y = g(t) where g(t) a
Tom [10]

Pikachu is right.

Undetermined Coefficients (that we learn here) only work when f(x) is a polynomial, exponential, sine, cosine, or a linear combination of those.

And,

As we can see that the equation given is a Polynomial,

So, Pikachu is right.

The side lengths 30, 41, and 70 can form a triangle.
True [87]
A = 30
B = 41
C = 70

A < B + C
30 < 41+70 ==> 30 < 111 (TRUE)

B < A + C ==>
41 < 30 + 70 ==> 41 < 100 (TRUE)

C < A+B
70 < 30 + 41 ==> 70 < 71 (TRUE)

Yes, can!

Porsha calculates the amount of money she will have at the end of 6 years on a $5,000 investment earning 3.75% interest compound
OLEGan [10]
Porsha` s expression:
5,000 ( 1 + 0.0375 ) ^24
A = P * ( 1 + i  ) ^n
n = 6 * 4 = 24
i = 0.0375 : 4 = 0.009375
Porsha`s expression is wrong. True expression is:
5,000 * ( 1 + 0.009375 ) ^24
Answer: B ) Porsha`s expression should have 1 + 0.009375 in the parentheses.
