Answer:

20.s^{2} *7^{3}

21.4^{2} * b^{4}

22. 97.2

23. 234

Step-by-step explanation:

k^{4}*m\\ 3^{4} *\frac{5}{6}\\ 81*\frac{5}{6}=97.2

(c^{3}+ d^{4})^{2}  -(c+d)^3\\(-1^3+2^4)^2-(-1^3+2^3)\\-1+256+1+8\\=234

I hope this helps.

Suppose you conduct a test and your p-value turns out to be 0.08. what can you conclude?
drek231 [11]
When your p-value is greater than 0.05, we fail to reject the null hypothesis (the claim that there is no difference between the things being tested).  When we <em /><em>fail to reject</em> the null hypothesis, this means we DO NOT reject it, and that there is no statistical difference between the things in the test.

1 4/9 + 2 6/9 is equal to 4 1/9, true or false?
viktelen [127]

Answer: True

Explanation: To add mixed numbers, first add the fractions.

So here, we have 4/9 + 6/9 which is 10/9.

Then add the whole numbers.

So we have 1 + 2 which is 3.

So our answer is 3 and 10/9.

But notice, that since 10/9 is an improper fraction,

our answer is not in lowest terms.

10/9 can be rewritten as the mixed number 1 and 1/9.

So 3 and 10/9 is the same as 3 + 1 and 1/9 which is 4 and 1/9.

Since 4 and 1/9 is in lowest terms, this is our final answer.

So we can say that 1 and 4/9 + 2 and 6/9 is 4 and 1/9.

Or an angle θ with the point (−20, −21) on its terminating side, what is the value of cosine?
kherson [118]
Cos(θ) = -20/√((-20)^2 +(-21)^2)
.. = -20/-√841 . . . . . . . . . . . . . . . . . θ is a 4th-quadrant angle, so cos(θ) > 0
.. = 20/29

The value of the cosine is 20/29.
