Answer:

Your answer would be C because simplified:

5,600 is greater than 1,00

Step-by-step explanation:

Your answer wouldn't be A because simplified:

0.833 > 1.833 is an incorrect statement.

Your answer wouldn't be B because simplified:

4.243 > 5.875 is an incorrect statement.

Your answer WOULD be C because simplified:

5,600 > 1,000 is a true statement

Answer:

Step-by-step explanation:

You can reason your way through this without a calculator:

A: the absolute function turns everything positive, then you can see that 5/6 cannot be larger than 1 5/6

B: Realizing that √25=5, √18 cannot be larger than 5

C: 5.6x10³ means shifting to the left 3 positions: 5600 > 1000 so this one is true.

D: A negative number is always smaller than a positive number.

Find the coefficients of the terms below in the expansion of (uu+vv)8. Explain your reasoning.

gladu [14]

Answer:

Remember, the expansion of $(u+v)^n=\sum_{k=0}^n\binom{n}{k}u^{n-k}v^k$ .

Then,

$(u+v)^8=\sum_{k=0}^8\binom{8}{k}u^{8-k}v^k$

a) since $u^{8-k}=u^2$ , then $8-k=2, k=6$ . Therefore, the coefficient of $u^2v^6$ is $\binom{8}{6}=28$

b) $u^3v^5=u^{8-k}v^k$ . Then k=5 and the coefficient of the term is $\binom{8}{5}=56$

c) $u^4v^4$ , then k=4 and the coefficient of the term is $\binom{8}{4}=70$

Consider the algebraic expression --50 + 2a

lisabon 2012 [21]

Answer:

-45

Step-by-step explanation:

-50 + 2a represents the sum of the constant -50 and twice the value of the variable a.

If a = 2.5, then -50 + 2a has the value -50 + 2(2.5) = - 50 + 5 = -45.

Answer:

Step-by-step explanation:

x = 2n

2n + 2n + 2 + 2n + 4 + 2n + 6 + 2n + 8 = 80

10n = 60

n = 6

x = 12

12 + 14 + 16 + 18 + 20 = 80
