Please help, will grant brainliest if correct, need now!!
Mama L [17]

Answer:

- 7

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ - 5, - 2 ]

f(b) = f(- 2) = (- 2)² - 4 = 4 - 4 = 0

f(a) = f(- 5) = (- 5)² - 4 = 25 - 4 = 21, thus

average rate of change = \frac{0-21}{-2-(-5)} = \frac{-21}{3} = - 7

Scott divides some 4-digit numbers by 1000. His answer is a decimal every time. Scott says,if you divide a 4-digit number number
Ghella [55]

Answer:

1000, 2000, 3000, .... etc are the 4-digit numbers which when divided by 1000, give whole number answer.

Step-by-step explanation:

Scott divides some 4- digit numbers by 1000 and his answer is a decimal every time.  

From this Scott has concluded that if you divide a 4-digit number by 1000, then the answer will never be a whole number.

I think Scott is wrong and the reason is that if we try to divide those 4-digit numbers which are multiples of 1000, i.e. 1000, 2000, 3000, 4000, ... etc. with 1000 then only you will get a whole number answer. (Answer)

Schach [20]

Answer:

2 RootIndex 4 StartRoot 4 EndRoot

64^{\frac{1}{4}}

Decompose the number 64 in prime factors

64=2^{6}=2^{4}2^{2}

substitute

64^{\frac{1}{4}}=(2^{4}2^{2})^{\frac{1}{4}}=2^{\frac{4}{4}}2^{\frac{2}{4}}=2\sqrt[4]{4}
