True or false 4400 is 10 times as much as 440

2 answers:

7 0

It's true: multiplying a number by 10 means to add an extra 0 at the end. So, if you multiply 440 by 10 you add an extra zero, and obtain 4400

The change in altitude of a bird after 2 __ 1 2 seconds was –41 __ 1 4 feet. What was the average change in altitude of the bird

svlad2 [7]

Answer:

$Average\ Change = -1\frac{7}{10} ft/s$

Step-by-step explanation:

Given

$Altitude\ Change = -4\frac{1}{4} \ ft$

$Time = 2\frac{1}{2}\ s$

Required

Determine the average change

This is calculated as follows:

$Average\ Change = \frac{Altitude\ Change}{Time}$

This gives:

$Average\ Change = \frac{-4\frac{1}{4}}{2\frac{1}{2}}$

$Average\ Change = -4\frac{1}{4}/2\frac{1}{2}$

Convert to improper fractions

$Average\ Change = -\frac{17}{4}/\frac{5}{2}$

Convert to multiplication

$Average\ Change = -\frac{17}{4}*\frac{2}{5}$

$Average\ Change = -\frac{17}{2}*\frac{1}{5}$

$Average\ Change = -\frac{17}{10}$

$Average\ Change = -1\frac{7}{10} ft/s$

What is the value of the 9th term in the following geometric sequence?

earnstyle [38]

Answer: The correct option is (D) 196608.

Step-by-step explanation: We are given to find the value of the 9th term in the following geometric sequence :

3, 12, 48, 192, . . .

We know that

the n-th term of a geometric sequence with first term a and common ratio r is given by

$a_n=ar^{n-1}.$

For the given sequence, we have

first term, a = 3 and the common ratio, r is given by

$r=\dfrac{12}{3}=\dfrac{48}{12}=\dfrac{192}{48}=~~.~~.~~.~~=4.$

Therefore, the 9th term of the given sequence will be

$a_9=ar^{9-1}=3\times 4^8=3\times65536=196608.$

Thus, the required 9th term of the given sequence is 196608.

Option (D) is CORRECT.
