Which of the following best describes the algebraic expression x/6-1?

1 answer:

4 0

The option which best describes the algebraic expression x/6-1 is the last one - D. A number divided by six minus one.
A and B would mean that 6 is above the line, and x below it, which is not the case. C would mean that under the line it says x - 6, and not the other way round, which is why D is the correct answer.

15. The average speed that a tsunami (a large tidal wave) travels is represented

irina [24]

Correct question :

The average speed that a tsunami (a large tidal wave) travels is represented

by the function $s = (200d)^1^/^2$ where s is the speed (in miles per hour) that the tsunami is traveling and d is the average depth (in feet) of the wave.

a. Find the inverse of the function.

b. Find the average depth of the tsunami when the recorded speed of the wave is 250 miles per hour.

Answer:

a) $d = \frac{s^2}{200}$

b) 312.5 ft

Step-by-step explanation:

Given:

Average speeds, $s = (200d)^1^/^2$

a) To find the inverse of the function.

$s = (200d)^1^/^2$

s² = 200d

200d = s²

$d = \frac{s^2}{200}$

Therefore, inverse of the function =

$d = \frac{s^2}{200}$

b) average depth when speed is 250 miles per hour.

Average depth = d

Therefore, let's use the formula :

$d = \frac{s^2}{200}$

$= \frac{250^2}{200}$

$= \frac{62500}{200}$

d = 312.5 feet

The average depth when speed is 250 miles per hour is 312.5 ft

How many terms are in the arithmetic sequence 1313, 1616, 1919, ……, 7070, 7373?

Nataliya [291]

To find the number of terms in the arithmetic sequence, we need to use the formula
$a_{n}= a_{1}+(n-1)d$
where $a_{n}$ is the nth number, $a_{1}$ is the first number, n is the number of terms and d is the difference of the two consecutive numbers.
7373 = 1313 + (n - 1)(303)
7373 = 1313 + 303n - 303
7373 = 1010 + 303n
7373 - 1010 = 303n
6363 = 303n
6363 ÷ 303 = n
n = 21

Therefore, there are 21 terms in the arithmetic sequence given.
