Time (sec): 2
a) What is the amplitude of the waves? 5 pts
b) What is the wavelength of the waves? 5 pts
c) How many waves are generated in two seconds? 10 pts
d) What is the frequency of the waves? 10 pts
e) What is the period of the wave? 10 pts

Answers

Answer 1

Answer:

a) 0.4m

b)2m

c)2

d)1 s^-1

e) 1 s

Step-by-step explanation:

a) The amplitude of the wave is the highest vertical displacement

with respect to this question, this is 0.4m

b) The wavelength of the wave is simply the distance between two crest or troughs

In this question, this is 2m

c) The number of waves generated is 2

d) Frequency of the waves is the number of waves generated per second

if 2 waves are generated in 2 seconds

The number of waves in a second is 2/2 = 1

So the frequency is 1 s^-1

e) Period is 1/frequency

= 1/1 = 1 second

2. The additive inverse is the negative value, -10.

The multiplicative inverse (reciprocal) is 1/10.

Step-by-step explanation:

1. Since the value within the absolute value is not negative then the value remains the same.

2, The opposite of positive 10 could be -10. The reciprocal is 1/10.

Johnathan ran 5 days this week. The most he ran in one day was 3.5 miles. Write an inequality that shows the distance johnathan could of ran any day this week

Answers

An inequality that shows the distance Johnathan could of ran any day this week is:

$x\leq 3.5$

Solution:

Let "x" be the distance Johnathan can run any day of this week

Given that,

Johnathan ran 5 days this week. The most he ran in one day was 3.5 miles

Therefore,

Number of days ran = 5

The most he ran in 1 day = 3.5 miles

Thus, the maximum distance he ran in a week is given as:

$distance = 5 * 3.5 = 17.5$

The maximum distance he ran in a week is 17.5 miles

If we let x be the distance he can run any day of this week then, we get a inequality as:

$x\leq 3.5$

If we let y be the total distance he can travel in a week then, we may express it as,

$y\leq 17.5$

Which is a solution to the equation?(x −2)(x + 5) = 18

x = −10
x = −7
x = −4
x = −2

Answers

If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:

(x - 2) * (x + 5) = 18
x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4

The correct result would be x = - 7.

The solutions to the equation are x = - 7 and x = 4
