Hello,

The way to find the complement for a 11 degree angle is to subtract 11 from 90, and you get:

79!

A complement angle is basically an angle that equals up to 90 degrees, so if you ever need help with a question like this, remember this answer. Try finding a number that equals up to 90 degrees, so you can do

X + X = 90

Or

90-X= X

Hope this helps, have a good day. c;

How many times longer is the wavelength of a sound wave with a frequency of 20 waves per second than the wavelength of a sound w
sergejj [24]

The sound wave with a <u>frequency of 20</u> waves/sec is 800 longer than the wavelength of a sound wave with a <u>frequency of 16,000</u> waves/sec

<h3>Calculating wavelength </h3>

From the question, we are to determine how many times longer is the first sound wave compared to the second sound water

Using the formula,

v = fλ

∴ λ = v/f

Where v is the velocity

f is the frequency

and λ is the wavelength

For the first wave

f = 20 waves/sec

Then,

λ₁ = v/20

For the second wave

f = 16,000 waves/sec

λ₂ = v/16000

Then,

The factor by which the first sound wave is longer than the second sound wave is

λ₁/ λ₂ = (v/20) ÷( v/16000)

= (v/20) × 16000/v)

= 16000/20

= 800

Hence, the sound wave with a <u>frequency of 20</u> waves/sec is 800 longer than the wavelength of a sound wave with a <u>frequency of 16,000</u> waves/sec

The first step in beginning to control your time is
kotegsom [21]
B. DEVELOPING A TIME LOG is the first step in beginning to control you time.

A. A COMBINATION OF LETTERS AND NUMBERS password is used to ensure security.


Time log is basically you recording or logging the activities you have done in a certain time of a day. As you do this daily and check on the log for a few days, you will notice that you have done things that are either unimportant and time consuming, in short time was wasted.
Time log is very helpful especially is you are very busy. It will not only help you manage your tasks in any given time, it will also show you the things you can do in a shorter amount of time and allow you to schedule time for relaxation.

Passwords should be composed of a combination of letter and numbers. Other use special characters just to tighten password security. It is better that users create passwords that may form a special meaning to them so that they will not forget it regardless of length and combination.

Natasha2012 [34]

Answer:

-503

Step-by-step explanation:

the statement tell us:

(r - 5)^3 + r^2

r= -3

so we have:

(-3 - 5)^3 + (-3)^2

(-8)^3 + 9

-512+9 = -503
