The inequality can be used to find the domain of
Answer: Option B
<u>Step-by-step explanation:</u>
We have , domain is the set of all possible x-values which will make the function "work", and will output real y-values. Basically to find domain of any function means to find range of values of x that will give real values of y.
For the equation , we know that there's no value ( iota or complex numbers are there but here we will deal with real numbers ) of negative numbers under square root
∴ must be greater than or equal to 0.

answer a)
soln,
or, 4x + 84 = 180° [being co-interrior angle]
or, 4x = 180 - 84
or, 4x = 96
or, x = 96/4
x = 24
answer b)
soln,
or, 2x + 5 = 135° [being corresponding angle]
or, 2x = 135 - 5
or,2x = 130
or, x = 130/2
x = 65°

<u>Answer:</u>
D) R0 , 360°
<u>Explanation:</u>
<u>We are given that the rotation is:</u>
(x,y) --------> (x,y)
This means that the point is rotated back into its original position.
This means that full rotation occurred.
Since the full rotation is 360°, therefore, the correct answer is D
<u>For the other options:</u>
<u>Rotation 90° gives:</u>
(x,y) ----------> (-y,x)
<u>Rotation 180° gives:</u>
(x,y) ----------> (-x,-y)
<u>Rotation 270° gives:</u>
(x,y) ---------> (y,-x)
Hope this helps :)
Answer:
458,700 = 4.587 * 10^5
Step-by-step explanation:
Let's see what a scientific notation is.
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
The given number is 458,700
= 4.587 * 10^5
You can see 4.587 is less than 10.
The number of decimal point moved is represented by 10^5.
Hope this will helpful.
Thank you.
Answer:
35
Step-by-step explanation:
Here we see 5 black keys for every 7 white keys.
So the ratio is 5:7
If we need 49 white keys, find the amount we scale the original ratio by:
49/7 = 7
So we are scaling by a factor of 7.
The number of black keys would be 5 * the scale of 7. = 35
So there should be 35 black keys.
