Answer:
Domain, range
Step-by-step explanation:
The <u>domain</u> of a function is the complete set of inputs, whereas the <u>range</u> is the set of all outputs.
Domain= Input
Range= Output
28.27 is the area bc i had this as an example before lol
5.100 x 10⁻³ = 5.100 x 0.001
= 0.005100 (shift the decimal point for 5 by 3 units left)
Alternatively, because 10⁻³ = 1/1000, therefore
5.100 x 10⁻³ = 5.1/1000
0.0051
---------------
1000 | 5.100
5000
-------------
1000
1000
This yields the same result.
Answer: b. 0.005100
Answer:
3
Step-by-step explanation:
Again, anything to the 0th power is equal to 1.
The 0th power is attached to the b, so this means that b = 1. Multiply 9 and (1) together to get 9.
Now you can subtract 9 from 12 to get 3 as your final answer.
Answers:
- The direct variation equation is y = 5x
- If x = 4, then y = 20
=================================================
Explanation:
Let's say that the letter k replaces the green box
We have the equation y = kx
Plug in (x,y) = (7,35) to get the equation 35 = k*7
Dividing both sides by 7 leads to k = 5
Therefore, the direct variation equation is y = 5x
We can check this by plugging in x = 7
y = 5x
y = 5*7
y = 35
So x = 7 leads to y = 35 as expected.
-------------
Do the same for x = 4
y = 5x
y = 5*4
y = 20 when x = 4
Side note: direct variation equations always go through the origin.
