D = √(x2 - x1)^2 + (y2 - y1)^2) =
= √(6 + 1)^2 + (-2 - 4)^2) =
= √ (7^2 + 6^2) =
= √(49 + 36) =
= √85
Answer:
1) 8
2) 1
Step-by-step explanation:
C - 30%.
We know he spends less than he has expected, so we put it as a fraction calculate the percentage of the error.
So it would be:
87.5/ 125 = 0.7
And 1-0.7 = 0.3
When we move the chemical place two places to the left to make it a percentage, it will become 30%.
The area of the frame is D. 252 in².
<h3>How to calculate the area?</h3>
It should be noted that the frame 2 inches wide surrounds a painting that is 18 inches wide and 14 inches tall.
The area will be:
= Length × Width
= 18 × 14
= 252 in²
The area is 252 inches².

To find an inverse function:
1. Write the function.
2. Replace f(x) with y.
3. Switch x and y.
4. Solve for y.
5. Replace y with

Now let's follow the steps above and do it.
1. f(x) = 4x
2. y = 4x
3. x = 4y
4. y = x/4
5.
