if the graph was 7x, the graph enlarges by a factor of 7
Answer:
Step-by-step explanation:
We are given an equation of circle with radius of 5 units:
To find the second derivative, you'd have to <u>differentiate</u> the equation <u>twice</u>.
We can use <u>implicit differentiation</u> to differentiate. Its concept is to derive like a normal for both sides of equation but since we are differentiating with respect to x and we have y-term, we derive normally then multiply by dy/dx or y'.
For simple clarification, you derive normal and <u>apply chain rules</u>. Hence why there's dy/dx multiplied by 2y:
Recall the power rules:
Chain Rules:
Hence:
<em>Note that deriving a constant will always result in 0.</em>
Simplify:
Solve for dy/dx:
We've finally found the first derivative of relation. However, we have to find the second derivative, so we derive dy/dx to find the second derivative:
Therefore:
For this, we will be using quotient rules. Keep in mind that both x and y are function!
Recall quotient rules:
Let u = -x and v = y:
Now we know that dy/dx = -x/y, so we substitute dy/dx as -x/y in the second derivative:
Simplify:
More simplification:
Therefore, the second derivative is:
Answer:
the ans is 105...........
No is not the same
2/1 = 2
1/4 = .25
Write the decimal number as a fraction
(over 1)
19.79 = 19.79 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator = 19.79 × 10 × 10 = 1979
Denominator = 1 × 10 × 10 = 100
Numerator / Denominator = 1979 / 100
Simplifying our fraction
= 1979/100
= 1979/100
= 19 79/100
