Answer:
last option
Step-by-step explanation:
Let's call the original angle x° and the radius of the circle y. The area of the original sector would be x / 360 * πy². The new angle, which is a 40% increase from x, can be represented as 1.4x so the area of the new sector is 1.4x / 360 * πy². Now, to find the corresponding change, we can calculate 1.4x / 360 * πy² ÷ x / 360 * πy² = (1.4x / 360 * πy²) * (360 * πy² / x). 360 * πy² cancels out so we're left with 1.4x / x which becomes 1.4, signifying that the area of the sector increases by 40%.
Answer:
Step-by-step explanation:
<u>Given function </u>
Inverse of the function is h(x)
<u>To find h(x) replace f(x) with x and x with h(x) in the given function:</u>
- f(x) = x + 3 ⇒
- x = h(x) + 3, and solve for h(x)
- h(x) = x - 3, this is the inverse of f(x)
5.269 as a mixed number is, 5 269/1000
Shown below is the graph on the x-y plane.
Your equation has only one variable, so a graph on the number line is appropriate. It would extend outward from ±2, where the points would be indicated by open circles.
The same reason 4 dimes and 4 pennies aren't equal.
To put it into decimal terms, 4/10 is 0.40 (or forty cents), whereas 4/100 is 0.04 (or four cents)
