Answer:
Hence, the arc length is 2π feet or 6.28 feet.
Step-by-step explanation:
In a circle with a radius of 3 ft, an arc is intercepted by a central angle of 2π/3 radians.
If the central angle is measured in degrees than the arc length is given by:
arc length=(θ\360°)×2πr.
and if central angle is measured in radians than the arc length is given by:
arc length=θr. ( where r is the radius of the circle)
where θ is the central angle.
Hence, here we have:
r= 3 ft.
and θ=2π/3.
Hence the arc length is given by:
Arc length=(2π/3)×3=2π feet.
Hence, the arc length is 2π feet or 2×3.14=6.28 feet.

Answer:
a = √(c² - b²)
General Formulas and Concepts:
Pre-Algebra
- Equality Properties
Step-by-step explanation:
Step 1: Define
a² + b² = c²
Step 2: Rearrange
- Subtract b² on both sides: a² = c² - b²
- Square root both sides: a = √(c² - b²)
And we have our final answer!

2) the slope at the point x=3; will be f´(3);
f´(3)=4(3)=12
answer: the slope will be 12.
Final answer:
The slope of the function y = 2x^2 + 2 at the point x = 3 is 12.
Explanation:
The slope of a function can be determined using the derivative of the function. In this case, the function is y = 2x^2 + 2. Taking the derivative of this function gives us dy/dx = 4x. To find the slope at x = 3, we substitute x = 3 into the derivative: dy/dx = 4(3) = 12.

Given that she makes $9 per hour, it is 9 x h or 9h.
If her tips is a fixed $15 amount, then we simply add 15.
9h + 15
This expression above is the amount she made last Monday.
Since she made no less than $110, meaning she made more than $110 last monday.
The final inequality is: 9h + 15 > 110.
