Answer:
5.86cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the circle
Area of rectangle = Length * Width
Area of rectangle = 3cm * 3cm
Area of rectangle = 9cm²
Area of the circle = πr²
Given radius r = 1cm
Area of the circle = 3.14(1)²
Area of the circle = 3.14cm²
Area of the shaded region = 9 - 3.14
Area of the shaded region = 5.86cm²
Answer:
The function rule can be written as: f(x) = 2x-3
So, when we input 3, we replace all of the x's for 3's and have: f(3) = 2(3)-3.
This simplifies to be: f(3) = 3, meaning that 3 is the output.
Hope this helps!
Answer:


Step-by-step explanation:
Verify each case
case 1) 
Multiply in cross and then compare both sides

----> is true
therefore
Is a valid proportion
case 2) 
Multiply in cross and then compare both sides

----> is not true
therefore
Is not a valid proportion
case 3) 
Multiply in cross and then compare both sides

----> is not true
therefore
Is not a valid proportion
case 4) 
Multiply in cross and then compare both sides

----> is true
therefore
Is a valid proportion
case 5) 
Multiply in cross and then compare both sides

----> is not true
therefore
Is not a valid proportion
