Area of shaded region is 18π square unit.
<u>Step-by-step explanation:</u>
Given :- A circle with center O and radius 9 cm
To Find :- area of shaded region that is area of ABC
Solution : - BC = 9 cm
∠ABC = 80° = Ф
so, area of sector = πr²Ф / 360°
= (π×9×9×80) /360°
= 18π square unit
hence, area of shaded region is 18π square unit
Answer:
A. y = 7(x + 1)²-3
Step-by-step explanation:
Parabola:
Putting into vertex form, remember that:
In this question:
, to put into this format:
We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then
Vertex form:
So the correct answer is:
A. y = 7(x + 1)²-3
8x + 2 > 34
Subtract 2 from both sides to start isolating x
8x > 32
Divide both sides by 8 to isolate x
x > 4
x is greater than 4
Gross income= $813.61
Step-by-step explanation:
Giving the following information:
Sales= $32,874
Fixed salary= $452
Commission= 1.1% paid on sales in excess of $25,000.
To calculate the gross income, we need to use the following formula:
Gross income= 452 + y*x
y= percentage comission
x= sales
For $32,874 sales:
Gross income= 452 + 0.011*32,874
Gross income= $813.61
