Answer:
2
Step-by-step explanation
8 times y <21. Well, what times 8 gives us less than 21. y is less than or equal to 2.
We have to find on the graph which is f ( - 3 ).
This is the quadratic function which passes through the points: ( - 6, - 3 ), ( 0 , - 3 ) and ( - 3, - 9 ).
Also we can conclude that the point ( - 3, - 9 ) is the minimum value of this function. So : f ( - 3 ) = - 9.
Answer:
A ) - 9.

Answer:
4. 480.38m² 6. 3.35
Step-by-step explanation:
Assuming you're looking for the area of the shaded region, you must first be aware that the entire circle has a 360 angle.
From there. for no. 4:
You subtract 87 from 360 to find the angle of the major arc.
360-87=273
From there you must also know the formula to find the area of a sector which is:
(x/360)×pi×r²
In our case 273 is x and 14.2 is r so
(273/360)×pi×14.2²= 480.38
