2
Step-by-step explanation:
The graphs intersect at 2 points.
The 2 solutions are x = -2 and x = 6.
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
Do the same steps to find 6
Step 1:
Step 2:
On comparing values we get:
Taking:
n-5=0
n=5✓
or
Taking:
n-4=1
n=5✓
