Answer:
≈ 18.3 m²
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of sector - area of right triangle
area of sector = area of circle × fraction of circle
A = πr² ×
= π × 8² × = 64π × = 16π m²
area of triangle = × 8 × 8 = 4 × 8 = 32 m²
shaded area is then
A = 16π - 32 ≈ 18.3 m² ( to the nearest tenth )
Domain:
-4 ≤ x ≤ 3
or in different form:
x ∈ [-4; 3]
So as there are 9 reds, you know that the total number of counters is 100 (because red probability is 9/100)
so you can work out x by writing an equation.
9 + 3x + x - 5 + 2x = 100
from here you can add up all of the x's and the numbers (so you have 3x+x +2x = 6x)(and for numbers you have 9 and -5, 9 - 5 = 4) so putting these together you have 6x and 4 you get the following:
6x + 4 = 100
take away 4 from both sides
6x = 96
divide both sides by 6
x =96/6 = 16
green is x-5 so if you substitute the result we got for x...
16-5 = 11. so there are 11 greens
therefore the probability would be 11/100 as there are 100 counters overall.
Answer:
see below
Step-by-step explanation:
The odd degree (7) tells you the end behaviors are in opposite directions. The negative leading coefficient (-4) tells you the sign of y will be opposite the sign of x.
For x going toward negative infinity, y goes toward positive infinity.
For x going toward positive infinity, y goes toward negative infinity.
