It’s been awhile since I’ve done a problem like this but I believe it’s solved as below:
The area of a circle is equal to πr2. That will tell you the entire area of the circle. Then you would need to divide that by 2 to get the area of the 180° arc.
So, the area of this circle is 153.94 square meters. If you divide that by 2 (since 180° is half of a circle) you would get 76.97 square meters.
Answer:
Step-by-step explanation:
Given that: x
2
+6x+8
=x
2
+4x+2x+8, (split middle term)
=(x
2
+4x)+(2x+8), (group pair of terms)
=x(x+4)+2(x+4), (factor each binomials)
=(x+4)(x+2), (factor out common factor (x+4)
Hence factors of x
2
+6x+8 are (x+4)(x+2)
The set of x values of a function is another name for domain. and the set of y values of a function is another name for range.
hope this helps, God bless!
Answer:
Not possible
Step-by-step explanation:
The notation (f °g)(-2) means f(g(-2)). You will substitute -2 into g(x) then substitute the value or equation that results into f(x).
g(-2) = √x - 16 = √-2 - 16
This is not possible because the value of -2 cannot be found in a square root. Square roots do not compute real roots for negative numbers.
10*0.25=2.5
2.5/10*100=25 lbs
25-10=15 lbs
