Answer:
The last graph (to the far right).
Step-by-step explanation:
As long as each x-value has one y-value, it is a function. However, the last graph has an x-value at -1 where there are two y-values. So, it does not pass the Vertical Line Test, and it is a relation rather than a function.
Hope this helps!
It’s 3! 3x4 is 12 and 5 isn’t a factor of 12
Mark the fee as x. Then, make the following equation :
The initial fee is $ 50, and the hourly rate is 1.2 times higher. Thus, the hourly rate is
Her hourly rate is $60.
We know that
Area of a regular polygon = (1/2)*apothem<span>*perimeter
</span>perimeter <span>of the regular decagon=10*a
where
a is the length side of the decagon
in this problem
a=1.8 ft
so
</span>perimeter of the regular decagon=10*1.8----> 18 ft
Area of a regular decagon = (1/2)*2.8*18----> 25.2 ft²
<span>Round to the nearest whole number------> 25 ft</span>²
the answer is
25 ft²
1 : do 10 - 7 = 3
2: -2.5 • 3 = -7.5
3: -7.5 + -5 = -12.5
The answer is B
