Answer:
<h2><u><em>
A) -1</em></u></h2><h2><u><em>
B) -1.5 or -3/2</em></u></h2>
Step-by-step explanation:
Solve 3-4 and (1⁄2)-2
3 - 4, 4 is greater than 3, so the result is negative (-1)
3 - 4 = -1
-----------------
1/2 is equal to 0.5, also here 2 is larger and we will have a negative result (-1.5 or -3/2)
1/2 - 2 =
0.5 - 2 = -1.5 or -3/2
To get the radius we proceed as follows:
area=θ/360πr²
area=40 sq. units
θ=110°
thus the value of r will be:
40=110/360πr²
r²=40(110/360*π)
r²=41.66966
r=6.4552
2 / (z-5) = z / (0.5z^2 + 7)
cross multiply
z(z - 5) = 2(0.5z^2 + 7) =
z^2 - 5z = z^2 + 14 =
z^2 - z^2 - 5z = 14
-5z = 14
z = -14/5
