Answer:
102.86
Step-by-step explanation:
cos 55 = 59/x
x = 59/cos 55
x = 102.86
-1/2
-2(4x - 3) = 10
First distribute the -2 to 4x and -3; it turns into
-8x + 6 = 10
The subtract 6 on both sides which equals
-8x = 4
Then divide -8 on both sides...
x = -4/8 or -1/2
a) 96/16÷6
b) 31.25/ (2.5)^2=5
c) = V/ pi r^2
b
so the value of the function at x=-3 is -192
