Answer:
Step-by-step explanation:
(x - 3)/2 = -1/2
x - 3 = -1
x = 2
(y + 1/2)/2= 3
y + 0.5 = 6
y = 5.5
(2, 5.5) the other endpoint
Y= aˣ . This is the exponential function:
If x = 2, then y = 36
36 = a² → a = 6
Then the equation becomes: y = 6ˣ
To simplify 4/(2+7i), we multiply it by a fraction equal to one that removes the i value in the denominator. The best value to do this is the complex conjugate divided by itself, so we have 4(2-7i)/((2+7i)(2-7i)). Simplifying, we have (8-28i)/(4-(-49))=(8-28i)/53, which is a completely simplified fraction since 8 and 53 are relatively prime (or coprime), and there are no radicals in the denominator.
30 x 0.75 = 22.5 .............(1st)
22.5 x 0.75 = 16.875 ......(2nd)
16.875 x 0.75 = 12.66 ....(3rd)
ANSWER: C) 12.66
