Answer:
(7-4i)+(-2+5i) = 5 + i
Answer = 5 + i
Step-by-step explanation:
Group the real part and the imaginary part of the complex number
( 7 - 4i ) + (-2 + 5i )
= ( 7 - 2 ) + ( -4 + 5 ) i
Refine = 5 + i
Answer:
{2, 8}
Step-by-step explanation:
We want to find x for ...
15 = 4|x -5| +3
12 = 4|x -5| . . . . subtract 3
3 = |x -5| . . . . . . divide by 4
±3 = x -5 . . . . . . show the meaning of absolute value
5 ±3 = x = {2, 8} . . . . . add 5
The values of x for which f(x) = 15 are 2 and 8.
For this case we have an equation of the form:
y = A (b) ^ x
Where,
A: initial height
b: growth rate
x: time
Substituting values we have:
y = 6 (2) ^ x
Answer:
An equation that best represent how tall the sunflower will b in x weeks is:
y = 6 (2) ^ x
D!! It’s super easy I hope you can learn how to do it
