I think the answer is C not to sure
Answer:
Options (2) and (5)
Step-by-step explanation:
Given ratio is a : b and b : c
[Option 2]
b × b = a × c
b² = ac
If a = b,
b² = bc
b = c [Option 5]
Therefore, Options (2) and (5) are the correct options.
Answer: The answer is (c) 3 - 4i.
Step-by-step explanation: We are given a point located on the complex plane and we are to select the correct complex number that is represented by this point.
We can see that the co-ordinates of the point on the plane are (3, -4).
Since the point (a, b) can be written in the form a + bi, where 'a' is the measurement along X-axis and 'b' is the measurement along Y-axis, so the point (3, -4) an be written in the following form:
(3, -4) = 3 + (-4)i = 3-4i.
Thus, (c) is the correct option.
Answer:
here's how you find it ima put a example hello :
the aera of a rectangle is : A = L×W
L : the length W : the width
24.396 = 38× W
W = 24.396/38 cm
W = 0.642 cm
Step-by-step explanation:
Answer: choice A) -8/5
=====================================================
Work Shown:
Use the slope formula which basically says you subtract the y coordinates, then subtract the x coordinates in the same order, then you divide the results (reduce if possible)
m = (y2-y1)/(x2-x1)
m = (-1-7)/(4-(-1))
m = (-1-7)/(4+1)
m = -8/5
