A c and d are the answers
Step-by-step explanation:
gradient = slope or several other words.
it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.
it is represented by the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
in our case, when going from A to B we have
x changes by -2k (from 3k to k).
y changes by -11 (from 8 to -3).
so, the gradient or slope is
-11/-2k = 3
11/2k = 3
11 = 3×2k = 6k
k = 11/6
A = (33/6, 8) = (11/2, 8)
B = (11/6, -3)

<u>Answer:</u>
The geometric mean between each pair of numbers 
<u>Solution:</u>
The Geometric mean between two numbers a and b is given as Geometric mean =
--- eqn 1
The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root for the numbers.
From question, given that two numbers are 
Hence we can say “a” =
=7
Similarly “b” =
= 29
We have to find the geometric mean between “7” and “29”
By using equation 1,
Geometric mean between 7 and 29 =
= 14.24
Hence the geometric mean between
