Answer:

Step-by-step explanation:
The exponential function that decrease by 15% every time x increases by 1 is given by:

We simplify the parenthesis to get:

Therefore the decrease by 15% every time x increases by 1 is

The second choice is correct.
7k/3 = 21
x 3 x3
7k = 63
/7 /7
k = 9
(7(9)/3 = 21 = 63/3 = 21 = 21 = 21)
Lets calculate gear ration T2/T1
so the gear ratio will be 1.6 it simply means dat if u rotate large gears one full revolution it tends to turn another short wheel to 1.6 revs, so in ur qtion the large whell revs 100 den u must multiply wid 1.6*100= 160 revs

Answer:
Given expressions are equivalent.
Step-by-step explanation:
Given expression:
4 (x + 3) + 2x and 6 (x + 2)
Find:
Given equivalent expressions or not
Computation:
By taking LHS
4 (x + 3) + 2x
4x + 12 + 2x
6x + 12
By taking RHS
6 (x + 2)
6x + 12
We say that
LHS = RHS
So,
Given expressions are equivalent.
