Vertices of the triangle are
Coordinates (a,b) when reflected about x-axis is given as (a,-b) i.e. Y coordinate changes its sign
Answer:
The name of the structure is ethyl acetate with one double bond. The attached document contains the structure of the compound
Step-by-step explanation:
¹H NMR =δ4.07(quartet), 1.97( singlet), 1.18(triplet)
2H 3H 3H
¹³C NMR = δ 170, 60, 20, 10 ppm
from the molecular formula,C₄H₈O₂ and spectrum study, the structure of the compound will have a double bond which is calculated as DU= 4+1-(8/2)= 1
thus, the name of the compound as drawn in the attachment is ethyl acetate
Answer:
A. 2.2
Step-by-step explanation:
You can actually find the answer pretty quickly by just dividing the numerator and the demonitator do 20/9 = 2.22222222
The recursive formula of the sequence is f(n) = 12 + f(n -1), where f(1) = 5
<h3>How to determine the recursive formula?</h3>
The explicit formula of the arithmetic sequence is given as;
f(n) = 5 + 12(n - 1)
Open the bracket
f(n) = 5 + 12n - 12
Evaluate the like terms
f(n)= 12n - 7
Calculate f(1) and f(2)
f(1)= 12(1) - 7= 5
f(2)= 12(2) - 7= 17
The difference between f(1) and f(2) is 12
Hence, the recursive formula of the sequence is f(n) = 12 + f(n -1), where f(1) = 5
