Number 15 is no solution.
Number 27 is that x has to be between -2 or 2.
This could be explained as -2≤x≤2
Answer:
21 and 10.5 respectively
Step-by-step explanation:
Remember circumference of a circle is given as;
C= 2×π×r; r is raduis
r = C / 2×π
=65.98/(2×3.142)= 10.50
D= 2× r = 2× 10.50= 21.0( D represent diameter)
Note π = 3.142 a known constant
The ordered pair (7,3) means there is an “x” value of 7, and a “y” value of 3 at said coordinate.
Answer:
5/12 hours
Step-by-step explanation:
Honon = 3 1/4 hours
Sequoia = 2 5/6 hours
How much more time did Honon spend on homework than Sequoia
= number of hours Honon spent - number of hours Sequoia spent
= 3 1/4 hours - 2 5/6 hours
= 13/4 - 17/6
= (39-34) /12
= 5/12 hours
Answer:
The first four terms are 3,9,27,81
Step-by-step explanation:
<u>Step :-1</u>
Given first term of sequence is 
Given 'n' t h term is 
.............(1)
here we put n = 2 in equation (1)
..............2
put in equation (2)
put n=3 in equation (1)
put n= 4 in equation (1)
The first four terms of the sequence is
3 , 9, 27 , 81 ....this is geometric sequence
a =3 and ratio term is r =3
