This is an arithmetic sequence, as there is a common difference of 21 between terms.
By using the formula, the 18th term of the sequence is
= 1st term + (18 - 1)(21)
= 15 + 17 * 21
= 372
F=(5,8) e=(4,3) d=(x,y)
(5+x)/2=4 (8+y)/2=3
5+x=8 8+y=6
x=3 y=-2
d=(3,-2)
The answer for this one is 39
Step-by-step explanation:
y=kxz
13=k x 5 x 8
13= 40k
K=13/40
a. y=13/40 x 4 x 10
y=13/40 x 40
y=13
b. 20=13/40 x x x 12
20=13/40 x 12x
20=<u>156x</u>
40
20 x 40=156x
800=156x
X=<u>800</u>
156
X=<u>200</u>
39
X=5 5/39
C. 15=13/40 x 6 x z
15=<u>78z</u>
40
15x40=78z
600=78z
Z=<u>600</u>
78
Z=<u>100</u>
3
Z=7 9/13
Answer:
250 + 0.05 (1500)
