You cant solve this because there is no matching variables like for example:
x^2-3xy+2x-2y-4+xy-5x+6y+8 and i solved this which the answer is x^2-3x+4y-2xy+2 because there are matching variables.
Plugging in the values, we get 7(6)-4=42-4=38.
Answer:
$35.20
Step-by-step explanation:
S.I. = (P×R×T)/100
=(160×5.5×4) /100
= (640×55) / 100×10
= (64×55) / 100
= 3520 / 100
= $ 35.20

Answer:
<h3>1</h3>
Step-by-step explanation:
The nth term of an exponential sequence is expressed as ar^n-1
The nth term of a linear sequence is expressed as Tn = a + (n-1)d
a is the first term
r is the common ratio
d is the common difference
n is the number of terms
Let the three consecutive terms of an exponential sequence be a/r, a and ar
second term of a linear sequence = a +d
third term of a linear sequence = a + 2d
sixth term of a linear sequence = a + 5d
Now if the three consecutive terms of an exponential sequence are the second third and sixth terms of a linear sequence, this is expressed as;
a/r = a + d ..... 1
a = a + 2d ..... 2
ar = a+ 5d .... 3
From 2: a = a + 2d
a-a= 2d
0 = 2d
d = 0/2
d = 0
Substitute d = 0 into equation 1:
From 1: a/r = a + d
a/r = a+0
a/r = a
Cross multiply
a = ar
a/a = r
1 = r
Rearrange
r = 1
<em>Hence the common ratio of the exponential sequence is 1</em>
1. B A C
Reason:
A: 4
is 12.6
B: the Square root of 18.7 is 4.32
2. a
Reason: the square root of 80 is 8.9, thus closest to 9 from all the others.
3. C
Reason: 6/7 = 0.86, and the square root of 3/4 = 0.87
