1: 2i^20 + i^42
2: i^101 - i^2
Answer:
1. i^20 X (2+i^22)
2. i² X (i¹¹-1) X (i²² + i¹¹ + 1) X (i^66 + i³³ + 1)
Step-by-step explanation:
1) 2i^20 + i^42
factor out i^20
i^20 X (2 + i^22)
2) i^101 - i²
i²X(i^99-1)
i²X(i³³-1)X(i^66+i³³+1)
Using a³-b³=(a-b)(a²+ab+b²)
i²X(i¹¹-1)X(i²²+i¹¹+1)X(i^66+i³³+1)
i²X(i¹¹-1)X(i²²+i¹¹+1)X(i^66+i³³+1)

Step-by-step explanation:
what is the volume???
Answer:
80 cm^3
Step-by-step explanation:
In order to find the volume of an object, you must multiply the length x width x height of the object. In the case of this pyramid, you also must multiply by 1/3 in the end. This looks like 5x6x8x(1/3) = 80 cm^3
Answer:
I got 240 but I'm not sure if that is correct
Step-by-step explanation:
volume is the space inside and you find out with length x width x height and that's what I did. I guess the number just seems high
A coat that was $125 but it marked down 30%
Answer: $87.50
Step-by-step explanation:
Did a short way I learned.
Since we are marking down did

Did 125(0.7) and got 87.50.
I am 100% sure this is right.
Which of the following is equal to 10.6 ÷ 2?
A.
(10 ÷ 2) + (0.6 ÷ 2)
B.
(10 ÷ 2) + (2 ÷ 0.6)
C.
(10 ÷ 2) - (6 ÷ 2)
D.
(10 ÷ 2) - (0.6 ÷ 2)
Answer:
[tex]\huge\boxed{\sf Option\ A }[/tex]
Step-by-step explanation:
10.6 ÷ 2 = 5.3
Now,
Part A)
(10 ÷ 2) + (0.6 ÷ 2)
= 5 + 0.3
= 5.3
No need to solve other parts. The correct option is A.

Luke's car depreciates in value by 12% per year.
Luke bought his car for £18000
Work out how much his car will be worth after 4 years.
Answer:
£9360
Step-by-step explanation:
£18000× 12 ÷100 = £2160
£2160 × 4 = £8640
£18000 - £8640 = £9360
Therefore his car will be worth £9360 after 4 years

:)
Step-by-step explanation:
Given
5x + 2y = 16 .....i)
x + 2y = 4 .....ii)
Subtracting equation I) and ii) we get
5x + 2y = 16
x + 2y = 4
- - -
4x = 12
x = 3
Putting x = 3 in equation ii)
3 + 2y = 4
2y = 4 - 3
y = 1/2
x =3 and y = 1/2
Hope it helps :)

In triangle RST the vertices have coordinates of R(-1,10),S(5,4)and T (-4,-2). If the midpoints of side RS and RT were connected with a segment, what would the slope of this segment be?
Plz helppp
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Midpoint of a line segment joining points [tex](x,y)[/tex] and [tex](u,v)[/tex] is given by [tex](\frac{x+u}{2},\frac{y+v}{2} )[/tex]
Points are R(-1,10),S(5,4)and T (-4,-2).
Midpoint of RS = [tex](\frac{-1+5}{2},\frac{10+4}{2} )=(\frac{4}{2},\frac{14}{2} )=(2,7 )[/tex]
Midpoint of RT = [tex](\frac{-1-4}{2},\frac{10-2}{2} )=(\frac{-5}{2},\frac{8}{2} )=(\frac{-5}{2},4)[/tex]
Slope of a line joining points [tex](a,b)[/tex] and [tex](c,d)[/tex] is given by [tex]\frac{d-b}{c-a}[/tex]
Slope of line joining midpoints of side RS and RT = [tex](\frac{4-7}{\frac{-5}{2}-2 })=(\frac{-3}{\frac{-9}{2} })=\frac{2}{3}[/tex]
