8 0

Two Perpendicular lines intersect at a single point called the"Intersection".

If The Two Lines Are Y=Ax+B And Y=cx+d, Then Their Intersection Has X Coordinate(d-b)/(a-c) And Y Coordinate {A(d-b)/(a-c)+b}

Which expression represents the value of the series below? 3+ 7 + 11 + 15 + ... + 1,671

torisob [31]

Answer:

Step-by-step explanation:

This is an Arithmetic Series with common difference 4 and first term 3

so the nth term an = 3 + (n -1)4

= 4n - 1.

The sum of n terms

= n/2 (a1 + L)

= n/2(3 + 1671)

= 837n.

There are (1671-3) / 4 + 1 = 418 terms in the series,

so the total value of the series is 837*418

= 349,866.

6/9 written two different ways

Rashid [163]

6/9 is equivalent to the fractions 60/90 and 600/900. The amount of zeros you add on does not matter as long as you do it to the top and bottom. The division sign cancels it out.

EXPRESS in power notation

lora16 [44]

Answer:

Solution given:

-1/8= $\frac{-1³}{2³}=(\frac{-1³}{2³}=-1³*2^{-3}=-2^{-3}$

2. -64/27

= $\frac{-4^{3}}{3³}=\frac{-4³}{3³}=(\frac{-4}{3})^{3}$

Express in rational number

1. (-3/2)=-3/2*2/2=-(3*2)*(2/2)=-6/4

2. (1/5)=1/5*5/5=5/25

and

(-4/3)³(2/5)-⁴ ÷ (7/4)

(-4³/3³)(2-⁴/5-⁴)÷7/4

(-64/27)(5⁴/2⁴)÷7/4

(-64/27)(625/16)÷7/4

(-64*625/(27*16))*4/7

-2500/27*4/7

-10000/169

(-100/13)²
