Answer:

Use the formula Tn=a+(n-1)d

a= the first term in the sequence which is - 1

d=the difference between the terms which is 4

Tn= -1+(n-1)(4)

Tn=-1+4n-4

Tn=4n-5

How much fabric is needed to create the lateral faces of the tent?

jek_recluse [69]

Left and right side: 6.4*7=44.8
44.8+44.8=89.6
front (where the zipper is) and back: half of 5*8=20
20+20=40

40+89.6=129.6

the area of the bottom is 7*8=56

the total area is 129.6+56=185.6

I am not sure what lateral area includes. To me, the answer should be 129.6, but 129.6 is not a choice.
I'd suggest 185.6, the total surface area.

Which of the following expressions is equal to 1 divided by 16

Ber [7]

The correct answer is: [A]: " ( $\frac{1}{2}$ )⁴ " .
_______________________________________________

Note: ( $\frac{1}{2}$ )⁴ = $\frac{1^{4} }{2^{4} }$ ;

= $\frac{1*1*1*1}{2*2*2*2}$ ;

= $\frac{1}{16}$ .
_______________________________________________________

Consider "Choice [B]" : "( $\frac{1}{2}$ )⁴ " ;

Note: ( $\frac{1}{4}$ )⁴ = $\frac{1^{4} }{4^{4} }$ ;

= $\frac{1*1*1*1}{4*4*4*4}$ ;

= $\frac{1}{256}$ .

Note that: " $\frac{1}{256}$ " $\neq$ " $\frac{1}{16}$ " .
__________________________________________________________

Consider "Choice [C]" : "( $\frac{1}{8}$ )² " ;

Note: ( $\frac{1}{8}$ )² = $\frac{1^{2} }{8^{2} }$ ;

= $\frac{1*1}{8*8}$ ;

= $\frac{1}{64}$ .

Note that: " $\frac{1}{64}$ " $\neq$ " $\frac{1}{16}$ " .
__________________________________________________________
→ As such, the only correct answer choice is:
__________________________________________________________
Answer choice: [A]: " ( $\frac{1}{2}$ )⁴ " .
