Answer:

first term = 4

Step-by-step explanation:

Sₙ = (a₁ * (1 - rⁿ)) / (1 - r)     a₁: first term     r: common ratio     n: terms

15624 = (a₁ * (1 - 5⁶)) / (1 - 5)

          = (a₁ * -15624) / -4

a₁ x (-15624) =15624 x (-4)

a₁ = 4

check: 4+20+100+500+2500+12500 =15624

A mirror is 24 inches high and 28 inches wide. The center of the mirror will hang 514 feet from the floor on a wall that is 8 fe
Vanyuwa [196]

The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches

The dimension of the mirror is given as:

Height = 24\ in

Width = 28\ in

From the center of the mirror to the floor of the wall, the distance is:

Distance =5\frac14\ ft

So, the distance to the top of the mirror will be:

Top = 5\frac 14\ ft + \frac 12 \times Height

Substitute 24 for height

Top = 5\frac 14\ ft+ \frac 12 \times 24\ in

Top = 5\frac 14\ ft+ 12 \ in

Convert feet to inches

Top = 5\frac 14\times 12\ in+ 12 \ in

Top = 63\ in+ 12 \ in

Top = 75 \ in

The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.

So, we have:

Distance = 8\ ft - 75\ in

Convert feet to inches

Distance = 8\times 12\ in - 75\ in

Distance = 96\ in - 75\ in

Distance = 21\ in

Hence, the distance is 21 inches
