There are 7 similarly shaped figures in a set. The largest figure is 7 inches tall. Each of the other figures is 1 inch shorter
galben [10]
The first thing we must do for this case is to find the scale factor based on the dimensions of the figures.
 The largest figure is 7 inches tall. Each of the other figures is 1 inch shorter than the next larger figure.
 We have then that the smallest figure has a height of 1 inch.
 The scale factor is:
 k = (smallest figure) / (largest figure) = 1/7
 k = 1/7
 The surface area of the smaller figure is:
 A = k ^ 2 * (A ')
 Where
 A ': surface area of the largest figure.
 Substituting:
 A = (1/7) ^ 2 * (588)
 A = 12 in ^ 2
 Answer:
 
The surface area of the smallest figure is:
 
A = 12 in ^ 2

the space station has an average orbit of 250 miles above the earth. how many pennies would it take to make a stack that high? p
hram777 [196]

Answer:

264694796.312

Step-by-step explanation:

A penny is 0.0598 inches (1.52 mm) in thickness. (0.75 is the diamiter).

Hear me out. Now we gotta convert it to miles to divide 250 by the number  (there's 6.21371e-7 miles in one mm). first convert the mm to inches (by dividing the length value by 63360). We get 9.444842171717e-7 or 9.44484e-7 for a shorter form. Last step 250/9.444842171717e = 264694796.312.

Oh btw I'm not very sure on this answer correct me please if I'm wrong.

x^4+12x^3+37x^2+12x+36=0\\\\x^4+12x^3+36x^2+x^2+12x+36=0\\\\&#10;x^2(x^2+12x+36)+(x^2+12x+36)=0\\\\x^2(x+6)^2+(x+6)^2=0\\\\(x^2+1)(x+6)^2=0\\\\\\x^2+1=0\qquad\vee\qquad x+6=0\qquad\vee\qquad x+6=0\\\\x^2=-1\qquad\vee\qquad x=-6\qquad\vee\qquad x=-6\\\\\boxed{x=i\qquad\vee\qquad x=-i\qquad\vee\qquad x=6\qquad\vee\qquad x=6}

The function has two imaginary and two real zeros.
