proportional means y increases with x in a linear way not parabolic for example i don't know though why graph two will be wrong may be because it doesn't start at zero but i guess graph one is the right answer

Find the first four iterates of the function f(x) = (x - 5)2 with an initial value of x0 = 4.
mina [271]

Answer:

  b.  1; 16; 121; 13,456

Step-by-step explanation:

A suitable calculator or spreadsheet can compute these for you.

Put the value of x into the formula to find the first iterate. Repeat for successive iterates.

_____

<em>Comment on the answer choices</em>

You can eliminate the first two answer choices because none of the numbers 19, 645, 12645 are perfect squares. You can eliminate the last answer choice because the first term listed is x0, not x1.

One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cyl
mojhsa [17]

The correct equation is:

216 = \frac{7}{8} \times x - 8

The volume of second cylinder is 256 centimeter cubed

<em><u>Solution:</u></em>

Given that,

One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder

The first cylinder’s volume is 216 centimeter cubed

From given,

Let "x" be the volume of second cylinder

Therefore,

Volume of first cylinder = 7/8 of the volume of a second cylinder - 8

216 = \frac{7}{8} \times x - 8

216 = \frac{7x}{8}-8\\\\216 = \frac{7x-64}{8}\\\\7x - 64 = 8 \times 216\\\\7x - 64 = 1728\\\\7x = 1728 + 64\\\\7x = 1792\\\\Divide\ both\ sides\ by\ 7\\\\x = 256

Thus the volume of second cylinder is 256 centimeter cubed
