Carlos's answer is not correct. He did not do the perentesis first. He subtracted 2 from 20 getting 18 and then multiplied it by 6, which gave him 108. He then added 8, getting 116 and then divided that by 4. This gave him the incorrect answer of 29. The correct answer would be 4. Hope this helps!! :)

Carlos did not use order of operations. The order of operations goes first you do <span>Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. First you do the parentheses which is 2 x 6 so now your equation is 20 - 12 + 8 / 4. Since you don't have any exponents nor multiplication left you move onto divison which is 8 / 4. Know your equation is 20 - 12 + 2. You do addtion which is 12 + 2. Then you do subtraction 20 - 14 which equals 6.

Hope this helps :)</span>

Wheel I has diameter 23.4. Wheel ll has diameter 18.0. Round the diameter of each wheel to the nearest inch. About how much fart

11111nata11111 [884]

Answer:

Wheel1 = 147inches , wheel 2 = 113inches

Wheel 1 will travel 147 revolutions.

Step-by-step explanation:

Finding the circumference of both wheels

Wheel 1 = 2 pi r = 2 × 3.142 × 23.4 = 147.05 inches. To the nearest inches = 147inches

Wheel 2 = 2 pi × r = 2 × 3.142 × 18 = 113.11inches . To the nearest inches = 113inches.

I rotation = 1 revolution

In 1 rotation, wheel 1 will travel= 147 × 1 = 147 revolutions.

What is the end behavior? 10 points!!

Colt1911 [192]

Given:

The given function is:

$f_1(x)=-3\cdot 2^{x-5}-4$

The graph of the function is given.

To find:

The end behavior of the given function.

Solution:

We have,

$f_1(x)=-3\cdot 2^{x-5}-4$

From the given graph it is clear that the function approaches to -4 at x approaches negative infinite and the function approaches to negative infinite at x approaches infinite.

$f_1(x)\to -4$ as $x\to -\infty$
