Inflection at f'(x) = 0 
<span>
x^1/2 / (1 + x + x^3) = 0 </span>

<span>The x coordinate is x = 0 </span>
<span>
or "C" from your choices there. </span>

<span>The simplest way is to notice that this happens when x = 0. The reason is you got: </span>
<span>
x^1/2 / (some expression) </span>
<span>
at x = 0 the numerator is 0 so unless the denominator is also 0 the result is 0. </span>
<span>
The denominator for x = 0 is 1 so you get </span>
<span>
0/1 = 0.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

If x, y, and z are integers greater than 1, and (327)(510)(z) = (58)(914)(xy), then what is the value of x?
algol [13]

Answer:

<u>Statements (1) and (2) TOGETHER are NOT sufficient.</u>

Explanation:

As in the equation (327)(510)(z) = (58)(914)(xy) there are THREE variables in total i.e. "x", "y" and "z" hence minimum three equations are required to find out values of all variables. Hence,

If the given number of equations is equal to total variable used in any of the equation, values of all the variables can be find out otherwise there can be unlimited number of solutions.

So, value of "x" cannot be determined with the given data.

In one minute, Evan can do nine less than four times the number of push-ups that Lucy can do. if they did 61 push-ups in all, ho
vagabundo [1.1K]

Evan does 33 more push-ups than Lucy

let x be the number of push-ups Lucy does , then

Evan does 4x - 9 push-ups

The total number of push-ups is 61

hence x + 4x - 9 = 61 has to be solved

that is 5x - 9 = 61

add 9 to both sides

5x = 61 + 9 = 70

divide both sides by 5

x = \frac{70}{5} = 14

Lucy does 14 push-ups and Evan does 4x - 9 =(4 × 14) - 9 = 47

Thus Evan does 47 - 14 = 33 more push-ups than Lucy

Explanation on How to answer what is the density of an object that has a mass of 73,430 and the volume of 7 m3
scZoUnD [109]

Answer:

Density = 10,490 g/m³

Step-by-step explanation:

Density = mass ÷ volume

here mass = 73,430 g

        volume = 7 m³

density = 73,430 ÷ 7

             = 10490 g/m³

Density = 10,490 g/m³
