Answer:

See below

Step-by-step explanation:

\sqrt[3]{49}  = 3.65930571002 \approx3.66 \\  \\ so \:  \sqrt[3]{49} should \: lie \: at \: 3.6 \: which \:  \\ fall \: between \: 3 \: and \: 4.

Actually Lin did a mistake, she obtained square root and not cube root.

Answer with Explanation:

  • 3\sqrt{49} should be placed<u> in-between 3 and 4</u> on the number line (a little bit approaching number 4). The cube root of 49 is 6.66. Therefore, <em>it shouldn't be placed on number 7.</em>

  • Lin thought that she was asked to get the<em> square root of 49</em>, which looks like this: \sqrt{49}. Probably, she missed the number 3. It was actually asking for the<em> cube root of 49</em>. This is also the reason why she placed the dot on the number 7 because the<em> square root of 49 is 7</em>.

What is the distance between point R (−1, 7) and point T (−7, 7) ?
zepelin [54]
You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:
R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.

|-1 - (-7)| = |-1 + 7| = |6| = 6

The distance is 6 units

Divide (-3х + 4 + 18х^2 )by (5 + 6x)
Leokris [45]

Answer:

The division will be represented as:

\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}

Step-by-step explanation:

1) Let's find a number with a variable that multiplied by 6x gives as 18x². It will be 3x, because (6x+5)3x=18x²+15x.

Now, let's subtstract:

(18x^{2}-3x+4)-(18x^{2}+15x)=-18x+4

2) Let's find a number with a variable that multiplied by 6x gives as -18x. It will be -3, because (6x+5)(-3)=-18x-15.

Now, let's subtstract:

(-18x+4)-(-18x-15)=19  

Therefore, the division will be represented as:

\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}

I hope it helps you!
