If y is inversely proportional to the square root of x and y=−70 when x=49, find y if x=2401.
Dahasolnce [82]

The value of y when x= 2401 is -10

<h3>How to determine the value of x?</h3>

An inverse variation is represented as:

y = \frac{k}{\sqrt x}

Where k is the proportionality constant

When y = -70, x = 49

So, we have:

-70 = \frac{k}{\sqrt {49}}

Take the square root of 49

-70 = \frac{k}{7}

Multiply through by 7

k = -490

Substitute k = -490 in y = \frac{k}{\sqrt x}

y = -\frac{490}{\sqrt x}

When x =2401, we have

y = -\frac{490}{\sqrt {2401}}

Evaluate the square root

y = -\frac{490}{49}

Divide

y = -10

Hence, the value of y when x= 2401 is -10

Find X please.......
nikdorinn [45]
So Angle 5 = 1x - 7 and angle 2 = -2x + 18. You can work out that angle 1 is the same as angle 5 because corresponding angles are equal. Then you know that angle 1 + angle 2 = 180 because angles on a straight line add to 180. So therefore 1x - 7 -2x + 18 = 180 so -1x + 11 = 180 so -x = 169 so x = -169. Hope this helps :)

A plant cell is 0.00001267 meter wide.How is this number written in scientific notation?
MA_775_DIABLO [31]
<span>The answer is 0.00001267 m = 1.267 * 10^(-5) m. In scientific notation, the number is written as two factors - a number m from 0-10 and 10 raised to the n power: m x 10^n. 0.00001267 m = 1.267 x 0.00001 m. 0.00001 m = (0.1)^5 = 10^(-5). So: 0.00001267 m = 1.267 x 0.00001 m = 1.267 x (0.1)^5 m = 1.267 x 10^(-5) m.</span>
