Find the value of x.

valentina_108 [34]

Answer:

x = 100

Step-by-step explanation:

The ratios of long side to hypotenuse are the same for all these triangles.

x/(x+10) = (x+10)/(x+21)

x^2 +21x = x^2 +20x +100 . . . . . multiply by (x+10)(x+21), expand

x = 100 . . . . . . . . . . . . . . . . subtract x^2 +20x

how would you multiply negative numbers? or negative fractions for example -12 x 12 is what and please explain good

galina1969 [7]

Answer:-12 x 12 =- 144.

What you do is multiply regularly then add the negative sign, but if your multiplying 2 negatives it’s a positive answer. I cant help with the Fractions caz I’m not good at them lol .

In a graphing program, graph the following 4 functions in the same coordinate plane.

9966 [12]

See below for the changes when the exponential function is transformed

<h3>How to determine the effect of a</h3>

The exponential functions are given as:

$y = \sqrt x$

$y = 5\sqrt x$

$y = 14\sqrt{x$

$y = -2\sqrt{x$

An exponential function of the above form is represented as:

$y = a\sqrt{x$

See attachment for the graph of the four functions.

<u>When a is large</u>

This is represented by $y = 14\sqrt{x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and it moves closer to the y-axis

<u>When a is small</u>

This is represented by $y = 5\sqrt x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and it moves away from the x-axis

<u>When a is negative</u>

This is represented by $y = -2\sqrt{x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and is reflected across the y-axis.
