Answer:

The gradient of the graph below is $\mathbf{\frac{3}{2} }$

Step-by-step explanation:

We need to calculate the gradient of the graph

The gradient of graph is actually slope of the graph.

The slope of graph can be calculated using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Taking any 2 points on graph i.e

(1,0) and (-1,-3)

We have $x_1=1, y_1=0, x_2=-1,y_2=-3$

Putting values and finding gradient:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-3-0}{-1-1}\\Slope=\frac{-3}{-2}\\Slope=\frac{3}{2}$

So, The gradient of the graph below is $\mathbf{\frac{3}{2} }$

Find the value of the following expression:<br> (28.5-5. 199-2.<br> )<br> 228

USPshnik [31]

<h2>Answer with step-by-step:</h2>

(28.-5.199-2.)228

<em>Subtract 5.199 out of 28 to get 22.801</em>

(28.-5.199-2.) * 228

<em>Subtract 2 of 22.801 to get 20.801</em>

20.80 1 * 228

<em>Multiply 20.801 and 228 to get 4742.628 </em>

4742.628<em> </em>

<h2>The answer if you need to factor it:</h2>

3*11*19*31*61/2*5^3 = 4742 157/250 = 4742.628

Luden [163]

$(x^m)(x^n)=x^{m+n}$
so
$(2^3)(2^5)=2^{3+5}=2^{8}$
