What is the graph of the linear function that is represented by the equation y= 1/2x-2

kondor19780726 [428]

Answer:

See picture attached.

Step-by-step explanation:

Start with the y-intercept of -2 and plot that on the graph. Then, use the slope of 1/2x to plot more points to help you draw the line. Remember rise over run. Go up one from the y-intercept and right two. If you need to, you can also go down one and left two.

Hope this makes sense.

ABC IS a right angled triangle at B and D is a point on BC. If AD=18cm , BD=9cm and CD = 4 cm, find AC

leva [86]

$AB = \sqrt{ AD^{2} - BD^{2} } = \sqrt{243} = 9 \sqrt{3} 
$
$AC = \sqrt{ AB^{2} + BC^{2} } = \sqrt{412} = 2 \sqrt{103}$

For 33 hrs of work you are paid 252.45 how much would you receive for 36 hours

poizon [28]

For 33 Hours, It is = $252.45

Now, for 1 Hour, It is 252.45 / 33 = 7.65

Now, For 36 hours, It would be: 7.65 * 36 = 275.4

In short, Your Answer would be: $275.4

Hope this helps!

HELP, I’M STUCK !

vaieri [72.5K]

Since P(X = x) = 0.3 for all 0 ≤ x ≤ α, we have

$\displaystyle\int_{-\infty}^\infty P(X=x)\,\mathrm dx=1\implies0.3\int_0^\alpha\mathrm dx=0.3\alpha=1\implies\alpha=\dfrac{10}3$

So,

$P(X>2) = \displaystyle\int_2^\infty P(X=x)\,\mathrm dx=0.3\int_2^{\frac{10}3}\mathrm dx$

$P(X>2)=0.3\left(\dfrac{10}3-2\right)=\boxed{\dfrac25}$
