10 and 11

√116 = 10.77 → ( to 2 decimal places )

hence 10 < √116 < 11

Find three rational numbers between 1 and 0.

Alex73 [517]

Answer:

1/2, 1/4 & 3/4

Step-by-step explanation:

mean of 0 &1 is $\frac{0+1}{2} =\frac{1}{2} \\$

mean of 0 and 1/2 is $(0+\frac{1}{2} )/2=\frac{1}{2} /2=\frac{1}{2} *\frac{1}{2} =\frac{1}{4}$

mean of 1/2 and 1 is $(\frac{1}{2} +1)/2=\frac{3}{2} /2=\frac{3}{2} *\frac{1}{2} =\frac{3}{4}$

So the three rational numbers are 1/2, 1/4 & 3/4

CD is perpendicular to AB and passes through point C5, 12).

Aleksandr-060686 [28]

Answer:

x intercept of CD = 17

Step-by-step explanation:

We are given a line AB with its end coordinates. and Another line segment CD which is perpendicular to AB. We have the coordinates of C , and we are asked to find the x intercept of line CD.

For that we need to find the equation of CD

we have coordinates of C , and hence if we have slope of CD we can find equation of CD

Slope of CD can be determine with the help of slope of AB as CD⊥ AB

So, the slope of CD $mCD = -\frac{1}{mAB}$

Hence we start from determining slope of AB

slope is given as

$m= \frac{y_2-y_1}{x_2-x_1}$

$m= \frac{14-(-3)}{7-(-10)}=\frac{17}{17}=1$

Hence $mAB=1$

There fore $mCD=-1$

(∵ Product of Slopes of two perpendicular lines is always -1)

Now we find the equation of CD with the help of slope -1 and coordinates of C(5,12)

$m=\frac{y-y_1}{x-x_1}$

$-1=\frac{y-12}{x-5}$

$-x+5=y-12$

$y=-x+17$

Hence we have our equation , now in order to find the x intercept we keep y = 0 in it and solve for x

$0=-x+17$

$x=17$

Hence the x intercept is 17

8. What are the advantages of switching a quadratic function from standard form into vertex form?

Airida [17]

Answer:

vertex form automatically gives you your vertex and your y intercept so all you need to do is graph. Hope this helps
