Find k so that the following function is continuous on any interval: . . f(x)=kx if 0<=x<3 and f(x)=8x^2 if 3<=x. . K=?

Tasya [4]

In finding the value of this inequality first is to substitute the X to the F(x) so that it would be rearrange to get the value of k. So if 3<=x, K is directly proportional to X so it means that K >=3

Which statement is true about the line represented on the equation y + 7 = -3 (x - 2/9) ?

Zarrin [17]

ANSWER

The point $(\frac{2}{9},-7)$ lies on the straight line $y+7=-3(x-\frac{2}{9})$

EXPLANATION

The given line is $y+7=-3(x-\frac{2}{9})$ . It can be observed that the given straight line is in the point-slope form.

We can rewrite the equation in the point-slope form to obtain,

$y--7=-3(x-\frac{2}{9})$ .

When we compare this to the general point-slope form, which given by the formula;

$y-y_1=m(x-x_1)$ ,

We can observe that,

$x_1=\frac{2}{9}$ and $y_1=-7$ .

Hence the point, $(x_1,y_1)=(\frac{2}{9},-7)$ lies on $y+7=-3(x-\frac{2}{9})$

Determine the two positive integers each square root falls between.

sertanlavr [38]

Answer:

10. (5, 6)

11. (1, 2)

12. (7, 8)

13. (10, 11)

14. (27, 28)

15. (11, 12)

Step-by-step explanation:

If you're not familiar with the squares of small integers, your calculator can help you figure this.

10. √28 ≈ 5.291 . . . . between 5 and 6

11. √3 ≈ 1.732 . . . . between 1 and 2

12. √59 ≈ 7.681 . . . . between 7 and 8

13. √115 ≈ 10.724 . . . between 10 and 11

14. √772 ≈ 27.785 . . . . between 27 and 28

15. √140 ≈ 11.832 . . . . between 11 and 12

The distance between two points is the number of units between them.

Halfway points (a) and (b)

To locate a point halfway points (a) and (b), we use the following steps

Calculate the absolute difference between both points
Divide the absolute difference by 2
Add the quotient to the smaller point.

Assume the smaller value is (a), the point (P) halfway points (a) and (b) would be

$P = a + \frac{|a - b|}{2}$

Take for instance, a = 5, and b = 10.

The halfway point would be:

$P = 5 + \frac{|5 - 10|}{2}$

$P = 5 + \frac{5}{2}$

$P = 5 + 2.5$

$P = 7.5$

The halfway point between 5 and 10 is 7.5

The formula works for negative values, and absolute values are used to return the actual difference between both points

Real world circumstance

The formula can be used to calculate the halfway distance between a school gate and the school library (as an instance)

Fractional distance

To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.

Take for instance, three-fourths from (a) to (b) would be:

$P = a + \frac{3|a - b|}{4}$
