Answer:

a. 1

b. 5

Step-by-step explanation:

Ordered pairs are (x, f(x)). You want f(2), so you look for an ordered pair that lists 2 as the first number. That one is (2, 1). This means f(2) = 1.

f(2) is plotted as the point (2, f(2)). That is, the x-coordinate of the point will be 2. The point that has x-coordinate 2 is (2, 5).

As above, this means f(2) = 5.

The distance between the parallel lines x – 2y = 3 and 2x – 4y = 12 is

Svetradugi [14.3K]

Given :

Parallel lines are

x – 2y = 3 and 2x – 4y = 12

Step-by-step explanation:

Lets write the given lines in slope intercept form y=mx+b

$x -2y = 3 \\-2y=-x+3\\Divide \; both \; sides \; by -2\\y=\frac{x}{2} -\frac{3}{2}$

From the above equation , y intercept of first line is $\frac{-3}{2}$

Solve the second equation for y and find out y intercept

$2x-4y=12\\-4y=-2x+12\\Divide \; by \; -4\\y=\frac{1}{2} x-3$

y intercept of second line is -3

To find the distance between parallel lines, we subtract the y intercepts

$\frac{-3}{2} -(-3)=\frac{-3}{2} +\frac{6}{2} =\frac{3}{2} =1.5$

Answer:

The distance between the parallel lines = 1.5

Whats an outlier?

ANTONII [103]

Answer:

In statistics, an outlier is a data point that differs significantly from other observations.

Step-by-step explanation:

An outlier may be due to variability in the measurement or it may indicate experimental error; the latter are sometimes excluded from the data set. An outlier can cause serious problems in statistical analyses.

QUESTION 5 The lengths of the legs of a right triangle are 9 cm and 40 cm. What is the length of the hypotenuse? 41 cm 65 cm 49

GREYUIT [131]

Using Pythagoras' Theorem

$c {}^{2} = 9^{2} + {40}^{2}$
$c = \sqrt{81 + 1600 }$
$c = 41$

So, the answer is 41 cm.
C refers to the hypotenuse
