What is the range of the function f(x) = + 6? f(x) > –8 f(x) > –6 f(x) > 6 f(x) > 8

1 answer:

3 0

We know that
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain

case a) f(x) = + 6
the range is 6

case b) f(x) > –8
the range is the interval (-8,∞)

case c) f(x) > –6
the range is the interval (-6,∞)

case d) f(x) > 6
the range is the interval (6,∞)

case e) f(x) > 8
the range is the interval (8,∞)

Given : ΔPQR, QM is altitude of the triangle

PM = 8

MR = 18

To find = QM

Solution :

PR = 8 + 18 = 26

Let, PQ = x , QR = y, QM = z

Applying Pythagoras Theorem in ΔPQR

$PQ^2+QR^2=PR^2$

$x^2+y^2=(26)^2$ ..[1]

Applying Pythagoras Theorem in ΔPQM

$PM^2+QM^2=PQ^2$

$8^2+z^2=(x)^2$ ..[2]

Applying Pythagoras Theorem in ΔQMR

$MR^2+QM^2=QR^2$

$18^2+z^2=(y)^2$ ..[3]

Putting values of $x^2$ and $y^2$ from [2] and [3 in [1].

$8^2+z^2+18^2+z^2=(26)^2$

$2z^2=(26)^2-(8)^2-(18)^2$

$2z^2=288$

$z^2=144$

z = ±12

z = 12 = QM ( ignoring negative value)

The length of QM is 12.

A group of student has 20 Male and 10 females what is the ratio of female-to-male

Nitella [24]

Answer:

The ratio of female-to-male is 1:2

Step-by-step explanation:

There are 10 female students and 20 male students. If we were to divide each number by 10, we would get 1 and 2, respectively. That means for every 1 female student, there are 2 male students. The ratio would then be 1:2.
