Which points are on the graph of g(x) = (1/5)x?

AlexFokin [52]

Given:

The function is

$g(x)=(\dfrac{1}{5})^x$

To find:

The correct ordered pairs.

Solution:

We have,

$g(x)=(\dfrac{1}{5})^x$

For x=3,

$g(3)=(\dfrac{1}{5})^3$

$g(3)=\dfrac{1}{125}$

So, the ordered pair is $(3,\dfrac{1}{125})$ .

For x=-2,

$g(-2)=(\dfrac{1}{5})^{-2}$

$g(-2)=(5)^2$ $[\because (\dfrac{a}{b})^{-n}=(\dfrac{b}{a})^n]$

$g(-2)=25$

So, the ordered pair is $(-2,25)$ .

For x=1,

$g(1)=(\dfrac{1}{5})^1$

$g(1)=\dfrac{1}{5}$

So, the ordered pair is $(1,\dfrac{1}{5})$ .

For x=-1,

$g(-1)=(\dfrac{1}{5})^{-1}$

$g(-1)=(5)^1$ $[\because (\dfrac{a}{b})^{-n}=(\dfrac{b}{a})^n]$

$g(-1)=5$

So, the ordered pair is (-1,5). This is the correct answer.

Therefore, the correct option is D.

The strength of a rectangular beam varies

aleksandrvk [35]

Answer:

1296 pounds per square inch

Step-by-step explanation:

Direct variation equation:

y = kx

In this case it is:

y = kx², where y- strength, x- depth of the beam, k- coefficient

Substitute the given values and solve for k:

3600 = k*10²
3600 = 100k
k = 3600/100
k = 36

The equation becomes:

y = 36x²

Now, find the value of y, when x is 6:

y = 36*6² = 1296

Note, I took the depth as 6 inches but the question is a bit confusing by saying "four six inches". If it is 4 inches then your answer will be:

y = 36*4² = 576

Triangle MNO is a right triangle with one leg = 15ft and the other leg = 18ft. Calculate the

NISA [10]

Answer:

Length of the hypotenuse = 23.43ft

Step-by-step explanation:

First leg = 15ft

Second leg = 18ft

Length of the hypotenuse = ?

In a right angle triangle,

Hypotenuse^2 = opposite^2 + Adjacent^2

Let first leg and second leg of the triangle be opposite and adjacent respectively

Hypotenuse^2 = opposite^2 + Adjacent^2

= 15^2 + 18^2

= 225 + 324

= 549

Hypotenuse^2 = 549

Find the square root of both sides

√Hypotenuse^2 = 549

Hypotenuse = 23.43ft to the nearest of a hundredth

Length of the hypotenuse = 23.43ft

How to finsd the set of numbers if the mean, median and mode is given

Bad White [126]

Answer:

a) we have the numbers 0, 2, 3, 5, 5. The mean and the median are both 3

b) we have the numbers 0, 0, 3, 5, 7. The mean and the median are both 3

In both cases the mean and the median are 3, but the mode differs. The mean and the median do not uniquely determine the mode.
