The formula for finding the Volume of square pyramid is given by :

$V = a^{2} \frac{h}{3}$

where a is base edge and,

h = height.

We are given in the figure,

base edge = 18cm

Height =12 cm

So plugging these values in the formula for volume , we have

$V = (18)^{2} \frac{12}{3}$

On solving we get ,

Volume of square pyramid = 1296 cm³.

So first option is the correct choice .

The graph of f(x) = StartRoot x EndRoot is reflected across the x-axis and then across the y-axis to create the graph of functio

allsm [11]

Answer:

The true statements:

The only value that is in the domains of both functions is 0.

The range of g(x) is all values less than or equal to 0.

==================================

Step-by-step explanation:

See the attached figure:

As shown: f(x) = √x with blue color

When f(x) is reflected across the x-axis the result will be (-√x) with red color.

Then the is reflected result across the y-axis to create the graph of function g(x) = -√(-x) with green color.

Domain of f(x) = [0,∞) & Range of f(x) = [0,∞)

Domain of g(x) = (-∞,0] & Range of g(x) = (-∞,0]

So, according to previous, we will check the statements:

1) The functions have the same range. (Wrong)

2) The functions have the same domains. (Wrong)

3) The only value that is in the domains of both functions is 0. (True)

4) There are no values that are in the ranges of both functions. (Wrong)

5) The domain of g(x) is all values greater than or equal to 0. (Wrong)

6) The range of g(x) is all values less than or equal to 0. (True)

Provide an example of a trig function that includes multiple transformations. Describe how it is different from the standard tri

klio [65]

An example of a trig function that includes multiple transformations and how it is different from the standard trig function is; As detailed below

<h3>How to interpret trigonometric functions in transformations?</h3>

An example of a trigonometric function that includes multiple transformations is; f(x) = 3tan(x - 4) + 3

This is different from the standard function, f(x) = tan x because it has a vertical stretch of 3 units and a horizontal translation to the right by 4 units, and a vertical translation upwards by 3.

Another way to look at it is by;

Let us use the function f(x) = sin x.

Thus, the new function would be written as;

g(x) = sin (x - π/2), and this gives us;

g(x) = sin x cos π/2 - (cos x sin π/2) = -cos x

This will make a graph by shifting the graph of sin x π/2 units to the right side.

Now, shifting the graph of sin xπ/2 units to the left gives;

h(x) = sin (x + π/2/2)

Find three consecutive integers such that the product of the first and third is 5 greater than 5 times the second.

ivolga24 [154]

Answer:

Step-by-step explanation:

3 consecutive integers....

1st integer = x

2nd integer = x + 1

3rd integer = x + 2

the product of 1st and 3rd is 5 greater then 5 times the 2nd...

x(x+2) = 5(x + 1) + 5

x^2 + 2x = 5x + 5 + 5

x^2 + 2x = 5x + 10

x^2 + 2x - 5x - 10 = 0

x^2 - 3x - 10 = 0

(x - 5)(x + 2) = 0

x - 5 = 0 x + 2 = 0

x = 5 x = -2

so it will be : 5,6,and 7 or -2,-1, and 0
