What is the volume of this square pyramid?

Mathematics
2 answers:
LuckyWell [14K]3 years ago

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 .

Given the functions: f(x) = x^2-9 and g(x) = 3 what is (f/g)(x)? A. x-3 B. x-9 C. x+3 D. x+9
uysha [10]

Answer:

f + g)(x) = f (x) + g(x)

= [3x + 2] + [4 – 5x]

= 3x + 2 + 4 – 5x

= 3x – 5x + 2 + 4

= –2x + 6

(f – g)(x) = f (x) – g(x)

= [3x + 2] – [4 – 5x]

= 3x + 2 – 4 + 5x

= 3x + 5x + 2 – 4

= 8x – 2

(f × g)(x) = [f (x)][g(x)]

= (3x + 2)(4 – 5x)

= 12x + 8 – 15x2 – 10x

= –15x2 + 2x + 8

\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(

g

f

)(x)=

g(x)

f(x)

= \small{\dfrac{3x+2}{4-5x}}=

4−5x

3x+2

My answer is the neat listing of each of my results, clearly labelled as to which is which.

( f + g ) (x) = –2x + 6

( f – g ) (x) = 8x – 2

( f × g ) (x) = –15x2 + 2x + 8

\mathbf{\color{purple}{ \left(\small{\dfrac{\mathit{f}}{\mathit{g}}}\right)(\mathit{x}) = \small{\dfrac{3\mathit{x} + 2}{4 - 5\mathit{x}}} }}

How many teaspoons of brine shrimp every day? There are about 125,000 Brine shrimp in 1 pound. A pound contains 96 teaspoons. A
sveticcg [70]

Answer:

2\frac{38}{125}\ teaspoons

Step-by-step explanation:

we know that

There are about 125,000 Brine shrimp in 1 pound

1 pound contains 96 teaspoons

so

There are about 125,000 Brine shrimp in 96 teaspoons

Using proportion

Find out how many teaspoons of brine shrimp represent 3000 Brine shrimp

Let

x -----> the number of teaspoons

\frac{96}{125,000}=\frac{x}{3,000}\\\\x=3,000(96)/125,000\\\\x=\frac{288,000}{125,000}\ teaspoons

Simplify

\frac{288}{125}\ teaspoons

Convert to mixed number

\frac{288}{125}\ teaspoons=\frac{250}{125}+\frac{38}{125}=2\frac{38}{125}\ teaspoons

What is the slope of a line that contains the points (-4,-8) and (2,-2)
Bond [772]

Answer:

1

Step-by-step explanation:

Slope is given by

m = (y2 -y1)/(x2-x1)

   = ( -2 - -8)/( 2 - -4)

   =( -2+8) / (2+4)

   =6/6

   =1
