Answer:

the formula is V=BH

Step-by-step explanation:

if the prism is rectangular prism : it has three dimensions then V=length * height * width

V= L*H*W or V= base*H

or V=BH

in your question it does not show V=BH maybe it is misprint

The volume of the prism is V = Bh , where B is the base area and h is the height of the prism

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

Identify the shape of the base of the prism: The base of the prism can be any polygon, such as a triangle, rectangle, or hexagon. It is important to identify the shape of the base because the formula for calculating the area of the base will depend on the shape.

Calculate the area of the base: Once the shape of the base has been identified, calculate the area of the base using the appropriate formula. For example, if the base is a rectangle, the area would be calculated as length x width.

Multiply the area of the base by the height of the prism: Once the area of the base has been calculated, multiply it by the height of the prism to get the volume. The height is the perpendicular distance between the two parallel bases of the prism.

Hence , by following these three steps, you can calculate the volume of a prism regardless of its shape, as long as you can identify the shape of the base and calculate its area.

Answer:

The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.

Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.

In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.

nth term of the geometric sequence

an= -12*3^(n-1)

Step-by-step explanation:

First term

a= -12

Second term

ar= -36

-12r=-36

r=-36/-12

=3

Third term

ar^2= -108

-12(3)^2

= -12(9)

= -108

nth term of the geometric sequence

an=ar^(n-1)

Answer:

C) 3.9 sec

Step-by-step explanation:

You have given the time formula; t = square root of d divided by square root of 4.9.

Well d = 75m

square root of 75 = 8.66

square root of 4.9 = 2.2

8.66 / 2.2 = 3.9363...

t = 3.9 sec

Answer:

Step-by-step explanation:

The given Equation y=-1/3x+7 represents the table on the left side because when x = 0 y = 7. The equation for the table on the left is y=1/3x+5 because when x = 0 y = 5 and when y goes up 1 x goes up 3. The solution is (3, 6) because the only point in both tables is (3, 6)

Answer:

y = (1/3)x + 5

Step-by-step explanation:

y = (-1/3)x + 7 matches the second table (the table on the right side).  Note that if x = 0, y = 7, and that this point, (0, 7) is found in the second table.  The other table shows that when x = 0, y = 5; this point, (0, 5), is the y-intercept of the function whose values are in the first table.  To finish this work, we need onlyl find the slope of the function represented by the first table:

y = mx + b becomes 6 = m(3) + 5, or  1 = 3m, or m = 1/3.

The the function represented by the first table is y = (1/3)x + 5.

Answer:

2'nd atom

Step-by-step explanation:

There are two atoms one weighs

6.022*10^-29 grams

another weighs

1.66*10^-17 grams

Which atom has a greater mass?

Work:

-29-(-17)=-12

-29 is 12 decimal places smaller than ^-17

0.000000000006.022*10^-17=1.66*10^-17

0.000000000006.022=1.66

0.000000000006.022<1.66

atom 1 < atom 2

We can conclude that the second atom is the greater.

Answer:

The sequence is an arithmetic sequence.

Common difference = 0.6

Step-by-step explanation:

Given

-2.8, -2.2, -1.6, -1.0

Required

State if it's an arithmetic progression

Also state its common difference

To know if a sequence is arithmetic or not, we simply check for common difference

Common difference is calculated by subtracting a lower term with its immediate higher time;

In other words

[tex]Common difference = T_2 - T_1 = T_3 - T_2 = T_4 - T_3 = ......[/tex]

Where T represent Term and the number represent their positions;

So, from the given above

[tex]T_1 = -2.8\\T_2 = -2.2\\T_3 = -1.6\\T_4 = -1.0[/tex]

Calculating [tex]T_2 - T_1[/tex]

[tex]T2 - T1 = -2.2 - (-2.8)\\T2 - T1 = -2.2 + 2.8\\T2 - T1 = 0.6\\[/tex]

Calculating [tex]T_3 - T_2[/tex]

[tex]T_3 - T_2 = -1.6 - (-2.2)\\T_3 - T_2 = -1.6 + 2.2\\T_3 - T_2 = 0.6[/tex]

Calculating [tex]T_4 - T_3[/tex]

[tex]T_4 - T_3 = -1.0 - (-1.6)\\T_4 - T_3 = -1.0 + 1.6\\T_4 - T_3 = 0.6[/tex]

Notice that all the above workings gave the same result;

This shows that the sequence is an arithmetic sequence.

The result of each workings above is the common difference

Common difference = 0.6

Answer:

The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2

Step-by-step explanation:

The functions given to us is:

f(x) = 3(x - 1)² + 2

As there is no limitation of x, all value of x are possible. So

Domain = All real numbers

For all values of x, the minimum value of y is 2 calculated at x = 1. The rest of the values are greater than 2. So,

Range = y ≥ 2

Simplifying the function:

f(x) = 3(x² + 1² - 2(x)(1)) + 2

f(x) = 3(x² - 2x + 1) +2

f(x) = 3x² - 6x + 3 + 2

f(x) = 3x² - 6x + 5    (ax² + bx + c)

where a = 3, b = -6, c = 5

x-coordinate of Vertex is given as:

Vertex(x) = -b/2a = 6/2(3)

Vertex(x) = 1

Substitute x=1 in the function, we get

Vertex(y) = 2

So Vertex is at (1,2)

Answer: A. The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2.

Answer:

Step-by-step explanation:

1. If m<2 = 32°

the measure for m<4 is 148°

x + 32° = 180°

x = 148°

measure of m<6 = 148° alternate interior of m<4

2. If m<1 = 65°, then m<2 and m<3  are also 65°

Both m<2 and m<3 are vertical angles therefore they are 65°

m<1 and m<2 are corresponding angles therefore they are 65°

Answer:

7 hr 10 min 12 seconds

Step-by-step explanation:

Maria, an experienced shipping clerk, can fill a certain order in 13 hours. Felipe, a new clerk, needs 16 hours to do the same job. Working together, how long will it take them to fill the order?

------------------------

Maria rate = 1/13 job/hr

-----

Felipe rate = 1/16 job/hr

----

Together rate = 1/x job/hr

-------

Equation:

rate + rate = Together rate

1/13 + 1/16 = 1/x

----

16x + 13x = 13*16

------

29x = 13*16

Answer:

364

Step-by-step explanation:

14!/(3!(14-3)

Answer:

364

Step-by-step explanation:

You need to choose 1 out 14 for the first position, then 1 out of the 13 left  for the second position, then 1 out the 12 left for the third position.

That gives 14 * 13 * 12 = 2184.

If order mattered, that would be the answer, but in this case, since order does not matter, the 3 positions can be filled in 3 * 2 * 1 ways = 6 ways.

2184/6 = 364

Answer:

( f h ) (x)  = 6 x² - 1

Step-by-step explanation:

Step(i):-

Given f(x)   =  3 x - 4

         g (x)  = −x²+2 x−5

        h (x)  = 2 x² + 1

         j (x)    = 6 x + 2 - 8 x

        K (x)   = 3 x² - x + 7

Step(ii):-

( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )

                            =  3 (2 x² + 1 ) - 4

                            =  3 ((2 x² ) + 3 - 4

                           =   6 x² - 1

Final answer:-

∴ ( f h ) (x)  = 6 x² - 1

Answer:

The constant 8 represents the height of the stack and hence the number of coasters.  (It represents the number of coasters.)

Step-by-step explanation:

The formula for finding the volume of a cylinder is

V = πr²h

If you we take π =3.14 and h = 1 cm, as given in the question, then we can rewrite the formula for the volume of one coaster as

V = 3.14 * r²

But the formula in this question is

V(r) = 8*3.14 * r² so this means that there are 8 coasters here hence the formula for one coaster being multiplied by 8.
