Answer:351.86 cc( approximately)

Step-by-step explanation:

The volume of the material = External volume - internal volume

= π3^2×50-π 2.6^2×50

=351.86

The volume of the material by the pipe is 351.86 cc.

The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder. The volume of a cylinder is defined as the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it

V = πr²h

where 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

Given that the external and the internal radius of a cylindrical pipe are 3 cm and 2.6cm respectively

The length of the pipe is 50 cm

External volume = π(3)²×50 = 1413.71 cc

internal volume = π (2.6)²×50 = 1061.85

The volume of the material = External volume - Internal volume

The volume of the material = 1413.71 - 1061.85

The volume of the material = 351.86 cc

Step-by-step explanation:

a relation that is not a function

Answer:

Step-by-step explanation:

If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?

f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15

f(1) = 2 - 15 + 22 + 15

f(1)= 24.

No the result is not zero. So x - 1 is not a factor.

However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.

The numbers that do make this zero are -0.5, 3, 5

Which mean that the factors are (2x+1)(x-3)(x - 5)

Answer:

the answer is y=6/5x-7

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-1)-(-7)/5-0

m=6/5

y-y=m(x-x¹)

y-(-1)=6/5(x-5)

y+1=6/5x-6

-1 -1

y=6/5x-7

Answer:

1. T = 5x + 3y

2. 16 tomatoes.

Step-by-step explanation:

1. Determination of the linear expression.

Let x represent the number of pumpkin.

Let y represent the number of tomato.

Let T represent the total sales made from selling the pumpkins and tomatoes.

From the question,

1 pumpkin = $ 5

Hence,

x pumpkin = 5x

1 tomatoe = $ 3

Hence

y tomatoes = 3y

Therefore, the total sales (T) made from selling the pumpkin and tomatoes will be:

T = 5x + 3y

Where:

T is the total sales made from selling the pumpkin and tomatoes.

x is the number of pumpkin.

y is the number of tomatoe

2. Determination of the number of tomatoes sold.

Total cost (T) = $ 98

Number of pumpkin (x) = 10

Number of tomatoe (y) =?

T = 5x + 3y

98 = 5(10) + 3y

98 = 50 + 3y

Collect like terms

98 – 50 = 3y

48 = 3y

Divide both side by 3

y = 48/3

y = 16

Therefore, 16 tomatoes was sold.

Answer:

The remainder is 12.

Step-by-step explanation:

The Polynomial Remainder Theorem

The remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).

We are given the polynomial:

[tex]p (x ) = x^3 - 3x^2 - 10x + 24[/tex]

And we are required to find the remainder when p(x) is divided by (x-1).

We can simply apply the polynomial remainder theorem, substituting x for 1 in the polynomial:

[tex]Remainder=p (1 ) = 1^3 - 3\cdot 1^2 - 10(1) + 24[/tex]

Remainder= 1 - 3 - 10 + 24 = 12

The remainder is 12.

Answer:

none of them are constant of proportinality.

Step-by-step explanation:

because if you divided each one. you do not get the same answer. if you did it would have to be either  of the others, but in this case there is no constant of proportinality in that chart

Answer:

[tex]y = 3.5x[/tex]

Step-by-step explanation:

Required

Determine the equation

First, pick corresponding x and y values

[tex](x_1,y_1) = (6,21)[/tex]

[tex](x_2,y_2) = (14,49)[/tex]

Next, calculate the slope

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives:

[tex]m = \frac{49 - 21}{14 - 6}[/tex]

[tex]m = \frac{28}{8}[/tex]

[tex]m = 3.5[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 21 = 3.5(x - 6)[/tex]

[tex]y - 21 = 3.5x - 21[/tex]

Add 21 to both sides

[tex]y - 21+21 = 3.5x - 21+21[/tex]

[tex]y = 3.5x[/tex]

Relative to the ground, the bullet will not be moving at all, and it will drop straight to the ground.If you fire a gun into the air, the bullet will travel up to a mile high (depending on the angle of the shot and the power of the gun). Once it reaches its apogee, the bullet will fall. ... In crowded cities, however, the probability rises dramatically, and people get killed quite often by stray bullets

Answer:

quarterly N = 4

semi-annually N = 2

Monthly N = 12

annually N = 1

Step-by-step explanation:

The number of compounding times per period for an investment is usually denoted as N in the compound interest formula:

A = P(1 + r/n)^nt

n = number of times in a year for which the amount is compounded :

Annually : compounding times = 1 = 12 /12

Semi annually (6 months) ; N = 12 /6 = 2

Quarterly ; (3 months) ; N = 12 /3 = 4

Monthly ; (12 months) ; N = 12 / 12 = 1

Answer:

[tex]A' = -51[/tex]

Step-by-step explanation:

Given

[tex]A = \left[\begin{array}{ccc}-2&2&-5\\4&-1&-2\\1&3&-5\end{array}\right][/tex]

Required

Determine the determinant of A (A')

If

[tex]A = \left[\begin{array}{ccc}a&b&c\\d&e&f\\g&h&i\end{array}\right][/tex]

Then,

[tex]A' = a(e*i - f * h) - b(d * i - g * f) + c(d * h - e * g)[/tex]

So:

The determinant of [tex]A = \left[\begin{array}{ccc}-2&2&-5\\4&-1&-2\\1&3&-5\end{array}\right][/tex] is

[tex]A' = -2(-1 * -5 -(-2)*3) -2(4 * -5 -(-2) * 1) -5(4 * 3- (-1) * 1)[/tex]

[tex]A' = -2(5 +6) -2(-20 +2) -5(12 + 1)[/tex]

[tex]A' = -2(11) -2(-18) -5(13)[/tex]

[tex]A' = -22 +36 -65[/tex]

[tex]A' = -51[/tex]

Hence, the determinant is -51
