Answers

Answer 1

Caroline spent
$34.78 on chicken breast, and the price per pound is 2.52.5. To calculate the number of pounds she bought, we can divide the total cost by the price per pound.

34.78/2.52.5 = 13.8476 pounds

To the nearest hundredth of a pound, Caroline bought 13.85 pounds of chicken breast.

fuel pressure in the fuel tank of the space shuttle is decreasing at a rate of r(t)= 17e^-0.1t psi per second at time t in seconds. at what rate is pressure decreasing at 15 seconds

Answers

The pressure is decreasing at a rate of approximately 0.26 psi/s at t = 15 seconds.

What is pressure ?

In physics, pressure is the amount of force applied per unit area. It is a scalar quantity, which means that it has a magnitude but no direction. Pressure is typically denoted by the symbol P, and its units are commonly expressed in pascals (Pa), which is the SI unit of pressure.

Pressure can be defined as the amount of force F applied per unit area A:

P = F / A

For example, if a force of 100 newtons (N) is applied to an area of 2 square meters (m^2), then the pressure would be:

P = 100 N / 2 m^2 = 50 Pa

Pressure is an important concept in many areas of physics, including fluid dynamics, thermodynamics, and atmospheric science. It is commonly used to describe the behavior of gases and liquids under different conditions, such as changes in temperature or volume. Pressure can also be used to calculate other physical properties, such as the flow rate of a fluid or the speed of sound in a gas.

According to given condition :

The rate of change of the fuel pressure in the fuel tank of the space shuttle is given by the derivative of the function [tex]r(t) = 17e^(-0.1t)[/tex]psi per second with respect to time t. Taking the derivative of r(t), we get:

[tex]r'(t) = (-0.1) * 17e^(-0.1t)[/tex]Simplifying this expression, we get:

[tex]r'(t) = -1.7e^(-0.1t)[/tex]

To find the rate at which the pressure is decreasing at t = 15 seconds, we substitute t = 15 into the expression for r'(t):

[tex]r'(15) = -1.7e^(-0.1*15)[/tex]

r'(15) ≈ -0.26 psi/s

Therefore, the pressure is decreasing at a rate of approximately 0.26 psi/s at t = 15 seconds.

y = -6x + 5
-2x + y = 5

Answers

Answer: 0,5

x = 0
y = 5

Answer: (0,5)

Step-by-step explanation:

Since "y" is equal to -6x+5 everywhere you see a "y" you can replace it with -6x+5.

-2x-6x+5=5

Combine like terms

-8x+5=5

Isolate x (subtract 5 from both sides)

-8x=0

Solve for x

x=0

Now that you have the value for "x" you can substitute the value into either equation and solve for y

-2(0)+y =5

y=5

the product of permutation matrices is again a permutation matrix. True/False

Answers

The statement which is given as , "The product of permutation matrices is again a permutation matrix." is True.

A permutation matrix is a square matrix whose entries are either 0 or 1 and has exactly one "1" in each row and each column. In other words, it is a matrix that represents a permutation of the rows (or columns) of the identity matrix.

When two permutation matrices are multiplied, the result is another square matrix with exactly one "1" in each row and each column. To see why this is true, consider two permutation matrices, A and B. Suppose that A is a m x m matrix and B is a m x m matrix. The product of these two matrices is another m x m matrix, C = AB.

Each entry in the matrix C is given by the dot product of the corresponding row in A and the corresponding column in B. If the row in A has a "1" in the i-th position and the column in B has a "1" in the j-th position, then the i,j-th entry in C will be "1".

Since both A and B are permutation matrices, each row in A and each column in B has exactly one "1". This means that each row in C will have exactly one "1", and each column in C will also have exactly one "1". Hence, C is also a permutation matrix.

a^2 ÷ a^2 = a^(2-2) = a^0 = 1

b^5 ÷ b^4 = b^(5-4) = b^1 = b

So, 36a^2b^5 ÷ 9a^2b^4 = 4b

The required equation which intersects the points (12, -2) and (6, -8) in the point-slope form is y+2 = x-12.

What is point-slope form?

The general form of a linear equation is y-y1=m(x-x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).

To understand more about it and see some instances, watch this video.

Both the slope-intercept form and the point-slope form can be used to write the equation of a straight line.

The slope and ANY point on the line are highlighted using the point-slope form.

Slope intercept form merely shows the slope and the y-intercept of a line.

So, we have:

m = 1

And points are (12, -2) and (6, -8)

We need to use the points: (12, -2)

Now, form the equation as follows:

y - (-2) = m (x-12)

y + 2 = 1(x-12)

y+2 = x-12


Therefore, the required equation which intersects the points (12, -2) and (6, -8) in the point-slope form is y+2 = x-12.

The triangle represents 1/4 of the whole trapezoid, the rhombus represents 1/2 of the whole trapezoid, and the hexagon represents 1/1 of the whole trapezoid.

Determine the fraction

Each of the shapes represent a different fraction of the whole trapezoid.

The triangle represents 1/4 of the whole trapezoid. This is because there are four triangles in the trapezoid, and each one is equal in size. Therefore, each triangle is 1/4 of the whole trapezoid. The rhombus represents 1/2 of the whole trapezoid. This is because there are two rhombuses in the trapezoid, and each one is equal in size. Therefore, each rhombus is 1/2 of the whole trapezoid.

The hexagon represents 1/1 of the whole trapezoid. This is because there is only one hexagon in the trapezoid, and it is equal in size to the whole trapezoid. Therefore, the hexagon is 1/1, or the whole trapezoid.

In conclusion, the triangle represents 1/4 of the whole trapezoid, the rhombus represents 1/2 of the whole trapezoid, and the hexagon represents 1/1 of the whole Hexagon. These fractions can be used to determine the value of each shape in relation to the whole trapezoid.

A 6x + 2

Answers

We can use the Pythagorean theorem, which states that for a right triangle with legs of lengths a and b, and hypotenuse of length c, the following relationship holds:

a² + b² = c²

In this case, the lengths of the legs of the right triangle are 2x + 3 and 4x - 1. We can use these values to set up the equation:

(2x + 3)² + (4x - 1)² = c²

Simplifying the left-hand side:

4x² + 12x + 9 + 16x² - 8x + 1 = c²

20x² + 4x + 10 = c²

Therefore, the polynomial equivalent to c² is C) 20x² + 4x + 10.

The smallest pair of 4-digit numbers such that the difference between them is 303 and their HCF is 101 are 1010 and 1313.

HCF (Highest Common Factor) of two numbers, which is the largest number that divides both numbers evenly.

Let's call the smaller of the two numbers "x". The larger number would be "x + 303".

The HCF of these two numbers must be 101, which means that 101 must be a factor of both x and x + 303.

To find the smallest possible value of x, we need to find the smallest number that is divisible by 101 and also a 4-digit number.

The smallest multiple of 101 that is a 4-digit number is

=> 101 x 10 = 1010.

Therefore, x = 1010.

The larger number would be

What is Polynomial?

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.

Given:

The polynomial zeros are given as:

x = 7, x = -1 and x = -3

x - 7 = 0, x + 1 = 0 and x + 3 = 0

So, f(x) = (x - 7)(x + 1)(x + 3)

f(x) = (x - 7)(x² + 4x +3)

f(x) = x³ -3x² -25 x -21

Now, Rational function g(x)

g(x) = f(x) / (x² - x + 2)

After Factorizing

g(x) = (x-2) - 25x+ 25 /  (x² - x + 2)

The slant asymptote is the quotient i.e. x - 2

Hence, the slant asymptote of the function g(x) is x - 2

So, the discontinuities of g(x)

g(x) = (x³ -3x² -25 x -21) /  (x² - x + 2)

Set the denominator to 0

x² - x + 2 = 0

(x - 2)(x + 1) = 0

x= 2 or x= -1.

So, the discontinuities and their types are:

Given, the distance traveled by an object in t = 30 minutes is 2 miles

Let "v" be the final velocity of an object,

"u" be the initial velocity of an object,

and "a" be the acceleration of an object.

From the standard velocity equation:

final velocity = initial velocity + acceleration * time.....(1)

(final velocity)² = (initial velocity)² + 2*acceleration * distance....(1)

From equation (1)

v = u + a*30 minutes
