Catori traveled for 7/2 hours at 15 mph and 4 hours at 4 mph.

Catori started biking to the mall at 15 mph and it took her x hours to travel y miles.

After x hours, her bike got a flat, so she had to walk the rest of the way. She walked at 4 mph, and it took her z hours to travel the remaining 72 miles to the mall.

Since the total trip to the mall took 7 hours, we can calculate that x + z = 7.

We can also calculate that y + 72 = 72.

Using these two equations, we can solve for x and z.

x + z = 7
y + 72 = 72

Subtract 72 from both sides of the second equation to get:

y = 0

Substitute 0 for y in the first equation to get:

x + z = 7

Solve for z:

z = 7 - x

Substitute 7 - x for z in the second equation to get:

y + (7 - x) = 72

Simplify the equation to get:

y = 72 - 7 + x

Substitute 72 - 7 + x for y in the first equation to get:

x + (7 - x) = 7

Simplify the equation to get:

2x = 7

Divide both sides of the equation by 2 to get:

x = 7/2

Substitute 7/2 for x in the equation y = 72 - 7 + x to get:

y = 72 - 7 + (7/2)

Simplify the equation to get:

y = 72 - (7/2)

Therefore, Catori traveled for 7/2 hours at 15 mph and 4 hours at 4 mph.

The product of (t + 5) and (t² + 3t + 10) is t³ + 8t² + 25t + 50.

What is polynomial?

A polynomial is a mathematical expression that consists of variables and coefficients, which are combined using arithmetic operations such as addition, subtraction, multiplication, and non-negative integer exponents.

We can use the distributive property to multiply these two polynomials:

(t + 5)(t² + 3t + 10) = t(t² + 3t + 10) + 5(t² + 3t + 10)

Now we need to simplify each of these terms:

t(t² + 3t + 10) = t³ + 3t² + 10t

5(t² + 3t + 10) = 5t² + 15t + 50

Putting them together, we have:

(t + 5)(t² + 3t + 10) = t³ + 3t² + 10t + 5t² + 15t + 50

Now we can combine like terms:

t³ + 8t² + 25t + 50

Therefore, the product of (t + 5) and (t² + 3t + 10) is t³ + 8t² + 25t + 50.

To estimate the number of blocks per pound, we need to divide the weight in pounds by the average weight of each block.

Given the options of 10, 20, 30, and 40 blocks, let's calculate the number of blocks per pound for each option:

10 blocks per pound: Each block would weigh approximately 1/10th of a pound.

20 blocks per pound: Each block would weigh approximately 1/20th of a pound.

30 blocks per pound: Each block would weigh approximately 1/30th of a pound.

40 blocks per pound: Each block would weigh approximately 1/40th of a pound.

Please note that the actual weight of each block may vary, and we are making estimates here.

Now, depending on the weight of each block, we can determine which option rounds to the nearest block.

For example, if the average weight of each block is 0.06 pounds, then:

10 blocks per pound would be closest to the actual weight, rounding to the nearest block.

Keep in mind that the actual weight of each block may differ, so this is just an example to demonstrate the calculation.

Step-by-step explanation:

75/5 is 15 and in order to start making a profit than you have to wash 16 cars

hope this helps

Answer:

Step-by-step explanation:

The idea is to find out after what number car washed will they begin to make money. That means that this is an inequality. If they charge $5 per car, and the number of cars is our uknown, then the expression for that charge is 5x. If they need to make more than what they spent on setting up, they want to make more than $75, which looks like this: > 75. Putting that together:

5x > 75 and solving for x,

x > 15.

That means that they have to wash 15 cars to just break even and starting on the 16th car on up, they will see a profit.

The difference in perimeters between the two squares is 2 inches.

Here, we have,

To find the difference in perimeters between two squares, we subtract the perimeter of the smaller square from the perimeter of the larger square.

Let's denote the side length of the larger square as S = 3/4 inch and the side length of the smaller square as s = 1/4 inch.

The perimeter of a square is given by the formula: P=4s, where s is the side length.

For the larger square with side length S = 3/4 inch, the perimeter P is:

P = 4 × 3/4

 =3 inches

For the smaller square with side length s = 1/4 inch, the perimeter p is:

p = 4 × 1/4  =1 inch

The difference in perimeters is then:

Difference = P - p

so, we get,

Difference

=P - p

=3−1

=2 inches

Therefore, the difference in perimeters between the two squares is 2 inches.

Option - B : Decision support system is a flexible tool for data analysis, since its reports do not have a fixed format.

  Decision support systems, a subset of business intelligence, are created to help organisations make sensible business decisions based on vast volumes of analysed data. Huge volumes of data are analysed using an interactive information system called a decision support system (DSS) to aid in the direction of business choices. A DSS aids management, operations, and planning levels of an organisation in making better decisions by assessing the importance of uncertainties and the tradeoffs involved in selecting one option over another. A DSS uses a variety of raw data, papers, personal knowledge, and/or business models to aid users in making decisions. A DSS may make use of relational data sources, cubes, data warehouses, electronic health records (EHRs), income projections, sales projections, and other sources.

Answer:

First Option {-2 , 0 , 2}

Step-by-step explanation:

A critical point occurs when the derivative is 0 or undefined.

The function in the question is undefined at x = 2 and at x = -2 because if we put x = 2 or x = -2 the denominator becomes 0 hence anything divided by 0 is undefined, and the derivative equals 0 at x = 0 so the critical points are

{-2 , 0 , 2}

Use the quotient rule to find the derivative of the function then equal it to zero

\(y=\frac{x^2-1}{x^2-4}\\\\\frac{dy}{dx}=\frac{(x^2-4)(2x)-(x^2-1)(2x)}{(x^2-4)^2}\\\\0=\frac{(x^2-4)(2x)-(x^2-1)(2x)}{(x^2-4)^2}\\\\0=2x^3-8x-2x^3+2x\\0=-6x\\x=0\)

A distance of 2 inches in the scale drawing represents 8 feet in the actual room.

let's first find the scale factor of the scale drawing. The actual room has a perimeter of 2(20 ft + 12 ft) = 64 feet. The scale drawing has a perimeter of 16 inches. Since there are 12 inches in a foot, we convert the perimeter of the actual room to inches: 64 ft × 12 in/ft = 768 inches.

Now, we find the scale factor by dividing the scale drawing's perimeter by the actual room's perimeter in inches: 16 in / 768 in = 1/48. This means that each inch in the scale drawing represents 48 inches (or 4 feet) in the actual room.

Since 2 inches on the scale drawing represents a certain distance in the room, we multiply 2 in by the scale factor (1/48) and convert to feet: 2 in × (1/48) × 12 in/ft = 8 ft.

(2, –3) is a solution to the system of linear equations.

Step-by-step explanation:

Given: Equations:

4x + y = 5 --------(2),

Add Equation (1) + Equation (2),

3x + 4x = 9 + 5

7x = 14  ( Combine like terms )

x = 2   ( Divide both sides by 7 ),

From equation 1:

3(2) - y = 9

6 - y = 9

-y = 9 - 6    ( Subtraction 6 on both sides )

-y = 3

y = - 3     ( Multiplying -1 on both sides )

Given the curve $r(t) = (5 cos(3t), 5 sin(3t), t)$ and we need to find its curvature at the point $t = 0$.

Curvature is the measure of how quickly a curve changes its direction as compared to a unit tangent vector. A curve has curvature $\kappa$ at a point if its tangent vector is rotating at a rate of $\kappa$ about that point.The formula for the curvature $\kappa$ of a curve $r(t)$ is$$\kappa = \frac{\|r'(t) \times r''(t)\|}{\|r'(t)\|^3}$$Now, let's find the tangent and normal vectors and the radius of curvature.

The tangent vector to the curve is given by$$\mathbf{T}(t) = \frac{r'(t)}{\|r'(t)\|}$$Substitute $r(t) = (5 \cos 3t, 5 \sin 3t, t)$ and simplify to find the unit tangent vector,$$\mathbf{T}(t) = \frac{r'(t)}{\|r'(t)\|} = \frac{(-15 \sin 3t, 15 \cos 3t, 1)}{\sqrt{225 \sin^2 3t + 225 \cos^2 3t + 1}} = (-3 \sin 3t, 3 \cos 3t, 1/\sqrt{225})$$

The normal vector to the curve is given by$$\mathbf{N}(t) = \frac{\mathbf{T}'(t)}{\|\mathbf{T}'(t)\|}$$Differentiate the tangent vector and simplify,$$\mathbf{T}'(t) = (-9 \cos 3t, -9 \sin 3t, 0)$$Substitute $\mathbf{T}'(t)$ and simplify to find the unit normal vector,$$\mathbf{N}(t) = \frac{\mathbf{T}'(t)}{\|\mathbf{T}'(t)\|} = (-\cos 3t, -\sin 3t, 0)$$

The binormal vector is given by$$\mathbf{B}(t) = \mathbf{T}(t) \times \mathbf{N}(t)$$Substitute $\mathbf{T}(t)$ and $\mathbf{N}(t)$ and simplify to find the unit binormal vector,$$\mathbf{B}(t) = \mathbf{T}(t) \times \mathbf{N}(t) = (-1/\sqrt{225}, 0, -3/\sqrt{225})$$The radius of curvature is given by$$\rho = \frac{1}{\kappa} = \left\|\frac{d\mathbf{T}/dt}{\kappa}\right\| = \left\|\frac{\mathbf{N}'(t)}{\kappa}\right\|$$

Differentiate the normal vector and substitute it to find the radius of curvature,$$\mathbf{N}'(t) = (-3 \sin 3t, 3 \cos 3t, 0)$$$$\left\|\frac{\mathbf{N}'(t)}{\kappa}\right\| = \left\|\frac{(-3 \sin 3t, 3 \cos 3t, 0)}{\frac{\|r'(t) \times r''(t)\|}{\|r'(t)\|^3}}\right\| = \frac{225}{14}$$Finally, we get the curvature at $t=0$,$$\kappa = \frac{\|r'(0) \times r''(0)\|}{\|r'(0)\|^3} = \frac{\|(-15, 0, 1)\times(-45, -45, 0)\|}{\|(-15, 0, 1)\|^3} = \frac{15}{\sqrt{226}}$$

Thus, the curvature of the curve $r(t) = (5 cos(3t), 5 sin(3t), t)$ at the point $t=0$ is approximately 1.18 (rounded to two decimal places).

Here, the given curve is $r(t) = (5 cos(3t), 5 sin(3t), t)$. To find the curvature of the curve, first we have to find the unit tangent vector to the curve. From the definition, we have $\mathbf{T}(t) = \frac{r'(t)}{\|r'(t)\|}$. We have to differentiate the unit tangent vector and the derivative of $\mathbf{T}(t)$ is called the principal normal vector $\mathbf{N}(t)$, which is given by $\mathbf{N}(t) = \frac{\mathbf{T}'(t)}{\|\mathbf{T}'(t)\|}$.

Finally, the curvature of the curve is given by $\kappa = \frac{\|r'(t) \times r''(t)\|}{\|r'(t)\|^3}$ and the radius of curvature is $\rho = \frac{1}{\kappa} = \left\|\frac{d\mathbf{T}/dt}{\kappa}\right\| = \left\|\frac{\mathbf{N}'(t)}{\kappa}\right\|$.

By substituting the value $t=0$ in the formula for curvature we get, $\kappa = \frac{\|r'(0) \times r''(0)\|}{\|r'(0)\|^3} = \frac{\|(-15, 0, 1)\times(-45, -45, 0)\|}{\|(-15, 0, 1)\|^3} = \frac{15}{\sqrt{226}}$. Thus, the curvature of the curve $r(t) = (5 cos(3t), 5 sin(3t), t)$ at the point $t=0$ is approximately 1.18 (rounded to two decimal places).
