Answer:

  c(t) = 105·1.07^t

Step-by-step explanation:

You want an exponential equation describing the cost of athletic shoes that are $105 now and whose cost is growing at 7% per year for t years.

The general form of the exponential equation is ...

  c(t) = a·b^t

where 'a' is the initial cost (105) and b is the growth factor. The growth factor is related to the given growth rate by ...

  b = 1 +r = 1 +7% = 1.07

Then the equation is ...

  c(t) = 105·1.07^t

As you stated, a convention is as follows: x, y, w, h; likewise, the origin of the picture is from top left, not really the bottom left, as indicated by your drawing. The clusters for top left the box's corner are x, y, and w, h.

Box Bounding In order to characterize the target position in object recognition, we often utilize a bounding box. Both x and y axis values there at upper-left corner as well as the x and y axes coordinates inside the bottom part of the rectangular define the bounding box, which is a rectangular box.

The x - axis and y axis values at the upper-left corner as well as the x and y axis values inside the bottom part of a rectangle define the bounding box, which is a rectangular box. Based on the image, we will create the bounding boxes for the dog and cat.

The equation of the line in slope-intercept form is y = 3x - 11.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know slope(m) = (y₂ - y₁)/(x₂ - x₁).

∴ Slope(m) = (- 5 + 8)/(1 - 0) = 3.

So, y = mx + b can be written as - 5 = 3(2) + b ⇒ b = - 11.

So, The required line is y = 3x - 11.

The required simplified expression is: x² - 9/ 9x⁴ + 9x² for all x ≠ 0 or 3.

The given expression below is:

x² - 9 / (3x²)(3x²) + 9x²

To simplify the given expression, we must first distribute the terms on the numerator and denominator.

The numerator becomes x² - 9 and the denominator becomes (3x²)(3x²) + 9x².

Next, we must simplify the denominator by combining like terms. The denominator becomes 9x⁴ + 9x².

Finally, we can simplify the entire expression by dividing the numerator by the denominator.

This gives us the simplified expression: x² - 9/ 9x⁴ + 9x².

Note that this expression is not defined when x = 0 or x = 3, as it would result in a division by zero.

Thus, the final simplified expression is x² - 9/ 9x⁴ + 9x² for all x ≠ 0 or 3.

The fraction of the distances of the points A(2·a + 3, 3·a + 4), and B(4 - a, 5 - a) from the x- and y-axis and the value of a > 5, indicates that the value of a is 16.[tex]\overline{4}[/tex]

A fraction is a representation of the amount a part of an item compared to the whole of the item.

The distance from the x-axis to the point A(2·a + 3, 3·a + 4) = 3·a + 4

The distance from the y-axis to the point B(4 - a, 5 - a) = 4 - a

Therefore; 1/5 of the distance from the x-axis to the point A(2·a + 3, 3·a + 4) is (1/5) × (3·a + 4)

6/7 of the distance from the y-axis to the point B(4 - a, 5 - a) is (6/7) × (4 - a)

The details in the question indicates; (1/5) × (3·a + 4) = (6/7) × (4 - a)

However, if a > 5, then 4 - a < 0, while (3·a + 4) > 0, from which we get;

If a > 5, then, (1/5) × (3·a + 4) = (6/7) × (a - 4)

[tex]\dfrac{1}{5} \times (3\cdot a + 4) = \dfrac{6}{7} \times (a -4)[/tex]

7 × (3·a + 4) = 5 × 6 × (a - 4)

21·a + 28 = 30·a - 120

30·a - 21·a = 9·a = 120 + 28 = 148

The expected value for Alison's investment is $650

A projected average value for an investment at some point in the future is known as the expected value (EV).

A anticipated value for an investment is called expected value (EV). It is determined by averaging all conceivable outcomes, multiplied by the likelihood that they will occur. The long-term average of random variables is known as EV. Additionally, it is the probability-weighted average of every potential value.

Given:

There is a 35% chance that she will make $4000.

25% chance that she will lose $3000.

and a 40% chance that she will break even (make $0).

The expected value can be calculated as:

= ∑ (Probability of event happening x Payoff if event happens)

So, The expected value  is

= (35% x 4000) + (25% x -(3,000)) + (40% x 0)

= 1400 -750+0

= $650

The value of x is 30 degrees and the value of y = 5

The total figure is divided in to two triangles

Consider the first triangles

All the angles of the triangles is equal that is 60 degrees, This is a equilateral triangles

In equilateral triangles all the sides will be equal

Then the equation will be

8y = 40

y = 40/8

y = 5

Then consider the second triangle

Here, two sides are 40 units and third side is different, therefore it is an isosceles triangle

Then the equation will be

x + x + (180-60) = 180

2x + 120 = 180

2x = 180 - 120

2x = 60

x = 60/2

x = 30 degrees

Therefore, the value of x and y are 30 degrees and 5 respectively

The percentage error when the weight was found to be 62.5 ounces is 3.2%.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

Since the the weight of the sample as 60.5 ounces and the true weight was found to be 62.5 ounces.

The percentage error will be:

Error / Initial value × 100

= (62.5 - 60.5) / 62.5 × 100

= 2 / 62.5 × 100

The possible solution to the condition is that if the rank of matrix A is less than the rank of its augmented matrix, the augmented matrix contains a row of the form 0 0…0 | b, where b is nonzero.

A matrix is a rectangular array or table with rows and columns of numbers, symbols, or expressions that are used to represent a mathematical object or an attribute of one.

Since the pivot b must, of course, not be zero, every row entry to the left of the pivot is zero by nature of the row-reduction procedure, which results in a row of the type,

Equation of the line passes through (10,2) and is perpendicular to the line y = 2x is given by  y = -x / 2 + 7.

As given in the question,

Given equation of the line :

y = 2x

Line passes through the point (x₁ , y₁ ) = (10, 2)

Standard form of slope intercept form

y = mx + c

'm' is the slope

slope of the given line 'm₁' = 2

let 'm₂' be the slope of the required line

Multiplication of the Slope of two perpendicular lines is given by :

m₁ × m₂ = -1

⇒2 × m₂ = -1

⇒m₂ = -1/2

Equation of the line perpendicular to the given line and passes through

(x₁ , y₁ ) = (10, 2)

Step-by-step explanation:

We can say that the view in which one or more faces of the object are not perpendicular to the rest of the faces, but are inclined projections, are the auxiliary views.

Initially, we must know that the views of an object or body are orthogonal projections associated with it.

In this sense, auxiliary views are a type of view that are characterized by arising from a change in projection plane, they are usually used when highly complex parts or objects must be represented.

From the question, we have the following parameters that can be used in our computation:

y = -x^2 + 50x - 80

Rewrite this function as

y = -x² + 50x - 80

Differentiate the function

So, we have

y = -2x + 50

Set to 0

-2x + 50 = 0

So, we have

2x = 50
