The value of delta such that the statement is true is:

δ = 0.0002

We want to find δ such that:

if |x -3| < δ, then |5x - 15| < ε

So we have two absolute value inequalities to work with.

With ε = 0.001

If we take the second inequality and replace epsilong, we will get:

|5x - 15| < 0.001

We can take 5 as a common factor on the left side to get:

5*|x - 3| < 0.001

Dividing both sides by 5 gives:

|x - 3| < 0.001/5

|x - 3| < 0.0002

Then the value of delta is 0.0002.

Solving a Single Variable Equation:

3.1 Solve : -3x2+5 = 0

Subtract 5 from both sides of the equation :

-3x2 = -5

Multiply both sides of the equation by (-1) : 3x2 = 5

Divide both sides of the equation by 3:

x2 = 5/3 = 1.667

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:

x = ± √ 5/3

The equation has two real solutions

These solutions are x = ±√ 1.667 = ± 1.29099

Step-by-step explanation:

To find the base of the exponential function F(x) = b^x, we need to use the information that its graph contains the point (1/3, 2). We can use this information to solve for b.

Since the graph passes through the point (1/3, 2), we can set x = 1/3 and y = 2 in the equation F(x) = b^x:

b^(1/3) = 2

Taking the cube root of both sides, we get:

b = (2)^3 = 8

So the base of the exponential function F(x) = b^x is b = 8, which means the correct answer is C) 8.

What is a scale factor?

A scale factor resembles a unit scale in several ways. It is a ratio that assesses the relationship between scale and real dimensions. Because it doesn't provide any specified units, it differs.

It is given that:

Width of the kitchen = 4 inches.

Length of the kitchen= 6 inches.

It is also given that the actual width of the house is equal to 20 feet.

Now we have to find the length of the house:

The proportion will be:

[tex]\frac{4}{6} =\frac{20}{Length} \\Length=\frac{20*6}{4} \\Length=30feet[/tex]

Answer:

The width of the living room is 10 feet.

Step-by-step explanation:

Let the width of the living room is w.

And the length of the room is 2w - 8 ft.

Given,

The area of the room is 192  feet^2, by using the formula of area of a rectangle we get,

A = l × w

192 = (2w - 8) × w

Now,

192 = 2w^2 - 8w                              ( By expanding)

200 = 2w^2                                     (By adding 8w to both sides)

100 = w^2                                        (Dividing both sides by 2)      

If we take square root on both sides,

w = 10

So,

The width of the living room is 10 feet.

0 = x^3/3 + 7x^2/2 + 10x + d

This is a cubic equation, so it can be solved using various methods such as factoring, completing the square, or using a numerical method such as the Newton-Raphson method. If the equation can be factored or the method used is numerical, there might be multiple possible values of d. If the method used is completing the square, there would be only one possible value of d.

To estimate the number of seventh-graders who attend summer camp, we can use the sample proportion of 30 out of 200 students.

Let's call the population proportion of seventh-graders who attend summer camp "p".

The sample proportion can be estimated as:

p = 30/200 = 0.15

To estimate the number of seventh-graders in the entire school who attend summer camp, we can multiply the population size by the sample proportion:

Estimated number of seventh-graders attending summer camp = p * population size = 0.15 * 780 = 117

The length of the arc that the tip of the pendulum travels is approximately 7 feet.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

We can use the formula for the length of an arc of a circle to find the length of the arc that the tip of the pendulum travels:

Arc length = (angle/360) x 2πr

where: angle = the central angle (in degrees or radians) that the arc subtends and r = the radius of the circle

First, we need to convert the angle from degrees and minutes to decimal degrees.

There are 60 minutes in a degree, so:

40°6' = 40 + 6/60 = 40.1 degrees

Now we can plug in the values:

Arc length = (40.1/360) x 2π(10 feet)

Arc length = 6.99 feet

Hence, the length of the arc that the tip of the pendulum travels is approximately 7 feet.

The surface area of hexagonal prism A is 9√3x² cm². We are given that hexagonal prism B is the image of hexagonal prism A after dilation by a scale factor of 2.

Therefore, all corresponding sides of prism A and prism B are in the ratio of 1:2. Let the side length of the base of hexagonal prism A be 'x'. Then, the side length of the base of hexagonal prism B is '2x'.

We know that the surface area of hexagonal prism B is 172 cm². Using the formula for the surface area of a hexagonal prism, we can write:

172 = 2(3√3)(2x)^2 + 6(2x)h

where h is the height of hexagonal prism B.

Simplifying this equation, we get:

172 = 24√3x² + 12xh

Dividing both sides by 12, we get:

14.33 = 2√3x² + h

Now, since hexagonal prism B is a dilation of hexagonal prism A by a scale factor of 2, the height of hexagonal prism A is half the height of hexagonal prism B. So, the height of hexagonal prism A is h/2.

Using the formula for the surface area of a hexagonal prism, we can write:

SA(A) = 2(3√3)x² + 6x(h/2)

Substituting h/2 for the height of hexagonal prism A, we get:

SA(A) = 2(3√3)x² + 3xh

Substituting 2√3x² + h/2 for h, we get:

SA(A) = 2(3√3)x² + 3x(2√3x² + h/2)

SA(A) = 6√3x² + 3√3x² + (3/2)xh

Substituting 2√3x² for h in the above equation, we get:

SA(A) = 6√3x² + 3√3x² + (3/2)x(2√3x²)

SA(A) = 9√3x²

We can use the formula for the future value of an annuity to find the amount you'll have in the account at the end of Year 6. An annuity is a series of equal payments made at equal intervals of time, and the future value of an annuity is the amount you'll have in the future if you invest those payments and earn a given rate of interest.

The formula for the future value of an annuity is:

FV = PMT * (((1 + r)^n - 1) / r)

where:

FV = future value of the annuity

PMT = annual payment amount

r = annual interest rate as a decimal

n = number of payments

In this case:

PMT = $1,500

r = 0.05

n = 6

Plugging in the values:

FV = $1,500 * (((1 + 0.05)^6 - 1) / 0.05)

FV = $1,500 * (1.328867 - 1) / 0.05

FV = $1,500 * 0.328867 / 0.05

FV = $1,500 * 6.577340

FV = $9,865.61

So, the amount in the account at the end of Year 6 will be $9,865.61. To find the last payment, we subtract this amount from the desired future value of $10,000:

$10,000 - $9,865.61 = $134.39

Therefore, your last payment will be $134.39.

Displacement is different from distance, which is the actual length of the path traveled by an object regardless of its starting and ending points.

i. The person's displacement from the starting point can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the person has walked a distance of 500 yards south and 300 yards west, which forms a right triangle. Therefore, the displacement can be calculated as the square root of (500^2 + 300^2) = 583.1 yards (rounded to the nearest hundredth).

ii. To be looking back at point A from point B, the person would have to look in the direction opposite to the direction in which they walked from A to B. Since the person first walked due south and then due west, the direction in which they would have to look to be looking back at point A is north-east. This can be calculated using trigonometry, where the tangent of the angle formed between the line connecting A and B and the due south line is equal to 300/500. Therefore, the angle formed is the arctangent of (300/500) = 31.39 degrees. However, the true bearing is measured from the north and therefore, the true bearing would be 360 - 31.39 = 328.61 degrees (rounded to the nearest hundredth).

This angle can be calculated as the arctangent of (500/300) = 59.04 degrees.

Answer: 12.8 cm

Step-by-step explanation:

Multiply 3.2 by the scale of 4 to get 12.8.

The graph of ordered pairs (0, -5), (1, -3), (2, -1), (3, 1) is given below.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is y=2x-5.

Substitute x=0, 1, 2, 3, 4, ..... in the equation y=2x-5, we get

When x=0,

y=-5

When x=1,

y=-3

When x=2,

y=-1

When x=3

y=1

So, the ordered pair is (0, -5), (1, -3), (2, -1), (3, 1) and so on.

Therefore, the graph of ordered pairs (0, -5), (1, -3), (2, -1), (3, 1) is given below.
