The line which is symmetrical to y=10+3x+x^2 is x = 3/2.

We are given that;

The equation y=10+3x+x^2

Now,

The line of symmetry of a parabola is a vertical line that passes through the vertex of the parabola and divides it into two congruent halves. The equation of the line of symmetry is given by the x-coordinate of the vertex 1.

To find the vertex of a parabola that is given in standard form y = ax^2 + bx + c, you can use the formula 2:

x = -b / 2a

This formula gives you the x-coordinate of the vertex. The y-coordinate can be found by plugging this value into the original equation.

We can rewrite it in standard form by rearranging the terms:

y = -x^2 + 3x + 10

Now you can identify the values of a, b and c:

a = -1 b = 3 c = 10

Using the formula for the x-coordinate of the vertex, you get:

x = -b / 2a x = -(3) / (2 * -1) x = 3/2

Therefore, by symmetry the answer will be  x = 3/2.

The pressure exerted by the cube on the countertop is 23060 Pa.

We are given that;

Side of cube=30cm

Now,

The force is equal to the weight of the cube, which is the product of its mass and the acceleration due to gravity. To find the mass, you need to multiply the volume and the density of iron. The volume of a cube is the cube of its side, and the density of iron is about 7870 kg/m^3. The acceleration due to gravity is about 9.8 m/s^2. Therefore:

F = mass * gravity F = (volume * density) * gravity F = ((side)^3 * density) * gravity F = ((0.3 m)^3 * 7870 kg/m^3) * 9.8 m/s^2 F = 2075.4 N

The area is equal to the area of one face of the cube, which is the square of its side. Therefore:

A = (side)^2 A = (0.3 m)^2 A = 0.09 m^2

Now that you have the force and the area, you can plug them into the formula for pressure:

P = F / A P = 2075.4 N / 0.09 m^2 P = 23060 Pa

Therefore, by algebra the answer will be 23060 Pa.

The measure of each labeled angles in the rhombus are  ∠1 = 49°, ∠2 = 90°, ∠3 = 49° and ∠4 = 41°

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

The rhombus

By corresponding angles, we have

∠3 = 49°

∠1 = 49°

The diagonals of a rhombus bisect each other at right angles

So, we have

∠2 = 90°

Ths sum of angles in a triangle is 180

So, we have

∠4 = 180 - 90 - 49°

Evaluate

∠4 = 41°

The volume of the cylinder rounded to the nearest cm is,

V₁ = 9,646.1 cm³

We know the following:

Cylinder volume: V₁ = π r² h

Ball (sphere) volume: V₂ =4/3 π r³

where:

V - volume

r - radius of base of cylinder and diameter of ball

h - height of cylinder.

Here, We have,

D = 16 cm ⇒ r = 16 ÷ 2 = 8

π = 3.14

a) Since balls touch all sides of cylinder (as shown in image), it can be concluded that height of cylinder is equal to sum of diameters of 3 balls and that radius of base of cylinder is equal to radius of ball:

h = 3 × r = 3 × 16 cm = 48 cm

r = 8 cm

So,

V₁ = π r² h

V₁ = 3.14 × (8 cm)² × 48 cm

V₁ = 9,646.1 cm³

The y-intercept of the equation for the line of best fit would increase while the magnitude of the slope would decrease, if only the data from 2010 to 2016 are considered. Also, there would be a positive correlation because as the independent variable increases, the dependent variable increases.

In Mathematics and Statistics, a trend line is sometimes referred to as a line of best fit and it can be defined as a statistical tool which is commonly used in conjunction with a scatter plot, in order to determine whether or not there's any form of correlation (either positive or negative) between a given data.

Generally speaking, the line of best fit or trend line should be very close to the data points as much as possible.

By critically observing the scatter plot using the data from 2010 to 2016, we can logically deduce that the y-intercept of the equation for the line of best fit would increase while the magnitude of the slope for the line of best fit would decrease.  

Additionally, there would be a positive correlation from 2010 to 2016 because as the independent variable on the x-axis increases, the dependent variable on the y-axis increases simultaneously.

We can solve the inequality |x + 3| < 1 by considering two cases:

Case 1: x + 3 ≥ 0

If x + 3 ≥ 0, then the inequality simplifies to:

x + 3 < 1

Subtracting 3 from both sides gives:

x < -2

So the solution set for this case is -3 < x < -2.

Case 2: x + 3 < 0

If x + 3 < 0, then we have:

-(x + 3) < 1

Multiplying both sides by -1 (which reverses the direction of the inequality) gives:

x + 3 > -1

Subtracting 3 from both sides gives:

x > -4

So the solution set for this case is -4 < x < -3.

Combining the solution sets from both cases, we get:

-4 < x < -2

Therefore, the solution to the inequality |x + 3| < 1 is the open interval (-4, -2).

The scale factor of the dilation is: 3/2

Dilation is a transformation of an object which changes its size. if the dilated image is larger then it is called enlargement. If the dilated image is smaller it is called reduction.

If the dilation has the origin as the center of dilation, we can find points on the image formed by dilation by multiplying the coordinates of the original geometric object like triangle multiplying by the scale factor. For scale factor k, the transformation of the dilation is written as :  (x, y) → (k x, k y).

The scale factor ,k  = coordinate of image / coordinate of original

Given that Triangle ABC is dilated to create triangle A’B’C’ using point O as the center of dilation as shown in the figure

Now,

To find the length and width of the actual flower bed, we need to use the scale given in the problem. The scale is 1 in. : 2 ft., which means that 1 inch on the drawing represents 2 feet in real life. The length of the flower bed on the drawing is 8 inches, so the actual length is:

8 inches x 2 feet/inch = 16 feet

Similarly, the width of the flower bed on the drawing is 6 inches, so the actual width is:

6 inches x 2 feet/inch = 12 feet

To find the area of the actual flower bed, we can use the formula for area of a rectangle:

Answer:

In continuous exponential growth, the size of a population can be modeled by the formula:

P = P0 * e^(rt)

where:

P = final amount (1982 bacteria in this case)

P0 = initial amount (1900 bacteria in this case)

r = growth rate (the variable we're trying to find)

t = time (1.5 hours in this case)

First, let's isolate the variable r in the equation:

1982 = 1900 * e^(1.5r)

Dividing both sides by 1900 gives:

1982 / 1900 = e^(1.5r)

Taking the natural logarithm (ln) of both sides (since the natural logarithm is the inverse of the exponential function) gives:

ln(1982 / 1900) = 1.5r

Now, solve for r:

r = ln(1982 / 1900) / 1.5

Using a calculator to evaluate this, we get:

r ≈ 0.0224

Therefore, the hourly growth rate is approximately 0.0224 or about 2.24% per hour. This means the bacteria population is growing at a rate of about 2.24% every hour.

We have the piecewise function as

Therefore, we will use the corresponding equation for that interval, which is f(x) = 6x² + 2.

Now, substitute x = 6 into the equation to find the value of f(x):

f(6) = 6(6)² + 2

Let's denote the distance between Jim and the car as "d" (in feet), and the time elapsed after Jim spots the car as "t" (in seconds).

Given that no car travels faster than 90 feet/second on this road, we can establish the following relationship between distance, time, and speed:

d ≤ 90t

However, Jim has a camera that allows him to see up to 1,080 feet in either direction.

This means that the distance between Jim and the car should be within the range of the camera's visibility, which is 1,080 feet.

Therefore, the inequality representing the possible distances between the car and Jim for any period of time after he spots it is:

-1,080 ≤ d ≤ 1,080

Combining both inequalities, we have:
