The mass of a piece of metal that has a volume of 12.4 cubic centimeters.

We can set up a proportion with the given masses and volumes:

Mass ₁ / Volume ₁ = Mass ₂ / Volume ₂

We can choose any two sets of masses and volumes from the table to use in the proportion. Let's use the first set of masses and volumes:

2.5 / 2.5 = Mass₂  / 12.4

We can solve for Mass 2 by cross-multiplying and simplifying:

The resistance of 1800 feet of the same sort of wire with a 0.45in diameter is roughly 15037.45 ohms.

Let R be the resistance of the wire,

L be the length of the wire,

d be the diameter of the wire, and

k be a constant of variation.

Then we have the equation:

R = k * L / d^2

Solving for k to find the resistance of a wire of varying length and diameter.

We can create an equation using the information provided:

15611 = k * 700 / 0.2^2

Solving for k, we get:

Answer:

I did the math in my head but please please trust me

It’s below

Step-by-step explanation:

C = 1 1/2

B = 2

A = 5

I’m going to try to explain as best as I can

First solve for C by subtracting the other numbers in its line going up to down from 9:

9 - 3 1/2 + 4 = C

9 - 7 1/2 = C

1 1/2 = C

now that w have C we can solve for b doing same steps:

9 - 5 1/2 + 1 1/2 = b

9 - 7 = b

2 = b

now we do A:

9 - 2 + 2 = a

9 - 4 = a

5 = a

Answer

A should be 5

B should be 2

c should be

[tex] 1\frac{1}{2 \\ } [/tex]

all should add up to 9

2+A(5)+b(2)= 9

a(5)+3 1/2+ 1/2=9

To calculate the weighted mean, first multiply each number by its corresponding weight, then add-up the products and divide by the sum of the weights-

weighted mean = (1 x 0.1 + 2 x 0.2 + 3 x 0.3 + 4 x 0.4) / (0.1 + 0.2 + 0.3 + 0.4)

Then simplifying the numerator:-

weighted mean = (0.1 + 0.4 + 0.9 + 1.6) / (0.1 + 0.2 + 0.3 + 0.4)

Then adding up the numerator:-

So the weighted mean of the numbers 1, 2, 3, and 4 with weights 0.1, 0.2, 0.3, and 0.4 respectively is 3.

The value of x after solving the given equation (6x+30) = 2x is equal to -7.5.

To solve for x in the equation (6x+30) = 2x, we need to isolate x on one side of the equation.

First, we can simplify the equation by subtracting 2x from both sides:

(6x+30) - 2x = 0

Simplifying this further gives:

4x + 30 = 0

To isolate x, we can subtract 30 from both sides:

4x = -30

Finally, we can solve for x by dividing both sides by 4:

x = -7.5

Therefore, the value of x in the equation (6x+30) = 2x is -7.5.

In general, when solving linear equations such as this, we want to manipulate the equation in such a way that we can isolate the variable on one side of the equation.

This can involve adding or subtracting terms, multiplying or dividing by constants, or taking square roots, among other techniques. The goal is to get the equation into a form that allows us to solve for the variable by itself.

The table can be complete based on the function given by substituting as:

When s = 4, M(s) = 7

When s = 9, M(s) = 12

Given a function,

In this diagram, A represents the launch pad, B represents the maximum altitude of the rocket, C represents the position of the photographer, and θ represents the angle at which the tripod should be set.

We want to find θ.

First, we can find the height of the triangle ABC using the Pythagorean theorem:

AC² = 200² - 50²

AC = √(200² - 50²)

AC = 190.526 ft

tan(θ) = opposite/adjacent = AB/BC = 200/50 = 4

Answer:

a) y = -2x + 3

b) y = -3x + 7

c) y = -1/2x + 4

d) y = 2

Step-by-step explanation:

Gradient is also known as slope

a) y = mx + b

3 = (-2)0 + b

b = 3

y = -2x + 3

b) y = mx + b

1 = (-3)(2) + b

1 = -6 + b

b = 7

y = -3x + 7

c) Slope m = (y2 - y1)/(x2 - x1)

m = (2 - 3)/(4 - 2) = -1/2

y = mx + b

3 = -1/2(2) + b

3 = -1 + b

b = 4

y = -1/2x + 4

d) The x‐axis or any line parallel to the x‐axis has a slope of 0.

y = mx + b

2 = -3(0) + b

b = 2

y = 2

Answer:

a) The equation of this line is y = -2x + 3

b) The equation of this line is y = -3x + 7

c) The equation of this line is y = -1/2x + 4 or y = -0.5x + 4

d) The equation of this line is y = 2

Step-by-step explanation:

The equation of a line can be written in the form y = mx + c, where m is the gradient and c is the y-intercept.

a) The equation of the line with a gradient of -2 and cutting the y-axis at 3 can be found using the point-slope form of a linear equation. The point-slope form is given by y - y1 = m(x - x1), where m is the gradient and (x1, y1) is a point on the line. Substituting m = -2 and (x1, y1) = (0, 3), we get:

y - 3 = -2(x - 0)

Simplifying the right-hand side gives:

y - 3 = -2x

Adding 3 to both sides gives the final equation:

y = -2x + 3

b) The equation of the line with a gradient of -3 and passing through the point (2, 1) can be found using the point-slope form again. Substituting m = -3 and (x1, y1) = (2, 1), we get:

y - 1 = -3(x - 2)

Simplifying the right-hand side gives:

y - 1 = -3x + 6

Adding 1 to both sides gives the final equation:

y = -3x + 7

c) To find the equation of the line passing through the points (2, 3) and (4, 2), we first need to find its gradient. The gradient is given by:

m = (y2 - y1)/(x2 - x1)

Substituting the coordinates of the two points, we get:

m = (2 - 3)/(4 - 2) = -1/2 or -0.5

Now, we can use the point-slope form again, this time with (x1, y1) = (2, 3) and m = -1/2:

y - 3 = (-1/2)(x - 2)

Simplifying the right-hand side gives:

y - 3 = (-1/2)x + 1

Adding 3 to both sides gives the final equation:

y = (-1/2)x + 4 or y = -0.5x + 4

d)The line is parallel to the x-axis and passes through the point (-3 ; 2). A line parallel to the x-axis has a gradient of 0. The general equation of a line is y = mx + c, where m is the gradient and c is the y-intercept. Since the gradient is 0, the equation becomes y = c. Since the line passes through the point (-3 ; 2), we can substitute y = 2 into the equation to find that c = 2. Therefore, the equation of this line is y = 2.

The mass of the trunk of the sequoia tree is 141443.1 kg.

The volume of a cylinder, using the formula:

V = πr²h

π is pi (approximately 3.14)

r is the radius of the trunk (which is half the diameter)

h is the height of the trunk

1 meter = 3.28084 feet

we can convert the given measurements from feet to meters to ensure consistent units.

The base diameter of the tree is 12.2 meters / 3.28084 = 3.719 meters,

so the radius is 3.719 / 2 = 1.8595 meters.

The height of the tree is 95 meters / 3.28084 = 28.9568 meters.

Therefore, the volume of the trunk is:

V = π(1.8595)²(28.9568) = 314.318 cubic meters

Now calculate the mass of the trunk by multiplying the volume by the density of the wood:

The polar curve R = 2cos(3θ) is symmetric about the x-axis, with three petals that extend from θ = 0 to θ = π/3, π to 4π/3, and 5π/3 to 2π. To find the area inside the curve, we need to integrate the expression for the area element in polar coordinates over the desired region:

dA = (1/2) [tex]R^{2}[/tex] dθ

The limits of integration for θ are from α = -6π to β = 6π, since we want to find the total area inside the curve for three full rotations. Thus, the integral for the area is:

A = ∫(β=6π, α=-6π) (1/2) [tex]R^{2}[/tex]dθ

To calculate the area of the shaded shape, we need to first find the area of the two rectangles and then subtract the overlap.

The area of the rectangle with dimensions 5m and 13m is:

Area = 5m x 13m = 65 square meters

The area of the rectangle with dimensions 9m and 11m is:

Area = 9m x 11m = 99 square meters

To find the overlap, we need to calculate the width of the shaded region. We can do this by subtracting the length of one rectangle from the other:

13m - 9m = 4m

So the width of the shaded region is 4m.

Now we can find the area of the shaded region by multiplying the width by the length:

Area = 4m x 5m = 20 square meters

Finally, we can find the total area by subtracting the overlap from the sum of the two rectangle areas:

Total Area = (65 + 99) - 20 = 144 square meters

Therefore, the area of the shaded shape is 144 square meters.

Step-by-step explanation:

in what form do you need the equation ?

I assume it is the slope-intercept form :

y = ax + b

"a" being the slope of the line, "b" being the y-intercept of the line.

the slope of a line is the ratio

y-coordinate difference / x-coordinate difference

when going from one point on the line to another.

and the y-intercept (y-axis intercept, to be precise) is the y-value when x = 0.

so, starting with the slope, we go for example from (1, 6) to (6, 1) :

x changes by +5 (from 1 to 6).

y changes by -5 (from 6 to 1).

so, the slope is

-5/+5 = -1

so, we know, our equation looks like

y = -x + b

to get "b" we use one of the points, e.g. (1, 6) :

6 = -1 + b

b = 7

and our final equation is

y = -x + 7
