Answer:

1 1/2 bags

Step-by-step explanation:

given 1/8 of a bag will fill up 1/12 of a garden box, i.e.

1/8 bag ------> fills 1/12 box   (rearrange this)

1/12 box ----> requires 1/8 bag

to find how many bags it takes to fill 1 box, we simply multiply both sides of this equation by 12 to get the unit rate of fill

( 1/12 ) x 12 box -----> requires (1/8) x 12  bags

1 box ------> requires 12/8 = 3/2 = 1 1/2 bags  (answer)

Answer:

y=4x-6

Step-by-step explanation:

The equation of the line is y=mx+c where m is the slope and c is the intercept.

To find the slope, take two points \((x_{1},y_{1})\) and \((x_{2},y_{2})\) and use the equation \(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\). Let's take (1,-2) and (2,2) as our two points:

\(m=\frac{2-(-2)}{2-1}=\frac{4}{1}=4\)

The y-intercept is where the line crosses the y-axis. We can see from the graph that the line crosses the y-axis at -6, therefore c= -6.

Now we can write the equation of this line: y=4x-6

Answer:

The answer is y=4x-6

Answer:

Step-by-step explanation:

How can we solve equations such as the cubic equation shown here?

   x3 − x2 – 4x + 4 = 0

There is an extremely complicated formula for solving cubic equations. Some calculators have this formula built in and therefore can be used to solve cubic equations.

We are going to learn how these equations can be solved by factorising. If the equation has solutions that are integers  a, b and c then we can factorise the equation as follows:

   x3 − x2 – 4x + 4 = (x − a)(x − b)(x − c) = 0

Multiplying the brackets together we see that the constant term, 4, must be the number we get when we multiply a, b and c together.

   abc = 4

All the solutions a, b and c must be factors of 4 so there are not many whole numbers that we need to consider.

We have only the following possibilities:

   ±1, ±2 and ±4

We’ll examine each of these numbers to find which ones are solutions of the equation.

   f(1) = 13 − 12 – 4×1 + 4 = 0                        1 is a solution

   f(−1) = (−1)3 − (−1)2 – 4×(−1) + 4 = 6    

   f(2) = 23 − 22 – 4×2 + 4 = 0                         2 is a solution

  f(−2) = (−2)3 − (−2)2 – 4×(−2) + 4 = 0        −2 is a solution

We have now found three solutions so we don’t need to try  4 and −4 as a cubic equation has a maximum of three solutions.

These three numbers give us the values of a, b and c and we can  factorise the equation.

   x3 − x2 – 4x + 4 = (x − 1)(x − 2)(x + 2) = 0

This method involves finding integers that are factors of ( can be divided into ) the constant term and then testing whether these integers are solutions of the equation.

Unfortunately we cannot assume that the solutions of a third degree equation are all integers.

However, if we can find one integer solution, lets say it is x = a then, by the remainder theorem , we know that (x − a) is a factor of the equation. We can find another factor, a quadratic factor,  by division. We can then solve the quadratic equation by using the formula for solving quadratics.

Example 1

Solve the equation x3 − 3x2 – 2x + 4 = 0

We put the numbers that are factors of 4 into the equation to see if any of them are correct.

   f(1) = 13 − 3×12 – 2×1 + 4 = 0                        1 is a solution

   f(−1) = (−1)3 − 3×(−1)2 – 2×(−1) + 4 = 2    

   f(2) = 23 − 3×22 – 2×2 + 4 = −4

   f(−2) = (−2)3 − 3×(−2)2 – 2×(−2) + 4 = −12

   f(4) = 43 − 3×42 – 2×4 + 4 = 12

   f(−4) = (−4)3 − 3×(−4)2 – 2×(−4) + 4 = −100

The only integer solution is x = 1. When we have found one solution we don’t really need to test any other numbers because we can now solve the equation by dividing by (x − 1) and trying to solve the quadratic we get from the division.

Now we can factorise our expression as follows:  

   x3 − 3x2 – 2x + 4 = (x − 1)(x2 − 2x − 4) = 0

It now remains for us to solve the quadratic equation.  

   x2 − 2x − 4 = 0

We use the formula for quadratics with a = 1, b = −2 and c = −4.

We have now found all three solutions of the equation x3 − 3x2 – 2x + 4 = 0. They are: eftirfarandi:

   x = 1

   x = 1 + Ö5

   x = 1 − Ö5

Example 2

We can easily use the same method to solve a fourth degree equation or equations of a still higher degree. Solve the equation f(x) = x4 − x3 − 5x2 + 3x + 2 = 0.

First we find the integer factors of the constant term, 2. The integer factors of 2 are ±1 and ±2.

   f(1) = 14 − 13 − 5×12 + 3×1 + 2 = 0                       1 is  a  solution

   f(−1) = (−1)4 − (−1)3 − 5×(−1)2 + 3×(−1) + 2 = −4

   f(2) = 24 − 23 − 5×22 + 3×2 + 2 = −4

   f(−2) = (−2)4 − (−2)3 − 5×(−2)2 + 3×(−2) + 2 = 0   we have found a second solution.

The two solutions we have found 1 and −2  mean that we can divide by x − 1 and x + 2 and there will be no remainder. We’ll do this in two steps.

First divide by x + 2

Now divide the resulting cubic factor by    x − 1.

We have now factorised

f(x) = x4 − x3 − 5x2 + 3x + 2 into

f(x) = (x + 2)(x − 1)(x2 − 2x − 1)  and it only remains to solve the quadratic equation

x2 − 2x − 1 = 0.  We use the formula with a = 1, b = −2 and c = −1.

Now we have found a total of four solutions. They are:

   x = 1

  x = −2

  x = 1 +

  x = 1 −

hopefully this helps!:)

Answer:

Which two equations represent the same function?

A) y = 2x – 7  and f(x) = 7 – 2x

B) 3x = y – 2  and f(x) = 3x – 2

C) f(x) = 3x2 + 5 and y = 3x2 + 5

D) None of the above

Show/Hide Answer

A) y = 2x – 7  and f(x) = 7 – 2x

Incorrect. These equations look similar but are not the same. The first has a slope of 2 and a y-intercept of −7. The second function has a slope of −2 and a y-intercept of 7. It slopes in the opposite direction. They do not produce the same graph, so they are not the same function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.

B) 3x = y – 2  and f(x) = 3x – 2

Incorrect. These equations represent two different functions. If you rewrite the first equation in terms of y, you’ll find the equation of the function is y = 3x + 2. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.

C) f(x) = 3x2 + 5 and y = 3x2 + 5

Correct. The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5.

D) None of the above

Incorrect. Look at the expressions that follow f(x) = and y =. If the expressions are the same, then the equations represent the same exact function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 +

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Answer:

Step-by-step explanation:

ere are two quadrilaterals that have matching angles but different side lengths:

1.Quadrilateral ABCD:

Angle A = 90 degrees, Angle B = 60 degrees, Angle C = 120 degrees, Angle D = 90 degrees

Side AB = 5 units, Side BC = 10 units, Side CD = 5 units, Side DA = 10 units

2.Quadrilateral PQRS:

Angle P = 90 degrees, Angle Q = 60 degrees, Angle R = 120 degrees, Angle S = 90 degrees

Side PQ = 3 units, Side QR = 6 units, Side RS = 3 units, Side SP = 6 units

Both of these quadrilaterals have the same angle measures (90 degrees, 60 degrees, and 120 degrees) but different side lengths. Therefore, they are similar but not congruent.

Answer:

see below

Step-by-step explanation:

y-intercept: (0,1)

rate of change: 2/3

Y-intercept: I found this because the y-intercept is when x=0, and where the line crosses through the y-axis.  So, we can see that the y-intercept is (0,1)

Rate of change: The rate of change is another word for slope, or rise/run, so we can see, from point (0,1), that the rise is 2 units up and 3 units to the right to another point where the line crosses a whole number point.

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
