The 14 seed packet needed to grow 21 tomatoes.

How many seed packets?

The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications.

Given that:

It is given that rubin grew 9 tomatoes with 6 seed packets.

The 9 tomatoes by the 6 seed packs that were necessary to grow them, resulting in 1.5 tomatoes per seed pack.

Divide 21 by this 1.5 to find the number of seed packs needed to grow 21 tomatoes, result  would be 14.

So, the 14 seed packet needed to grow 21 tomatoes.

Answer:

- 6x² -x⁴/6 -1 because 6x² is co effectient

Answer:

no solutions

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

equation of blue line is y = x + 2 , in slope- intercept form

with slope m = 1

equation of red line is y = x - 3 , in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes

then the blue and red lines are parallel.

the solution to the system is at the point of intersection of the 2 lines

since the lines are parallel then they do not intersect each other.

thus the system shown has no solution.

Answer:

events at A and B are independent because P(A)(B)≠P(A)

Answer:

See graph attached

Step-by-step explanation:

Our life is simple because the equation \(y=2x+2\) is already put in slope-intercept form.

This form is called slope-intercept because it states exactly what it's called: The number multiplied by \(x\) (the constant of proportionality, in this case, 2) is the slope - and the y-intercept is what is being added to the equation (in this case, also 2, since there is a +2 at the end.)

With this info, we can start graphing.

We know that the y-intercept is 2, meaning one point will be (0,2).

We also know that the slope is 2, meaning every time x increases by 1, y will increase by 2. So the next point is (1, 4), the next is (2, 6), and so on.

Hope this helped!

The dimensions of the room are approximately 5.87 meters by 7.63 meters.

Let's assume the width of the room is "x" meters.

According to the problem, the length of the room is 1.3 times the width, so the length would be 1.3x meters.

The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, the perimeter is given as 27 meters.

Perimeter = 2(length + width)

Substituting the values we know:

27 = 2(1.3x + x)

Simplifying:

27 = 2(2.3x)

27 = 4.6x

Dividing both sides by 4.6:

x = 27 / 4.6

x ≈ 5.87

The width of the room is approximately 5.87 meters.

To find the length, we can multiply the width by 1.3:

Length = 1.3 * 5.87 ≈ 7.63

The length of the room is approximately 7.63 meters.

Therefore, the dimensions of the room are approximately 5.87 meters by 7.63 meters.

The market equilibrium is the point where the demand and supply functions are equal

The producer's surplus at market equilibrium for a product is #105

The functions are given as:

\(p = 121 - x^2\)

\(p = x^2 + 6x + 65\)

Equate both functions

\(x^2 + 6x + 65 = 121 - x^2\)

Collect like terms

\(x^2 + x^2 + 6x + 65 - 121 = 0\)

Evaluate the like terms

\(2x^2 + 6x -56 = 0\)

Divide through by 2

\(x^2 + 3x -28 = 0\)

Expand

\(x^2 + 7x - 4x - 28 = 0\)

Factorize

\(x(x + 7) - 4(x +7)= 0\)

Factor out x + 7

\((x - 4)(x +7)= 0\)

Solve for x

x = 4 or x = -7

The number of units cannot be negative,

So, we have:

x = 4

Substitute 4 for x in \(p = 121 - x^2\)

\(p = 121 - 4^2\)

p = 105

Hence, the producer's surplus at market equilibrium for a product is #105

Work Shown:

Problem 19

The triangle up top is a 30-60-90 triangle. The short leg is opposite the smallest angle 30 degrees. Double the short leg to get the hypotenuse.

z = 2*9 = 18.

The long leg is found like so

\(\text{long leg} = (\text{short leg})*\sqrt{3}\\\\\text{long leg} = 9\sqrt{3}\\\\\)

These two formulas apply to 30-60-90 triangles only.

The long leg of the 30-60-90 triangle up top is the hypotenuse of the 45-45-90 triangle at the bottom.

For 45-45-90 triangles, we can say:

\(\text{hypotenuse} = (\text{leg})*\sqrt{2}\\\\\text{leg} = \frac{\text{hypotenuse}}{\sqrt{2}}\\\\\text{leg} = \frac{\text{hypotenuse}*\sqrt{2}}{2}\\\\\text{leg} = \frac{9\sqrt{3}*\sqrt{2}}{2}\\\\\text{leg} = \frac{9\sqrt{3*2}}{2}\\\\\text{leg} = \frac{9\sqrt{6}}{2}\\\\\)

This represents the lengths of x and y. For any 45-45-90 triangle, the two legs are the same length (the right triangle is isosceles).

--------------------------------

Problem 21

Focus on the 30-60-90 triangle up top.

The hypotenuse of 12 divides in half to get x = 12/2 = 6 as the short leg.

The long leg is \(6\sqrt{3}\)

This is also the leg of the 45-45-90 triangle down below. Therefore, we have \(y = 6\sqrt{3}\)

Multiply the leg by sqrt(2) to find the hypotenuse.

\(\text{hypotenuse} = \text{leg}*\sqrt{2}\\\\\text{z} = 6\sqrt{3}*\sqrt{2}\\\\\text{z} = 6\sqrt{3*2}\\\\\text{z} = 6\sqrt{6}\\\\\)

--------------------------------

Problem 23

Focus on the triangle on the right. This is a 45-45-90 triangle.

The hypotenuse is 15sqrt(2), which must mean each leg is 15 units long. Therefore, z = 15. The unmarked vertical leg is also 15 units long.

This vertical side is the leg of the 30-60-90 triangle on the left. It's the long leg.

\(\text{long leg} = (\text{short leg})*\sqrt{3}\\\\\text{short leg} = \frac{\text{long leg}}{\sqrt{3}}\\\\\text{short leg} = \frac{(\text{long leg})*\sqrt{3}}{3}\\\\\text{y} = \frac{15\sqrt{3}}{3}\\\\\text{y} = 5\sqrt{3}\\\\\)

Double this short leg to get the hypotenuse of the 30-60-90 triangle.

\(x = 2y\\\\x = 2*5\sqrt{3}\\\\x = 10\sqrt{3}\\\\\)

Question 19:

Question 21:

Question 23:

Step-by-step explanation:

A 45-45-90 triangle is a special right triangle where the measures of its sides are in the ratio 1 : 1 : √2.  Therefore, the formula for the ratio of the sides is b : b : b√2 where:

A 30-60-90 triangle is a special right triangle where the measures of its sides are in the ratio  1 : √3 : 2.  Therefore, the formula for the ratio of the sides is c: c√3 : 2c where:

Side z is the hypotenuse of a 30-60-90 triangle where the leg opposite the 30° angle measures 9 units. Therefore, c = 9.

\(\implies z=2c =2 \cdot 9=18\; \sf units\)

Therefore, the other leg of the same triangle (opposite the 60° angle) measures c√3 = 9√3 units.

Sides x and y are the congruent legs of a 45-45-90 triangle with hypotenuse measuring 9√3 units. Therefore b√2 = 9√3, so b = (9√6)/2.

\(\implies x=\dfrac{9 \sqrt{6}}{2}\; \sf units\)

\(\implies y=\dfrac{9 \sqrt{6}}{2}\; \sf units\)

Side x is the side opposite the 30° angle in a 30-60-90 triangle with a hypotenuse of 12 units. Therefore, 2c = 12 so c = 6.

\(\implies x=6\; \sf units\)

Therefore, the other leg of the same triangle (opposite the 60° angle) measures c√3 = 6√3 units.

Side y is one of the congruent legs of a 45-45-90 triangle where the other congruent leg measures 6√3 units.

\(\implies y=6\sqrt{3}\; \sf units\)

Side z is the hypotenuse of a 45-45-90 triangle where the congruent legs measure 6√3 units. Therefore b = 6√3.

\(\implies z=b\sqrt{2} = 6 \sqrt{3} \sqrt{2}=6\sqrt{6}\; \sf units\)

Side z is one of the congruent legs of a 45-45-90 triangle where the hypotenuse measures 15√2 units. Therefore, b√2 = 15√2, so b = 15.

\(\implies z=b=15\; \sf units\)

Side x is the hypotenuse of a 30-60-90 triangle where the leg opposite the 60° measures 15 units. Therefore, c√3 = 15, so c = 5√3.

\(\implies x=2c=2 \cdot 5\sqrt{3}=10\sqrt{3}\; \sf units\)

Side y is the side opposite the 30° angle in a 30-60-90 triangle where the hypotenuse measures 10√3 units. Therefore, 2c = 10√3, so c = 5√3.

\(\implies y=c=5\sqrt{3}\; \sf units\)

The quotient is 3x + 7, and the remainder is (28x + 9) / (x^2 - 3x).

A division is a process of splitting a specific amount into equal parts.

We have to find 3x³-2x²+7x+9 divided by x²-3x

3x³-2x²+7x+9 is the dividend and x²-3x is the divisor.

The steps to solve this are given below.

Step 1: Take the first digit of the dividend from the left. Check if this digit is greater than or equal to the divisor.

Step 2: Then divide it by the divisor and write the answer on top as the quotient.

Step 3: Subtract the result from the digit and write the difference below.

Step 4: Bring down the next digit of the dividend (if present).

Step 5: Repeat the same process.

Hence, the quotient is 3x + 7, and the remainder is (28x + 9) / (x^2 - 3x).
