Answer:

Step-by-step explanation:

Ok so, as given in the table, the cost of the 3rd tank is 800$, we can thus determine the cost of 1 cubic inch for a tank and use that to determine the cost of the other tanks.

[tex]volume =L\times W\times H\\=24\times 24\times 24\\=13824 in^3[/tex]

thus, to compute the cost of one cubic inch, we can divide the cost by the volume of the 3rd tank (in cubic inches)

[tex]\frac{800}{13824}=0.0579[/tex] [tex]usd/in^3[/tex]

now, we can determine the dimensions of the second tank that will make it cost 150$

[tex]0.0579\times 18\times W\times 24=150[/tex]

[tex]W=\frac{150}{0.0579\times 18\times 24} =6 in.[/tex]

Now to determine the cost of the first tank, we can multiply its volume by the cost per cubic inch:

[tex]cost=0.0579\times36\times 36\times 36=2700[/tex]$

As of question B, the cost will increase as the width increases.

For Question C, we can find the volume of the sphere by the formula:

[tex]volume=\frac{4}{3}\pi r^3 =\frac{4}{3}\pi \times 24^3=57905 in^3[/tex]

To find the cost of that tank, we just multiply its volume by the cost per unit volume:

[tex]cost=57905\times 0.0579=3352[/tex]$ (roughly)

The container is indeed big enough to store 560 sugar cubes.

To determine if the container is big enough to store 560 sugar cubes, we need to calculate the volume of the container and compare it to the total volume occupied by the sugar cubes.

The volume of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width, and h is the height.

In this case, the dimensions of the container are:

Length (l) = 6 inches

Width (w) = 4 inches

Height (h) = 3 inches

Using the formula, the volume of the container is calculated as follows:

V = 6 inches * 4 inches * 3 inches

V = 72 cubic inches

Now, let's calculate the volume occupied by a single sugar cube:

The side length of a sugar cube is 0.5 inches, so the volume of a single sugar cube is:

V_cube = 0.5 inches * 0.5 inches * 0.5 inches

V_cube = 0.125 cubic inches

To determine the number of sugar cubes that can fit in the container, we divide the volume of the container by the volume of a single sugar cube:

Number of sugar cubes = V_container / V_cube

Number of sugar cubes = 72 cubic inches / 0.125 cubic inches

Number of sugar cubes = 576

Since the number of sugar cubes that can fit in the container is 576, which is greater than the required 560 sugar cubes, we can conclude that the container is indeed big enough to store 560 sugar cubes.

Therefore, the container can comfortably accommodate the desired quantity of sugar cubes while providing a tight seal to keep ants away.

Based on the ratio of the digit in its hundred places compared to the same digit in its hundredth place, the number of times the value of the digit in the hundred places is greater than the value of the digit in the hundredth place is 10,000.

The ratio is the relative size of one value, number, or quantity compared to another.

The ratio is computed as the quotient of one quantity divided by another.

We can express a ratio as a fraction, decimal, percentage, or in its standard form (:).

For instance, using the digit 4 in its hundred places will give 400.  The same digit in its hundredth place gives 0.04.

The ratio of 400 to 0.04 = 10,000 (400 ÷ 0.04)

Thus, in this instance, we can conclude that 400 is 10,000 times greater than 0.04.

The equation of the circle with a center at (-4, 6) and a point on the circumference at (-2, 9) is (x + 4)² + (y - 6)² = 13.

Given:

Center of the circle: (-4, 6)

Point on the circumference: (-2, 9)

The center of the circle (h, k) is given as (-4, 6), which means h = -4 and k = 6.

The formula for the distance between the center and the point on the circumference can be used to determine the radius (r).

The formula for distance is provided by:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

where (x₁, y₁) is the center (-4, 6), and (x₂, y₂) is the point on the circumference (-2, 9).

Putting in the values:

d = √((-2 - (-4))² + (9 - 6)²)

= √((2)² + (3)²)

= √(4 + 9)

= √13

So, the radius (r) is √13.

Now, we can substitute the values of h, k, and r into the general equation of the circle:

(x - h)² + (y - k)² = r²

(x - (-4))² + (y - 6)² = (√13)²

(x + 4)² + (y - 6)² = 13

Therefore, the equation of the circle is (x + 4)² + (y - 6)² = 13.

To calculate the perimeter and area of a triangle, we need to know the coordinates of its vertices.

Let's calculate the perimeter and area for the given triangles.

a) Triangle with vertices A(2,2), B(7,-1), C(3,-8)

To calculate the perimeter, we need to find the lengths of the three sides of the triangle and sum them up.

Side AB:

Length AB = √((x2 - x1)² + (y2 - y1)²)

= √((7 - 2)² + (-1 - 2)²)

= √(5² + (-3)²)

= √(25 + 9)

= √34

Side BC:

Length BC = √((x2 - x1)² + (y2 - y1)²)

= √((3 - 7)² + (-8 - (-1))²)

= √((-4)² + (-7)²)

= √(16 + 49)

= √65

Side AC:

Length AC = √((x2 - x1)² + (y2 - y1)²)

= √((3 - 2)² + (-8 - 2)²)

= √(1² + (-10)²)

= √(1 + 100)

= √101

Perimeter = AB + BC + AC

= √34 + √65 + √101

To calculate the area, we can use the formula for the area of a triangle:

Area = 1/2 x base x height

We can consider any side of the triangle as the base and find the height corresponding to that base.

Let's consider side AB as the base.

Height h = distance between point C and the line AB

Using the formula for the distance between a point (x0, y0) and a line Ax + By + C = 0:

h = |(Ax0 + By0 + C)| / √(A² + B²)

Equation of line AB:

(x2 - x1) (y - y1) - (y2 - y1)(x - x1) = 0

(7 - 2)(y - 2) - (-1 - 2)(x - 2) = 0

5(y - 2) + 3(x - 2) = 0

5y - 10 + 3x - 6 = 0

5y + 3x - 16 = 0

Plugging in the coordinates of point C (3, -8):

h = |(53 + 3(-8) - 16)| / √(5² + 3²)

= |-5| / √(25 + 9)

= 5 / √34

Area = 1/2 x AB x h

= 1/2 x √34 x (5 / √34)

= 1/2 x 5

= 2.5

DC and DE are tangents to the circle at C and E respectively A is the centre of the circle B lies on the circle and BAE is a straight line L N

7.2.1: AABC is parallel to ADEC (AABC|||ADEC).

7.2.2: This completes the proof of both statements:

AABC|||ADEC and AE · EC = BC · DE.

To prove that AABC is parallel to ADEC, we can make use of the properties of tangents and alternate angles.

Proof:

AABC|||ADEC

DC and DE are tangents to the circle at C and E, respectively.

BAE is a straight line.

To prove AABC|||ADEC, we need to show that the alternate interior angles are congruent.

First, let's consider angle AED and angle ABC.

These angles are alternate interior angles formed by transversal AE intersecting the lines DE and BC.

Since DE is a tangent to the circle at E, angle AED is a right angle (90 degrees).

We know that a tangent to a circle is perpendicular to the radius at the point of tangency.

angle AED = 90 degrees.

Let's consider angle ABC. Since DC is a tangent to the circle at C, angle ABC is also a right angle (90 degrees).

Again, this follows from the property that a tangent is perpendicular to the radius at the point of tangency.

Since both angle AED and angle ABC are right angles, they are congruent:

angle AED = angle ABC.

By the alternate interior angle if two lines are intersected by transversal and the alternate interior angles are congruent, then the lines are parallel.

AABC is parallel to ADEC (AABC|||ADEC).

7.2.2 Showing that AE · EC = BC · DE

To prove that AE · EC = BC · DE, we can use the fact that AABC is parallel to ADEC.

Since AABC is parallel to ADEC, we can apply the intercept theorem or the proportionality theorem.

According to the intercept two parallel lines intersect a set of parallel lines, then the segments formed on one transversal are proportional to the corresponding segments formed on any other transversal.

Using the intercept theorem, we can write the following proportion:

AE/BC = DE/EC

To find AE · EC, we can cross-multiply the proportion:

AE · EC = BC · DE

We have shown that AE · EC is equal to BC · DE.

Third angle = 180° - (64° + 32°)

Third angle = 84°

To find the length of the third side, which is opposite the angle of 84°, we can use the Law of Sines.

The Law of Sines states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides of a triangle.

Let's label the triangle with angles A, B, and C, and sides a, b, and c, respectively.

In this case, angle A is 84°, angle B is 64°, and angle C is 32°. Side a is the side opposite angle A, side b is the side opposite angle B, and side c is the side opposite angle C.

Using the Law of Sines, we have the following equation:

sin(A) / a = sin(B) / b = sin(C) / c

We want to find the length of side a, so we can rearrange the equation as follows:

sin(A) / a = sin(B) / b

Now we can substitute the given values:

sin(84°) / a = sin(64°) / 30

To find side a, we can solve for it algebraically:

a = (sin(84°) × 30) / sin(64°)

Calculating this expression, we get:

a ≈ 30.1

Therefore, the length of the third side, which is opposite the angle of 84°, is approximately 30.1 units.
