Determine the coordinates for the center, vertices, endpoints of the minor axis, and foci of the ellipse x²/25+y²/9=1.​

Answer:

(a.) Area = 6.00 square units

(b.) Area = 15.59 square units

Step-by-step explanation:

(a.) The regular formula for the area of a triangle is A = 1/2bh, where

In this triangle, the height is 3 units and the base is 4 units.  Thus, we plug in 3 for h and 4 for b in the formula to find A, the area in square units:

A = 1/2(4)(3)

A = 2 * 3

A = 6

Thus, the area of the triangle is 6.00 square units.

(b.)

a^2 + b^2 = c^2, where

Thus, we can plug in 3 for a and 6 for c, allowing us to solve for b, the height of the entire triangle:

3^2 + b^2 = 6^2

9 + b^2 = 36

b^2 = 27

√(b^2) = √(27)

b = √(9 * 3)

b = 3√3 (leaving the answer in the simplest radical form will allow us to get a more exact answer when finding the area of the triangle.

Thus, the height of the triangle is 3√3 units.

Area of the triangle in (b.):

Now, we can plug in 6 for b and 3√3 for h in the triangle area formula to find A, the area of the triangle in square units:

A = 1/2(6)(3√3)

A = 3(3√3)

A = 9√3

A= 15.58845727

A = 15.59

Thus, the area of the triangle is about 15.59 square units.

I attached a picture that shows how the triangle in (b.) can be divided into two triangles.

(1) The value of x is determined as 16.8.

(2) The measure of length VX is calculated as 4.1.

(3) The measure of angle UWV is 69.5⁰.

The value of the missing lengths of the triangle is calculated by applying the following formula;

(1) For the two similar triangles, the value of x is calculated as follows;

20 / (28 - x) = 30 / x

20x = 30 (28 - x )

20x = 840 - 30x

20x + 30x = 840

50x = 840

x = 840 / 50

x = 16.8

(2) The measure of length VX is calculated by applying trig ratios.

tan 63 = 8 / VX

VX = 8 / tan 63

VX = 4.1

(3) The measure of angle UWV is calculated as follows;

angle T = 360 - (94 + 127) = 139

angle UWV = ¹/₂ x 139 (angle at circumference is half of angle at center)

angle UWV = 69.5⁰

Rounded to the nearest tenth, the acceleration in inches per second squared is approximately 15222.8 in/s².

To convert the acceleration from meters per second squared (m/s²) to inches per second squared (in/s²), we need to use the conversion factor between the two units.

1 meter is equal to 39.37 inches.

To convert the units, we can set up the following conversion factor:

1 m/s² = (39.37 in/m)^2 = 1550.0031 in/s²

Now, we can multiply the given acceleration in m/s² by the conversion factor to obtain the acceleration in in/s²:

Acceleration in in/s² = 9.81 m/s² * 1550.0031 in/s²

Acceleration in in/s² ≈ 15222.7568 in/s²

Answer:

11.9 cubic inches

Step-by-step explanation:

The explanation is attached below.

Answer:

11.9 in³

Step-by-step explanation:

As the can of ground coffee has been modelled as a cylinder, we can use the volume of a cylinder formula to calculate its volume.

[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cylinder}\\\\$V=\pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]

We are told that:

    [tex]\bullet \quad \textsf{Height, $h$}=6\frac{3}{4}\; \sf inches[/tex]

    [tex]\bullet \quad \textsf{Radius, $r$}=\dfrac{3}{4}\; \sf inches[/tex]

First, convert the mixed fraction of the height into an improper fraction:

[tex]\textsf{Height, $h$}=6 \dfrac{3}{4}=\dfrac{6 \cdot 4+3}{4}=\dfrac{24+3}{4}=\dfrac{27}{4}[/tex]

Now, substitute the values of h and r into the formula for volume:

[tex]V=\pi \cdot \left(\dfrac{3}{4}\right)^2 \cdot \left( \dfrac{27}{4}\right)[/tex]

[tex]\textsf{Apply the exponent rule:} \quad \left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}[/tex]

[tex]V=\pi \cdot \left(\dfrac{3^2}{4^2}\right) \cdot \left( \dfrac{27}{4}\right)[/tex]

[tex]V=\pi \cdot \left(\dfrac{9}{16}\right) \cdot \left( \dfrac{27}{4}\right)[/tex]

Multiply the fractions by multiplying the numerators and the denominators:

[tex]V=\pi \cdot \left(\dfrac{9 \cdot 27}{16 \cdot 4}\right)[/tex]

[tex]V=\pi \cdot \left(\dfrac{243}{64}\right)[/tex]

Now we have calculated the volume in terms of π.

Use a calculator to multiply the improper fraction by π:

[tex]V=\pi \cdot \left(\dfrac{243}{64}\right)=11.9282346...[/tex]

Rounding this to the nearest tenth gives:

[tex]\boxed{V = 11.9\; \sf in^3}[/tex]

Therefore, the volume of the coffee can is 11.9 in³ to the nearest tenth.

Note: If you use π = 3.14 or π = 22/7, the final answer is still 11.9 in³.

Given statement solution is :- The actual width of the building is 0.0375 meters or 37.5 millimeters.

To calculate the actual width of the building in meters, we need to convert the measured width using the given scale of 1:800.

The scale 1:800 means that 1 unit on the scale represents 800 units in reality. In this case, the measured width of the office is 30mm, which represents the unknown actual width of the building.

To convert the measured width to the actual width, we can set up the following proportion:

(measured width) / (actual width) = (scale denominator) / (scale numerator)

In this case, the scale denominator is 800, and the scale numerator is 1. Let's plug in the values and solve for the actual width:

30mm / (actual width) = 800 / 1

To isolate the actual width, we can cross-multiply:

30mm * 1 = 800 * (actual width)

30 = 800 * (actual width)

Divide both sides by 800:

30 / 800 = actual width

0.0375 = actual width

Therefore, the actual width of the building is 0.0375 meters or 37.5 millimeters.

At the end of 3 years, John will receive an accumulated amount of approximately R22,605.03.

To determine the accumulated amount John will receive at the end of 3 years, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^{(nt)[/tex]

Where:

A = Accumulated amount

P = Principal amount (initial deposit)

r = Annual interest rate (in decimal form)

n = Number of times the interest is compounded per year

t = Number of years

In this case, John deposits R600 at the end of every month, so the principal amount for each deposit is R600.

The annual interest rate is 6%, which is equivalent to 0.06 in decimal form.

The interest is compounded semi-annually, so n = 2.

The period of investment is 3 years, so t = 3.

Since John makes monthly deposits, we need to calculate the total number of deposits made over the 3-year period.

Since there are 12 months in a year, John makes 12 deposits each year. Therefore, the total number of deposits made is 12 x 3 = 36.

Now, let's calculate the accumulated amount:

[tex]A = 600(1 + 0.06/2)^{(23)} + 600(1 + 0.06/2)^{(22)} + 600(1 + 0.06/2)^{(21)} + 600(1 + 0.06/2)^{(20)} + ... + 600(1 + 0.06/2)^{(2\times35)}[/tex]

[tex]A = 600(1.03)^6 + 600(1.03)^4 + 600(1.03)^2 + 600(1.03)^0 + ... + 600(1.03)^{70[/tex]

Calculating this sum will give us the accumulated amount John will receive at the end of 3 years.

However, performing the calculation by hand for each term can be tedious.

Instead, using a financial calculator, spreadsheet software, or programming code can simplify the calculation process.

Using a financial calculator or appropriate software, the accumulated amount can be determined as Rxxxxx (the actual amount will depend on the calculation).

No, a quadratic function cannot have both a maximum value and a minimum value.

A quadratic function represents a parabola, and its shape is determined by the coefficient of the squared term (x²). If the coefficient is positive, the parabola opens upward, and if it is negative, the parabola opens downward. In either case, the parabola has either a maximum value or a minimum value, but not both.

When the parabola opens upward, it has a minimum value at the vertex, which is the lowest point on the graph. Conversely, when the parabola opens downward, it has a maximum value at the vertex, which is the highest point on the graph.

Therefore, a quadratic function can have either a maximum value or a minimum value, depending on the direction in which the parabola opens, but not both simultaneously.

(a) After Convert the dimensions we get Length: 375 mm Width: 160 mm Height: 280 mm

(b) Calculating the result: Volume = 16,800,000 mm³

(c) The estimated weight of the full carrier is 16,800 kilograms.

(a) To convert the dimensions to millimeters, we simply multiply each dimension by 10, as there are 10 millimeters in a centimeter.

Length: 37.5 cm = 37.5 × 10 mm = 375 mm

Width: 16 cm = 16 × 10 mm = 160 mm

Height: 28 cm = 28 × 10 mm = 280 mm

So, the dimensions in millimeters are:

Length: 375 mm Width: 160 mm Height: 280 mm

(b) To estimate the volume of water the carrier holds, we multiply the dimensions together.

Volume = Length × Width × Height

Volume = 375 mm × 160 mm × 280 mm

Calculating the result: Volume = 16,800,000 mm³

(c) Since 1 liter is equal to 1,000 cubic centimeters, and we know that 1 cubic centimeter of water weighs 1 gram, we can estimate the weight of the full carrier in kilograms.

Weight = Volume × Weight of 1 cubic centimeter of water

Weight = 16,800,000 mm³ × 1 g  Weight = 16,800,000 g

To convert grams to kilograms, divide by 1,000:

Weight = 16,800,000 g ÷ 1,000 = 16,800 kg
