Find the equation of an ellipse satisfying the given conditions.
Foci: (-4, 0) and (4, 0); length of major axis: 14?

Answers

Answer 1

The equation of the ellipse is [tex]\frac{x^2}{49} + \frac{y^2}{65} = 1[/tex]

How to determine the ellipse equation?

The given parameters are:

Foci: (-4, 0) and (4, 0)Length of major axis = 14

The above means that:

c = 4 and

The semi-major axis, a = 7 i.e 14/2

Calculate b using

[tex]b = \sqrt{c^2 + a^2[/tex]

So, we have:

[tex]b = \sqrt{4^2 + 7^2[/tex]

[tex]b = \sqrt{65[/tex]

Square both sides

[tex]b^2 = 65[/tex]

The standard form of the ellipse is represented as:

[tex]\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1[/tex]

This gives

[tex]\frac{x^2}{7^2} + \frac{y^2}{65} = 1[/tex]

Evaluate

[tex]\frac{x^2}{49} + \frac{y^2}{65} = 1[/tex]

Hence, the equation of the ellipse is [tex]\frac{x^2}{49} + \frac{y^2}{65} = 1[/tex]

How do i solve 6/8 divided by 9/8?

Answers

Answer: 48/72, simplified version is 2/3.

Step-by-step explanation: To find the answer, you have to multiply. Keep 6/8 but flip 9/8. Your equation should look like this: 6/8 x 8/9. Multiply the numerators first. 6 times 8 is 48. Next, multiply the denominators. 8 times 9 is 72. You should have this fraction: 48/72. You can simplify that by finding the greatest common factor that 48 and 72 have, which is 24. Do this to simplify: 48/72 divided by 24/24. 48 divided by 24 is 2 and 72 divided by 24 is 3. You should now have this fraction: 2/3. You can no longer reduce, so that's the answer.

WHAT IS THE NUMBER BOND FOR 540 + 280 NUMBER BOND

Answers

541 + 279 = 820 is the number bond for the expression 540 + 280.

What is number bond?

A number bond is a simple addition sum that has become so familiar to a child that they can recognise it and complete it almost immediately, with recall as automatic as that of an entry from a multiplication table in multiplication. Number bonds are used in the teaching of mathematics at the primary school level.

When given the other two numbers, a child who "knows" this number bond should be able to instantly fill in any one of these three numbers if it were missing, without having to "work it out." Number bonds are frequently taught in sets whose sums are common round numbers like 10 or 20.

We can find the number bond by simply adding 1 to first term and subtracting 1 from 2nd term.

540 + 280 = 820

(540 + 1) + (280 -1) = 820

541 + 279 = 820

Thus, 541 + 279 = 820 is the number bond for 540 + 280.

A coordinate system in geometry is a method that employs one or more integers or coordinates to identify the precise placement of points or other geometrical objects on a manifold, such as Euclidean space. Pairs of integers called coordinates are used to locate a point or object on a two-dimensional plane. The position of a point on a 2D plane is described by two integers known as the x and y coordinates. a group of numbers that represent precise positions. Usually, there are two numbers in the figure. The front-to-back distance is represented by the first number, while the top-to-bottom distance is represented by the second number. like in (12.5), when there are 12 units below and 5 above.

Graph the linear inequality y < 3x using slope-intercept form.

Answers

Given inequality:

y < 3x

To graph it first, consider line:

y = 3x

Find two points on the line.

x = 0 ⇒ y = 3*0 = 0, so the point is (0, 0)x = 1 ⇒ y = 3*1 = 3, the point is (1, 3)

Now, plot the two points.

Next, draw a dashed line trough the two points. Dashed line because the line is not included into solution set, due to '<' sign.

The last step, shade the area below (to the right) the line. Below the line because 'y <' means 'y-values less than' which appears below the line.

Answer:

See attachment.

Step-by-step explanation:

Given linear inequality:

[tex]y < 3x[/tex]

When graphing inequalities, temporarily replace the inequality sign for the equals sign:

[tex]\implies y=3x[/tex]

Find two points on the line by substituting two values of x into the equation:

[tex]x=0 \implies y=3(0)=0 \implies (0, 0)[/tex]

[tex]x=1 \implies y=3(1)=3 \implies (1,3)[/tex]

When graphing inequalities:

< or > : dashed line.≤ or ≥ : solid line.< or ≤ : shade under the line.> or ≥ : shade above the line.

Therefore, to graph the given linear inequality:

Plot points (0, 0) and (1, 3).Draw a dashed straight line through the points.Shade under the dashed line.

On the unit circle, how many radians would the point (-1,0) pass if rotated counterclockwise until it first reaches (root3/2,-1/2)?

Answers

The radians that the point (-1,0) would pass if rotated counterclockwise until it first reaches (√3/2,-1/2) is 2π/3.

How do we get the radians?

When a point on the unit circle is rotated counterclockwise, it traces out an angle in radians. To find the number of radians that the point (-1,0) would pass if rotated counterclockwise until it first reaches (√3/2,-1/2), we can use the fact that the point (-1,0) corresponds to an angle of π radians on the unit circle, and the point (√3/2,-1/2) corresponds to an angle of 5π/3 radians on the unit circle.

To find the number of radians passed, we need to subtract the initial angle (π) from the final angle (5π/3), so (5π/3 - π) = 2π/3 radians.

Therefore, the point (-1,0) will pass 2π/3 radians when it is rotated counterclockwise until it first reaches (√3/2,-1/2)

A woodpecker can live 27 years, a swallow 3 times less, and a crow lives 45 years longer than a swallow. How many years can a crow live?

Answers

27/3=9
9+45=54 that’s all y need to do

Answer:

54 years

Step-by-step explanation:

If we want to know how to solve for the number of years a crow can live, we can use this equation:

(27 ÷ 3) + 45 =?

We can first solve for 27 divided by 3.

(27 ÷ 3) + 45 =?

9 + 45 =?

Now solve for 9 plus 45:

9 + 45 = 54

Therefore, if a woodpecker can live 27 years, a swallow 3 times less, and a crow 45 years longer than the swallow, we can say that a crow can live for 54 years.

a) Write 5.1 x 10¹ as an ordinary number.
b) Work out the value of (1.7 x 10¹) × (8.5 × 10-²)
Give your answer in standard form.

Answers

On solving the provided question we can say that ordinary number the answer is  1.495 x 10^0

What is an ordinary number?

An ordinary number, also known as a standard form number or a decimal number, is a number that is written in the familiar base-10 format, with a whole number part and a fractional part separated by a decimal point.

A) 5.1 x 10¹ as an ordinary number is 51.

B) To work out the value of (1.7 x 10¹) × (8.5 x 10-²), we first need to multiply the two numbers:

(1.7 x 10¹) × (8.5 x 10-²) = 1.7 x 8.5 x 10¹ x 10-² = 14.95 x 10-1

To express the answer in standard form, we need to move the decimal point to the left so that there is only one non-zero digit to the left of it. 14.95 x 10-1 is 1.495 x 10^0. So the answer is 1.495 x 10^0

Myra blended 24 oz of orange sherbet when making 5/8 of smoothie. How many ounces of orange sherbet are needed for one batch?

Answers

Answer: To find out how many ounces of orange sherbet are needed for one batch of smoothie, you can use the proportion of orange sherbet to the total amount of smoothie.

24 oz of orange sherbet / 5/8 of smoothie = x oz of orange sherbet / 1 batch of smoothie

To solve for x, you can cross-multiply and simplify:

(24 oz of orange sherbet) * (1 batch of smoothie) = (5/8 of smoothie) * x oz of orange sherbet

24 * 1 = 5/8 * x

24 = 5/8 * x

By multiplying both sides by 8/5,

x = 24 * 8/5

x = 38.4 oz

So, 38.4 ounces of orange sherbet are needed for one batch of smoothie.

Daniel takes out a 40-year $150,000 loan from his bank in 2020. The
quadratic equation that approximates the year/loan balance relationship is
y = -120x^2 - 2500x + 80,000, where x is the number of years and y is the
balance. In what year, will his loan balance be $21,480?

Answers

So on solving the provided question we can say that - the equation will be y = -120x^2 - 2500x + 80,000; x = 0 so, y = 80000

What is equation?

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

y = -120x^2 - 2500x + 80,000

x = 0

so, y = 80000
