Describe fully the graph which has equation x² + y² = 9​

To find the answer to this problem, you will need to use the Pythagorean Theorem.

What is the Pythagorean Theorem?

The Pythagorean Theorem is an equation that represents the summation of the sides of a right triangle.

a² + b² = c², where a is the shortest leg of the triangle, b is the longest leg and c is the hypothenuse.

You have been given a (12) and b (16)

First, plug your given information into the equation: 12² + 16² = c²

Next, simplify your equation by squaring both terms:

12² = 144

16² = 256

Then, add these two answers together: 144+ 256= 400

This leaves you with the equation: 400 = c²

To isolate the c as an individual term, take the square root of both sides:

          [tex]\sqrt{400} = \sqrt{c^{2} }[/tex]

The above equation leaves you with the answer 20 = c, which is the hypothenuse

After dividing 451 by 51, we get a quotient of 008 and a remainder of 43.

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.

The other operations are multiplication, addition, and subtraction.

On a fundamental level, counting the instances in which one number is included within another is one interpretation of the division of two natural numbers.

It's not necessary for this number to be an integer.

For instance, if 20 apples are distributed equally among 4 persons, each person will get 5 of them.

So, we have 451/51.

Now calculate as follows:

451/51

Quotient = 008

Remainder = 43

(Refer to the image attached below)

Therefore, after dividing 451 by 51, we get a quotient of 008 and a remainder of 43.

The value of a and b for the given polynomial function f(x)=(x-a)(x-b) are a= -1, 2 and b=2, -1.

A function is said to as polynomial when a variable in an equation, such as a quadratic equation or cubic equation, etc., has only positive integer exponents or non-negative integer powers. For instance, the polynomial 2x+5 has an exponent of 1. The zero polynomial function, linear polynomial function, quadratic polynomial function, and cubic polynomial function are the four most common types of polynomials in precalculus and algebra.

The ratio of heads to tails in the probability test is 2:1 or (D) 2/1.

A ratio is a relationship or comparison between two numbers belonging to the same unit in order to determine how much larger one number is than the other.

For instance, if a test result is 7 out of 10, the ratio of the number of points earned to the total number of points is 7:10.

So, we know that the coin is flipped 36 times in the probability test:

Head = 24

Tails = 36 - 24 = 12

The ratio of heads to Tails:

There are total amount of 108 quarters and 18 dimes in a jar.

Total refers to a whole or full amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.

There are six times more quarters than dimes in a jar of coins.

If x represents the dimes, then the number of quarters will be 6*x if there are 28.80 in total.

A dime is worth 10 cents. In terms of money, we have 10 times as many dime.

A quarter is equal to 25 cents. We have 6 times as many quarters, which is 150 times (6 x 25).

10x +150x = 28.80

160x = 28.80

x = 0.18 that is for coins it will be 10x

Clare's mistake is at the second step and the solution to the equation is -65/11.

In Mathematics, the distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a particular numerical value, the same result and output would be obtained as when each addend is multiplied respectively by the same numerical value, and the products are added together.

Based on the information provided above, we can logically deduce that Clare's mistake is at the second step because the product of 12 and 5 is equal to 60, rather than 72. Additionally, Clare did not distribute the negative sign to all the terms of the equation.

By applying the distributive property of multiplication to the given mathematical expression, we have the following:

12(5 + 2y) = 4y - (5 - 9y)

60 + 24y = 4y - 5 + 9y

60 + 24y = 13y - 5

24y - 13y = -5 - 60

11y = -65

y = -65/11

The gradient of this straight line through the points is 0.16.

The gradient of this lines simply means that it would require one (1) unit to use £0.16 worth of electricity.

Mathematically, the gradient of a straight line can be calculated by using this formula;

Gradient, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Gradient, m = (y₂ - y₁)/(x₂ - x₁)

From the information provided through this graph, we have the following data points:

Points on x-axis = (30, 100).

Points on y-axis = (4, 15).

Substituting the given points into the formula, we have the following;

Gradient, m = (15 - 4)/(100 - 30)

Gradient, m = 11/70

Gradient, m = 0.16

This ultimately implies that, £0.16 worth of electricity would require one (1) units to be used by David.

Given the logarithmic values as,

log₃ (t) = 5.44

log₃ (y) = 11.03

log₃ (z) = 7.74

Now, the value of the expression can be written as,

The total cost of the Television is $ 1201.68.

The governments collect a consumption tax known as a sales tax on purchasing goods and services. It is always expressed as a percentage of the Purchase cost of goods and services. Here

Here we have

Alexandra bought a television set for $ 1105 in Newyork  

The rate of sales tax = 8.75%

Therefore,

The total cost of Television = Cost of Television + sales tax  

As we know sales tax = 8.75%

=> tax on Television = 8.75% of 1105  

= [tex]\frac{8.75}{100} \times 1105[/tex]

= 0.0875 × 1105

Answer:

The equation of the line that passes through the point (-6, -7) and has a slope of 1/3 is:

x - 3y + 15 = 0

Step-by-step explanation:

The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

To find the equation of the line that passes through the point (-6, -7) and has a slope of 1/3, we can use the point-slope form of a line:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line and m is the slope of the line.

Plugging in the given values, we have:

y - (-7) = (1/3)(x - (-6))

Which simplifies to:

y + 7 = (1/3)x + 2

Multiplying both sides by 3, we have:

3y + 21 = x + 6

Subtracting 21 and 6 from both sides, we have:

3y - x - 15 = 0

Therefore, the equation of the line that passes through the point (-6, -7) and has a slope of 1/3 is:

x - 3y + 15 = 0
