In the diagram, a circle centered at the origin, a right triangle, and the Pythagorean theorem are used to derive the equation of a circle, x2 + y2 = r2.

On a coordinate plane, circle Q is centered at the origin with radius r. Triangle P Q S is shown. Point Q is at (0, 0) and points P is at (x, y). The length of Q P is r, the length of P S is y, and the length of Q S is x. Angle P S Q is a right angle.

If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle, which could represent the equation of the new circle?

(h + x)2 + (k + y)2 = r2
(x – h)2 + (y – k)2 = r2
(k + x)2 + (h + y)2 = r2
(x – k)2 + (y – h)2 = r2

Answers

Answer 1

Based on the given information, the equation of this new circle is B. (x - h)² + (y - k)² = r²

What is the equation of a circle?

The equation of a circle of radius r represents all the points that lie on the circumference of the given circle.

The equation of a circle is:

x² + y² = r²

Where:

r is the radius of a circle.

After translating h units along the x-axis and k units along the y-axis on a coordinate plane,

The equation of this new circle is given by:

(x - h)² + (y - k)² = r²

Where h and k represent the coordinates at the center.

Thus, option B is correct.

To factor the expression 3x2 – 9x, Caleb found the GCF as shown.

List the factors:
3x2 = 3 • x • x
9x = 3 • 3 • x
GCF = 3 • 3 • x • x = 9x2
What is Caleb’s error?

Answers

Answer:

Caleb’s error was :

instead of selecting the least exponent ,Caleb took the highest exponent.

Step-by-step explanation:

3x² = 3 • x • x

(in this factorization the exponent of 3 is 1 and the exponent of x is 2)

9x = 3 • 3 • x

(in this factorization the exponent of 3 is 2 and the exponent of x is 1)

• The common factors of 3x² and 9x are 3 and x

In order to determine the GCF ,we have to Compare the exponents of the  common factors then take the numbers which have the least exponent value.

• in the factorization of 3x² the exponent of 3 is 1

and in the factorization of 9x the exponent of 3 is 2

The least exponent is 1 Then we take it.

• in the factorization of 3x² the exponent of x is 2

and in the factorization of 9x the exponent of x is 1

The least exponent is 1 Then we take it.

Conclusion:

GCF(3x² , 9x) = 3¹ × x¹ = 3x

The product of two consecutive positive integers is 194 more than the next integer. What is the largest of the three integers?​

Answers

Answer:

16

Step-by-step explanation:

let x be a positive integer

mathematically, the statement: “The product of two consecutive positive integers is 194 more than the next integer” means  x(x + 1) - 194 = x + 2

………………………………

Solving the equation x(x + 1) - 194 = x + 2 for x :

x(x + 1) - 194 = x + 2

⇔ x² + x - 194 = x + 2

⇔ x² - 194 = 2

⇔ x² = 196

⇔ x = 14 or x = -14

Since -14 < 0 then the solution to our equation is x = 14

Therefore

The largest integer of the three is x + 2 = 14 + 2 = 16

Verification:

14 × 15 − 194 = 210 − 194 = 16

Answers

By the Congruent Supplements Theorem, we can conclude that,

∠FBC ≅ ∠DBG.

What is Congruent Supplements Theorem?

The Congruent Supplements Theorem states that two angles are said to be congruent if they are supplements of the same angle or even congruent angles.

If there are 4 lines such that, right angles are created when a horizontal line with the points F, B, and G crosses a vertical line with the points A, B, and E at point B. Between angles F and B and A and G, a third diagonal line with the points D, B, and C is intersecting the other two lines at point B. At points A, C, and G, there is a fourth line that joins three other lines.

Drawing Conclusion

In case the angle FBC and angle CBG are supplementary angles, angle DBG and angle DBF are another pair of supplementary angles, and angle CBG is-congruent-to angle DBF, we can apply congruent supplement theorem and draw the following inference,

The truth of the given function that we have here is  The function increases at a constant multiplicative rate.

How to solve for the multiplicative rate of the constant

The table is given as

x            0   1    2      3

f(x)         2   3   4.5   6.75

We have x ranging from 0 to 3 while y ranges from 2 to 6.75.

The observations that we can make about the y values is that they produce the next value at the same rate of multiplication.

This is shown here

2 x 1.5 = 3

3 x 1.5 = 4.5

4.5 x 1.5 = 6.75

Hence we can conclude that it increases at a constant multiplicative rate of 1.5.

Answer:

(i) Total cost of the flat is Rs. 540000.

(ii) Expenditure incurred on labour is Rs. 150000

Step-by-step explanation:

According to the question, cement cost is Rs. 112500, which represents 75° in the pie chart.

(i) The total cost of the flat is represented by the total 360° in the pie chart.

∴ Using unitary method

75° represents Rs. 112500

⇒ 360° represents = [tex]\frac{112500}{75}[/tex]  ×  360

                                = Rs. 540000

∴  Total cost of flat = Rs. 540000

(ii) Similarly, to calculate the cost of labour, represented by 100° in the pie chart, we can use the unitary method:

75° represents Rs. 112500

⇒ 100° represents =  [tex]\frac{112500}{75}[/tex]  ×  100

                               = Rs. 150000

∴ Cost of labour = Rs. 150000

You purchase a dishwasher for $1249.99 plus 4% sales tax.
The appliance store offers an installment loan that allows you to pay for
the dishwasher by making 12 equal monthly payments of $124.58. What
is the cost of credit, in dollars, for this loan? Round your answer to the
nearest cent.

Answers

$195

Total with tax
$1249.99x0.04 = $1299.98

Total for monthly payment for 12 months
$124.58 x 12 = $1494.96

Subtract both totals
$1494.96 - $1299.98 = $194.98

Another way…

Total with tax $1299.98 \ 12 = $108.33

Subtract given monthly payment
$124.58 - $108.33 = $16.25

Multiply $16.25 x 12 = $195



$194.97 is the cost of the credit loan.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

The total cost of the dishwasher with sales tax can be found by multiplying the price by 1.04:

$1249.99 × 1.04 = $1299.99

The cost of credit is the total amount paid through the installment loan minus the cost of the dishwasher:

12 × $124.58 = $1494.96

$1494.96 - $1299.99 = $194.97

Therefore, the cost of credit for this loan is $194.97.
