Identify the center and the radius of each circle.

C. X^2+2x+1+y^2+4y+4=9

Answers

Answer 1

Answer:

[tex]Center =(-1,\: -2),\: radius = 3\: units[/tex]

Step-by-step explanation:

[tex] x^2 +2x + +1 + y^2++4y+4=9[/tex] (Given equation of circle)

[tex]\implies (x^2 +2x + +1) + (y^2++4y+4)=(3)^2[/tex]

[tex]\implies (x+1)^2 + (y+2)^2=(3)^2[/tex]

Comparing the above equation with standard form of circle i.e. [tex](x-h)^2+(y-k)^2=r^2[/tex], we find:

[tex]h=-1, \: k = -2,\: r = 3[/tex]

[tex]Center =(h, \: k )=(-1,\: -2),\: radius = 3[/tex]

Show that (x − 9)(x − 1) ≡ x^2 − 10x + 9

Answers

        We will expand the factored form of (x − 9)(x − 1) into the same form as x² − 10x + 9 to show they are equal.

Distribute and multipy out:

(x − 9)(x − 1)

x * x = x²

x * -1 = -x

x * -9 = -9x

-9 * -1 = 9

Add together:

x² +  -x + -9x + 9

x² − 10x + 9

Use the Reflexive property:

x² − 10x + 9 = x² − 10x + 9 ✓

complete the statement, and find the value of x in the diagram.

Answers

The completely factored expression of 12x⁴ + 39x³ + 9x² is 3x²(4x + 1)(x + 3)

How to factor the expression?

The polynomial expression is given as;

12x⁴ + 39x³ + 9x²

Factor out 3x² from the expression

3x²(4x² + 13x + 3)

Expand

3x²(4x² + 12x + x + 3)

Factorize the expression

3x² * 4x(x + 3) + 1(x + 3)

Factor out x + 3

3x²(4x + 1)(x + 3)

Hence, the completely factored expression of 12x⁴ + 39x³ + 9x² is 3x²(4x + 1)(x + 3)

The value of David's investment will be at least $415 after a period of years. Hint: Use the formula A = P(1 + r)t, where A is the amount after t years, P is the amount invested, r is the rate of interest, and t is the time period. Use a calculator to compute the answer, and round it off to the nearest year.

Answers

The value of David's investment will be at least $415 after a period of 20 years

Compound interest

The formula for calculating the compound interest is expressed as:

A = p(1+r)^t

Given the following parameters

A = $415P = $230r = 3% = 0.03

Substitute

415 = 230(1+0.03)^t
415/230 = 1.03^t
1.8043 = 1.03^t
t = ln(1.8043)/ln1.03

t = 20 years

The value of David's investment will be at least $415 after a period of 20 years
