$(fg)(x)\text{ = }3x^3+4x^2+x$

Here, we want to find the product of the two given functions

Mathematically;

$\begin{gathered} (fg)(x)\text{ = f(x) }\times\text{ g(x)} \\ \\ =(3x+1)(x^2+x) \\ =3x^3+3x^2+x^2+x \\ =3x^3+4x^2+x \end{gathered}$

Circle assignment! THANKS so much its worth so much of my grade

Answer:

1. B) Figure B.

2. C) Figure C.

3. D) Figure D.

4. C) Figure C.

Step-by-step explanation:

Given: Radius of Circle A= 4

Radius of Circle B= 5

Radius of circle C= 6

Radius of circle D= 7

Now, finding circumference and area of all the circle.

We know, circumference of circle= $2\pi r$

Area of circle= $\pi r^{2}$

Where, r= radius of circle and π = 3.14

First, solving for figure A

Circumference= $2\times 3.14\times 4= 25.12\ cm$

Area= $3.14\times 4^{2} = 50.24\ cm^{2}$

Solving for Figure B

Circumference= $2\times 3.14\times 6= 31.4\ cm$

Area= $3.14\times 5^{2} = 78.5\ cm^{2}$

Solving for Figure C

Circumference= $2\times 3.14\times 6= 37.68\ cm$

Area= $3.14\times 6^{2} = 113.04\ cm^{2}$

Solving for Figure D

Circumference= $2\times 3.14\times 7= 43.96\ cm$

Area= $3.14\times 7^{2} = 153.86\ cm^{2}$

∴ 1. Answer is Figure B.

2. Answer is figure C.

3. Answer is Figure D

4. Answer is Figure C.

Help center of circle

Lelu [443]

Answer:

Center = (7, - 5)

Radius = 3

Step-by-step explanation:

${x}^{2} + {y}^{2} + 14x - 10y + 65 = 0 \\ {x}^{2} + 14x + {y}^{2} - 10 + 65 = 0 \\ ( {x}^{2} + 14x + {7}^{2}) - {7}^{2} + ({y}^{2} - 10y + {5}^{2}) \\- {5}^{2} + 65 = 0 \\ (x + 7)^{2} + (y - 5)^{2} - 49 - 25 + 65 = 0 \\ (x + 7)^{2} + (y - 5)^{2} - 49 + 40= 0 \\ (x + 7)^{2} + (y - 5)^{2} - 9= 0 \\ (x + 7)^{2} + (y - 5)^{2} = 9 \\ (x + 7)^{2} + (y - 5)^{2} = {3}^{2} \\ equating \: it \: with \: \\ (x - h)^{2} + (y - k)^{2} = {r}^{2} \\ - h = 7 \implies \: h = - 7 \\ - k = - 5 \implies \: k = 5 \\ center = ( - h, \: - k) = (7, \: \: - 5) \\ \\ radius \: r = 3$
