Consider the circle in the diagram above. Point C is the center. DG = 14 cm 1. Name all the line segments which are radii (plural of radius). (page 353) 2. Name all the line segments which are diameters. (page 354) 3. How long is the radius? 4. How long is the diameter? 5. Find the circumference. (page 357) 6. Find the area. (page 363)

Answers

Answer 1

Answer: I saw the diagram.

1) radii: CD, CG, CF, CE, CH
2) diameter: DG, EF
3) radius: 14cm/2 = 7cm
4) diameter: 14cm because DG is the diameter, its measure is the measure of the diameter.
5) Circumference = 2 π r = 2 * 3.14 * 7cm = 43.96cm
6) Area = π r² = 3.14 * (7cm)² = 3.14 * 49cm² = 153.86 cm²

Which of the segments below is a secant?

Answers

Answer:

d. $\overline{BC}$

Step-by-step explanation :

We are given that a circle of center O.

We have to find the segment that is secant.

Secant : If a line which intersect the circle at two points.Then the line segment is called secant.

a. $\overline{OA}$

It is false because segment OA intersect the circle at one point A only.

b. $\overline{CD}$

It is false because segment CD intersect the circle at point D only.

c. $\overline{BC}$

It is true because it intersect the circle at two points .

d. $\overline{AB}$

It is false because it intersect the circle at one point A only.

Answer:c. $\overline{BC}$

Answer:

Step-by-step explanation:

A secant is a line which intersects the circle at 2 points

In the given diagram this is BC

Answers

Answer:

(1) A

(2) C

(3) B

(4) The coefficients are 4,3,-3.

(5) A

(6) D

(7) C

(8) B

Step-by-step explanation:

(1)

The given expression is

$(4x^2 + 15x - 3) - (-3x^2 + 5)$

Using distributive property.

$(4x^2 + 15x - 3) - (-3x^2) -( 5)$

$4x^2 + 15x - 3 + 3x^2 - 5$

On combining like terms.

$(4x^2+3x^2) + 15x +(- 3 - 5)$

$7x^2 + 15x-8$

Therefore, the correct option is A.

(2)

The given expression is

$-3f^2 + 4f - 3 + 8f^2 + 7f + 1$

On combining like terms.

$(-3f^2+ 8f^2) +( 4f + 7f )+(- 3 + 1)$

$5f^2 +11f -2$

Therefore, the correct option is C.

(3)

The given expression is

$(2x^2 + 6x + 1) + (-7x^2 + 2x - 3)$

Combined like terms.

$(2x^2-7x^2) + (6x+ 2x) + (1 - 3)$

$-5x^2 + 8x -2$

Therefore, the correct option is B.

(4)

The given expression is

$4x^2 + 3x - 3$

A number before variable terms are called coefficient of that term.

Therefore, the coefficients are 4,3,-3.

(5)

The given expression is

$6x^4 + 3x^3 - 2x^2 + 15x - 14$

It this polynomial, the number of terms is 5.

Therefore the correct option is A.

(6)

The given expression is

$-7x - 5x^2 + 5$

The coefficient to x is -7.

Therefore, the correct option is D.

(7)

The given expression is

$(2.5\cdot 10^4)(4\cdot 10^3)$

$(2.5\cdot 4)\cdot (10^4\cdot 10^3)$

Using product property of exponent.

$(10)\cdot 10^(4+3)$

$1\cdot 10^(1+4+3)$

$1\cdot 10^(8)$

Therefore, the correct option is C.

(8)

The given expression is

$2^2\cdot 2^8$

Using product property of exponent.

$2^(2+8)$

$2^(10)$

Therefore, the correct option is B.

$1.\n(4x^2+15x-3)-(-3x^2+5)\n=4x^2+15x-3+3x^2-5\n=7x^2+15x-8\leftarrow A.$

$2.\n-3f^2+4f-3+8f^2+7f+1\n=5f^2+11f-2\leftarrow C.$

$3.\n(2x^2+6x+1)+(-7x^2+2x-3)\n=2x^2+6x+1-7x^2+2x-3\n=-5x^2+8x-2\leftarrow B.$

$4.\n4x^2+3x-3\n\{4;\ 3;-3\}$

$5.\n6x^4+3x^3-2x^2+15x-14\n\{6;\ 3;-2;\ 15;-14\}\to5\leftarrow A.$

$6.\n-7x-5x^2+5\n\{-7\}\leftarrow D.$

$7.\n(2.5\cdot10^4)(4\cdot10^3)=2.5\cdot4\cdot10^(4+3)=10\cdot10^7\n=10^(1+7)=10^8=1\cdot10^8\leftarrow C.$

$8.\n2^2\cdot2^8=2^(2+8)=2^(10)\leftarrow B.$

What is the answer to 1/3 × 4/9

Answers

1/3 x 4/9 = 4/27 because you are just doing numerator x numerator and denominator x denominator.

Hey There!

Just like multiplication multiply, but when you multiply fractions you multiply the numerator and the denominator.

$(1)/(3)$ * $(4)/(9)$ = 4/27

First multiply the numerator 1*4=4, than multiply the denominator 3*9=27.

So, the final answer is $(4)/(27)$ .
