Answer:

17pi/15

Step-by-step explanation:

s = r *theta where r is the radius and theta is the central angle in radians

Convert 51 to radians

51 * pi/180 = 51pi/180

s = 4 * 51pi/180

= 17pi/15

Answer:

$Arc\ length = 3.6 cm$

Step-by-step explanation:

$Arc \ Length = 2 \pi r \frac{ \theta}{360}$

$= 2 \times \pi \times 4 \times \frac{51 }{360}\\\\=2 \times \pi \times \ 4 \times 0.142\\\\=3.5688 \\\\Arc\ length = 3.6 cm$

Answer:

see explanation

Step-by-step explanation:

(f + g)(x) = f(x) + g(x), so

f(x) + g(x)

= x² + 5x + 6 + x + 3 ← collect like terms

= x² + 6x + 9

-------------------------------------------------

(f - g)(x) = (f(x) - g(x), so

f(x) - g(x)

= x² + 5x + 6 - (x + 3) ← distribute by - 1

= x² + 5x + 6 - x - 3 ← collect like terms

= x² + 4x + 3

---------------------------------------------------

(f • g)(x)

= f(x) × g(x)

= (x² + 5x + 6)(x + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x²(x + 3) + 5x(x + 3) + 6(x + 3) ← distribute parenthesis

= x³ + 3x² + 5x² + 15x + 6x + 18 ← collect like terms

= x³ + 8x² + 21x + 18

---------------------------------------------------------------

( $\frac{f}{g}$ )(x)

= $\frac{f(x)}{g(x)}$

= $\frac{x^2+5x+6}{x+3}$ ← factor the numerator

= $\frac{(x+2)(x+3)}{x+3}$ ← cancel common factor (x + 3) on numerator/ denominator

= x + 2

Y intercepts of 3x^2-12x+6

Inessa05 [86]

Y=3x^2. -12x+6

If x= 0 then y= 3•0^2 -12•0+6=6
X=0, y=6

y intercept is the place where the curve touches the y-axis and is at point (0, 6)

Suppose that a line segment is translated. Which of the following is true?

nevsk [136]

Answer:

The line segment's position changes, but its length remains the same.

Step-by-step explanation:

When a line segment is translated, it only will move its position up, down, or to the side.

The slope and length will stay the same, but the position will change.

So, this answer is correct because the position changes but not the length.
