Answer:

Arc Length : 43.98

Sector Area : 175.92

Step-by-step explanation:

Formula for Arc Length : 2·π·r·Ф / 360

Formula for Sector Area : π· $r^{2}$ ·Ф / 360

- Where r is the radius

- Where Ф is the angle

Arc Length : 2 · π · 8 · 315 / 360 = 43.98

Sector Area : π · $8^{2}$ · 315 / 360 = 175.92

hope this helps !! :D

If 2x + 5y = -5 what is x if y = -5 HELP ASAP

mash [69]

Answer:

x=10

Step-by-step explanation:

first substitute y with the value (-5)

2x+5(-5)=-5 which is simplified to 2x+-25=-5

add 25 to -5 which gives you 2x=20

then divide 20 by 2 which makes x=10

One factor of the polynomial 6x3 − x2 + 8x + 5 is (2x + 1). What is the other factor of the polynomial? (Note: Use long division

maria [59]

Answer:

(3x^2 - 2x + 5)

Step-by-step explanation:

3x^2 - 2x + 5

$2x + 1 \sqrt{6 {x}^{3} - {x}^{2} + 8x + 5 }$

- (6x^3 + 3x^2)

-4x^2 +8x +5

- (-4x^2 - 2x)

10x + 5

-(10x + 5)

(2x+1) (3x^2 - 2x + 5) = 6x^3 - x^2 + 8x + 5

Therefore the other factor of the polynomial is (3x^2 - 2x + 5)

F(x) = 4x^2+2x+6 what is the discriminant of f? How many distinct real number zeros does f have?

Sunny_sXe [5.5K]

Answer:

The discriminant of f is 92, and it has no real zeros

Step-by-step explanation:

The discriminant of a quadratic is $b^2-4ac$ , where the quadratic is in the form $ax^2+bx+c$ . The discriminant of this one is therefore:

$2^2-4(4)(6)=4-96=-92$

Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!
