If the sum of the roots of the equation 3x² + kx + 1 = 0 is 7. then what the value of k

koban [17]

Answer:

The value of k is -21

Step-by-step explanation:

ax² + bx + c = 0

Sum of the roots = -b/a

3x² + kx + 1 = 0

= sum of the roots = -k/3

-k/3 = 7

Now, Multiply both side by (-3) we get,

(-3)-k/3 = 7(-3)

k = -21

Thus, The value of k is -21

A pizza slice is in the shape of a circular sector OAB, with the central angle 0 = 50 deg and a radius of 7cm. 0 A B В Find the

Goryan [66]

Answer:

The perimeter of the pizza slice is 20.1 cm

Step-by-step explanation:

Perimeter of a Sector of a Circle

The arc length of a sector of a circle of radius r and angle θ is given by:

L = rθ

The angle must be expressed in radians.

The total perimeter of the circular sector, including the two radii, is:

P = rθ + 2r

The pizza slice has a radius of r=7 cm and a central angle of θ=50°

Converting to radians:

$\theta=50*\frac{\pi}{180}=\frac{5\pi}{18}$

The perimeter is:

$P = 7*\frac{5\pi}{18} + 2*7$

Calculating:

P = 20.1 cm

The perimeter of the pizza slice is 20.1 cm
