What is the discriminant of the quadratic equation 4x^2-7x-6=04x 2 −7x−6=0?

Wittaler [7]

Answer:

145

Step-by-step explanation:

The discriminant of quadratic ...

ax^2 +bx +c = 0

is ...

d = b^2 -4ac

For your quadratic, you have a=4, b=-7, c=-6, so the discriminant is ...

d = (-7)^2 -4(4)(-6) = 49 +96 = 145

The discriminant is 145.

a rectangular wall with a length of 10x and width of 20 x has a rectangular doorway with a length of 5x and a width of 2x. What

Shtirlitz [24]

Answer:

∴ The the surface area of the wall is $190x^{2} \ square\ unit$ .

Step-by-step explanation:

Given that,

The length of rectangular wall is $10x$ .

The width of rectangular wall is $20x.$

The length of doorway is $5x.$

The width of doorway is $2x.$

and, we have to find the surface area of rectangular wall.

Now,

The length of rectangular wall is $10x$ .

The width of rectangular wall is $20x.$

∴ Total surface area of a rectangular wall $= Length\ of\ wall\times Width\ of\ wall$

$= 10x\times 20x$

$=$ $200x^{2} \ square\ unit$

Total surface area of a rectangular wall is $200x^{2} \ square\ unit$ .

Again, The length of doorway is $5x.$

The width of doorway is $2x.$

∴Total surface area of doorway $=Lenght\ of\ doorway\times Width\ of\ doorway$

$=5x\times 2x$

$=10x^{2} \ square\ unit$

Total surface area of doorway is $10x^{2} \ square\ unit$ .

∴The remaining surface area of a rectangular wall is $=$ $200x^{2} -10x^{2}$

$=190x^{2} \ square\ unit$

∴ The the surface area of the wall is $190x^{2} \ square\ unit$ .

Someone help pleaseee

Doss [256]

Answer:

38°

Step-by-step explanation:

All triangles have a sum of 180°

180 - (119 + 23) = missing angle

180 - (142) = missing angle

38 = missing angle

So, the missing angle has a measurement of 38°

A sphere rolls up an inclined plane of inclination angle 30 degree. At the bottom of the incline the center of mass of the spher

Zigmanuir [339]

Answer: The sphere is 0.002548 cm travel up the plane.

Step-by-step explanation:

Since we have given that

Inclination angle = 30°

Translational speed = 0.25 m/s

As we know that

$KE=0.5\times lw^2=PE$

and

Length of solid sphere is given by

$l=\dfrac{2Mr^2}{5}$

So, it becomes,

$KE=0.5\times \dfrac{2Mr^2}{5}w^2=Mgd\sin \theta$

And $0.25\ m/sv=rw$

So, it becomes,

$1\times (0.25)^2=5\times d\times 9.81\times \sin 30^\circ\\\\0.0625=49.05d\times \dfrac{1}{2}\\\\\dfrac{0.125}{49.05}=d\\\\d=0.002548$

Hence, the sphere is 0.002548 cm travel up the plane.

Last season there were 26 students on the Springfield High

aivan3 [116]

Answer:

Step-by-step explanation:

What percent of the team are seniors?

= 18/26 *100 = 69.23%

How many players are juniors?

= 19/100 * 26 = 5 Players

Freshman and sophomores together make up what percent of the team?

= (26-(18+5))/26 *100 = 3/26 *100 = 11.54%
