Answer:

Calculation of the discriminant of the polynomial : 3⋅x2−6+2⋅x

Applying the formula to calculate the discriminant Δ=b2−4⋅a⋅c with : a=3, b=2,c=-6

Δ=(2)2−4⋅(3)⋅(−6)=4+72=76

The discriminant of the polynomial 3⋅x2−6+2⋅x is equal to 76

Solve the equation for y<br> Y minus 5 equals 1/3 (x plus 12)
Vinvika [58]

Answer:

ok so this problem you are basically just rearranging it. you're going to want y by itself.

Step-by-step explanation:

let's start with the original equation: 5-y=1/3x +12

so first you have to move the five over, so you subtract 5 from both sides. -y=1/3x+12-5

then you subtract the 5 from the twelve since they're like terms: -y=1/3x+7

and finally you have to move the negative over. when you move the negative think of it like dividing negative one from both sides, everything on the other side has to get the negative.

so we're left with y=-1/3x-7

I hope this helps!

A ladder is leaning against the side of a building and positioned such that the base of the ladder is 17 ft from the base of the
andrezito [222]

Answer:

The ladder is 28.6 feet long.

Step-by-step explanation:

Given that:

Length of base = 17 feet

Length above the ground = 23 feet

These forms two legs of right angled triangle.

The length of ladder will be the hypotenuse.

Using Pythagorean theorem;

a^2+b^2=c^2\\(17)^2 + (23)^2 = c^2 \\289 + 529 = c^2 \\c^2 = 818

Taking square root on both sides

\sqrt{c^2}=\sqrt{818}\\c=28.6

Hence,

The ladder is 28.6 feet long.
