Y=3x²+3x+1,find the value of the discrimination​

Mathematics
1 answer:
Rufina [12.5K]3 years ago
5 0

Answer:

Step-by-step explanation:

a = 3

b = 3

c  = 1

Discriminate = sqrt(b^2 - 4ac)

Discriminate = sqrt(9 - 4*3*1)

Discriminate = sqrt(9 - 12)

Discriminate = sqrt(-3)

What negative value means that there are no real roots and the y intercept = 1. You should always graph this kind of question, which I am doing for you. I use Desmos which is a very handy program.

You should notice that the minimum is above the x axis. That means there are no real roots, just as the discriminate tells you.

Answer:

The shadow is 3 ft tall

Step-by-step explanation:

The older giraffe is 16 ft tall and 8 is half of 16 and 8ft is the length of the shadow so that means that half of the small girafe would be 3ft because half of 6 is 3.

Plz answer mhanifa!
wel

Answer:

I'm not mhanifa, but I am also really good at math (i'm in accelerated math rn) so I will try to help too.

Step-by-step explanation:

My tips:

1. Try to focus on formula's not small things like answers or definitions (they are still important but be more focused on formulas), this will really help you when you need to solve eqautions.

2. Don't over-study. Basically don't overload yourself with information, focus on the major things, if you overload yourself, you may not remember everything, and that would not be very helpful at all.

3. Don't try to study the things you are good at, study the things you struggle with, this will help you ALOT.

4. Take your time, you don't want to mess up because you are rushing, and you know math is really annoying and you can get the answer wrong for one incorrect calculation.

5. Get your sleep, this is very important

I hope this helps!! good luck on your EOG!!!!!!

1 = 73 - 2*0.5 = 72 cm

w = 60 - 2*0.5 = 59 cm

h = 38 - 1*0.5 = 37.5 cm

V = l × w × h

V = 72*59*37.5

V = 159,300 cm^3

Which of the following functions are continuous. Select all that apply.
Temka [501]
>>1st one- at X=0 Y=DNE so the function is not continious.
>>2nd one- there is Y value for every X so the function is continious.
>>3rd one- there is Y value for every X so the function is continious.
>>4th one- f(-1)=1 does not equal the limit of f(x).


because the limit as X aprroaches from the left and from ther right is different.
