For what values of m are there 2 different distinct real solutions? Give your answer as an inequality. X^2-2x+m.

I'm not sure, but I think the formula is b^2-4ac>0​

Answers

Answer 1

Answer:

m<1

Step-by-step explanation:

If the expression is in the form of [tex]ax^2+bx+c[/tex], then the condition for having 2 different real roots is

[tex]b^2-4ac>0\cdots(i)[/tex].

The given expression is [tex]x^2-2x+m[/tex].

Here, a=1, b=-2 and c=m.

So, by using equation (i),

[tex](-2)^2-4(1)(m)>0[/tex]

[tex]\Rightarrow 4-4m>0[/tex]

[tex]\Rightarrow 4m<4[/tex]

[tex]\Rightarrow m<4/4[/tex]

[tex]\Rightarrow m<1[/tex].

Hence, the condition for the expression [tex]x^2-2x+m[/tex] to have two different real roots is m<1.

Tony bought 255 1-inch nails and 5 boxes of 2-inch nails. Each box of 2-inch nails had equal amounts of nails in them. He bought a total of 620 nails. Find the number of nails in each box of 2-inch nails.

Answers

Answer:

73 nails

Step-by-step explanation:

Number of 1 inch = 255

Boxes of 2 - inch = 5

Each box of 2 _inch has equal amount of nails

Total number of nails = 620

Number of nails in each box of 2_inch nails:

Let Number of nails in each box = b

Number of 1_inch + 5 * number of 2_inch = 620

255 + 5b = 620

5b = 620 - 255

5b = 365

5b / 5 = 365 / 5

b = 73

Hence, there are 73 nails in each box of 2_inch nails

x + 2x + 12y + 4 I don't know the answer can someone help me please

Answers

Answer:

The asnwer is 3x + 12y + 4

Answer:

I think you wrote it wrong but if not here

Step-by-step explanation:

Simplifying

2x + -12y = 4

Solving

2x + -12y = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12y' to each side of the equation.

2x + -12y + 12y = 4 + 12y

Combine like terms: -12y + 12y = 0

2x + 0 = 4 + 12y

2x = 4 + 12y

Divide each side by '2'.

x = 2 + 6y

Simplifying

x = 2 + 6y

~ The car makes a complete revolution in 8 s.
~ The radius of the Ferris wheel is 26 m.

~ The maximum height of the Ferris wheel above ground is 40 m.

"What is the maximum height of the Ferris wheel? "

Step-by-step explanation:

ive looked for the question nd couldnt find it so i sarcificed my grade for yall, welcome

The values of the Ferris wheel.

The Ferris wheel is a ride that is fired by the upright rotating wheel and is able of carrying multiple passengers. The table shows us the value of the height of a car of the Ferris wheel and as it travels in a circular motion. The time and height of the second and meters are given.

Thus the answer is if the car is loaded at 0 s, then people are at the lowest part.

The wheel data shows that in 2 seconds the height of the wheel is about 26 meters and in 16 seconds the height of the wheel is about 6 meters. Thus the car is located at 0s and people are at the lowest height of the wheel.Hence the option C is correct.
