The zeros or roots of the quadratic function f(x) = 6x² – 24x +1 were found with the help of the formula.

The given quadratic equation is:

[tex]6x^{2} -24x+1=0[/tex]

Any equation of the form [tex]ax^{2} +bx+c=0[/tex] where a≠0 is called a quadratic equation.

We know the solution of a quadratic equation [tex]ax^{2} +bx+c=0[/tex] is given by:

[tex]x=\frac{-b +\sqrt{b^{2}-4ac } }{2a}[/tex]

[tex]x=\frac{-b -\sqrt{b^{2}-4ac } }{2a}[/tex]

So, the solution of the quadratic equation [tex]6x^{2} -24x+1=0[/tex] will be:

[tex]x=\frac{-(-24) +\sqrt{(-24)^{2}-4(6)(1) } }{2*6}[/tex]

[tex]x=\frac{12+\sqrt{138} }{6}[/tex]

[tex]x=\frac{12-\sqrt{138} }{6}[/tex]

Thus, the zeros or roots of the quadratic function f(x) = 6x² – 24x +1 were found with the help of the formula.

An equation is formed of two equal expressions. The given equation 12x+1=3(4x+1)-2 has infinite numbers of solutions.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

To find the solution to the equation we need to solve the given equatiopn. Therefore, the equation can be written as,

[tex]12x+1=3(4x+1)-2\\12x+1=12x+3-2\\12x+1=12x+1[/tex]

As we can see that both sides of the equation are similar to each other, therefore, for any value of x the equation will be satisfied.

Thus, the given equation 12x+1=3(4x+1)-2 has infinite numbers of solutions.

Answer:

This looks like an acute triangle

Step-by-step explanation:

This looks like an actue triangle because all of the sides look  less than 90 degrees

Also you can use prossess of elemination:

It is not a right triangle because it does not have a 90 degree angle

it is not a obtude triangle because the angles do not look grather than 90 drgress

and this is not an equlateral triangle because the angles and not all the same.

So this leave acute triangle

If H is the circumcenter of triangle JKL then true statement is JH ≈ LH.

The circumcenter of a triangle is the point of intersection of the perpendicular bisectors of the triangle's sides. It is the center of the circumcircle, which is the circle passing through all three vertices of the triangle.

The circumcenter is equidistant from the three vertices of the triangle.

This means that the distance from the circumcenter to each vertex is the same.

i.e., the distance of point H is equal from J, K and L.

Then, the length of each of is equal which is

C: 8, 15, 17

Step-by-step explanation:

The easiest way to do this is simply to memorize the first few Pythagorean triples. It saves time. But it can also be hard to remember that. To see if something is a triple...

1. [tex]a^{2} + b^2=c^2[/tex]. This means square the first one, the second and add. Then square the last one. The sum of the first two with the last one should be the same.

2. For this to work, they have to be in order from least to greatest. All of these are.

3. Let's fill in the equation:

8^2= 64.

15^2= 225.

225+64= 289

17^2= 289.

It matches! It's a triple.

The sequence an=an−1+2 is an arithmetic sequence

The first three terms in the sequence are (a) 8, 10, 12

The sequence is given as:

an=an−1+2

Where:

a1 =8

Start by calculating a2 using:

a2=a1+2

This gives

a2=8+2 = 10

Calculate a3 using:

a3=a2+2

This gives

a3=10+2 = 12

So, we have:

a1 = 8, a2 = 10 and a3 = 12

Hence, the first three terms in the sequence are (a) 8, 10, 12

Answer:

No its 2/3 > 5/8

Step-by-step explanation:

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as:

2/3 = 0.667

5/8 = 0.625

Then, we compare the two decimal numbers to get the answer.

0.667 is greater than 0.625. So 2/3 > 5/8

Answer:

No, 2/3 is bigger than 5/8

Step-by-step explanation:

If you convert 2/3 into a deciamal it is 0.666

and if you convert 5/8 into a decimal it is 0.625

therefore 2/3 is the bigger fraction and the statement is not correct.

Hope this helps!!!!
