The quadratic function that passes through the point  (0,6), (3,15.8), and (9.5,0) is y = -0.6x² + 5.07x + 6

<h3>How to determine the quadratic function?</h3>

The points are given as:

(0,6), (3,15.8), and (9.5,0)

A quadratic function is represented as:

y = ax² + bx + c

Next, we substitute the points in the equation.

a(0)² + b(0) + c = 6

a(3)² + b(3) + c = 15.8

a(9.5)² + b(9.5) + c = 0

Simplify the expressions

c = 6

9a + 3b + c = 15.8

90.25a + 9.5b + c = 0

Solve for a, b and c using a graphing calculator

a = -0.6

b = 5.07

c = 6

Hence, the quadratic function is

y = -0.6x² + 5.07x + 6

Can somebody explain step by step ?
lukranit [14]

Answer:

3m\sqrt[5]{2m^4p^4}

Step-by-step explanation:

We want to find the fifth root of 486m^9p^4. In order to do so, we need to factorise

Let's factorise 486 first:

486 = 2 * 243 = 2 * 3^5

Ah, we see that 3^5 can be taken out and becomes 3 outside of the 5th root since the 5th root of

Now look at the variables. We see that since we have p^"4", whose exponent is less than 5, it's impossible for us to write it as a power of 5, so we leave this in the root.

We also have m^"9", which can be written as m^"5" * m^"4". Again, we see that the m^"4" term will have to remain inside the root, but we can take out the m^"5", which becomes m.

Our final answer is thus: 3m\sqrt[5]{2m^4p^4}.

I need help plz!!!!!!!
RSB [31]
You'll first need to calculate the measure of angle R.  From the diagram we see that 
              opp       33
tan R = ------- = ----- = 0.589, so, using the inv. tang. function, R = 0.589 rad.    
              adj        56
                        opp                                  33
Then sin R = --------- = sin 0.589 rad = ------------------------- = 0.508 rad
                         hyp                                sqrt(33^2 + 56^2)  

                                                                                        or  29.089 degrees

Using Factoring, solve the equation.<br><br> 2x^2 + 10x = (-8)
harkovskaia [24]
Hello there!

We first want to start by setting the equation equal to 0.

We do this by adding/subtracting the costant to the right of the equal sign to both sides, like this:

2x^2+10x(+8) = (-8)(+8)

We now have 2x^2+10x+8=0

Now we find the GCF, which is 2 in this case because 2 goes into 2, 10, and 8. Now divide all terms by 2.

Now we have x^2+5x+4=0

To further factor we now need to take the last term (4) and the middle term (5) and find out what multiplies to be 4 and adds to be 5. The answer to this is 4 and 1.

Now we are left with (x+4) and (x+1). We have no leading coefficient to divide the x by, so now we set each new equation equal to 0 and solve by getting x by itself. It will look like this:

x+4=0, x+4(-4)=-4

x+1=0, x+1(-1)=-1

After factoring, your answers will be x=-4 and x=-1.

Hope this helps!
