Equation D , y =2.3x²-2.4x+3.5 gives the Quadratic curve-of-best-fit for the data in the table.

<h3>What is a Quadratic Equation ?</h3>

A Quadratic equation is an equation that can be represented as

y = ax²+bx+c

Here in the question the data points and the quadratic equations are given ,

We have to find the best fit

From the graph attached the best fit can be determined.

Equation D , y =2.3x²-2.4x+3.5 gives the Quadratic curve-of-best-fit for the data in the table.

Is it possible to draw a triangle whose angles measure 50°, 50°, and 80°?
Firdavs [7]
First of all, we know a quality of all interior angles of a triangle, they should add to 180 degrees. 

Does 50+50+80 degrees give 180 degrees? 

100+80=180 degrees 

Therefore, yes, it is possible to draw a triangle with the angle measures given to be 50, 50 and 80 degrees. 

Hope I helped :)

I NEED HELP PLEASE, THANKS! :) Determine the zeros for and the end behavior of f(x) = x(x – 4)(x + 2)^4.
Amiraneli [1.4K]

Answer:  a) zeros: x = {0, 4, -2}

               b) as x → ∞,  y → ∞

                   as x → -∞,  y → ∞

<u>Step-by-step explanation:</u>

I think you mean (a) find the zeros and (b) describe the end behavior

(a) Find the zeros by setting each factor equal to zero and solving for x:

      x (x - 4) (x + 2)⁴ = 0

  • x = 0   Multiplicity of 1  --> odd multiplicity so it crosses the x-axis
  • x = 4  Multiplicity of 1  --> odd multiplicity so it crosses the x-axis
  • x = -2 <u>Multiplicity of 4 </u> --> even multiplicity so it touches the x-axis

                       Degree  =  6

(b) End behavior is determined by the following two criteria:

  1. Sign of Leading Coefficient (Right side): Positive is ↑, Negative is ↓
  2. Degree (Left side): Even is same direction as right side, Odd is opposite direction of right side

Sign of the leading coefficient is Positive so right side goes UP

                                                                        as x → ∞,  y → ∞

Degree of 6 is Even so Left side is the same direction as right (UP)

                                                                        as x → -∞,  y → ∞

Find the value of x
Svet_ta [14]

Answer:

150^o

Step-by-step explanation:

<u>Step 1:  Distribute the plus</u>

<u />(x + 15)^o + (135 - x)^o

x + 15 + 135 - x

<u>Step 2:  Combine like terms</u>

<u />x + 15 + 135 - x

(x - x)^o + (15 + 135)^o

0 + 150^o

150^o

Answer:  150^o

A car traveled at an average rate of 51 miles per hour on one highway. It then traveled at an average rate of 71 miles per hour
sergiy2304 [10]

d1 = 51(t)

d2 = 71(8 - t)

d1 + d2 = 508

and now you just have to solve for t.
