Answer:A is a quadratic function

Step-by-step explanation:

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. If you solve the function, y= 2x^2+x-6.

Can someone please help me with this ASAP!! (will mark as brainliest if correct)
sattari [20]

Answer:

P = 6x-2

x = 14

Step-by-step explanation:

To find the perimeter, we add the sides

P = 4x-8 + 3-2x + 5x+3

Combine like terms

P = 4x-3x+5x  -8+3+3

  = 6x -2

Now we know the perimeter

82 = 6x-2

Add 2 to each side

82+2 = 6x-2+2

84 = 6x

Divide each side by 6

84/6 = 6x/6

14=x

I need this math problem done as soon as possible!
Vesna [10]

Answer:

See below

Step-by-step explanation:

<u>Parent function:</u>

  • y = 3ˣ

<u>Transformed function:</u>

  • y = 4(3)⁻²ˣ⁺⁸ + 6, (note. I see this as 8, sorry if different but it doesn't make any change to transformation method)

<u>Transformations to be applied:</u>

  • f(x) → f(-x) reflection over y-axis
  • f(-x) → f(-2x) stretch horizontally by a factor of 2
  • f(-2x) → f(-2x + 8) translate 8 units right
  • f(-2x + 8) → 4f(-2x + 8)  stretch vertically by a factor of 4
  • 4f(-2x + 8) → 4f(-2x + 8) + 6 translate 6 units up

Find the with of a triangle as a 15 cm high in a hypogynous of a 19 cm​
Inessa05 [86]

Answer:

This other side of the triangle is equal to about 11.7 cm

Step-by-step explanation:

In order to find out the third side of the triangle we will just use the Pythagoras Theorem.

c^{2} =a^{2} + b^{2}

Since we know the hypotenuse and we know one of the legs, in order to find the second leg we just substitute the values and solve the equation and so we get...

c^{2} =a^{2} + b^{2}\\19^{2} = 15^{2} + b^{2}\\361 = 225 + b^{2} \\

b^{2} = 361 - 225\\b^{2} = 136\\b = \sqrt{136} \\

And so b ≈ 11.66190
