What’s the answer to this equation?

Tresset [83]

Answer:

Part A) The graph in the attached figure

Part B) see the explanation

Step-by-step explanation:

Part A) Graph the function

we have the quadratic function

$y=3x^2-12x-36$

This is a vertical parabola open upward

The vertex is a minimum

using a graphing tool

The graph in the attached figure

Part B) What are the values of a, b and c?

we know that

The values of a and b represent the x-intercepts of the quadratic equation

The x-intercepts are

(-2,0) and (6,0)

so

$a=-2\\b=6$

Find the value of c

we know that

The x-coordinate of the vertex in a vertical parabola is equal to the midpoint of the roots

so

The value of c is equal to

$c=\frac{a+b}{2}$

substitute the given values

$c=\frac{-2+6}{2}=2$

see the attached figure

Convert the following measurements

Sphinxa [80]

Answer:

1. 32 inches = 81.28 centimeters

2.402 000 millimeters = 402 meters

3. 2.85 meters = 285 centimeters

4.2 kilometers= 2000000 millimeters

5. 71 meters = 0.071 kilometers

6. 8kg = 8000 g

7. 3000 g = 3 kg

8. 2.5 kg = 2500 g

9 850 mg = 9.85 g

10.75 dg = 1075 m
