Answer:

D) (1,-2)

Step-by-step explanation:

The vertex for a quadratic function is either the minimum point or the maximum point of the curve depending on the nature of the curve from which the curve changes direction.

In the graph shown for the quadratic function, it has minimum point as the graph opens upwards. So, the vertex is the minimum point of the curve.

The vertex of the graph is $(1,-2)$ .

I think of a number, double it and add eleven. I get twenty five. Using the statement above form an equation using the letter x!

Wittaler [7]

Answer:

2x + 11 = 25

x = 7

Step-by-step explanation:

Let the number be x.

Double of x and add 11 equals 25.

2x + 11 = 25

Solve the equation.

2x + 11 = 25

Subtract 11 on both sides.

2x = 25 - 11

2x = 14

Divide 2 on both sides.

x = 14/2

x = 7

|x-5|=3 Whats x? please help?

finlep [7]

Answer:

x = 8 or x = 2

Step-by-step explanation:

We know x - 5 = 3 or x - 5 = -3.

Possibility 1:

Step 1: Add 5 to both sides.

$x-5+5=3+5$
$x=8$

Possibility 2:

Step 1: Add 5 to both sides.

$x-5+5=-3+5$
$x=2$

Step 2: Check if both solutions apply to original equation.

$|8-5|=3$
$|3|=3$
$3=3$
$|2-5|=3$
$|-3|=3$
$3=3$

Michael estimated his mass as 8 kilograms. Is his estimate reasonable? Justify your answer.

Gennadij [26K]

Answer: The answer is Yes.

Step-by-step explanation: Given that Michael estimated his mass and found it to be 8 kilograms. It may sound awkward to us, but its true. Because when we measure our weight by the weight machine it gives us the product of our actual mass and the acceleration due to gravity.

From second law of motion, we have

Weight = mass × acceleration due to gravity.

That is, W = m × 9.8 m/sec².

The unit of mass is kilogram and 1 kg m/sec² = 1 Newton. Therefore, the unit of the weight we generally measure is Newton (N), not kilogram. Here is what we make mistake usually.

Thus, if Michael' mass is 8 kg, then his weight will be

W = 8 × 9.8 kg m/sec² = 78.4 N, which is normal weight of a person.

Thus, his estimation is perfectly OK.
