Write an inequality for the shaded region shown in the figure.

Snezhnost [94]

Answer:

y ≥ x^2 - 1

Step-by-step explanation:

First, we can see that the shaded region is above what seems to be a parabola, and we also can see that the lines of the parabola are solid lines (which means that the points on the curve itself are solutions, so the symbol ≥ is used)

Then:

y ≥ a*x^2 + b*x + c

where a*x^2 + b*x + c is the general quadratic equation.

Now let's find the equation for the parabola:

f(x) = a*x^2 + b*x + c

We also can see that the vertex of the parabola is at the point (0, -1)

This means that:

f(0) = -1 = a*0^2 + b*0 + c

= -1 = c

then we have that c = -1

Then:

f(x) = a*x^2 + b*x - 1

Now we can look at the graph again, to see that the zeros of the parabola are at +1 and -1

Which means that:

f(1) = 0 = a*1^2 + b*1 - 1 = a + b - 1

f(-1) = 0 = a*(-1)^2 + b*(-1) - 1 = a - b - 1

Then we got two equations:

a + b - 1 = 0

a - b - 1 = 0

from this we can conclude that b must be zero.

Then:

b = 0

and these equations become:

a - 1 = 0

solving for a, we get:

a = 1

Then the quadratic equation is:

f(x) = 1*x^2 + 0*x - 1

f(x) = x^2 - 1

And the inequality is:

y ≥ x^2 - 1

There are 5 questions listed below. Each question includes:

Tom [10]

a. 22. 79 - amount

b. 129 - amount

c. 358. 3 - base

d. 40. 65% - percent

e. 2. 58% - percent

<h3>How to determine the values</h3>

It is important to note that a percentage is the number or ratio expressed as a fraction of 100.

It is denoted using the percent sign, "%"

a. What number is 53% of 43

= 53/ 100 × 43

= 0. 53 × 43

= 22. 79

b. 43% of 300

= 43/ 100 × 300

= 129

c. 12% of what number is 43

12/ 100 × x = 43

x = 43 × 100/ 12

x = 358. 3

d. 43 is what percent of 106

43/106 × 100/ 1

4300×/ 106

40. 5%

e. What percent of 43 is 6

43/ 100 × 6

2.58%

Thus, the percentage of a value is that value divided by 100

The number of marriage licenses issued by Clark County Nevada, the county where Las Vegas is located, has been

REY [17]

The number of marriage licenses were issued in 2003 is 21586.

According to the statement

we have to find the number of marriage licenses were issued in 2003

and the given equation is y=3.405x^2-17674x+21533000

And in this equation x represent the time

And Y represent the number of marriage certificate issued.

So, in given equation

y=3.405x^2-17674x+21533000

we fill the value of X and find the value of Y means tne number of marriage license is issued in 2003

We know that X = 3 from 2000 to 2003

Then put X=3 in the given equation.

Then

This is the equation (1) represent the change

y=3.405(3)^2-17674(3)+21533000 -(1)

y = 30.645+53022+21533000

y = 21586052.645

On nearest hundred the value becomes 21586.

So, The number of marriage licenses were issued in 2003 is 21586.
