Answer:

4. x ≥ -1

Step-by-step explanation:

The graph shows a directed line that starts at -1 towards the your right. The full circle indicates that -1 is included among the possible values of x. This means that all possible values of x include -1 and above.

Therefore, we can say x is greater than or equal to -1.

This is represented as:

x ≥ -1

Answer:

Step-by-step explanation:

sqrt(x + 2) - 15 = -3

sqrt(x + 2) = 12 (add 15 to both sides)

x + 2 = 12² = 144 (square both sides)

x = 142.

Answer:

x = 142

Step-by-step explanation:

√x+2 - 15 = -3 (Given)

√x+2 = 12 (Add 15 on both sides)

x + 2 = 144 (Square both sides to get rid of the radical)

x = 142 (Subtract 2 on both sides)

Step-by-step explanation:

...

The slope of the line segment representing the flight is 0.04.

The slope of a line segment is calculated by dividing the change in the vertical direction (the altitude) by the change in the horizontal direction (the distance traveled). In this case, the change in the vertical direction is 800 meters (800 / 1000 = 0.8 kilometers) and the change in the horizontal direction is 20 kilometers. Therefore, the slope of the line segment is 0.8 / 20 = 0.04.

In other words, for every kilometer that Ron travels, he gains 4 meters in altitude.

Here is the solution in more detail:

Define the variables.

x: The distance traveled in kilometers.

y: The altitude in meters.

Write the equation for the line segment.

The slope of the line segment is 0.04, so the equation for the line segment is y = 0.04x + b.

We know that when x = 0, y = 0, so b = 0.

Substitute the known values into the equation.

We know that x = 20 and y = 800, so we can substitute these values into the equation to get 800 = 0.04 * 20 + 0.

Simplifying the right side of the equation, we get 800 = 0.8.

Solve for the slope.

The slope is 0.8 / 20 = 0.04.

Therefore, the slope of the line segment representing the flight is 0.04.

Answer:

179

Step-by-step explanation:

5x^2 + x - 7

5(6)^2 + 6 - 7

5(36) + 6 - 7

180 +6 -7

180 - 1

179

Answer:

179 is the correct answer.

Step-by-step explanation:

x = 6

5x^2 + x - 7

Now, replace both x's with 6 and solve,

5(6)^2 + 6 - 7

(6 x 6 = 36)

5 x 36 + 6 - 7

(5 x 36 = 180)

180 + 6 - 7 = 179

Given:

The side of square = 12 in.

Scale factor of enlargement = 3 in : 2 m

To find:

The proportion that is use to solve the side length, x, of the enlarged square.

Solution:

Let, the side of length of enlarged square = x m

In case of enlargement the corresponding sides are proportional.

[tex]\dfrac{3}{12}=\dfrac{2}{x}[/tex]

[tex]3x=2\times 12[/tex]

[tex]3x=24[/tex]

Divide both sides by 3.

[tex]x=\dfrac{24}{3}[/tex]

[tex]x=8[/tex]

Therefore, the required proportion is [tex]\dfrac{3}{12}=\dfrac{2}{x}[/tex] and the side length of the square after enlargement is 8 m.

The value of A from the given equation is A=B³/(D-2q).

The given equation is DA-2qA=B³.

We need to solve the given equation for A.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, DA-2qA=B³ can be solved for A as follows:

A(D-2q)=B³

⇒A=B³/(D-2q)

Therefore, the value of A from the given equation is A=B³/(D-2q).

One solution ; (2,5)

Step-by-step explanation:

When looking at a graph, the number of times the lines intersect is equal to how many solutions there are.

In this instance, there is only one intersection. Therefore, there is only one solution.

The solution is also that point of intersection. Therefore, the solution here is the point (2,5).

Answer:

P(X ≥ 2) = 0.5967

Step-by-step explanation:

Using binomial probability distribution formula;

P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)

two percent of a product are defective. Thus; p = 0.02

a lot of 100 items are ordered. Thus, n = 100

Probability that there are no defective items is;

P(X = 0) = C(100, 0) × 0.02^(0) × (1 - 0.02)^(100 - 0)

P(X = 0) = 0.98^(100) = 0.1326

the probability that there are at least two defective items will be;

P(X ≥ 2) = 1 - P(X < 2)

Now,

P(X < 2) = P(X = 0) + P(X = 1)

P(X = 1) = C(100, 1) × 0.02^(1) × (1 - 0.02)^(100 - 1)

P(X = 1) = 100 × 0.02 × 0.98^(99) = 0.2707

Thus;

P(X < 2) = 0.1326 + 0.2707

P(X < 2) = 0.4033

P(X ≥ 2) = 1 - 0.4033

P(X ≥ 2) = 0.5967
