The solution to the inequality [tex]$2|v-7|-4 \geq 42$[/tex] in interval notation is given by [tex]$-16 \leq v \leq 30$[/tex].

Step-by-step explanation:

An absolute value inequality [tex]$2|v-7|-4 \geq 42$[/tex] is given.

It is required to solve the inequality and write the solution in interval form.

To write the solution, first solve the given absolute value inequality algebraically and then write it in interval notation.

Step 1 of 4

The given absolute value inequality is [tex]$2|v-7|-4 \geq 42$[/tex].

Add on both 4 sides,

[tex]$$\begin{aligned}&2|v-7|-4 \geq 42 \\&2|v-7|-4+4 \geq 42+4 \\&2|v-7| \geq 46\end{aligned}$$[/tex]

Step 2 of 4

Divide by 2 on both sides,

[tex]$$\begin{aligned}&\frac{2|v-7|}{2} \geq \frac{46}{2} \\&|v-7| \geq 23\end{aligned}$$[/tex]

The inequality can be written as [tex]$v-7 \leq 23$[/tex] and [tex]$v-7 \geq-23$[/tex]

Step 3 of 4

First solve the inequality, [tex]$v-7 \leq 23$[/tex].

Add 7 on both sides,

[tex]$$\begin{aligned}&v-7 \leq 23 \\&v-7+7 \leq 23+7 \\&v \leq 30\end{aligned}$$[/tex]

Step 4 of 4

Solve the inequality [tex]$v-7 \geq-23$[/tex].

Add 7 on both sides,

[tex]$$\begin{aligned}&v-7 \geq-23 \\&v-7+7 \geq-23+7 \\&v \geq-16\end{aligned}$$[/tex]

The solution of the inequality in interval notation is given by [tex]$-16 \leq v \leq 30$[/tex].

In order to be labeled overweight the weight of box should be of 34.15 ounces.

Given mean of 33 ounces, standard deviation=0.7 ounces. Production of packets of 32 ounces.

Because it is normally distributed samples are solved using the z score formula.

In this Z=X-meu/st

meu is sample mean and st is population standard deviation.

We have to find the z score and then p value from the z table.

meu =33 and st=0.7

Top 5% so X when Z has a p value of 1-0.05=0.95. So X when Z=1.645.

Z=(X-meu)/st

1.645=(X-33)/0.7

X-33=0.7*1.645

X-33=1.1515

X=1.1515+33

X=34.1515 ounces.

Hence to be labeled overweight the box must have 34.15 ounces weight.

Answer:

There are two cases when the solution set of an inequality will be the empty set or the set of all real numbers.

The first case is when the inequality is always false no matter what value is chosen for the variable. For example, the inequality x > 5 has no solution because there is no value of x that is greater than 5. In this case, the solution set is the empty set.

The second case is when the inequality is always true no matter what value is chosen for the variable. For example, the inequality x > -∞ has infinitely many solutions because there is no value of x that is not greater than -∞. In this case, the solution set is the set of all real numbers.

Step-by-step explanation:

No, because one x-value corresponds to two different y-values.

The table of value is given as:

x  2   2  3  4   5

y  1   4   4   2   5

From the above table, we have:

When x = 2, y = 1 and 4

This means that 1 value of x points to multiple values of y

Answer:

1. No.

2. Yes, there is no solution here.

Step-by-step explanation:

The former:

[tex]8(5x - 3) = 6(-3x - 4); \\ 8 * 5x - 8 * 3 = 6 * (-3x) - 6 * 4; \\ 40x - 24 = -18x - 24; \\ 40x + 18x = -24 + 24; \\ 58x = 0; \\ x = 0.[/tex]

[tex]\{0\}[/tex] is our set of solutions.

The latter:

[tex]3x - 13 = 7(x + 2) - 4(x - 7); \\ 3x - 13 = 7x + 7 * 2 - 4x - 4 * (-7); \\ 3x - 13 = 7x + 14 - 4x + 28; \\ 7x - 4x - 3x = -13 - 14 - 28;\\ 0x = 55; \\ x \in \emptyset.[/tex]

Answer:

The magnitude of the resultant force acting on the box is 126.4 pounds.

Hence the correct answer is C.

Given that Kiera pulls at an angle of 30below the horizontal and with a force of 80 pounds Nathan pulls at an angle of 50 degrees above the horizontal and with a force of 85 pounds.

We need to determine the magnitude of the resultant force acting on the box.

To find the magnitude of the resultant force acting on the box, we can use the law of cosines.

The law of cosines states that for any triangle with sides of lengths a, b, and c, and an angle θ opposite to side c, the following equation holds:

c² = a² + b² - 2ab × cos(θ)

In this case, we have a triangle formed by the two forces exerted by Keira and Nathan, and we want to find the magnitude of the resultant force, which corresponds to side c.

Let's assign the following values:

a = 80 pounds (force exerted by Keira)

b = 85 pounds (force exerted by Nathan)

θ = 180° - 30° - 50° (angle opposite to the resultant force)

θ = 100°

Now we can plug these values into the law of cosines equation:

[tex]F = \sqrt{80^2 + 85^2 -2\times 80 \times 85\times \cos100}[/tex]

Solving we get,

F = 126.4

Hence the magnitude of the resultant force acting on the box is 126.4 pounds.
