The volume of the parallelepiped with adjacent edges PQ, PR, and PS is 24 cubic units.

Six parallelograms come together to form a three-dimensional shape called a parallelepiped (the term rhomboid is also sometimes used with this meaning). It is comparable to a parallelogram in the same way that a cube is comparable to a square. In Euclidean geometry, the four concepts—parallelepiped and cube in three dimensions, parallelogram, and square in two dimensions—are specified; however, only parallelograms and parallelepipeds exist in the setting of a more generic affine geometry, where angles are not discriminated.

There are three similar descriptions of a parallelepiped:

We have been that  p(−2, 1, 0), q(4, 4, 4), r(1, 4, −1), and s(3, 6, 1) are the adjacent edges of parallelepiped

PQ = Q-P = <6,3,4>

PR = R-P = <3,3.-1>

PS= S-P = <5,5,1>

[ PQ PR PS] = [tex]\begin{vmatrix}6& 3 & 4 \\ 3& 3 &-1 \\ 5 & 5 & 1 \\ \end{vmatrix}\\ \notag&& \\[/tex]

The given kilograms in pounds is 32.407952541177 pounds.

Given that there are 14.7 kilograms.

The SI unit of mass is the kilogram (kg). It is equal to the mass of the international prototype of the kilogram and One kg is approximately equal to 2.20462262184878 pounds.

One pound, the international peso, is legally defined as exactly 0. 5359237 kilograms.

To calculate the kilogram value with its corresponding value in pounds, simply multiply the quantity in kilograms by 2.20462262184878.

Pounds = kilograms × 2.20462262184878

Now, substitute kilograms=14 kilograms, we get

Pounds = 14.7× 2.20462262184878

Pounds=32.407952541177

Hence, in 14.7 kilograms there are 32.407952541177 pounds.

An inequality that represents given scenario is 5 + 2.75x ≤ 21

For given question,

The $21 means that there is a limit to the number of stops she can take using the train.

From given information, we have the following parameters:

Initial Fee = $5

Rate per stop = $2.75

Amount = $21

The inequality that represents the scenario is calculated using:

Initial Fee + Rate × Number of stops ≤ Amount

We use ≤ because the total charges must not exceed the amount.

Let the number of stops be x.

The above formula becomes

5 + 2.75x ≤ 21

Therefore, an inequality that represents given scenario is 5 + 2.75x ≤ 21

Answer:

∠ ABC = 180 - 2x

Step-by-step explanation:

AB and BC are congruent , so the triangle is isosceles with base angles congruent , that is

∠ A = ∠ C = x

the sum of the 3 angles in the triangle = 180° , then

∠ ABC + x + x = 180

∠ ABC + 2x = 180 ( subtract 2x from both sides )

∠ ABC = 180 - 2x

The solutions of the absolute value equation are x = −99 and x = 45.

Here we have the absolute value equation:

| (1/3)*x + 9| - 3 = 21

First, we can add 3 in both sides so we get:

| (1/3)*x + 9| = 21 + 3 = 24

This can be decomposed into two equations, we will get:

(1/3)*x + 9 = 24

(1/3)*x + 9 = -24

Solving these two we can get the two solutions.

The first one gives.

(1/3)*x = 24 - 9 = 15

x = 3*15 = 45

The second one gives:

(1/3)*x = -24 - 9 = -33

x = 3*-33 = -99

The solutions are x = −99 and x = 45.

Explanation:

The rule we use is [tex](\text{x}, \text{y}) \to (-\text{x}, \text{y})[/tex] when reflecting over the vertical y axis.

The x coordinate flips from positive to negative, or vice versa. The y coordinate stays the same. So a point like (-6, 5) reflects over to (6, 5). The x coordinate -6 flipped to +6 or simply 6. The y coordinate stayed at 5.

Use this idea to reflect the other points.

300 Hours will be the Interquartile range for the batteries of type A

In the given data there is a total number of 11 terms for Hours. We have to calculate the median value of Hours by using the formula :

  => Median =  [tex]\frac{n+1}{2}[/tex], and we know that Q2 = Median so Q2 can be calculated by Q2 = [tex]\frac{n+1}{2}[/tex]  => Q2 = 6 => 6th term Will be the Median.

Median = Q2 = 1300 Hours.

Now we have to Calculate Lower Quartile Q1 & Upper Quartile Q3. Since We have our Median 1300 Hours. So, the lower quartile will be :

Q1 = 1100 Hours

and, the Upper Quartile will be Q3 = 1400 Hours.

We have our Upper and Lower Quartiles. We can Calculate Interquartile Range be using the formula Q3 - Q1

   => IQR = Q3 - Q1

Putting values of Q3 and Q1, We get :

  => IQR = 1400 - 1100  => IQR = 300 Hours

Hence, the Interquartile Range IQR is 300 Hours.

Answer:

x = - 2 ± [tex]\sqrt{70}[/tex]

Step-by-step explanation:

(x + 2)² - 46 = 24 ( add 46 to both sides )

(x + 2)² = 70 ( take square root of both sides )

x + 2 = ± [tex]\sqrt{70}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{70}[/tex]

Answer: I worked the equation out and it came as false

Step-by-step explanation:

Answer:

-3.6

Step-by-step explanation:

proportional means the amount on the right is amount on the left multiplied by some coefficient - proportion. The proportion is calculated by dividing one side by another. Since you need to calculate weight based on days, you need the proportion of weight/days, so divide -0.27/9 or -0.78/26, in all cases you'll receive -0.03. This means for each day in hibernation hedgehog loses 0.03 pounds. 120 days will be 120*-0.03 which gives you -3.6

The point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.

We are given the points as:

(- 2 , - 20) and ( 9 , 79)

We will first find the slope:

Slope = m = y₂ - y₁ / x₂ - x₁

m = 79 + 20 / 9 + 2

m = 99 / 11

m = 9

Now, we have to find the point-slope equation for the line that passes through the points (- 2, - 20) and (9, 79).

The point slope equation is:

y - [y₁] = [m](x-[x₁])

Substituting the values, we get that:

y + 20 = 9 ( x + 2 )

y + 20 = 9 x + 18

9 x - y + 18 - 20 = 0

9 x - y - 2 = 0

Therefore, the point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.

Answer: a. 17

b. an=-2.5n+24.5

Step-by-step explanation:

Term number: 3, 4, 5

Terms: 17, 14.5, 12

Term 3 is 17, term 4 is 14.5, and term 5 is 12.

a. The corresponding value to term 3 is 17.

b. Slope formula: m=(y2-y1)/(x2-x1) where x=term number and y=term.

m=(17-14.5)/(3-4)

m=2.5/(-1)

m=-2.5

y=mx+b   ==> Linear equation with slope

12=-2.5(5)+b     ==> substitute a term number and it's corresponding term

b=12+12.5

b=24.5
