a. Point P on the line and the direction vector v of the line can be expressed as P = (x0, y0, z0) + t(a, b, c).

b. The distance from the origin to the line -x=y+1, z=2 is the shortest distance between a point and a line.

Here (x0, y0, z0) is a point on the line and (a, b, c) is the direction vector. To find (x0, y0, z0) and (a, b, c), we need more information about the line.

This formula involves taking the dot product of the direction vector of the line and the difference between a point on the line and the origin. Again, we need more information about the line in order to calculate this distance.

Without more information about line L, it is not possible to find the point P or the distance from the origin to the line.

The number of animals left in the wild after 4 years is approximately 306.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

We are using the concept of compound interest to solve the given problem.

The formula to find the final amount in compound interest is,

A = P (1 + r) ^t

Here P = 400

r = -6.5% = -0.065 (negative sign because the rate is decreasing)

t = 4 years

Substituting the values,

A =400 (1 - 0.065)⁴

  = 305.71 ≈ 306

Hence there will be 306 animals left in the wild after 4 years.

Answer: Let's call the height of the building "h".

The length of the shadow cast by the building is 5 feet, and the length of the shadow cast by the yardstick is also 5 feet. This means that the ratio of the height of the building to the length of its shadow is the same as the ratio of the height of the yardstick to the length of its shadow.

h / 5 = 1 / 5

Cross-multiplying, we get:

h = 5 * 1 / 5

h = 1

So the building is 1 foot tall.

The number of Gallons of paint that Daniel will need is; 3 gallons

The parameters given are;

Height of each wall = 78 inches = 78/12 = 6.5 ft

Length of wall 1 = 7 ft

Length of wall 2 = 6 ft

Length of wall 3 = 7 ft

Area of wall 1 = 6.5 * 7 = 45.5 sq.ft

Area of wall 2 = 6.5 * 6 = 39 sq.ft

Area of wall 3 = 6.5 * 7 = 45.5 sq.ft

Total area = 45.5 + 45.5 + 39

= 130 sq.ft

1 gallon of paint will cover 300 square feet of wall space

Number of gallons required = 300/130

= 2.3 gallons

The total number of toys in Bashir's collection is 160.

A percentage is a number or ratio that can be expressed as a fraction of 100.

Let N represent the total number of toys in Bashir's collection

Since 136 of his toys are on the wall and 15% of the toys are in the display. We can write:

136 + (15% of N) = N

136 + (15/100 * N) = N

136 + 0.15N = N

N - 0.15N = 136

The values of the expression following the collection of like terms, rearranging and factoring are presented as follows;

1.1 4·x + 5·a + 3·a + x - 6 = 5·x + 8·a - 6

1.2. 6·a·b + 2·b - 16·a - 2 = 2·(3·a·b + b - 8·a - 1)

1.3. 1024000 : 360000 : 180000 = 256 : 90 : 45

1.4. 150 min : 3 hours = 5 : 6

A mathematical expression comprises of mathematical symbols, numbers and variable, properly arranged to represent a value.

The simplification of the expressions can be presented as follows;

1.1. 4·x + 5·a + 3·a + (x - 6)

The terms in the above expression can be rearranged as follows;

4·x + 5·a + 3·a + (x - 6) = 4·x + x + 5·a + 3·a - 6

4·x + x + 5·a + 3·a - 6 = 5·x + 8·a - 6

Therefore, whereby the expression in the question is; 4·x + 5·a + 3·a + (x - 6), we get;

1.2. Whereby the possible expression in the question is; 6·a·b + 2·b - 16·a + (-2), we get;

The factor common to the terms of the expression 6·a·b + 2·b - 16·a + (-2) is 2. Therefore by factoring the expression, we get;

1.3. 1024000: 360,000 : 180,000

The expression is a ratio of the form a : b : c

Dividing each term in the ratio by 1,000, we get

1024000 ÷ 1000 : 360,000 ÷ 1000 : 180,000 ÷ 1000 = 1024 : 360 : 180

1024000: 360,000 : 180,000 = 1024 : 360 : 180

The common factors of 1024, 360 and 180 are; 1, 2, and 4

Therefore, the GCF of 1024, 360, and 180 is 4

Dividing the terms of the ratio 1024 : 360 : 180 by 4, we get;

1024 ÷ 4 : 360 ÷ 4 : 180 ÷ 4 = 256 : 90 : 45

Therefore;

1.4 150 min : 3 hours

The above ratio can be simplified by rewriting the ratio using unit conversion as follows;

3 hours = 180 minutes, therefore;

150 min : 3 hours = 150 min : 180 min

150 : 180 = 5 : 6

The value of the equation is x = 4 and x = -5 ± √10i

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

( x - 4 ) / ( x + 5 ) + 9 / ( x² + 11x + 30 ) = 1/( x + 6 )

On simplifying the equation , we get

( x - 4 ) / ( x + 5 ) + 9 / ( x + 5 ) ( x + 6 ) = 1/( x + 6 )

Multiply the equation with the LCM , we get

( x - 4 ) ( x + 5 ) ( x + 6 ) + 9 ( x - 5 ) = ( x - 5 ) ( x + 5 )

x³ + 7x² - 14x - 120 + 9x - 45 = x² - 25

Subtracting x² on both sides of the equation , we get

x³+ 6x² - 5x - 165 = -25

Adding 25 on both sides of the equation , we get

x³+ 6x² - 5x - 140 = 0

Hence , the solution to the equation is x = 4 ,  -5 ± √10i

So , the larger solution is x = 4

And , the smaller solution is x = -5 ± √10i

Let the width of the path be represented by x.

The total width of the pool and the path would then be 16 + 2x (for the two shorter sides) and 28 + 2x (for the two longer sides).

The area of the pool itself is 16 × 28 = 448 square meters.

The area of the combined pool and path is 864 square meters.

So the area of just the path is:

864 - 448 = 416 square meters

The area of the path can also be expressed as the area of the larger rectangle (16 + 2x) × (28 + 2x) minus the area of the pool (16 × 28).

So we can set up the equation:

(16 + 2x) × (28 + 2x) - 448 = 416

Expanding the left side and simplifying:

4x^2 + 88x - 480 = 0

Dividing by 4:

x^2 + 22x - 120 = 0

Using the quadratic formula:

x = (-22 ± sqrt(22^2 - 4(-120)))/2

x = (-22 ± 26)/2

x = 2 or x = -24

The width of the path cannot be negative, so the width of the path is 2 meters.

A = 441π mm²

To 1 decimal place, 441π can be approximated to 1393.1 mm². So, the area of the circle with a radius of 21 mm is approximately 1393.1 mm² to 1 decimal place.

Step-by-step explanation:

The probability of a defect is 5.7330 x [tex]10^{-5}[/tex] and the number of defects is 5.73.

To calculate the probability of a defect, we need to find the area under the standard normal curve that lies outside of the process control limits of 9.75 ounces and 10.25 ounces. We can use the standard normal distribution table to find this area.

First, we need to standardize the weight limits as follows -

[tex]Z_{lower}[/tex] = (9.75 - 10) / 0.25 = -4

[tex]Z_{upper}[/tex] = (10.25 - 10) / 0.25 = 4

Next, we will find the area under the standard normal curve that lies outside of these limits as follows -

P(Defect) = P(Z < -4) + P(Z > 4)

Using a standard normal distribution table, we can find that P(Z < -4) = 2.8665 x   [tex]10^{-5}[/tex]  and P(Z > 4) = 2.8665 x  [tex]10^{-5}[/tex] .

So, the total probability of a defect is -

P(Defect) = 2.8665 x  [tex]10^{-5}[/tex]  + 2.8665 x  [tex]10^{-5}[/tex]  = 5.7330 x  [tex]10^{-5}[/tex]

Finally, we will find the number of defects for a 1,000-unit production run as follows -

The number of defects = 1000 * 5.7330 x  [tex]10^{-5}[/tex]  = 5.73 (rounded to the nearest whole number).
