Answer:

y=3x-2

Step-by-step explanation:

3/1 simp so 3

then pick a point (1,1) I marked were what goes hope that helps you  understand        

(1)=(3)(1)+b

1=3+b

-3 each side                  

1-3=-2

-2=b

y=3x-2

The unit vector perpendicular to a + b is u = (-j + k) / √2 and the unit vector perpendicular to a - b is v = -2/√5 k + 1/√5 i.

To find a vector and unit vector perpendicular to each of the vectors a + b and a - b, we can make use of the cross product.

Given:

a = 3i + 2j + 2k

b = i + 2j - 2k

1. Vector perpendicular to a + b:

c = (a + b) x d

where d is any vector not parallel to a + b

Let's choose d = i.

Now we can calculate the cross product:

c = (a + b) x i

= (3i + 2j + 2k + i + 2j - 2k) x i

= (4i + 4j) x i

Using the cross product properties, we can determine the value of c:

c = (4i + 4j) x i

= (0 - 4)j + (4 - 0)k

= -4j + 4k

So, a vector perpendicular to a + b is c = -4j + 4k.

To find the unit vector perpendicular to a + b, we divide c by its magnitude:

Magnitude of c:

\(|c| = \sqrt{(-4)^2 + 4^2}\\= \sqrt{16 + 16}\\= \sqrt{32}\\= 4\sqrt2\)

Unit vector perpendicular to a + b:

\(u = c / |c|\\= (-4j + 4k) / (4 \sqrt2)\\= (-j + k) / \sqrt2\)

Therefore, the unit vector perpendicular to a + b is u = (-j + k) / sqrt(2).

2. Vector perpendicular to a - b:

e = (a - b) x f

where f is any vector not parallel to a - b

Let's choose f = j.

Now we can calculate the cross product:

e = (a - b) x j

= (3i + 2j + 2k - i - 2j + 2k) x j

= (2i + 4k) x j

Using the cross product properties, we can determine the value of e:

e = (2i + 4k) x j

= (0 - 4)k + (2 - 0)i

= -4k + 2i

So, a vector perpendicular to a - b is e = -4k + 2i.

To find the unit vector perpendicular to a - b, we divide e by its magnitude:

Magnitude of e:

\(|e| = \sqrt{(-4)^2 + 2^2}\\= \sqrt{16 + 4}\\= \sqrt{20}\\= 2\sqrt5\)

Unit vector perpendicular to a - b:

\(v = e / |e|\\= (-4k + 2i) / (2 \sqrt5)\\= -2/\sqrt5 k + 1/\sqrt5 i\)

Therefore, the unit vector perpendicular to a - b is \(v = -2/\sqrt5 k + 1/\sqrt5 i.\)

The statement holds for n=k+1.

By mathematical induction, we have proven that 1·1!+2·2!+···+n·n!=(n+1)!−1 for all positive integers n.

What are integers?

Integers are a set of numbers that include whole numbers (positive, negative, or zero) as well as their opposites.

We will use mathematical induction to prove the statement.

Base case: Let n=1. Then the left-hand side of the equation is 1·1!=1 and the right-hand side is (1+1)!=2!-1=1. Therefore, the statement holds for n=1.

Induction hypothesis: Assume that the statement holds for some positive integer k, i.e., 1·1!+2·2!+···+k·k!=(k+1)!−1.

Inductive step: We need to show that the statement also holds for k+1, i.e., 1·1!+2·2!+···+(k+1)·(k+1)!=(k+2)!−1.

We have:

1·1!+2·2!+···+k·k!+(k+1)·(k+1)!=k!+1·1!+2·2!+···+k·k!+(k+1)·(k+1)!=k!+(k+1)!−1+(k+1)·(k+1)!=k!(k+1+1)+(k+2)!−1=(k+1)!(k+2)−1=(k+2)!−1,

where we have used the induction hypothesis in the second step and simplified in the fourth step.

Therefore, the statement holds for n=k+1.

By mathematical induction, we have proven that 1·1!+2·2!+···+n·n!=(n+1)!−1 for all positive integers n.

Answer:

3

Step-by-step explanation:

First right out all the data in numerical order from left to right.

2, 2, 2, 3, 4, 5, 7

The median is the middle number in the set.  If there is an even amount of data points, find the average of the two middle numbers.  If there is an odd number of data points, like in this data set, just take the middle number as you median.

There are 7 data points in this set so the fourth number in the set written in numerical order would be your median.

When writing this set out in numerical order, repeated numbers must be repeated, we find that the fourth, or middle, number is 3.  Therefore, 3 is the median of this data set.

Answer:

n = 4.

Step-by-step explanation:

-3(n + 2) - 5 = -23

Distribute the -3.

-3n - 6 - 5 = -23

Combine like terms.

-3n - 11 = -23

Add 11 to both sides.

-3n = -12

Divide both sides by -3.

Step-by-step explanation:

Please see the attached picture for full solution.

The total number of toys in his collection is 400

Let total number of toys = x

Number of toys on wall = 368

Number in display case = 0.08x

Total toys = 368 + 0.08x

x = 368 + 0.08x

x - 0.08x = 368

0.92x = 368

x = 368/0.92

x = 400

Therefore, the total number of toys is 400.

The x-intercept is 19.

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Where x₁ - x coordinate; y₁ - y coordinate

m - slope

Given the equation as;

Y=10x/3+19

Then;

the slope m = 10/3

The intercept is 19.

Hence, the x  intercept is 19.

The median length of 5.8 feet tells us that half of the dolphins in the pod have a length less than or equal to 5.8 feet, while the other half have a length greater than or equal to 5.8 feet.

It provides information about the central tendency of the length distribution within the pod. However, the median does not provide specific details about the range or distribution of dolphin lengths. It only gives us a measure of the middle value. This means that there could be dolphins with lengths significantly smaller or larger than 5.8 feet within the pod.

For example, the pod could consist of dolphins with lengths ranging from very short to very long, with some dolphins being close to 5.8 feet and others being much further away. To gain a more comprehensive understanding of the length distribution in the pod, additional statistical measures like the mean, standard deviation, and range would be necessary. These measures would provide insights into the average length, the spread of lengths around the average, and the minimum and maximum lengths observed within the pod.

Answer:

B) 176 ft²

Step-by-step explanation:

The picture below is the attachment for the complete question. The figure has 3 halves of a circle and a square . The area of the figure is the sum of their area.

Area of a square

area = L²

where

L = length

L = 9 ft

area = 9²

area = 81 ft²

Area of the 3 semi circles

area of a single semi circle = πr²/2

For 3 semi circle = πr²/2 + πr²/2 + πr²/2 or 3 (πr²/2)

r = 9/2 = 4.5

area of a single semi circle = (3.14 × 4.5²)/2

area of a single semi circle = (3.14 × 20.25 ) /2

area of a single semi circle = 63.585 /2

area of a single semi circle = 31.7925

Area for 3 semi circles = 31.7925  × 3 = 95.3775  ft²

Area of the composite figure =  95.3775  ft² + 81 ft² = 176.3775  ft

Area of the composite figure ≈ 176 ft²

The car's dashboard shows proportions of 8 lines which means that this can be used to find the rate of fuel consumption by the car.

After 255 miles travelled, Vikram's car shows the arrow at the 5th proportion. This means that the amount of fuel in terms of proportion used is:

= 8 - 5

= 3

In decimals, this is:

= Proportions used / Total proportions

= 3 / 8

The suitability of kilograms as a unit of weight depends on the context and the specific requirements of the situation.

However, in most cases, kilograms are considered more appropriate for measuring weight compared to other units like pounds or ounces.

One reason for the preference of kilograms is its widespread use in the scientific community and the International System of Units (SI).

Kilograms are the base unit of mass in the SI system, which is widely adopted internationally for consistency and standardization.

This makes kilograms more suitable for scientific research, engineering, and global communication.

Additionally, kilograms provide a more consistent and easily relatable scale for weight measurements.

The decimal system used with kilograms allows for straightforward conversions and calculations.

It also aligns with the understanding of weight in everyday life, such as when discussing the weight of objects or individuals.

In contrast, units like pounds or ounces may be more commonly used in certain regions, but they lack the same level of global acceptance and scientific relevance.

While there may be specific cases where other units are more appropriate, kilograms generally offer a more practical and standardized approach to measuring weight.
