If in parallelogram ABCD, AB = 14cm. The altitude corresponding to AB is 6 cm and the altitude corresponding to BC is 7 cm. The AD is 8.57.

Given data:

AB= 14cm

Altitude corresponding  AB =6cm

Altitude corresponding to BC =7cm

So,

1/2 × AB × altitude 1 = 1/2 × AD × altitude 2

AB × altitude 1 =AD × Altitude 2

10 × 6 = AD × 7

60 = AD × 7

AD = 60/7

AD = 8.57

Therefore we can conclude that AD is 8.57.

This proof shows that the zero vector is in Col A, the vector Ax C Aw is in Col A, and c.Ax/ is in Col A, given a scalar c. This proves Theorem 3, which states that an element in Col A has the form Ax for some x in Rn.

a. The zero vector is in Col A because it is the result of multiplying the zero vector in Rn by matrix A. Therefore, A(0) = 0, which is the zero vector in Col A.

b. To show that the vector Ax C Aw is in Col A, we need to show that Ax C Aw can be written in the form A(x + w) for some vectors x and w in Rn. Since Ax and Aw are in Col A, they can be written as A(x) and A(w) for some vectors x and w in Rn. Therefore, Ax C Aw = A(x + w). Thus, the vector Ax C Aw is in Col A.

c. Given a scalar c, we need to show that c.Ax/ is in Col A. We can rewrite c.Ax/ as cA(x). Since A(x) is in Col A, then cA(x) is also in Col A. Therefore, c.Ax/ is in Col A.

This proof shows that the zero vector is in Col A, the vector Ax C Aw is in Col A, and c.Ax/ is in Col A, given a scalar c. This proves Theorem 3, which states that an element in Col A has the form Ax for some x in Rn.

Answer:

Manish covers more distance. He covers 960m whereas Santosh only covers 480m

Step-by-step explanation:

First we compute the perimeter of the square track

Perimeter of a square of side a = 4a

Here a = 80m

Perimeter of the square of side 80 =>  4 x 80 = 320 m

Since Manish runs 3 times around it, total distance covered = 3 x 320 = 960

The perimeter of a rectangle with length L and breadth B = 2(L + B)

So perimeter of the rectangular track = 2(80 + 40) = 2 x 120 = 240

Since Santosh ran twice around this, total distance covered = 2 x 240 = 480

Answer: 5 4/7

Step-by-step explanation: First, we need to change both 1 5/7 and 3 1/4 into an improper fraction. So:

[tex]1 \frac{5}{7}[/tex] = [tex]\frac{12}{7}[/tex]

[tex]3\frac{1}{4}[/tex] = [tex]\frac{13}{4}[/tex]

So, now we need to cross-multiply 12/7 and 13/4.

That'd be 156/28

But wait. We analyze that 156 and 28 can be reduced by 4

So, 156 divided by 4 is 39, and 28 divided by 4 is 7. So now our improper fraction is 39/7. To make it an improper fraction, we divide 39 by 7, which would give us 5 4/7. I hope this helped!

The truck is 6.325 feet long.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

So the percentage actually means a part per 100.

Percentage is usually denoted by the symbol '%'.

Given that,

A car is 5.5 ft long. A truck is 15% longer than the car.

Length of car = 5.5 feet

Length of truck = 5.5 + (15% × 5.5)

                         = 5.5 + [(15/100) × 5.5]

                         = 5.5 + (0.15 × 5.5)

                         = 5.5 + 0.825

The first and fourth functions agrees that have  y-intercepts have a difference of 3 and the slopes are both negative.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Let us find the slope of first graph

m=-3+2/2=-1

q = 34

r = 91

Step-by-step explanation:

If each term (after the first two terms) is the sum of the previous two terms:

[tex]\implies p+23=q[/tex]

[tex]\implies 23+q=57[/tex]

[tex]\implies q+57=r[/tex]

Solve the second equation for q:

[tex]\implies 23+q=57[/tex]

[tex]\implies 23+q-23=57-23[/tex]

[tex]\implies q=34[/tex]

Substitute the found value of q into the first equation and solve for p:

[tex]\implies p+23=34[/tex]

[tex]\implies p+23-23=34-23[/tex]

[tex]\implies p=11[/tex]

Substitute the found value of q into the third equation and solve for r:

After 4 years of recycling and re-using, approximately average one-half of the original 350,000 cans produced by the soft drink company would still be in use.

1. 350,000 cans produced in 1 year

2. 50% of cans recycled each year

3. 50% of 350,000 cans = 175,000 cans

4. After 4 years, 175,000 cans still in use.

Each year, it is predicted that about half of all aluminum cans will be recycled. This means that if a soft drink company produces 350,000 cans one year, then after four years, approximately one-half of the original cans produced would still be in use. This can be calculated by taking the initial number of cans produced (350,000), multiplying it by fifty percent (50%), and then multiplying that number by four (4). The final result is that after four years of recycling and re-using, approximately 175,000 cans would still be in use.

You can use a compass and set its angle such that it the radius of the circle that it will draw is less than that of WX's length but longer than its half. Use it to make 4 arcs.

Making 4 arcs (2 arcs up and down from W and 2 arcs up and down from X which intersect the previous two arcs) with the circle of radius smaller than the length of  WX will give two points on a perpendicular bisector.

How to find the perpendicular bisector of a line segment with the help of a compass and a straightedge?

The construction steps are as follows:

Let the line segment to be bisected(divided into two equal parts) by a perpendicular line(that perpendicular bisecting line is called the perpendicular bisector of the given line segment) be WX

Take a compass and set its radius length smaller than the length of WX and longer than half of WX

Put the tip of the compass on W and make an arc upside of WX

Now make an arc downside of WX

Repeat the above two steps but now with the tip being on X such that two new arcs intersect the previous two arcs.

Use a straightedge and join both the points of intersection of arcs.

The obtained line is the perpendicular bisector of the line segment WX

Using the above method, we get the perpendicular bisector of WX  shown in the below-attached figure.

Thus,

Making 4 arcs (2 arcs up and down from W and 2 arcs up and down from X which intersect the previous two arcs) with a circle of radius smaller than the length of  WX will give two points on a perpendicular bisector.

The prime factorization of the radicand 2 is 9√15.

A number can be expressed as the product of its prime components through the process of prime factorization. A number with precisely two elements, 1 and the number itself, is said to be a prime number.

As an illustration, let's use the number 30. We know that 30 = 5 × 6, but 6 is not a prime number. The number 6 can further be factorized as 2 × 3, where 2 and 3 are prime numbers. Therefore, the prime factorization of 30 = 2 × 3 × 5, where all the factors are prime numbers.

Given that,

x= 3√135

Solving the equation further using the rule √A*B = √A*√B

x= 3√9*15

x= 3√9*√15

x=3*3*√15
