prove that the points A(1 , -1 ) B(5, 2) C(9, 5) are collinear.​

Answers

Answer 1

Answer:

AB= [tex]\sqrt(5-1)^2 +(2+1)^2 = \sqrt16+9 =5[/tex]

BC= [tex]\sqrt(5-9)^2 + (2-5)^2 = \sqrt16+9=5[/tex]

AC = [tex]\sqrt(1-9)^2 + (-1-5)^2 = \sqrt64+36 = 10[/tex]

So, AC = AB + BC

A, B, C are collinear points

Answers

Hello!

This is strange. It seems to give you the answer.

I am assuming your teacher would just like you to identify what a radius is.

All the same, I'll let you know the equation for finding a radius.

r= d × 2 (D is equal to diameter, and r to radius)

If you were given the diameter,, you would simply multiply it by 2 to get your radius.

The correct answer to your question is:

7 inches.

Triangle UVW has a perimeter of 11.5 units. Solve for y.

Answers

Answer:

The answer for y is 4 units

Step-by-step explanation:

The obvious question to ask in this situation is, “how many miles does Joseph travel on Mondays”? To compute, we each distance: 3 + 6 + 6 = 15.

Joseph travels 15 miles on Mondays.

Another way to work with this situation is to draw a shape that represents Joseph’s travel route and is labeled with the distance from one spot to another.

Notice that the shape made by Joseph’s route is that of a closed geometric figure with three sides (a triangle) (see figure 2). What we can ask about this shape is, “what is the perimeter of the triangle”?

Perimeter means “distance around a closed figure or shape” and to compute we add each length: 3 + 6 + 6 = 15

Our conclusion is the same as above: Joseph travels 15 miles on Mondays.

However, what we did was model the situation with a geometric shape and then apply a specific geometric concept (perimeter) to computer how far Joseph traveled.

4 units

Answers

Answer:

12.5 sq. units

Step-by-step explanation:

Divide the blue triangle into two smaller triangles.

The length of their common base = 5 units

The height of the yellow triangle = 2 units

The height of the red triangle = 3 units

The area of the yellow triangle

= (5×2)÷2

= 5 sq. units

The area of the red triangle

= (5×3)÷2

= 7.5 sq. units

The total area

= 5+7.5

= 12.5 sq. units

What is Commutative property?

According to the commutative property, the numbers on which we operate can be swapped out or moved without affecting the result. Subtraction and division are not supported by the property, but addition and multiplication are.

Given Expression

4 + 9 = 9 + ?

According to Commutative  property

A + B = B + A

for expression

4 + 9 = 9 + 4

or let missing number be x

4 + 9 = 9 + x

x = 4 + 9 - 9

x = 4

Hence the missing value is 4.

Quadrilateral CDEF is dilated by a scale factor of į to form quadrilateral C'D'E'F'.
What is the measure of side EF?

Answers

Answer:

Measure of E'F' = 9

Step-by-step explanation:

If a quadrilateral is dilated by a scale factor of [tex]\frac{3}{4}[/tex], all the sides of preimage CDEF will be dilated with the same factor to form image quadrilateral C'D'E'F'.

Scale factor = [tex]\frac{\text{Dimension of image}}{\text{Dimension of preimage}}[/tex]

[tex]\frac{3}{4}=\frac{E'F'}{EF}[/tex]

[tex]\frac{3}{4}=\frac{E'F'}{12}[/tex]

E'F' = [tex]\frac{3}{4}\times 12[/tex]

      = 9

Therefore, measure of side E'F' will be 9.

8. You sold 1000 shares of Ibex for $10.50 per share. Your broker charges you a
commission of $3.25 per thousand dollars of stock bought or sold. How much
money will be credited to your account when you sell? (Remember, commissions
are subtracted out of your transaction.)

Answers

Answer:

Amount credit in account = $10,465.875

Step-by-step explanation:

Given:

Number of shares = 1,000

Selling price of each share = $10.50

Broker charges = $3.25 per 1,000 dollar

Find:

Amount credit in account

Computation:

Total sales value = Number of shares x Selling price of each share

Total sales value = 1,000 x 10.50

Total sales value = $10,500

Total broker charges = 10,500 [3.25/1000]

Total broker charges = $34.125

Amount credit in account = Total sales value - Total broker charges

Amount credit in account = 10,500 - 34.125

Amount credit in account = $10,465.875
