Segment AB, with endpoints A(-6,9) and B(12, -3), is dilated by a scale factor of 2/3 centered at the origin.

What are the coordinates of A'?

Enter your answer as an ordered pair, using parentheses and a comma, like this: (42,53) ​

Answers

The coordinates of A' after the dilation is (-4,6)

How to determine the coordinates of A'?

The given parameters are:

A = (-6,9)

B = (12, -3)

Scale factor, k = 2/3

The coordinates of A' is then calculated as:

A' = A * k

This gives

A' = (-6,9) * 2/3

Evaluate the product

A' = (-4,6)

Hence, the coordinates of A' after the dilation is (-4,6)

Answer:

The sum of reciprocals is 2/3.

You don't need complex numbers to solve this, but if you try to find a and b you will need complex numbers.

Step-by-step explanation:

a+b = 2

a*b = 3

1/a + 1/b = x

(a*b)*(1/a + 1/b) = (a*b)x

b + a = (a*b)(x)

2 = 3x

x = 2/3

b = 2 - a

a*(2 - a) = 3

-a^2 + 2a = 3

-a^2 + 2a - 3 = 0

a^2 - 2a + 3 = 0

let's solve the quadratic equation

a^2 - 2a + 3 = a^2 - 2a + 1 + 2 = (a - 1)^2 + 2 = 0

(a - 1)^2 = -2

[tex]a_1 - 1 = \sqrt{2}i\\a_1 = 1+\sqrt{2}i\\\\a_2 - 1 = -\sqrt{2}i\\a_2 = 1 - \sqrt{2}i\\[/tex]

these options correspond to a and b from the original question.

What is the standard form of the nymber 6.7321 * 108?
A. 6,732,100,000
B. 673,210,000
C. 67,321,000
D. 6,732,100

Answers

Answer:

673,210,000

Step-by-step explanation:

The given number is :

N = 6.7321 × 10⁸

We need to write it into the standard form.

10⁸ = 100000000

It can be calculated as follows :

6.7321 × 100000000 = [tex]\dfrac{67321 }{10000}\times 100000000[/tex]

= 673,210,000

So, the standard form of the given number is 673,210,000. Hence, the correct option is (c).

Answers

Answer:

8⁴

Step-by-step explanation:

8*8*8*8 =8⁴

8 exponent 4

Answer:

[tex]8^{4}\\[/tex]

Step-by-step explanation:

An exponent describes how many times the base is repeatedly shown. For instance:

6³

6 is the base and 3 is the exponent. Because the exponent is 3, the base is repeated that many times. Here's what I mean:

6² = 6 (6) (6)

So in 8 (8) (8) (8), the base would be 8 and this is repeated 4 times. So the exponent would be 4.

So your answer would look like [tex]8^{4}[/tex].

if x varies directly as y and x=3 when y=15 find the value of x when y=25

Answers

Answer:

Step-by-step explanation:

x=5

Answer:

x is 5.

Step-by-step explanation:

X varies directly with y, so we can use the equation x = yk (with k standing for the constant of variation) to find what the constant is. Substitute 3 for x and 15 for y

3 = 15k

Now divide both sides by 15.

3/15 = k

3/15 simplifies to 1/5.

1/5 = k

Now that we know the constant, then what we need to do is find 1/5 of 25 to get x.

1/5(25) = x

Multiply 1/5 by 25 to get 5.

5 = x

The problem is solved.

X will be 5 in this scenario.

3(2z + 3)
= -75
I need help ty

Answers

Answer:

= − 1 4

Step-by-step explanation:

Answer:

z = - 14

Step-by-step explanation:

Solving for z using basic algebra

3(2z + 3)  = -75

Step 1 distribute the 3

3 * 2z = 6z

3 * 3 = 9

now we have 6z + 9 = -75

step 2 subtract 9 from each side

9 - 9 cancels out

-75 - 9 = -84

now we have 6z = - 84

step 3 divide each side by 6

6z / 6 cancels out

-84 / 6 = -14

we're left with z = -14

is 10x-5=8x-2x + 7 -2 equivalent?

Answers

Answer:

2.5

Step-by-step explanation:

Lets simpify one side first

8x - 2x + 7 +2

8-2 = 6

so 6x

7-2 = 5

6x+9

10x - 5 = 6x +5

(You add 5 due to it being negative on the other side)

+5             +5

10x= 6x +10

-6x    -6x

4x = 10

Divide each side by 4

x = 2.5 or 10/4 or 5/2

Answer: No

Step-by-step explanation: To find whether these are equivalent, we first need to simplify the equation on the right.

8x-2x+7-2

8x-2x+5  (work-    7-2 = 5)

6x+5       (work-    8x-2x=6x) These are like terms, so we can subtract them

now that we have simplified, let's write the equations once again.

10x-5=6x+5

they are surely not equivalent

Water = 2 quarts

Orange Juice = 1quarts

Mango Juice = 2 quarts

Strawberry juice = 1 quart

Pineapple Juice = 2 quarts

So, Total mixture = Sum of all ingredients in quarts

JK = 18.86

Answer:

JK=18.8

Step-by-step explanation:

so we are given that ΔGHI ~ ΔJKL

GI~JL (because corresponding parts of similar triangles are similar)

so GI/JL=ratio of similitude=7/33

GH~JK (corresponding parts of similar triangles are similar)

and GH/JK=ratio of similitude

so:

GH/JK=GI/JL

subsitute known values

4/JK=7/33

cross multiply

7JK=132

divide

JK=132/7

simplify and round

JK≈18.8

What is the area of the polygon? Show your work.​

Answers

Answer:

33 square units

Step-by-step explanation:

Assuming that each line on this grid increases by a value of one, the area of the polygon can be determined by breaking it down into a large rectangle and two smaller triangles.

Area of the rectangle

The area of a rectangle is simply [tex]A = bh[/tex], where b represents the base and h represents the height.

Counting the size of each side, we can determine that they are 6 units for the base and 4 units for the height.

Substituting in the values, we get:

[tex]A = (6)(4)\\A = 24[/tex]

The area of the rectangle is 24 square units

Area of the triangles

The area of a triangle is simply [tex]A = \frac{1}{2} bh[/tex].

The base of each triangle is 3, and the height of each triangle is also 3.

Substituting in the values, we get:

[tex]A = \frac{1}{2} (3)(3)\\A = \frac{1}{2} (9)\\A = 9 / 2\\A = 4.5[/tex]

The area of each triangle is 4.5 square units

Area of the polygon

To get the area of the polygon, we simply add up the area of the rectangle and both triangles

[tex]A = 24 + 4.5 + 4.5\\A = 24 + 9\\A = 33[/tex]

The total area of the polygon is 33 square units.
