Which proportion could be used to determine if the figures represent a dilation? 2/3=5/8, 2/3=8/5, 2/8=5/3, or 2/8=3/5?

Answer:

It is the odd number 1009

Step-by-step explanation:

Notice that this problem involves the addition of a number "1" per consecutive pair (a number minus the integer that immediately precedes it), so it adds "1" (one) every couple of consecutive numbers.

2018 - 2017 = 1

2016 - 2015 = 1

...

4- 3 = 1

2 - 1 = 1

That means it is the addition of 2018/2 = 1009 numbers "1". This clearly results on the number 1009, which is an odd number.

Answer:

the answer is y = x-5

a) 2p(1-2q)

b) dunno

c) k(2+13+30)

d) I’m not sure

Answer:

a) 2p(1-2q)

b) don't know what you mean by r?

c) (k+3)(k+10) using the S, P, N method

d) k²+13k+30=0

(I think you meant to write k squared as it makes more sense)

k=2

Answer:

60°

Step-by-step explanation:

90+30=120°

180-120=60°

Step-by-step explanation:

all sides of a triangle = 180

all sides of a triangle = 180

So 2 angle i.e. 90° (right angle) and 30° (given) and let third angle be x

so equation forms like

180 = 90+30+x

180 =120+x

180-120 =x

60 =x

SO THE ANSWER WILL BE 60°

Answer:   [tex]\bold{y=7cos\bigg(\dfrac{2\pi}{7}x\bigg)}[/tex]

Step-by-step explanation:

y = A cos (Bx - C) + D

The minimum is -7 and the max is 7 so A = 7 and D = 0

Period is 7.  Since P = 2π/B then 7 = 2π/B --> B = 2π/7

Nothing was stated about a phase shift so you can use any value for C. I chose C = 0.

Now, input A = 7, B = 2π/7, C = 0, & D = 0 into the equation

[tex]y=7\cos\bigg(\dfrac{2\pi}{7}x-0\bigg)+0\\\\\\\text{Simplify}:\\y=7\cos\bigg(\dfrac{2\pi}{7}x\bigg)[/tex]

Answer:

Area = 62.8 cm²

Step-by-step explanation:

In the figure attached a triangle has been given with two sides and included angle between them.

Measures of two sides are 10 cm and 13 cm.

Measure of included angle = 105°

Since area of a triangle with two sides (a and b) and included angle (θ) is,

[tex]\text{Area}=\frac{a.b.\text{sin}\theta}{2}[/tex]

        = [tex]\frac{10\times13\times \text{sin(105)}}{2}[/tex]

       = 62.79

       ≈ 62.8 cm²

Therefore area of the given triangle is 62.8 cm²

Answer:

Scalene, Acute

Step-by-step explanation:

Answer:

English,French,Vietnamese,Chinese,Ukrainian,other

Step-by-step explanation:

so basically the question is asking for us to convert the fractions into decimals and then, order the them from greatest to least

Q:how do you convert a fraction into a decimal?

A: numerator divided by denominator for example if you had to convert 7/9 into a decimal you would do 7 divided by 9!!!

English:1/4 is equivalent to 0.25

Ukrainian:1/20 is equivalent to 0.05

Vietnamese:0.02 is already in decimal form

French:1/10 is equivalent to 0.1

Chinese:0.02 is already in decimal form

Other:0.06 is already in decimal form

Now we got all the fractions converted into decimals

0.25,0.05,0.02,0.1,0.02,0.06

Now we have to put these number from greatest to least

Q:how do we put it in greatest to least?

A: if there are more zeros in the place value its more likely to be a small number for example 0.06 is smaller than 0.3

0.25 is the greatest

0.1 is the second greatest

0.02 is the third greatest

0.02 is the third greatest

0.05 is the 4th greatest

0.06 is the 5th greatest

Now we got them from greatest to least so we match the decimal numbers to the language

Starting from greatest to least is: English,French,Vietnamese,Chinese,Ukrainian,other

Answer:

5.225 miles on thursday or 209/40

Step-by-step explanation:

if we make it into decimals he runs 16.25 miles every week. on sunday he runs 6.375 miles and on tuesday it is 4.4. we are going to add what he’s run so far so

6.375 + 4.4 = 10.775 and then we will subtract that from 16.25 to get 5.225 left for thursday

Answer:

Step-by-step explanation:

( 5 - x) ( 4-x )

=5(4-x)-x(4-x)

=20-5x-4x+x^2

=x^2-9x+20

hope it helps...

Multiply first two values in brackets:

5 x 4 = 20

Multiply the outside values in the brackets:

-x * 5 = -5x

Multiply the inside terms:

-x * 4 = -4x

Multiply the last terms:

-x * -x = x^2

Place all values together:

x^2 - 5x - 4x + 20

Simplify it:

x^2 -9x + 20

Answer:

you should drag to x axis #3

Answer:

1/2

Step-by-step explanation:

Up is the y value and left is the x value.

In the point ( t,u) t is the x value and u is the y value.

Moving to the left, you subtract the value and moving up you add the value.

The answer would be (t, u) → (-t – 3, u + 8)

Answer:

Option D [[tex]y=6.61\,*\,1.55^x[/tex]] in the list of possible answers

Step-by-step explanation:

For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.

I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.

Notice that the exponential of best fit with my calculator comes in the form:

[tex]y=A\,e^{k\, x}[/tex]

with optimized parameters:

[tex]A \approx 6.6114\,\,\,and\,\,\, k=0.4378321[/tex]

Notice as well that since:

[tex]e^{0.4378321} \approx 1.5490[/tex]

the exponential best fit can also be written:

[tex]y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}[/tex]

and this expression is very close to the last option shown in your list of possible answers

Answer:

The step to take to avoid fraction is to solve for y in equation 2

Step-by-step explanation:

Given

-9x+ 4y =- 10

-9x+ 3y = 3

Required:

Step for solving using substitution (avoiding fraction)

Let -9x+ 4y =- 10  represent equation 1

and -9x+ 3y = 3 represent equation 2

The following points are to be noted

Having said that, the step to take to avoid fraction is to solve for y in equation 2

Check

[tex]-9x+ 3y = 3[/tex]

Add 9x to both sides

[tex]9x-9x+ 3y = 3 + 9x[/tex]

[tex]3y = 3 + 9x[/tex]

Divide through by 3

[tex]\frac{3y}{3} = \frac{3 + 9x}{3}[/tex]

[tex]y = \frac{3 + 9x}{3}[/tex]

Split fraction

[tex]y = \frac{3}{3} + \frac{9x}{3}[/tex]

[tex]y = 1 + 3x[/tex]

At the point, the expression of y can then be substituted in equation 1

Answer: solve for y in the second equation

Answer:

We get the final answer of -4x + 6

Step-by-step explanation:

Let's simplify step-by-step.

2x −3(2x−2)

Distribute:

= 2x+ (−3)(2x) + (−3)(−2)

= 2x+ −6x + 6

Combine Like Terms:

= 2x + −6x + 6

= (2x + −6x) + (6)

= -4x + 6

Answer:

Yuron's painting is 36 inches wide.

Step-by-step explanation:

Given that Yuron is sketching a scale drawing of a famous painting which is 54 inches wide and 72 inches long. He used a scale factor of [tex]\frac{2}{3}[/tex] to make his sketch.

We are given to find the width of Yuron’s sketch.

Let, w and w' represents the width of the famous painting and  Yuron's painting.

Then, w = 54 inches,  w' = ?

We know that the scale factor is defined by

[tex]S=\frac{Length of a side of a dilated figure}{Length of the corresponding side of the original figure}[/tex]

Therefore, we have

[tex]\frac{2}{3} =\frac{Width og Yuron's painting}{Width of the famous painting}[/tex]

[tex]\frac{2}{3} = \frac{w}{w}[/tex]

[tex]\frac{2}{3}=\frac{w}{54}[/tex]

[tex]\frac{2}{3}=\frac{2*54}{3}[/tex]

[tex]w= 36[/tex]

Thus,  Yuron's painting is 36 inches wide.

Answer:

Yuron's painting is 36 inches wide.
