WHAT IS THE CORRECT SCALE FACTOR?

Mathematics
1 answer:
topjm [15]3 years ago
3 0

Answer:

3/7

Step-by-step explanation:

To find the scale factor we have to compare the initial points to the final points, we can do this by observing only one corner of the triangle, as it will apply to the entire triangle.

<u><em>Let's look at C and C'</em></u>

The coordinates of C are (7,-7)

The coordinates of C' are (3,-3)

<u><em>To make things simpler let's find the relationship between our x-coordinates, then test it on our y-coordinates</em></u>

We essentially have to find what 7 is multiplied by to get 3, we'll make an equation

7x=3

Solve for x by dividing both sides by 7

x=3/7     <------- This shows that our scale factor in this case is 3/7

<em><u>Now we will test this on our y-coordinates</u></em>

-7(3/7)=-3

\frac{-7(3)}{7}=-3?

The 7's on the top and bottom simplify to -1

-1(3)=-3?

-3=-3 <------- This is true! So we know this is our scale factor for the entire triangle

Hope I could help!

Suma de polinomios de 5׳+3 + 2׳-ײ+1 porfavor ayuda​
Sidana [21]

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<33<3<3<3<3

Let's simplify step-by-step.

5x^3 + 3 + 2x^3 − x^2 + 1

= 5x^3 + 3 + 2x^3 + −x^2 + 1

Combine Like Terms:

= 5x^3 + 3 + 2x^3 + −x^2 + 1

= ( 5x^3 + 2x^3 ) + ( −x^2 ) + ( 3 + 1 )

= 7x^3 + −x^2 + 4

Answer:

= 7x^3 − x^2 + 4

Tony gets paid $5 per hour to babysit his cousin. This
Kaylis [27]

<em>Answer:</em>

a

<em>Step-by-step explanation:</em>

lets substitute 5 into every equation. (using 5 every time won't work every time ofc)

ok so 5(x+6)=55 would simplify into <em>5x+30=55</em> which in this case would be <em>5(5)+30=55 </em>

and 25 plus 30 (obviously) = 55

so A is the right answer

48,919 ÷ ? = 489.19<br> 489,190 ÷ 1,000 =?<br> 4,891,900 ÷ ? = 489.19<br> ? ÷ 100,000 = 489.19
musickatia [10]

Answer:

  • 100
  • 489.190
  • 10,000
  • 48,919,000

Step-by-step explanation:

Each factor of 10 in the divisor causes the decimal point to move 1 place to the left.

a) The decimal point has moved 2 places to the left. The divisor is 10^2 = 100.

b) The divisor is 10^3, so the decimal point will move 3 places to the left.

  489.190

c) The decimal point has moved 4 places to the left, so the divisor is 10^4 = 10,000.

d) The divisor is 10^5, so the decimal point in the quotient if 5 places to the left of where it is in the dividend. Moving the quotient's decimal point 5 places to the right gives ...

  48,919,000

_____

<em>Additional comment</em>

An exponent signifies repeated multiplication. Here, we're concerned with repeatedly multiplying (or dividing) by factors of 10. The exponent indicates the number of factors: 10·10 = 10^2 = 100. It also matches the number of zeros following the 1 in the product. 1000 = 10^3 has 3 zeros after the 1, for example.

The sum of three consecutive integers is 267. What is the largest integer?
Stella [2.4K]

Answer:

let integers be x,2x, 3x respectively

x+2x+3x= 267

6x= 267

x=267/6= 44.5

2x= 44.5*2= 89

3x= 44.5*3= 133.5

largest integer = 133.5

hope it helps
