Which scale factors produce a contraction under a dilation of the original image?

Leokris [45]

Answer:

1/2

-1/2

Step-by-step explanation:

we know that

If a dilation produce a contraction that means that the absolute value of the scaling factor is less than 1

If a dilation produce an enlargement that means that the absolute value of the scaling factor is greater than 1

Verify each case

case 1) 2

$\left|2\right|=2$

$2 > 1$ ----> is a enlargement

case 2) 1/2

$\left|1/2\right|=1/2$

$1/2 < 1$ ----> is a contraction

case 3) -2

$\left|-2\right|=2$

$2 > 1$ ----> is a enlargement

case 4) -1/2

$\left|-1/2\right|=1/2$

$1/2 < 1$ ----> is a contraction

Ernesto has $20 in an account. The interest rate is 10% compounded annually.

chubhunter [2.5K]

The interest Ernesto will earn in 1 year to the nearest cent is 2200 cents.

Given the following data:

Principal = $20.

Interest rate = 10%

Time = 1 year.

To calculate how much interest Ernesto will earn in 1 year to the nearest cent:

<h3>How to calculate compound interest.</h3>

Mathematically, compound interest is given by this formula:

$B=P(1+r)^t$

Where:

B is the balance.

P is the principal or starting amount.

R is the interest rate.

T is the time measured in years.

Substituting the given parameters into the formula, we have;

$B=20(1+0.1)^1\\\\B=20(1.1)$

B = $22.

To cents:

B = $22 \times 100$

B = 2200 cents.

Which of the following represents the set of possible rational roots for the polynomial shown below 2x^3+5x^2-8x-20=0

olya-2409 [2.1K]

The questioner wants us to list all possible roots by applying the Rational Roots theorem

factors of constant term (-20) = +/- 1, +/-2, +/-5, +/-10, +/-20 WE call these factors p.

factors of leading coefficient (2) = +/- 1, +/-2 (call these q)

then possible roots are p/q = +/-1/1, +/- 1/2 , +/- 5/1 , +/- 5/2 and so on.
