Triangle ABC was dilated by 50%. What is the relationship between AC and A'C'?
Elina [12.6K]

Answer:      

The length of segment AC is two times the length of segment A'C'

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

z ----> the scale factor

A'C' ----> the length of segment A'C'

AC ----> the length of segment AC

so

z=\frac{A'C'}{AC}                        

we have that

z=50\%=50/100=\frac{1}{2} ---> the dilation is a reduction, because the scale factor is less than 1 and greater than zero

substitute

\frac{1}{2}=\frac{A'C'}{AC}                

AC=2A'C'

therefore

The length of segment AC is two times the length of segment A'C'

The parabola y=x² is shifted to the right 8 units. What is the equation to the new parabola
JulijaS [17]

The new equation is

<em>Y = (x-8)² </em>.

The other way to write it is like this:  (you might not recognize it in this form)

Y = x² - 16x + 64

The equation of a function is y = 10 – 9x.Find the value of x when
USPshnik [31]

Answer:

x = 2, x = 4

Step-by-step explanation:

The equation y = 10 - 9x is a linear equation and the value of either y or x can be found by substituting the given values of either y or x.

given that y = -8, and substituting this into equation y = 10 - 9x,

we have, -8 = 10 - 9x

10 + 8 = 9x

9x = 18; dividing both sides by 9

x = 2

given that y = -26, and substituting this into equation y = 10 - 9x,

we have, -26 = 10 - 9x

10 + 26 = 9x

9x = 36; dividing both sides by 9

x = 4

If $8259 principal is invested in a savings account that pays 5.25% interest compounded continuously how much money will be in t
VMariaS [17]

Answer:

A(10) = $13,961.50

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 5.25/100

r = 0.0525 rate per year,

Then solve the equation for A

The formula is given as:

A = Pe^rt

P = 8259

r = 0.0525

t = 10 years.

Hence,

A = 8,259.00 × e^(0.0525×10)

A = $13,961.50

Therefore, the money that will be in the account after 10 years is $13,961.50

HELP ME PLEASEEE DJSUS JDIDJSJDHOSSJEJDKDHKS
Elza [17]

Answer:

(8, 20)

Step-by-step explanation:

Let's input each values of the ordered pair given as options to see which one satisfy the equation y = 16 + 0.5x

==>Option 1: (0, 18)

18 = 16 + 0.5(0)

18 = 16 + 0

18 ≠ 0

Option 1 is incorrect.

==>Option 2: (5, 19.5)

19.5 = 16 + 0.5(5)

19.5 = 16 + 2.5

19.5 ≠ 18.5

Incorrect.

==>Option 3: (8, 20)

20 = 16 + 0.5(8)

20 = 16 + 4

20 = 20

CORRECT

==>Option 4: (10, 21.5)

21.5 = 16 + 0.5(10)

21.5 = 16 + 5

21.5 ≠ 21

Incorrect.

The answer is (8, 20)
