Circle A is defined as (x-5)^2+(y-6)^2=16, and circle B is defined as (x+3)+(y+2)^2=9. Which transformation of circle A shows that circle B is similar?

Answers

Answer: The answer is D

Step-by-step explanation:

Circle A has translated 2 units to the right and 8 units up to produce circle B ad circle B was reduced by a factor of 3/4

Transformation of coordinates

Given the equation of circles A and B defined as (x-5)^2+(y-6)^2=16 and (x+3)+(y+2)^2=9

The scale factor of a dilation is given as:

k = √9/√16

k = 3/4

From the centers, we can see that circle A has translated 2 units to the right and 8 units up to produce circle B

Cuánto tiempo debe transcurrir para que un capital de $3,000.00 alcance un monto de $7,000.00, si la inversión se hizo con 5% de interés simple mensual?

Answers

Answer:

27 years approx

Step-by-step explanation:

Given data

Principal P= $ 3,000

Final amount A= $ 7000

Rate r= 5%

The simple interest expression is

A=P(1+rt)

substitute and solve for t

7000=3000(1+0.05t)

7000=3000+150r

7000-3000=150r

4000=150t

t= 4000/150

t= 26.66

Hence, the time is 27 years approx

-(4k^2-13k-12)+5k^2-8k How would I be able to write this in standard form with the greatest exponent being first.

Answers

Answer:

Step-by-step explanation:

Negative sign is outside the parenthesis. So, each term of (4k² - 13k -12) should be multiplied by (-1)

-(4k² - 13k -12) + 5k² - 8k = 4k²*(-1) - 13k*(-1) - 12*(-1) + 5k² - 8k

= -4k² + 13k + 12 +5k² - 8k

Combine like terms,

= -4k² + 5k² + 13k - 8k + 12

= k² + 5k + 12

Like terms are the terms with same variable with same exponent.

(-4k² ) and 5k² are like terms

13k and (-8k) are like terms
