The diameter of <u>circle A</u> is 4.8. The correct option is the second option- 4.8

<h3>Calculating the diameter of a circle </h3>

From the question, we are to determine the diameter of circle A

From the given information,

Circle A is dilated by a <u>scale factor</u> of 2.5 to form circle B

That is,

If the diameter of circle A is d, then the diameter of circle B will be 2.5d

Also, from the given information,

Diameter of circle B = 12

Then, we can write that

2.5d = 12

∴ d = 12/2.5

d = 4.8

Hence, the diameter of <u>circle A</u> is 4.8. The correct option is the second option- 4.8

Bas_tet [7]

Answer:

Amount she would have in 2 years at a simple interest of is

$5000 + ($5000 x 0.048 x 2) = $5480

Amount she would have in 2 years at a 4.1 % / year compounded semi- annually is :

$5000 x ( 1 +0.041/2)^4 = $5422.78

the first option yields a higher value in two years when compared with the second option. Thus, the first option is the best one to choose

Step-by-step explanation:

Future value with simple interest = principal + interest

Interest = principal x interest rate x time

0.048 x 5000 x 2 = 480

future value = $480 + 5000 = $5480

The formula for calculating future value with compounding:

FV = P (1 + r)^nm

FV = Future value  

P = Present value  

R = interest rate  

m = number of compounding

N = number of years

5000 x ( 1 + 0.041 / 2)^(2 x 2) = $5422.78

Answer:

The answer is 1/3x-1

Step-by-step explanation:

Let's simplify step-by-step.

5/6x−7−(1/2x−6)

Distribute the Negative Sign:

=5/6x−7+−1(1/2x−6)

=5/6x+−7+−1(1/2x)+(−1)(−6)

=5/6x+−7+−1/2x+6

Combine Like Terms:

=5/6x+−7+−1/2x+6

=(5/6x+−1/2x)+(−7+6)

=1/3x+−1

Answer:

=1/3x−1
