masya89 [10]

Answer:

APR = 416%

EAR = 5370.60%

Step-by-step explanation:

Given:

Interest rate = 7.8% per week

Now,

In an year there are total 52 weeks

thus,

The APR (Annual percentage rate) = Interest rate × Total weeks in an year

or

APR = 8% × 52

or

APR = 416%

and, EAR ( Effective Annual Rate ) = ( 1 + r )ⁿ - 1

Here,

r is the interest rate per week

n is the total weeks in an year

thus,

EAR ( Effective Annual Rate ) = ( 1 + 8% )⁵² - 1

= ( 1 + 0.08 )⁵² - 1

= 53.7060

or

53.7060 × 100% = 5370.60%

mario62 [17]

The error in the process is we have to add the coordinates john subtracts the coordinates.

The transformation coordinates are (8, 12).

Given that

John says the transformation rule (x, y) Right-arrow (x 4, y 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2).

We have to determine

What was his error?

According to the question

A preimage or an inverse image is the 2D shape that we used to denote before any transformation.

Image is the figure that we get after transformation.

The coordinates of preimages are (4, 5).

Then,

After transformation the co-ordinates are as follows;

(4+4, \ 5+7)\\\\(8,12)

Hence, the transformation coordinates are (8, 12).

A culture started with 1,000 bacteria. After 6
Naddik [55]

Answer:

1350

Step-by-step explanation:

1000 to 1100 is an increase of 100 bacteria per 6 hours

100/6 = 16.67 bacteria per hour

16.67 * 15 hours = 250

Total bacteria should be 1100+250= 1350

hope this helps :D
