<h3>Answer: Choice B</h3>

D ' (-7, 7) , E ' (-3.5, 14) , F ' (7, 10.5) , G ' (-3.5, -7)

================================================

Explanation:

Point D has coordinates x = -2 and y = 2. Multiply each by the scale factor 3.5 to get

3.5*(-2) = -7

3.5*(2) = 7

Therefore the new location is now (-7, 7) which is where point D ' is at.

The same idea applies to all of the other points

E(-1, 4) ----> E ' (-3.5, 14) after multiplying both coordinates by 3.5

F(2, 3) ----> F ' (7, 10.5) doing the same to the coordinates of point F

G(-1, -2) -----> G ' (-3.5, -7) ditto to the coordinates of point G

Extra info: the preimage DEFG enlarges to the image D'E'F'G' because the scale factor 3.5 is larger than 1.

Para encher 2/5 de uma piscina são necessários 60.000 litros de água. Qual é a capacidade dessa piscina?

natali 33 [55]

Answer:

A capacidade dessa piscina é de 150.000 litros de água.

Step-by-step explanation:

A capacidade da piscina é de x.

Para encher 2/5 de uma piscina são necessários 60.000 litros de água.

Isto implica que:

$\frac{2x}{5} = 60000$

$2x = 60000*5$

$x = \frac{60000*5}{2}$

$x = 150000$

A capacidade dessa piscina é de 150.000 litros de água.

The repayment schedule is for a $1,300 loan at 7.5% for 6 months. What is the amount for interest at payment 5?

max2010maxim [7]

Answer: The answer is $2.77.

Step-by-step explanation: Given that we have to pay the loan of $1300 at interest rate of 7.5% in 6 months. According to the table,

Amount for interest in payment 1 = $8.13,

Amount of interest in payment 2 = $6.79

and

Amount of interest in payment 3 = $5.45.

We can see here that the difference in the amounts to be paid in consecutive months will be same, i.e., the payments will form an arithmetic progression (A.P.).

The common difference = 8.13-6.79=6.79-5.45=1.34.

Therefore, amount of interest in payment 4 = $(5.45-1.34) = $4.11

and amount of interest in payment 5 = $(4.11-1.34) = $2.77.

Please see the attached modified table.

Thus, the answer is $2.77.
