VashaNatasha [74]

Answer:

(x-5;y+6)

Step-by-step explanation:

1) the difference between the coordinates before translation and after the translation is*: Δx=-5; Δy=+6, then

2) the rule of the translation is: (x-5;y+6).

* for example, the red dot. The difference for X is: -2-3=-5. The difference for Y is: 2--4=+6.

If a sum invested gains 10% each year how long will it be before it has doubled its<br> value?
Anika [276]

Using an exponential equation, it is found that it will be 7.3 years before the value is doubled.

The equation for an increasing <u>exponential function</u> is given by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial amount.
  • r is the growth rate, as a decimal.

In this problem:

  • Gains 10% each year, thus r = 0.1.

The doubling time is t for which A(t) = 2A(0), then:

A(t) = A(0)(1.1)^t

2A(0) = A(0)(1.1)^t

(1.1)^t = 2

\log{(1.1)^t} = \log{2}

t\log{1.1} = \log{2}

t = \frac{\log{2}}{\log{1.1}}

t = 7.3

It will be 7.3 years before the value is doubled.

José plotted points on a coordinate plane to represent the vertices of a rectangle. The first
Tema [17]

Jose's rectangle must have equal and parallel opposite sides

The coordinates of the other points could be C(7,5) and D(7,1)

<h3>How to determine the other points?</h3>

The coordinates are given as;

A = (2,5).

B = (2,1).

To form a rectangle, each of the remaining points must have the same y-coordinates as points A and B.

So, we have:

C = (x,5)

D = (x,1)

Also, the remaining points must have the same x-coordinates.

i.e.

Cx = Dx

From the list of options, we have:

C(7,5) and D(7,1)

Hence, the coordinates of the other points could be C(7,5) and D(7,1)
