I did problems like that by marking the coordinates. For example it says A was at (2.3), so you’d go over 2 and up 3. Then you’d do the same for points B and C. After that you would connect the dots with lines, and it would show that both triangles are the same size meaning that it couldn’t be a dilation, since that would make the triangle be either bigger or smaller in size. The triangles would be facing the same direction, so it couldn’t be reflected over anything or rotated. The answer would be D) translation, because the image of the triangle was translated to the right 2 and up 2 for all of the points.

Describe differences between recursive and explicit functions. Explain situations in which using a recursive or an explicit func
Misha Larkins [42]

Explanation:

An <em>explicit function</em> returns a value based only on the arguments given.

  y = f(x)

__

A <em>recursive function</em> returns a value based on the arguments given and on other values of the function.

  y = f(x, f(g(x))

Write a function to represent each problem situation Carmen deposits $1000into simple interest account.The rate for the account
kolezko [41]

The function the represent the balance in the account as a function of time t is p(t) = 1000 + 40t

<h3><u>Solution:</u></h3>

Given that,

Carmen deposits $1000 into simple interest account

The rate for the account is 4%

To find: function the represent the balance in the account as a function of time t

Given is simple interest account

The formula for simple interest is given as:

S.I = \frac{ prt}{100}

Where, "p" is the principal and "r" is the rate of interest and "t" is the number of years

In simple interest,

total amount after "t" years = principal + simple interest

Here in this question, Carmen deposits $1000

p_0 = 1000

r = 4 \% = \frac{4}{100} = 0.04

Thus we can frame a function as:

total amount after "t" years = principal + simple interest

p(t) = p_0 + (p_0 \times r \times t )

p(t) = 1000 + (1000 \times 0.04)t\\\\p(t) = 1000 + 40t

Where, p(t) is the amount after "t" years and p_0 is the principal sum

Thus the function is obtained
