Given F= {(0,1), (2,4), (4,6), (6,8)} and G= {(2,5), (4,7), (5,8), (6,9), (7,5)}(F-G) (6)
LuckyWell [14K]

Answer:

(F-G)(x) = -1

Step-by-step explanation:

The notation (F - G)(x) means to subtract each function when x = 6. According to the sets when x = 6 then F is (6,8) and G is (6,9). To subtract the functions, subtract their output values. (F-G)(x) = 8 - 9 = -1.

The equation Upper A left parenthesis t right parenthesis equals 2000 e Superscript 0.055 t gives the balance after t years of a
Pachacha [2.7K]

Answer:

a) Rate of change of amount

A'(t) =110e^{0.055t}

b) &170.79

c) 0.21

Step-by-step explanation:

We are given the following in the question:

The balance is given by the equation:

A(t) =- 2000e^{0.055t}

where t is the time in years and the initial investment is $2000 when compounded continuously.

a) Rate of change of amount

\dfrac{d(A(t))}{dt} = \dfrac{d}{dt}(2000e^{0.055t})\\\\\dfrac{d(A(t))}{dt} = 2000e^{0.055t}\times 0.055\\\\\dfrac{d(A(t))}{dt} =110e^{0.055t}

b) We have to find the value of A'(8)

A'(t) =110e^{0.055t}\\A'(8) = 110e^{0.055(8)} = 170.79

Interpretation:

The future value of 9 year investment of $2000 will be $170.79 more than the future value of 8 year investment.

c) Comparison

Approximation = $171

Actual change = $170.79

Difference =

\text{Approximation - Actual change}\\=171 - 170.79\\=0.21

Thus, the error is 0.21

Andrews [41]

Answer:  A. (x - 4, y - 2)

               B. (x + 7, y - 11)

<u>Step-by-step explanation:</u>

A) How do you get the x-coordinate of 3 to become a x-coordinate of -1?      by subtracting 4    -->    x - 4

   How do you get the y-coordinate of 5 to become a y-coordinate of 3?      by subtracting 2    -->    y - 2

The transformation is: (x - 4, y - 2)

B)  How do you get the x-coordinate of -4 to become an x-coordinate of 3?     by adding 7    -->    x + 7

    How do you get the y-coordinate of 11 to become a y-coordinate of 0?     by subtracting 11    -->    y - 11

The transformation is: (x + 7, y - 11)
