Answer:

A.  f(n) =0.2n+4.8

B. The y intercept is 4.8

Step-by-step explanation:

Given

a_n= 5 + 0.2(n-1)

Solving (a): Write as a function.

To do this, we simply substitute f(n) for a_n

a_n= 5 + 0.2(n-1) becomes

f(n)= 5 + 0.2(n-1)

Open Bracket

f(n) = 5 + 0.2n-0.2

Collect Like Terms

f(n) =0.2n-0.2 + 5

f(n) =0.2n+4.8

B. The y intercept.

To get the y intercept, we set n to 0

i.e

f(0) =0.2 * 0+4.8

f(0) =0+4.8

f(0) =4.8

Hence, the y intercept is 4.8

Use the table below to answer this question:
ch4aika [34]

Answer:

Step-by-step explanation:

Th average rate of change is the slope of the secant line that goes through those 2 values of x.  Of course, each value of x also has a value of y.  The coordinates for these combinations of x's and y's are:

(-1, 5) and (4, 0).  We can use the slope formula to find the average rate of change of this function without having to know what the function's equation is:

m=\frac{0-5}{4-(-1)}=\frac{-5}{5}=-1

So the average rate of change, aka slope, between those 2 points is -1

A 7 cm x 5 cm rectangle sits inside a circle with radius of 6 cm.
LenaWriter [7]

Answer:

78.04 square cm

Step-by-step explanation:

Area of shaded region = area of circle - Area of rectangle

= \pi \:  {r}^{2}  - l \times w \\  = 3.14 \times  {6}^{2}  - 7 \times 5 \\  = 3.14 \times 36 - 35 \\  = 113.04 - 35 \\  = 78.04 \:  {cm}^{2}
