R = 14ft , D = 3 1/3 yd


A = (pi) (r^2)

A = (22/7)(14)^2

A = 616ft^2 / 616 square feet

Kinda hard for me to explain online.. Hopefully this makes sense.

Area of circle:

A = πr²

π = 22/7, or 3.14 (simplified)

'a line all the way across' means a diameter, which is 28 cm. To find the radius, divide the diameter by 2:

28/2 = 14

Plug in 14 (the radius) to r inside the equation:

A = πr²
A = π(14)²

14² = 196

A = π(196)

π = 3.14

A = 196(3.14)

A = 615.44

615.44cm² is the area of the circle

hope this helps

The number of exports is shown as g(x). Use the data in the table below, representing both functions, to explain to your boss th
siniylev [52]

Step-by-step explanation:

Given the table:

Month              f(x) = Number of imports    g(x) = Number of exports

January (1)                3                                                1

February (2)             4                                                3

March (3)                  5                                                5

April (4)                     6                                                7

From the table, it is clear that:

Number of imports = number of month + 2

so

f(x) = x + 2

also

Number of exports  = 2(number of month) + 1

so

g(x) = 2x - 1

Therefore, number of imports equals the number of month plus one. i.e. f(x) = x + 2, which is a linear function.

If we compare it with slope-intercept form of the line

y=mx+b

Then,

slope = m = 1

y-intercept = 2

Also number of exports equals is also a linear function.

i.e. g(x) = 2x - 1

Here,

slope = m = 2

y-intercept = -1

A family wants to rent a car to go on vacation. Company A charges $50.50 and 9c per mile.
hjlf
<h3>Answer:  0.05x+10</h3>

Work Shown:

x = number of miles

Cost of company A = 0.09x+50.50

Cost of company B = 0.14x+60.50

Subtract the two expressions (B-A) to find the difference in price

B-A = (0.14x+60.50)-(0.09x+50.50)

B-A = 0.14x+60.50-0.09x-50.50

B-A = (0.14x-0.09x) + (60.50-50.50)

B-A = 0.05x+10
