Answer:

{2, 4, 6}

Step-by-step explanation:

the domain is the interval or set of valid x (input) values.

the range is the interval or set of valid y (result) values.

all we need to do is use the given x values in the functional definition and collect the result values. that is the range.

x = -1

y = 2×-1 + 4 = 2

x = 0

y = 2×0 + 4 = 4

x = 1

y = 2×1 + 4 = 6

Answer:

Colin will have $1055.46 after 7 years.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

$T = E + P$ .

In this question:

$P = 980, I = 0.011, t = 7$

$E = P*I*t$

$E = 980*0.011*7$

$E = 75.46$

Total

$T = E + P = 980 + 75.46 = 1055.46$

Colin will have $1055.46 after 7 years.

Ind the approximate increase in its area if its radius increases from mm to mm. [Recall that the area of a circle is A.]

nlexa [21]

Answer:

Increase in area of circle is $263.76$ square mm

Step-by-step explanation:

The actual question is

Find the approximate increase in its area if the radius increases from 20 mm to 22 mm.

Solution

The area of a circle of radius r is given by

$A = \pi r^2$

Area of circle of radius 20 mm is

$A_1 = \pi 20^2\\A_1 = 400\pi$ square mm

Area of circle of radius 22 mm is

$A_2 = \pi 22^2\\A_2 = 484\pi$ square mm

Increase in area of circle

$A_2 - A_1 = 484 \pi - 400 \pi \\A_2 - A_1 = 84 \pi \\A_2 - A_1 = 263.76$ square mm
