Perimeter of shaded region:

Perimeter of shaded region=area of rectangle- area of semicircle

l×w‐(πr²) - -> diameter of circle‐6m; Radius‐3

=8×6‐(3.14×3×3)

=42— 28.26=13.74m

To get the answer you divide 100 by 9 3/5.

This would get you 500/48 but simplified would be:

Mrs. Adams deposited $12,000 into an account that earns an annual simple interest rate of 3.25%. She makes no other deposits or

lisabon 2012 [21]

Answer:

<em>Mrs. Adams will earn $3,120 of interest at the end of year 8.</em>

Step-by-step explanation:

<u>Simple Interest</u>

In simple interest, the money earns interest at a fixed rate, assuming no new money is coming in or out of the account.

We can calculate the interests earned by an investment of value A in a period of time t, at an interest rate r with the formula:

$I=A.r.t$

Mrs. Adams deposited an amount of A=$12,000 into an account that earns an annual simple interest rate of r=3.25%. We must find the interest earned in t=8 years. The interest rate is converted to decimal as:

$r=3.25/100=0.0325$

The interest is then calculated:

$I=12,000\cdot 0.0325\cdot 8=3,120$

Mrs. Adams will earn $3,120 of interest at the end of year 8.

Domain is the numbers you can use
see we have rom x<-3 and x≥-3
therefor it is all real numbers for the domain

domain=all real numbers

and the range is the output
for all numbers less than -3, we have x+4, so -10+3=-7, so it extends infinetely in negative direction
and for x^2+6, you start with -3 which ends with (-3)^2+6=9+6=13, after that it gets bigger

so therefor the range is
from -∞ to -7, not including -7 and from 13 to positive infinity
in interval notation
(-∞,-7)U[13,∞)

domain=all real number
range=(-∞,-7)U[13,∞) or all real numbers except all numbers c, such that -7≤c<13
