Answers
Answer:
Step-by-step explanation:
a). Lines of symmetry of the circle given in the picture are,
x = 0
y = 0
y = -x
y = x
b). Since, a circle has infinite lines of symmetry (diameters) so the other lines of symmetry of the given circle will be all infinite numbers of the diameters.
c). Other symmetry this circle has a point symmetry.

A) What was the annual rate of change between 1990 and 2002?
B) Assume that the car value continues to drop by the same percentage. What will the value be in the year 2005 ?
Answers
Answer:
14.6328% , $5836.03
Step-by-step explanation:
Here we are going to use the formula
= 39000
r=?
= 11000
n=8
Hence
Hence r= 0.1463
In percentage form r = 14.63%
Now let us see calculate the value of car in 2003 that is after 12 years
we use the main formula again
= 39000
r=0.1463
= ?
n=12
Hence the car's value will be depreciated to $5840.34 (approx) by 2003.

Answers
Answer:
There are 7,344,000 seconds until the swim team meet.
Step-by-step explanation:
First we have to figure out how many seconds in a day.
There are 86,400 seconds in a day.
Then we multiply the seconds in one day by the number of days:
86,400 x 85 = 7,344,000

Write a linear function f with f(5)=7 and F(-2)=0.
Answers
Answer:
f(x)=x+2
Step-by-step explanation:
Slope= (7-0)/(5-(-2)) = 7/7 = 1
Y-intercept= 2
substitute the slope, 1, for m and the y-intercept, 2, for b to get:
f(x)=x+2
hope this helps!
The linear function f with f(5)=7 and F(-2)=0 is f(x) = x + 2
f(5) = 7
This means when x = 5 , y = 7
(5, 7)
f(-2) = 0
(-2, 0)
This implies when x = -2 , y = 0
Using the linear function formula,
y = mx + b
where
m = slope
b = y-intercept
Therefore, the function can be represented as follows:
m = 0 - 7 / -2 - 5 = -7 / -7 = 1
Therefore,
y = x + b
0 = -2 + b
b = 2
The function in relation to x can be represented as follows:
f(x) = x + 2

A college student has two different jobs. Her combined work schedules consist of no more than 48 hours in one week
Which graph best represents the solution set for all possible combinations of the number of hours she worked at her first job, and y, the number of hours she worked at her
second job, in one week?
Answer
Answers
Answer:
Choice A
Step-by-step explanation:
It's Choice A because it's the only one that kept the shaded area underneath the line, and the lines went up to only 48 hours for the first job and for the second job. Then all the possible solutions are in the shaded area.
The graph that best represents the solution set for all possible combinations that the college students could have worked is graph A.
Which graph best represents the college student's combinations?The graph that would be best is one that has all possible hour as under 48 hours on both the y and x axis.
This ensures that whatever combinations are picked, the 48 hours constraint will still stand. Graph A is the only graph with this quality and so is the best one.

Flora Kenyon made a deposit of $1,600 to her savings account on July 1. For the next year she made no other deposits or withdrawals. Her bank pays an annual interest of 3.1% compounded quarterly. Find the interest earned by Flora by July 1 of the next year.
Answers
Answer:
A = $1,650.24
Step-by-step explanation:
A = P(1 + r/n)^nt
Where
A = future value
P = present value = $1,600
r = interest rate = 3.1% = 0.031
n = number of periods = 4
t = time = 1 year
A = P(1 + r/n)^nt
= 1,600( 1 + 0.031 / 4)^4*1
= 1600( 1 + 0.00775)^4
= 1600(1.00775)^4
= 1600(1.0314)
= 1,650.24
A = $1,650.24
