7 0

Answer: R = {0, -3, -9, 5, 7}

Explanation: The range is the set of all y-coordinates for our ordered pairs.

So the range for this relation is {0, -3, -9, 5, 7}.

If $315 is invested at an interest rate of 3% per year and is compounded continuously, how much will the investment be worth in

irina [24]

Answer:

$\$412.64$

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^{rt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

e is the mathematical constant number

we have

$t=9\ years\\ P=\$315\\ r=0.03$

substitute in the formula above

$A=\$315(e)^{0.03*9}=\$412.64$

a pet store sells only dogs and cats. The ratio of dogs to cats at the pet store was 6:5. If there are 154 pets at the pet store

Y_Kistochka [10]

Step-by-step explanation:

assume the number of dogs and cats to be 6x and 5x

dogs + cats = 11x

we are given that 11x= 154

hence x=11

dogs = 6x = 6×11 = 66

PLZ HELP! 20 POINTS!

Answer:

a) The error is that, the initial value is n=1 NOT n=3

b) The sum is $a_n=a_{n+1}+5=192$

c)The explicit formula is $a_n=5n+3$

The recursive formula is $a_n=a_{n+1}+5$ ,

Step-by-step explanation:

The given arithmetic series is 8 + 13 + ... + 43.

The first term is $a_1=8$ , the common difference is $d=13-8=5$

The nth term is given by:

$a_n=a_1+d(n-1)$

We substitute the values to get:

$a_n=8+5(n-1)\\a_n=8+5n-5\\\\a_n=3+5n$

To find how many terms are in the sequence we solve the equation:

$3+5n=43\\\implies 5n=43-3\\5n=40\\n=8$

The summation notation is $\sum_{n=1}^8(3+5n)$

The error the student made is in the initial value.

It should be n=1 NOT n=3

b) The sum of the arithmetic series is calculated using:

$S_n=\frac{n}{2}(a+l)$

We substitute o get:

$S_8=\frac{8}{2}(5+43)$

$S_8=4(48)$

$S_8=192$

c) The explicit formula we already calculated in a), which is $a_n=3+5n$

The recursive formula is given as:

$a_n=a_{n+1}+d$

We substitute d=5 to get:

$a_n=a_{n+1}+5$
