Answer:

$8 1:00pm

$10 1:15 pm

Step-by-step explanation:

the time between 10 am and 1 pm is 3 hours.

on the graph, it shows that at 3 hours you will have to pay 8 dollars.

If the time is a second over 3 hours, which it is for 1:15, you will have to pay the extra $2, which makes it a total of $10.

Answer:

C- where n (greater than or equal to ) 1

Step-by-step explanation:

C- where n (greater than or equal to ) 1

Because in that sequence 0 doesn't make sense since 160 * 1/2 = 80 ^ 0 = 1. Doesn't make sense since there's no "1" in that sequence.

It's not "any number" because It can't be negative nor a decimal.

So, C.

:) hope this helps

Rosita should use the domain in option C : n ≥ 1, where n is an integer to generate the sequence for the function T(n) = 160 ( [tex]\frac{1}{2}[/tex] )ⁿ.

Functions are defined as the relation which is mapped from a set A to a set B such that it satisfies the property that an element in set A will only map to one element in B.

If f is a function defined from a set A to a set B, then all the elements of A which has an image on B is called the domain of the function f.

Here the given function is,

T(n) = 160 ( [tex]\frac{1}{2}[/tex] )ⁿ

And we know the first element is 80.

T(n) = 80 if and only if n = 1

T(1) = 160 ( [tex]\frac{1}{2}[/tex] )¹ = 160 / 2 = 80

Similarly,

T(2) = 160 ( [tex]\frac{1}{2}[/tex] )² = 40

T(3) = 160 ( [tex]\frac{1}{2}[/tex] )³ = 20

T(4) = 160 ( [tex]\frac{1}{2}[/tex] )⁴ = 10

and it goes on.

So the values of n are all integers where n ≥ 1.

Hence the domain of the function T(n) = 160 ( [tex]\frac{1}{2}[/tex] )ⁿ that Rosita should use for T to generate the sequence is  n ≥ 1 where n is an integer.

How many times does 5 go into 4? One time. Write -1.

-1

What are you left with? 5-4=1 --> 1/4. Write 1/4

Answer is -1 1/4

Answer:

-1 [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

We can think of 5/4 as 4/4 + 1/4.

Since 4/4 is equal to 1, we can change this to 1 + 1/4

This can be simplified to 1 [tex]\frac{1}{4}[/tex].

Add a negative sign since the number is negative:

Step-by-step explanation:

Answer: Positive

Step-by-step explanation:

As we can see that common difference is increasing to one more digit after every term

so it means

a21 = 231

Answer:

1. a_n = a_(n-1) + n where a_1 is 1 or a_n = n(n+1)/2

2. 231

Step-by-step explanation:

Notice that from 1 to 3, you add 2; from 3 to 6, you add 3; from 6 to 10, you add 4, etc. The pattern here is add 2, add 3, add 4, add 5, etc.

1. Let the nth term be a_n. The recursive equation can be written as a_n = a_(n-1) + n where a_1 = 1 (Use this because they most likely teach you this in schools)

Here is it written in an arithmetic equation (most likely not taught in school):

We can write an arithmetic expression using the summation formula because it is basically the sum of the numbers from 1 to n, so a_n = n(n+1)/2

2. Using the recursive, we would need to constantly add until you get up to a_21, which would take a while. Using the arithmetic equation, we can simply get:

21(21+1)/2 = 21(11) = 231

The mixed fraction number 2 ⁷/₈ is greater than the mixed fraction number 2 ¹/₂.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The mixed fraction numbers are given below.

2 ⁷/₈ and 2 ¹/₂

Convert the mixed fraction number into a decimal number. Then we have

2 ⁷/₈ = 2 + 7/8 = 2 + 0.875 = 2.875

2 ¹/₂ = 2 + 1/2 = 2 + 0.50 = 2.50

The mixed fraction number 2 ⁷/₈ is greater than the mixed fraction number 2 ¹/₂.

The part of the expression representing the amount of tax to be paid is;

0.08(507)

Step-by-step explanation:

Here, we want to select the part of the expression that represents the amount of tax Deborah has to pay

From the expression, we have ;

0.08(507) + 50h

Kindly note that we can have 0.08 as 8/100

8/100 is same as 8%

when we represent taxes, it is usually a percentage of something

In that case, the tax part would be ; 0.08(507)
