B.All real numbers
C.All positive numbers
D.All integers

Answers

Answer 1

Answer: c(t)

In a function the domain is all the values of t while the range is all the values of c(t).

Since t represents time in minutes, most appropriate domain for c(t) is A. Positive integers only.

Find the first,fourth, and eighth terms of the sequence. A(n)=-5*2^n-1

Answers

Answer: $A(1)=-5$

$A(4)=-40$

$A(8)=-640$

Step-by-step explanation:

Given sequence : $A(n)=-5*2^(n-1)$

To find the first term, we need to put n=1 in the above sequence , we get

$A(1)=-5*2^(1-1)=-5*2^0=-5$

To find the fourth term, we need to put n=4, we get

$A(4)=-5*2^(4-1)=-5*2^3=-5*8=-40$

To find the eighth term, we need to put n=8, we get

$A(8)=-5*2^(8-1)=-5*2^7=-5*128=-640$

Answer:

$A(1)=-5*2^1-1=-11$

$A(1)=-5*2^4-1=-81$

$A(1)=-5*2^8-1=-1281$

Step-by-step explanation:

Given : $A(n)=-5*2^n-1$

To find : $A(1), A(4), A(18)$

Solution:

Put n=1, $A(1)=-5*2^1-1$

$A(1)=-10-1=-11$

Put n=4, $A(1)=-5*2^4-1$

$A(1)=-80-1=-81$

Put n=8, $A(1)=-5*2^8-1=$

$A(1)=-1280-1=-1281$

what is the approximate volume of a tree trunk if the trunk is 13 feet tall with a circumference of 4.5 feet

Answers

Answer:

V=21.17³

Step-by-step explanation:

c=2πr

4.5=2(3.14)r

4.5/6.28=6.28r

6.28s cancel each other out

7.16=r

round

V=πr²h

V=21.17³

Volume of a cylinder is $\pi r^(2) h$
C = $\pi 2r$
4.5/2 $\pi$ = r
0.7162 = r
$\pi r^(2) 13$ = 20.91

Maya is choosing between several pay plans for her new job. If she usually has monthly sales of about $5,000, which plan would allow Maya to earn the most money in a month?Plan
Monthly base salary
Commission rate
A
$500
8%
B
$600
7%
C
$700
6%
D
$800
5%
A. plan A
B. plan B
C. plan C
D. plan D

Answers

Plan D will allow Maya to earn the most money in a month. Since the total salary is the sum of the basic salary and the commissionrate.

Given data:

It is given that,

Maya usually has monthly sales of about $5000

The plan is given with a monthly base salary and commission rate

Calculating for the best plan:

Option (A):

base salary = $500

commission rate = 8%

Total salary = basic salary + commission rate

= 500 + 5000 × 8%

= 500 + 400

= 900

Option (B):

base salary = $600

commission rate = 7%

Total salary = basic salary + commission rate

= 600 + 5000 × 7%

= 600 + 350

= 950

Option (C):

base salary = $700

commission rate = 6%

Total salary = basic salary + commission rate

= 700 + 5000 × 6%

= 700 + 300

= 1000

Option (D):

base salary = $800

commission rate = 5%

Total salary = basic salary + commission rate

= 800 + 5000 × 8%

= 800 + 250

= 1050

Therefore, plan (D) allows Maya to earn the most money in a month.

A pound of popcorn is popped for a class party. The popped corn is put into small popcorn boxes that each hold 120 popped kernels. There are 1,600 kernels in a pound of unpopped popcorn. If all the boxes are filled except for the last box, how many boxes are needed and how many popped kernels are in the last partially filled box?

Answers

In the last partially filled box the number of popped kernels is 36.

What is an expression?

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the popped corn is put into small popcorn boxes that each hold 120 popped kernels. There are 1,600 kernels in a pound of unpopped popcorn. All the boxes are filled except for the last box,

The number of the popped Kernels will be calculated as below:-

Divide 1600 Kernels by 120 propped Kernels:-

1600 / 120 = 13.3

Multiply 120 by 30 percent.

120 x 0.3 = 36

Therefore, in the last partially filled box the number of popped kernels is 36.

1600 / 120 = 13.3
You will need 14 boxes.

120 x 0.3 = 36
There were 36 kernels in the partially filled box.
