Which type of grapefruit cost more per pound?

pochemuha

Answer:

(a) 40 milligrams

(b) 1.21 milligrams

Step-by-step explanation:

Exponential Function

It's commonly used to model real situations in life, like this one proposed in the question where the number of milligrams of a drug D(h) in a patient's bloodstream h hours after the drug is injected is modeled by the following function.

$D(h) =40e^{-0.5h}$

(a) The initial amount injected to the patient can be found when h=0

$D(0) =40e^{-0.5(0)}=40e^{0}=40$

Initial amount: 40 milligrams

(b) Let's plug h=7

D(7) =40e^{-0.5(7)}=40e^{-3.5}=1.21

The amount in the bloodstream after 7 hours is 1.21 milligrams

You deposit 700$ in an account with an annual internet rate of 4% after 5 years

alex41 [277]

Answer:

840

Step-by-step explanation:

Heres the easiest way to figure this out. You deposit $700 dollars into your account, correct? So, the annual interest rate is 4%. Take 700 dollars and multiply that by 4 percent. You get $28. So, EVERY. SINGLE. YEAR. you get 28$. So, multiply 28 by 5. Thats $140. Then, add 140 into 700, and you get 840.

Hope this helped!

Please help me with number five WHOEVER EXPLAINS AND GIVES ME THE ANSWER GETS BRAINLEST

MrMuchimi

You are correct. The answer is C, 11 units
The ordered pairs are (3,6) and (14,6)
The x numbers are the same. The y numbers are different.
So, you would subtract 3 from 14 (14-3) to get the answer of 11 units.

Hope this helps you! (:

milo is talking to his sister lisa about factors. he said he thinks that any even number always has more factors than any odd nu

UkoKoshka [18]

Answer:

I agree with Lisa

Step-by-step explanation:

* Lets explain the meaning of the factors of a number

- Factors are the numbers you multiply to get another number

- Ex: factors of 12 are 1 , 2 , 3 , 4 , 6 , 12 because

1 × 12 = 12 , 2 × 6 = 12 , 3 × 4 = 12

- 1 is a factor every number

- The number is a factor of itself

* Lets solve the problem

- Milo said he thinks that any even number always has more

factors than any odd number

- Lisa said she doesn't agree with him

* Lets take some examples for even and odd number to prove who

is right

- We will chose numbers between 1 and 22

# Even numbers: 2 , 4 , 14 , 18

# Odd numbers: 3 , 9 , 15 , 21

∵ The factors of 2 are 1 , 2

∴ 2 has 2 factors

∵ The factors of 4 are 1 , 2 , 4

∴ 4 has 3 factors

∵ The factors of 14 are 1 , 2 , 7 , 14

∴ 14 has 4 factors

∵ The factors of 18 are 1 , 2 , 3 , 6 , 9 , 18

∴ 18 has 6 factors

∵ The factors of 3 are 1 and 3

∴ 3 has 2 factors

∵ The factors of 9 are 1 , 3 , 9

∴ 9 has 3 factors

∵ The factors of 15 are 1 , 3 , 5 , 15

∴ 15 has 4 factors

∵ The factors of 21 are 1 , 3 , 7 , 21

∴ 21 has 4 factors

∵ The number of the factors of the even numbers are 2 , 3 , 4 , 6

∵ The number of the factors of the odd numbers are 2 , 3 , 4

∴ The Factors of even numbers and odd numbers are equal

like 2 and 3 , 4 and 9 , 14 and 15

OR

The factors of even number greater than the factors of the odd

number like 18 the number of the factors of 18 is greater than the

number of the factors of all odd numbers above

∴ Not always that any even number has more factors than any odd

number

∴ I agree with Lisa
