Answer:
1. 3 is a constant term of the expression.
2. 9 is constant term of the expression.
3.7 is a constant term of the expression.
Step-by-step explanation:
1. 3+c+e
Here 3 is a constant term of the expression.
c and e are the variables.
The coefficient of c is 1.
The coefficient of e is 1.
It is a trinomial expression.
2.
5m +9
9 is constant term of the expression.
m is a variable of the expression.
The coefficient of m is 5.
It is a binomial expression.
3.
3p²+7
7 is a constant term of the expression.
p is the variable.
The coefficient of p² is 3.
It is a binomial expression.
One – hundredth is fraction that can
also be written in decimal form. The fraction form is 1/00, while the decimal
form is 0.01. so the description of the one hundredth of 36 can be solved by multiplying
it by 0.01

Answer:
2 days
Step-by-step explanation:
Use the given formula
y = 5x + 4
The information:
y is the money spent
x is the number of days
It is known that Justin spent $18
so now just substitute in that value
$18 = 5x + 4
and simplfiy by inverse operations
18 = 5x + 4
-4 -4
14 = 5x
/5 /5
2.8 = x
As per this problem, one can infer that renting a game is done by days, and will be charged in days, hence renting a game for 0.8 days is pointless
meaning that the final answer is 2 full days
Answer:
<em>(a) 40 milligrams</em>
<em>(b) 1.21 milligrams</em>
Step-by-step explanation:
<u>Exponential Function</u>
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.
(a) The initial amount injected to the patient can be found when h=0
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
