It is just asking to find the sum of interior angles
So follow this rule 180(n-2)
180(5-2)
180(3)= 540
So in another words: a+b+c+d+e=540
a function that model the number of people that receives email in week t is
.
<u>Step-by-step explanation:</u>
Here we have , Tobias sent a chain letter to his friends . The number of people who receives the email increases by a factor of 4 in every 9.1 weeks , and can be modeled by a function P, which depends on the amount of time t weeks . Tobias initially sent letter to 37 friends . We need to write a function that model the number of people that receives email in week t . Let's find out:
Basically it's an exponential function as
, In question initial value is 37 & and for every 9.1 weeks there is increase in people by a factor of 4 i.e.
⇒ 
But , wait ! People increase in every 9.1 weeks not every week so modified equation will be :
⇒
Therefore , a function that model the number of people that receives email in week t is
.
Answer:
Some real numbers are integer
Step-by-step explanation:
Real numbers ;
- Natural numbers (counting numbers) = Integer
- Whole numbers = Integers
- Integers =Integers
- Rational numbers (fractions , repeating or terminating decimals) = Fraction and decimal are not integers
- Irrational numbers. = Not integer
Sin x =cos 19
X =sin^1(cos 19)
X=71
The similarity relationship is AC / EC = AB / ED.
The length of AB is 157.50m.
<h3>What is the length of AB?</h3>
When two triangles are similar, the ratio of the known sides of the triangles can be used to determine the length of the side of the unknown length.
The similarity relationship is : AC / EC = AB / ED
AC = 160 + 50 = 210
210 / 160 = AB / 120
AB = (210 X 120) / 160 = 157.50
