Answer:
the answer is C. (7 – 3) hope that helps : )
Answer:
4.891
its side b (opposite side of the 50 degree angle)
Step-by-step explanation:
side c = 6
angle A is 20 side a (opposite side) = 2.184
angle B is 50 side b (opposite side) = 4.891
angle C is 110 side c (opposite side) = 6
1.
get third angle
50 + 20 = 70
180 - 70 = 110
third angle C is 110
2.
get side a
sin A/a = sin C/c
a/c = sinA/sinC
a = c * sinA/sinC
a = 6 * (sin20/sin110)
get sin in degrees
a = 6 * (.342/.9397)
a = 2.184
7 14/18 since you can reduce this to 7 7/9:)
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
.
