Answer:
$29.92
Step-by-step explanation:
Step one:
given data
The bill for dinner totaled $74.80
Then the tip is 20%
Required
The amount paid by each person after the tip was added to the cost of the dinner
Step two:'
the amount of the tip is
=20/100*74.80
= 0.2*74.80
=$14.96
The total is 14.96+74.80
=$89.76
The number of persons including the celebrant is = 3
so each person will pay
=89.76/3
=$29.92
Answer:
(-2,0) and (0,1)
I could be way off
Step-by-step explanation:
Answer:
slope = -3
Step-by-step explanation:
slope is: (delta y)/(delta x)
so slope = (15-3)/(0-4)
= -3
a_3 is 45 and a_10 is 98415
Step-by-step explanation:
Given
a_1 = 5
a_2 = 15
First of all we have to calculate the common ratio of the sequence. The common ratio is the ratio between two consecutive terms of a geometric sequence.
So,
The explicit formula for geometric sequence is:
Putting the value of r and a_1
Putting n=3 in the explicit formula
Putting n=10 for tenth term
Hence,
a_3 is 45 and a_10 is 98415

Answer:
No
Step-by-step explanation:
Given values are
f(x) = 5x^3+60x^2+109x+90
x = -10.
Given Polynomial is 5x^3+60x^2+109x+90 .
= (90)+(5.x^3)+(60.x^2)+(109.x)
By putting x = (-10) we can rewrite it as
= (90)+(5.(-10)^3)+(60.(-10)^2)+(109.(-10))
= (90)+(-5000)+(6000)+(-1090)
= 0
The remainder of given polynomial is 0.
