= a^2+b^2
There are no like terms. Therefore it stays the same.
You multiply and 1,280 and you turn it into a decimal so your answer would be 13.0
Answer:
Step-by-step explanation:
Each year, he gets a 3% raise. It means that her salary in increasing in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of term in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
a = $35000
r = 3 + 3/100 = 1.03
Therefore, the expression that gives the total amount Alex has earned in his first n years of his career, Sn is
Sn = (35000(1.03^(n) - 1)/1.03 - 1
Sn = (35000(1.03^(n) - 1)/0.03
Answer:
(a) 1408366
(b) 448524
Step-by-step explanation:
Pressure on a vertical surface by a static non-viscous fluid is =Pressure at center of mass of the surface *Area of surface covered by fluid.
A) acceleration due to gravity =9.8*3.38
Radius =6
So pressure at center of circular plate =density*g*R
Total force =density*g*R*Area = 1408366
B) Here center of mass of semicircle sector is at from center.
So pressure at center of mass of semicircle =*density*9.8*3.38
Net force =*density*9.8*3.38*Area of semicircle =448524
