Answer is 19;
Problem
a1=325 , d=25 , S19=?
Result
S19=10450
Explanation
To find S19 we use formula
Sn=n2⋅(2a1+(n−1)⋅d)
In this example we have a1=325 , d=25 , n=19. After substituting these values into the above equation, we obtain:
Sn19=n2⋅(2a1+(n−1)⋅d)=192⋅(2⋅325+(19−1)⋅25)=192⋅(650+18⋅25)=192⋅(650+450)=192⋅1100=10450
Answer:
f(5)=1/22
Step-by-step explanation:
f(5)=-2/-5(5)-19
f(5)=-2/-25-19
f(5)=-2/-44
f(5)=1/22

Answer: True</h3>
Explanation:
The area of the circle with radius 10 is...
A = pi*r^2
A = pi*10^2
A = 100pi
The surface area of the sphere with radius 5 is...
SA = 4pi*r^2
SA = 4pi*5^2
SA = 100pi
Both results are the same, so the claim is true. We can think of surface area as the amount of wrapping paper needed to cover the sphere.
Yes because "If i'm hungry, then I'm not happy" but "if I'm not hungry, then I'm happy"
Being hungry is bad, so I'm not happy
BUT
being not hungry is good, so I'm happy
