The national interest rate on houses for 25 years is 4.3%. The banker wishes to test that the local interest rates are lower than the national rate. So he should use the initial data of 4.3% interest as his base data. Then he should investigate the rates of houses in the local vicinities and compare it to his base data.

Answer:
x = 13
Step-by-step explanation:
No se exactamente como decir esto porque yo ayudo la majoria de los usuario en ingles pero hay que usar un método para describir a x
Un método que se llama Pythagorean theorem
Pythagorean theorem: a^2 + b^2 = c^2 donde a^2 = 5 b^2 = 12 y c^2 = x
Entonces…
5^2 + 12^2 = c^2
Nota: podemos ver que esto esta bien porque el sum de los dos lados suma el mas largo.
Ahora
25 + 144 = c^2
c^2 = 169
Pero eso no puede ser la respuesta porque no tiene sentido a que x sea un lado que mide 169 entonces tenemos que usar sqrt rt
sqrt rt de 169 = 13
x = 13
Answer:
= 8
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Here a = 8 and r = - 24 ÷ 8 = - 3, thus
= 8
