Ierofanga [76]

Answer:

1498.17

Step-by-step explanation:

formula A = P(1 + \frac{r}{100}  )^{n} where r is the rate of interest compounded and n is the number of times compounded.

r = 4.5 / 12 = 0.375 since it is compounded monthly thus need to divide by 12 months

n = 9 x 12 = 108 ( 9 years in months)

A = 1000(1 + \frac{0.375}{100})^{108} = 1498.167

Dimas [21]

Answer:

\large\boxed{(f+g)(x)=2x^2+\dfrac{1}{2}x+4\dfrac{1}{3}}

Step-by-step explanation:

(f+g)(x)=f(x)+g(x)\\\\\text{We have}\\\\f(x)=\dfrac{1}{3}-\dfrac{1}{2}x,\ g(x)=2x^2+x+4.\\\\\text{Substitute:}\\\\(f+g)(x)=\left(\dfrac{1}{3}-\dfrac{1}{2}x\right)+(2x^2+x+4)\\\\=\dfrac{1}{3}-\dfrac{1}{2}x+2x^2+x+4\qquad\text{combine like terms}\\\\=2x^2+\left(-\dfrac{1}{2}x+x\right)+\left(\dfrac{1}{3}+4\right)\\\\=2x^2+\dfrac{1}{2}x+4\dfrac{1}{3}

Which equation represents the hyperbola that has its focus farthest from its center?
postnew [5]
The distance the focus is from its center is noted as 'c' .

where  c^2 = a^2 + b^2.

Therefore whichever hyperbola has the largest ' a^2 +b^2 ' will have the largest 'c' value.

A)  8^2 + 7^2 = 113

B)  (19/2)^2 + (11/2)^2 = 120.5

C)  6^2 + 9^2  = 117
 
D) 5^2 + (19/2)^2 = 115.25

Answer is B
