Dima020 [189]

Answer:

9.3%

Step-by-step explanation:

Given data

Principal=$11200

Futute value= $14345

Time= 3years

The simple interest expression is given as

A=P(1+rt)

substitute

14345=11200 (1+r*3)

14345=11200+r33600

14345-11200=r33600

3145=r33600

r= 3145/33600

r=0.093

Hence the rate is 9.3%

Answer:

opening the brackets we have;

3t+15+5t+15=-4t-12

collect like terms

3t+5t+15+15=-4t-12

8t+30=-4t-12

8t-4t=-12+30

4t=18

t=18/4

Answer:

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

Step-by-step explanation:

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