Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $7,000

Interest rate (i)= 2.5%

To calculate the future value after x years, we need to use the following formula:

FV= PV*(1 + i)^x

Now, for 9 years:

x= 9

FV= 7,000*(1.025^9)

FV=$8,742.04

Daniella is making 2/3 of a recipe. the full recipe calls for 3 1/2 cups of flour. how many cups of flour should Danielle use?

kupik [55]

2 $\frac{1}{3}$ cups of flour

We require to find $\frac{2}{3}$ of 3 $\frac{1}{2}$

change the mixed number to an improper fraction and of to multiply

3 $\frac{1}{2}$ = $\frac{7}{2}$

$\frac{2}{3}$ × $\frac{7}{2}$

= $\frac{2(7)}{3(2)}$ = $\frac{14}{6}$ = $\frac{7}{3}$ = 2 $\frac{1}{3}$

If the graph of the function g defined by g(x)=-2x^2-8 is translated vertically upward by 6 units it becomes the graph of a func

$\bf \qquad \qquad \qquad \qquad \textit{function transformations}

\begin{array}{rllll} 
% left side templates
f(x)=&{{ A}}({{ B}}x+{{ C}})+{{ D}}

if it shifts up vertically by 6 units, well, then just add 6 to D
