The expression 1.08s + 1.02b1.08s+1.02b predicts the end-of-year value of a financial portfolio where ss is the value of stocks

Marysya12 [62]

Answer:

$22350 is the predicted value of portfolio.

Step-by-step explanation:

The given expression is 1.08s + 1.02b1.08s + 1.02b which predicts the end of year value of a financial portfolio.Here s = value of stocks and b = value of bonds.

Now we have to calculate the value of a portfolio with s = $200 and b = $100

So we will put the values of s and b in the given expression to calculate the value portfolio.

1.08×200 +1.02×(100)×1.08×(200)+ 1.02×(100) = 216 + 22032 + 102

= $22350

The predicted end to end year value of portfolio is = $22350

The kinetic energy (in joules) of a moving object can be calculated from the expression 1/2mv^2, where m is the mass of the obje

algol13

Answer: $116\text{ joules}$

Step-by-step explanation:

Given: Mass of baseball=0.145 kg

Speed of baseball=40 meters per second

Also it is given that The kinetic energy (in joules) of a moving object can be calculated from the expression $\frac{1}{2}mv^2$ , where 'm' is the mass of the object in kilograms and 'v' is its speed in meters per second.
