Solve for Vf

Multiply both sides by t.

at= Vf - Vi

Add Vi

at+Vi= Vf

Then substitute the correct numbers based on the variables

(2ft/s^2)(3 s) + 4 ft/s^2= 10

uppose that Mary's utility function is U(W) = W0.5, where W is wealth. She has an initial wealth of $100. How much of a risk

Stels [109]

Note that $U(W) = W^{0.5}$

Answer:

Mary's risk premium is $0.9375

Step-by-step explanation:

Mary's utility function, $U(W) = W^{0.5}$

Mary's initial wealth = $100

The gamble has a 50% probability of raising her wealth to $115 and a 50% probability of lowering it to $77

Expected wealth of Mary, $E_w$

$E_{w}$ = (0.5 * $115) + (0.5 * $77)

$E_{w}$ = 57.5 + 38.5

$E_{w}$ = $96

The expected value of Mary's wealth is $96

Calculate the expected utility (EU) of Mary:-

$E_u = [0.5 * U(115)] + [0.5 * U(77)]\\E_u = [0.5 * 115^{0.5}] + [0.5 * 77^{0.5}]\\E_u = 5.36 + 4.39\\E_u = \$ 9.75$

The expected utility of Mary is $9.75

Mary will be willing to pay an amount P as risk premium to avoid taking the risk, where

U(EW - P) is equal to Mary's expected utility from the risky gamble.

U(EW - P) = EU

U(94 - P) = 9.63

Square root (94 - P) = 9.63

If Mary's risk premium is P, the expected utility will be given by the formula:

$E_{u} = U(E_{w} - P)\\E_{u} = U(96 - P)\\E_u = (96 - P)^{0.5}\\(E_u)^2 = 96 - P\\ 9.75^2 = 96 - P\\95.0625 = 96 - P\\P = 96 - 95.0625\\P = 0.9375$

Mary's risk premium is $0.9375

Give the zeros (if any) of the quadratic function f(x)=3(x-4)(x+11).

maxonik [38]

Set each of the binomials equal to zero and solve for x. The two values will be the zeros of the equation:
(x-4) = 0 (x+11) = 0

x-4 = 0 x + 11 = 0
x = 4 x = -11

The zeros of the equation are -11 and 4

How to do number 6! Anyone I will cash app you

olganol [36]

Answer:

Shawna has 50, 48,46,44 or 42 yellow pencils.

Step-by-step explanation:

Here, given the total number of pencils Shawna has = 55 pencils

So, The number of YELLOW PENCIL + BLUE PENCIL = 55

or, Y + B = 55

Now let us take the given cases of blue pencils one by one:

1. If she has 5 blue pencils

Here, B = 5

So, as Y + B = 55 ⇒ Y + 5 = 55

or, Y = 5 5 - 5 = 50

Hence, Shawna has 50 yellow pencils.

2. If she has 7 blue pencils

Here, B = 7

So, as Y + B = 55 ⇒ Y + 7 = 55

or, Y = 5 5 - 7 = 48

Hence, Shawna has 48 yellow pencils.

3. If she has 9 blue pencils

Here, B = 9

So, as Y + B = 55 ⇒ Y + 9 = 55 ⇒ Y = 55- 9 = 46

Hence, Shawna has 46 yellow pencils.

4. If she has 11 blue pencils

Here, B = 11

So, as Y + B = 55 ⇒ Y + 11 = 55 ⇒ Y = 55- 11 = 44

Hence, Shawna has 44 yellow pencils.

5. If she has 13 blue pencils

Here, B = 13

So, as Y + B = 55 ⇒ Y + 13 = 55 ⇒ Y = 55- 13 = 42

Hence, Shawna has 42 yellow pencils.
