Answer:

Initial Velocity= 49 m/s

Time period= 5 secs

Explanation:

THIS IS THE COMPLETE QUESTION BELOW

A rocket shoots up 123 meters. What is it initial velocity?How long is it ascending

The initial velocity can be calculated using the expression below

u= √( 2gh)

Where g= Acceleration due to gravity= 98 m/s^2

h= height

Substitute the values we have

u = √(2*9.8*123)

u=√( 2410.8)

u = 49 m/s

the time period can be calculated as

(49/9.8)

= 5 sec

Hence time period is 5 secs

The Bureau of Labor Statistics reported the CPI stood at 215.9 in December 2009, while one year earlier it was 210.2. Suppose Ja

makvit [3.9K]

Answer:

Annual rate of inflation = [(215.9 - 210.2) / 210.2] * 100

Annual rate of inflation = 2.7%

Real income change = Nominal income change - inflation rate

Janice Real income change = 4% – 2.7%

Janice Real income change = 1.3%

This means Janice's real income did increase by 1.3%.

Jeff Real income change = 2% – 2.7%

Jeff Real income change = -0.7%

This means Jeff's real income did decrease by 0.7%.

The turnout for a game is expected to reach 70,000 fans, of which 60 percent are expected to drive. An Average of 2 fans come in

GenaCL600 [577]

Answer: Eight satellite lots will be needed to accomodate all the vehicles.

Expected turnout for the game 70,000 fans

Proportion of people expected to drive 60%

Number of people expected to arrive by car: $70000*0.6 = 42,000$

Number of people per vehicle 2

Expected number of cars $\frac{42000}{2} = 21000$

Number of car parks in the stadium 9000

Number of additional car parks required $21,000-9,000 = 12,000$

Number of car parking per satellite lot 1500

Number of satellite lots required $\frac{12000}{1500}= 8$

irga5000 [103]

<span>The pizza is a neutral good. A neutral good is a good whose demand is not changed even though the income provided by the good is changed. A person's income can go either up or down, but their desire to buy more or less of Jamal's pizza will not change, so pizza sales will not go up or down. Demand and income are not tied to each other.</span>

Consider a market characterized by the following inverse demand and supply functions: P X = 10 - 2Q X and P X = 2 + 2Q X. Comput

lyudmila [28]

Answer:

Consumers surplus = $4

Producers surplus = $4

Explanation:

Quantity demanded = Quantity supplied (when there is equilibrium).

Given:

Demand function: PX = 10 -2Q

Supply function: PX = 2 + 2Q

We first solve the equation:

10 - 2Q = 2 + 2Q

Bringing like terms, we have:

2Q + 2Q = 10 -2

4Q = 8

Q = 2

Substituting 2 for Q in the demand function, we have:

P = 10 - (2 x 2) =

= 10 - 4 = 6

(When Q=2, P will be 6)

Therefore, from the demand function, when Q = 0, P = 10

Therefore, consumer's surplus will be:

CS = (1/2) x ($10 - $6) x 2 =

=(1/2) x 4 x 2 = $4

From supply function, When Q = 0, P = 2 (Minimum acceptable price)

Therefore, producer's surplus will be:

PS = (1/2) x ($6 - $2) x 2

= (1/2) x 4 x 2 = $4

A marketing report concerning personal computers states that 650,000 owners will buy a printer for their machines next year and

drek231 [11]

Answer:

450,000 will buy both a printer and at least one software package

Explanation:

A (size 650,000) is the set of printer buyers

B (size 1,250,000) is the set of software buyers

(A or B) (size 1,450,000) is the set of people buying either a printer or software package.

(A and B) is the set of people buying both a printer and at least one software package

According to the inclusion–exclusion principle in set theory, we have:

(A or B) = A + B - (A and B)

So (A and B) = A + B - (A or B) = 1,250,000 + 650,000 - 1,450,000 = 450,000
