An acorn falls from the branch of a tree to the ground 25 feet below. The distance, S, that the acorn is from the ground as it falls is represented by the equation S(t) = –16t2 + 25, where t is the number of seconds. For which interval of time is the acorn moving through the air?

Answers

The end of its travel is when S(t)=0 or when it has hit the ground...

-16t^2+25=0  divide equation by -1

16t^2-25, this is a difference of squares which always factors:

(a^2+b^2)=(a+b)(a-b), in this case:

(4t+5)(4t-5)=0, since t>0

t=5/4=1.25, and since it started falling at t=0, its time moving in the air is:

1.25-0=1.25 seconds.

Answer: B or 0 < t < 5/4

Pentagon RSTUV is circumscribed about a circle. What is the value of x if RS = 6, ST = 9, TU = 7, UV = 15, and VR = 14?

Answers

Starting at vertex V going until vertex S, we make our calculations.

VR = 14

Rx = x

therefore, xS = VR – Rx

xS = 14 – x                           ---> 1

 

Now starting at vertex V going left to vertex S, we make our next set of calculations. Assuming x is on VR but nearer R

VR  = 14 - x

at UV = 15 – (14 – x)

at UV = 1 + x

at TU = 7 – (1 + x)

at TU = 6 – x

at ST = 9 – (6 – x)

at ST = 3 + x                        ---> 2


Equate 1 and 2:

14 – x = 3 + x

2 x = 11

x = 5.5

To find the value of x in the circumscribed pentagon RSTUV with given sides, we set up an equation based on the sum of the lengths of the opposite sides. After solving the equation, we determined that x is 25.

Pentagon RSTUV and the Value of x

Given that pentagon RSTUV is circumscribed about a circle, we need to find the value of x,

where RS = 6, ST = 9, TU = 7, UV = 15, and VR = 14.

For a polygon circumscribed about a circle, the sum of the lengths of the pairs of opposite sides must be equal. Therefore, we can set up the equation:

RS + TU + x = ST + UV + VR

Substituting the given values:

6 + 7 + x = 9 + 15 + 14

Simplifying the right-hand side:

6 + 7 + x = 3813 + x = 38x = 38 - 13x = 25

Thus, the value of x is 25.

A company wants to save for a new piece of equipment that will cost 17,500. They have 15,000 to invest today in an account that earns 4.75% annual simple interest. How long must they invest the money in order to purchase the new equipment? Round to the tenth

Answers

The additional amount of $ needed is $17,500-$15,000, or $2,500.  This is the necessary increase to the $15,000 principal.

So this question boils down to how long it will take for the original $15,000 to earn $2,500 at 4.75% annual simple interest.

We thus must solve the following for n, the # of years:

i = p r t

$2,500 = $15,000 (0.0475) n

Solving for n (the number of years), n = $2,500 / [$15,000*0.0475]

Please finish this arithmetic.  Note that n is measured in years, so include "years" as part of your final answer.

A person in a casino decides to play blackjack until he loses a game, but he will not play more than 3 games. let l denote a loss and w denote a win. what is the sample space for this random experiment

Answers

Final answer:

The sample space for the random experiment of playing blackjack until a loss or a maximum of three games are played is represented by the set {l, wl, ww}.

Explanation:

The sample space for this scenario comprises of all possible outcomes of playing "blackjack" until the person loses or has played three games. We represent win and loss by w and l respectively. By these definitions, we get the following possibilities: l (losing on the first game), wl (winning the first game then losing the second), and ww (winning the first two games and decide not to play a third game or it wasn't possible to play a third game). This assumes that the player stops after either losing a game or after playing the third game, even if he won that.

Note that the scenario where the player wins all three games (www) is not included in the sample space because the problem states that the player will stop playing as soon as they lose a game.

Mitch planted cabbage,squash and carrots on his 150 acre-farm. He planted half the farm with squash and 22% with carrots. How many acres did he plant with cabbagge?

Answers

150 total acres...
he planted half the farm with squash.....150/2 = 75 acres squash
he planted 22% with carrots...0.22(150) = 33 acres carrots

150 - (75 + 33) = 150 - 108 = 42 acres cabbage <==

Answer:

42 acres

Step-by-step explanation:

Mitch planted cabbage,squash and carrots on his 150 acre-farm.

He planted half the farm with squash. The acres planted with squash are:

1/2 × 150 acre = 75 acre

He planted 22% with carrots. The acres planted with carrots are:

22% × 150 acre = 33 acre

The sum of the acres planted with cabbage, squash and carrots is equal to the total number of acres.

cabbage + squash + carrots = 150 acre

cabbage = 150 acre - squash - carrots

cabbage = 150 acre - 75 acre - 33 acre = 42 acre

Assume you have an infinite supply of these candy pieces from which to draw. if you draw two pieces one right after the​ other, are the events of getting a greena green on the first and a greena green on the second​ disjoint, independent, or​ neither?

Answers

First let us define what probability is. Probability is the measure of chance on getting a success or successful event out of all the total possible events. This can be expressed mathematically as:

Probability = Number of successful events / Total events

Which in this case can be written as:

Probability = Number of green candies / Total candies

So if we draw 1 candy in the 1st trial, therefore the value of the numerator and denominator would vary in the 2nd trial (since there is reduction of green candy & total candy). However the problem specifically states that there is an INFINITE supply of candies. Which means that the value do not change in the next trial.

Therefore the probability in the 2nd trial is not affected by the event of the 1st trial. So they are independent events. They cannot be disjoint since they are not mutually exclusive, both can occur at the same time (green and green).

Independent

Write and solve an equation to answer the question.

What number a is 24% of 25?

Answers

a = .42 x 25 = 6

the number 6 is 24% 0f 25.

Just write 24% as a decimal .24 or 0.24


Final answer:

To find the number that is 24% of 25, you multiply 0.24 by 25, which equals 6.

Explanation:

To find what number a is 24% of 25, we can set up an equation using the concept that a percent is a way of expressing a fractional amount of something.

We know that 24% means 24 out of 100, which can be written as the fraction 24/100 or 0.24 in decimal form.

To translate the question into an equation, we write:

a = 0.24 × 25

Next, we calculate the value of a by multiplying 0.24 (the decimal form of 24%) by 25. This gives us:

a = 6

Therefore, the number a, i.e., 24% of 25 is 6.

To determine whether the pipe welds in a nuclear power plant meet specifications, a random sample of welds is selected, and tests are conducted on each weld in the sample. weld strength is measured as the force required to break the weld. suppose the specifications state

Transmutation is the process of changing the substance, tangible or not, from one form to the other. It means the transformation of one element in the periodic table into another by one or a series of nuclear decays or reactions. One type of transmutation is nuclear transmutation. Nuclear transmutation is the conversion of one chemical element or isotope into another though nuclear reactions or nuclear decay. Second type of transmutation is artificial transmutation. Artificial transmutation occur in machinery that uses nough energy to cause changes in the nuclear structure of the elements.

Engineers test the weld strength of pipe welds in nuclear power plants to ensure they meet safety specifications. Tensile strength and pressure tolerance are key factors tested to maintain plant safety and functionality. Regulatory standards, like those from the NRC, guide acceptable performance levels for power plant components.

To ensure the safety and functionality of the nuclear power plant's infrastructure, engineers conduct tests on components such as pipe welds. These tests involve assessing weld strength, which is the force required to break a weld, and must meet specific specifications for the plant to operate safely. If not, the structural integrity of the power plant could be compromised, potentially leading to failures in electrical generation or even safety hazards.

The tensile strength of a material is a critical factor in this scenario. It is defined as the force per unit area (measured in Newtons per square meter or Pascals) needed to cause failure of the material by pulling it apart. This strength needs to be tested to prevent issues like the SS Schenectady ship's cracking under stress, which can have catastrophic consequences.

Regulatory standards, such as those set by the Nuclear Regulatory Commission (NRC), often determine the acceptable levels of component performance, including valves and tubing, within a power plant. These standards may change over time in response to new findings or incidents, reflecting the evolving understanding of material properties and failure risks under operational conditions.

In statistical terms, such tests might involve a hypothesis test to determine if the pressure tolerances of two valve types differ significantly, or if the structural components meet the required strength, safety, and operational standards.

Answers

 

Since pi is equivalent to 3.14 and means 180°, therefore 1.75 which is about half of pi should be at almost 90°. The cos of a 90° angle which is located on the y axis should be zero, therefore cos 1.75 must be near zero. However in this case it is near one, clearly his calculator is in degree mode that is why he got an erroneous answer.

What Sam can do to get the correct answer would be to convert his calculator into radian mode or convert the given 1.75 rad into degrees:

θ = 1.75 rad (180° / π rad)

θ = 100.2676

cos 100.2676 = -0.1782   which is now correct since it is nearer to zero
