Final answer:

The stone is approximately 583 feet high 4 seconds later.

Explanation:

To find the height of the stone 4 seconds later, we can use the equation of motion for an object in free fall:

h = h0 + v0t + (1/2)gt^2

Where:

h = height at time t

h0 = initial height

v0 = initial velocity

g = acceleration due to gravity

t = time

Substituting the given values:

h = 775 + 16(4) + (1/2)(-32)(4)^2

h = 775 + 64 - 256

h = 583 feet

Therefore, the stone is approximately 583 feet high 4 seconds later.

Answer:

A

Step-by-step explanation:

Given:

- The original function is:

                               f(x) = x^3

Find:

How does the graph of g(x) = (x − 1)3 + 5 compare to the original function.

Solution:

- We have a general form of the new function relating to parent function.

                               g(x) = a*( x +/- b )^n + c

Where; a, b and c are constants.

- The constant a magnitude denotes steepness of the graph relative to 1 and the sign of a will determine the mirror image of the graph about line y = 0.

- The constant b magnitude denotes shifts of the graph of every x value sign of b will determine the direction of shifts. + b : shift left , - b shift right.

- The constant c magnitude denotes shifts of the graph of every y value. sign of c will determine the direction of shifts. + c : shift up , - b shift down.

- In our g(x).   a = 1 , b = -1 , c = + 5

Hence, g(x) is shifted 1 unit to the right and 5 units up.

The graph of g(x) = (x - 1)^3 + 5 is shifted 1 unit to the right and 5 units up compared to the parent function f(x) = x^3.

The graph of g(x) = (x - 1)3 + 5 is obtained by shifting the graph of f(x) = x3 one unit to the right and five units up. Shifting a function horizontally is done by replacing x with (x - h), where h is the amount of units you want to shift.

In this case, g(x) = (x - 1)3 + 5 is equivalent to f(x - 1) + 5. So the graph is shifted 1 unit to the right. Shifting a function vertically is done by replacing f(x) with f(x) + k, where k is the amount of units you want to shift.

Since f(x - 1) + 5 is obtained by shifting f(x) one unit to the right and five units up, the correct answer is: g(x) is shifted 1 unit to the right and 5 units up.

Answer:

a)[tex]P(X\geq 11) = 0.198[/tex]

b)[tex]P(X\leq 2) = 0.000565[/tex]

c) Mean = 8.8

Step-by-step explanation:

1) Previous concepts

Binomial Distribution is a "discrete probability distribution which is used to calculate the probabilities for the independent trials and for each trial there is only two outcomes success or failure and probability for each success remains constant throughout each trial".

The Binomial distribution is a type of Bernoulli experiment with following properties:

a)There are two possible outcomes; success or failure.

b) Outcomes are independent on preceding result of a trial.

c) The probability of success remains constant throughout the experiment.

d)The number of successes are fixed.

The probability mass function for the Binomial distribution is given by:

[tex]P(X=a)=(nCa)(p)^x (1-p)^{n-x}[/tex]

Where [tex]p[/tex] is the probability of success, n the number of trials and x the number of successes that we want on the n trials.

[tex]X[/tex] represent the number federal inmates that are serving time for drug dealing

[tex]p=0.55[/tex] represent the proportion of federal inmates that are serving time for drug dealing

[tex]n=16[/tex] random sample selected

2) Part a

The random variable X follows this distribution [tex]X \sim Binom(n,p)[/tex]

On this case we want the following probability, and since says greater or equal than 11 we can express like this:

[tex]P(X \geq 11)=P(X=11)+P(x=12)+P(x=13)+P(x=14)+P(x=15)+P(x=16)[/tex]

[tex]P(X=11)=(16C11)(0.55)^{11} (1-0.55)^{5} =0.112[/tex]

[tex]P(X=12)=(16C12)(0.55)^{12} (1-0.55)^{4} =0.0572[/tex]

[tex]P(X=13)=(16C13)(0.55)^{13} (1-0.55)^{3} =0.0215[/tex]

[tex]P(X=14)=(16C14)(0.55)^{14} (1-0.55)^{2} =0.00563[/tex]

[tex]P(X=15)=(16C15)(0.55)^{15} (1-0.55)^{1} =0.000918[/tex]

[tex]P(X=16)=(16C16)(0.55)^{16} (1-0.55)^{0} =0.00007011[/tex]

[tex]P(X \geq 11)=0.112+0.0572+0.0215+0.00563+0.000918+0.00007011=0.198[/tex]

3) Part b

[tex]P(X \leq 2)=P(X=0)+P(x=1)+P(x=2)[/tex]

[tex]P(X=0)=(16C0)(0.55)^{0} (1-0.55)^{16} =0.00000283[/tex]

[tex]P(X=1)=(16C1)(0.55)^{1} (1-0.55)^{15} =0.0000552[/tex]

[tex]P(X=2)=(16C2)(0.55)^{2} (1-0.55)^{14} =0.000507[/tex]

[tex]P(X \leq 2)=0.00000283+0.0000552+0.000507=0.000565[/tex]

4) Part c

The expected value for the binomial distribution is given by the following formula:

[tex] E(X)=np=16*0.55=8.8[/tex]

So then the average number of federal inmates that are serving time for drug dealing on a sample of 16 is approximately 9.

Answer:

Option D.

Step-by-step explanation:

Cost of truck = $16000

Residual value after 5 years = $1000

Depreciated value of a truck in 5 year is

[tex]Depreciation=16000-1000=15000[/tex]

In straight-line method, the value of a fixed asset depreciate by a constant rate.

Since depreciation of truck in 5 years is $15000, therefore, the depression of one year is

1 year Depreciation = [tex]\dfrac{15000}{5}=3000[/tex]

From July 3 to end of fist year = 1/2 year

1/2 year Depreciation = [tex]\dfrac{3000}{5}=1500[/tex]

So, the value at the end of year 1 using straight-line rate is

[tex]Value=16000-1500=14,500[/tex]

Therefore, the correct option is D.

The rate of change of the volume of a ball when the radius is 5cm is -300π cubic centimeters per second.

To find the rate of change of the volume of a ball, we can use the formula for the volume of a sphere, which is V = (4/3)πR³. We are given that the radius is decreasing at a constant rate of 3 cm per second. So, the rate of change of the volume can be found using the derivative of the volume function with respect to time.

First, we differentiate the volume function with respect to time:

dV/dt = (4/3)π×3R²×(-3)

dV/dt = -12πR²

Then we substitute the given value of the radius when it is 5 cm:

dV/dt = -12π×5²

dV/dt = -12π×25

dV/dt = -300π

Therefore, the rate of change of the volume of the ball when the radius is 5 cm is -300π cubic centimeters per second.

Kyle is correct in saying that 3/5 is equal to 60% because 3/5 is equivalent to 60/100.

Kyle says that 3/5 is equal to 60%. This statement can be explained by saying that 3/5 is equivalent to 60/100. To convert a fraction to a percentage, you multiply the top number (numerator) by 100 and then divide by the bottom number (denominator). In this case, multiplying 3 by 100 gives you 300, and when you divide 300 by 5, it equals 60. Hence, 3/5 is indeed equivalent to 60%, which makes Kyle's statement correct.

Answer:

The answer to your question is x = 4

Step-by-step explanation:

                                   2x² - bx - 20 = 0

One root is -2.5

Process

Get the value of the equation when x = -2.5

                                   2(-2.5)² - b(-2.5) - 20 = 0

                                   2(6.25) + 2.5b  - 20 = 0

                                   12.5 + 2.5b - 20 = 0

                                   2.5b = 20 - 12.5

                                   2.5b = 7.5

                                   b = 7.5 / 2.5

                                  b = 3

Then

                                  2x² - 3x - 20 = 0

Factor the polynomial

                                  2 x -20 = -40

                                  2x² -8x + 5x - 20 = 0

                                  2x(x - 4) + 5(x - 4) = 0

                                  (x - 4)(2x + 5) = 0

                                  x₁ - 4 = 0               2x₂ + 5 = 0

                                 x₁ = 4                     x₂ = -5/2

                                                               x₂ = -2.5

Answer:

The "other" or "second" root is 4.

Step-by-step explanation:

We are told that -2.5 is a root of the equation.  The coefficient b of the x term is unknown, and must be determined.  Because -2.5 is a root, synthetic division with -2.5 as divisor must return a remainder of zero.

Setting up synthetic division, we arrive at:

-2.5    /    2    -b    -20

                     -5     +12.5 + 2.5b

          -------------------------------------

                2   -5-b    -7.5 + 2.5b

The remainer, -7.5 + 2.5b, must be zero (0).  Thus, 2.5b = 7.5, and b = 3.

Then the other factor has the coefficients {2, -5-b}, and because b = 3, this comes out to coefficients {2, -8}.

The other factor is 2x - 8, which, if set equal to 0, yields x = 4.  This is the "other root."

Final answer:

The angular speed of the pulley is 120π radians per minute, and the linear speed is 960π inches per minute.

Explanation:

The question pertains to angular and linear speeds related to circular motion. Given that a belt runs a pulley with a radius of 8 inches at 60 revolutions per minute (rpm), we are tasked with finding both the angular speed in radians per minute and the linear speed in inches per minute.

Calculating the Angular Speed

The angular speed (ω) in radians per minute can be calculated using the formula ω = 2π×rpm, where rpm is the number of revolutions per minute and 2π radians is the equivalent of one full revolution.

ω = 2π × 60 = 120π radians/minute

Calculating the Linear Speed

The linear speed (v) can be determined from the radius (r) and angular speed (ω) using the formula v = r×ω. The radius of the pulley is 8 inches, so:

v = 8 inches × 120π radians/minute = 960π inches/minute

lyrics d  - 1.782

Step-by-step explanation:

Assume Normal Distribution

we have  μ₀ = 40       (from Dullco claims)

And from sample   μ  = 37.8    and standard deviation of  5.4

random sample n = 18

We have to use t-student for testing the hypothesis

and we have a one tail test (left) since Dullco claims : " at least"  meaning (always bigger or at least ) not different.

Then

t (s) =( μ -  μ₀) / (σ/√n)   ⇒ t (s) = [(37.8  - 40 )* √18 ]/5.4

t (s) = - 1.7284

Using the t-distribution, as we have the standard deviation for the sample, it is found that the test statistic is given by:

d. -1.728

At the null hypothesis, it is tested if the batteries last at least 40 hours, that is:

[tex]H_0: \mu \geq 40[/tex]

At the alternative hypothesis, it is tested if they last less than 40 hours, that is:

[tex]H_1: \mu < 40[/tex]

The test statistic is given by:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

In this problem, the parameters are given by:

[tex]\overline{x} = 37.8, \mu = 40, s = 5.4, n = 18[/tex]

Hence:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{37.8 - 40}{\frac{5.4}{\sqrt{18}}}[/tex]

[tex]t = -1.728[/tex]

Hence option d is correct.

Step-by-step explanation:

X does not represent the cost of fabric. X represents the number of yards of fabric used.

15x + 250

Could be read as ($15 × # of yards) + $250

So she has to pay $15 per yard of fabric plus an additional $250 base amount for having them made and hung in the first place.

She could use an additional variable to represent the cost of fabric.

Example: Y

Y= 15x

Cost of fabric is equal to $15 per yard × # of yards.

The equation for the total cost depending on the number of students in Emma's Extreme Sports classes is C = 50 + 20x.

C = 50 + 20x

Where C represents the total cost, 50 is the fee per class, and 20 is the cost per student.

Answer:

Step-by-step explanation:

If you plot the vertex and the point that it goes through, the point it goes through is above the vertex, so the vertex is a positive one that opens upwards.  The general vertex form of a parabola of this type is

[tex]y=a(x-h)^2+k[/tex]

We have the x, y, h, and k.  We will plug all those in and solve for a.  That looks like this:

[tex]-5=a(6-4)^2-13[/tex] which simplifies to

-5 = 4a - 13 and

8 = 4a so

a = 2

That means that the paraobola in vertex form is

[tex]y=2(x-4)^2-13[/tex]

Answer:

The worth of the automobile after an year with 15% depreciation  is $22,100.

Step-by-step explanation:

The current cost of the automobile car = $26,000

The percentage of depreciation  = 15%

Now, calculating the depreciated amount:

15% of $26,000  = [tex]\frac{15}{100}  \times 26,000 = 3,900[/tex]

So, the depreciated amount of the car in the next year = $3,900.

Now, the worth of the car after an year

= CURRENT WORTH - THE DEPRECIATED AMOUNT

= $26,000 - $3,900.

= $22,100

Hence, the worth of the automobile after an year  is $22,100.

Answer:

$43,200

Step-by-step explanation:

Data provided in the question:

Cost of the asset = $80,000

Useful life of the machine = 5 years

Salvage value at the end of useful life = $20,000

Now,

Using the double declining method of depreciation

Annual depreciation rate = 2 ×  [1 ÷ useful life ]

= 2 × [ 1 ÷ 5 ]

= 2 × 0.2

= 0.4 or 40%

thus,

The depreciation from October 1, 2014 to December 31, 2014

= Annual Depreciation rate × duration × Book value for 2014

= 0.4 × 3 months × $80,000

= 0.4 × 0.25 year × $80,000

= $8,000

Book value for 2015

= Cost - depreciation till December 31, 2014

= $80,000 - $8,000

= $72,000

Therefore,

Depreciation for the year 2015

= Annual Depreciation rate  × Book value for 2015

= 0.4 × $72,000

= $28,800

Therefore,

Step-by-step explanation:

the answer is (-4,2)

Answer:

option C) (7, -2)

Step-by-step explanation:

By the graph, the initial coordinates of point A are ( -5, -4)

first reflection along the line x=1, only the x coordinate will change.

the new x coordinate is = x = 7

thus the point becomes (7, -4)

similarly, reflection along y= -3, only the y coordinate will change.

the new y coordinate is = y = -2

thus the final coordinates are (7, -2)

If the coefficient of determination is a positive value, then the regression equation could have either a positive or a negative slope.

If the coefficient of determination is a positive value, then the regression equation could have either a positive or a negative slope.

The coefficient of determination, denoted as r², is equal to the square of the correlation coefficient, r. It represents the percentage of variation in the dependent variable, y, that can be explained by variation in the independent variable, x, using the regression line. When r² is positive, it indicates a positive relationship between x and y, but it does not specify the direction of the slope.

Therefore, if the coefficient of determination is positive, the regression equation could have either a positive or a negative slope.

Answer:

The value of x is 3 cm.

Step-by-step explanation:

Given,

Total surface area of cuboid = 112 cm^2

Height of cuboid = 10 cm

Breadth of cuboid = 2 cm

Length of cuboid = x cm

Solution,

Formula for total surface of cuboid = [tex]2\times(length\times breadth +breadth\times height+height\times length)[/tex]

∴[tex]112=2(x\times2+2\times10+10\times x)\\112=2(2x+20+10x)\\112=2(12x+20)\\12x+20=\frac{112}{2}\\12x+20=56\\12x=56-20\\12x=36\\x=\frac{36}{12}=3[/tex]

Thus the length of cuboid is 3 cm.

Answer:

a) 95% confidence interval estimate of the true weight is (3.026, 3.274)

b) 99% confidence interval estimate of the true weight is (2.944, 3.356)

Step-by-step explanation:

Confidence Interval can be calculated using M±ME where

And margin of error (ME) can be calculated using the formula

ME=[tex]\frac{t*s}{\sqrt{N} }[/tex] where

Using the numbers 95% confidence interval estimate of the true weight is:

3.150±[tex]\frac{2.776*0.1}{\sqrt{5} }[/tex]≈3.150±0.124

And 99% confidence interval estimate of the true weight is:

3.150±[tex]\frac{4.604*0.1}{\sqrt{5} }[/tex]≈3.150±0.206
