Answer:

We know that the height equation is given by:

H(t) = -16*t^2 + 108*t + 28

in ft.

First, we want to find the maximum height of the ball.

The first thing we can see is that the leading coefficient of the quadratic equation is negative, this means that the arms of the graph will open downwards, so the vertex of the quadratic equation is the maximum.

We also know that the ball will reach its maximum height when its velocity is zero (this means that the object stops going upwards at this point).

To get the velocity equation we need to derivate the above equation, we will get:

V(t) = 2*(-16)*t + 1*108

V(t) = -32*t + 108

We need to find the value of t such that this is zero, we will get:

V(t) = 0 =  -32*t + 108

        32*t = 108

             t = 108/32 = 3.375

So the ball reaches its maximum height after 3.375 seconds.

Then the maximum height is given by the height equation evaluated in that time, we will get:

H(3.375) =  -16*(3.375)^2 + 108*3.375 + 28 = 210.25

Then the maximum height of the ball is 210.25 ft

The ball will hit the ground when:

H(t) = 0

Then we just need to solve:

0 =  -16*t^2 + 108*t + 28

Using the Bhaskara's equation we can find that the two solutions for t are:

\(t = \frac{-108 \pm \sqrt{(108)^2 - 4*(-16)*28} }{2*(-16)} = \frac{-108 \pm 116}{-32}\)

So the two solutions are:

t = (-108 + 116)/-32 = -0.25

t = (-108 - 116)/-32 = 7

Because t represents time, we should take only the positive value of time (as t = 0 is the time when the ball is thrown).

Then we can conclude that the ball hits the ground after 7 seconds.

-7(5-3x)=-35 what is the x in the problem

Answers

Answer:

x = 0

Step-by-step explanation:

-7(5-3x)=-35

Divide by -7

-7/-7(5-3x)=-35/-7

5 -3x = 5

Subtract 5 from each side

5-3x-5 = 5-5

-3x=0

Divide by -3

x=0

Answer: x = 0

Step-by-step explanation: Start by distributing the -7 through the parenthses on the left side of the equation.

-7(5) is -35 and -7(-3x) is 21x.

So we have -35 + 21x = -35.

Next, isolate the x term by adding 35 to both sides.

When we do this, we get 21x = 0.

Now divide both sides by 21 and x = 0.

Given =(5,-2, 3) and >= (1, 1, 2) find an ordered triple that represents 3u - 2v.

Answers

The ordered triple representing \(3u - 2v\) is \((13, -8, 5)\).

To find an ordered triple representing \(3u - 2v\),

where \(u = (5, -2, 3)\) and \(v = (1, 1, 2)\),

we can perform the following operations:

\(3u = 3(5, -2, 3)\)

\(3u = (15, -6, 9)\)

\(2v = 2(1, 1, 2)\)

\(2v = (2, 2, 4)\)

Now, subtracting 2v from 3u gives:

\(3u - 2v = (15, -6, 9) - (2, 2, 4)\)

\(3u - 2v = (15-2, -6-2, 9-4)\)

\(3u - 2v = (13, -8, 5)\)

Therefore, the ordered triple representing 3u - 2v is (13, -8, 5).

A large company that produces a "fat-burner" pill claims an average loss of 20 pounds in the first month. A consumer advocacy group believes that this claim is actually just "hype" intended to sell more of the compound. The advocacy group would like to obtain statistical evidence about this issue and takes a random sample of 100 consumers who responded that they had purchased the pill but didn't know what the survey was about. They find that these 100 people lost an average of 18 pounds with a standard deviation of 7.5 pounds. What are the null and alternative hypothesis in this situation

Answers

The null and alternative hypothesis for the tests are:

H0: μ = 20

Ha: μ < 20

Given data:

In this situation, the null and alternative hypotheses can be formulated as follows:

Null Hypothesis (H0): The average weight loss of consumers who take the "fat-burner" pill is equal to 20 pounds.

Alternative Hypothesis (Ha): The average weight loss of consumers who take the "fat-burner" pill is less than 20 pounds.

In symbolic notation:

H0: μ = 20

Ha: μ < 20

where μ represents the population mean weight loss of consumers who take the "fat-burner" pill.

The null hypothesis assumes that the claim made by the company is accurate and that the average weight loss is indeed 20 pounds. The alternative hypothesis challenges this claim and suggests that the actual average weight loss may be less than 20 pounds, implying that the "hype" around the pill's effectiveness might be exaggerated.

Find the slope of the graph of B.

Answers

There were 120150 federally insured bank in the year 1987. The slope of the graph of B is -326.6.

The provided function B(x) states the number of federally insured banks from 1982-2004.

The function B(x) is,

B(x) = -326.6t + 13783

Here t is representing the year,

This function is a linear function corresponding to an equation of line,

If according to the situation,

t = 0, signifies the year 1982,

Then the year 1983 should be represented by t = 1.

On continuing the pattern the year 1987 should be represented by t = 5.

So, the number of federally insured banks in year 1987 can be found by putting t = 5 in B(x),

B(5) = -326.6(5) + 13783

B(5) = 12150.

The number of banks federally insured in year 1987 is 12150.

The function is B(x)= -326.6t + 1783,

This is representing the point-slope form of the line,

y = mx + c,

On comparing the provided function with the standard equation we can see,

Slope m = -326.6

So the slope of the function is -326.6.

canyon? Explain your reasoning.

The distance between points A and B is 35 feet, the distance between points B and C is 35 feet, and the

Answers

The answer of the question based on distance and width of the canyon is width of the trapezoid is approximately 67.43 feet.

What is Trapezoid?

A trapezoid is  quadrilateral ( four-sided polygon) that has two parallel sides and two non-parallel sides. The parallel sides are referred to as  bases of the trapezoid, while the non-parallel sides are called  legs. The distance between  two parallel sides is called  height or altitude of trapezoid.

The figure in the provided link is a trapezoid with parallel sides AB and CD, and non-parallel sides BC and AD.

Since AB and CD are parallel, we know that the length of the altitude is the same as the distance between them.

Let's call the width of the trapezoid "x". Then, we can use the following equation using the Pythagorean Theorem:

(AC)^2 = (BC)^2 + (AB - CD + 2x)^2

where AC is the diagonal connecting points A and C.

Substituting the given values, we get:

(AC)^2 = (35)^2 + (35 - 80 + 2x)^2

(AC)^2 = 1225 + (2x - 45)^2

(AC)^2 = 1225 + 4x^2 - 180x + 2025

(AC)^2 = 4x^2 - 180x + 3250

Now, we can use the distance formula to find the length of AC:

AC = sqrt[(A - C)^2 + (B - D)^2]

AC = sqrt[(35 + 35)^2 + 80^2]

AC = sqrt[4900 + 6400]

AC = sqrt(11300)

AC = 106.23 feet (rounded to two decimal places)

Substituting the value in  equation above, we will get:

(106.23)^2 = 4x^2 - 180x + 3250

11299.77 = 4x^2 - 180x + 3250

4x^2 - 180x + 8049.77 = 0

Solving the quadratic equation using quadratic formula, we will get:

x = [180 ± sqrt(180^2 - 4(4)(8049.77))] / (2(4))

x = [180 ± sqrt(129322.08)] / 8

x = [180 ± 359.44] / 8

We take the positive root, since x represents a length, and we get:

x = (180 + 359.44) / 8

x = 67.43 feet (rounded to two decimal places)

Therefore, the width of the trapezoid is approximately 67.43 feet.

We have,

To evaluate the limit of the expression as x approaches 0, we can simplify the expression first.

The expression is given as lim(x approaches 0) (cosec(2x) - x cosec³(x)).

Using trigonometric identities, we can rewrite cosec(2x) as 1/sin(2x) and cosec³(x) as 1/(sin(x))³.

Substituting these into the expression,

We get lim(x approaches 0) (1/sin(2x) - x (1/(sin(x))³)).

Now, let's evaluate the limit term by term:

lim(x approaches 0) (1/sin(2x)) = 1/sin(0) = 1/0 (which is undefined).

lim(x approaches 0) (x (1/(sin(x))³))

= 0 (1/(sin(0))³)

= 0 x 1/0 (which is also undefined).

Since both terms of the expression are undefined as x approaches 0, we cannot determine the limit of the expression.

G1 = first card is green

Enter the probability as a fraction.
P(at least one green) = ______.

Answers

Answer:

\(P(G_1) = \frac{5}{13}\)

\(P(G_2) = \frac{1}{3}\)

\(P(X \ge 1) = \frac{25}{39}\)

Step-by-step explanation:

Given

\(G = 5\)

\(R = 4\)

\(B = 4\)

\(n = 13\)

Solving (a): \(P(G_1)\)

This is calculated as:

\(P(G_1) = \frac{G}{n}\)

\(P(G_1) = \frac{5}{13}\)

Solving (b): \(P(G_2)\)

This is calculated as:

\(P(G_2) = \frac{G - 1}{n - 1}\) -- this is so because the selection is without replacement

\(P(G_2) = \frac{5 - 1}{13 - 1}\)

\(P(G_2) = \frac{4}{12}\)

\(P(G_2) = \frac{1}{3}\)

Solving (c): \(P(X \ge 1)\)

Using the complement rule, we have:

\(P(X \ge 1) = 1 - P(X = 0)\)

To calculate \(P(X = 0)\), we have:

\(G = 5\) --- Green

\(G' = 8\) ---- Not green

The probability that both selections are not green is:

\(P(X = 0) = P(G'_1) * P(G'_2)\)

So, we have:

\(P(X = 0) = \frac{G'}{n} * \frac{G'-1}{n-1}\)

\(P(X = 0) = \frac{8}{13} * \frac{8-1}{13-1}\)

\(P(X = 0) = \frac{8}{13} * \frac{7}{12}\)

Simplify

\(P(X = 0) = \frac{2}{13} * \frac{7}{3}\)

\(P(X = 0) = \frac{14}{39}\)

Recall that:

\(P(X \ge 1) = 1 - P(X = 0)\)

\(P(X \ge 1) = 1 - \frac{14}{39}\)

Take LCM

\(P(X \ge 1) = \frac{39 -14}{39}\)

\(P(X \ge 1) = \frac{25}{39}\)

Write a quadratic equation that fits each set of points.

Answers

The quadratic equation that fits each set of points (0.-8), (2, 0), and (-3, -5) is -3x² + 10x - 8 = 0

Quadratic equation:

Quadratic equation refers algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

Given,

Here we have the set of points (0.-8), (2, 0), and (-3, -5).

Now, we have to find the quadratic equation for this points.

We know that the standard form of the quadratic equation is,

y = ax² +  bx + c

Here we have to use each point value in order to find the value of a, b and c to find the quadratic equation of the points,

First we have to take the point (0, -8) and apply it on the formula, then we get,

-8 = a(0)² +  b(0) + c

-8 = c

Now, use the point (2,0), then we get,

0 = a(2)² +  b(2) + c

0 = 4a + 2b + c --------------------(1)

Finally, take the point (-3, -5), then we get the equations,

-5 = a(-3)² +  b(-3) + c

-5 = 9a - 3b + c --------------------(2)

Now, apply the value of c as -8, then we get,

4a + 2b = 8 ----------------(3)

9a -3b = 3 -----------------(4)

Divide equation (4) by 3 and equation (3) by 2 on both sides then we get,

2a + b = 4

3a - b = 1

When we subtract these equation then we get the value of

a = -3

Then the value of b is

2(-3) + b = 4

b = 4 + 6

b = 10

Therefore, the quadratic equation is -3x² + 10x -8 = 0
