Answer:

The diagonal of a square with 90 ft. per side is 127.28 which should be rounded down to 127 and the throw from 2nd to 3rd is 90 ft totaling 217 ft

The baseball moves 217.4 feet across the field in total.

Measured from the middle of the backstop to the apex of the home plate. Place second base in the centre by drawing a line from the backstop's centre point over the pitcher's mound, through the apex. The distance that needs to be measured is between the centre of the second base and the top of the home plate.

So we are given that each side of a square is 90 feet.

By finding how far the ball will travel, we are basically finding the distance from 2nd base to home

Well, let's picture a baseball field, and we find out that they are diagonal across from one another.

Well, let's draw a diagonal connecting home to 2nd base.

Since the field is a square, it has a right angle at 1st base

We now know 2 legs in a right triangle, which calls for the Pythagorean Theorem

(You could also do a 45-45-90 special right triangle, which would give you the answer very quickly)

So we have 90²+90²=c²

Which is

16200=c²

We are finding c

, so √16200=c

We can simplify this to √162⋅100 which is 10√162

Then we can simplify this to 10√81⋅2, that is 10⋅9√2

Finally, we multiply the values outside of the root to get = 90√2

the throw from 2nd to 3rd is 90 ft

total distance covered = 90 + 90√2

total distance covered = 217.4

Therefore, baseball travels in the field a total of 217.4 feet

The number of multiples of 9 is 211

Step-by-step explanation:

Note that the first multiplo of 9 between 100 and 2000 is number 108. The last multiple of 9 is 1998.

If we use the arithmetic sequence to perform the calculation

[tex]a_n = a_1 + d(n - 1)[/tex]

So the first term [tex]a_1[/tex] is:

[tex]a_1 = 108[/tex]

The last term [tex]a_n[/tex] is

[tex]a_n = 1998[/tex]

The common difference is

[tex]d = 9[/tex]

Thus

[tex]1998 = 108 + 9(n-1)[/tex]

We solve the equation for n and obtain the number of multiples of 9.

Slope is rise/run

This graphs shows the line going up by 2 and to the right 3

The graph that has a slope equal to 2/3 is Option(C) .

Slope of a straight line is defined as the inclination of the line with respect to the coordinate axis. The slope is also measure of the tangent of angle with which the line is inclined to the axis.

Slope of a straight line can be found using two given points say (x1,y1) and (x2,y2).

Slope (m) = (y2 - y1) / (x2 - x1) .

We check the graph at Option(C).

The coordinate of the point where the graph has 2 units distance with the y-axis is (4.5,2) and the coordinate of the point where the graph has 3 units distance with the x-axis is (1.5,0).

We have y2 = 2 , y1 = 0, x1 = 4.5, x2 = 1.5 .

Thus slope = (y2  y2)/(x2 - x1) = (2 - 0)/(4.5 - 1.5) = 2/3

Therefore, the graph that has a slope equal to 2/3 is the graph in  Option(C) .

The upper value of the confidence interval is 0.478.

A confidence interval is a range of values that are constrained by the statistic's mean and that are likely to include an unidentified population parameter. The proportion of likelihood, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn several times is referred to as the confidence level.

Given:

A random sample of 150 people from Iowa has been given cholesterol tests, and 60 of these people had levels over the "safe" count of 200. Construct a 95% confidence interval for the population proportion of people in Iowa with cholesterol levels over 200.

p' = 60/150

p' = 0.4

n = 150

95% Â → z(1-a/2) = 1.96

So the interval is:

[0.4 - 1.96{sqrt(0.4(0.6)/150)}], 0.4 + 1.96{sqrt(0.4(0.6)/150)}

= (0.322, 0.478)

Using the confidence interval formula for a proportion, we find that the upper limit is approximately 0.468, indicating a maximum of 46.8% of the population might have cholesterol levels above 200 with 95% confidence.

First, calculate the sample proportion (p) by dividing the number of positive outcomes (60) by the total sample size (150), which gives us p = 0.4. The formula for the confidence interval of a proportion is given by p ± Z*√(p(1-p)/n), where Z is the Z-score corresponding to the confidence level (for 95%, Z = 1.96), p is the sample proportion, and n is the sample size. Plugging in the values, we calculate:

Lower limit = 0.4 - 1.96*√(0.4*0.6/150) ≈ 0.332

Upper limit = 0.4 + 1.96*√(0.4*0.6/150) ≈ 0.468

The upper value of the confidence interval is approximately 0.468, which means we are 95% confident that the true proportion of people in Iowa with cholesterol levels over 200 is less than 46.8%.

Answer:

Critical points of an equation are the zeroes of its first derivative. Since you have already provided me with the derivative (thanks for saving me the effort :) ), I am just going to start the process.

tan (x) + x(sec^2(x)) = 0

Solving this equation (using a graphing calculator set to radians), it is only true when x = 0.

So, 0 is a critical point of this function.

Hope this helped!

The derivative of tan(x) is sec^2(x) and the critical points for xtanx occur at x = π/2 + nπ.

Derivative of tan(x) can be found by using the formula: d/dx(tan(x)) = sec^2(x). Critical points for xtanx can be obtained by setting the derivative equal to zero and solving for x. In this case, the critical points are where sec^2(x) = 0, which occurs when x = π/2 + nπ, where n is an integer.

Answer:

The graph c.

Step-by-step explanation:

We know from the function f(x) = 5sin(-2t) three things:

1. The amplitude is 5.

2. The period is π.

3. Because of the negative in the argumen, the graph will be reflected over the y-axis (Compared to the graph of sin(x))

Then, evaluating all the functions we find:

1. All of graphs have an amplitude of 5.

2. The graph b has a period of 2π.

3. The graph a is not reflected over the y-axis.

Then, the correct graph is the graph letter C.

The Graph of the function f(t) = 5 sin(-2t) is graph (b) in the image you provided.

This can be seen by noting that the function f(t) = 5 sin(-2t) is a sine function with a period of π, amplitude of 5, and horizontal shift of π/2 to the right. Graph (b) in the image matches these characteristics.

Amplitude: The amplitude of the function is 5, which is the absolute value of the coefficient in front of the sine term.

Period: The period of the function is π/2, which is the reciprocal of the absolute value of the coefficient multiplying the t term.

Phase shift: The function has a phase shift of π, which means that the graph is shifted to the left by π units.

The graph on the left has all of these features:

It has an amplitude of 5.

It has a period of π/2.

It is shifted to the left by π units.

The other graphs in the image do not match these characteristics:

Graph (a) has a period of 2π, not π.

Graph (c) has an amplitude of 1, not 5.

Graph (d) has a horizontal shift of −π/2, not π/2.

Step-by-step explanation:

x² + 10x + 24 = 0

Here, a = 1, b = 10, c = 24.  Factoring using the AC method:

ac = 1×24 = 24

Factors of 24 that add up to 10 are +4 and +6.

Therefore:

(x + 4) (x + 6) = 0

x + 4 = 0, x + 6 = 0

x = -4, x = -6

The roots are -4 and -6.  Added together:

-4 + -6 = -10

Answer A.

The required sum of the roots of the quadratic equation x² + 10x + 24 = 0 is -10.

In mathematics, the roots of an equation are the values of the variable that satisfy the equation.

Here,
To find the roots of the quadratic equation x² + 10x + 24 = 0, we can use the quadratic formula,

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 1, b = 10, and c = 24. Substituting these values, we get:

x = (-10 ± √(10² - 4(1)(24))) / (2(1))

x = (-10 ± √4) / 2

x = -5 ± 1

Therefore, the roots of the quadratic equation are x = -4 and x = -6.

The sum of these roots is -4 + (-6) = -10

Therefore, the sum of the roots of the quadratic equation x² + 10x + 24 = 0 is -10.

Answer:

Write formulas for the amount of $ that would be due each of the two companies and set these equal to one another prior to solving for the number of days:

A:  $35 + ($0.45/mile)x  

B:  $60 + ($0.25/mile)x

Then $35 + ($0.45/mile)x = $60 + ($0.25/mile)x, or

($0.20/mile)x = $25

                                                                       $25

dividing both sides by $0.20 yields  x = ------------------- = 125 miles

                                                                    $0.20/mile

The charges made by the two companies would become equal after the 125th mile.  After that, Company B would become cheaper.

Ms. Call would need to drive at least 125 miles for the rental from Company B to be more cost-effective.

To find out when Company B becomes a better deal, we need to set up an equality and solve it for the number of miles. We can create the equation as follows:

Company A cost = Company B cost.

So, $35 + $0.45x = $60 + $0.25x.

Here x represents the number of miles driven. If we simplify this equation, we have:

$0.20x = $25.

Thus, solving for x: x = 25/0.20 = 125

So, Ms. Call would need to drive at least 125 miles in order for Company B to be a better deal.

Final answer:

To evaluate the line integral of the given vector field along the line segment, parametric equations are established, and the integral is simplified to a single-variable integral, resulting in a value of 12.

Explanation:

To evaluate the line integral of f=yi+xj+3k along the segment from (4,4,2) to (5,8,-4), first we find parametric equations for the line segment. The parametric equations are x=4+t, y=4+4t, z=2-6t, where t varies from 0 to 1. We then express the vector field in terms of t, yielding f(t) = (4+4t)i + (4+t)j + 3k. The derivative of the vector position is dr/dt = i + 4j - 6k. The line integral becomes an integral with respect to t, from 0 to 1, of the dot product of f(t) and dr/dt, which simplifies to ∫(8 + 52t - 18)dt = ∫(44t - 10)dt.

Integrating from 0 to 1 gives the final answer as 22 - 10 = 12. This approach demonstrates how converting a line integral into a single-variable integral simplifies the calculation.
