Answer:

Step-by-step explanation:

When Riko left his house, Yuto was 5.25 miles along the path.

Average speed of Riko = 0.35 miles per minute

Average speed of Yuto = 0.25 miles per minute

First we will calculate the time in which Riko will catch Yuto on the track.

Relative velocity of Riko as compared to Yuto will be = velocity of Riko - velocity of Yuto

= 0.35 - 0.25

= 0.10 miles per minute

Now we this relative velocity tells that Riko is moving and Yuto is in static position.

By the formula,

Average speed = [tex]\frac{Distance}{Time}[/tex]

0.10 = [tex]\frac{5.25}{t}[/tex]

t = [tex]\frac{5.25}{0.1}[/tex]

t = 52.5 minutes

Now we know that Rico will catch Yuto in 52.5 minutes. Before this time he will be behind Yuto.

So duration of time in which Rico is behind Yuto will be 0 ≤ t ≤ 52.5

Here time can not be less than zero because time can not be with negative notation. It will always start from 0.

Answer:

Sample Response:

The solution means that Riko will be behind Yuto from the time she leaves the house, which corresponds to t = 0, until the time she catches up to Yuko after 52.5 minutes, which corresponds to t = 52.5. The reason that t cannot be less than zero is because it represents time, and time cannot be negative.

Step-by-step explanation:

There are about 110,000 days in 300 years, so the expected number of failures is about 10/11 ≈ 1.

_____

This assumes the launch conditions are identical for each of the launches, or that whatever variation there might be has no effect on the probability. These are bad assumptions.

A failure rate of 1 in 100,000 with daily launches over 300 years would statistically result in approximately 1 failure.

If the chance of a space shuttle failure is 1 in 100,000, we can calculate the expected number of failures over 300 years with the assumption that a shuttle is launched every day. There are 365 days in a year, so over 300 years, there would be 300 × 365 = 109,500 launches. Given the failure rate of 1 in 100,000, we would then expect approximately 109,500 / 100,000 = 1.095 failures, which rounded to the nearest integer is 1 failure.

In other words, if the failure rate estimated by the shuttle program management were accurate and a shuttle was launched every day for 300 years, one would expect about 1 failure during that time span.

Answer:

y=4x-4

Step-by-step explanation:

The equation of a line is slope-intercept form is: y=mx+b where m is the slope and b is the y-intercept. This is the required form I think. Your document says write in slope... can't read the rest because it is cut off.

I'm actually going to use point-slope form which is: y-y1=m(x-x1) where m is the slope and (x1,y1) is a point we know that is on the line.

We have m=4.

We can actually find a point on the line. Both the line and the curve y=x^2 cross at x=2.

So we find the corresponding y-coordinate on our line to x=2 by plugging into x^2.

x^2 evaluated at x=2 gives us 2^2=4.

So we have the slope m=4 and a point (x1,y1)=(2,4) on the line.

Let's plug it into the point-slope form:

y-4=4(x-2)

Now the goal was y=mx+b form so let's solve our for y.

y-4=4(x-2)

Distribute 4 to terms in ( ):

y-4=4x-8

Add 4 on both sidea:

y=4x-4

3/5 - 1/10 is the amount of space in the bank that the 440 pennies took up, or

1/2.  Use proportions to solve this, with number of pennies on the top and the fraction of the bank that is filled on the bottom:

[tex]\frac{440}{\frac{1}{2} }=\frac{x}{1}[/tex]

Explanation:

An absolute value function in the form ...

  f(x) = a|x -h| +k

will have its vertex at (x, y) = (h, k). The sign on scale factor "a" will tell you whether it opens upward (a > 0) or downward (a < 0).

If a is positive, the vertex is a minimum, and the range is [k, ∞).

If a is negative, the vertex is a maximum, and the range is (-∞, k].

The range of an absolute value function is determined by its vertex and the value of 'a'. If 'a' is positive, the function opens upwards and the minimum of the range is the y-coordinate of the vertex. If 'a' is negative, the function opens downwards, the maximum of the range is the y-value of the vertex.

The range of an absolute value function can be determined using the vertex and the value of 'a' in the function’s equation. In an absolute value function, the vertex is the lowest or highest point on the graph, depending on whether the function opens upwards or downwards. The value 'a' influences the direction of the opening: if 'a' > 0, the graph opens upwards, and if 'a' < 0, it opens downwards.

For example, consider the function |a(x-h)|+k, where (h,k) is the vertex. If 'a' is positive, then the minimum range of the function will be 'k', and the function will extend to positive infinity, making the range [k, ∞). If 'a' is negative, the function will extend towards negative infinity, making its maximum value 'k', and thereby setting the range to (-∞, k].

This means, for instance, if we have a function like y = 3|x - 2| + 1, the value of 'a' is 3, which is positive, thus the function opens upwards, and the vertex is (2,1), which indicates that the range of this function is [1,∞).

Step-by-step explanation:

Answer:

216.4 mm^2

Step-by-step explanation:

The polygon has 9 sides.

Divide the polygon into 9 congruent triangles. Each triangle has 2 sides of length 8.65 mm, so each triangle is isosceles. The measure of each internal angle of the polygon is (9 - 2)(180)/9 = 140 degrees. The base angles of an isosceles triangle measures 70 deg. The vertex angle measures 40 deg. Draw a segment from the center of the polygon to the midpoint of a side. This segment is the altitude of the triangle. Now the triangle has been split into two right triangles. The angles of the right triangle are 70, 90, and 20. 3.65 mm is the length of the hypotenuse. The length of the altitude is found with trig.

sin A = opp/hyp

sin 70 = h/8.65

h = 8.65 sin 70

h = 8.1283 mm

Now with the altitude, we can find the length of half of a side of the polygon.

a^2 + b^2 = c^2

x^2 + h^2 = 8.65^2

x^2 + 8.1283^2 = 8.65^2

x = 2.9585

Half a side measures 2.9585 mm.

The side of the polygon measures 5.9169 mm.

The area of the polygon is 9 times the area of one triangle.

area = 9 * base * height/2

area = 9 * 5.9169 mm * 8.1283 mm / 2

area of polygon = 216.4 mm^2

Answer:

Descartes' rule states that the possible number of the positive roots of a polynomial is equal to the number of sign changes in the coefficients of the terms or less than the sign changes by a multiple of 2.

The Fundamental Theorem of Algebra states that every polynomial equation over the field of complex numbers of degree higher than 1 has a complex solution, furthermore any polynomial of degree n has n roots.  

Remember that the complex numbers include the real numbers.

Suppose we are given the polynomial x^3+3x^2-x-x^4-2, we arrange the terms of the polynomial in the descending order of exponents:

-x^4+x^3+3x^2-x-2, count the number of sign changes, there are 2 sign changes in the polynomial, so the possible number of positive roots of the polynomial is 2 or 0.

returning to our polynomial above, -x^4+x^3+3x^2-x-2, it has degree 4 and so has n roots. Note that complex roots always come in pairs, so here is what can be said from these two rules:  

degree 1 has 1 real root

degree 2 has 2 real roots or 2 complex roots

degree 3 has 3 real roots or 1 real root and 2 complex roots

degree 4 has 4 real roots or 2 real roots and 2 complex roots  

note that if the degree is odd, there will be at least 1 real root

Step-by-step explanation:

The number of complex roots and the possible positive and negative real roots of a polynomial can be predicted using the Fundamental Theorem of Algebra and Descartes' Rule of Signs. The Fundamental Theorem of Algebra ensures at least one complex root for every polynomial, while Descartes' Rule predicts possible real roots based on the number of sign changes in the polynomial equation.

To predict the number of complex roots and find the number of possible positive and negative real roots to a polynomial, you can use both Descartes' Rule and the Fundamental Theorem of Algebra. These two concepts in mathematics can give us interesting insights into the roots of polynomial equations.

First, the Fundamental Theorem of Algebra states that every non-constant polynomial equation has at least one complex root. This theorem can ensure us that we have a starting point, knowing that every polynomial equation will have at least one solution, even if it's complex.

Second, you can use Descartes' Rule of Signs to predict possible positive and negative roots. This rule uses the number of sign changes in the polynomial to give possible number of positive real roots. You can get the possible number of negative real roots by replacing x with -x and count the sign changes again.

For example, for the equation f(x) = x5 – 4x4 + 2x3 + 8x2 -12x + 6, there are two sign changes in the original equation, so there can be two or zero positive real roots. If we replace x with -x, we get three sign changes, suggesting three or one negative real roots.

An important aspect to remember is that Descartes' Rule of Signs gives us possible quantities of roots, but not the exact amount or their values, and it can't predict complex roots. However, by utilizing the Fundamental Theorem of Algebra in conjunction with Descartes' Rule, we can get a fuller picture of the roots of a polynomial equation.

Answer:

y

Step-by-step explanation:

Flip b/x to the proportion x is now y.

Answer:

b/x = (x + y)/b

where c = x + y then

b/x = c/b

Step-by-step explanation:

Considering the larger of the three triangles the image represents,

b and a in light of the angle A form by both sides (the angle opposite the side a) would have a relationship

Cos A = x/b

hence b/x = 1/Cos A

Considering the largest triangle,

Cos A = b/(x +y)

hence,

(x + y)/b = 1/Cos A

as such,

b/x = (x + y)/b

y = k/x

We want to find k first.

4 = k/8

4(8) = (k/8)(8)

32 = k

We now need to find y knowing that k = 32 and x = 2.

y = k/x

y = 32/2

y = 16

Did you follow?

Answer:

16

Step-by-step explanation:

Inverse variation follows this equation:

y = k/x

We know one point, so we input x and y, and solve for k.

4 = k/8

k = 32

The inverse variation equation is

y = 32/x

Now we let x = 2, and use our equation to find y.

y = 32/2

y = 16

Answer:

Width 13, Length = 22

Step-by-step explanation:

Let L = length and W = width

Given, length is 9 more than width, ie.

L = W + 9  ----> eq 1

Also given that area = 286 square inches.

Area of rectangle = length x width , or

286 = L x W   -----> eq 2

2 equations, 2 unknowns => we can solve this system of equations by substitution.

Substitute eq 1 into eq 2,

286 = (W + 9) x W

286 = W² + 9W

W² + 9W - 286 = 0 (solve quadratic equation using your favorite method)

w = 13 or w = -22 (impossible since width cannot be negative)

hence W = 13 (substitute this back into equation 1)

L = 13 + 9 = 22

The width of the rectangle is 13 inches, and the length is 22 inches, obtained by solving the quadratic equation derived from the provided area and the relationship between the length and the width.

To find the length and width of a rectangle when given the area and the relationship between the length and the width, we can set up an algebraic equation. Let w represent the width and l represent the length of the rectangle. According to the problem, l = w + 9. The area of the rectangle, which is width times length, is given as 286 square inches, so our equation is w x (w + 9) = 286.

Solving this quadratic equation step by step:

Therefore, the width of the rectangle is 13 inches and the length is 22 inches.

The 3 known points of the parabola are the origin (0,0) and the bottom left and right points ( -5,-50) (5,-50)

The general form of a parabola that goes through the origin is:  

y = ax^2  

We need to solve for a:

-50 = a(5)^2  

-50 = 25a  

a = -50/25

a = -2

Now the equation of the parabola is y = (-2)x^2.

To solve for the vertical clearance (y) 2 meters from the edge

Subtract the distance from the edge 2 meters from the original edge which is 5 meters, 5-2 = 3.

Now replace x with 3 and solve for y:

y = (-2)3^2

y = -2(9)

y = -18

The clearance would then 50 - 18 = 32 meters.

Option 1:(x-4)^2+y^2=100

Step-by-step explanation:

Given center = (h,k) = (4,0)

The point (-2,8) lies on circle which means the distance between the point and center will be equal to the radius.

So,

The distance formula will be used:

[tex]d = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}} \\=\sqrt{(4+2)^{2}+(0-8)^{2}}\\=\sqrt{(6)^{2}+(-8)^{2}}\\=\sqrt{36+64}\\ =\sqrt{100}\\ =10\ units[/tex]

Hence radius is 10.

The standard form of equation of circle is:

(x-h)^2+(y-k)^2 = r^2

Putting the values

(x-4)^2+(y-0)^2=10^2

(x-4)^2+y^2=100

Hence option 1 is correct ..

Hope this helps C:

Everett McCook's annual payment for liability insurance can be calculated by dividing his total liability coverage by the annual distance he drives to college.

To determine Everett McCook's annual payment for liability insurance, we need to calculate the total premium he pays. Since he drives 5 miles each way to the college, his daily distance is 10 miles. To calculate his annual distance, we multiply this by the number of days he drives to college in a year. Assuming he works on all weekdays, he drives 5 days a week for 52 weeks, resulting in 260 days a year. Therefore, his annual distance is 260 * 10 = 2600 miles.

Now, let's calculate his annual payment. Since his liability insurance includes $50,000 for single bodily injury, $100,000 for total bodily injury, and $15,000 for property damage, we can add these amounts together. Therefore, his liability coverage is $50,000 + $100,000 + $15,000 = $165,000.

Lastly, we divide the total liability coverage by the annual distance to find the cost per mile. So, the annual payment is $165,000 / 2600 = $63.46 per mile.

Collecting data from a sample that does not represent the population is known as sampling bias. It leads to inaccurate results as it may not correctly represent the diversity or behaviors of the entire population. Researchers use random sampling methods to reduce bias, but may also use non-probability sampling acknowledging its limitations.

Collecting data from a sample that does not represent the population is called sampling bias. Sampling bias occurs when the elements selected for inclusion in a study do not accurately reflect the larger population from which they were drawn. This can lead to inaccurate results and conclusions because the sample may not capture the diversity or behaviors of the entire population. For instance, an online poll conducted by a newspaper may only reach individuals with internet access, thereby excluding a significant portion of the population. To mitigate sampling bias, researchers aim to utilize random sampling methods, such as simple random sampling, stratified sampling, cluster sampling, and systematic sampling, which give each individual in the population an equal chance of being selected.

However, due to constraints such as cost and feasibility, researchers may sometimes opt for non-probability sampling, like convenience sampling, acknowledging its limitations in representativeness. This highlights the importance of carefully choosing a sampling method that is as representative of the population as possible to ensure more accurate and generalizable results.
