Step-by-step explanation:

Assuming a circular track

Outside track is 3 m 'thicker ' so the diameter is (44 + 3 + 3) = 50 m

Outside track circumference = pi * d =  pi * 50 = 50 pi m

  Inside track circumference = 44 pi

Outside 10 laps = .500 pi   KM     time = .5 pi  km / 4.5 km/hr = .3490658 hr

Inside 10 laps = .444 pi KM            time = .444 pi km / 4.5 km/hr = .309974

The graph equation has been plotted on the graph which crosses the points  (0, 10) and (20, 0) on the y and x axis.

Write the equation in the form y = MX + b to determine the slope m and the y-intercept.

This will allow you to graph the equation using the slope and y-intercept (0, b).

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

So, we have the equation:

8x+16y=160

Where:

x represents the short sleeves.

y represents the long sleeves.

Now, we need to plot the equation as follows:

The required probability is approximately 0.0228 that the diameter is greater than 85 millimeters.

The probability that the diameter of a selected bearing is greater than 85 millimeters can be found by calculating the z-score for 85 millimeters and then using the standard normal table to find the corresponding probability.

First, we need to standardize the value 85 millimeters by subtracting the mean diameter and dividing by the standard deviation:

z = (85 - 81) / (4 / sqrt(16)) = 4 / 2 = 2

Next, we can use the standard normal table to find the probability that a randomly selected bearing has a diameter greater than 85 millimeters.

Since the distribution is symmetric, we can find the probability that the diameter is less than 85 millimeters and then subtract this probability from 1 to find the probability that the diameter is greater than 85 millimeters. Looking up the z-score 2 in the standard normal table, we find that the probability that the diameter is less than 85 millimeters is approximately 0.9772.

Therefore, the probability that the diameter is greater than 85 millimeters is approximately 1 - 0.9772 = 0.0228.

Step-by-step explanation:

The four tables available in choices, table option D is not a function. This is because there is the same x value, x = 2 i.e : ( 2, 3 ) , ( 2, 5 ) , ( 2, 7 ).

What is Function?

Function is a relation which each member of the domain is mapped onto exactly one member of the codomain.

There are many types of functions in mathematics such as :

Linear Function → f(x) = ax + b

Quadratic Function → f(x) = ax² + bx + c

Trigonometric Function → f(x) = sin x or f(x) = cos x or f(x) = tan x

Logarithmic function → f(x) = ln x

Polynomial function → f(x) = axⁿ + bxⁿ⁻¹ + ...

If function f : x → y , then inverse function f⁻¹ : y → x

Let us now tackle the problem!

According to the definition above, it can be concluded that a function cannot have the same x value.

Of the four tables available in choices, table option D is not a function. This is because there is the same x value, x = 2 i.e :

     Concave down:  (-2, -1)

     Points of inflection:  (-2, 0) and (-1, -1)

D)  See attachments.

Step-by-step explanation:

Given function and derivatives:

[tex]f(x) = x(x+2)^3[/tex]

[tex]f'(x) = (4x+2)(x+2)^2[/tex]

[tex]f''(x) = 12(x+1)(x+2)[/tex]

[tex]\textsf{A function is \textbf{increasing} when the \underline{gradient is positive}}\implies f'(x) > 0[/tex]

[tex]\textsf{A function is \textbf{decreasing} when the \underline{gradient is negative}} \implies f'(x) < 0[/tex]

Increasing function

[tex]\begin{aligned}f'(x) & > 0\\(4x+2)(x+2)^2 & > 0\\2(2x+1)(x+2)^2 & > 0\\(2x+1)(x+2)^2 & > 0\end{aligned}[/tex]

Therefore, the function is increasing on the Interval:

[tex]\left(-\dfrac{1}{2}, \infty \right)[/tex]

Decreasing function

[tex]\begin{aligned}f'(x) & < 0\\(4x+2)(x+2)^2 & < 0\\2(2x+1)(x+2)^2 & < 0\\(2x+1)(x+2)^2 & < 0\end{aligned}[/tex]

Therefore, the function is decreasing on the Interval:

[tex](- \infty, -2) \cup \left(-2,-\dfrac{1}{2} \right)[/tex]

Local minimum/maximum points occur when f'(x) = 0.

[tex]\begin{aligned}f'(x) &= 0\\(4x+2)(x+2)^2 & = 0\\2(2x+1)(x+2)^2 & = 0\\(2x+1)(x+2)^2 &= 0\\\\2x+1&=0 \implies x=-\dfrac{1}{2}\\(x+2)^2&=0 \implies x=-2\end{aligned}[/tex]

[tex]f''\left(-\dfrac{1}{2}\right) = 12\left(-\dfrac{1}{2}+1 \right)\left(-\dfrac{1}{2}+2 \right)=9 > 0\implies \textsf{minimum}[/tex]

[tex]f''\left(-2\right) = 12\left(-2+1 \right)\left(-2+2 \right)=0\implies \textsf{point of inflection}[/tex]

Therefore, the value of x where f(x) has a local minimum is x = -¹/₂.

At a point of inflection, f''(x) = 0.

[tex]\begin{aligned}f''(x) &=0\\12(x+1)(x+2)&=0\\(x+1)(x+2)&=0\\\\x+1&=0 \implies x=-1\\x+2&=0 \implies x=-2\end{aligned}[/tex]

Substitute the found values of x into the original function to the find the y-coordinates of the points of inflection:

[tex]\implies f(-1) = -1(-1+2)^3=-1[/tex]

[tex]\implies f(-2) = -2(-2+2)^3=0[/tex]

Therefore, the inflection points are:

A curve y = f(x) is concave up if f''(x) > 0 for all values of x.

A curve y = f(x) is concave down if f''(x) < 0 for all values of x.

Concave up

[tex]\implies f''(x) > 0[/tex]

[tex]\implies 12(x+1)(x+2) > 0[/tex]

[tex]\implies (x+1)(x+2) > 0[/tex]

Therefore, the function is concave up at:

[tex]\left(-\infty,-2\right) \cup \left(-1,\infty \right)[/tex]

Concave down

[tex]\implies f''(x) < 0[/tex]

[tex]\implies 12(x+1)(x+2) < 0[/tex]

[tex]\implies (x+1)(x+2) < 0[/tex]

Therefore, the function is concave down at:

The equation of a hyperbola with a=7 and c=9 is (x-0)²/a²-(y-0)²/b²=1, x²/49-y²/32=1.

A hyperbola is a kind of smooth curve that appears to lie in a plane. It is made up of two connected components or branches that are mirror reflections of one another and look like two infinite bows. A hyperbola is a collection of points whose difference in distance between two foci is a fixed amount. This discrepancy is calculated by subtracting the distance from the farther focus from the distance from the closest focus.

As we know the standard equation of the hyperbola with a horizontal transverse axis is:

(x-h)²/a²-(y-k)²/b²

Now, put the given values a=7 and c=9 in the Pythagorean theorem to get the value of b.

c²=a²+b²

(9)²=(7)²+b²

81=49+b²

81-49=b²

32=b²

Now square root both sides:√

32=√b²

√32=b

Assuming that the center of a hyperbola is (0,0):

(x-0)²/a²-(y-0)²/b²=1

x²/a²-y²/b²=1

x²/(7)²-y²/(√32)²=1

x²/49-y²/32 = 1

Therefore, the equation of a hyperbola with a=7 and c=9 (x-0)²/a²-(y-0)²/b²=1, x²/49-y²/32=1.

Answer:

Isabella spent $1302.52 and Jesus spent $1740.99.

Step-by-step explanation:

In order to figure out how much each individual person spent, we need to write a mathematical equation to express this situation. An equation in math is a statement that relates two expressions that are equal in value, and can be used to solve for variables. A linear equation with one variable is often presented in is standard form, [tex]ax+b=0[/tex].

In this case, we can represent the amount that Isabella spent with the variable x. Since Jesus spent $438.47 more than Isabella, this amount can be represented with x + 438.47. We can set up our equation as follows:

[tex]x+(438.47+x)=3043.51[/tex]

*Note that the use of parentheses is not necessary but may be useful in making your work clearer!

To solve for x, we should combine like terms and then move the variables to one side and constants to the other. The variable can be isolated by subtracting 438.47 from 3043.51:

Now that we have the variable by itself, we can divide by 2 on both sides to solve for x.

As we defined, x equals the amount of money that Isabella spent, which is $1302.52. We can plug that number into x + 438.47 to get the amount that Jesus spent, which we calculate to be $1740.99.

Thus, Isabella spent $1302.52 and Jesus spent $1740.99.

To check our work, we can simply add up the two amounts to see if it totals to $3043.51:
