Answer:
The approximate value of milos car 11 years after he purchased it is 3929.
Step-by-step explanation:
The given equation is
[tex]y=20646(0.86)^x[/tex]
Here, y is the estimates the value of a brand of car x years after it was purchased new.
We have to find the approximate value of milos car 11 years after he purchased it.
Substitute x=11 in the given equation.
[tex]y=20646(0.86)^{11}[/tex]
[tex]y=3929.33346204[/tex]
[tex]y\approx 3929[/tex]
Therefore the approximate value of milos car 11 years after he purchased it is 3929.

Find the value of x if C is the midpoint of AB, AC=4x+5, and AB=78
Given that AC = 4x+5, and C is the midpoint of AB, meaning AC = CB, then AB = 2*(4x+5). Given that AB = 78, we can solve the equation 8x + 10 = 78 to find x = 8.5.
Explanation:The subject matter of this question is geometry, specifically concerning line segments and midpoints. If C is the midpoint of AB, then segments AC and CB are equal. This is a fundamental characteristic of midpoints.
Since AC = 4x + 5 and CB = AC, it also means that CB = 4x + 5. This implies that the total length of AB (which is the sum of AC and CB) equals 2 * (4x + 5). Therefore, AB equals 8x + 10.
We are given that AB = 78. So, we can set up and solve the equation 8x + 10 = 78. Subtracting 10 from both sides of the equation gives us 8x = 68. Dividing each side by 8 gives us x = 8.5. Therefore, the value of x that satisfies the given conditions is 8.5.

A cone is 10 inches tall and has a radius of 3 inches. What is the cone’s volume?
94.25 is the cone’s volume according to the given information.
What is volume?Volume is a measurement of three-dimensional space that is inhabited. It is frequently expressed quantitatively utilizing SI-derived units, as well as several imperial or US-standard units. Volume and the of length are connected.
The space covered inside an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the material's potential.
Area of the base is πr² where r is the radius.
Area of the base = πr²
The volume of a cone is ⅓ πr²h where h is the height.
The volume of the cone = ⅓ πr²
The cone and circle will be treated in the same equation
So the volume is
= ⅓ π×9×10
=30 π
= 94.25 approximately.

There are 34 animals in a farmyard. some are cows and some are chickens. in total there are 104 legs. how many chickens are there?
Using a system of equations, the number of chickens that are there is calculated as: 16.
How to find how many chickens are there using system of equations?Let's set up and solve the system of equations:
C + Ch = 34 (Total number of animals)
4C + 2Ch = 104 (Total number of legs)
Use a method like substitution or elimination to solve the system. Let's use elimination:
Multiply equation 1 by 2 to make the coefficients of 'Ch' in both equations the same:
2C + 2Ch = 68
Subtract equation 1 from equation 2:
(4C + 2Ch) - (2C + 2Ch) = 104 - 68
This simplifies to:
2C = 36
C = 18
Now that we know there are 18 cows, we can find the number of chickens using equation 1:
18 + Ch = 34
Subtract 18 from both sides:
Ch = 34 - 18
Ch = 16
So, there are 16 chickens on the farm.

Graph each line y -7 = x + 4
To graph y - 7 = x + 4, rewrite the equation in slope-intercept form as y = x + 11. Plot the y-intercept at (0, 11), choose another value for x to find a second point, like (1, 12), and draw the line through these points to visualize the dependence of y on x.
Explanation:To graph the line given by the equation y - 7 = x + 4, we first need to write it in the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. So, we add 7 to both sides of the equation to get y = x + 11. This tells us the slope of the line is 1 (since for every increase by 1 in x, y increases by 1) and the y-intercept is 11 (this is where the line crosses the y-axis).
We can then plot the y-intercept on the graph by putting a point at (0, 11). To find another point, we can choose any value for x and solve for y. For example, if we choose x = 1, then y = 1 + 11 = 12, so another point on the line is (1, 12). By plotting these two points and drawing a line through them, we create the graph of the equation.
For more accurate results, plotting more points using various x values and connecting them would be ideal. This graphical representation illustrates the dependence of y on x.

At rugby practice, a group of 8 players stands in a circle and throws the ball from one person to the next. another player is trying to run faster than the ball moves around the circle as it is thrown from one player to the next. After 24 throws, the runner is right next to the ball. If the radius of the circle is 9yd, how many yards has the runner traveled? round your answer to the nearest tenth
Final answer:
The runner traveled approximately 45.1 yards around the circle during 24 throws at rugby practice.
Explanation:
The runner traveled approximately 45.1 yards.
To solve this, we can consider the circumference of the circle formed by the players, which is 2π times the radius. After 24 throws, the runner would have traveled a distance equivalent to 24 times the circumference of the circle.
So, the total distance the runner traveled would be 24 * (2π * 9) = 24 * 56.5487 = approximately 1357.2yd. Rounding to the nearest tenth, the runner traveled approximately 45.1 yards.
A certain elevator can hold no more than 2500 pounds. Define a variable and write an inequality for this situation
Let x represent the total weight in pounds of people and items. The inequality is x≤2500 for the elevator's weight limit.
Let's define the variable x to represent the weight in pounds of the people and items inside the elevator.
The inequality representing the situation would be:

Right trapezoid WXYZ is shown. What is the measure of angle WXY?
Answer: [tex]107^{\circ}[/tex]
Explanation: Here, WXYZ is a quadrilateral where, \angle WZY and \angle ZYX are right angles ⇒[tex]\angle WZY=\angle ZYX =90^{\circ}[/tex]
And, [tex]\angle XWZ= 73^{\circ}[/tex]
Since, The sum of all angles of a quadrilateral is equal to 360^{\circ}
Therefore,
[tex]\angle WXY+\angle XWZ+\angle WZY+\angle ZYX =360^{\circ}[/tex]
⇒[tex]\angle WXY+73^{\circ}+90^{\circ}+90^{\circ}=360^{\circ}[/tex]
⇒[tex]\angle WXY=360^{\circ}-253^{\circ}=107^{\circ}[/tex]
Answer:
C. [tex]107^{\circ}[/tex]
Step-by-step explanation:
We have been given an image of a right trapezoid and we are asked to find the measure of angle WXY.
We can see from our given trapezoid that angle XYZ and angle WZY measures 90 degrees.
Since we know that trapezoid is a quadrilateral and sum of all angles of a quadrilateral equals [tex]360^{\circ}[/tex], so we can set an equation as:
[tex]m\angle WXY+m\angle XYZ+m\angle YZW+m\angle ZWX=360^{\circ}[/tex]
Upon substituting the given measures of our trapezoid we will get,
[tex]m\angle WXY+90^{\circ}+90^{\circ}+73^{\circ}=360^{\circ}[/tex]
[tex]m\angle WXY+253^{\circ}=360^{\circ}[/tex]
[tex]m\angle WXY+253^{\circ}-253^{\circ}=360^{\circ}-253^{\circ}[/tex]
[tex]m\angle WXY=107^{\circ}[/tex]
Therefore, the measure of angle WXY is 107 degrees and option C is the correct choice.
Consider the graph of the quadratic function y = 2x2 – 4x + 2. How many zeros does the graph have?
The graph has:
One zero with multiplicity 2.
Step-by-step explanation:We are given a quadratic function in terms of the variable x as:
[tex]y=2x^2-4x+2[/tex]
The number of zeros of this function is equal to the number of points where the graph of this quadratic function intersects the x axis and the corresponding value of x is the root of this quadratic equation.
Hence, after plotting the graph of this quadratic function we observe that the graph meets the x-axis at just one point.
Hence, the number of zeros of the graph is:
One.
