The tangent line AC forms a right angle with the radius line OC, so the angle at C is 90 degrees.

Angle O is given as 45 degrees, so angle A needs to equal:

180 - 90 - 45 = 45 degrees.

Let’s say we want to find the size of a deer population. Suppose that we capture 80 deer, tag them, and release them back into the forest. After some time has passed—allowing the marked deer to thoroughly mix with the rest of the population—we come back and capture another 100 deer. Out of these deer, we find that 20 are already marked. Using this information, what can you estimate the deer population to be?

A. 1,000
B. 400
C. 200
D. 800
E. 600

Answers

Answer:

400

Step-by-step explanation:

20/100 = 80/x

Cross multiply and divide

100 X 80 = 8000 / 20 = 400

The total deer population in the forest will be 400. Then the correct option is B.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Suppose we need to track down the size of a deer populace. Assume that we catch 80 deer, label them, and deliver them back into the timberland. After some time has elapsed - permitting the noticeable deer to completely blend in with the remainder of the populace - we return and catch another 100 deer. Out of these deer, we observe that 20 are as of now checked.

Then the ratio of the number of tag deer to the total deer will be constant. Then the equation is given as,

20 / 100 = 80 / x

x = 80 × (100/20)

x = 400

The total deer population in the forest will be 400. Then the correct option is B.

What is the slope of a line that is perpendicular to the line x=-3?
A.-3
B.0
C.1/3
D.undefined

Answers

Answer:

B. 0

Step-by-step explanation:

The line x = -3 is vertical, thus undefined, because there is no y in the equation. The slope that is perpendicular to an undefined one is 0.

x = 3 is a vertical line.

A line perpendicular to x = 3 is a horizontal line.

A horizontal line has slope = 0.

General formula for a straight line

The general formula for a straight line is ‘y=mx+c'.

But in the equation ‘x = -3’, ‘y' isn't present meaning that the line is independent of ‘y' which is true for a line parallel to the ‘y-axis'. This case can be compared to a generic equation ‘x=a' where a is the distance of the parallel line (to y-axis') from the origin.

This line represents a parallel line to the y-axis which is 3 units left side from the origin.

Now about calculating the slope, we can use the formula ‘m = tan ϴ’

where ‘m' is the slope and ‘ϴ’ is the angle of the line with the X-axis.

Here the value of ϴ is 90° as it is parallel to the y-axis. So the line perpendicular to it will surely have ϴ=0°. Which will be parallel to the

x-axis.

Another method of explaining this can be, for ϴ=90°, m=tan(90),

so m= infinity. if the slope of the line parallel to it is ’n', the relation between the slope of two perpendicular lines is ‘[tex]m*n=-1[/tex]’. Putting the value of ‘m=infinity' we get ‘n=0’.

Now for getting n=0 the angle must be O° as tan(0°)=0 which is nothing but a line parallel to the x-axis.

Therefore, the correct answer is option B.0.

Two cyclists, Alan and Brian, are racing around oval track of length 450m on the same direction simultaneously from the same point. Alan races around the track in 45 seconds before Brian does and overtakes him every 9 minutes. What are their rates, in meters per minute?

Answers

Answer:

Alan: 200 m/min

Brian: 150 m/min

Step-by-step explanation:    

Given : Two cyclists, Alan and Brian, are racing around oval track of length 450m on the same direction simultaneously from the same point. Alan races around the track in 45 seconds before Brian does and overtakes him every 9 minutes.

To find : What are their rates, in meters per minute?

Solution :

Let n represent the number of laps that Alan completes in 9 minutes.

Then n-1 is the number of laps Brian completes.

45 seconds = 3/4 minutes.

The difference in their lap times in minutes per lap is

[tex]\frac{9}{(n -1)}-\frac{9}{n} =\frac{3}{4}[/tex]

Solving the equation we get,

[tex]\frac{9n-9n+9}{n(n -1)} =\frac{3}{4}[/tex]

[tex]9\times 4=3\times n(n -1)[/tex]

[tex]36=3\times n(n -1)[/tex]

[tex]n^2-n-12=0[/tex]

[tex]n^2-4n+3n-12=0[/tex]

[tex]n(n-4)+3(n-4)=0[/tex]

[tex](n-4)(n+3)=0[/tex]

[tex]n=4,-3[/tex]

Neglecting n=-3

So, n=4

Then Alan's speed in m/min is

[tex]S=\frac{D}{T}[/tex]

[tex]S_a=\frac{4\times 450}{9}[/tex]

[tex]S_a=200 m/min[/tex]

Brian completes 3 laps in that 9-minute time, so his rate is

[tex]S_b=\frac{3\times 450}{9}[/tex]

[tex]S_b=150 m/min[/tex]

Therefore, Alan: 200 m/min

Brian: 150 m/min

Determine whether the ffunction X/(x^2-1) is odd even or neither

Answers

equation is:

[tex] f(x) = \frac{x}{ {x}^{2} - 1 } [/tex]

so if its even f(-x) should be equal to f(x)

that means

[tex]f( - x) = \frac{ - x}{ {( - x)}^{2} - 1} \\ \\ f( - x) = - \frac{ x}{ {x}^{2} - 1} [/tex]

so f(x) is not equal to f(-x) so its not even

If its odd than f(-x) should be equal to -f(x)

[tex] - f(x) = - ( \frac{ x}{ { x}^{2} - 1 } ) \\ - f(x) = - \frac{ x}{ {x}^{2} - 1 } [/tex]

so as we can see f(-x)= - f(x)

so the function is odd

Ans:function is odd and not even

Final answer:

By replacing x with -x in the given function X/(x^2-1), we find that it doesn't fulfill the criteria for even or odd functions. Therefore, the function is neither odd nor even.

Explanation:

To determine whether the function X/(x^2-1) is odd, even or neither, you can plug in -x into the function and simplify. For a function to be considered even, f(x) should be equal to f(-x). For a function to be considered odd, f(-x) should be equal to -f(x).

For the given function X/(x^2-1), after replacing x with -x, we get -X/((-x)^2 - 1) which simplifies to -X/(x^2 - 1). Since f(-x) is not equal to f(x) or -f(x), the function is neither odd nor even.

Generally, an even function is symmetrical around the y-axis. That is, if you fold the graph of the function over the y-axis, both halves align. On the other hand, an odd function is symmetric about the origin. That is when the graph is rotated 180 degrees about the origin, the graph remains unchanged.

The equation shows the relationship between x and y: y = −7x + 9 What is the slope of the equation?
A. −7
B. −2
C.7
D. 9

Answers

Answer:

A  (-7)

Step-by-step explanation:

compare y = −7x + 9 to the slope-intercept form of the equation of a straight line:          y = mx + b.

Here -7 corresponds to the slope, m, and 9 corresponds to the y-intercept, b.

The slope of the line represented by y = −7x + 9 is thus A (-7).

Final answer:

The slope of the equation 'y = -7x + 9' is represented by the coefficient of x, which is -7. Thus, the slope of the line is -7.

Explanation:

The equation given is y = -7x + 9. In this equation, -7 is the coefficient of x, and according to the slope-intercept form of a linear equation, which is y = mx + b, the coefficient m represents the slope of the line. Therefore, the slope of the equation y = -7x + 9 is -7.

To confirm, consider that the slope is the amount by which y changes for a unit change in x. So if you were to plot this line, for every one unit increase in x, y would decrease by 7 units, indicating a negative slope. This is consistent with the negative sign in front of the 7 in the equation. Hence, the correct answer is A. -7.
