Answer:

\(y = \frac{29}{5} x \\ \frac{y}{x} = \frac{29}{5} \)

Answer:

(2, 60°)

Step-by-step explanation:

A point in polar form (a,b) is represented by a radius and an angle (r, ϴ). To convert, use the formula r² = a² + b² to get r, and  \(tan^{-1}\)(b/a) = ϴ

\(r = \sqrt{1^{2} + \sqrt{3} ^{2} }\)

\(r = \sqrt{1+3}\)

\(r = \sqrt{4}\)

= 2

\(tan^{-1}\)(\(\sqrt{3}\)/1) = ϴ

= 60°

Answer:

See explanation

Step-by-step explanation:

In this question, you are given a table with x and y points.

If you convert those values into coordinate points (x, y) you'll get the following points:

(4, 3) (2, 6) (5, 0)

A coordinate point is (x, y) meaning you should find the first value on the x-axis (horizontal axis) and move up y units.

Or, you can also find the y value on the y-axis (vertical axis) and move left x units.

For example, for (4, 3) you should find 4 on the x-axis, and move up 3 units.

For (2, 6) you should find 2 on the x-axis, and move up 6 units.

For (5, 0) you should find 5 on the x-axis, and move up 0 units.

Hope that makes sense, let me know if you have any questions.

I have also attached the points graphed on a graphing calculator to avoid any confusion.

Answer:

9 cm^2

Step-by-step explanation:

The area of a triangle is calculated with the following formula:

1/2*b*h (b: base, h: height)

The base is given as 3 and height is 6 so

1/2*3*6 = 9 cm^2 is the answer we are looking for.

In this case, we must employ the combination as well as repetition formula.

C(n + r-1, r) = (n + r -1)!/ r! (n - 1) !

n = 10 is provided (The number of questions)

Every question is worth a minimum of 5 points.

For 10 question = 10×5 = 50 points.

The total are 100 (sum of the scores)

r = 100 - 50

r = 50

Applying the formula.

C(10 + 50 - 1 , 50) = (10 + 50 - 1)!/ 501 (10 - 1)!

C(59, 50) = 59!/50!9!

We get by clarifying the above factorial.

C(59, 50) = 12,565,671,261

Thus, there are 12,565,671,261 ways to assign scores to the problems in discrete mathematics exam.

Answer:

b = 12

Step-by-step explanation:

To do this, we simply just divide both sides by 1/3. When we do so, we find our answer to be 12.

Answer:

b=12

Step-by-step explanation:

To solve this equation, we need to get b isolated on one side of the equation. Perform the inverse operation to both sides of the equation.

1/3b=4

1/3 and b are being multiplied (1/3 * b=1/3b). The inverse of multiplication is division. Divide both sides by 1/3.

1/3b / 1/3= 4/ 1/3

When dividing by a fraction, you can multiply by the reciprocal of the fraction. To find the reciprocal, flip the numerator (top number) and denominator (bottom number).

1/3--> 3/1=3

3*1/3b= 4*3

b=4*3

b=12

Let's check our solution. Substitute 12 in for b in the original equation.

1/3b=4

1/3*12=4

4=4

The statement above is true, so we know our solution is correct.

Answer:

-1/5

Step-by-step explanation:

First:

Calculate the rise:

On this graph we go down 1 meaning our rise will be -1.

Second:

Calculate the run:

On the graph we go right 5 so the run would be 5.

Third:

We put the rise and run together to get the slope.

Hence, the answer is -1/5

Notes:

Rise means how many units you move up or down from point to point.

Run means how far left or right you move from point to point.

Up and Right= + outcome

Down and Left= - outcome

Also if your rise over run is the same number but two negative number the slope would turn into a positive.

Example:

-5/-5=1

Based on the given information, it seems that the number of left-handed desks in each classroom is adequate.

Based on the given information, we can calculate the expected number of left-handed students in a classroom:

Expected number of left-handed students = (total number of students in a classroom) x (proportion of left-handed students in the population)

Expected number of left-handed students = 30 x 0.11

Expected number of left-handed students = 3.3

Since each classroom contains four left-handed desks, it seems that the number of left-handed desks is more than enough to accommodate the expected number of left-handed students. In fact, there may even be some unused left-handed desks in each classroom.

Therefore, based on the given information, it seems that the number of left-handed desks in each classroom is adequate.

Answer:

\( \large \boxed{f(8) = 27}\)

Step-by-step explanation:

Goal

Given

\(f(x) = \frac{1}{2} {x}^{2} - ( \frac{1}{4} x + 3)\)

Step 1

\(f(8) = \frac{1}{2} {(8)}^{2} - ( \frac{1}{4} (8) + 3)\)

Step 2

\(f(8) = \frac{1}{2} (64) - ( \frac{8}{4} + 3) \\ f(8) = 32 - ( \frac{2}{1} + 3) \\ f(8) = 32 - (2 + 3) \\ f(8) = 32 - (5) \longrightarrow 32 - 5 \\ f(8) = 27\)

Hence, the value of f(8) is 27.

Practice A. 7.4. For use with pages 457-464. Find the value of x. Write your answer in simplest radical form. 2. هل. 45°457 ... Find the value of each variable.

Answer:

y = 3x - 7

Step-by-step explanation:

Slope-intercept form:

y = mx + b

Where:

y is the y value.

m is the slope.

x is the x value.

And b is the y-intercept.

First, you want to find your slope. To do this, you can either use the slope formula to find the slope, or just count on the picture:

m = rise/run

m = 3/1

m = 3

With the slope formula, you first need to choose two points.

I chose:

(2, -1) and (3, 2)

Slope formula:

m = (y2 - y1) / (x2 - x1) {It doesn't matter which point you choose to be x2 and x1, just be consistent when you plug it into the formula}

m = (2 - (-1)) / (3 - 2)

m = 3/1

m = 3

Now that you have your slope, all you need is your y-intercept. To find your y-intercept, you can either look at the graph (again) to see where the line intersects with the y-axis, or you can solve it algebraically:

y-int = -7

To solve algebraically, choose a random point on the line and plug it into what you have for your equation so far and then solve for b.

I chose:

(2, -1)

y = 3x + b

-1 = 3(2) + b

-1 = 6 + b

-1 - 6 = b

b = -7

Now you have your final answer:

y = 3x - 7

You have the following function:

In order to determine the intervals, it is necessary to calculate the first derivative of the function, equal it to zero, and identify the zeros of the equation, just as follow:

the zeros of the previous equation are:

Next, it is necessry if the previous values are minima or maxima. Evaluate the second derivative for the previous values of x. If the result is greater than 0, then, it is a minimum. If the result is lower than zero, it is a maximum:

Then, for x=0 there is a maximum, and for x=-√3 and x=√3 there is a minimum.

Hence, until x = -√3 the function decreases. In between x=-√3 and x=0 the function increases. In between x=0 and x=√3 the function decreases and from x=√3 the function increases.

Furthermore, it is necessary to find the inflection points. Equal the second derivative to zero and solve for x:

then for x=1 and x=-1 there are inflection points.

The interval where the function is concave up is:

(-∞ , -1) U (1, ∞)

The interval where the function is concave down is:

(-1,1)

The rate of change of the volume of the cone at the given instant is 1 238 768 66.67 cm^3/s.

The volume of a cone can be calculated using the formula V = (πr^2h)/3, where r is the radius and h is the height of the cone.

At the given instant, radius = 8 88 cm and height = 10 1010 cm.

Substituting these values in the formula we get,

\(V = (π(8 88 cm)^2(10 1010 cm))/3 = 2 477 537 33.33 cm^3\)

The rate of change of the volume of the cone at that instant can be calculated as follows:

Let dV/dt be the rate of change of the volume at that instant.

\(dV/dt = (dV/dr)*(dr/dt) + (dV/dh)*(dh/dt) \\dr/dt = 3 33 cm/s \\dh/dt = -4 44 cm/s\)

Differentiating the volume of a cone formula with respect to r and h, we get

\(dV/dr = (πr^2h) dV/dh = (πr^2h)/3\)

Substituting these values in the equation for dV/dt, we get

\(dV/dt = (π(8 88 cm)^2(10 1010 cm)) + (π(8 88 cm)^2(10 1010 cm))/3 * (-4 44 cm/s) = 1 238 768 66.67 cm^3/s\)

Therefore, the rate of change of the volume of the cone at the given instant is \(1 238 768 66.67 cm^3/s\).
