The point (4, π/6)  can also be represented by the polar coordinates (-4, 7π/6).

We have given that,

a. (-4, 7π/6)

b.(4, 5π/6)

c. (4, -π/6)

d. (-4, 13π/6)

We have to determine the point (4, π/6) that can also be represented by which of the following polar coordinates.

The polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. The reference point is called the pole, and the ray from the pole in the reference direction is the polar axis.

The point (4, π/6)  can also be represented by the polar coordinates (-4, 7π/6).

Final answer:

The point (4, π/6) can also be represented by (-4, 7π/6), utilizing the polar coordinate system's symmetry by extending the radius to the negative side and adding π to the angle.

Explanation:

The point (4, π/6) in Cartesian coordinates corresponds to a point in the first quadrant since the radius is positive and the angle is positive, which is less than π/2. When we want to find an equivalent set of polar coordinates, we can utilize the symmetry of the polar coordinate system.

The point can also be represented by the coordinates (-4, 7π/6) because if you extend the radius to the negative side (so it becomes -4) and add π radians (180 degrees) to the angle, the point ends up in the same location, albeit in the third quadrant. Therefore, the correct answer is a. (-4, 7π/6).

We have been given that a cylinder was enlarged by a scale factor of 4. The new volume is 2,240 cubic units. We are asked to find the volume of original cylinder.

We know that a cylinder is a three dimensional object. Since scale factor is 4, so each side of new cylinder will be 4 times the side of original side of cylinder.

Due to 3 dimensions, the volume of new cylinder is [tex]4^3[/tex] times the volume of original cylinder.

[tex]\text{Volume of original cylinder}\times 4^3=\text{Volume of new cylinder}[/tex]

[tex]\text{Volume of original cylinder}\times 64=2240[/tex]

[tex]\frac{\text{Volume of original cylinder}\times 64}{64}=\frac{2240}{64}[/tex]

[tex]\text{Volume of original cylinder}=35[/tex]

Therefore, the volume of the original cylinder is 35 cubic units.

Answer:

49.13 in

Step-by-step explanation:

circle circumference: 25.13

rectangle perimeter: 24

total: 49.13

The perimeter of the figure to the nearest hundredth. is 28.56 in.

To find the find the perimeter of the figure we'll add the sides of square and the circumference.

Perimeter of figure = 2 × Perimeter of semicircle + 2 × side of square + 2 × side length after excluding semicircle

Radius of semicircle = 4/2 = 2 in.

Perimeter of semicircle

= π r

= 3.14 × 2

= 6.28 in.

Side of square = 6 in.

Side length after excluding semicircle = 6 - 4 = 2 in.

Perimeter of figure

= 2 × Perimeter of semicircle + 2 × side of square + 2 × side length after excluding semicircle

= 2 × 6.28 + 2 × 6 + 2 × 2

= 12.56 + 12 + 4

Answer:

-6 and -10.

Step-by-step explanation:

Added together you get -16, multiplied together results in 60.

The value of two numbers gives multiplied by 60, but added to -16 are - 10 and - 6.

Given that,

The multiplication of two numbers is 60

And, the addition of two numbers is - 16.

Let us assume that the two numbers are x and y.

Hence we get;

[tex]x y = 60[/tex]  ... (i)

And, [tex]x + y = - 16[/tex]  .. (ii)

From equation (ii);

[tex]y = - 16 - x[/tex]

Substitute the above values in (i);

[tex]x (- 16 - x) = 60[/tex]

[tex]- 16x - x^2 = 60[/tex]

[tex]x^2 + 16x + 60 = 0[/tex]

[tex]x^2 + (10 + 6)x + 60 = 0[/tex]

[tex]x^2 + 10x + 6x + 60 = 0[/tex]

[tex]x(x + 10) + 6 (x + 10) = 0[/tex]

[tex](x + 10) (x + 6) =0[/tex]

This gives two solutions,

[tex]x = - 10[/tex]

[tex]x = - 6[/tex]

Substitute x = - 10 in (ii);

[tex]x + y = - 16[/tex]

[tex]- 10 + y = - 16\\y = - 16 + 10\\y = - 6[/tex]

Substitute x = - 6 in (ii);

[tex]x + y = - 16[/tex]

[tex]-6 + y = - 16\\y = - 16 + 6\\y = - 10[/tex]

Therefore, both the numbers are - 10 and - 6.

Answer:

The slope is -3 and the y intercept is -2

Step-by-step explanation:

y +3x = -2

We want this in slope intercept form

y = mx+b where m is the slope and b is the y intercept

Subtract 3x from each side

y +3x-3x = -3x-2

y = -3x-2

The slope is -3 and the y intercept is -2

Answer:

the slope is -3 and the y intercept is -2

Step-by-step explanation:

y+3x=-2

you want to transform the equation into slope intercept form: y= mx+b

subtract 3x from both sides

y= -3x-2

Answer:

40 cm

Step-by-step explanation:

a square has 4 equal length sides, to get area you multiply two of those sides, 10 x 10 = 100, so each side is 10cm long, adding all of the sides together gets you 40cm.

Answer:

40cm

Step-by-step explanation:

We know that the formula for area of a square is side length squared or [tex]s^2[/tex]

In this case, [tex]s^2=100[/tex]. So we can go through the following steps in order to solve for s

[tex]s^2=100\\\sqrt{s^2} =\sqrt{100} \\\\s=10[/tex]

If one side equals 10, and we know all squares have 4 equal sides, then we can multiple 10 * 4 or add 10+ 10 + 10 + 10.

Our outcome is 40!

Answer:

Greg pays more interest than Linda

He pays $17.45 more

Step-by-step explanation:

Greg

P=$1975

R=5%=0.05

Answer:

The volume of the prism is 476 cm^3

Step-by-step explanation:

Mathematically, the volume of a right prism can be calculated using the formula area of the base * height of the prism

Here, the base is a parallelogram and thus, the area of the base can be calculated using the formula A = bh where b is the parallelogram base and h is the height

in the question the parallelogram has a base of 8.5cm with the height at that point as 4cm

The area of that parallelogram is thus 4 * 8.5 = 34 cm^2

the volume of the right pyramid is thus 34 * 14 = 476 cm^3

Answer:

Length of area is 857.14 ft

Width of area is 857.14 ft

Length of dividing fence is 857.14 ft

Step-by-step explanation:

Here we have

Area of rectangle = Length × Width

The dimension, of the rectangle with the largest area is the dimension of a square, hence we have;

Length of rectangle = Width of rectangle = x

Hence,  the perimeter of the area = 4·x, while the width of the dividing fence = x

Therefore, since the we have;

Cost of the perimeter fence = $15/foot

Cost of the dividing fence = $10/foot

Then;

4·x × 15 + x × 10 = 60000

60·x + 10·x = 60000

x = 60000/70 = 857.14 ft

Which gives the following dimensions;

Length of area = 857.14 ft

Width of area = 857.14 ft

Length of dividing fence = 857.14 ft.

Answer: 9 weeks

Step-by-step explanation:

First, we would have to set up an equation.

468 - 9w = 18 + 66w

The variable w stands for weeks.

We need to figure out when their bank account will become equal.

So, we need to solve for w.

First, let’s combine like terms. I will move 9w to the other side.

468 = 18 + 66w + 9w

Then simplify:

464 = 18 + 55w

Then, do the same as you did before, just move the 18 to the other side. Keep in mind that when a number switches sides, it’s switches signs (from negative to positive or positive to negative)

464 + 18 = 55w

482 = 55w

To isolate the variable, you would have to divided 55w by 55. Keep in mind, what you do to one side of an equation you must do to the other.

482/55 = 55w/55

8.76 = w

When you round to the nearest whole number, it will be 9 weeks.

Therefore, it will take 9 weeks for them to have the same amount of money in the bank.

Answer:

The z-score of a teenage with waist size 33 inch is 2

Step-by-step explanation:

Mathematically, the z-score can be calculated using the formula;

z-score = (x- mean)/SD

where mean = 29 inches , SD = 2 inches and x = 33 inch

Plugging these values, we have

z-score = (33-29)/2 = 4/2 = 2

The z-score of a teenage male with a33 inch waist is 2.

Given that,

Based on the above information, the calculation is as follows:

[tex]= (33-29)\div 2 \\\\= 4\div 2[/tex]

= 2

Therefore we can conclude that The z-score of a teenage male with a33 inch waist is 2.
