Step-by-step explanation:

The distance between the two points (3, π/6) and (2, π/3) in polar coordinates is 1.614 units

The points are (3, π/6) and (2, π/3)

The polar coordinate system is the system that represent a point by a distance from a fixed reference point and angles from a reference direction

The distance between the two points

d = [tex]\sqrt{r_1^2+r_2^2-2r_1r_2cos(theta_1-theta_2)}[/tex]

(3, π/6) is the coordinates of first point

(2, π/3) is the coordinates of second point

Substitute the values in the equation

d = [tex]\sqrt{3^2+2^2-2(3)(2)cos(\pi/6 - \pi /3)}[/tex]

d = [tex]\sqrt{9+4-12(\frac{\sqrt{3} }{2} )}[/tex]

d = [tex]\sqrt{13-6\sqrt{3} }[/tex]

d = 1.614 units

Hence, the distance between the two points (3, π/6) and (2, π/3) in polar coordinates is 1.614 units

Answer:

OB. g(x) = 31x1

C. g(x) = 13x1

Step-by-step explanation:

The function notation of the following are:

f(1) = 5

f(0) = 1

f(-3) = -11

f(8) = 33

Given:

x is the input.

the function is 4x+1

f(x) is the output.

we are asked to determine the values of the following :

a. f(1)

x = 1

so f(x) = 4x+1

f(1) = 4(1)+1

f(1) = 4+1

f(1)=5

b. f(0)

x = 0

so f(x) = 4x+1

f(0) = 4(0)+1

f(0) = 0+1

f(0)=1

c. f(-3)

x = -3

so f(x) = 4x+1

f(-3) = 4(-3)+1

f(1) = -12+1

f(1)= -11

d. f(8)

x = 8

so f(x) = 4x+1

f(8) = 4(8)+1

f(8) = 32+1

f(1)=33

Hence we get the required values.

The required feet added to both the length and width of the patio is 6 feet.

Given that,
A square patio had the same number of feet added to its length and width. The equation A(x) = x² + 12x + 36 represents the area of the new patio in square feet, where 'x' was the length and width of the original patio, in feet.

Here,

According to the question,
A(x) = x² + 12x + 36
A(x) = x² + 6x + 6x + 36
A(x) = (x + 6)(x + 6)

Answer:

j = 9

Step-by-step explanation:

Let's solve for the value of j,

→ -3(j − 8) + (-6) = -9

→ -3j + 24 - 6 = -9

→ -3j + 18 = -9

The question is incorrect.

The arc length of the segment it 6.28 meters

From the question, we have the following parameters:

Central angle, x = 72 degrees

Diameter, d = 10 centimeters

The radius of the circle can be calculated using

r = d/2

So, we have

r = 10/2

Evaluate

r = 5 cm

The exact arc length using the central angle measure is calculated as:

Arc length = x/360 * 2πr

Substitute the known values in the above equation

Arc length = 72/360 * 2π * 5

Evaluate

Arc length = 6.28

Hence, the exact arc length using the central angle measure is 6.28 meters

Answer:

the number greater than 5 is only 6 in the case of a coin.

Step-by-step explanation:

in a coin numbers greater than 5 is only 6

probability= No of required outcome/ No of possible outcome.

P.B= 1/6

in a coin there is head or tail

P.B of getting tail

P.B= Tail/Head + Tail

P.B= 1/2

The coin of course, has two sides, heads and tails. Assume we are talking about a six-sided die. Let's look at the individual probabilities.

There are only two sides to the coin, tails being one of them, so:
p(tails) = 1/2

The die goes from 1 to 6. We need to see the numbers that fit the inequality:

p(5 < x ≤ 6)
There is only one integer that is greater than five and less than or equal to six, and that is six. If there is only one number out of six, then:
p(>5) = 1/6

When dealing with probabilities, to determine the probability of two things happening, multiply both probabilities.

1/2 x 1/6 = 1/12

Toss     Dollars

30           12

45           18

See image in the attachment that shows the points on a coordinate plane.

The ratios that give the same value when we compare them together are regarded as equivalent ratios.

For example, 2:3 is an equivalent ratio to 4:6, because 4/6 can be simplified as 2/3.

If it cost $12 to toss 30 rings, the ratio of dollars to number of toss would be: 12:30 = 2:5.

Let x = number of toss

Let y = amount in dollars

The equation that models the equivalent ratios can be written as y = 2/5x.

Therefore, when we have 2 dollars (y = 2):

2 = 2/5(x)

10 = 2x

10/2 = x

x = 5 toss

When we have 45 tosses (x = 45):

y = 2/5(45)

y = 18 dollars

The product of linear factors for f(x) is given as (x + 1)(x² + 4x + 2) for -1 as a zero of the polynomial x³ + 5x² + 6x + 2.

The factor theorem states that;

f(x) is divisible by x - a if and only if f(a) = 0

f(x) is divisible by x + a if and only if f(-a) = 0

in both cases, a and -a are the zeros of the polynomials.

From the question, given that -1 is a zero of

f(x) = x³ + 5x² + 6x + 2, then it is divisible by x + 1 and f(-1) = 0.

Dividing x³ + 5x² + 6x + 2 by x + 1 using the long division will result to another factor x² + 4x + 2 with a remainder of zero. (complete long division is attached as a photo!)

Therefore we can then conclude that (x + 1)(x² + 4x - 2) is the product of linear factors for f(x) = x³ + 5x² + 6x + 2 and -1 as a zero.

The penguin's depth after 4 minutes is d = 10.7 + 146m

A rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate. The word "per" can be further replaced by the symbol "/" in problems.

if the penguin moves with a speed of 146 meters per minute, then its distance after m minutes is  = 146 x m

Since it moved from an elevation 10.7 below the sea surface, its total distance(d) would be = 10.7 + 146m

substitute m = 4 minutes,

we have

d  = 10.7 + 146(4)

d = 594.7metres

If the picture is the point (-7, -9)

Detailed explanation:

When the point (x, y) rotates 90 degrees counterclockwise with respect to the origin, its image is (-y, x)

When the point (x, y) rotates 180 degrees counterclockwise around the origin, its image is (-x, -y)

The picture of the point (x, y) if it were rotated 270 degrees counterclockwise with respect to the origin is (y, -x)

The highlighted point is (9, -7)
