Step-by-step explanation:

-210 degrees in standard position corresponds to an angle in the 3rd quadrant  30 degrees below the negative x-axis

The hypotenuse of the triangle here is 1, and we want the coordinates.

_______________________(0,0)

|(x = -root(3)/2)

| (y = -1/2)

The coordinates of the point at which the terminal side intersects the unit circle are (-√3/2, -1/2).

The cartesian plane is a two-dimensional coordinate plane that is formed when two parallel lines meet. The X-axis is the horizontal line, and the Y-axis is the vertical line. On the Cartesian plane, the coordinate point (x, y) indicates that the point is on the right of the origin if the sign of x is positive; otherwise, the point is on the left of the origin.

Given  -210 degrees is in standard position,

-210° lies in the third quadrant,

which is 180° + 30° or π + 30°

the coordinate are x = cos(π + 30°)

and y = sin(π + 30°)

cos(π + Ф) = -cosФ and

sin(π + Ф)  = -sinФ

x = cos(π + 30°) = -cos30° = -√3/2

y = sin(π + 30°) = -sin30° = -1/2

Hence the coordinates of points are (-√3/2, -1/2).

Answer: it will take the faster computer 15 minutes to do the job on its own.

Step-by-step explanation:

Let t represent the number of minutes it will take the faster computer to do the job on its own. It means that the rate at which it does the job per minute is 1/t

If it takes the slower computer 30 minutes to do the job on its own. It means that the rate at which it does the job on its own per minute is 1/30

By working together, they would work simultaneously and their individual rates are additive. Working together it takes two computers 10 minutes to send out a company's email. It means that the rate at which both computers work together per minute is 1/10 Therefore,

1/t + 1/30 = 1/10

Cross multiplying by 30x, it becomes

3x = x + 30

3x - x = 30

2x = 30

x = 30/2

8 people went to the game.

Step-by-step explanation:

Let x represent number of tickets.

We have been given that the family parked the car in a parking lot which charged ​$20. The cost per ticket was ​$27.

The cost of x tickets would be [tex]27x[/tex].

The total cost of going to baseball game would be equal to cost x tickets plus parking cost that is [tex]27x+20[/tex].

where π = 3.14

r = radius

From the question, we've been given the radius as 10cm. So, we plug the radius into the formula.

Area= πr^2

= 3.14 × (10 × 10)

= 3.14 × 100

= 314 cm

Answer:

Step-by-step explanation:

Given a composite figure,

A circle of radius r = 10cm

We want to find the area of the circle?

Area of a circle is calculated using

A = πr²

Answer: it is c. 10.7 cm

Rounded to the nearest tenth, the length of CD is approximately 5.8 cm.

To find the length of CD in a right triangle ABC where:

BA = 10 cm (the side adjacent to angle B)

angle B = 30 degrees

angle C = 90 degrees (a right angle)

angle D = 25 degrees

We can use the trigonometric ratio for tangent (tan) since we know the measure of angle B and the length of side BA. The tangent of an angle in a right triangle is the ratio of the length of the side opposite to the angle to the length of the side adjacent to the angle.

In this case, we want to find CD, which is the side opposite to angle B. So, we can use the following relationship:

tan(B) = CD / BA

First, find the tangent of angle B (30 degrees):

tan(30 degrees) ≈ 0.5774 (rounded to four decimal places)

Now, we can solve for CD:

CD = tan(B) * BA

CD ≈ 0.5774 * 10 cm

CD ≈ 5.774 cm

Rounded to the nearest tenth, the length of CD is approximately 5.8 cm.

Answer:

The angular velocity of the wheel in radians per minute is 96·π·rad/min

Where π = 22/7 then the angular velocity is [tex]301\frac{5}{7} \ rad/min[/tex]

Step-by-step explanation:

The number of revolutions completed per 3 seconds = 2.4 revolutions

∴ The number of revolutions completed per second = 2.4/3 = 0.8 = 4/5 revolutions

The angle per revolution = 2π radians

∴ Angular velocity per second = 0.8×2×π rad/sec

The angular velocity of the wheel in radian per second = 1.6·π·rad/sec

1 minute = 60 Seconds

∴The angular velocity of the wheel in radians per minute = 96·π·rad/minute

Where π = 22/7 then the angular velocity = [tex]301\frac{5}{7} \ rad/min[/tex].

Step-by-step explanation:

Final answer:

Using the recursive relationship f(n) = -5f(n-1) - n, we calculated the values step by step to find that f(4) is -914.

Explanation:

The question asks us to find the value of f(4) given that f(1) = 7 and the recursive relationship f(n) = -5f(n-1) - n.

To find f(4), we need to compute it in a step-by-step manner by first finding f(2) and f(3), and using those results to finally compute f(4).

Starting with f(1) = 7, we calculate f(2):

f(2) = -5f(1) - 2 = -5*7 - 2 = -35 - 2 = -37.

Next, calculate f(3):

f(3) = -5f(2) - 3 = -5*(-37) - 3 = 185 - 3 = 182.

Finally, calculate f(4):

f(4) = -5f(3) - 4 = -5*182 - 4 = -910 - 4 = -914.

Therefore, the value of f(4) is -914.

Final answer:

Using the recursive function given, by computing step by step from f(1) up to f(4), we find that f(4) equals -914.

Explanation:

To find the value of f(4), we must use the given recursive relation f(n) = -5f(n-1) - n, starting with the base case f(1) = 7.

Therefore, f(4) = -914.

The inequality that represents Max's situation with renting a bicycle is 5 + 3h <= 20. Max can rent the bicycle for up to 5 hours with his $20 budget, and renting for 4 hours would satisfy the inequality.

The inequality to represent Max's situation with renting a bicycle, considering his budget constraints, would be:

5 + 3h \<= 20

Where h represents the number of hours Max can rent the bike. To solve for h, you subtract 5 from both sides of the inequality (which represents the fixed insurance fee) and then divide by 3 (the hourly rate for renting the bike):

3h \<= 15

h \<= 5

Thus, Max can rent the bicycle for up to 5 hours to stay within his budget of $20. An example value that satisfies this inequality is 4 hours, which would cost Max $5 for insurance plus $12 for the rental time, totaling $17.

Answer:

The length of line segment QP is 20 units ⇒ 4th answer

Step-by-step explanation:

If a secant and a tangent are drawn from a point outside the circle, then the product of the lengths of the secant and its external segment equals the square of the length of the tangent segment

Look to the attached figure

∵ PQ is a tangent to the circle

∵ PM is a secant intersects the circle at points N and M

- That means the product of the lengths of PM and PN is

   equal to the square of the length of PQ

∴ (PQ)² = (PN). (PM)

∵ The length of Q P is n units

∴ PQ = n

∵ The length of N P is 11.5 units

∴ NP 11.5

∵ The length of M N is 24 units

∴ MN = 24

- The length of the secant PM is the sum of the lengths of PN

   and MN

∵ PM = PN+ NM

∴ PM = 11.5 + 24 = 35.5

Substitute the values of PQ, PN, and PM in the formula above

∵ n² = 11.5 × 35.5

∴ n² = 408.25

- Take √  for both sides

∴ n = 20.205197

- Round it to the nearest unit

∴ n = 20

∵ n is the length of PQ

∴ The length of line segment QP is 20 units

Final answer:

The actual distance between Madison and Franklin is 42 miles.

Explanation:

To find the actual distance between Madison and Franklin, we can use the given scale of 1 in: 7 mi. Since Madison and Franklin are 6 inches apart on the map, we can multiply the scale by the number of inches to find the distance in miles.

Distance in miles = Scale x Number of inches apart = 7 mi/in x 6 in = 42 miles

Therefore, the actual distance between Madison and Franklin is 42 miles.

Answer:

If all the 300 students were surveyed, 220 would have been in favor of the photo booth.

Step-by-step explanation:

Sample size = 15

People out of 15 in favor of photo booth = 11

Percentage of people in favor of school dance = [tex]\frac{11}{15} \times 100\% = 73\frac{1}{3} \%[/tex]

We have to find if all 300 students are surveyed how many will be in favor of photo booth. Remember that, the sample data is the best estimator of the population data. So, the sample data of 15 students will be the best estimator for the entire population of 300 students.

Since, in the sample of 15 students, [tex]73\frac{1}{3} \%[/tex] were in favor of photo booth, we would expect that if all the 300 students were surveyed, the same percentage will be in favor of photo booth. So we need to calculate [tex]73\frac{1}{3} \%[/tex] of 300.

[tex]73\frac{1}{3} \% \text{ of 300}\\\\ = 73\frac{1}{3} \% \times 300\\\\ =\frac{220}{3} \% \times 300\\\\ =\frac{220}{300} \times 300\\\\ = 220[/tex]

This means if all the 300 students were surveyed, 220 would have been in favor of the photo booth as per the sample data.

Approximately 220 out of 300 students are likely to be in favor of the photo booth.

To determine how many of the 300 students are likely to be in favor of the photo booth, we can use the proportion given by the sample.

1. Calculate the proportion of students in favor from the sample:

Proportion = Number in favor / Total surveyed = 11 / 15

Proportion = 0.7333 (rounded to four decimal places)

2. Apply this proportion to the entire school population:

Expected number in favor = Proportion × Total school population

Expected number in favor = 0.7333 × 300

Expected number in favor ≈ 220

Therefore, out of 300 students, approximately 220 students are likely to be in favor of the photo booth.

Step-by-step explanation:

6 and 4 force H to be the largest and G to be the smallest.

For any right triangle, the 90 degree angle is always the largest. The longest side of a triangle is always opposite the largest angle. Similarly, the shortest side of a triangle is always opposite the smallest angle.

Angle G is opposite side HI = 4 which is the smallest side, so angle G is the smallest angle.

Angle H is the middle angle as this is the longer leg, but it is not longer than the hypotenuse. The hypotenuse is always the longest side.
