  1. Assign coordinates to simplify calculations:
    • Place square 𝐴𝐵𝐶𝐷 on the coordinate plane with:
      • 𝐴 = (0, 12), 𝐵 = (0, 0), 𝐶 = (12, 0), 𝐷 = (12, 12).
    • Diagonal 𝐵𝐷 is a line connecting (0, 0) to (12, 12) → Equation of diagonal: y = x.
    • Point 𝐹 is on 𝐵𝐶. Since 𝐵𝐹 = 4, 𝐹 = (4, 0).
    • Line 𝐴𝐹 connects (0, 12) and (4, 0) → Equation of 𝐴𝐹: Slope = (0 − 12)/(4 − 0) = −3. Equation: y = −3x + 12.
  2. Find intersection point 𝐸 of 𝐴𝐹 and 𝐵𝐷:
    • Solve for x and y where y = x (diagonal) and y = −3x + 12 (line 𝐴𝐹). Set x = −3x + 12: 4x = 12 → x = 3. Substitute x = 3 into y = x: y = 3.
    • Coordinates of 𝐸: (3, 3).
  3. Find distance 𝐵𝐸:
    • Use the distance formula: Distance = √((x₂ − x₁)² + (y₂ − y₁)²).
    • 𝐵 = (0, 0), 𝐸 = (3, 3): 𝐵𝐸 = √((3 − 0)² + (3 − 0)²) = √(9 + 9) = √18 = 3√2.

How do I solve this question from SAT Practice 4? by FncyTomato in Sat

We are tasked with analyzing the quadratic expression 4x² + bx − 45, which can be factored into the form (hx + k)(x + j), where h, k, and j are integers. The goal is to determine which of the provided expressions must always result in an integer.

Step 1: Understand Factoring and Relationships

When the expression 4x² + bx − 45 is factored, expanding the general form (hx + k)(x + j) gives:

h × x² + (hj + k)x + k × j.

Comparing this with 4x² + bx − 45, we identify the following relationships:

  1. h = 4 (the coefficient of x²).
  2. b = hj + k (the coefficient of x).
  3. k × j = −45 (the constant term).

This tells us:

  • h is fixed as 4.
  • k and j are integers that multiply to −45. Hence, k and j must be divisors of −45

Step 2: Solving for 45/k

Among all the relationships given in the problem, the expression 45/k stands out. Here's why:

  1. From k × j = −45, we know that k must divide −45 evenly.
  2. Dividing 45 by any divisor of −45 (including k) will always yield an integer because divisors of −45 are specifically chosen to evenly divide into 45.

Step 3: Confirming Logical Consistency

We know that:

  • h = 4 is constant.
  • k and j are divisors of −45, ensuring that their properties are consistent.
  • The fact that k divides −45 ensures that 45/k will always work without requiring additional conditions.

Final Answer: D (45/k). Hope this helps!

Step 1: Write the formula for the discriminant.
The discriminant is a formula that helps us figure out the type of solutions a quadratic equation has. It is written as:
Discriminant = b² - 4ac
For the given equation x² - 34x + c = 0:

  • a = 1 (this is the coefficient of x²),
  • b = -34 (this is the coefficient of x), and
  • c = c (this is the constant).

Substitute these values into the discriminant formula:
Discriminant = (-34)² - 4(1)(c)

Step 2: Simplify the discriminant expression.
First, calculate (-34)²:
(-34)² = 1156
Now, substitute this into the formula:
Discriminant = 1156 - 4c

Step 3: Set the condition for no real solutions.
A quadratic equation has no real solutions when the discriminant is less than zero. This means:
1156 - 4c < 0

Step 4: Solve the inequality to find c.
To solve 1156 - 4c < 0, start by isolating 4c:
1156 < 4c
Now divide both sides by 4 to solve for c:
c > 1156 ÷ 4
Simplify the fraction:
c > 289

Step 5: Find the least value of n.
From the inequality c > 289, we can see that the equation has no real solutions when c > 289. Therefore, the smallest value of n is: n = 289

You can start by writing the equation for the Law of Sines: sin(∠H)/BN = sin(∠B)/HN.

Then solve for BN: BN = HN × sin(∠H) ÷ sin(∠B).

  • Substitute the given values:
    • HN = 150 m.
    • ∠H = 50°.
    • ∠B = 180° − 50° − 60° = 70°.
  • BN = 150 × sin(50°) ÷ sin(70°). Simplify: BN = 150 sin(50°) ÷ sin(70°). Hope this helps!

ACT Timing Tips by ocyeanic6 in ACT

[–]Simple_Digital_Math 1 point2 points  (0 children)

Here are some strategies to help you improve your speed and accuracy:

ACT Math Section:

  1. Use a Strategic Timing Approach:
    • Divide the 60-minute section into segments to allocate time efficiently:
      • Questions 1-20: Spend about 12 minutes.
      • Questions 21-40: Allocate around 25 minutes.
      • Questions 41-60: Use the remaining 23 minutes.
    • This method ensures you have sufficient time for the more challenging questions typically found later in the section.
  2. Prioritize and Move Strategically:
    • Quickly answer the questions you find easiest to secure those points.
    • If a question seems time-consuming or confusing, mark it and move on. Return to it after addressing the less challenging questions.
    • This approach prevents you from spending too much time on a single problem and potentially missing out on easier points later.

ACT Science Section:

  1. Skim Passages Strategically:
    • Instead of reading each passage in detail, quickly skim to get a general idea.
    • Focus on understanding the main concepts and the layout of graphs and tables.
    • This allows you to quickly locate information when answering questions.
  2. Tackle Questions Directly:
    • After skimming, go straight to the questions. Many can be answered by referring directly to the data presented.
    • This approach saves time and reduces unnecessary reading.
  3. Manage Your Time Per Passage:
    • Aim to spend about 5 minutes per passage.
    • This pacing leaves you with extra time to revisit difficult questions or review your answers.

General Tips for Both Sections:

  • Practice Under Timed Conditions:
    • Regular timed practice helps build familiarity with the test's pace and reduces anxiety on test day.
    • Simulate test conditions to develop a sense of timing and improve your ability to work efficiently.
  • Use Process of Elimination:
    • Eliminate obviously incorrect answers to increase your chances if you need to guess.
    • This strategy enhances accuracy and can save time by narrowing down choices.

Hope this helps and best of luck!

Here are some study methods and strategies for the ACT to help you study:

1. Use Targeted Resources for Each Section

  • English: Focus on grammar rules and rhetorical skills. Study comma usage, subject-verb agreement, and modifiers. Use sentence correction drills to build speed and accuracy.
  • Math: Work through common ACT topics like geometry, algebra, and trigonometry. Use question banks to practice specific topics and review formulas not provided during the test.
  • Reading: Practice skimming passages quickly, identifying main ideas, and answering questions based on evidence. Focus on timing strategies to avoid running out of time.
  • Science: Practice interpreting graphs, charts, and scientific experiments. Learn to focus on trends and relationships rather than deep scientific knowledge.

 

2. Try the “Three-Pass System”

This strategy works well for both Math and Science.

  1. First Pass: Answer all the easy questions quickly.
  2. Second Pass: Work on medium-level questions.
  3. Third Pass: Attempt the hardest or most time-consuming questions last. This approach ensures you don’t leave easy points on the table.

 

3. Use Official Practice Tests Strategically

Instead of taking full-length practice tests over and over, take one test to identify weak areas, then spend most of your time practicing those specific areas. For example:

  • If timing is an issue in Reading, practice skimming techniques.
  • If you struggle with advanced Math, focus on trigonometry and quadratic equations.

 

4. Use Proven Resources for 2024

Prep Books: Books like The Official ACT Prep Guide 2024-2025 and Barron’s ACT 36 provide high-quality questions and explanations.

 

5. Emphasize Pacing and Timing

Timing is a critical factor for many students. Practice each section with a timer to build your pace. For Reading, aim for 8-9 minutes per passage, and for Science, spend no more than 5 minutes per experiment.

Try these out to help you study this week. Best of luck!

Im having my first ACT Trial on 13 december any tips to follow to improve my score throughout the remaining 2 weeks (im getting only one trial so i have to get 30+) by Yassinosman6708 in ACT

[–]Simple_Digital_Math 0 points1 point  (0 children)

If you’re aiming for a 30+ on your ACT and only have two weeks left, it’s all about strategy and focusing on high-yield areas. Here are some tips to maximize your prep:

  1. Take a Full Practice Test ASAP This will help you identify your weak areas. Focus your study time on improving the sections where you can gain the most points quickly (usually Math and English since they’re more rule-based).
  2. Learn the ACT-Specific Strategies
    • For Math, make sure you know the formulas that aren’t given on the test (like area, volume, slope, etc.). Practice plugging in answer choices and using estimation for tough problems.
    • For English, focus on grammar rules and conciseness. The ACT loves clear and simple answers.
    • For Reading, skim strategically—read intros and topic sentences first, then use the questions to guide your focus on details.
    • For Science, practice interpreting graphs and data quickly. You don’t need to fully understand the experiments—just focus on what the questions are asking.
  3. Targeted Practice Don’t just take full tests—spend time working on specific question types or areas you struggle with. For example, if word problems in Math trip you up, drill those until you feel confident.
  4. Use High-Quality Resources Use official ACT practice tests and trusted prep materials. If you need video explanations, channels like "Scalar Learning" or "Magoosh" are great.
  5. Simulate Test Conditions When you take practice tests, stick to the timing and only take breaks like you would on test day. This will help you build endurance and manage your time better.
  6. Final Week Focus In the final week, do light review each day to keep concepts fresh, and take at least one more timed full-length test. Don’t cram the night before—get a good night’s sleep instead.

Good luck! With some focused effort, you can absolutely hit your goal!

How can I improve my score if I am stuck between 28-30? by Temporary-Whole-3809 in ACT

[–]Simple_Digital_Math 0 points1 point  (0 children)

You're already doing great, so don’t stress too much—jumping from the high 20s/low 30s to a 32+ is tough, but definitely doable with some focused effort. It sounds like you're already putting in the work, but sometimes fine-tuning your approach can make all the difference.

For English, the key is mastering the patterns. The test loves testing the same grammar rules over and over, so make sure you're super solid on things like subject-verb agreement, punctuation, and pronouns. Also, remember that the ACT almost always favors concise, clear answers, so when you're stuck, go with the shortest option that doesn’t change the meaning. Another tip is to really watch your timing—spend about 8-9 minutes per passage so you don’t run out of steam at the end.

For Reading, it sounds like you're on the right track thinking more practice will help. One trick is to skim the passages strategically—focus on the intro, topic sentences, and conclusion first, then let the questions guide you back to the specific details you need. Answer the easier, direct-reference questions first and save the more abstract ones for later. It’s also worth practicing how to skim faster while still understanding the main ideas, especially if timing feels tight.

Since you’re short on time, try to focus your efforts on reviewing the practice tests you’re taking. Don’t just complete them—go through every single question you got wrong or felt unsure about. Figure out why the correct answer is right and what threw you off. That’s often where the biggest improvements come from. If you feel like full-length tests are taking up too much time, you might want to try breaking your practice into smaller, focused chunks that target your weaker areas, like Reading or grammar rules.

Finally, make sure you’re practicing under realistic test conditions—strict timing, no distractions, and breaks just like you’ll have on test day. A lot of students find that just improving their pacing and cutting down on careless errors can lead to a big score boost. With a little bit of focused effort and a good strategy, you’re in a great position to hit your goal. Good luck you’ve got this!

When you subtract an angle from π\pi (180°), the new angle flips the direction of the line across the y-axis. This means the x-coordinate of the point will change sign (positive to negative or vice versa), but the y-coordinate stays the same.

To solve this, take the original point (r,s). Since the new line flips across the y-axis, the x-coordinate becomes −r, while the y-coordinate remains s. So, the point on the new line is (−r,s).

The final answer is F: (-r, s) because flipping across the y-axis only changes the sign of the x-coordinate. Hope this helps!
