List and describe four ways in which colleges use ACT scores.
if its correct u get brainly
Answers
Colleges use ACT scores as a key factor in the admission process, scholarship, placement and eligibility
Describing the ways to use ACT scores
Admission: Colleges use ACT scores as a key factor in the admission process. Many colleges have a minimum ACT score requirement for admission, and students who score below the minimum may not be accepted. The score also helps admissions officers evaluate applicants and determine their academic preparedness for college.
Scholarship awards: Many colleges offer scholarships based on ACT scores. Students who score high on the ACT may be eligible for more scholarship money, which can help offset the cost of tuition.
Placement: Colleges use ACT scores to place students in appropriate courses. Students who score well on the ACT may be able to bypass introductory courses and enroll in higher-level courses, while students who score lower may need to take remedial courses to build foundational knowledge.
Program eligibility: Some programs at colleges have specific ACT score requirements for admission. For example, students who want to enter a pre-med or engineering program may need a minimum ACT score to be considered for admission. The score also helps determine eligibility for honors programs or other specialized programs within the college.

Answers
Answer:
1
Explanation:
The expression that is equivalent to [(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹ is;
1/(36a⁴b¹⁰)
The given expression is;[(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹
Rewriting this equation gives;[(2a⁻³b⁴)² × (3a⁵b)²]⁻¹
Let us simplify (2a⁻³b⁴)² to get;
4b⁸/a⁶
Similarly for (3a⁵b)²;
⇒ 9a¹⁰b²
Thus, we now have;
[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹
From laws of indices, we know that; x⁵/x³ = x⁽⁵ ⁻ ³⁾ = x²Thus; a¹⁰/a⁶ = a⁴
Similarly b⁸ × b² = b⁽⁸ ⁺ ²⁾ = b¹⁰
Thus, we now have;[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹ = (36a⁴b¹⁰)⁻¹
Finally, we now have;
(36a⁴b¹⁰)⁻¹ = 1/(36a⁴b¹⁰)

Evaluate the line integral, where c is the given curve. (x + 8y) dx + x2 dy, c c consists of line segments from (0, 0) to (8, 1) and from (8, 1) to (9, 0).
Answers
Parameterize the path from (0, 0) to (8, 1) by
• x(t) = 8t and y(t) = t
and the path from (8, 1) to (9, 0) by
• x(t) = 8 + t and y(t) = 1 - t
both with 0 ≤ t ≤ 1.
Over the first path, we have
[tex]\displaystyle \int_{C_1} (x+8y) \, dx + x^2 \, dy = \int_0^1 (8t + 8\cdot t) \cdot (8 \, dt) + (8t)^2 \cdot dt = \int_0^1 (128t + 64t^2) \, dt = \frac{256}3[/tex]
and over the second path,
[tex]\displaystyle \int_{C_2} (x+8y) \, dx + x^2 \, dy = \int_0^1 ((8 + t) + 8(1-t)) \cdot dt + (8+t)^2 \cdot (-dt) \\\\ = \int_0^1 (-48 - 23t - t^2) \, dt = -\frac{359}6[/tex]
and so the total line integral is
[tex]\displaystyle \int_C (x+8y) \, dx + x^2 \, dy = \frac{256}3 - \frac{359}6 = \boxed{\frac{51}2}[/tex]
