8x^4 + 2x^2 - 45 = (2x^2 + 5)(4x^2 - 9) = (2x^2 + 5)(2x + 3)(2x - 3)
(a) 2x^2 + 3....no
(b) 2x^2 + 5...yes
(c) 2x - 3....yes
(d) 4x^2 - 9)...no...not when it is fully factored
Answer:
112.6°
Step-by-step explanation:
Using cosine law:
20² = 11² + 13² - 2(11)(13)cos(A)
110 = -286cos(A)
cos(A) = -5/13
A = 112.6198649
Answer:
i believe its 24 if i got it wrong sorry :c
Step-by-step explanation:
Answer:
The line which has slope 1/3 is a shallow line.
The line which has slope 2 is a steep line.
Both are increasing.
Step-by-step explanation:
Compare the lines by finding the slope between each pair of points.
Using the slope formula, substitute the points.


The line which has slope 1/3 is a shallow line.
The line which has slope 2 is a steep line.
