Answer: The x-intercepts represents the points at which the parabola crosses the axis of x.
Step-by-step explanation:
If it exist then the x-intercepts represent the zeros, roots, or quadratic function, the values of x at y = 0. Then the parabola does not cross the x-axis, so it has no zeros.
C. It is always a rational number. You cannot determine its sign without knowing the values of a and b.
The answer is 7/25, because cos is opposite/hypothenuse.
Answer:
23)
P = 20x^2 + 14xy^2
A = 70x^3y^2
24)
P = 8a^3b + 4ab
A = 4a^4b^2
25)
A = 18x^3y
Step-by-step explanation:
23)
P = 2(10x^2 + 7xy^2)
P = 20x^2 + 14xy^2
A = 10x^2 x 7xy^2
A = 70x^3y^2
24)
P = 2a^3b + 6a^3b + 4ab
P = 8a^3b + 4ab
A = 1/2(2a^3b)(4ab)
A = 4 a^4 b^2
25)
A = 1/2(4xy+8xy)(3x^2)
A = 1/2(12xy)(3x^2)
A = 18x^3y
