Answer:
B
Step-by-step explanation:
they are real numbers that are greater than 0 but less than 4
Step-by-step explanation:
Step 1: From the given equation, taking the Left Hand Side (LHS) of the equation
Step 2: Simplify the LHS to make it equal to the Right Hand Side (RHS)
LHS = sin^4x - cos^4x = (sin²x)² - (cos²x)²
= (sin²x - cos²x)(sin²x + cos²x)
= sin²x - (1 - sin²x) since sin²x + cos²x = 1
= 2 sin²x - 1
= RHS
Hence proved.
Answer:
8
Step-by-step explanation:
8*25=2.00
2.00+.90=2.90
The graph of any quadratic equation y=ax2+bx+c y = a x 2 + b x + c , where a, b, and c are real numbers and a≠0 a ≠ 0 , is called a parabola. When graphing parabolas, find the vertex and y-intercept. ... This y-value is a maximum if the parabola opens downward, and it is a minimum if the parabola opens upward.
Vertex: (−1, 3)
Y-intercept: (0, 5)
X-intercepts: None
Extra points: (−3, 11), (−2, 5), (1, 11)
