The tangent secant theorem says
PR × PS = PQ²
4 × (4+5) = PQ²
36 = PQ²
PQ=6
Answer: 6
Answer:
D. y = (x - 3)²
Step-by-step explanation:
The parabola formula in vertex form is:
y = a(x - h)² + k
where the vertex is located at (h, k). Replacing with vertex (3, 0) we get:
y = a(x - 3)² + 0
y = a(x - 3)²
In all possible options the leading coefficient <em>a</em> is equal to one. Therefore:
y = (x - 3)²
Answer:
31
Step-by-step explanation:
Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables
Answer:
C and E repr. constant functions.
Step-by-step explanation:
C and E represent constant functions. One can tell immediately by the fact that y remains the same even when x changes.
