Answer:
<em>- 2</em>
Step-by-step explanation:
f(1) = - 2
From the data given, generate first the quadratic equation which best describe the height of the ball. The quadratic function has a general form of
f(x) = Ax^2 + Bx
Substituting the known data,
(1) 148 = A(1^2) + B(1)
(2) 272 = A (2^2) + B (2)
solving for A and B simultaneously,
A = -12
B = 160
To answer this problem, substitute 6 to x. Thus, after 6 seconds, the height is 528 feet.
Answers:
A)
C)
Step-by-step explanation:
<u>Part 1:</u>
We have the followig equation:

We have the followig equation:
Operating with cross product:
Isolating :
Hence, the correct option is C
Answer:
m<PSR = 60°
Step-by-step explanation:
Given:
m<OPQ = 50°
m<ORQ = 70°
Required:
m<PSR
Solution:
m<PQR + m<OPQ + m<ORQ = 180° (Sum of triangle)
m<PQR + 50 + 70 = 180 (Substitution)
m<PQR + 120 = 180
m<PQR = 180 - 120
m<PQR = 60°
One of the properties of a kite states that the angles where the unequal sides meets are congruent to each other. Therefore:
m<PSR = m<PQR
m<PSR = 60° (substitution)
