Answer:
x = 7
Step-by-step explanation:
First we find out what we are using sin,cos, or tan then we plug in the numbers
Sin 26 x 16 = 7
A. {–2, –1, 1, 2, 7}
B. {–2, 1, 3, 4, 5, 7}
C. {1, 2, 7}
D. {1, 3, 4, 5}
Answer: he had $61
Step-by-step explanation: 52+9=61
How do I solve this equation
Answer:
or
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s ----> the speed
x ----> the distance
y ----> the time
so
we have
Remember that
so
Find out the speed in miles per hout
Simplify
or
The function f(t) = t2 + 4t − 14 represents a parabola.
Part A: Rewrite the function in vertex form by completing the square. Show your work. (6 points)
Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points)
Part C: Determine the axis of symmetry for f(t). (2 points)
y + 14 + 4 = ( t2 + 4t +4)
y + 18 = ( t + 2)^2
so the vertex of the parabola is ( -2 , -18)
the axis of symmetry is y = -18
