Answer:
The correct option is C). When it was purchased, the coin was worth $6
Step-by-step explanation:
Given function is f(t)=
Where t is number of years and f(t) is function showing the value of a rare coin.
A figure of f(t) shows that the graph has time t on the x-axis and f(t) on the y-axis.
Also y-intercept at (0,6)
hence, when time t was zero, the value of a rare coin is 6$
f(t)=
f(0)=
<em>f(0)=6</em>
Thus,
The correct option is C). When it was purchased, the coin was worth $6
X+1 is the answer for this question
Answer: see graph
<u>Step-by-step explanation:</u>
Look at the Unit Circle to see the coordinates of the quadrangles.
Build a sine table for one period (0° - 360°).
<u> x </u> <u> y = sin(x) </u> <u> y² = (sin(x))² </u> <u> (x, y²) </u>
0° sin(0°) = 0 (0)² = 0 (0°, 0)
90° sin(90°) = 1 (1)² = 1 (90°, 1)
180° sin(180°) = 0 (0)² = 0 (180°, 0)
270° sin(270°) = -1 (-1)² = 1 (270°, 1)
360° sin(360°) = 0 (0)² = 0 (360°, 0)
Now plot the (x, y²) coordinates on your graph.
ANSWER
The solution set is (4,6)
EXPLANATION
The first equation is
The intercepts are:
(0,18) and (6,0).
We plot the intercepts and draw a straight line through them.
The second equation is,
This equation also passes through,
(0,0) and (1,1.5).
We plot this point too and draw a straight line through them.
The two straight lines intersect at (4,6).
See graph.
Hence the solution set is (4,6).
