Answer:
y = 5 sin (2x) + 4
Step-by-step explanation:
this is sines function,
the amplitude is [9 - (-1)]/2 = 10/2 = 5
the period is 2πx/π = 2x
the x-axis of actual function is at y = 4
so, the function is :
y = 5 sin (2x) + 4
ANSWER
(-2,4] and [7,∞).
EXPLANATION
The domain refers to the interval on which the function is defined.
In the case of the graph, the domain refers to all the x-values for which the graph exists.
The graph is defined for x-values greater than 2 but less than or equal to 4 and
x-values greater than or equal to 7.
In interval notation, we have:
(-2,4] and [7,∞).
The second choice is correct:
“Finally, tortoises make excellent pets. They are clean and quiet animals that help control insects. Tortoises live for a long time and can become part of the family.“ would be the strongest conclusion.
(3/5 + -1/4)/(7/10)
get a common denominator of 20
3/5 * 4/4 =12/20
-1/4 * 5/5 = -5/20
7/10 *2/2 = 17/20
replace
(12/20 - 5/20)/(14/20)
add the top
(7/20)/(14/20)
copy dot flip
7/20 * 20/14
7/14
1/2
