Answer:
Step-by-step explanation:
Begin by isolating x. To do this, you can substract 24 on both sides.
That's your answer. Any value of ''x'' must be greater than 28 for this inequality to be true.
Answer:
a) the trigonometric function is;
b) ( to two decimal places)
Step-by-step explanation:
This data can be represented by the sinusoidal function of the form :
where A = amplitude and which can be determined via the formula:
A = 7.5° C
where B = the frequency;
Since the data covers a period of 3 days ; then
( where 365 is the time period )
The vertical shift is found by the equation D;
D =
D =
D = 21.5
Replacing the values of A ; B and D into the above sinusoidal function; we have :
From the question; when it is 7th of the year ( i.e January 7);
t = 7 and the temperature (y) = 29° C
replacing that too into the above equation; we have:
Thus; the trigonometric function is;
Similarly; to determine the temperature o Jan 31; i.e when t= 31 ; we have :
( to two decimal places)
The Correct choice is : C
As we can observe, the y - coordinate ( ordinate ) of the given point (2 , 0) is 0. so it's obvious that it's distance from x - axis is Zero. In other words we can say that the point is lying on x - axis.
