The months with temperature below 0° is August and October.
GIven,
T(m) = 4 sin (π/6 m)₊2
In the above equation, T(m) is the average temperature in a month in degrees Fahrenheit, and m is the month of the year.
T(8) = 4 sin (8π/6 m)₊2
= 4 sin (4π/3 )₊2
= 4 sin (π₊π/3 )₊2
= ₋4 sin π/3 ₊2
= ₋4×√3/2 ₊2
= ₋2√3 ₊ 2 <0
The function for the average monthly temperature, in m months from january is given by
T(0) = 4 sin(10π/6) ₊ 2
= 4 sin(5π/3) ₊ 2
= 4 sin(2π ₋ π/3) ₊ 2
= - 4sin π/3 ₊ 2 = ₋4 × √3/2 ₊ 2
= ₋2√3 ₊2<0
we can notice that after january, from august till october the months will face temperature below 0 degrees.
So the answer is August and October.

what are the possible numbers of positive, negative, and complex zeros of f(x)=-3x^4+5x^3-x^2+8x+4
Answer:
There could be 0, 2, or 4 complex solutions
Step-by-step explanation:
The Fundamental Theorem of Algebra states that any polynomial with n degree will have n solutions So since the degree of the polynomial you provided has a degree of 4, that means there are 4 possible solutions. This question specifically asks for complex zeroes. Complex zeroes come in conjugate pairs, so that means if you have one complex zero, there is another complex zero which is it's conjugate. For this reason, there can only be an even number of complex zeroes. And since there's 4 possible solutions, There could be 0, 2, or 4 complex solutions

The root rafter of a house has been raised to a height of 18 yards at the ridge. Half of the length of the run measures 14 yards. Find the length of the rafter.
The length of the rafter as detailed in the question is approximately; 22.80 yards
How to use Pythagoras theorem?
The formula for Pythagoras theorem is;
a² + b² = c²
where;
a and b are adjacent and opposite sides of the triangle formed
c is the hypotenuse
Now, a rafter is a sloped member of a roof structure. Thus, if the rafter is raised to a height of 18 yeards, it means that is the vertical height of the top of the rafter to the bottom of the kingpost.
Now, if half the length run is 14 yards, it means that half of the tie beams is 14 yards. Thus, from the base of the rafter to the center of the tie beams is 14 yards. Thus, we will use Pythagoras theorem to find the length of the rafter.
c = √(14² + 18²)
c = √520
c = 22.80 yards

At a weather station in the Artic the temperature was recorded as -23° C.
Two hours later it had fallen by 11° C.
(i) What was the new temperature?
()Four hours after the first readings the temperature was -45° C.
By how much had the temperature fallen in four hours.
Answer:
(i) -34° C.
(ii) The temperature had fallen by 11° C.
Step-by-step explanation:
(i) As it's a negative number its like we are adding it so 23 + 11 = 34 and as it is a negative number it would be -23 - 11 = -34 which makes it -34° C.
(ii) We know that the temperature now is -45° C, we need to find out how much the temperature had fallen in the 4 hours which had passed. So what we do is essentially add it considering its a negative number so we add -34 by 11 which equals -45. We do this so we can find out how much the temperature had dropped within the 4 hours and as we know that we needed to add 11 to the previous temperature (-34° C) it means that the temperature has dropped by 11° C.

Suppose that a probability is approximated to be zero based on empirical results. Does this mean that the event is impossible?.
Suppose that a probability is approximated to be zero based on empirical results, this does not mean that the event is impossible.
What is probability?The likelihood that an event will occur is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us.
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

According to the data in the figure, find the value of x and y.
Answer:
This is a educated guess, but x is 80 and y is 100.
Step-by-step explanation:
My logic here is that the triangles are the same because of all the congruent lines and stuff. But from there, you know that both the right and the left side are 40 degrees. You know the total degree of a triangle is 180 so 180 - 40 - 40 is 100. So the final angle is 100. If you look at x, its on the outside, but on a line. If you can imagine a circle, its half, so its a 180 degrees total. Then its 180 = x + 100. So x is 80. And then by that same logic its y = 100.
For each of the following a) identify the inverse function needed to solve for the indicated angle and b) solve for the angle (round to the nearest tenth of a degree).
The angle is the cosine inverse function because base over hypotenuse. Then the angle will be 37°.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
