Answer:
The answer is below
Step-by-step explanation:
The function B can be represented by the function:
B = C + Acos(Pt)
a) From the graph of the function, it starts from 30, hence it is a cosine function.
The amplitude (A) = (highest value - lowest value) / 2 = (30 - 10) / 2 = 10
A = 10
b) The function completes an oscillation every 12 months, hence its period (P) = 12
c) The average value = 10/√2
d) The vertical shift (C) is the difference between the highest and lowest value.
Therefore, C = 30 - 10
C = 20
Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180
Answer:
Step-by-step explanation:
sustiute 1 and -1 to x y=tan^3(x) you get postive and negative values , odd function
y=1/sec^3 x is even and same goes on
Answer:
since the rate at which concentration inside the cell is proportional to the difference in the concentration of the solute in the blood stream and the concentration within the cell, then the rate of change of concentration within the cell is equals to K(L-C).
Thus, the required differential equation is Δc/Δt = K( L - C ).
Step-by-step explanation:
Answer: 67°.
Step-by-step explanation:
1) m∠PMR=m∠LMN=3x+19°;
2) m∠LMN+m∠LMP=180°, it can be written as 3x+19+9x-31=180;
3) if to solve the equation 3x+19+9x-31=180, then x=16;
4) m∠PMR=3x+19=48+19=67°.
