Answer:
In this question there is a change of two things
- time
- temperature
(88 + 92 + 96 + x) / 4 = 90
(276 + x) / 4 = 90
276 + x = 90 * 4
276 + x = 360
x = 360 - 276
x = 84 <=== he would need an 84
Answer: The only difference between the six functions depends on the sides we use.
Step-by-step explanation:
The primary trigonometry ratio are
Sine (sin)
Cosine (cos)
Tangent (tan)
The reciprocal ratio are derived from the three primary functions. Because they can easily be derived, calculators and spreadsheets do not usually have them. These are:
Secant (sec)
Cosecant (csc)
Cotangent (cot)

Answer:
At either b = -12 or b = +14, the equation has a unique solution.
Step-by-step explanation:
The quadratic equation w^2 + bw + 36 = 0 has three coefficients: a = 1, b and c = 36. This equation will have a unique solution (which is also real, not complex) if the discriminant b^2 - 4ac is zero. Here b^2 - 4ac can be rewritten as
b^2 - 4(1)(36). Setting this equal to zero, we get
b^2 - 144 = 0, which is equivalent to b^2 = 144. Thus, b = ± 12.
At either b = -12 or b = +14, the equation has a unique solution.
