Speed, Time, and Dis

Mathematics
1 answer:
serious [3.7K]4 years ago
7 0

Answer:

3 hours

Step-by-step explanation:

Recall:

Distance = speed x time

we are given that speed = 18 km/h and distance = 54 km.

hence,

54 = 18 x time   (divide both sides by 18 and rearrange)

time = 54/18 = 3 hours

What basic trigonometric identity would you use to verify that sin x +1/ sin x=1 +csc x
SVETLANKA909090 [29]

Answer:  The correct option is (c). \csc x=\dfrac{1}{\sin x}.

Step-by-step explanation:  We are given to select the correct basic identity that we will use to verify the following:

\dfrac{\sin x+1}{\sin x}=1+\csc x.

We have

\dfrac{1+\sin x}{\sin x}\\\\\\=\dfrac{1}{\sin x}+\dfrac{\sin x}{\sin x}\\\\\\=1+\dfrac{1}{\sin x}.

In order to verify the given trigonometric equation, we must have

1+\dfrac{1}{\sin x}=1+\csc x\\\\\\\Rightarrow \dfrac{1}{\sin x}=\csc x\\\\\\\Rightarrow \csc x=\dfrac{1}{\sin x}.

Thus, the required identity that we will use is

\csc x=\dfrac{1}{\sin x}.

Option (c) is CORRECT.

Please help Solve X^2= -36
denis-greek [22]

Answer:

x = ±6i

Step-by-step explanation:

x^2 = -36

Take the square root of each side

sqrt(x^2) = ±sqrt(-36)

We know that sqrt(ab) = sqrt(a)sqrt(b)

x = ±sqrt(-1) sqrt(36)

We know that sqrt(-1) = i

x = ±i 6

x = ±6i
