Trigonometric identities assignment 4

Answer:

<em>Answer: choice D.</em>

Step-by-step explanation:

<u>Trigonometric Functions</u>

We need to recall some properties and definitions of the trigonometric functions.

$\displaystyle \tan \theta=\frac{\sin\theta}{\cos\theta}$

$\displaystyle \sec \theta=\frac{1}{\cos\theta}$

We need to simplify the following expression:

$5\sin\theta\sec\theta$

Substituting the identity for the secant:

$\displaystyle 5\sin\theta\sec\theta=5\sin\theta.\frac{1}{\cos\theta}$

Operating:

$\displaystyle 5\sin\theta\sec\theta=5\frac{\sin\theta}{\cos\theta}$

Substituting the definition of the tangent:

$\displaystyle 5\sin\theta\sec\theta=5\tan\theta$

Correct choice D.

If John is driving 70 mi/hr and Jim is driving 50 ft/min, who is driving faster?

lapo4ka [179]

Answer:

John

Step-by-step explanation:

70 mi/(60 min) ≈ 1 1/6 mi/min.

1 1/6 miles is significantly farther than 50 ft, so John is driving (much) faster.

How do you do this problem?

astra-53 [7]

By substitution is how to solve

2x-3y=21
y=3-x

2x-3(3-x)=21
2x-9+3x=21
5x=30
x= 6

now substitute our x value into y=3-x
so we get

y=3-6 = -3

so x=6 and y=-3 hope this helps!!!!! Thank you!
