Answer:

30m + 75

$255

Step-by-step explanation:

Since John  has to pay a monthly fee of 0, you can let m represent the number of months and then add the one time membership fee of $75.

30 multiplied by 6 is 180 and 180 plus 75 is 255.

Use a double angle or half angle identity to find the exact value of each expression
STatiana [176]

Answer:

Step-by-step explanation:

There are 2 very distinct and important things that we need to know before completing the problem. First is that we are given that the cos of an angle is 1/3 (adjacent/hypotenuse) and it is in the first quadrant. We also need to know that the identity for sin2θ = 2sinθcosθ.

We already know cos θ = 1/3, so we need now find the sin θ. The sin ratio is the side opposite the angle over the hypotenuse, and the side we are missing is the side opposite the angle (we do not need to know the angle; it's irrelevant). Set up a right triangle in the first quadrant and label the base with a 1 (because the base is the side adjacent to the angle), and the hypotenuse with a 3. Find the third side using Pythagorean's Theorem:

3^2=1^2+y^2 which simplifies to

9=1+y^2 and

y^2=8 so

y=\sqrt{8}=2\sqrt{2} so that's the missing side. Now we can easily determine that

sin\theta=\frac{2\sqrt{2} }{3}

Now we have everything we need to fill in the identity for sin2θ:

2sin\theta cos\theta=2(\frac{2\sqrt{2} }{3})(\frac{1}{3}) and multiply all of that together to get

2sin\theta cos\theta=\frac{4\sqrt{2} }{9}

An electrical pole is 12.4m tall. It is supported by a guy wire that is 17.3 long. how far is the anchor of the guy wire to the
kari74 [83]

The anchor of the guy wire is 12.06 meters away form base of electrical pole.

Further explanation:

The whole given scenario forms a right angle triangle. The pole is standing straight so it is the perpendicular while the guy wire goes from the top of pole to the anchor so it will be the hypotenuse. We have to finds the base.

Pythagoras theorem will be used.

Pythagoras theorem states that:

H^2=B^2+P^2

Given

Base=?

Perpendicular=12.4 m

Hypotenuse = 17.3 m

Putting the values

(17.3)^2=B^2+(12.4)^2\\299.29=B^2+153.76\\B^2=299.29-153.76\\B^2=145.53\\Takeing\ Square\ root\ on \both\ sides\\\sqrt{B^2}=\sqrt{145.53}\\B=12.06\ m

The anchor of the guy wire is 12.06 meters away form base of electrical pole.
