Answer:

Step-by-step explanation:

Suppose the radius is 1. The parametric equations for the circle are

x = cosθ

y = sinθ

x:y = 3:1

tanθ = ⅓

cosθ = 3/√(1²+3²) =  3/√10

sinθ = 1/√10

The solutions are (3/√10, 1/√10) and (-3/√10, -1/√10).

Tell whether the angles are adjacent or vertical. Then find the value of x.
krok68 [10]

Answer : The angles are vertical angles and the value of x is 25^o

Step-by-step explanation :

Adjacent angles : It is defined as the two angles that have the common arm and common vertex.

Vertical angles : It is defined as the two lines intersect each other and form angles. The opposite angles are known as vertically opposite angles.

And we know that the vertically opposite angles are equal.

In the given image, the angles are vertical angles and vertically opposite angles are equal.

So,

(4x-25)^o=75^o

4x-25^o=75^o

4x=75^o+25^o

4x=100^o

x=\frac{100^o}{4}

x=25^o

Therefore, the angles are vertical angles and the value of x is 25^o

INCREDIBLY URGENT!

Answer:

a) By graphing just one interval of length T. b) Infinite number of angles, c) Infinite times.

Step-by-step explanation:

Any function is periodical when:

f(t) = f(t+i\cdot T), \forall i \in \mathbb{N}_{O}

Where T is the period of the function. The periodicity of the function allows us to limit the graphing of the function to just an interval of one period and according to the definition, you can expect same output with n different angles (infinite number of angles and same output infinite times).

BENJamin is putting a fence around his rectangular shaped yard.the yard is 35 feet long and 22 feet wide. The cost of the fence
SSSSS [86.1K]
Perimeter: 2l+2w=P
Plug in: 2(35)+3(22)=P
Solve: 70+66=136
The total perimeter of his yard is 136 feet.
Half times $7.25: 136/2=68(7.25)=493
The total cost for half his yard is $493 :)
