The value of cos theta is 2/√29

<h3>Trigonometry identity</h3>

A trigonometry identity are expressions expressed as cosine, tangent, sine.

Given the following trigonometry identity

cot theta = 2/5

1/tan theta = 2/5

tan theta = 5/2

Determine the hypotenuse

hyp² =5^2 + 2^2

hyp² = 25 + 4

hyp = √29

Determine the value of cos theta

cos theta= adj/hyp

cos theta= 2/√29

Hence the value of cos theta is 2/√29

Answer:

Step-by-step explanation:

Corresponding angles form a sideways U when you connect the angles.

b is the only one that does that.

1 and 4 are consecutive angles.

1 and 3 are vertical angles

4 and 3 are linear pair angles.

Find all points on the curve that have the given slope.x = 2cost, y= 8sint, slope =-1

tatuchka [14]

Answer:

$t_{1} = 0.422\pi \pm \pi\cdot i$ , $\forall \,i \in \mathbb{N}_{O}$

$t_{2} = 1.422\pi \pm \pi\cdot i$ , $\forall \,i \in \mathbb{N}_{O}$

Step-by-step explanation:

In the case of parametric equations, the slope of the curve is equal to:

$\frac{dy}{dx} = \frac{\frac{dy}{dt} }{\frac{dx}{dt} }$

Where $\frac{dx}{dt}$ and $\frac{dy}{dt}$ are the first derivatives of $x$ and $y$ regarding $t$ . Let be $x(t) =2\cdot \cos t$ and $y(t) = 8\cdot \sin t$ , their first derivatives are found:

$\frac{dx}{dt} = -2\cdot \sin t$ and $\frac{dy}{dt} = 8\cdot \cos t$

Thus, equation for the slope is:

$\frac{dy}{dx} = -\frac{8\cdot \cos t}{2\cdot \sin t}$

$\frac{dy}{dx} = -\frac{4}{\tan t}$

If $\frac{dy}{dx} = -1$ , then:

$-1 = -\frac{4}{\tan t}$

$\tan t = 4$

Tangent is positive at 1st quadrant and is a function with a periodicity of $\pi$ , the set of solutions are:

$t_{1} = 0.422\pi \pm \pi\cdot i$ , $\forall \,i \in \mathbb{N}_{O}$

$t_{2} = 1.422\pi \pm \pi\cdot i$ , $\forall \,i \in \mathbb{N}_{O}$

A bag with 8 marbles are shown below.What is the probability that they are white or grey

horrorfan [7]

Answer: 2/8

Step-by-step explanation:

The probability that the marbles are white or grey is 2/8 because since there is 2 marbles and the total is 8 so you have a probability of 25% to get white or gray
