Answer:

12%

Step-by-step explanation:

well when you get 72/6 and to make it into a easier full number/ (not a fraction) you get 12 then you put the % behind it and now you have 12%

The length and width of a rectangular frame is 15 inches and 8 inches.What is the length of the diagonal of this frame

anastassius [24]

Answer:

The length of the diagonal of the frame equal 17 inches

Step-by-step explanation:

The diagonal dividing the rectangle as made the rectangle 2 triangles

So according to Pythagoras Theorem,

Hypothenus² = opposite² + adjacent²

The diagonal lent is the Hypothenus.

so the two other sides are taking as opposite and adjacent respectively

so taking h as hypothenus,

h² = 15² + 8²

h² = 225 + 64

h² = 289

h = √289

h = 17

The difference between the rate of change of B and the rate of change of A is 15.

<h3>How to get the difference in the rates of change?</h3>

First, we need to get the two rates of change.

We have two linear functions.

A: y = 35*x

For function A the rate of change is the slope, wich is 35.

Function B is graphed.

Remember that if a line passes through two points (x₁, y₁) and (x₂,y₂) then the slope is:

$a = \frac{y_2 - y_1}{x_2 - x_1}$

In the graph, we can see that line B passes through (0, 0) and (1, 50), then the slope is:

$a = \frac{50 - 0}{1 - 0} = 50$

Then the rate of change of B is 50.

The difference between the rates of change is:

diff = 50 - 35 = 15

Answer:

$\tan \theta = - \frac{1}{5} = - 0.2$

$\cos \theta = 0.98$

$\sin \theta = - 0.196$

Step-by-step explanation:

It is given that $\cot \theta = - 5$ and $\theta$ is in the fourth quadrant.

So, only $\cos \theta$ will have positive value and $\sin \theta$ , $\tan \theta$ will have negative value.

Now, $\cot \theta = - 5$

⇒ $\tan \theta = \frac{1}{\cot \theta} = -\frac{1}{5}$ (Answer)

We know, that $\sec^{2} \theta - \tan^{2} \theta = 1$

⇒ $\sec \theta = \sqrt{1 + \tan^{2} \theta } = \sqrt{1 + (- \frac{1}{5} )^{2} } = 1.019$

{Since, $\cos \theta$ is positive then $\sec \theta$ will also be positive}

⇒ $\cos \theta = \frac{1}{\sec \theta} = \frac{1}{1.0198} = 0.98$ (Answer)

We know, that $\csc^{2} \theta - \cot^{2} \theta = 1$

⇒ $\csc \theta = - \sqrt{1 + \cot^{2} \theta } = - \sqrt{1 + (- 5 )^{2} } = - 5.099$

{Since, $\sin \theta$ is negative then $\csc \theta$ will also be negative}

⇒ $\sin \theta = \frac{1}{\csc \theta} = \frac{1}{- 5.099} = - 0.196$ (Answer)
