Answer:

Step-by-step explanation:

y - 3 = 1/4(x - 4)

now use algebra to get the above point-slope formula in the slope-intercept formula

y - 3 = 1/4(x - 4)

y - 3 = 1/4x -1

y = 1/4x +2

now that you have the slope-intercept form graph it

So firstly, we have to find the radius of the circular garden before finding the circumference (the amount of fencing needed to surround the garden). To find the radius, use the area formula ( $A=\pi r^2$ ), plug in the area of the garden (36 ft^2) and solve for r as such:

$36=\pi r^2\\ \frac{36}{\pi}=r^2\\ \frac{\sqrt{36}}{\sqrt{\pi}}=r\\ \frac{6}{\sqrt{\pi}}=r$

So that we know the radius, plug that into the circumference equation ( $C=2\pi r$ ) to solve:

$C=2\pi*\frac{6}{\sqrt{\pi}}\\ C=\frac{12\pi}{\sqrt{\pi}}\\ C=12\sqrt{\pi}$

Your answer is A. 12√π.

A person on a runway sees a plane approaching. The angle of elevation from the runway to the plane is 11.1° . The altitude of th

Gnoma [55]

Answer:

The horizontal distance from the plane to the person on the runway is 20408.16 ft.

Step-by-step explanation:

Consider the figure below,

Where AB represent altitude of the plane is 4000 ft above the ground , C represents the runner. The angle of elevation from the runway to the plane is 11.1°

BC is the horizontal distance from the plane to the person on the runway.

We have to find distance BC,

Using trigonometric ratio,

$\tan\theta=\frac{Perpendicular}{base}$

Here, $\theta=11.1^{\circ}$ ,Perpendicular AB = 4000

$\tan\theta=\frac{AB}{BC}$

$\tan 11.1^{\circ} =\frac{4000}{BC}$

Solving for BC, we get,

$BC=\frac{4000}{\tan 11.1^{\circ} }$

$BC=\frac{4000}{0.196}$ (approx)

$BC=20408.16$ (approx)

Thus, the horizontal distance from the plane to the person on the runway is 20408.16 ft

What is the common difference, d, in the arithmetic sequence defined by the formula below? an=2n+1

marishachu [46]

<h3>Answer:</h3>

d = 2

<h3>Solution:</h3>

We are given that the arithmetic progression is defined by :

➝ 2n + 1

Therefore, 

For first term

➙ n = 1

➝ 2 × 1 + 1

➝ 2 + 1

➝ 3

For second term

➙ n = 2

➝ 2 × 2 + 1

➝ 4 + 1

➝ 5

Common difference

➙ 2nd term - 1st term

➝ 5 - 3

➝ 2

<h3>More information:</h3>

The difference between the successive term and the preceding term is the difference of an arithmetic progression. It is always same for the same arithmetic progression.
