1. You are standing on top of a ridge using a clinometer trying to figure out how far your dog has wandered off in

olga_2 [115]

<u>Given:</u>

It is given that the ridge is 360 inches tall.

<u>Assumptions:</u>

Assume you are 170.1 cm tall which equals 67 inches tall, the height from your eye to the floor is $360+67 = 427$ inches.

The distance from your eye level to the bottom of the ridge is 427 inches.

Assume the angle A is 60°.

<u>To find the distance from you to your dog.</u>

<u>Solution:</u>

A right-angled triangle can be formed where the angle is 60°, the distance between you and the dog is the hypotenuse of the triangle and your height from the floor is the adjacent side of the triangle.

Assume the hypotenuse of the triangle measures x inches.

To determine the length of the hypotenuse, we determine the cos of the angle.

$cos \theta = \frac{adjacent side}{hypotenuse} .$

$cos A = \frac{427}{x} , x = \frac{427}{cos60} , cos60=0.5.$

$x=\frac{427}{0.5} = 854.$

So if the ridge is 360 inches tall and you are 67 inches tall and the angle A is 60°, the distance between your dog and you is 854 inches.

What is they-intercept for the<br> equation 8x + 3y = -24?

FromTheMoon [43]

Answer:

y=-8

Step-by-step explanation:

First, rewrite the equation in slope-intercept form:

$y=-\frac{8}{3}x-8$

Now just look at the slope-intercept form and your y-intercept is -8, and your slope is $-\frac{8}{3} x$ .

If you don't know what slope-intercept form is it is y=mx+b where m is your slope and b is your y-intercept.

Hope this helps! :)

Which equals cos A to the nearest hundredth?

rusak2 [61]

Answer:

cosA ≈ 0.55

Step-by-step explanation:

cosA = $\frac{adjacent}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{6}{11}$ ≈ 0.55 ( to the nearest hundredth )

4, 12, 16, 48, 64, 192,

Brut [27]

Answer:

The next term in the series is 256

Step-by-step explanation:

Lets explain how to solve the problem

The series is:

4 , 12 , 16 , 48 , 64 , 192

If we subtract 12 - 4 = 8

If we subtract 16 - 12 = 4

The difference is not constant then it's <em>not an arithmetic series</em>

If we divide 12 by 4 the answer is 3

If we divide 16 by 12 the answer is 4/3

The ratio is not constant then it's <em>not a geometric series</em>

So lets look to the odd positions 1st , 3rd , 5th, they are:

4 , 16 , 64

16 ÷ 4 = 4

64 ÷ 16 = 4

<em>There is a constant ratio 4 between each 2 consecutive odd position</em>

<em>terms</em>

Lets look to the even positions 2nd , 4th , 6th, they are:

12 , 48 , 192

48 ÷ 12 = 4

192 ÷ 48 = 4

<em>There is a constant ratio 4 between each 2 consecutive even position</em>

<em>terms</em>

Now we can find any term is the series by <em>multiply the previous odd</em>

<em>position by 4 if the term in odd position</em> and <em>multiply the previous</em>

<em>even position by 4 if the term in even position</em>

The next term is in the 7th position, then the next term is:

The number in the 5th position × 4

∵ The number in the 5th position is 64

∴ The number in the 7th position = 64 × 4 = 256

* The next term in the series is 256
