Answer:

Step-by-step explanation:

the sum of the exterior angles of a polygon = 360°

sum the 4 exterior angles and equate to 360

8x + 9x + 5 + 5x + 4 + 9x + 3 = 360 , that is

31x + 12 = 360 ( subtract 12 from both sides )

31x = 148 ( divide both sides by 31 )

x ≈ 11.23 ( to 2 dec. places )

then exterior angle at B is

9x + 3 = 9(11.23) + 3 ≈ 104° → C

Don’t know much about geometry

Mariana [72]

Answer:

Step-by-step explanation:

J is a tangent to the circle and it is at right angle,

So applying Pythagorean theorem

HK² = KJ² + HJ²

HK² = 8²+ 15²

HK² = 64 + 225

HK² = 289

HK = √289

HK = 17 mi

Michelle kicks a soccer ball up into the air from the ground. The graph represents the height of the ball, in feet, as a functio

marusya05 [52]

Answer: domain: 0 ≤ x ≤ 8

Step-by-step explanation:

Domain is an independent variable with a minimum and a maximum value. Or the starting point (value) to the end point (value)

The time taken by the ball is from 0 to 8 seconds

The domain of the function represented by the graph will be from the starting time of the ball to the end time. Therefore, In this case, domain will be

0 ≤ x ≤ 8

Answer:

f(x) should be reflected across the y-axis
f(x) should be horizontally translated

Step-by-step explanation:

We imagine Jenessa's elevation plots might look like those in the attachment. The red graph would be of f(x) when preparing for the race, and the green graph would be f(x) during the race.

The green graph is not a simple reflection or translation of the red graph, but is a combination of both. Thus, the two answer choices shown above are both applicable.

How do you do this? I'll give brainliest, please help.

Dmitriy789 [7]

Answer:

Domain is all values of X or (-∞,∞)

Range is all the possible values of Y. Since it goes up to 3, and then it goes down, it's all values less than or equal to y, or (-∞,3] or y ≤ 3 (depending on how you need to enter the response.

Why are there 27 cubic feet in one cubic yard

kobusy [5.1K]

One cubic yard is equal to 27 cubic feet because one yard is equal to 3 feet

Solution:

Given that, there 27 cubic feet in one cubic yard

Yard and feet are units of distance

1 Yard (yd) is equal to 3 feet (ft). To convert yards to feet, multiply the yard value by 3.

The conversion factor for 1 yard to 1 feet is given as:

$1 \text{ yard } = 3 \text{ foot }$

Now find for 1 cubic yard . Cubic yard means yard raised to power 3

Therefore,

$1\ yard^3 = (3)^3\ feet^3\\\\1\ yard^3 = 27 feet^3\\\\1\ cubic\ yard = 27\ cubic\ feet$

Thus one cubic yard is equal to 27 cubic feet

Therefore, there are 27 cubic feet in one cubic feet
