joshua is hiking glacier national park he has now hiked a total of 17km and is 2km short of being 1/2 of the way done with his h

elixir [45]

If he hikes another 2 km, he will be halfway there.

17+2= (1/2)x
19=(1/2)x
38=x

Final answer: The total length of the hike is 38 km

Can someone answer this its just boxplots :)))

Vitek1552 [10]

<h3>Answer: 50%</h3>

Explanation:

The boxplot, aka box-and-whisker plot, is a visual way to represent summary data. Each piece of the boxplot visually tells us one of the five items of a five number summary, which are:

Min = smallest value
Q1 = first quartile
Median = middle most value
Q3 = third quartile
Max = largest value

The median is the vertical line inside the box of the boxplot. The diagram shows that the median is 25. Exactly half of the distribution is below the median, and the other half is above the median. So that means that 50% of the cars get at least 25 mpg.

Mountain officials want to know the length of a new ski lift from A to C , as shown in the figure below. They measure angle DAC

Ede4ka [16]

We assume that the hill is represented by points ACD and the ski lift is represented by points BCD. From the description above, points CDB would have an angle of 90 degrees. Then, we would have:

sin (32) = CD / 960
CD = 508.72

tan 32 = 508.72 / AD
AD = 814.13

Therefore, the distance would be 814.13 - 508.72 = 305.4 ft.

Determine and state the vertex of f(x) = x2 - 2x - 8 using the method of completing the square

Elza [17]

Answer:

vertex = (1, - 9 )

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = x² - 2x - 8
