Given that Ruben's distance from Barstow is d = |210 -60t|, you want to know the time t when he is exactly 90 miles from Barstow.

The absolute value will be 90 when the argument of the function is either -90 or +90.

The question resolves to two equations:

These two-step linear equations can be solved in the usual way:

Then ...

Ruben is 90 miles from Barstow after driving 2 hours, and again after driving 5 hours.

Using translation concepts, the graph of g(x) is given at the end of the answer.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

Function f(x) is a concave up parabola with vertex at (1, -5). For the translation g(x) = f(x + 2), we have that the function is shifted two units left, as:

g(x) = f(x + 2) = (x + 2 - 1)² - 5 = (x + 1)² - 5.

Which is a concave up parabola with vertex at (-1, -5), and the graph is given at the end of the question.

Answer:

2, 5, 6, and 3 or A B C and F

Step-by-step explanation:

The exterior angles are ∠2, ∠3, ∠5 and ∠6.

Angles that are found outside or external to any geometric shape are called exterior angles.

They are also sometimes known as external angles or turning angle.

An exterior angle is made by extending one of the lines of the shape beyond the point of intersection.

Given is a figure, we need to find which of angles in the figure are exterior angles,

So, according to the definition of exterior angles,

The exterior angles are :-

∠2, ∠3, ∠5 and ∠6, because they are outside the figure as well as they are formed by the point of intersections.

Hence, the exterior angles are ∠2, ∠3, ∠5 and ∠6.

Change in Rosa's elevation from starting to end of her hike is 692 feet.

What is elevation in a hike?

Elevation is the height of hiker above the sea level at any point of the hike.

At the starting of the hike , Rosa was at an elevation of = -600feet

At the ending of the hike, Rosa is at an elevation of  = 92 feet

Change in elevation = final elevation - initial elevation

For the line 9x−4y=−36 we have:

x-intercept (-4, 0)

y-intercept (0, 9)

The graph of the line can be seen below.

Here we have the linear equation:

9x - 4y = -36

First, the x-intercept is what we get when y = 0, then:

9x - 4*0 = -36

9x = - 36

x = -36/9 = -4

Then we have the point (-4, 0)

And the y-intercept is what we get when evaluate the variable x = 0, so:

9*0 - 4*y = -36

y = -36/-4 = 9

Then we have the point (0, 9)

Now just graph these two points, and connect them with a line, you will get the graph below.

The time it takes to walk from the first floor to the sixth floor​ is 132.5 seconds.

The division is a process of splitting a specific amount into equal parts.

We have,

To walk from the first floor to the third floor it takes 53 seconds.

From the first floor to the third floor there are two floors.

So we can say that the number of seconds it takes to walk to one floor is 53/2 assuming that each floor has the same height.

We have,

= 53 / 2

= 26.5 seconds

There are 5 floors from the first floor to the sixth floor.

So the time it takes to walk from the first floor to the sixth floor is:

= 26.5 x 5

= 132.5 seconds

We can also say that,

132.5 seconds = 2.20 minutes = 2 minutes 12 seconds

Thus the time it takes to walk from the first floor to the sixth floor​ is132.5 seconds.

First you need to get them into improper fractions. To do that multiply the whole number by the bottom number, and then add the top number:

[tex]-5\frac{2}{3} = -\frac{17}{3} \\3\frac{3}{4} = \frac{15}{4}[/tex]

Next, multiply the numerators (top numbers) by the denominators (bottom numbers)

The circumference of the circle = 17.8 units

The area of the circle = 25.1 square unit

Given,

the points are A(2,3) and B(4,1)

Formula to get the circumference of a circle = 2πr

Where r = radius of the circle

Radius of the given circle = Distance between the points A(2, 3) and

B(4, 1)

r = √(2 - 4)² + (3 -1)²

r = √(-2)² + (2)²

r = √4+4

r = √8

r = √2(4)

r = 2√2

Therefore the circumference is = 2π(2√2)

                                                = 17.77

                                                ≈ 17.8 units                                        

Area of the circle = πr²

                           = π(2√2)²

                           = 8π

                           = 25.13

                           ≈ 25.1 square unit

Hence we get the circumference and area of the circle as 17.8 units    and  25.1 square unit respectively.

We get the derivative of the function V = K x / k n + x as d v / d x = k / k n + 1.

We are given a function:

V = K x / k n + x

where K and k n are constants.

We need to find its derivative with respect to x

Derivative refers the rate of change of a function with respect to a variable.

Now differentiating with respect to x , we get that:

d V / d x = k / k n ( 1 ) + ( 1 )

d v / d x = k / k n + 1

Therefore, we get the derivative of the function V = K x / k n + x as d v / d x = k / k n + 1.

Step-by-step explanation:

inches: 0.5 miles: 14

inches: 1 mile 28

inches: 1.5 miles 42

The British imperial and American customary systems of measurement both use the inch as their standard unit of length (symbolized as in or ′′). It is equivalent to 1/36 of a yard or 1/ 12 of a foot. The term inch, which is often used to translate comparable units in other measurement systems and is derived from the Roman uncia ("twelfth"), is generally considered to refer to the breadth of the human thumb.

Since the international yard was adopted in the 1950s and 1960s, standards for the precise length of an inch have varied, but the inch is now based on the metric system and is defined as precisely 25.4 mm.

Since Building Brothers have been renovating homes for 16 years, the number of homes renovated is 24.

We can use mathematical operations of addition, subtraction, division, and/or multiplication to determine the missing value.

The first effort is converting 16 years into months.  The product is divided by 8 months to arrive at the quotient of 24 homes that were renovated within 16 years.

Time period = 16 years

Time spent to renovate a house = 8 months

12 months = 1 year

Total number of months spent = 192 months (16 x 12)

The number of renovations = 24 (192/8)

Thus, Building Brothers have renovated 24 homes within 16 years.
