The difference in altitude between a mountain that has an altitude of 2593feet and a desert valley that is 394feet below sea level is

dA=2987feet

Generally, the equation for the difference  is  mathematically given as

dA= mountain  altitude -  desert valley

Therefore

dA=2593-(-394)

dA=2593+394

dA=2987feet

In conclusion, The height of a mountain that is located at an elevation of 2593 feet compared to the elevation of a valley in the desert that is 394 feet below sea level is the difference in altitude.

Answer:

Draw a line going down from the 300, with a break in the middle and finish it out at the 6 hr mark.

Step-by-step explanation:

Start at the 300 and draw that line down to the 180 mark lined up with the 2 hour dot. Then draw a horizontal line from there to the middle of the 2 and the 4. Then draw a line from where you ended the break with the same slope as the beginning.

The degrees of the whole segment is 90 because we know that a right angle is 90 degrees and can be shown with a square in the corner. One angle inside the 90 degrees is 50 degrees and the other two values are the same. Since 90 - 50 = 40, we know that the remaining is 40 degrees. Since x is the same, we divide 40 by 2, getting 20 degrees.

ANSWER: x = 20 degrees

Step-by-step explanation:

The quadratic equation, x(2) + 2 =420 can be used to find x.

you can use trial and error

x(2) + 2 =420

210(2)=420 but we need to add the two so lower the [tex]120[/tex]

209(2)=418+2 = 420

so, the x value must less than 21.

A quadratic equation with variable x is written in standard form as [tex]ax2 + bx + c = 0[/tex], where a, b, and c are constants such that the value of an is non-zero but the values of b and c can both be zeros.

Let's change [tex]ax2 + bx + c = 0[/tex] from its standard form to its vertex form, which is [tex]a (x - h)2 + k = 0[/tex], where (h, k) is the vertex of the quadratic function [tex]f(x) = a (x - h)2 + k[/tex]. Keep in mind that 'a' has the same value in both equations. Just set them equal so we can determine how the variables relate to one another.

Answer:

Yes, the cube root of a negative number can be calculated.

Step-by-step explanation:

The distance between the given points P(-7,8) and J(-3,1) is √65 = 8.06225775

Given that, The points are P=(-7,8) and J = (-3,1).

A coordinate plane is a surface formed by two dimensional lines .

The distance between the points is calculated using the distance formula that is, distance between A(x1,y1) and B(x2,y2) is,

√[(x2-x1)²+(y2-y1)²], by using this formula you can find the distance between any two points on the plane.

Therefore the distance between the given points P and J is ,

  PJ = √[(-3+7)²+(1-8)²]

       = √[(4)²+(-7)²]

       = √[(16) + (49)]

       = √[16+49]

       = √[65]

       = 8.06225775

PJ = 8.06225775

Therefore the distance between the given points P(-7,8) and J(-3,1) is 8.06225775

An equation which is parallel to 4x - 6y = -36 passing through points (2, 3) is y = 2x/3 + 5/9.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

In Geometry, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts.

This ultimately implies that, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m is the slope.

Simplifying the equation, we have:

4x - 6y = -36

6y = 4x + 36

Dividing both sides by 6, we have:

y = 2x/3 + 6

m₁ = m₂ = 2/3.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

At point (2, 3), we have:

y - 3 = 2/3(x - 2)

y - 3 = 2/3(x - 2)

y - 3 = 2x/3 - 4/3

y = 2x/3 - 4/3 + 3

y = 2x/3 + 5/9

The average speed was 60[tex]\frac{k+300}{96+t}[/tex]

We are given that a plane travelled k miles in 96 minutes. Since we need the average speed in miles per hour we can convert 96 minutes to hours.

96 minutes = 96/60 =8/5 hours

We are also given that the Plane completed the remaining 300 miles in t minutes. We must also convert t minutes to hours.

t minutes = t/60 hours

Now we can calculate the average speed for the entire trip, using the formula for average speed.

Average Speed = total distance/ total time

Average Speed = (k +300)/(8/5 + t/60)

Average speed = (k + 300) / ((96 + t)/60)

Hence, Average Speed = 60(k + 300)/ (96 + t)

Answer: 14,825 is the answer

Step-by-step explanation:

Answer: 14,825

Step-by-step explanation:

its easy.

The total time they will be driving the second day is 8 hours

The total distance they are planning to go  = 900 miles

Distance travelled on first day = 420 miles

Distance yet to be  travelled on second day = Total distance - distance covered = 900 miles- 420 miles= 480 miles

The speed of the car = 60 miles per hour

60 miles of distance covered in time = 1 hour

1 mile of distance covered in time = 1 hour /60 miles = 1 minute

This is solved using Unitary Method

1 hour = 60 minutes

480 miles can be covered in time = 1 minute × 480 miles

                                                         = 480 minute

                                                         =8 hours

Hence, The total time they will be driving the second day is 8 hours

Distance and displacement are two quantities that appear to mean the same thing but have very different meanings and definitions. Distance is defined as "how much ground an object has covered during its motion," whereas displacement is defined as "how far out of place an object is."

Distance is defined as an object's total movement without regard for direction. Distance can be defined as how much ground an object has covered regardless of its starting or ending point.

It is not necessary for the increment to be the same for both the x and y values.

The following conclusion may be drawn from an equation: both the x and y exponents should be set to 1.

Answer:

Step-by-step explanation:

a) this graph is that of a parabola that opens up.  As is the case for all parabolas, the domain is the set of all real numbers.  The range begins with the smallest y-value, which is -4, extending upwards from there:  [-4, infinity)

b) this graph's shape most closely resembles that of a polynomial; as we move from left to right, y increases, reaches a local maximum, decreases to a local minimum, and then continues to increase with x.  As is the case for all polynomials, the domain is the set of all real numbers.  As we move from x = 0 to the left, y decreases without bound; from x ≥ 12 onward, y increases without bound; thus, the range is (-infinity, +infinity).

c) The graph represents a quarter of an ellipse for which x begins at -40 and ends at [4, -16].  Thus, the domain is [-40, 4].  By inspection we see that the smallest y value is -16 and the largest is 4; thus, the range is [-40, 4].
