Answer:

7.1 km or 7.1 kilometer

Step-by-step explanation:

Esta pregunta se resuelve mediante la conversión de unidades SI. Nuestra respuesta final será en kilómetros, por lo tanto, estamos convirtiendo todos los valores dados a kilómetros.

De la pregunta, tenemos la siguiente información:

Altura de vuelo actual del avión = 14.800 metros

1 metro = 0.001 kilómetro

14,800 metros =

14,800 × 0.001

= 14.8 kilómetros

Avión que descendió primero = 23.000 decímetros

1 decímetro = 0.0001 kilómetro

23,000 decímetros =

23,000 × 0.0001 kilómetro

= 2.3 kilómetros

Descendió la segunda vez = 54 hectómetros más

1 hectómetro = 0.1 kilómetro

54 hectómetros =

54 × 0.1 kilómetro

= 5.4 kilómetros

Por lo tanto, la altura en kilómetros que vuela el avión ahora se calcula como

14.8 km - 2.3 km - 5.4 km

= 14.8 km - (2.3 km + 5.4 km)

= 14.8 kilometros - 7.7 kilometros

= 7.1 kilometros

Por lo tanto, el avión vuela actualmente a 7.1 km o 7.1 kilómetros.

Answer:

12/25

Step-by-step explanation:

0.48 is read as "forty-eight hundredths," so we can write it as a fraction as

48/100.

Since both 48 and 100 have a common factor, we can reduce the fraction.

48 and 100 are both divisible by 4.

48/100 = 12/25

There are no common factors of 12 and 25, so 12/25 is the answer.

Answer:

12/25

Step-by-step explanation:

48/100 Divide by 2

24/50 Divide by 2 again

12/25 Can not be further simplified.

Answer:

A. The initial value of the graph is 200. The graph increases by a factor of 1.05 per 1 unit increase in time.

Hope this helps!

Step-by-step explanation:

The initial value of the graph is 200. The graph increases by a factor of 1.05 per 1 unit increase in time the graph of the exponential function relate to time and money.

Given that,

Leticia invests $200 at 5% interest.

If y represents the amount of money after x time periods.

We have to determine,

Which describes the graph of the exponential function relating time and money?

According to the question,

The graph represents the exponential function relating time and money.

Where y represents the amount of money after x time periods.

After 1 period the amount of money is,

[tex]\rm f(x) = 200 + 200\left(\dfrac{5}{100}\right)\\\\f(x) = 200(1+0.5)\\\\f(x)= 200(1.5)\\\\[/tex]

After 2 periods the amount is,

[tex]\rm f(x) = 200(1.5) \times (1.5)\\\\f(x) = 200. (1.5)^2[/tex]

After 3 periods the amount is,

[tex]\rm f(x) = 200(1.5)^2 \times (1.5)\\\\f(x) = 200. (1.5)^3[/tex]

Therefore,

The amount after x period is,

[tex]\rm f(x) = 200(1.5)^x[/tex]

The initial value is when x = 0,

[tex]\rm y = 200 (1.05)^0 \\\\y = 200\times 1\\\\y = 200[/tex]

And the increasing factor is 1.05 because any value is the previous one times 1.05.

Hence, The initial value of the graph is 200. The graph increases by a factor of 1.05 per 1 unit increase in time the graph of the exponential function relate to time and money.

Answer:

30

Step-by-step explanation:

Hope this will help:)

The numerical length of line segment NP will be 30 units.

A line segment in mathematics has two different points on it that define its boundaries.

A line segment is sometimes referred to as a section of a path that joins two places.

Point O is on line segment NP.

Given NP = 4x + 10, NO = 4x, and OP = x + 5.

We know that for a line segment.

PN = PO + ON

4x + 10 = 4x + x + 5

x = 5

Then the numerical length of line segment NP will be

NP = 4x + 10

NP = 4(5) + 10

NP = 20 + 10

NP = 30

Then the numerical length of line segment NP will be 30 units.

Answer:

Points N and K are on plane A and plane S.

Point P is the intersection of line n and line g.

Points M, P, and Q are noncollinear.  

e2020

Step-by-step explanation:

According to the given diagram of Intersecting planes, Option (1), Option (3), Option (4) are True.

A plane is a two-dimensional, flat surface that stretches indefinitely.

A point is said to lie on a plane when it satisfies the equation of plane which is ax^3 + bx^2 + cx+ d = 0 and sometimes it is just visible in the figure whether a point is lying on a plane or not.

In Option(1) : Points N and K are lying on the line of intersection of plane A and S and will satisfy the equation of both planes.

In Option(2) : Point P is lying on both planes B and S, but the point M is lying only on plane B, hence this option is wrong.

In Option(3) : It is clearly visible the Point P is the point of intersection of lines n and g.

In Option(4) : It is clearly visible that Points M,P,Q are not lying on the same line, hence they are non-collinear.

In Option(5) : Line d intersects the plane A at point L and not point N, hence this is also wrong.

Hence the correct options are 1,3,4.

B. Perpendicular rays

Step-by-step explanation:

Definition Perpendicular: Perpendicular lines, rays, or segments intersect at right angles. If lines, rays, or segments are perpendicular, then they are right angles. If lines, rays, or segments intersect. at right angles, then they are. perpendicular.

Hope this Helps

The rays that intersect at a right angle are perpendicular rays option (B) is correct.

Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.

As we know,

From the definition, the perpendicular lines are the lines that intersect at right-angle or 90 degrees.

Two rays that intersect at a right angle are perpendicular rays.

Thus, the rays that intersect at a right angle are perpendicular rays option (B) is correct.
