Answer: 6x^2 - 12x - 21

Explanation:

h(x) = 2x^2 - 4x - 7
h(3x) = 3(2x^2 - 4x - 7)
h(3x) = 6x^2 - 12x - 21
Answer 2

Answer:

h(3x)=18x^2-12x-7

Step-by-step explanation:

[tex]h(x)=2x^2-4x-7\\h(3x) = ?\\\\h(3x) = 2(3x)^2 -4(3x)-7\\\\h(3x)=2\left(3x\right)^2-4\times\:3x-7\\\\h(3x)=3^2\times\:2x^2-4\times\:3x-7\\\\h(3x)=3^2\times\:2x^2-12x-7\\\\h(3x)=18x^2-12x-7[/tex]

The statement “1cm represents 2m” is the scale of the drawing. It can also be expressed as “1cm to 2m” or “1cm for every 2m.” What do you think the scale tells us?

Answers

Answer:

A scale is a way to resize drawings or figures to make them fit into a particular size.

Step-by-step explanation:

In 2D drawing or diagrams, a  scale factor greater than 1 enlarges the object, while a scale factor between 0 and 1 shrinks the objects, also using a scale factor of 1 changes nothing or leaves the drawing the way it is.

Furthermore, scales are represented in ratio form 1:2, telling us that say 1cm in the virtual environment or paper represents 2km in reality

To Find :

The height of the dock.

Solution :

This will make a right angle triangle as given in link below .

Now , applying Pythagoras theorem :

[tex](2h+3)^2=h^2+12^2\\\\4h^2+9h+9=h^2+144\\\\h^2+4h-45=0\\\\(h-5)(h+9)=0[/tex]

Step-by-step explanation: The x-factors are both -3 but the y-factors are different so you count the distance between them

Distance formula is
D= square root of x2-x1 squared plus y2-y1 squared

for (-3,5) and (-3,-9) that would be

Square root of -3- - 3 squared plus -9-5 squared

Answers

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.

Jamal borrowed 4000 to buy a used car he borrowed some of the money from a bank that charged 9.2% simple interest and the rest from a friend who charged 12% simple interest. If the total interest for a one year loan was 424.00 how much did jamal borrow at each rate

Answers

Answer:

2000 ; 2000

Step-by-step explanation:

Given the following :

Total amount borrowed = 4000

Total interést paid = 424

Simple interést = (principal * rate * time)

Rate 1 = 9.2% = 0.092

Rate 2 = 12% = 0.12

Let amount borrowed at 9.2% = x

Amount borrowed at 12% = y

x + y = 4000 - - - - (1)

x * 0.092 + y * 0.12 = 424

0.092x + 0.12y = 424 - - - - (2)

from (1):

x = 4000 - y

0.092(4000 - y) + 0.12y = 424

368 - 0.092y + 0.12y = 424

368 + 0.028y = 424

0.028y = 424 - 368

0.028y = 56

y = 56/0.028

y = 2000

x + y = 4000

x = 4000 - 2000

x = 2000

AYUDAA es para hoyyy Un avión volaba a 14.800 metros de altura . Primero , bajo a 23.000 decímetros y luego 54 hectometros más a qué altura en kilómetros vuela ahora ? EN ESPAÑOL LA RESPUESTA POR FAVOR Gracias

Answers

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.

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

What is a perpendicular line?

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.
