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.

kaheart [24]

Answer: A. 47

Step-by-step explanation: The answer would be 47 degrees because the 47 degree angle has one mark, and so does x and y. This means that these angles are the same.

Y=x^2 -9x at x = 4 Find an equation of the tangent an an equation of the normal
Montano1993 [528]

The tangent line to <em>y</em> = <em>f(x)</em> at a point (<em>a</em>, <em>f(a)</em> ) has slope d<em>y</em>/d<em>x</em> at <em>x</em> = <em>a</em>. So first compute the derivative:

<em>y</em> = <em>x</em>² - 9<em>x</em>   →   d<em>y</em>/d<em>x</em> = 2<em>x</em> - 9

When <em>x</em> = 4, the function takes on a value of

<em>y</em> = 4² - 9•4 = -20

and the derivative is

d<em>y</em>/d<em>x</em> (4) = 2•4 - 9 = -1

Then use the point-slope formula to get the equation of the tangent line:

<em>y</em> - (-20) = -1 (<em>x</em> - 4)

<em>y</em> + 20 = -<em>x</em> + 4

<em>y</em> = -<em>x</em> - 24

The normal line is perpendicular to the tangent, so its slope is -1/(-1) = 1. It passes through the same point, so its equation is

<em>y</em> - (-20) = 1 (<em>x</em> - 4)

<em>y</em> + 20 = <em>x</em> - 4

<em>y</em> = <em>x</em> - 24

PLZ HELP ME NEED THIS FAST WILL GIVE BRAINLIEST
OleMash [197]

Answer: l = 60 ft and w = 30 ft

P = 2(l + w)

180 = 2(l + w)

Let x = width of his yard

Let 2x = length of his yard

180=2(2x+x)

\frac{180}{2}=\frac{2(2x+x)}{2}

90=3x

\frac{90}{3} =\frac{3x}{3}

x=30ft

l = 2x = 30(2) = 60 ft

Check:

180 = 2(l + w)

180 = 2(60 + 30)

180 = 2(90)

180 = 180
