If BE is perpendicular to DF,that means that angle DEB is 90 degrees. Since we know that DEA is 71 degrees, subtract 90 to 71 to find the value for angle AEB. 90-71 equals 19 so angle AEBis 19 degrees.

A tourist purchases a car in england and ships it home to the united states. the car sticker advertised that the car's fuel cons
Valentin [98]

<u>Solution-</u>

Fuel consumption rate = 40 miles per UK gallon (As the car is manufactured in UK)

1 UK gallon = 4.5459631 lit

1 US gallon = 3.7853060 lit

\therefore \frac{1 \ UK \ gallon}{1 \ US \ gallon} = \frac{4.5459631}{3.7853060} = 1.2009499

\Rightarrow 1 \ UK \ gallon = 1.2009499 \ US \ gallon

As the fuel consumption rate = 40 miles per gallon

⇒ You need 1 UK gallon of fuel to go 40 miles

⇒ You need 1.2009499 US gallon of fuel to go 40 miles

Or you can say that, to go 40 miles you need 1.2009499 US gallon of fuel

⇒ To go 1 mile you will need  \frac{1.2009499}{40} = 0.0300237

⇒ To go 738 miles you will need 0.0300237×738 = 22.1574906 US gallon of fuel

∴ 22.1574906 gallon of fuel is actually required.

∴ But, what she thinks will require is \frac{738}{40} = 18.45 gallons (As she calculated using UK gallons)

The curve with equation y = f ( x ) is stretched so that the point (-3,-5) moves to the point (-3,-10). State in terms of f ( x
Leviafan [203]

Answer:

The transformed function is g(x) = 2\cdot f(x), \forall\,x \in \mathbb{R}.

Step-by-step explanation:

Let be f(x) and g(x) continuous functions in x. In this case, the stretch factor consist on multiplying f(x) by a scalar factor, so that:

g(x) = k \cdot f(x), \forall\, k\in \mathbb{R}, k \neq 0

The stretch factor is:

k = \frac{g(x)}{f(x)}, \forall\, x \in \mathbb{R}

If f(-3) = -5 and g(-3) = -10, then:

k = \frac{g(-3)}{f(-3)}

k = \frac{-10}{-5}

k = 2

The transformed function is g(x) = 2\cdot f(x), \forall\,x \in \mathbb{R}.
