Answer:

Dominio de una Raíz cuadrada

Cuando tenemos una raíz, para estudiar su existencia debemos saber que una raíz existe si y solo sí el radicando (lo que está dentro de la raíz) sea mayor o igual a cero.

Por lo tanto deberemos estudiar el signo de lo que se encuentra dentro de la raíz; y determinar las zonas positivas y las raíces que son las zona de existencia de la función raíz o dominio de esta función.

On a map, the distance between two towns is 3.4 inches. The map scale is 2 inches: 25 miles. What is the actual distance between

Mariulka [41]

For this question we can solve it by setting up a proportion:

$\frac{2inches}{25 miles}= \frac{3.4inches}{x}$

Now we can solve for x to find the total distance between the towns. Let's cross multiply and solve for x:

$2x=85$
$x=42.5miles$

So now we know that the total distance between the towns is 42.5 miles.

Answer:

106 m

Step-by-step explanation:

The law of sines is useful.

The angle opposite the given side of 50 m is ...

180° -83° -69° = 28°

Then the distance (d) opposite the 83° angle is ...

d/sin(83°) = (50 m)/sin(28°)

d = (sin(83°)/sin(28°))×(50 m) = 105.709 m

The ball is about 106 meters from the pin.

Suppose you invest $2,500 in a fund earning 10% simple interest annually. After two years you have the option of moving your mon

Anon25 [30]

Answer:

account after 2 years of simple interest at 10%: (2,500 * 0.10 * 2) + 2500 = 3,000

Note that simple interest only pays interest on the original balance, NOT on the accrued (paid) interest....

a) 5 more years at 10% simple: (2500 * 0.10 * 5) + 3,000 = $4,250

5 years compound interest on $3k: 3,000(1.07^5) = $4,207.66

b) TOTAL of 10 years

simple interest: (2500 * 0.10 * 10) + 2500 = 5,000

compound interest: only 8 years remain of the total 10 year time horizon

3000(1.07^8) = $5,154.56
