12) You can exchange $5 US dollars for L123 Honduran Lempiras. How many dollars can you exchange L2,300 for? ----

Anit [1.1K]

Step-by-step explanation:

$5 US dollar = L123 Honduran Lempiras

L2300Honduran Lempiras = x ( Let $ be x)

By using chain rule, we get

5×2300 = 123×x

or, 11500 = 123x

or, x = 11500÷123

hence, x = 93.49593496

A sequence is defined by the recursive formula f(n + 1) = 1.5f(n). Which sequence could be generated using the formula? –12, –18

Softa [21]

Answer:

The sequence -12 , -18 , -27 , ............ is generated using the formula ⇒ 1st sequence

Step-by-step explanation:

The recursive formula of the sequence is f(n + 1) = 1.5 f(n)

That means there is a constant ratio 1.5 between each two consecutive terms

In sequence -12 , -18 , -27 , ............

The first term is -12

The formula is f(n + 1) = 1.5 f(n)

Use the first term where n = 1 to find the 2nd term

∵ f(1) = -12

- Substitute n by 1 in the given formula

∵ f(1 + 1) = 1.5 f(1)

∴ f(2) = 1.5(-12)

∴ f(2) = -18

Use the second term where n = 2 to find the 3rd term

∵ f(2) = -18

- Substitute n by 2 in the given formula

∵ f(2 + 1) = 1.5 f(2)

∴ f(3) = 1.5(-18)

∴ f(3) = -27

∴ The sequence -12 , -18 , -27 , ............ is generated using the formula

Nataly_w [17]

$284.99 - 4194.99 = $89.98
$89.98 ÷ 2 = $ 44.99

Answer:

option b 5√2

option a 20

option c 4

option d 3/4

option b 3

Step-by-step explanation:

To solve all these questions we will use trigonometry identity which says that

sinΔ = opposite / hypotenuse

1)

sin45 = 5 / KL

Kl = $\frac{5}{\frac{\sqrt{2}}{2} }$

KL = 5√2

2)

TanФ = opp / adj

Ф = Tan^-1(5/14)

Ф = 19.65

≈ 20

3)

sin(30) = rq / 8

rq = sin(30)(8)

rq = 4

4)

tan(Ф) = 6/8

5)

angle 3
