Answer:

The length of  bank side ,s = \sqrt{3} unit.

The length of hypotenuse, h= 2 unit.

Step-by-step explanation:

Given in 30-69-90 triangle

We know that

tan\theta= \frac {perpendicular}{base}

sin\theta=\frac { perpendicular}{ hypotenuse}

When\theta=30^{\circ}

sin\theta= \frac{1}{h}

sin30^{\circ}=\frac {1}{h}

sin30^{\circ}=\frac{1}{2}

Therefore,\frac{1}{h} =\frac{1}{2}

By cross multiply we get

h=2

tan30^{\circ}=\frac{1}{s}

tan30^{\circ}=\frac {1}{\sqrt{3}}

\frac{1}{s} =\frac{1}{\sqrt{3}}

By cross multiply we get

s=\sqrt{3}

Hence, the length of side of bank, s=\sqrt{3} unit

Length of hypotenuse ,h=2 unit.

What is the inverse function of d(x) = 2x - 4?
Naddik [55]
Let d(x) = 2x - 4

Or

y = 2x - 4

We have replace x = y

x = 2y - 4

Now Isolate "y"

x + 4 = 2y

Pass "2" dividing

(x + 4) / 2 = y

y = x/2 + 2

Or

d(x)^-1 = x/2 + 2

After the first term in a sequence, the ratio of each term to the preceding term is r. If the first term is a, what is the third
irinina [24]

Answer:

The 3rd term is

ar^2

Step-by-step explanation:

From the given information, the first term of the sequence is

a_1=a

The common ratio of the sequence is

r

The explicit formula for a geometric sequence is :

a_n=a_1(r^{n-1})

To find the third term, we put n=3 to get:

a_n=a(r^{3-1})

This simplifies to:

a_3=ar^2
