Write an exponential function whose graph contains the points (1, 6) and (0, 2).

12345 [234]

Answer:

y = 2 $(3)^{x}$

Step-by-step explanation:

The exponential function is of the form

y = a $(b)^{x}$

To find a and b substitute the given points into the equation

Using (0, 2), then

2 = a $(b)^{0}$ ⇒ a = 2

Using (1, 6), then

6 = 2 $(b)^{1}$ ⇒ b = 3

Equation is y = 2 $(3)^{x}$

Kobotan [32]

(88 + 92 + 96 + x) / 4 = 90
(276 + x) / 4 = 90
276 + x = 90 * 4
276 + x = 360
x = 360 - 276
x = 84 <=== he would need an 84

A man on the deck of a ship is 14 ft above water level. He observes that the angle of elevation of the top of a cliff is 40 degr

topjm [15]

Answer:

The distance of the ship from the cliff is 38.465 feet

The height of the cliff is 46.28 feet.

Step-by-step explanation:

As shown in the figure attached $d$ is the distance from the ship to the cliff, and $h$ is the height of the cliff from the ship.

From trigonometry

$tan(20^o)=\frac{14}{d}$

$d=\frac{14}{tan(20^o)}=38.465\:feet.\\\\\boxed{d=38.465ft}$

This is the distance to the cliff.

And we have

$tan(40^o)=\frac{h}{d}$

since $d=38.465ft$

$h=d*tan(40^o)=38.465*tan(40^o)=32.28ft$

Ad the height of the cliff is just $14+h$ or

$32.28+14=46.28 ft\\\\\boxed{height=46.28ft}$

Which is the height of the cliff.
