3 0

Answer:

Its the first choice.

Step-by-step explanation:

f(x) = 3^(x-1)

log₃ f(x) = (x-1)log₃ 3 log₃ 3 = 1 , so:-

log₃ f(x) = x - 1

x = log₃ f(x) + 1 Replace x by f-1(x) and f(x) by x, so:-

f-1(x) = log₃ x + 1

Let gbe a function such that g(x) = -2r + 5 and is defined on the domain (-1,3) State the range of this function in interval not

Paladinen [302]

Answer:

The range interval is: (7, -1)

Step-by-step explanation:

Given the function

g(x) = -2r+5

As the domain is (-1, 3)

Let us put the domain values in the interval (-1, 3)

Putting x = -1

g(x)=-2r+5

= -2(-1)+5

= 2+5

= 7

Putting x = 0

g(x)=-2r+5

= -2(0)+5

=0+5

= 5

Putting x = 1

g(x)=-2r+5

= -2(1)+5

=-2+5

= 3

Putting x = 2

g(x)=-2r+5

= -2(2)+5

=-4+5

= 1

Putting x = 3

g(x)=-2r+5

= -2(3)+5

=-6+5

= -1

Thus the range interval is: (7, -1)

A plane is at cruising altitude of 10,200 feet. If the angle of depression to the run way is 18 degrees, what is the distance, t

MatroZZZ [7]

Answer: $33,007.9\ ft$

Step-by-step explanation:

Given

The plane is cruising at an altitude of $h=10,200\ ft$

The angle of depression is $\theta=18^{\circ}$

Suppose the distance of the plane to the runway is x

from figure

$\Rightarrow \sin 18^{\circ}=\dfrac{h}{x}\\\\\Rightarrow \sin 18^{\circ}=\dfrac{10,200}{x}\\\\\Rightarrow x=33,007.9\ ft$
