Answer:

SinA=P/H

CosA=B/H

TanA=P/B

Hypotenuse=85

Perpendicular=13

Base=84

SinA=13/85

CosA=84/85

TanA= 13/84

A, E and B lie on a straight line segment.
Jobisdone [24]

The length of line BE on the given line segment is 3.5 m.

The given parameters:

  • <em>Length BD = 3 m</em>
  • <em>Length CD = 15 m</em>
  • <em>Length AB = 21 m</em>

<em />

The sketch of the given line segments is presented in the diagram uploaded.

The length of BE is determined by applying similar triangle theorem as follows;

\frac{CB}{AB} = \frac{BD}{EB} \\\\\frac{15 + 3}{21} = \frac{3}{EB} \\\\18EB = 63 \\\\EB = \frac{63}{18} \\\\EB = 3.5 \ m

Thus, the length of line BE on the given line segment is 3.5 m.

Given that f(x) = 4x+1/3, solve for f^-1(3)
sashaice [31]

Answer:

The value is 2/3

Step-by-step explanation:

In order to find this, we first need to find the inverse of the equation (f^-1). To do this, switch f(x) and x and then solve for the new f(x).

f(x) = 4x + 1/3

x = 4f(x) + 1/3

x - 1/3 = 4f(x)

1/4x - 1/12 = f(x)

f^-1(x) = 1/4x - 1/12

Now that we have the inverse function, we simply need to plug in 3 for x and we get the value we are searching for.

f^-1(x) = 1/4(3) - 1/12

f^-1(x) = 3/4 - 1/12

f^-1(x) = 9/12 - 1/12

f^-1(x) = 8/12

f^-1(x) = 2/3
