Answer:

The correct option is:

C. 2.29

Step-by-step explanation:

We are given a figure, we have to find tanB

tanB= \dfrac{Perpendicular}{Base}

tan(B)= \dfrac{AC}{AB}

substituting the values of AC and AB,we get

tan(B)=\dfrac{16}{7}=2.29

Hence,The correct option is:

C. 2.29

Answer:

Option C. tan(B)=2.29

Step-by-step explanation:

we know that

In the right triangle ABC

The tangent of angle B is equal to the opposite side angle B divided by the adjacent side angle B

tan(B)=\frac{AC}{AB}

substitute the values

tan(B)=\frac{16}{7}=2.29

If the average of x and y is 11 and the average of x, and y z is 5 what is the value of z
qwelly [4]

If the average of x and y is 11 and the average of x, y and z is 5, then the value of z is -7

Given,

The average of x and y = 11

We know average = Sum of the terms / Number of terms

Then, the equation will become

\frac{x+y}{2}=11
x+y =11×2

x+y =22

Average of x, y and z = 5

\frac{x+y+z}{3}=5

x+y+z = 5×3

x+y+z =15

Substitute the value of x+y

22+z=15

z =15-22

x = -7

Hence, If the average of x and y is 11 and the average of x, y and z is 5, then the value of z is -7

Help me please i need help
Mila [183]

Answer:

  A.  y = 2x -9

  B.  y = -1/2x +1

Step-by-step explanation:

The given line is in slope-intercept form

  y = mx + b

where m is the slope. For your given line, the slope is 2.

A. A parallel line will have the same slope. It is convenient to start with a point-slope form of the equation for the line:

  y = m(x -h) +k . . . . . for slope m through point (h, k)

You want the equation of the line through (4, -1) with slope 2, so its equation is ...

  y = 2(x -4) -1

Simplifying to slope-intercept form, this becomes ...

  y = 2x -8 -1

  y = 2x -9

___

B. A perpendicular line will have a slope that is the opposite of the reciprocal of the slope of the given line. That slope is ...

  m = -1/2

As above, the point-slope form of the perpendicular line is ...

  y = -1/2(x -4) -1

  y = -1/2x +1 . . . . . after simplification
