Answer:

<h3>x = 22.54</h3>

Step-by-step explanation:

Tangent θ = Opposite / Adjacent

tan(29) = 20/x

Cross multiply.

x = 20 / (tan(29))

x = 22.544284

1. Refer to the equation 3x − 4y = 12. (a) Create a table of values for at least 4 points.
Zinaida [17]

Answer: THE TABLE OF VALUES IS ATTACHED.

Step-by-step explanation:

Given the following equation:

3x-4y = 12

You can solve for the variable "y":

3x-4y = 12\\\\-4y=-3x+12\\\\y=\frac{3}{4}x-3

Now you can give values to "x" and substitute each into the equation to find the corresponding value of "y".

For x=-1:

y=\frac{3}{4}(-1)-3=-3.75

For x=0:

y=\frac{3}{4}(0)-3=-3

For x=1:

y=\frac{3}{4}(1)-3=-2.25

For x=2:

y=\frac{3}{4}(2)-3=-1.5

With this values you can make the table shown attached.

First second and last term of Ap are a,b,2a respectively, find its sum​
k0ka [10]

Answer:

  (3ab)/(2(b-a))

Step-by-step explanation:

The n-th term of an arithmetic progression is ...

  an = a1 +d(n -1)

Then the value of n is ...

  n = (an -a1)/d +1

The sum of an arithmetic progression is the product of the number of terms and the average of the first and last terms. In this sequence, the common difference d is ...

  d = (b -a)

So, the sum is ...

  Sn = (a +2a)/2·((2a -a)/(b -a) +1)

  Sn = (3ab)/(2(b-a)) . . . . sum of the arithmetic progression

__

<u>Example</u>:

The sequence 1, 1.5, 2 has ...

  a = 1, b = 1.5

Its sum is given by the above formula as ...

  Sn = 3(1)(1.5)/(2(1.5 -1)) = 4.5/(2(.5)) = 4.5 = 1 + 1.5 + 2 . . . . yes
