What is the length of AC¯¯¯¯¯ ?

Mathematics

Answer:

AC = 6

Step-by-step explanation:

y is the dimension of the horizontal segment (see the attached image).

The hypotenuses are the same dimension, so:

(x+4)^2=(x/2)^2+y^2

(3x-8)^2=(x/2)^2+y^2

So,

(x+4)^2 = (3x-8)^2

x+4 = 3x-8

x-3x = -8-4

-2x = -12

x = 6

And x is the dimension of the segment AC.

Answer : The length AC is, 6

Step-by-step explanation :

The given triangle is an isosceles triangle in which the angles opposite to equal sides are always equal.

Thus, \angle A=\angle C

(x+4)=(3x-8)

x+4=3x-8

3x-x=8+4

2x=12

x=6

The length AC = x = 6

The length AB = (x + 4) = 6 + 4 = 10

The length AB = (3x - 8) = 3(6) - 8 = 10

Thus, the length AC is, 6

Find the sum of the first 20 terms of the arithmetic sequence 4, 10, 16, 22....
hammer [34]

n = 20

d = 6

a = 4

L = a + (n - 1)*d

L = 4 + (20 - 1)*6

L = 4 + 19*6

L = 118

Sum = (a + L)*n/2

Sum = (4 + 118) * 20/2

Sum = 122 * 10

Sum = 1220

I need help ? which linear function is represented by the graph?​
PilotLPTM [1.2K]
<h3>Answer: f(x) = (-1/2)x+1, choice B</h3>

=================================================

Explanation:

The diagonal line passes through 1 on the vertical y axis. So the y intercept is b = 1. This means the location of the y intercept is (0,1).

Start at (0,1) and move down 1 and to the right 2 to arrive at (2,0). This is another point on the diagonal line. The motion of "down 1 and right 2" is effectively the slope

slope = rise/run = -1/2

rise = -1, run = 2

The rise being negative means we have gone downhill as we move to the right.

With m = -1/2 as the slope and b = 1 as the y intercept, we go from y = mx+b to y = (-1/2)x+1

The last thing to do is replace y with f(x) to get f(x) = (-1/2)x+1 as the final answer.

Find the rate of change: Mike can bike 3 miles in an hour. What is the speed at which mike can bike?
masya89 [10]
Rate  of  change=<span><span>change  in  y divided by </span><span>change  in  <span>x
y= 3,6,9
x= 1,2,3
The numbers chosen above are because if mike travels 3 miles in one hours then he can travel 6 miles in two hours and 9 miles in 3 hours. 
Change in y = 3
Change in x = 1
3 / 1 = 3
So, the rate of change is 3.</span></span></span>
