From the figure we conclude
Let X = tree height, using similar triangles 
<span>X/120 = 160/(2*120) </span>

<span>X = 160*120/240 </span>
<span>X = 80 ft
</span>hope it helps

If h(x) = │5x - 17│, find h(3).
arsen [322]

Answer:

2

Step-by-step explanation:

5x - 17

5(3) - 17 = 15 - 17 = -2

However, there is an absolute value sign over the expression. Abs value makes negatives turn positive. So -2 becomes 2.

One number is 8 times a first number. A third number is 100 more than the first number. If the sum of the three is 690, find the
mezya [45]
<h3>Given</h3>

Three numbers are n, 8n, and (100+n).

Their total is 690.

<h3>Find</h3>

the three numbers

<h3>Solution</h3>

n + 8n + (n+100) = 690

10n + 100 = 690 . . . . . . . simplify

10n = 590 . . . . . . . . . . . . subtract 100

n = 59

8n = 472

n +100 = 159

The three numbers are 59, 472, and 159.

Binomial distribution,

n = 36 independent events,

p = 0.5 probability of success and of failure, as 1-p = p.

Mean of binomial distribution is np=18.

Variance is np(1-p)=9

Standard deviation is sqrt(variance)=3.

Which absolute value function defines this graph?
Yuki888 [10]

The vertex of the graph is at (-2, 3).

This means the equation is of the form f(x)=a|x+2|+3.

Substituting in the coordinates of one of the other points on the graph that is not the vertex, such as (-1, -1),

-1=a|-1+2|+3\\\\-1=a+3\\\\a=-4

So, the equation is \boxed{f(x)=-4|x+2|+3}
