Take DEBC a parralelogram
Parralel sides are DE and BC
THEREFORE,
1/2*(a+b)*h
1/2*(6+15)*h
1/2*(21)*h=0
10.5*h=0
h=-10.5
Answer:
It's B. 5√13 / 13.
Step-by-step explanation:
Multiply top and bottom of the fraction by √13:
5 * √13
= -------------
√13 * √13
= 5√13 / 13.
Answer:
x = -1.4 and x=2
Step-by-step explanation:
The solutions are where the graphs intersect
The graphs appear to intersect at x = -1.4 and x=2
Answer:
acd and bcd are similar triangle
ac/cb = ad/db
3/4 =2.25/x
x=3
The Fibonacci sequence is a series of numbers where a number is found by adding up the two numbers before it. Starting with 0 and 1, the sequence goes 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so forth. Written as a rule, the expression is xn<span> = x</span>n-1<span> + x</span>n-2<span>.
</span>A recursive sequence<span> , also known as a recurrence</span>sequence<span>, is a </span>sequence<span> of numbers indexed by an integer and generated by solving a recurrence equation. The terms of a </span>recursive sequences<span> can be denoted symbolically in a number of different notations, such as , , or f[ ], where is a symbol representing the </span>sequence<span>.
