<h3>Answer: -10</h3>

Work Shown:

f(n) = f(n-2)*f(n-1)

f(3) = f(3-2)*f(3-1)

f(3) = f(1)*f(2)

f(3) = -2*5

f(3) = -10

Write the recursive formula and the explicit formula for the sequence {-15,-7,1,9, 17,...}.

olchik [2.2K]

ANSWER

Explicit formula:

$a_n= 8n - 23$

Recursive

$a_{n}= a_{n - 1} + 8,a_1=-15$

EXPLANATION

The first term of the sequence is

$a_1=-15$

The common difference is

$d = - 7 - - 15$

$d = 8$

The nth term is given by the formula,

$a_n=a_1 + d(n - 1)$

$a_n= - 15+ 8(n - 1)$

$a_n= - 15+ 8n -8$

The explicit formula is;

$a_n= 8n - 23$

The recursive definition is

$a_{n}= a_{n - 1} + 8,a_1=-15$

Use the diagram below to solve for x and y.

Mrac [35]

Answer:

Option A. x=30,y=42

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles ABC and ZYX have three congruent interior angles

therefore

Triangles are similar

step 1

Find the value of x

$\frac{ZY}{AB}=\frac{ZX}{AC}$

substitute the values

$\frac{20}{x}=\frac{12}{18}$

$x=20*18/12=30\ units$

step 2

Find the value of y

$\frac{ZY}{AB}=\frac{XY}{CB}$

substitute the values

$\frac{20}{30}=\frac{28}{y}$

$y=30*28/20=42\ units$

Solve for A.................<br><br> H= A/2

grigory [225]

Step-by-step explanation:

First, multiply each side of the equation by

to eliminate the fraction while keeping the equation balanced:

2×A=2×h2(a+b)

2A=2×h2(a+b)

2A=h(a+b)

Now, divide each side of the equation by

to solve for

while keeping the equation balanced:

2Aa+b=h(a+b)a+b

2Aa+b=h

h=2Aa+b
