To find the area of the rectangle, do A=lw which is 4x13=52. to find the area of the triangle, first find the height. this is 13-6=7. now do A=bh/2 which is (5x7)/2=17.5. 17.5+52=69.5 which is your answer. DONT OPEN ANY LINKS ON HERE, ITS A VIRUS

First you calculate the area of the rectangle.
It‘s simply one side times the other side.

In your task this would be:
4ft x 13ft = 52 square ft

Now you have to calculate the area of the triangle. The formula for this is: Height x Length of the base x 1/2

So in your task this would be:
7ft x 5ft x 1/2 = 17.5 square ft

(you get the 7ft by subtracting 6ft from 13ft, which results in the height of the triangle)

Now you just add those two surfaces areas together:
52 square ft + 17.5 square ft = 69.5 square ft

Which recursive formula can be used to generate the sequence below, where f(1) = 3 and n ≥ 1? 3, –6, 12, –24, 48, … f (n 1) = –3

Maslowich

The recursive formula will be equal to f(n + 1) = –2 f(n).

The complete question is given below:-

Which recursive formula can be used to generate the sequence below, where f(1) = 3 and n ≥ 1?

3, –6, 12, –24, 48, …

f (n + 1) = –3 f(n )

f (n + 1) = 3 f(n )

f (n + 1) = –2 f(n )

f (n + 1) = 2 f(n)

<h3>What is a function?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

The recursive formula for this sequence is calculated as we will put the different values of n to find the values of the function in the series.

n = 1

f(n) = 3

n = 2

f(2) = -2 (3) = -6

n = 3

f(3) = -2 (-6) = 12 and so on

Therefore the recursive formula will be equal to f(n + 1) = –2 f(n).

Needing help with these 2 problems

UNO [17]

Answer:

15) 3.2

17) 13.4

Step-by-step explanation:

To find the missing lengths, you need to use the Pythagorean theorem:

a² + b² = c²

In this form, "c" represents the length of the hypotenuse and "a" and "b" represent the lengths of the other two sides.

You are trying to find one of the side lengths (not the hypotenuse) in 15). To find the other length, you can plug the other values into the equation and simplify to find "b".

15) a = 4.1 c = 5.2

a² + b² = c² <----- Pythagreom Theorem

(4.1)² + b² = (5.2)² <----- Plug values in for "a" and "c"

16.81 + b² = 27.04 <----- Raise numbers to the power of 2

b² = 10.23 <----- Subtract 16.81 from both sides

b = 3.2 <----- Take the square root of both sides

You are trying to find the hypotenuse in 17). Since you have been given the lengths of the other sides, you can plug them into the equations and simplify to find "c".

17) a = 4.4 b = 12.7

a² + b² = c² <----- Pythagreom Theorem

(4.4)² + (12.7)² = c² <----- Plug values in for "a" and "b"

19.36 + 161.29 = c² <----- Raise numbers to the power of 2

180.65 = c² <----- Add

13.4 = c <----- Take the square root of both sides
