Answer:

h(1)=-13

h(n)=h(n-1)-13, n\geq 2

Step-by-step explanation:

We are given that

h(n)=-13n

We have to find the recursive formula of h(n).

Substitute n=1

h(1)=-13

n=2

h(2)=-13-13=-26=h(1)-13

n=3

h(3)=-13(3)=-39=-26-13=h(2)-13

h(4)=-13(4)=-52=-39-13=h(3)-13

:

:

:

h(n)=h(n-1)-13

Therefore, the recursive formula is given by

h(1)=-13

h(n)=h(n-1)-13, n\geq 2

Please answer this quick for me
nlexa [21]

Answer:

16/20

Step-by-step explanation:

We can write this as a proportion

4          x

----- = ----------

5          y

Using cross products

4y = 5x

We know that x+y = 36

We have 2 equations and 2 unknowns.

4y = 5x

x+y =36

Divide by first equation by 4

y = 5/4 x

substitute this into the 2nd equation

x + 5/4x = 36

Getting a common denominator

4/4x + 5/4 x = 36

Combining like terms

9/4 x =36

Multiply each side by 4/9 to isolate x

4/9 * 9/4x = 4/9*36

x = 16

Now we need to find y

y = 5/4x

y = 5/4 (16)

y= 20

The fraction is x/y

16/20

Can someone please help me I don’t understand how to do it
ira [324]

This problem requires multiple steps, so please read through the whole answer to get a good understanding on how to solve this problem

Step 1: Create an equation for the perimeter respect to x

The equation for the perimeter p is:

p=2w+2l where w is the width and l is the length

The length is 3x+4 and the width is 2x-1, so substitute these values into the equation:

p=2(3x+4)+2(2x-1)

=6x+8+4x-2

=10x+6

This is the equation for the perimeter

Step 2: Solve for x since we are given the perimeter

We are given that the perimeter is 96, thus we can create the equation:

10x+6=96

Subtract 6 from both sides

10x=90

Divide both sides by 10

x=9

We have now found the value of x

Step 3: Find the length and width now that we know x

Plug the value of x into the expressions for the length and the width that we are given

\text{Length}=3x+4=3(9)+4=31

\text{Width}=2x-1=2(9)-1=17

Step 4: Solve for the area now that we know the dimensions

This is probably the easiest step. Multiply the length and width to find the area:

31 \times 17=527

The area of the patio is 527.

I've double- and triple-checked that this is the correct answer, so do not worry about any errors.

Let me know if you need any clarifications, thanks!
