Answer:

8/45 or 0.177...... (the seven continues forever).

Step-by-step explanation:

8/9 ÷ 5

First, turn 5 into a fraction. That will be 5/1

8/9 ÷ 5/1

When you're dividing fractions, you flip the second fraction and turn the division sign to a mutiplication sign

8/9 ÷ 1/5

8/9 * 1/5

Now you multiply. We will multiply the numerator and then the denominators through since there are no common factors.

8 * 1/9 * 5

8/45

The width of the given trampoline is 9 feet, and which area is 135 square feet.

The area of a rectangle is defined as the product of the length and width.

The equation w² +6w -135 = 0 can be factored as (w+15)(w-9) = 0.

Therefore, the solutions for w are w = -15 or w=9.

Since the width of the trampoline cannot be negative, we can conclude that the width of the trampoline is 9 feet.

To confirm this, we can calculate the length of the trampoline using the given information that the length is 6 feet greater than the width:

length = width + 6 = 9 + 6 = 15 feet

Then we can verify that the area is indeed 135 ft²:

area = length x width = 15 x 9 = 135 ft²

Therefore, the width of the trampoline is 9 feet.

Answer:

a = 8, b = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given the exponential function

f(x) = a[tex]b^{x}[/tex]

To find a and b use the given coordinate points on the graph

Using (0, 8 ), then

8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then

a = 8

f(x) = 8[tex]b^{x}[/tex]

Using (2, 18 ) , then

18 = 8b² ( divide both sides by 8 )

[tex]\frac{18}{8}[/tex] = b² , that is

b² = [tex]\frac{9}{4}[/tex] ( take the square root of both sides )

b = [tex]\sqrt{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex]

Thus

f(x) = 8[tex](\frac{3}{2}) ^{x}[/tex]

can i be brainiest...

Answer:

the answer is 14y

Step-by-step explanation:

this is because if you multiply 2xy it is 2y then multiply 2x3 and that's 6. Then you add 6+2y and get 8y. Next you multiply 2x4 which is 8 then 2xy which is 2y. Next you subtract 8-2y which is 6y. then you add 6y+8y and you answer is 14y.

Answer:

10^4 or 10000

Step-by-step explanation:

The multiplication of 10x 10 x 10 x 10 is 10000.

We have given that the

10x 10 x 10 x 10

We have to find the multiplication of the above 10.

Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division.

here we have

10 x10=100

10x100=1000

10x1000=10000

Therefore the multiplication of 10x 10 x 10 x 10 is 10000.
