2.5, 0.5, 0.1, 0.02
2.5, 12.5, 62.5, 312.5
2.5, -2.5, -7.5, -12.5

Answers

Answer:

C

Step-by-step explanation:

I think

Answer:  C:  2.5, 12.5, 62.5, 312.5

Step-by-step explanation:

Let us remember that in a geometric sequence:

    ratio = [tex]\frac{a_{2} }{a_{1}}[/tex]

We know that [tex]a_{1}[/tex] (first term) is 2.5.  So plug in the numbers into the above formula:

    5 = [tex]\frac{a_{2} }{2.5}[/tex]

Multiply both sides by 2.5 to solve for [tex]a_{2}[/tex] (second term):

    5 × 2.5 = 12.5

By process of elimination, it is obvious the correct answer is C.

We can double check your answer by checking the rate is 5 by dividing:

   For example, 62.5 ([tex]a_{3}[/tex]) divided by 12.5 ([tex]a_{2}[/tex]) is appropriately 5.  

   Similarly, 312.5 ([tex]a_{4}[/tex]) divided by 32.5 ([tex]a_{3}[/tex]) is again 5, confirming our answer to be correct.

How many four-digit numbers can be created using the digits 0-9? Note: A number cannot be repeated for different digits.

10,000

Answers

6,561 is the right answer but good luck

5,040 four-digit numbers can be created using the digits (0-9).

Option B is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

There are 10 options for the first digit (0-9).

9 options for the second digit (since one digit is already used).

8 options for the third digit.

7 options for the fourth digit.

Therefore,

The total number of four-digit numbers that can be created is:

10 x 9 x 8 x 7 = 5,040

Thus,

5,040 four-digit numbers can be created using the digits (0-9).

Answer:

459

Step-by-step explanation:

If we break up the figure inot two parts, a rectangle and triangle, we can solve for the area. The area of the rectangle is 396 because the formula for a rectangle is LxW. The area for a triangle is 1/2BxH. So the area of the triangle would be 63. Add these up together and we get 459 centimeters squared.

C. 459 cm
Since we know the formula for the area of a triangle is A = b * h * .5, the area of the triangle is 63, and the area of the rectangle is 396. Add the two together and you get an area of 459cm.

Since the y-value decreases at the same rate as the x-value and has a negative slope, the expression that properly answers this question is y = -1x. Another thing taken into consideration is the y-intercept, which is zero, so you don't need to add anything to the initial equation.

Answers

Answer:

7m

Step-by-step explanation:

let the width of the garden be a

length of the garden =a+5

Area=L×W

14=(a+5)×a

14=a×a +5a

0=a×a +5a-14

0=a×a+7a-2a-14

0=a(a+7)-2(a+7)

0=(a-2)(a+7)

Either A-2=0. a=2

or a +7=0. a=7

width cannot be negative. so width=2m

length =a+5

which are "less than", "greater than", "less than or equal to", and "greater than or equal to" in that exact order. Choices A, B and D have one of these symbols which makes them inequalities.
