Answer:

Arithmetic

Step-by-step explanation:

The sequence is arithmetic because it goes up by a constant rate of 5.

You can tell if a sequence is arithmetic if it goes up or down by a constant rate.

A sequence is geometric if it is divided or multiplied by a number at a constant rate.

If there is no constant rate, then the sequence would be neither.

How do you solve this

dolphi86 [110]

Answer:

3.76 × 10^4

Step-by-step explanation:

1. Work out what they are.

1.26 × 10^4 = 12600 (check your calculator to see if I'm right)

To get this, I multiplied 1.26 by 10,000. This is because 10^4 is 10000 (it has 4 zeros). Or you could move the decimal point forward 4 spaces.

2.50 × 10^4 = 25,000

By doing the same thing above.

2. Add them together

12,600 + 25,000 = 37,600

3. Change the answer into its scientific notation

To do this we need to divide 37,600 by a number to make it less than 10, but still keeping the digits. This always ends in zeros by the way (e.g. 100, 1,000, 100,000).

37600 ÷ 10,000 = 3.76

Scientific notations always have times 10 to the power of something (× 10^x). So we put that in:

3.76 × 10^x what is x?

x is the number of of times you multiply by 10 to get back to 36700. This is 4 times.

(This is the same as multiplying by 10,000 as it has 4 zeros. This is also the same as moving the decimal point 4 spaces)

So your final answer is: 3.76 × 10^4

How do i Simplify 252 ÷ 3-3(4)(1)?

vivado [14]

9514 1404 393

Answer:

Step-by-step explanation:

Enter the expression into your calculator.

If you're doing this by hand, follow the Order of Operations. The expression is the difference of a quotient and a product. The quotient is on the left, so it is figured first.

252÷3 = 84

The product is figured next.

3(4)(1) = 12(1) = 12

Then the difference is figured:

84 -12 = 72

The simplified result is 72.

30 points

s2008m [1.1K]

Answer:

A: You plot these points (-3,4) (-3,6) (-5,6) (-7,4)

B: The transformation would be described as a reflection over the y axis

C: The transformation does result in a congruent figure because the shape doesn't change in size or shape and in length or width

Step-by-step explanation:

So our plots from the figure are: (3,4) (3,6) (5,6) (7,4)

So using the rule (x, y) → (-x, y) are new points would be:

(-3,4)

(-3,6)

(-5,6)

(-7,4)

This rule (x, y) → (-x, y) is used for the type of transformation that is a reflection but over the y axis.
