Is 10.75 a rational or an irrational number?

2 answers:

10.75 is a rational number. Although it is a decimal so the 'can be made into a fraction with two whole numbers' thing may not seem to apply to this number it actually does because 75 can divide evenly into 5, therefore i can be reduced down into a whole number :-)

10.75 is a rational number because it does not have a repeating decimal.

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years,

snow_lady [41]

Answer:

y = 500(1.05)^x.

Step-by-step explanation:

551.25 = 500x^2 where x is the multiplier for each year.

x^2 = 551.25/500

x = 1.05

So the value after x years is 500(1.05)^x.

The table shows the outputs, y, for different inputs, x: Input (x) 6 12 15 25 Output (y) 14 15 15 16 Part A: Do the data in this

cluponka [151]

Answer:

Part A: No it is not a function

Part B: The equation

Part C: x = 3

Step-by-step explanation:

Part A - The table:

Input (x) Output (y)

6 14

12 15

15 15

25 16

This is a function because it has no repeating inputs values which have alternate outputs. Each input is assigned exactly one output.

Part B - The relation y = 7x - 15 has the value y = 27 when x = 6. You can find it by substituting into the equation.

y = 7(6) -15

y = 42 - 15

y = 27

The value of the relation in the table when x = 6 is y = 14. The equation has the greater value.

Part C: To find when y = 6, set it equal to 6 and solve for x.

6 = 7x - 15

21 = 7x

3 = x

The sigh of the product of two integers with the same sign is positive. What is the sigh of the product of three integers with t

tatyana61 [14]

Answer:

There are two possibilities

a) If the integers are positives the product will be positive.

b) If the integers are negatives the product will be negative.

Step-by-step explanation:

We need to use rule of signs to explain the answers

for answer "a"

We have (+)(+)( + ) equals positive

for answer "b"

We have (-)(-) = + then this multiply by the last integer which has negative sign

(+)(-) = -
