Mathematics
1 answer:
Vlad [161]2 years ago
8 0

Answer:

y= 1/4,1/2,1,2,4,8,16,32,64

Step-by-step explanation:

Make negative powers positive by turning them into a fraction so 2^{-2} is really

\frac{1}{2^{2} } = \frac{1}{4} so 2^{-1} is just \frac{1}{2}. then 2^{0} =1 [any number to the zero power is = 1],

2^1 = 2, 2^2=4, 2^3=8, 2^4=16, 2^5=32, 2^6 = 2x2x2x2x2x2=64

What is more 7 7/9 or 7 4/5?
bezimeni [28]

First, turn the mixed numbers into improper fractions.

7 7/9 = 70/9

7 4/5 = 39/5

Second, find common denominators.

70/9 = 350/45

39/5 = 351/45

351/45 > 350/45

Therefore, 7 4/5 is greater.

Best of Luck!

The diffrence between an integer p and (-5) is 1 find the value of p ​
Nastasia [14]

Solution:

<u>Note that:</u>

  • Given sentence: The difference between an integer p and (-5) is 1.

<u>Let's reread the sentence carefully.</u>

The difference between an integer p and (-5) is 1.

  • => p - (-5) = 1

<u>Change the sign.</u>

  • p - (-5) = 1
  • => p + 5 = 1

<u>Subtract 5 both sides:</u>

  • p + 5 = 1
  • => p + 5 - 5 = 1 - 5
  • => p = -4

Can you identify these numbers as rational or irrational. Please explain.<br><br> -√127 and 291.87
irina [24]
An irrational number/value is one you cannot express in terms of a ration, or a fraction, it cannot be written as fraction

now 291.87... is simple, two decimals, so you use two zeros at the botom and end up with \bf \cfrac{29187}{100} and boom, there you are, a fraction, nice and dandy

now, let's see the first one -√(127)  well, low and behold, 127 is a prime number, and and thus is has no two factors that'd serve as root, so, there's no rational root that'd give that, that makes it irrational

Round 5049 correct to 1 significant figure​
Step2247 [10]

5000

  • Addition (+) and subtraction (-) round by the least number of decimals.
  • Multiplication (* or ×) and division (/ or ÷) round by the least number of significant figures.
  • Logarithm (log, ln) uses the input's number of significant figures as the result's number of decimals.
  • Antilogarithm (n^x.y) uses the power's number of decimals (mantissa) as the result's number of significant figures.
  • Exponentiation (n^x) only rounds by the significant figures in the base.
  • To count trailing zeros, add a decimal point at the end (e.g. 1000.) or use scientific notation (e.g. 1.000 × 10^3 or 1.000e3).
  • Zeros have all their digits counted as significant (e.g. 0 = 1, 0.00 = 3).
  • Rounds when required, after parentheses, and on the final step.
