Answer:
the first one should be 5.28x10^-2 and the second one should be 3.2x10^6
Step-by-step explanation:
because with 0.0528 you move the decimal right twice. which makes it negative.
with 3,200,000 you assume that the decimal is at the end and move it between the three and the two. making it have 6 moves. since it moves left its positive
Answer:
C and E
Step-by-step explanation:
We are given that
A.
Hence, it is not in proportional relationship with (0.2,0.3)
B.(2.7,4.3)
Hence, it is not in proportional relationship with (0.2,0.3).
C.(3.2,4.8)
Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).
D.(3.5,5.3)
Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).
E.(5.2,7.8)
Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).
4n² - 15n + 14<span> is always the product of two numbers, for it to be prime number, one of these factors must be either 1 or -1.
Case n - 2 = 1
That would be n = 3
Then </span>4n² - 15n + 14<span> = 5 , which is prime.
Case n - 2 = -1
That would be n = 1
Then </span>4n<span>² - 15n + 14 = 3, which is also prime.
Case 4n - 7 = 1
That would be n = 2 and that makes other factor (n-2) zero so it's not prime
Case 4n-7 = -1
That would be n = 3/2 which is not integer, so </span>4n<span>² - 15n + 14 will not be interger.
For any other n values, </span>4n<span>² - 15n + 14 will be composite number since it is product of two factors.
Therefore we are left with n = 1 and n = 3; only two values of n.</span>
Answer:
Step-by-step explanation:
Rational Numbers are defined as set of numbers that can be written as a/b.
where,
a and b are integers, but b is not equal to 0; an integer or a fraction.
Also, a rational number is a number that is expressed as the quotient or fraction a/b of two integers, where a numerator a and a non-zero denominator b is found. Since a may be equal to 1, every integer is a rational number.
