27 : (-3 + (-7)) = 27 : (-10) = -2.7
Answer:
7/10
51/100
473/1000
27/100
537/1000
1649/10000
Step-by-step explanation:
im curious about what the dots are in .16.49 and .5.37, why are there two dots?
h(-2) just means that you should substitute x for -2 in the function.
h(-2) = 2(-2)^2
h(-2) = 8
Therefore, h(-2) + 5 = 8 + 5
h(-2) + 5 = 13
GM = 1/2(GH)
7x + 2 = 1/2(32)
...multiply 1/2
7x + 2 = 16
...subtract 2
7x = 14
...divide 7
x = 2
GM = 7(2) + 2 = 16
MH = GM, so it is also 16
Answer:
only q or r can be irrational
Step-by-step explanation:
Rational numbers are numbers that can be expressed in the form a/b, where both a and b are integers and b ≠ 0. The decimal representation of an rational numbers either repeats the sequence of digits over again or terminates at a finite number.
Irrational numbers are numbers that are not rational. The decimal representation of an irrational number does not repeat a sequence of digits over again and never terminates. e.g √2, π.
The product of two irrational numbers is a rational number, the product of two rational numbers is a rational number while the product of a rational and irrational number is an irrational number. Hence since in p*q*r is an irrational number and p is a rational number, If both q and r are irrational then:
q*r = irrational * irrational = rational
p*(q*r) = rational * rational = rational. Since the result is not an irrational number then both q and r cannot be irrational.
But, If either q and r are irrational then:
q*r = irrational * rational = rational * irrational = irrational
p*(q*r) = rational * irrational = irrational. Since the result is an irrational number then only q or r can be irrational
