Equation 2 starts off at 4m=4+4n not -4. so trace steps back to step 1 and look at the numbers again

Answer:

Step-by-step explanation:

you have right triangle & isosceles

so is 45-90-45

PR^2=PQ^2+QR^2

c^2=a^2+b^2, where c is the hypotenuse, and a=b

(3 $\sqrt{2}$ )^2=2a^2

18=2a^2

9=a^2

a=3, b=3, both legs are equal to 3

How many positive whole numbers less than 100 are divisible by 3, but not by 2?

denis23 [38]

Answer:

Step-by-step explanation:

The easiest way to do this is either to find a pattern or list them. We'll list them first.

3 9 15 21 27 33 39 45 51 57 63 69 75 81 87 93 99

17 but there is a pattern

Starting with 3, add 6 to every number you find in the series. There is a formula that covers this

l = a + (n- 1)*d

a = 3

l = 99

d = 6

99 = 3 + (n - 1)*6 Subtract 3

99 - 3 = (n - 1)*6

96 = (n - 1)*6 Divide by 6

96/6 = (n -1)*6/6

16 = n - 1 Add 1 to both sides.

16+1 = n - 1 + 1 Combine

17 = n

Find the domain and range of these functions. a) the function that assigns to each pair of positive inte- gers the maximum of th

IRISSAK [1]

Answer:

See below

Step-by-step explanation:

Domain: the cartesian product of integers ZxZ

Range: the integers Z, for every p in Z is the image of (p, p-1)

Domain: the positive integers Z+

Range: the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} obviously, f(1)=9, f(12)=8, f(123)=7,...,f(123456789)=1 and f(1234567890)=0. So, every number in {0,1,...,9} is the image of some positive integer.

Domain: all the bit strings. Since any real number can be written as a bit string in the binary system, the domain is actually the set R of real numbers.

Range: a bit string can have 0 or 1 or 2 or more blocks “11”, so the range is the set N of natural numbers including 0.

Domain: all the bit strings (the real numbers as in c).

Range: the natural numbers N plus 0

Three consecutive even integers have a sum of 18. Find the integers.

My name is Ann [436]

Let
x = first consecutive even
x + 2 = second consecutive even
x + 4 = third consecutive even

Based on the problem, we equate
x + (x + 2) + (x + 4) = 18
Solving for x,
3x + 6 = 18
3x = 18 - 6
3x = 12
x = 12/3
x = 4
and x + 2 = 4 + 2 = 6
and x + 4 = 4 + 4 = 8

Therefore, the three consecutive even integers are 4, 6, 8.
