This is true. All numbers that end in zero or five are divisible by 5, and a number that ends in zero is even, and all even numbers are divisible by two.

Well he's correct except that what if the number is zero? Zero has no other factors (technically speaking, anyway). But aside from zero, he's completely right.
Hope this helps!

\dfrac{1}{4}+\dfrac{1}{4}+x-\dfrac{3}{4}=\left(\dfrac{1}{4}+\dfrac{1}{4}-\dfrac{3}{4}\right)+x=\dfrac{1+1-3}{4}+x=\dfrac{-1}{4}+x=x-\dfrac{1}{4}

F=((-1,1),(1,-2),(3,-4)) g=((5,0),(-3,4),(1,1),(-4,1)) find (f/g)(1)
Helen [10]

9514 1404 393

Answer:

  -2

Step-by-step explanation:

(f/g)(1) = f(1)/g(1) = -2/1 = -2

__

The value of f(1) is the second number in the ordered pair (1, -2) that is part of the definition of function f. Similarly, for g, we look for the ordered pair that has 1 as its first value. The second value is g(1).

What is the length of AB? (Nearest TENTH) A.34 B.105.3 C.11.8 D.24.7
jasenka [17]

Answer:

The answer is option A.

Step-by-step explanation:

To find the length of AB we use sine

sin∅ = opposite / hypotenuse

From the question

AB is the hypotenuse

AC is the opposite

sin 36 = AC / AB

sin 36 = 20/ AB

AB = 20 / sin 36

AB = 34.026

<h3>AB is 34 to the nearest tenth</h3>

Hope this helps you
