Since, it is given that 
Now, we have to identify the addition property for the given equation.
Associative property of addition states that for any real numbers say 'a' , 'b' and 'c', a+(b+c) = (a+b)+c
So, in the given question 28+29+42
We can use associative property as
(28+29)+42 = 28+(29+42)
57+42 = 28+71
99 = 99
Hence, among the given properties, associative addition property is used.
It’s easiest if you break it down in to sections. Times the two sides of the square/ rectangle together to get the area of each section. To find the area of the triangle, you do the same but just divide it by 2. Answer = 80
When the vertex is at the origin and the directrix is at y = -2.5, the the parabola must be facing upwards and have a general formula of y = 4a x^2. In this case, a is equal to 2.5 that is, y = 4*2.5 x^2 equal to y = 10 x^2
Answer:
4/3.
Step-by-step explanation:
sec^2 s = 1 + tan^2 s
= 1 + (3/4)^2
= 25/16
So sec s = √(25/16) = 4/3.
