Answer:
D = √(6 - 9)^2 + (3 + 2)^2]
Step-by-step explanation:
This is an application of the Pythagoras theorem:
D = √ [(x2 - x1)^2 + (y2 - y1)^2] where the 2 points are (x1, y1) and
(x2, y2).
So in this case we have
D = √[(6 - 9)^2 + (3 - -2)^2]
D = √(6 - 9)^2 + (3 + 2)^2]

Step-by-step explanation:
Answer:
i.e. The inverse function
i.e. The French size of a dress if it is U.S. size 10 is 42.
Step-by-step explanation:
Given
Solving (a): The inverse function
Replace d(x) with y
Swap y and x
Make y the subject
Replace y with d'(x)
Hence, the inverse function is:
Solving (b): US size of 10
Substitute
Answer:
[A] y(y + 4) - y = 6
[C] 4 b (b)=0
Step-by-step explanation:
First let know what is a quadratic functions(s):
A function is called Quadratic if it consist of only one variable, maximum of three terms, and highest degree of the variable in that Polynomial is 2.
Now let's go through the answer choices:
[A]
y *(y+4) - y =6
y² + 4 y - y -6=0
y²+3 y -6=0
Thus, This is Quadratic Function.
[B]
3 x +2 + 6 x -1=0
9 x-1=0
Thus, This is not Quadratic Function
[C]
4 b*(b)=0
4 b²=0
Thus, This is Quadratic Function.
[D]
3 a- 7 =2 * (7 a-3)
3 a - 7=14 a - 6
3 a - 14 a = 7 -6
-11 a =1
Thus, This is not a Quadratic Function.
Hence, [A] and [C] are quadratic functions.
