Answer: B
Step-by-step explanation:
The question is asking for you to use the Pythagorean Theorem in order to find the length or line AB.
a^2+b^2=c^2
Since AB is what we are trying to find in this situation it is c. The graphic shown tells us that the length of line CA= (y2-y1) and CB= (x2-x1), these numbers represent a and b in the expression shown above. From here you should implement the information into the equation.
(x^2-x^1)^2+(y2-y1)^2= AB
The next step in finding the product would be to square both sides of the equation. In this case we only need to square the side with the calculation because the variable AB already represents the answer you would calculate. Which leaves us with the answer shown in the image below.
So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.
So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.
f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10
Its easy to convert 86 kilometers per hour to meters per second :
Just divide the speed which is 86 by 3.6
86 divide 3.6 = 24 m/s or meter per second
500 or 600 depending on the maths question
Answer:
A = 3
B = -5
C = 2
Step-by-step explanation:
The way to format a quadratic equation is: 
, so the first step to solving this is to format it in the right way, where the 
comes first, the 
second, and the number alone.
After formatting, your equation should look like this: 
From here, you can see the the <em>a </em> is 3, the <em>b</em> is -5, and the <em>c </em>is 2
