Answer:
for the first one I think it is -5/-2 second is 1/-4 third one is 2/1 this may not be correct
Step-by-step explanation:
Answer: A= 460 mm2
Step-by-step explanation:
Hi, since the circumference formula is :
C = 2 π r
Where r is the radius, we can solve the formula for the radius replacing with the value given:
76 =2 π r
76 / (2 π) = r
r = 12.1 mm
Now , we have to apply the formula for the area of a circle.
A = π r^2
A = π (12.1)^2
A= 459.96 mm2= 460 mm2 (rounded to the nearest tenth, since .9 is higher than .5)
Feel free to ask for more if needed or if you did not understand something.
Linear functions are graphs with a straight line. With 1 independent and 1 dependent variable
<h2>
Hello!</h2>
The answer is:
<h2>Why?</h2>
If we want to find an equation of a line parallel to the given line, we must remember that parallel lines has the same slope.
So,
Line equation is:
Where:
So, we are given the function:
Where:
m=-5
Also, we are given the point where the line passes through (0,8), we can use it to find "b"
So, the equation will be:
To prove if we are right, let's substitute (0,8):
Have a nice day!
