3/8 x 8 = 3
Answer:
Part 1)
Part 2)
Step-by-step explanation:
The correct question in the attached figure
Part 1)
we have the formula
where
e the eccentricity
a is the length of the semi-major axis
b is the length of the major axis
solve for a
That means
Isolate the variable a
squared both sides
subtract 1 both sides
Multiply both sides by a^2
Divide both sides by (e^2-1)
Rewrite
square root both sides
simplify
Part 2) we have
Solve for a
substitute in the formula of part 1)
Gradient:
Find two points on the line and with those two points, calculate the difference in height(y coordinates) divided by the difference in width(x coordinates). If you get a positive value, then your line will be uphill.
Y-intercept:
Use y=mx+b
Find the slope first using the slope formula which is y2-y1 OVER x2-x1. Once you have that, take a point from the line and substitute the x and y coordinates along with the slope into y=mx+b.
So if your slope was 2/1 and your point was (4,8), it would be:
8=2(4)+b
8=6+b
*subtract 6 from both sides*
b=2
