4.18/0.68=6.147058824 this is the answer of your questions
Parallel, therefore gradient is the same = 2
y-y1=m(x-x1)
y+2=2(x-3)
y+2=2x-6
y=2x-8
Option A
Answer:
(0.75) to the 3rd power is 0.421875
then multiply that by 240 and you get 101.25
rounded to the nearest 10th would be 101.3
Step-by-step explanation:
Answer:
center (6, -5) radius 3
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center of the circle and r is the radius.
(x − 6)² + (y + 5)² = 9
The center is (6, -5) and the radius is 3.
Answer:
60 square units
Step-by-step explanation:
We can use Pythagoras to solve this as appropriately projecting lines from any point will form a triangle. The vertical and horizontal lengths of which can be read of from the axis.
