Answer:
3y= -2x-6
Step-by-step explanation:
The two points on the line are (-3,0) and (0,-2)
so you first get the gradient;
gradient= <u>change in y</u>
change in x
= <u>-2-0</u>
0-(-3)
=<u> -2</u>
3
so the answer above is the gradient
then pick one point that you used to get the gradient with, so as for me I'll pick (-3,0) and then a general point which is always (x, y)
since you have the gradient you can easily get the equation by doing this
<u>y-0</u><u>. </u><u> </u> = <u>-2</u>
x-(-3). 3
then crossmultiply to get the equation of the line
3y= -2(x+3)
3y= -2x-6
Answer:
angle of 90 degrees
Step-by-step explanation:
if the length satisfy the pythagorean theorem (a2+b2=c2) then it is a right traingle
An easy way to do this is to do trial and error.
All possible places to put the bracket:
a) (25 - 8) - 2 = 19 But since BEDMAS goes from left to right with Addition and Subtraction, the equation is unaffected.
b) 25 - (8 - 2) = 19
25 - 6 = 19
Therefore b) is correct.
Basically, all you have to do is count how many 6 's you have and then write 6^4. Which is 6 to the fourth power.
Answer:
The volume is changing at a rate given by:
Step-by-step explanation:
Let's recall the formula for the volume of acone, since it is the rate of the cone changing what we need to answer:
Volume of cone = 
where B is the area of the base (a circle of radius R) which equals = 
and where H stands for the cone's height.
We apply the derivative over time operator (
) on both sides of the volume equation, making sure that we apply the rule for the derivative of a product:
