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
H-8=2. The only solution to that equation is H=10. Any other number isn't.
Step-by-step explanation:
Given the formula
a(n+1)=an−3
The first term a(1) = 31
<u>For</u><u> </u><u>the</u><u> </u><u>second</u><u> </u><u>ter</u><u>m</u>
a(2)
We have
a( 1 + 1) = a(1) - 3
a(2) = 31 - 3
a(2) = 28
<u>For</u><u> </u><u>the</u><u> </u><u>thir</u><u>d</u><u> term</u>
a(3)
We have
a(2+1) = a(2) - 3
a(3) = 28 - 3
a(3) = 25
<u>For</u><u> </u><u>the</u><u> </u><u>four</u><u>th</u><u> term</u>
a(4)
That's
a(3+1) = a(3) - 3
a(4) = 25 - 3
a(4) = 22
Hope this helps you
Answer:
<u>4,712 yards.</u>
We can use the formula V=1/3hπr² to figure out what the volume of the cone is.
So using the numbers provided the new equation would be V=1/3(20)π15², which would come out to 4,712 yards.
