To find this you will use the y2-y1/x2-x1
(-7/2, -3) (-5, 5/2)
x1 y1 x2 y2
5/2 - (-7/2)
_________
-5-(-3)
12/2=6
-2
6/-2= -3
slope= -3
Answer:
Step-by-step explanation:
let x be part at 8%, y be part at 10% and z be part at 15%
(1) x+y+z=6300
the amount of money invested at 15% was $100 more than the amounts invested at 8% and 10% combined. so
(2) z=x+y+100
The total annual income from these investments was $766. so
0.08x+0.1y+0.15z=766 or
(3) 8x+10y+15z=76600
substitute (2) into (1)
x+y+x+y+100=6300
(4) 2x+2y=6200
substitute (2) inot (3)
8x+10y+15(x+y+100)=76600
(5) 23x+25y=75100
solving (4) n (5)
x=1200
y=1900
z=1200+1900+100=3200

Slope = 3.000/2.000 = 1.500
x-intercept = 11/-3 = -3.66667<span>
y-intercept = 11/2 = 5.50000

Radius of ball is 6 inches. Then the volume is 904.32
<u>Solution:</u>
Given that, radius of a ball is 6 inches.
We have to find the volume of the ball with 6 inches radius.
Now, we know that, a ball will be in a shape of sphere, so we have to use the volume of a sphere formula to find the volume of the ball.
<em><u>The volume of sphere is given as:</u></em>
where r is the radius.
Here in our problem, r = 6
Hence the volume is 904.32
