Answer:
Step-by-step explanation:
1. 11x = 44
x = 4
2. 3w = -9
w = -3
3. -4n = -16
n = 4
4. 6h = 36
h= 6
Answer:
C) 7
===========================================
Work Shown:
Use the slope formula
m = (y2-y1)/(x2-x1)
Plug in the given slope we want m = -5/3 and also the coordinates of the points. Then isolate r
m = (y2-y1)/(x2-x1)
-5/3 = (2-r)/(r-4)
-5(r-4) = 3(2-r) .... cross multiplying
-5r+20 = 6-3r
-5r+20+5r = 6-3r+5r .... adding 5 to both sides
20 = 6+2r
20-6 = 6+2r-6 ....subtracting 6 from both sides
14 = 2r
2r = 14
2r/2 = 14/2 .... dividing both sides by 2
r = 7
The slope of the line through (4,7) and (7,2) should be -5/3, let's check that
m = (y2-y1)/(x2-x1)
m = (2-7)/(7-4)
m = -5/3
The answer is confirmed
now, notice, the volume of the cylinder is really about the same as the volume of a cone, just 3 times larger, assuming "h"eight and "r"adius for both is the same amount.
now, if we know the cone with that "h" and "r" has a volume of 6π, the cylinder is.... well, you already know.
Answer:
10.4325
Step-by-step explanation:
For 1 year: (0.65) + (0.65)(0.07) = 0.6955
For 15 years: 0.6955 X 15 = 10.4325
All together: (0.65+(0.65*0.07))*15 = 10.4325
