Answer:
7
Step-by-step explanation:
7.base of triangle=√(32.5²-28²)
=√4.5(32.5+28)
=√4.5(60.5)
=√272.25
=16.5
area of triangle=1/2 ×16.5×28
=231
volume=231×31=7161 km³
8.
39.4-25=14.4
width=√(30.6²-14.4²)
=√16.2(30.6+14.4)
=√16.2(45)
=√729
=27
volume=(25+39.4)/2 ×27×35
=(64.4)/2×27×35
=32.2×27×35
=30429 cm³
Answer:
A) Function 2 shows a greater rate of change because Jenny spends $6 each month and Sandra spends $5 each month.
Step-by-step explanation:
The y-intercept for Sandra is 55 and the slope is -5. While Jenny's y-intercept is 50 and slope is -6.
6 is a greater number therefore causing Jenny's slope to decrease faster causing her to have less money at a much faster rate. (rate of change=slope) Jeny's slope is decreasing at a faster rate of change because she is spending more money everyday than Sandra is.
Hope this helps! Have a great day! :)

Answer:
85t
Step-by-step explanation:
1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

-z³ + 5k^6 + z³ -10k^6
(-z³ cancels out with z³)
5k^6 -10k^6
(then subtract)
Answer is -5k^6
21+4(32-5)=448
I think it’s 448
