Answer:
f(4) = -1
Step-by-step explanation:
f(4) = 3(4)^2 - 10(4) -9
= 3*16 - 40 - 9
= 48 - 40 - 9
= -1
Answer:
Volume of the prop = 706.5 in³
Step-by-step explanation:
Volume of the prop given in the picture = Volume of hemisphere + Volume of the cone
Volume of the hemisphere =
where 'r' = radius of the hemisphere
For r = 5 in,
Volume of the hemisphere =
= 261.67 in³
Volume of a cone =
Here r = radius of the circular base
h = height of the cone
For 'r' = 5 in and h 17 in.
Volume of the cone =
= 444.83 in³
Volume of the prop = 261.67 + 444.83
= 706.5 in³
Answer:
14 ; 40
Step-by-step explanation:
Number of unpopped popcorn = 1600 kernels
Kernel per popped corn = 120
Number of boxes needed :
Number of unpopped / kernel per popped corn
1600 / 120
= 13.3333
Hence, number of boxes needed = 14
Number of popped kernel. In partially filled box :
1600 - (120 * 13)
1600 - 1560
= 40
Ok so when a parenthesee or this symbol ( is beside a letter/Number, in this case 5 you multiply it by whats inside, so 5x10.5, and 5x10.5=52.5. Now for S, it would be 52.5+S.
That is your answwer, and if you wouldn't mind, could I have brainliest?
