Answer:115.4685yd^3
Step-by-step explanation:
Volume of cone=1/3πr2h
V=1/3×3.142×3.5yd×3.5yd×9yd
V=115.4685yd^3
The correct answer is: [A]: " 2x³ + 7x² + 12x − 8 " .
______________________________________________________
Explanation:
__________________________________________
Given:
__________________________________________
" (x² + 4x + 8) (2x − 1) " ; Find the product:
↔ " (2x − 1) (x² + 4x + 8) " ;
__________________________________________
Note: " (a + b) (c + d + e) = ab + ad + ae + bc + bd + ae " .
__________________________________________
→ " (2x − 1) (x² + 4x + 8) =
(2x * x²) + (2x * 4x) + (2x *8) + (-1 * x²) + (-1 * 4x) + (-1 * 8) ;
= 2x³ + 8x² + 16x + (-1x²) + (-4x) + (-8) ;
= 2x³ + 8x² + 16x − x² − 4x − 8) ;
→ Combine the "like terms" :
+ 8x² − x² = + 7x² ;
+ 16x − 4x = + 12x ;
_______________________________________________________
And rewrite the expression:
_______________________________________________________
→ " 2x³ + 7x² + 12x − 8 " ;
→ which is: Answer choice: [A]: " 2x³ + 7x² + 12x − 8 " .

Answer:
16.2 = 
and 121 = 
Step-by-step explanation:
16.2 can be simplified to its fraction form, which is
which is 16.2
121 is already simplified since it is a whole number, but its fraction form would be
which is 121

We should each take these probabilities first individually.
Probability of tails in a coin toss = 1/2
Probability of <span>drawing letter T from the alphabet = 1/26
Probability of 2 tails in 2 coin toss = 1/4
Sample space = {HH, TT, HT, TH}
Add these together since these events happen after another = 1/2 + 1/26 / + 1/4 = 41/52
The final probability is 41/52</span>
