The answer is 3333.
The digits of F are all the same. ✔ They all have same digit 3
The sum of all the digits of F is 12✔ 3+3+3+3=12
When any two of the digits are multiplied together, the answer is 9.✔ 3*3= 9
F is a four-digit number.✔ 3 3 3 3
1 2 3 4
Answer:
318.267 feet per second
19096 feet per minute
Step-by-step explanation:
1) 217*5280 to get feet
2) 1145760/60 to get feet per minute
3) 19096/60 to get feet per second
To figure out the solution in a problem related to calculate maximum or minimum of something, you've to derive the involved equation, and make it equal to 0, solving the x.
So:
y = -0'296x² + 2'7x
y' = -0'592x + 2'7
0 = <span>-0'592x + 2'7
</span><span>-0'592x = 2'7
</span>x = 4'56
And if we substitute 4'56 on the first equation:
y = -0'296·<span>4'56² + 2'7·4'56
y = 6'16
So the length of the jump is 4'56cm, and the height 6'16cm.</span>

Step-by-step explanation:
Answer:
68.20°
Step-by-step explanation:
Using Pythagoras rule :
Tanθ = opposite / adjacent
Adjacent = 8ft
Opposite = 20
Tanθ = 20 / 8
θ = tan^-1(20/8)
= 68.198590
Hence, angle of elevation = 68.2°
