Answer: 480 pennies
Explanation: 4/5=8/10 8/10-3/10= 5/10
240 pennies filled half of the bank thus 480
D. All numbers greater than -10 and less than or equal to 8
Answer: -2
Let’s try x = -12
1/2(-12) - 5 = -6
PEMDAS says to multiply first
1/2 x -12 = -6
So
-6 - 5 = -6
-6 - 5 = -11 not -6 so it’s not that
Now let’s do x = -2
1/2(-2) - 5 = -6
Again, you multiply first
1/2 x -2 = -1
-1 - 5 = -6 so it works
Answer:
(a) 7.5 seconds
(b) The horizontal distance the package travel during its descent is 1737.8 ft
Step-by-step explanation:
(a) The given function for the height of the object is s = -16·t² + v₀·t + s₀
The initial height of the object s₀ = 900 feet
The initial vertical velocity of the object v₀
= 0 m/s
The time it takes the package to strike the ground is found as follows;
0 = -16·t² + 0×t + 900
900 = 16·t²
t² = 900/16 = 62.25
t = √62.25 = 7.5 seconds
(b) Given that the horizontal velocity of the package is given as 158 miles/hour, we have
158 miles/hour = 231.7126 ft/s
The horizontal distance the package covers in the 7.5 second of vertical flight = 231.7126 ft/s × 7.5 s = 1737.8445 feet = 1737.8 ft to one decimal place
The horizontal distance the package travel during its descent = 1737.8 ft.
