To find when the ball reaches the ground, you would need to find the time that gives you a height value of zero.
Your answer would be 4 seconds
h = -16(4)^2 + 64(16)
h = -16(16) + 256
h = -256 + 256
h = 0
Hope this helps!
Common ratio means that you will be multiplying from the first number to get the second number.
To find the ratio we will work backwards, from right to left, and divide instead of multiply.
-43/-21.5 = 1/2
-86/-43= 1/2
-182/-86 = 1/2
r = 1/2
Answer:

Step-by-step explanation
Pie is infinite so there is no simple answer.
circumference divided by the diameter = pie
Answer:
Step-by-step explanation:
The formula for determining the the area of a sector is expressed as
Area of Sector = θ/360 × πr²
Where
θ represents the central angle.
π is a constant whose value is 3.14
r represents the radius of the circle.
From the information given,
The central angle is π/7 radian. Converting to degrees, it becomes
π/7 × 180/π = 180/7 = 25.714 degrees.
Area of sector = 77 square meters
Therefore
77 = 25.714/360 × 3.14 × r²
77 = 0.2243r²
r² = 77/0.2243 = 343.29
r = √343.29 = 18.53 meters
