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!
Answer:
The oldest brother is 20 years old. PLEASE GIVE BRAINLIEST!!!
Step-by-step explanation:
Youngest = 5x - (x+4) = 60 Oldest = 5x - 60
5x - 1(x+4) = 60 5(16) - 60 =
5x - x - 4 = 60 80 - 60 = 20
4x - 4 = 60
4x = 60 + 4
4x = 64
x = 64 ÷ 4 x = 16
Youngest = 16
Middle = 18
Oldest = 20
Answer:
a) 50.24 ft²
b) 150.72 ft²
Step-by-step explanation:
Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet.
The distance across a circle is also called a diameter, Hence,
D = Diameter = 8 ft
The Area of a circle = πr²
r = Diameter/2 = 8ft/2 = 4ft
π = 3.14
Hence,
The Area of the circle = π × (4 ft)²
= 50.24 ft²
a) Approximately the amount of wall the circle will cover is 50.24 ft².
b) How much area will he cover if he painted a circle on three walls?
This is calculated as:
1 wall = 50.24 ft²
3 walls = x
Cross Multiply
x = 3 × 50.24 ft²
x = 150.72 ft²
Answer:
99.266
Step-by-step explanation:
11x6=66
7^2-6^2=13
sqrt13=3.6055
3.6055x6=21.633
21.633x2=43.266
43.266+66=99.266
Answer:
(-5)f(x)= -10x^2.
Step-by-step explanation:
If f(x) = 2x^2
We need to find (-5)f(x) = (-5) (2x^2) = -10(x^2) = -10x^2.
To solve this problem you just need to multiply (-5) by "2" which is the factor that multiplies the term "x^2"
