Since 4 = $3.88
Then 1 = 3.88/4
= $ 0.97
Answer:
The volume of the sphere is 1436 in³
The equation is
V = ⁴⁄₃ * 3.14 * (7ft)³
Step-by-step explanation:
radius = half of diameter
d = 14ft
r = 14ft / 2 = 7ft
To calculate the volume of a sphere we have to use the following formula:
V = volume
r = radius = 7ft
π = 3.14
V = ⁴⁄₃πr³
we replace with the known values
V = ⁴⁄₃ * 3.14 * (7ft)³
V = 4.187 * 343 in³
V = 1436 in³
The volume of the sphere is 1436 in³
Answer:
Step-by-step explanation:
depreciation for three years = 32000 - 24500 = $ 7500
depreciation per year = 7500/3 = $ 2500
depreciation % = (2500/32000)*100 = 7.81%
Value of truck after n years = 32000 * (7.81%)*n
1. find equation
general solutions are:
![y = a x^{2} +bx +c \\ \\ \frac{dy}{dx} = 2ax +b](https://tex.z-dn.net/?f=y%20%3D%20a%20x%5E%7B2%7D%20%2Bbx%20%2Bc%20%5C%5C%20%5C%5C%20%5Cfrac%7Bdy%7D%7Bdx%7D%20%3D%202ax%20%2Bb)
for P(0,-11)
![-11 = 0a + 0b +c](https://tex.z-dn.net/?f=-11%20%3D%200a%20%2B%200b%20%2Bc%20)
⇒
![c = -11](https://tex.z-dn.net/?f=c%20%3D%20-11)
for p(1,-13)
![-13 = 1a + 1b -11 \\ a+b = -2](https://tex.z-dn.net/?f=-13%20%3D%201a%20%2B%201b%20-11%20%5C%5C%20a%2Bb%20%3D%20-2)
and
![0 = 2a + b \\ b = -2a](https://tex.z-dn.net/?f=0%20%3D%202a%20%2B%20b%20%5C%5C%20b%20%3D%20-2a)
solve for a and b:
![a - 2a = -2 \\ a = 2 \\ b = -4](https://tex.z-dn.net/?f=a%20-%202a%20%3D%20-2%20%5C%5C%20a%20%3D%202%20%5C%5C%20b%20%3D%20-4)
the total equation is now:
![y = 2 x^{2} -4x -11](https://tex.z-dn.net/?f=y%20%3D%202%20x%5E%7B2%7D%20-4x%20-11)
To find the x-intercept set y=0 and solve for x
In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
