X = 7
Rearrange -> 2•X+5- (19) = 0
Pull out the like terms -> 2x -14 = 2 • (X - 7)
Solve -> 2 = 0
X- 7 = 0
So, that means "X" -> 7
Answer:
V = 34,13*π cubic units
Step-by-step explanation: See Annex
We find the common points of the two curves, solving the system of equations:
y² = 2*x x = 2*y ⇒ y = x/2
(x/2)² = 2*x
x²/4 = 2*x
x = 2*4 x = 8 and y = 8/2 y = 4
Then point P ( 8 ; 4 )
The other point Q is Q ( 0; 0)
From these two points, we get the integration limits for dy ( 0 , 4 )are the integration limits.
Now with the help of geogebra we have: In the annex segment ABCD is dy then
V = π *∫₀⁴ (R² - r² ) *dy = π *∫₀⁴ (2*y)² - (y²/2)² dy = π * ∫₀⁴ [(4y²) - y⁴/4 ] dy
V = π * [(4/3)y³ - (1/20)y⁵] |₀⁴
V = π * [ (4/3)*4³ - 0 - 1/20)*1024 + 0 )
V = π * [256/3 - 51,20]
V = 34,13*π cubic units
The frequency in a study like this means the number of people which chose that option. Since the patients must chose one of them, then the sum of all the frequencies must be equal to the number of patients that answered the research. With this in mind we can find the missing value, x.
There were 36 patients that reported no pain.
Answer:
11 = 16
Step-by-step explanation:
Area = length x width
A = L•W
There are 3 feet in one yard.
6 yards = 18 feet
4 yards = 12 feet
A = (18)(12)
A = 216 square feet
