Step-by-step explanation:
Answer:
(x, y, z) = (4, -1, 3)
Step-by-step explanation:
To solve the system of equations:
2x − 3y + 4z = 23 .........................(1)
x + 2y − 4z = −10 ..........................(2)
3x − y + 2z = 19..............................(3)
Simultaneously, we do that by first eliminating one variable from any two equations to have an equation in two variables. The process is repeated with one of the used equations and the third unused equation to have a second equation in two variables. The two equations in two variables obtained can then be easily solved simultaneously.
Let us eliminate z from (1) and (2)
Add (1) and (2)
(1) + (2):
3x - y = 13 ........................................(4)
Multiply (3) by 2
(3) × 2
6x - 2y + 4z = 38 ............................(5)
Add (5) and (2)
(5) + (2):
7x + 0 + 0 = 28
x = 28/7 = 4
Putting this in (4)
3(4) - y = 13
y = 12 - 13 = -1
Putting this in (3)
3(4) - 4(-1) + z = 19
z = 19 - 16 = 3
Therefore,
(x, y, z) = (4. -1, 3)
Answer:
19.61505096...
Step-by-step explanation:
Area in a circle is pi(ratio)squared
Circumference is pi multiplied by diameter
Ratio is half of diameter
15.7 divided by pi is roughly 5 (4.997465213 to be exact)
Half of 5 is 2.5
pi(2.5)squared is 19.61505096...
Answer:
h = 2.25 m
Step-by-step explanation:
<u><em>Given:</em></u>
Speed = v = 12 ft/sec
Acceleration due to gravity = g = 32 ft/sec²
<u><em>Required:</em></u>
Height = h = ?
<u><em>Formula:</em></u>
v = 
<u><em>Solution:</em></u>
For h, the formula will be:
=> h = 
=> h = 
=> h = 
=> h = 2.25 m
