Answer:
6 cm and 8 cm
Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
10² = x² + (x+2)²
100 = x² + x² + 4x + 4
0 = 2x² + 4x − 96
0 = x² + 2x − 48
0 = (x − 6) (x + 8)
x = 6 or -8
x must be positive, so x = 6. Which means x+2 = 8.
Answer:
Step-by-step explanation:
We are given that a function
We have to find the derivative of the function
By using
Differentiate w.r.t x
By using formula
Hence,the derivative of function
Group like terms and factor
group the ones with 8 together and the rest apart
(x²+xy)+(-8x-8y)
factor
x(x+y)+(-8)(x+y)
factor out (x+y)
(x+y)(x-8)
Answer:
The value of n
n = 0.86
n = -0.73
Step-by-step explanation:
Given:
The given equation is
We need to find the value of n when d = -2n.
Solution:
Rewrite the given equation as
Substitute d = -2n in above equation.
Now, we first find the root of the above equation.
Use quadratic formula with .
Put a, b and c value in above equation.
For positive sign
n = 0.86
For negative sign
n = -0.73
Therefore the value of n = 0.86 or n = -0.73
