3=21/(x+5)
Cross multiply
3(x+5)=21
Divide 3
X+5 = 7
Subtract 5
X= 2
Answer:
Step-by-step explanation:
Given
Required
Determine the length of the congruent sides
Since, the triangle is an isosceles triangle, the perimeter would be calculated using
Where P represents Perimeter and B represents Base
So:
Solve for 2L
Divide through by 2
<em>Hence; The length (L) of the congruent sides is </em><em></em>
The value of the square root function after differentiation is .
The given equation is :
x³√4y = 5
Now we will use implicit differentiation
In mathematics, the derivative of a simple function that resembles a real variable measures how sensitive the function's value (or output value) is to changes in the underlying assumption (input value). The derivative is the fundamental tool in calculus.
The value of y from the equation is :
y = 25/4 x⁻³
now if we differentiate this function we get the same result.
y'=3/x
Hence we can see that the value of both the solution are equal.
A measure of how quickly an object's position changes over time is its velocity, which is the derivative of that object's point with regard to time.
Hence the required solution of the differentiation is
