If A = (7,9) and B = (3 , 12) what is the length of AB

Mathematics
1 answer:
V125BC [204]2 years ago
7 0

Answer:

AB = 5 units

Step-by-step explanation:

Calculate the length using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+ (y_{2}-y_{1})^2

with (x₁, y₁ ) = A(7, 9) and (x₂, y₂ ) = B(3, 12)

AB = \sqrt{(3-7)^2+(12-9)^2}

      = \sqrt{(-4)^2+3^2}

      = \sqrt{16+9}

      = \sqrt{25}

       = 5

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is
gavmur [86]

If

\nabla f=(ye^x+\sin y)\,\vec\imath+(e^x+x\cos y)\,\vec\jmath

then

\dfrac{\partial f}{\partial x}=ye^x+\sin y\implies f(x,y)=ye^x+x\sin y+g(y)

Differentiating with respec to y gives

\dfrac{\partial f}{\partial y}=e^x+x\cos y=e^x+x\cos y+g'(y)

\implies g'(y)=0\implies g(y)=C

So F is indeed conservative, and

f(x,y)=ye^x+x\sin y+C

Answer:

Option A

Step-by-step explanation:

Given:

Center of circle = (h,k)= (3,8)

Radius = r = 5

The standard form of equation of circle with center and radius is:

(x-h)^2+(y-k)^2=r^2\\Putting\ the\ values\\(x-3)^2+(y-8)^2=(5)^2\\Simplifying\\x^2+9-6x+y^2+64-16y=25\\x^2+y^2-6x-16y+9+64=25\\x^2+y^2-6x-16y+73=25\\x^2+y^2-6x-16y+73-25=0\\x^2+y^2-6x-16y+48=0

Therefore, the general form of the equation of circle given is:

x^2+y^2-6x-16y+48=0

Hence, option A is correct ..
