Calculus<br> The following curve passes through (3,1)<br> Using linear lineralization
Novay_Z [31]

Answer:

Option 1.1

Step-by-step explanation:

The linearization of a curve implies the use of calculus to find the local value for the derivative and approximating the function by the use of the formula

F(x) \approx F(x_0) + F'(x_0)(x-x_0)

The function is given in such way that it's much easier to find the derivative by implicit differentiation than isolating any of the variables

2x^2y+y=2x+13

Differentiating with respect to x, we have

4xy+2x^2y'+y'=2

Computing y' in the given point (3,1) we have

4(3)(1)+2(9)y'+y'=2

y'=\frac{2-12}{19}

y'=-\frac{10}{19}

The function will be approximated with the expression

F(x) = 1 -\frac{10}{19}(x-3)

To find the approximate value for x=2.8

F(2.8) = 1-\frac{10}{19}(-0.2)=1.1

The correct value is the option 1.1

BRAINLIESTTT ASAP! PLEASE HELP ME :)
kherson [118]

Answer:

b. \displaystyle 225y^2 + 150xy + 100x^2 = 225y^2 + 150xy + 100x^2

a. \displaystyle [8x + 12y]^2 + [6x + 9y]^2 = [10x + 15y]^2

Step-by-step explanation:

b. \displaystyle 225y^2 + 150xy + 100x^2 = 225y^2 + 150xy + 100x^2

a. \displaystyle [8x + 12y]^2 + [6x + 9y]^2 = [10x + 15y]^2

The two expressions are identical on each side of the equivalence symbol, therefore they are an identity.

I am joyous to assist you anytime.

Find tan(450-a), If <br><img src="https://tex.z-dn.net/?f=%20%5Ctan%28a%29%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20" id="TexFormula1"
Inessa05 [86]

Answer:

tan(450-a)=5\sqrt{3}-8

Step-by-step explanation:

We know that:

tan(a-b)=\frac{tan(a)-tan(b)}{1+tan(a)tan(b)}

tan(450-a)=\frac{tan(450)-tan(a)}{1+tan(450)tan(a)}

Remember:

450°=360°+60°

and:

tan(a)=\frac{1}{2}

Thus:

tan(450-a)=\frac{tan(60)-tan(a)}{1+tan(60)tan(a)}\\\\

Then:

tan(450-a)=5\sqrt{3}-8
