Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give

Aloiza [94]

Answer:

$y = 4e^2x - 3e^2$

Step-by-step explanation:

$f(x) = e^{2x^2}$

lets calculate the derivate of f using the chain rule:

$f'(x) = e^{2x^2}* (2x^2)' = e^{2x^2}*4x = 4e^{2x^2}x$

we have that f'(1) = 4e^2, hence the equation is

$y = f(1) + f'(1) (x-1) = e^2 + 4e^2(x-1)$

or, equivalently,

$y = 4e^2x - 3e^2$

Simplify the expression. 3(2y - 8) - 2y(5 - y)

seraphim [82]

Answer:

$\boxed{\bold{2y^2-4y-24}}$

Step By Step Explanation:

Expand $\bold{3\left(2y-8\right): \ 6y-24}$

$\bold{6y-24-2y\left(5-y\right)}$

Expand $\bold{-2y\left(5-y\right): \ -10y+2y^2}$

$\bold{6y-24-10y+2y^2}$

Simplify $\bold{6y-24-10y+2y^2}$

$\bold{2y^2-4y-24}$

The ratio of the lengths of the sides of a triangle ABC is 3:4:6. M, N, and K are the midpoints of the sides. Perimeter of the △

juin [17]

Given that in a trianlgle the sides AB, BC, CA are in the ratio 3:4:6.

Let AB = 3k, BC = 4k and CA = 6k.

Then perimeter =3k+4k+6k = 13k

M, N, K are mid points of the sides.

By mid point theorem MN = 3k/2, NK = 4k/2 and KM = 6k/2

Hence perimeter of MNK = 13k/2 =5.2 (given)

Solve for k

k=2(5.2)/13 = 0.8

Hence sides are

AB = 3k = 3(0.8) = 2.4 in

BC = 4k= 3.2 in

CA = 4.8 in

-3x-5y=15 what is the slope of this equation

goblinko [34]

Answer:

-3/5

Step-by-step explanation:

the customary way to determine the slope of a linear equation such as this one is to solve the equation for y:

-3x-5y=15 becomes -5y = 15 + 3x after 3x is added to both sides of the original equation.

Solving both sides of this latest result by -5 results in

y = -3 - (3/5)x

The coefficient of x (which here is 3/5) is the slope of this equation.
