Answer:

y = 6x + 4

Step-by-step explanation:

(x₁ , y₁) = (-2 , -8) & (x₂ , y₂) = (2 , 16)

$Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$= \frac{16-[-8]}{2-[-2}\\\\=\frac{16+8}{2+2}\\\=\frac{24}{4}\\\\= 6$

m = 6

y - y₁ = m(x - x₁)

y - [-8] = 6(x -[2])

y + 8 = 6(x + 2)

y + 8 = 6x + 6*2

y + 8 = 6x + 12

y = 6x + 12 - 8

y = 6x + 4

Answer:

300 feet

Step-by-step explanation:

If we were using feet the expression would be 198x, where x is feet per second

Since they are asking in meters we need to convert feet to meters

When you do that you get 60

Now the expression is 60x

When you plug 5 into the equation it is 300

Find the value of x

maks197457 [2]

Answer:

Step-by-step explanation:

∠S=180-(54+62)=180-116=64°

using sin formula

$\frac{x}{sin~64} =\frac{7}{sin~62} \\x=\frac{7~sin~64}{sin~62} \approx 7.1256 \approx 7.13$

Evaluate the limit as x goes to infinity of x^3e^-x/5

jekas [21]

Answer: 0

Step-by-step explanation:

$\frac{x^{3}e^{-x}}{5}$

This could be written as

$\frac{x^{3} }{5e^{-x} }$

Applying L'H rule and differentiating 3 times , we have

$\frac{6}{5e^{x} }$

taking the limit as x goes to infinity , we have
