Answer & Step-by-step explanation:

Simplifying

5n = 3000

Solving

5n = 3000

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Divide each side by '5'.

n = 600

Simplifying

n = 600

Answer: L ≈ 2.0 m

Step-by-step explanation:

Lsin40 = h

Lsin55 = h + 0.35

Lsin55 = Lsin40 + 0.35

Lsin55 - Lsin40 = 0.35

L(sin55 - sin40) = 0.35

L = 0.35 / (sin55 - sin40)

L = 1.98452 ≈ 2.0 m

Ax+ay+xa+ya Differentiate

Dmitry_Shevchenko [17]

Answer:

2 a

Step-by-step explanation:

Possible derivation:

d/dx(2 a x + 2 a y)

Differentiate the sum term by term and factor out constants:

= 2 a (d/dx(x)) + d/dx(2 a y)

The derivative of x is 1:

= d/dx(2 a y) + 1 2 a

The derivative of 2 a y is zero:

= 2 a + 0

Simplify the expression:

Answer: 2 a

Find the slope-intercept form of the equation of the line through the point (0, -4) and (1, 0).

Arisa [49]

Answer:

The Slope Intercept form of the equation through the point (0, -4) and

(1, 0) is y = 4 x - 1

Step-by-step explanation:

Here, the given points are A (0,-4) and B(1,0)

Now, slope of the equation with points (a,b) and (c,d) is given as

$m = \frac{d - b}{c -a}$

So, here the slope of the line AB is given as:

$m = \frac{0 - (-4)}{1-0} = \frac{4}{1} = 4$

⇒ m = 4

Now, by POINT SLOPE form:

The equation with slope m and point (x0 , y0) is represented as :

(y-y0) = m (x-x0)

⇒ The equation of AB is of the form with point (1,0) is

y - 0 = 4 (x -1)

or, y = 4 x - 1

Also, the SLOPE INTERCEPT form of an equation is of the form

y = m x + C ; m = slope and C = y -intercept

Hence, the slope intercept form of the equation through the point (0, -4) and (1, 0) is y = 4 x - 1
