HELP<br> Write an equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1

MArishka [77]

The line is parallel so it has the same slope as the other line, -4.

Substitute the x and y variables with the given points and find the y-intercept.

(-8, 6)

y = -4x + b

6 = -4(8) + b

6 = -32 + b

6 + 32 = b

38 = b

So the equation is:

y = -4 + 38

The power generated by an electrical circuit (in watts) as a function of its current c (in amperes) is modeled by: P(c)= -12c^2

sveta [45]

Answer:

5 amperes will produce the maximum power

Step-by-step explanation:

The power generated by an electrical circuit (in watts) as a function of its current c (in amperes) is modeled by: P(c)= -12c^2 + 120c.

To find out the maximum power we need to find the vertex

formula to find x -coordinate of vertex is $\frac{-b}{2a}$

P(c)= -12c^2 + 120c is given in the form of y=ax^2+bx+c

a= -12, b = 120

$c=\frac{-b}{2a}=\frac{-120}{2(-12)}=5$

c= 5 amperes will produce the maximum power

For any positive numbers a, b, and d, with b 1,

Vitek1552 [10]

Answer:

Step-by-step explanation:

using the rule of logarithms

log x - log y ⇔ log ( $\frac{x}{y}$ )

then

$log_{b}$ ( $\frac{a}{d}$ ) = $log_{b}$ a - $log_{b}$ d
