Scilla [17]
The area of the square= bxh
= 6x6= 36
The area of the rhombus is 4/5 the area of the square so 36x 4/5 = 28.8
Area of rhombus = basexheight
28.8= 6x height
Height = 28.8/6
Height =4.8

What is the slope of the line that goes through the points (-4,2) and (8,5)?
trapecia [35]

Hello,

y = ax + b where a is the slope

We have A(-4 ; 2) and B(8 ; 5)

a =  \frac{yb - ya}{xb - xa}  =  \frac{5 - ( - 4)}{8 - 2}  =  \frac{9}{6}  =  \frac{3 \times 3}{3 \times 2}  =  \frac{3}{2}

→ Slope : 3/2

The power generated by an electrical circuit (in watts) as a function of its current x xx (in amperes) is modeled by P ( x ) = −
marysya [2.9K]

Given:

The power generated by an electrical circuit (in watts) as a function of its current x (in amperes) is modeled by

P(x)=-15x(x-8)

To find:

The current which will produce the maximum power.

Solution:

We have,

P(x)=-15x(x-8)

P(x)=-15x^2+120x

Differentiate with respect to x.

P'(x)=-15(2x)+120(1)

P'(x)=-30x+120      ...(i)

To find the extreme point equate P'(x)=0.

-30x+120=0

-30x=-120

Divide both sides by -30.

x=4

Differentiate (i) with respect to x.

P'(x)=-30(1)+(0)

P'(x)=-30 (Maximum)

It means, the given function is maximum at x=4.

Therefore, the current of 4 amperes will produce the maximum power.
