Answer:

C. $11.55

Step-by-step explanation:

First, multiply 4 by $0.85 to get an answer of $3.40. Next, multiply 6 by $1.25 to get an answer of $7.50. Add up the cost of the pencils and pens by adding $3.40 and $7.50 to get $10.90. Next, we have to add the tax. Multiply $10.90 by 0.06 to get $.65. Add the $.65 to the $10.90 for a grand total of $11.55. Hope this helps!

What is the length of BC?

ELEN [110]

Answer:

Step-by-step explanation:

3x - 15 = x + 33 [sides opposite congruent angles in a triangle are congruent]
2x - 15 = 33 [subtract x from both sides]
2x = 48 [add 15 to both sides]
x = 24 [divide both sides by 2]
BC = 24 [BC = x]

Answer:

Step-by-step explanation:

a) x = 1.786 & -1.120

Explanation:

Turning points are points where the derivative equals zero. Solving the derivative for the values of X will give the answer to part a.

The derivative of this equation $x^3 =x^2-6x[/t[tex] is [tex]3x^2+2x-6$ .

Solving the equation $3x^2+2x-6=0$ using the quadratic formula we get 1.786 & -1.120

b) x = -3, x=0 and x=2

Explanation:

The solution to this equation are the points where the graph intersects with the x axis. Looking at the graph we can see that these points are -3 , 0 and 2
