The overall NET change is 54 dollars...

THE TOTAL change is

|-130| + |240| + |-56|  =  426          Not?

First of all, get the VERTICAL component of the initial velocity:

V = 37m/s (sin(44.9) = 26.117 m/s

When the Vertical velocity equals ZERO, the projectile has reached its highest point (apex)

since v= vo + at     (vo = origianl velocity     a = acceleration of gravity = -9.80 m /sec^2   t = time)

ZERO=  26.117 + (-9.80 t)

Solving for t

-26.117 = -9.8 t

26.117/9.8 = t = 2.665 seconds

NOW,  use the position equation  pf = po + vt +1/2at^2   pf=Final position (max height...apex)

po = 0

so:

pf = 26.117 (2.665) + 1/2 (-9.8)(2.665)^2   =  69.60 + (-3.48) = 66.1 m   max height

your answer is 1,296.

x^4-7x^2-18 Factor please:

-130 + 240  - 56 =  +54 dollars

What is the approximate square root of 108 to the nearest integer?

e = 0

5x^3-x^2-20x+4 factor plezz :( 

=(x-2) (x+2) (5 x-1)

2z - 4 - z = 4      combine like terms on the left

z - 4  = 4    add 4  to both sides

z = 8

check:  2(8) - 4 - 8   =  16 - 4 - 8  = 16 - 12  = 4

Looking at 1/8 of the octagon, I'm assuming that we have something like this???

If so.......the small circles will overlap.......the larger enclosing circle will have its center at C and be tangent to the smaller circle at E....thus, its radius  = CD + DE  = 6.03553 + 2.5 = 8.53553 in. and the diameter will be twice this = about 17.07106 in. or about 17.07 in [rounded]

The "2z" and the "z" are like terms. That means, they can be simplified into only one term.

2z has a coefficient of 2.

z has an implied coefficient of 1.

You can combine the two terms to z. Think of it this way:

Reorder the equation, but keep the value the same. Switch the "-4" and the "-z". So, you have

2z - z - 4 = 4

Now factor out a "z" from the first two terms.

z (2 - 1) - 4 = 4

Simplify the (2 - 1) to 3.

3z - 4 = 4

Add 4 to both sides.

3z - 4 + 4 = 4 + 4

"- 4 + 4" simplifies to 0, and "4 + 4" simplifies to 8.

3z = 8

Now divide both sides by 3.

3z / 3 = 8 / 3

"3z / 3" The 3's cancel out, so you're left with just z. "8 / 3" cannot be simplified any more.

So your final answer is:           z = 8 / 3          or in decimal form         z = 2.6667

1cm=10mm

Use this formula to find out: Density=Mass/Volume

718/30  = 23 boxes filled and 28 trains left over

\(\dfrac a b = a \times \dfrac 1 b\)

\(\dfrac {15}{2/3}=15 \times \dfrac 3 2 = \dfrac {45} 2\)

please someone telll me how to do this project

If, by "nothing,"  you mean "zero,"   ....the answer is no....we cannot divide by zero

how do I write an equation of the perpendicular line 5y=x-10 through (3,-4)?

The slope of the given line = (1/5)

So the slope of our perpenducular line is the negative reciprocal of (1/5) = -5

And we can use the point-slope form to write

y - (-4)  = -5(x - 3)

y + 4 = -5x + 15

y = -5x + 11      this is in slope-intercept form
