F(x) = x^2 +3x-2<br> F(a) = ?<br> find F(x) for the given domain.
Delvig [45]

Answer:

<em>a^2 +3a-2</em>

Step-by-step explanation:

Given the expression:

g(x) =  x^2 +3x-2

We are to find f(a). To get this, we will simply replace x with a in the expression as shown;

g(a) = a^2 +3a-2

<em>hence the required domain is expressed as g(a) = a^2 +3a-2</em>

Is m=10 and m=-10 is it parallel lines or perpendicular
MakcuM [25]

Neither, for lines to be parallel they have to have the same slope, and for lines to be perpendicular they have to be the negative reciprocal of the slope of the other line. In this case, the line perpendicular to the line with slope m=10 would be m=1/-10 or -1/10

Math/Physics Problem <br> (I'd be glad if you solved one of them).
Whitepunk [10]

Answer:

19.2

76.8

Step-by-step explanation:

density × volume = mass

mass = 62.4 × (pi × (40/2)² × h)

mass = 78,374.4h

WD = m×9.8×h = 9.8mh

WD = 768,069.12h²

At h = 5

WD = 768,069.12×5²

= 19,201,728 ft-lb

= 19.2 million ft-lb

At h = 10

WD = 76,806,9.12 × 10²

WD = 76,806,912 ft-lb

= 76.8 million ft-lb
