Find[f(x)] where f(x)=x-2 and g(x)=x+4/3

1 answer:

7 0

Answer: option B. x - 2/3

Explanation:

Something is missing in the question.

It seems the question if g [ f(x) ]

If that is so, then you have to find f(x) and use it as input of g(x).

This is:

g [ f(x)] = g [ x - 2]

g [ x - 2] = (x - 2) + 4/3 = x - 2 + 4/3 = x - 2/3, which is the option B.

which inequality best represents the statement. reduced movie price tickets are available for the following ages (a): children 1

Angelina_Jolie [31]

Answer:

13≥x U x≥65

Step-by-step explanation:

For a customer to have the reduced movie price tickets, they have to be 13 or younger, or 65 or older so I made the inequality, (X is less than or equal to 13) Union (X is greater than or equal to 65)

Can someone please help me with this!?

Katarina [22]

One way of solving this problem can be Heron's formula. It is a formula that allows us to compute the area of a triangle, knowing the length of its three sides.

For the sake of clarity, let's assume that the point in the top-left lies in the origin, and let's call it point A. Then, the "middle" point is point B, and the bottom-right point is point C.

If we fix the coordinate axis with the origin in A, we have the following coordinates for the three points:

$A = (0,0),\quad B = (4,-1),\quad C = (7,-5)$

We can compute the length of any side using the formula for the distance between two points:

$d(P,Q) = \sqrt{(P_x-Q_x)^2 + (P_y-Q_y)^2}$

Plugging the approriate values, we get the following lenghts:

$\overline{AB} = \sqrt{17},\quad \overline{BC} = 5,\quad \overline{AC} = \sqrt{74}$

Now that we have the lengths, we can use Heron's formula: given the side lenghts $a,b,\text{ and } c$ and the semiperimeter $p$ , the area is given by

$A = \sqrt{p(p-a)(p-b)(p-c)}$

If you plug our values, you will get an area of 6.5. So, unless I'm mistaken, none of the answers seem to mach, whereas 7 seems the best approximation.

47. Calculate the value of c in the triangle below.

TiliK225 [7]

Using the Pythagorean theorem

C = sqrt( 9^2 + 40^2)

C = sqrr(81 + 1600)

C = sqrt(1681)

C = 41 cm

Suppose that y varies directly with x

tiny-mole [99]

Answer:

15/2

Step-by-step explanation:

y varies directly as x can be written as:

y & x

y = Kx

K = y/x

But from the question, we were told that:

y = 10

X = 20

K = y/x

K = 10/20

K = 1/2

The formula for the expression is:

y = Kx

y = 1/2 x

Now let us solve for y, when:

x = 15

y = 1/2 x

y = 1/2 x 15

y = 15/2
