Answer:

muscle contraction

…active muscles are produced by cross-bridges (i.e., projections from the thick filaments that attach to the thin ones and exert forces on them). As the active muscle lengthens or shortens and the filaments slide past each other, the cross-bridges repeatedly detach and reattach in new positions.

4^2 + b^2 = 12^2
16 + b^2 = 144
B^2 = 144-16
B^2 = 128
B= 11.3

Fifteen more than half a number is 9

rusak2 [61]

For this case, the first thing we must do is define a variable.

We have then:

x: unknown number

We now write the equation that models the problem:

$(\frac{1}{2}) x + 15 = 9$

From here, we clear the value of x.

We multiply both sides of the equation by 2:

$(\frac{2}{2}) x + 2 (15) = 2 (9)\\x + 30 = 18$

We subtract 30 on both sides of the equation:

$x + 30 - 30 = 18 - 30\\x = -12$

Answer:

The value of the unknown number is given by:

$x = -12$

If the graph of f(x) has the point (2,7) then what is one point that will be on the graph of f-1(x)

IRINA_888 [86]

The graph of f^-1 (x) is called the inverse function of f (x). The relationship between the two is that the point (x,y) is on the graph of f (x) if and only if the point (y,x) is on the graph of f^-1 (x).

This means that if the point (2, 7) is on f (x), therefore the point (7, 2) is on f^-1 (x).

Answer: (7, 2)

Answer:

B. 15

Step-by-step explanation:

The chances of randomly selecting keys for a sports car or convertible is 5/40 since there are a total of 5 sports and convertible car keys and a total of 40 keys overall. We then multiply that 5/40 by 120 because Sam randomly selects a key 120 times.

5/40 × 120 = 15
