Answer: 9.17cm

Since it is a right angle triangle, we can use Pythagoras Theorem to find the missing leg.

-------------------------------------------------
Formula
-------------------------------------------------
a² + b² = c², c being the hypotenuse.

The hypotenuse, denoted by c, is 10cm. One leg, denoted by a, is 4cm. Apply the formula and solve for the other leg, denoted by b.

-------------------------------------------------
Solve the missing side
-------------------------------------------------
a² + b² = c²
4² + b² = 10²
16 + b² = 100 ←subtract 16 from both sides
-16 -16
b² = 84 ←square root both sides
b = √84
b = 9.17 (nearest hundredth)

So the other leg, denoted by b, is 9.17cm

Answer: 9.17 cm

Bill is making accessories for the soccer team. He uses 838.95 inches of fabric on headbands for 32 players and 3 coaches. He al

creativ13 [48]

There was 23.29 inches used on a headband for each player.

And 8.54 inches used on a wristband for each player.

To find out how much fabric for headbands and would beused for each player/person you would do

So, if you substitute the values in it is

And finally, to find how much fabric is used on a wristband for each player/person you would use the same formula.

There are 3 inches of snow on the ground when it begins to snow 0.5 inches per hour.

algol [13]

The answer is y=0.5x+3

There are 3 inches of snow on the ground: y = 3
When it begins to snow 0.5 inches per hour: y = 0.5x
There are 3 inches of snow on the ground when it begins to snow 0.5 inches per hour: y = 0.5x + 3

A map has a scale of 3 cm 18 km in Riverside Riverside in Smithville are 54 km apart then they are how far apart on the map

kotegsom [21]

Divide actual km by scale km:

54/18 = 3

Multiply scale cm by that:

3 x 3 = 9

They are 9cm apart on the map

The graph shows the function f(x) which equation represents f(x)?

Elan Coil [88]

Some times it's really very easy to answer the problem just by looking over the given problem.

For the given graph, we need to observe some(or any) point on the graph that can conclude anything to answer the given problem.

Generally we observe x or y-intercepts of the graph first.

Let us observe the y-intercept of the given graph, because we can see a clear picture of y-intercept there.

By looking on the graph, we can see y-intercept is at -1.

Note: y-intercept is a point on y-axis where value of x is 0.

Now let us observe the given functions in the given options.

First option: If we plug x=0 in the given function, we get f(0)=0.

So, y-intercept for first option is 0.

Second option: If we plug x=0, we get a negative -1 inside radical. Cube root of -1 is -1. On multiplying by -1 we get +1.

So, y-intercept for second option is 1.

Third option : If we plug x=0 in that function, we get 0-1 = -1.

So, the y-intercept for third function is -1.

Therefore, function in third option is the correct function for given graph.

Therefore, third option $f(x)=\sqrt[3]{-x}-1$ is correct option.
