Use subtraction to find the lengths of segments WX and XY.

Point W is on (9,3), point X is on (5,3) and point Y is on (5,9), if I'm reading this correctly. 

Point W and point X match with their y-values, so we ignore them. Subtract the x-values, 9 and 5, to get the length. In this case, the length is 4 units. 

Point X and point Y match with their x-values, so we ignore them. Subtract the y-values, 3 and 9, to get 6. 

Since the problem is asking for length, you always subtract the smaller number from the larger one, as you can't have a negative distance or length.

PLEASE SOMEONE HELP I TRULY DO NOT UNDERSTAND

Hi there!

\large\boxed{f^{-1}(x) =  \sqrt[3]{\frac{x+4}{9} } }

f(x) = 9x^{3} - 4

Find the inverse by replacing f(x) with y and swapping the x and y variables:

x = 9y^{3} - 4

Isolate y by adding 4 to both sides:

x + 4 = 9y^{3}

Divide both sides by 9:

\frac{x+4}{9}= y^{3}

Take the cube root of both sides:

y = \sqrt[3]{\frac{x+4}{9} }\\\\f^{-1}(x) = \sqrt[3]{\frac{x+4}{9} }

With a headwind a plane traveled 128 km in 2h. The return trip with a tail wind took 24 min less. Find the air speed of the plan
sertanlavr [38]

Based on the information given, it can be noted that the air speed that the plane has will be 71.1 km per hour.

The number of hours used for the return trip will be:

= 2 hours - 24 minutes.

= 1 hour 36 minutes.

= 1.6 hours.

Therefore, the speed of the air plane will be:

= (128 + 128) / (2 + 1.6)

= 256/3.6.

= 71.1 km per hour.

Thalia has a circular pool in her backyard. The diameter of the pool is 10 ft. Explain in writing (typing) how to find the radiu
Vesna [10]

Answer:

Since the diameter of the pool is 10 feet, the radius will be one-half of the diameter.

The radius will be 5 feet.

The circumference of the pool will be Pi times the diameter.

The circumference will be Pi (3.14) times 10 feet.

The circumference will be 31.4 feet.
