<u>Answer:</u>

Piston displacement = 84.8

<u>Step-by-step explanation:</u>

We will find the volume of the cylinder in order to find the piston displacement.

Here, (bore = diameter, so r = diameter/2) (height = stroke)

Volume = \pi r^2h =3.14\times1.5^2\times 3 = 21.2 cubic units

Since the engine has 4 cylinders, so we will multiply the piston displacement by 4 to get:

Piston displacement = 21.2 \times 4 = 84.8

Answer: The first radio button choice  8/3 * m^8


Steps:

120 (m^ 16)  /  45 (m^8) =

120/45  *  (m^16)/(m^8) =

Simplify 120/45  (15 or 5 *3 divides each). Since base "m" is same in both terms simply subtract exponents.

8/3  (  m^(16 - 8))  =

8/3 * m^8

A flagpole is supported by a wire fastened 60 feet from its base. The wire is longer than the height it reaches on the flagpole.
maxonik [38]

Answer:

135.5ft

Step-by-step explanation:

THIS COMPLETE THE QUESTION

flagpole is supported by a wire fastened 60 feet from its base. The wire is 14 feet longer than the height it reaches on the flagpole. Find the length of the wire.

Let X be the length of the wire

Let y be the height of the pole

X= Y + 14

Y= X -14

We can form a right angle triangle form this, where X denote the Hypotenose, Y is the Opposite, and 60feet is the Adjacent.(CHECK THE ATTACHMENT FOR THE TRIANGLE)

Using Pythagoras theorem

X²= 60² + Y²

X² = 3600 + Y²

if we subsitute for Y we have

X² = 3600 + (X -14)²

X² = 3600 +X² -14X-14X+196

X²-X²+ 28X= 3600+196

28X= 3796

X= 3796/28

=135.5ft

hence length of the wire is 135.5ft

Answer: D. 7^11

Step-by-step explanation:

For exponents with the same base, we just add the exponents and keep the same base. 7 is the same base; therefore 5+6=11 which means the answer is 7^11
