PLS HELP> is this a examples of speed velocity and acceleration. a plane flying 300 mi/hr west toward California

rusak2 [61]

Answer:

No

Step-by-step explanation:

Speed: 300 mi/hr, Gives how fast you go

Velocity: 300 mi/hr west, includes speed and direction

Acceleration: No, it does not say a starting speed or if it was a constant speed.

Hope this helps :)

If the hypotenuse is c=a√2, then 6=a√2. In inches, what is the value of a?

Aloiza [94]

The value of a is 3√2 inches if it is given that the hypotenuse is c = a√2 and 6 = a√2. This can be obtained by using Pythagoras' theorem.

<h3>Calculate the value of a:</h3>

This question can be solved using Pythagoras' theorem,

If in a right angled triangle, hypotenuse is the longest side of the triangle and always opposite to the angle 90°, height and base are the two shorter sides which are adjacent to the angle 90°.

If hypotenuse = c, height = a and base = b then,

⇒ hypotenuse² = height² + base²

⇒ c² = a² + b²

Here in the question it is given that,

Hypotenuse of the triangle is c = a√2
6 = a√2 in inches ⇒ c = 6

Height and base is equal and both has the value of a ⇒ height = a and base = a

By using the Pythagoras' theorem we can write that,

⇒ hypotenuse² = height² + base²

⇒ 6² = a² + a²

⇒ 36 = 2a²

By dividing both sides of the equation by 2,

⇒ 18 = a²

⇒ a² = 18

By taking square on both side of the equation,

⇒ a = 3√2 inches

Hence the value of a is 3√2 inches if it is given that the hypotenuse is c = a√2 and 6 = a√2.

Can some one please help me with this math question? Please and thank you

Bond [772]

Answer:

$V = 6373.2cm^3$

Step-by-step explanation:

Given

$V = \frac{4}{3}\pi r^3$ --- Volume

$D = 23cm$ --- Diameter

Required

Find the volume

First, we calculate the radius, r

$r = \frac{1}{2}D$

Substitute 23 for D

$r = \frac{1}{2} * 23$

$r = 11.5$

Substitute 11.5 for r in $V = \frac{4}{3}\pi r^3$

$V = \frac{4}{3} * \frac{22}{7} * 11.5^3$

$V = \frac{4*22*11.5^3}{3*7}$

$V = \frac{133837}{21}$

$V = 6373.19047619$

$V = 6373.2cm^3$

Answer:

$EF=6$

Step-by-step explanation:

In this problem, one is given a circle with two secants (that is a line that intersects a circle at two points). One is given certain measurements, the problem asks one to find the unknown measurements.

The product of the lengths theorem gives a ratio between the lengths in the secants. Call the part of the secant that is inside the circle (inside), and the part of the secant between the exterior of the circle and the point of intersection of the secants (outside). The sum of (inside) and (outside) make up the entire secant, call this measurement (total). Remember, there are two secants, ( $secant_1$ ) and ( $secant_2$ ) in this situation. With these naming in mind, one can state the product of the length ratio as the following:
