How long does it take to drive 272 miles going 68mph

272mi/68mi/hr= 4 hr

Example:
Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario. 

Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds 

Solution: 
A = 45 m/s – 15m/s / 6s 
A = 5m/s^2

♥ It is going to take you 4 hours to drive 272 by going 68mph.
To do this you need to divide.
♥ 272/68=4

Answer:

The length of the three sides $5, \sqrt{58} , \sqrt{65}$

The triangle is not a right triangle

Step-by-step explanation:

A = (3, 2) , B = ( 6, 9) , C = (10, 6)

Find the lengths using distance formula.

$distance = \sqrt{(x_2 -x_1)^2 + (y_2 - y_1)^2}$

$AB = \sqrt{(6-3)^2 + (9-2)^2} = \sqrt{9 + 49 } = \sqrt{58}$

$BC = \sqrt{(10-6)^2 + (6-9)^2} = \sqrt{16 + 9} = \sqrt{25} = 5$

$AC = \sqrt{(3-10)^2+(2-6)^2} = \sqrt{49 + 16} = \sqrt{65}$

Using Pythagoras theorem :

$(Longer \ side)^2 = sum \ of \ square \ of \ two \ other \ sides$

Longest side is AC . So we will check if it satisfies Pythagoras theorem :

$\sqrt{65} = \sqrt{58} + 5^2\\65 = 58 + 25\\$

65 ≠ 58 + 25

So the sides does not satisfy Pythagoras theorem. Hence the triangle is not a right triangle.

Eight taken away from five is equivalent to fourteen.

Thirteen added to seven equals five.

I don't understand the equation itself, but if those equations were to be actually written the way they were, then the above sentences are correct.

HELPP Let f(x) represent a function. Which descriptions match the given transformations? Drag and drop the answers into the boxe

kap26 [50]

f(x+5/4) means that f(x) is translated 5/4 units left. f(x-5/4) means that f(x) is translated 5/4 units right. f(x)-5/4 means that f(x) is translated 5/4 units down. f(x)+5/4 means that f(x) is translated 5/4 units up. f(x*5/4) means that f(x) is compressed by a factor of 5/4. f(x/5/4) means that f(x) is stretched by a factor of 5/4.
