loris [4]3 years ago
3 0

Step-by-step explanation:

  • Initial velocity (u) = 7 m/s
  • Final velocity (v) = 9 m/s
  • Time taken (t) = 2s

\dashrightarrow \quad \rm {a = \dfrac{v -u}{t} } \\

  • <em>a</em> denotes acceleration
  • <em>v</em> denotes final velocity
  • <em>u</em> denotes initial velocity
  • <em>t</em> denotes time

\dashrightarrow \quad \rm {a = \dfrac{9 -7}{2} \; m \: s^{-2}} \\

\dashrightarrow \quad \rm {a = \dfrac{2}{2} \; m \: s^{-2}} \\

\dashrightarrow \quad \underline{\boxed{\bf {a = 1 \; m \: s^{-2}}}} \\ (Answer)

A tank currently holds 5 gallons of water. It is being filled at the rate of 1/4 gallon per minute. How long will it take for th
Verdich [7]
So we know the tank already has 5 gallons and we need 9. This means we need 4 more gallons in order to fill up the tank.

If 1/4 gallon is being filled per minute we need to find out how many 1/4 gallons makes up 4 gallons in total.

4 of the 1/4 gallons makes up 1 whole gallon. So since we need 4 whole gallons we would need 16 of the 1/4 gallons.

This means that it will take 16 minutes for the tank to hold 9 gallons of water.

DENIUS [597]
Let s represent the number of sales, and t the total pay
the equation to represent this situation is t = 2s + 50
so set t to 100, and solve for s

100 = 2s + 50
50 = 2s
25 = s

you need to make at least 25 sales

Look at the graph shown<br> Which equation best represents the line?
Brilliant_brown [7]

y=\frac{11}{4}x +4 is the equation best represents the line.

Solution:

Take any two points on the line.

Let the points be (0, –4) and (4, 7).

x_1=0,y_1=-4,x_2=4, y_2=7

General form of equation of a line is y = mx + c

where m is the slope and c is the y-intercept of the line.

<em>y-intercept is the point which line crosses at y-axis.</em>

In the given line, y-intercept is 4.

c = 4

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{7-(-4)}{4-0}

$m=\frac{11}{4}

Equation of the line:

y = mx + c

y=\frac{11}{4}x +4

Hence y=\frac{11}{4}x +4 is the equation best represents the line.
