Answer:

4^4= 4^-1(3r+2)

4^4= 4^(-3r-2)

-3r-2 = 4

-3r= 6

r= -2

Answer:

The answer to your question is Area = 6 u²

Step-by-step explanation:

Process

To find the area of the picture divide the figure between a square and a right triangle, determine the area of each figure and finally add them up.

1.- Calculate the area of the square

Area = side x side

        = 2 x 2

        = 4 u²

2.- Calculate the area of the triangle

Area = base x height / 2

base = 2   height = 2

Area = 2 x 2 /2

Area = 2 u₂

3.- Total area

Area = 4 + 2

       = 6 u²

which has greater cenetic energy a car traveling 30.0 km/hr or one twice as heavy traveling at 15 km/hr?​
iVinArrow [24]

Answer:

30 km/h car

Step-by-step explanation:

From analysis the   car traveling at 30 km/h has greater kinetic energy

we can deduce it from the expression of kinetic energy which is

KE=\frac{1}{2} mv^2

Assuming the mass m= 1 kg

 

For the 30 km/h

KE=\frac{1}{2}*1*30^2 \\\\KE=\frac{1}{2}*1*900\\\\\KE=450 J

   

For the 15 km/h

KE=\frac{1}{2}*2*15^2 \\\\ KE=\frac{1}{2}*2*225 \\\\\ KE=\frac{1}{2}*450 J\\\\\ KE=225 J

Though the kinetic energy is a function of mass and velocity, but from our analysis the faster moving object has more KE

<em><u>Question:</u></em>
<em>Mrs. Magdalino kept records on how much she spent on gasoline and the maintenance of her car.  She found that it cost $485 to drive 500 mi in a month.</em>
<em>a)  Find the cost per mile.  Write an equation that relates the cost c for gasoline and maintenance of a car to the number of miles m the car is driven.</em>
<em>b)  Use the equation to find the cost for driving 1200 miles.</em>
<em>c)  About how many miles are driven for a cost of $820?</em>

<em><u>Answer:</u></em>
a)
$485/500mi = <u><em>$0.97/mi</em></u>

c = cost
m = miles driven

cost per miles driven = cost / mile driven = <u><em>c/m</em></u>

b)
(1200 mi)*($0.97/mi) = <u><em>$1164</em></u>

c)
(x miles)*($0.97/mi) = $820

*divide both sides by $0.97/mi

x miles = $820/($0.97/mi)

<u><em>x = 845.36 miles</em></u>
