For instance, 20 miles square (20 × 20 miles) is equal to 400 square miles; an area of 10 × 40 miles is likewise 400 square miles, but it is not 20 miles square. One square mile<span> is equal to: 4,014,489,600 square inches. 27,878,400 square feet.</span>

Answer:

Initiation fee:

$400

Monthly fee:

$10

Step-by-step explanation:

First, let's start by calculating the monthly fee.

Over a period of 5 months (5 -> 10 months), the member paid 50 dollars more. We can divide this number by 5 to find the monthly fee. The monthly fee is $10.

Now, we can find the initiation fee. After 5 months with the gym, the member had spent $450. As we already know, $50 is the price for 5 months, so the member paid $50 in monthly fees.

We subtract $50 from the total cost ($450) to find that the initiation fee is $400.

Now, we can write the equations for each statement.

<em>Let m represent the monthly fee and i represent the initiation fee:</em>

"At the end of 5 months, a member had paid a total of $450"

5m + i = 450

"At the end of 10 months, she had paid a total of $500.

You could use 2 equations for this statement:

10m + i = 500

OR, if you use the above facts to calculate the fact that there was a $50 increase from those five months, and exclude the initiation fee and the previous five months:

5m = 50

Hope this helps!

Please help me determine the equation of the line in slope intercept form and show all work. A line that is perpendicular to the

Airida [17]

Answer:

y=-2x+160

Step by Step:

The equation of a line can be determined using the point slope formula:

y-y1=m (x-x1)

To make a substitution, we must ensure we have the correct information. The question gives:

y1=60

x1=50

y=1/2x+10 This is the formula of a line that is perpendicular to the one we are trying to find.

It tells us that the gradient of the perpendicular line is 1/2. The gradient of the line we are trying to find can be found using m1×m2=-1 because we know that when lines are perpendicular, the product of their gradients must equal 1

So if we replace m1 with 1/2

1/2×m2=-1

m2=-2

We now have all the relevant information to make a substitution:

y-60=-2 (x-50)

expand brackets

y-60=-2x+100

rearrange to get in the form y=mx+b

y=-2x+160

Find parametric equations for the path of a particle that moves along the circle x2 + (y − 3)2 = 16 in the manner described. (en

sveticcg [70]

Answer:

$x(t) = 4 cos(-t)\\y(t) = 4 sin(-t) + 3\\$

and t ∈ [0,2π]

Step-by-step explanation:

The standard equation for circle is:

$(x-h) ^2 + (y-k)^2 = r^2$

Comparing our equation with standard

$x^2 + (y-3)^2 =16$

h= 0,

k= 3

r= 4 (as in standard r², so r =√ r²)

Required:

Parametric equations of the circle

Formula:

$x = r cos(t) + h\\y= r cos(t) +k$

Putting values of r and h and k we get

$x= 4 cos(t) + 0 \\x= 4 cost(t) \\y= 4 sin(t) + 3$

As we need to start the object at (4,3)

x(0) = 4 and y(0) = 3

and the period is 2π

As the rotation is starting clock wise we will invert the value of t i.e -t

$x(t) = 4 cos(-t)\\y(t) = 4 sin(-t) + 3\\$

and t ∈ [0,2π]

The price of a DVD is $19 . The price is 12% lower than last week.

grandymaker [24]

Here is the solution for the given problem above.
First we need to get the 12% of $19. So 19 x 0.12 and we get 2.28. So in order to get the price of the DVD last week, let us add the 2.28 to 19, and we get a total of 21.28. So the final answer would be: $21.28 is the price of the DVD last week. Hope this answers the question. Thanks for posting your question.
