You are saving money to buy a used car. You deposit $2,500 in an account that earns interest compounded annually. The expression
seraphim [82]

Answer:

r= [(\frac{A}{2500}) ^\frac{1}{2} -1]

Step-by-step explanation:

Given data

Principal = $2500

time t= 2 years

Required

the rate r

Given the expression for the balance 2500(1+r)^2

Hence

A= 2500(1+r)^2

we can make r subject of formula

r= [(\frac{A}{P}) ^\frac{1}{t} -1]

r= [(\frac{A}{2500}) ^\frac{1}{2} -1]

Hence, for any value of A, we can find the rate using the expression above

_ please answer this question .
Anna007 [38]

Answer:

For the column "Slope Intercept", the graph is displaying y = -7/2x + 3. Because the line is going down 7 units and to the right 2 units, and the 3 is the point in which the line crosses the y-axis.

For the "Standard" column, it will be

7x + 2y = 6, because that's what it would look like in standard form. (To turn it from standard to slope intercept form, remember you must first subtract 7x on both sides to get 2y = -7x + 6, and then divide by 2 on both sides to get

y = -7/2x + 3.)

For column "Point Slope", I just realized you are supposed to pick a point on the line and plug the coordinates into this formula:⤵⤵⤵

<em>This is the point-slope formula.⤵⤵⤵</em>

y - y _{1} = m(x - x _{1})

For example we'll use point (2,-4). Also, remember that coordinates are written as (x,y), and that m represents slope.

So we have: y - (-4) = -7/2(x-2).

In other words, "Point Slope" would be

y + 4 = -7/2(x-2).

By the way, sorry this is a bit long, and took a while to complete. I had to re-educate myself on point-slope. Anyways hope this helps, I tried :)

Ella says the answer to $79 ÷ 4 is $19.30. What did she do wrong?
Mamont248 [21]

Answer:

19.75

Step-by-step explanation:

while she divided the remainder 3 (then you bring down the 0) she accidentaly put 30 in 19.30 so thats why

while the correct way is to keep going with the equation until you have no remainder

hodyreva [135]

Answer:

Well I recently tore my meniscus a little bit, but you said yours popped/locked, I don't think mine did that. But it could be a bigger meniscus tear then mine, don't take my word for it tho, I'm no orthopedic or doctor. And for the second time in 7-9 months?? I'd definitely go get that checked out if you can.
