If the radius is 4 feet like Clare says, the circumference would be 2(radius)(pi) which is 8pi.

If the diameter were 4 feet, circumference would be (diameter)(pi), which is 4pi.

You deposit $1500 in a stock account. The account starts losing 2.6% interest annually. How must money do you have after 2 years

Serhud [2]

Answer: M(2) = $1500*(1 - 0.026)^2 = $1423.01

Step-by-step explanation:

Initially in the acount there is $1500

You lose a 2.6% (or 0.026 in decimal form) per year, so after the first year you have:

M = $1500 - 0.026*$1500 = $1461

After other year, you lose oter 2.6%

M = $1461 - 0.026*$1461 = $1423.01

The equation can be writen as:

M(t) = $1500*(1 - 0.026)^t

Where t is the number of years, you can use t = 2 and get:

M(2) = $1500*(1 - 0.026)^2 = $1423.01

-5x-12>6x-4 Solve the inequality and give the answer in interval notation.

lora16 [44]

-5x-12>6x-4

To Solve the inequality we need to get x alone

-5x-12>6x-4

first we remove -12, for that we add 12 on both sides

-5x-12+12>6x-4+12

-5x > 6x +8

Now subtract 6x from both sides

-5x -6x> 6x-6x +8

-11x > 8

Divide by -11. when we divide by -11 we flip the inequality . so > becomes <

$x < -\frac{8}{11}$

We need to give the answer in interval notation.

x is less than -8/11 so x value starts from -8/1 and goes to -infinity(left)

So interval notation is (-∞, $-\frac{8}{11}$ )
