Hi :)

Ok, well- solve the equation first, then maybe from there we will have more ideas on what to do here.

So:

(x - 6)(x + 2) = 0

Set factors equal to 0

x - 6 = 0 or x + 2 = 0

x = 0 + 6 or x = 0 - 2

x = 6 or x = -2

Now we can answer the questions....

1) For (x - 6)(x + 2) to equal 0, either (x - 6) or (x + 2) must equal 0

2) In order from least to greatest, are -2 and 6

Let me know if you have any questions. As always, it is my pleasure to help students like you!

6r - 7 over 10 = r over 4

Ahat [919]

Multiply both sides by 4

subtract 24r from both sides

simplify r - 24r to -23r

divide both sides by -23

two negatives make a positive

simplify 14/5/23 to 14/5 x 23

simplify 5 x 23 to 115

switch sides

Answer: r = 14/115.

A bank advertises that it compounds money quarterly and that it will take Double your money in 10 years. what is the interest-ra

S_A_V [24]

The interest rate is 6.992%, if a bank advertises that it compounds money quarterly and that it will take Double your money in 10 years.

Step-by-step explanation:

The given is,

Compounds money quarterly

Double your money in 10 years

Step:1

Formula to calculate future investment with compounded quarterly,

$A =P(1+\frac{r}{n} )^{nt}$ ...............................(1)

Where, A - Future amount

P - Initial investment\

r - Rate of interest

n - No. of compounding in a year

t - No. of years

Step:2

Let, P = X

A = 2X ( Double your money )

From given, n - 4 ( for compounding quarterly )

t - 10 years

From equation (1)

$2X =X(1+\frac{r}{4} )^{(4)(10)}$

$\frac{2X}{X} =(1+\frac{r}{4} )^{(4)(10)}$

$2 =(1+\frac{r}{4} )^{40}$

Take root $40^{th}$ root on both side,

$\sqrt[40]{2} = (1+\frac{r}{4} )$

$1.017479692 = (\frac{4+r}{4} )$

$(1.017479692)(4) = (r+4)$

$4.06992=(r+4)$

$r = 4.06992 -4$

$r =( 0.06992)(100)$

r = 6.992 %

Result:

The interest rate is 6.992%, if a bank advertises that it compounds money quarterly and that it will take Double your money in 10 years.

What is<br> as a decimal rounded to 3 decimal places?

puteri [66]

“Three decimal places” is the same as “the nearest thousandth.” So, for example, if you are asked to round 3.264 to two decimal places it means the same as if your are asked to round 3.264 to the nearest hundredth. Some questions, like the example below, will ask you to “show your answer correct to two decimal places."
