Not sure if this is correct but:

Step-by-step explanation: P = 2000

R = 5% = 0.05

n = 4

y = 2000 ( 1 + $\frac{0.05}{4}$ ) $^{4t}$ = 2000 ( 1.0125 )

Substitute values in the compound interest formula:

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

Hope this helps..

Find the original price of a salt lamp that is $76 after a 20% discount.

makvit [3.9K]

Answer:

$76 x 1.20 = $92

$92 / 1.20 = $76

To keep and show decimals we divide 20 by 100 to show 1.02 then show any 2 placement decimals if none are shown in draft first then you can try in draft 20/1000 to see the difference between the decimals.

How many different answers can you get by grouping differently? Add parentheses to the expression 7+3•4+2 to create new expressi

DiKsa [7]

Answer: The different possible solutions are 42, 21, 31 and 80.

Explanation:

The given expression is,

$7+3\cdot 4+2$

Case 1.

$(7+3)\cdot 4+2=10\cdot 4+2$

$(7+3)\cdot 4+2=40+2$

$(7+3)\cdot 4+2=42$

Case 2.

$7+(3\cdot 4)+2=7+12+2$

$7+(3\cdot 4)+2=21$

Case 3.

$7+3\cdot (4+2)=7+3\cdot 8$

$7+3\cdot (4+2)=7+24$

$7+3\cdot (4+2)=31$

Case 4.

$(7+3)\cdot (4+2)=10\cdot 8$

$(7+3)\cdot (4+2)=80$

Factor the trinomial completely <br><br> 3x^2-5x-2

nignag [31]

Answer:

(x − 2)×(3x+1)

Step-by-step explanation:

We can use this method:

$\begin{aligned}3 x^{2}-5 x-2 &=3 x^{2}-5 x-x+x-2 \\\\&=3 x^{2}-6 x+x-2 \\\\&=3 x \cdot(x-2)+(x-2) \\\\&=(x-2)(3 x+1)\end{aligned}$

All I did is Subtracting x then adding x which will not affect the result because -x + x = 0
