.45 times 80

8 times 4 =32
8 times 0.5 =4

Just add these together to get 36.

Factor completely. -2k - k3^ - 3k^2

wlad13 [49]

Answer:

$-k(k+1)(k+2)$

Step-by-step explanation:

Begin to factor by using GCF by finding the greatest common factor. Here it is k.

$-2k-k^3-3k^2 = -k(2+k^2+3k)$

We will rearrange and factor the trinomial.

$-k(2+k^2+3k)\\-k(k^2+3k+2)\\-k(k+1)(k+2)$

If a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month, what

OLEGan [10]

Answer:

$97.15.

Step-by-step explanation:

We have been given that a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month. The interest rate of credit card is 3.35% monthly.

We will use interest formula to solve our given problem.

$I=PrT$ , where,

$I=\text{Interest}$ ,

$P=\text{Principal amount}$ ,

$r=\text{Interest rate in decimal form}$ ,

$T=\text{Time}$

Let us convert our given interest rate in decimal form.

$3.35\%=\frac{3.35}{100}=0.0335$

Upon substituting our given values in interest formula we will get,

$I=2,900*0.0335*1$

$I=2,900*0.0335$

$I=97.15$

Therefore, the monthly interest charge at the end of the 1st month will be $97.15.
