Your parents have a credit card with a balance of $3,287.90 at an interest rate of 14.5% APR. They pay $1,200.00 each month on t

Natali5045456 [20]

Answer:

$3,364.86

Step-by-step explanation:

3287.9*(14.5%/12)=39.73

3287.9 +39.73 interest = 3,327.63 - 1,200 (payment)=2127.63

2127.63 x (14.5%/12)=25.71

2127.63 + 25.71 interest = 2153.34 - 1200 (payment)=953.34

953.34 x (14.5%/12)=11.52

953.34 + 11.52 interest = 964.86

1200 + 1200 + 964.86 = $3,364.86

An equation of the line tangent to y=x^3+3x^2+2 at its point of inflection is

lys-0071 [83]

Answer:

y = 2

y = 6

Step-by-step explanation:

The first thing to do is to find the turning point of the function. For this, derive and equal zero to expression

$\frac{\delta y}{\delta x}$ = $3x^2 +6x$

$\frac{\delta y}{\delta x} = 0$

$3x^2 +6x = 0$

$3x(x +2) = 0$

x = 0 and x = -2

We have 2 inflection points.

Then we have 2 tangent lines:

At the point (0, 2)

Since it is a point of inflection, then the slope of this line is 0. Therefore the tangent line is:

y = 2.

At the point (-2, 6).

The slope of this line is 0.

The equation of the tangent line to the function is:

y = 6

At many bakeries, there are deals that if you buy twelve donuts, you get a thirteenth one at a discount. Sometimes "13" items is

Mariana [72]

Table

Number of donuts Price

1 $1.05

2 $ 2.1

3 $3.15

4 $4.2

5 $5.25

6 $6.3

10 $10.5

slope = (10.5 - 1.05) / 10 - 1

= 9.45 / 9

= 1.05

Equation

y - 10.5 = 1.05 (x - 10)

y = 1.05x - 10.5 + 10.5

y = 1.05x

For 40 donuts

y = 1.05(40)

y = $42
