Credit card A has an APR of 20.8% and an annual fee of $60, while credit card B has an APR of 24.6% and no annual fee. All else

being equal, which of these equations can be used to solve for the principal, P, the amount at which the cards offer the same deal over the course of a year? (Assume all interest is compounded monthly.) A. P•(1 + 0.208/12)12 - $60•12 = P•(1 + 0.246/12)12 B. P•(1 + 0.208/12)12 + $60•12 = P•(1 + 0.246/12)12 C. P•(1 + 0.208/12)12 - $60 = P•(1 + 0.246/12)12 D. P•(1 + 0.208/12)12 + $60 = P•(1 + 0.246/12)12

Answer:

Option D is right answer.

Step-by-step explanation:

Given APR of card A = 20.8%, monthly rate is 0.208/12

n = 12 as interest is compounded monthly.

t = 1 year

The annual fee of card A is $60.

So, formula for compound interest is $A=P(1+\frac{r}{n})^{nt}$

Putting the values in formula:

A= $P(1+0.208/12)^{12}$ +60 (annual fee)

For card B :

APR is 24.6% or monthly 0.246/12

n = 12 and t = 1

Putting these values in formula :

$A=P(1+0.246/12)^{12}$

Hence, as per the result from formulas, we can see that option D is correct one.

Inequalities are used to show the relationship between unequal expressions

<em>The set notation of (5) and (6) are: </em> $\{x : -6 > x \ge -2\}$ <em> and </em> $\{x:-4 < x \ge 6\}$ <em>.</em>
<em>See attachmen</em>t for the graphs

The following should be notated when plotting the graph of an inequality

< and > are represented with open circles, while $\leq$ and $\geq$ are represented with closed circles
The arrows of and $\le$ point to the left, while the arrows of $>$ and $\geq$ point to the right.

So, we have:

$(a)\ -8 < x$

Rewrite as:

$x > -8$

The graph of $x > -8$ will point to the right, and it will use an open circle

$(b)\ -6 > x \ge -2$

Split the inequality:

$-6 > x$ and $x \ge -2$

<em>It is not possible for -6 to be less than x and at the same time, x is greater than or equal to -2.</em>

<em />

Hence. $-6 > x \ge -2$ cannot be represented on a graph

$(c)\ -4$

Split the inequality:

$-4 < x$ and $x \ge 6$

$-4 < x$ means that -4 is less than x or x is greater than -4.

So, we have:

$x > -4$ and $x \ge 6$

If $x > -4$ and $x \ge 6$ , then we make use of $x > -4$ because it contains more values of x.

The graph of $x > -4$ will point to the right, and it will use an open circle

Help me with this I can’t figure it out

Stella [2.4K]

Answer:

y = 4x+6

The input is 11 when the output is 50

Step-by-step explanation:

We need to find the slope of this function using 2 points

(3,18) and (0,6) are two points

m = (y2-y1)/(x2-x1) is the formula for slope

=(6-18)/(0-3)

-12/-3

=4

The slope is 4

We know the y intercept. It is the value when x =0. The y intercept is 6

We can use the slope intercept form of the equation

y = mx+b, where m is the slope and b is the y intercept.

y = 4x+6

We want to know the input when the output is 50 (or y=50)

50 = 4x+6

Subtract 6 from each side

50-6 = 4x+6-6

44 = 4x

Divide by 4

44/4 = 4x/4

11=x

The input is 11

What is the domain of the relation y = arccscx?

Stella [2.4K]

Answer:

$y=arc\csc x$

Step-by-step explanation:

The given function is $y=arc\csc x$ .

The domain refers to all values of x for which this function is defined.

Recall that: the domain of $y=arc \sin (x)$ is $-1\le x\le1$

And we know $y=arc\csc x$ is the reciprocal of $y=arc \sin (x)$ .

Therefore the complement of the domain of $y=arc \sin (x)$ which is $(-\infty,-1]\cup [1,+\infty)$ is the domain of $y=arc\csc x$

Erin created a scale drawing for a garden that will be 10 ft by 5 ft. She plans to include a section in the garden for herbs, wh

Elanso [62]

Answer:

The dimensions of the herb garden in the scale drawing are 2.4 in. by 6 in

Step-by-step explanation:

we know that

The dimensions of the garden in the actual are 10 ft by 5 ft

The dimensions of the garden on the scale drawing are 12 in. by 6 in

step 1

Find the scale factor

To find the scale factor divide the corresponding side on the scale drawing by the corresponding side in the actual

so

$\frac{12}{10}\ \frac{in}{ft}$

simplify

$1.2\ \frac{in}{ft}$

That means

1.2 inches in the drawing represent 1 foot in the actual

step 2

Find out the dimensions of the herb garden on the scale drawing

we know that

The dimensions of the herb garden in the actual are 2 ft by 5 ft

Multiply by the scale factor

so

$2\ ft=2(1.2)=2.4\ in$

$5\ ft=5(1.2)=6\ in$

therefore

The dimensions of the herb garden in the scale drawing are 2.4 in. by 6 in
