The function for the length when the width is given is l = 33 - w. The domain of the function is 0 < w < 33 and the graph of the function has been plotted

The total length of the roll = 66 feet

The perimeter of the rectangular paly area = 66

The perimeter of the rectangle = 2(l + w)

Then the equation will be

2(l + w) = 66

l + w = 66/2

l + w = 33

The function for length when the width is given

l = 33 - w

Therefore the domain of the function is 0 < w < 33

When w = 1

l = 33 - 1

l = 32

The first point is (1, 32)

When w = 32

l = 33 - 32

l = 1

The second point is (32, 1)

Draw the graph of the function

Hence, the function for the length when the width is given is l = 33 - w. The domain of the function is 0 < w < 33 and the graph of the function has been plotted

Answer: B

Step-by-step explanation:

Interest will he pay in 10 years is $3375.

Given:

Bill is a freshman attending a 4-year college. He has been approved for a $5,000 with an APR of 6.75%.

He is not required to make any payment for 10 years since his payment will be deferred while his enroll in school.

1 year interest = 5000*6.75%

= 5000*6.75/100

= 50*6.75

= 50*675/100

= 1*675/2

= 337.5

10 years interest = 10 * 337.5

= 10 * 3375/10

= $3375.

Therefore Interest will he pay in 10 years is $3375.

The amount  that he invested in Fund B if the total profit from the two funds together was $2200 is $8,800.

Let x represent the amount invested in Fund B

Let 3x represent the  amount  invested in Fund A

Hence,

.07x + .05(3x) = 2200

.07x + .15x = 2200

.25x = 2200

Divide both side by .25x

x = 2200/.25

x = $8,800  (invested in Fund B)

Fund A:

3x = 3(8,800)

3x = $26,400 (Invested in Fund A)

Answer:

16.11 (appx.)

Step-by-step explanation:

since l and m are parallel and a line intersects them, so we can say that the line is the transversal. from the figure we see that

7x + 12 = 12x - 28 [they are internal alternate angles and alternate angles are always equal to one another]

now, we can find the value of x from the equation

12x - 7x = 28 + 12

⇒ 5x = 40

⇒ x = 8

so the angle (7x+12)° is ((7*8)+12) = 68°

so (12x-28)° is also equal to 68° [cause of being alternate angles]

now, look at the figure,

angle (9y-77)° & (12x-28)° add upto a straight line as in 180°

and we know (12x-28)° = 68°

so now,

9y-77 = 68

⇒9y = 68+77

⇒9y = 145

⇒y = 16.11 (appx.)

Jillian made the exact amount was $1598 in 3 weeks.

Each t-shirt costs $15.

Each Large purse goes for $59

And the cost of small purses is $32 each.

In the first week, she sold 4 t-shirts and 3 large purses, and 9 small ones.

Her earning in the first week = 4 × $15 + 3 × $59 + 9 × $32 = $525

In the second week, she sold another 5 t-shirts, 7 large bags, and 4 small ones.

Her earning in the second week = 5 × $15 + 7 × $59 + 4 × $32 = $616

Last week she sold 8 t-Shirts and also sold 3 large purses and 5 small purses.

Her earning in the Last week = 8 × $15 + 3 × $59 + 5 × $32 = $457

The exact amount she made in 3 weeks = $525 + $616 + $457 = $1598

An explicit formula for the arithmetic sequence is aₙ = 10 - 20(n - 1).

Mathematically, the nth term of an arithmetic sequence can be calculated by using this mathematical expression:

aₙ = a₁ + (n - 1)d

Where:

From the information provided, we have the following parameters:

First term, a₁ = 10

Second term, a₂ = -10

Next, we would determine the common difference as follows:

Common difference, d = a₂ - a₁

Common difference, d = -10 - 10

Common difference, d = -20

Substituting the parameters into the mathematical expression, we have;

The total cost to rent 6 chairs and 5 tables is $49. This will be:

6c + 5t = 49

2c + 3t = 25

6c + 5t = 49

6 × (2c + 3t = 25)

2 × (6c + 5t = 49)

t = 6.5

Cost to rent table = $6.50

Since 2c + 3t = 25

2c + 3(6.5) = 25

2c + 19.5 = 25

The true solution for 2 ln e^ ln (5x) = 2 ln (15) is x = 3.

Given,

2 ln e^ ln (5x) = 2 ln (15)

Apply log rule;

logₐ (aᵇ) = b

ln (e^ln (5x)) = ln (5x)

2 ln (5x) = 2 ln (15)

Divide both sides by 2;

2 ln (5x) / 2 = 2 ln (15)/ 2

ln (5x) = ln (15)

For ln (5x) = ln (15), solve for 5x = 15;

That is,

5x = 15

Then,

x = 15/5

So,

x = 3

Check this by substituting it to 2 ln (5x) = 2 ln (15);

x = 3

2 ln (5 × 3) = 2 ln (15)

x = 3 makes this true.

2. Domain:  (-∞, ∞)

    Range:  [1, 5]

Step-by-step explanation:

Definitions

Note:  Assume that each square on the given graphs is 1 unit.

The domain of the function is restricted since the curve has two distince endpoints.  As each endpoint is marked by a closed circle, the x-value of the endpoints is included in the domain.

The function has a maximum point at (-1, 7) and a minimum point at (6, -3).

Therefore, the range of the function is restricted.

As there are arrows at both endpoints of the function, and the function is continuous between the arrowheads, the domain is unrestricted.

The maximum y-value is y = 5.  When x < 1, the line continues indefinitely at y = 5.

The minimum value is y = 1.  When x > 1, the line continues indefinitely at y = 1.

Therefore, the range of the function is restricted.

The coordinates of N are (5,-6)  so that segment MN is 3/7 of MP.

Given the coordinates of M is (-4,6) and the coordinates of P is (17,-22).

now we have to find the coordinates of N such that the MN : NP is 3:4 .

We will use the section formula:

The section formula states that:

[tex]{\displaystyle N=\left({\frac {mx_{2}+nx_{1}}{m+n}},{\frac {my_{2}+ny_{1}}{m+n}}\right)}[/tex]

Where the coordinates of the points are given and the ratio in which the points are divided is given.

Now we will substitute the values:

[tex]{\displaystyle N=\left({\frac {17\times 3+4\times -4}{3+4}},{\frac {3\times-22+4\times 6}{3+4}}\right)}[/tex]

Solving we get:

N=(5,-6)

The Section formula is used to determine the coordinates of things like the point that separates a line segment (internally or externally) into a particular ratio.

Both physics and mathematics regularly employ this formula. In mathematics, it is used to find the centroid and incenters of a triangle, but in physics, it is used to find the center of mass, equilibrium points, etc. The section formula is often used to find the midpoint of a line segment.

Therefore coordinates of N are (5,-6) so that MN is 3/7 of MP.
