As an incoming college freshman, Tina received a 10-year $9,900 Federal Direct

Unsubsidized Loan with an interest rate of 4.29%. She knows that she can begin making

loan payments 6 months after graduation but interest will accrue from the moment the funds

are credited to his account. How much interest will accrue while she is still in school and

over the 6-month grace period for this freshman year loan?

The **amount **charged on the loan which is the loan interest rate, increases as the **time **after the **initial** amount is credited into the account increases.

**Reasons**:

The **given **parameter are;

Loan amount, the principal, P = **$9,900**

Duration of the loan =** 10 years**

Loan interest rate, R = **4.29%**

**Required**:

The **amount **of **interest **that will **accrue **while she is **still **in **school **and over the 6-months grace period for the freshman loan.

**Solution**:

Based on a similar question on an online source, we have;

Interest, I = **P × R × T**

Where;

T = The time = **The time the freshman is in school + 6 months**

Therefore, normally, we have;

T = **4 years + 6 months **= 4.5 years

R = 4.29% = 0.0429

Therefore;

Interest, I = **9,900 × 0.0429 × 4.5** = 1911.195

The **interest **that will **accrue **while she is **still **in school and **over **the 6-months **grace period **for the loan,* I* = $1,911.195

Answer:

10. y degree = 102 degree

11. x degree = 103 degree

Step-by-step explanation:

The formula to calculate the sum of the interior range of polygons is (n-2) * 180.

With n being the number of sides.

From that sum, you can then deduce the angles of y or x, by substracting the other angles.

10. n = 4 => ( 4 - 2 ) * 180 = 2 * 180 = 360 degree

y = 360 - 120 - 85 - 53 = 102 degree

11. n = 5 => (5 - 2) * 180 = 3 * 180 = 540 degree

x = 540 - 117 - 100 - 105 - 115 = 103 degree

Serious help needed what is the domain and range

**Answer:**

**Step-by-step explanation:**

The arrows on the ends of the graph mean the graph extends indefinitely left and right. The **domain** is the horizontal extent of the graph, so it extends from -∞ to +∞, **all real numbers**.

__

The upward slant of the graph at the ends is ambiguous regarding the vertical extent of the graph. It could mean either of ...

the graph oscillates indefinitely between the values -1 and +5, orthe graph continues upward toward +∞We expect the latter case would be drawn with the ends of the arrows above the peak value shown. However, oscillation tends to involve a certain symmetry, and the graph has no symmetry about the local minimum points. In short the usual clues to the vertical extent are missing. Your guess is as good as mine.

**The range could be [-1, 5], or it could be [-1, ∞)**. We cannot tell from this graph.

_____

*Additional comment*

The shape of the graph does not seem to match that of a 4th-degree polynomial, so we're not at all certain what sort of function is being plotted here. (A 4th-degree polynomial gets steeper beyond the outside zeros, rather than flatter, as shown here.) A couple of different functions with the approximate characteristics shown are graphed in the attachment.

**Step-by-step explanation:**

Find the equation of the linear function represented by the table below in slope-intercept form.

**Answer:**

y = 2x - 5

**Step-by-step explanation:**

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (13, 21) ← 2 ordered pairs from the table

m = [tex]\frac{21-(-9)}{13-(-2)}[/tex] = [tex]\frac{21+9}{13+2}[/tex] = [tex]\frac{30}{15}[/tex] = 2 , then

y = 2x + c ← is the partial equation

To find c substitute any ordered pair from the table into the partial equation

Using (3, 1 )

1 = 6 + c ⇒ c = 1 - 6 = - 5

y = 2x - 5 ← equation of linear function

Three men can build a wall in 8 days. How long will it take them if they have the help of 2 boys? Assume that each boy works half as fast as each man.

(with explanation pls)

**Answer:**

6 days

**Step-by-step explanation:**

2 boys that each work half as fast as the men is equivalent to having one extra man. So instead of 3 men we have 4. 4/3 the manpower means 3/4 the time. 3/4 of 8 is 6.

**Answer:**

**6 days.**

**Step-by-step explanation:**

The 3 men can build 1/8 of a wall in 1 day.

So 1 man can build 1/24 wall in 1 day.

So 1 boy can build 1/48 in 1 day and 2 boys can build 1/24 wall in 1 day.

So we have the equivalent of 4 men working and they can build 4 * 1/24

= 1/6 of a wall per day

So the answer is 6 days.

-8y + 1 = -9y. solve for y.

Answer: y = -1

Step-by-step:

-8y + 1 = -9y

Subtract 1 from both sides

-8y = -9y-1

Add 9y to both sides to isolate y

y = -1

Step-by-step:

-8y + 1 = -9y

Subtract 1 from both sides

-8y = -9y-1

Add 9y to both sides to isolate y

y = -1

Simplifying

8y + -1 = 9y

Reorder the terms:

-1 + 8y = 9y

Solving

-1 + 8y = 9y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-9y' to each side of the equation.

-1 + 8y + -9y = 9y + -9y

Combine like terms: 8y + -9y = -1y

-1 + -1y = 9y + -9y

Combine like terms: 9y + -9y = 0

-1 + -1y = 0

Add '1' to each side of the equation.

-1 + 1 + -1y = 0 + 1

Combine like terms: -1 + 1 = 0

0 + -1y = 0 + 1

-1y = 0 + 1

Combine like terms: 0 + 1 = 1

-1y = 1

Divide each side by '-1'.

y = -1

Simplifying

y = -1

8y + -1 = 9y

Reorder the terms:

-1 + 8y = 9y

Solving

-1 + 8y = 9y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-9y' to each side of the equation.

-1 + 8y + -9y = 9y + -9y

Combine like terms: 8y + -9y = -1y

-1 + -1y = 9y + -9y

Combine like terms: 9y + -9y = 0

-1 + -1y = 0

Add '1' to each side of the equation.

-1 + 1 + -1y = 0 + 1

Combine like terms: -1 + 1 = 0

0 + -1y = 0 + 1

-1y = 0 + 1

Combine like terms: 0 + 1 = 1

-1y = 1

Divide each side by '-1'.

y = -1

Simplifying

y = -1

Use the following figure to answer BOTH parts the question

(a) Describe in words a sequence of transformations that maps ∆ to ∆′′′.

(b) Write an ordered-pair rule for each transformation in the sequence.

**Transformation **involves changing the position of a **shape**

(a) The sequence that maps both triangles

From the figure the **coordinates **of both **triangles **are:

[tex]A = (-5,0)[/tex]

[tex]B = (-2,1)[/tex]

[tex]C = (-4,2)[/tex]

[tex]A' = (4,-2)[/tex]

[tex]B' = (1,-1)[/tex]

[tex]C = (3,0)[/tex]

Start by **reflecting triangle **ABC across the **y-axis**.

The rule of this **transformation **is:

[tex](x,y) \to (-x,y)[/tex]

So, we have:

[tex]A = (5,0)[/tex]

[tex]B = (2,1)[/tex]

[tex]C = (4,2)[/tex]

Next, **translate **the **triangle **1 unit left and 2 units down

The rule of this **transformation **is:

[tex](x,y) \to (x,-1,y-2)[/tex]

So, we have:

[tex]A' = (4,-2)[/tex]

[tex]B' = (1,-1)[/tex]

[tex]C = (3,0)[/tex]

Hence, the **sequence **that **maps **∆ABC to ∆A′B′C′ is **reflection **across the **y-axis**, followed by **horizontal shift **to the **left **by 1 unit, and **vertical shift down **by 2 units

(b) The ordered pair rule

In (a), we have:

[tex](x,y) \to (-x,y)[/tex] ---- reflection

[tex](x,y) \to (x,-1,y-2)[/tex] --- translation

Combine both **transformations**, so we have the following **ordered pair**:

[tex](x,y) \to (-x,-1,y-2)[/tex]

Hence, the **ordered pair rule **is: [tex](x,y) \to (-x,-1,y-2)[/tex]

what is 0.04 km, 420 cm, 4,600 mm, and 4.3 meters in order from least to greatest

**Answer:**

420 cm, 4.3 meters, 4600 mm, 0.04 km

**Step-by-step explanation:**

We can solve this by converting each to the same unit. I will be using meters.

0.04 km

1 km = 1000 meters

1000 meters / 1 km = 1

multiply 0.04 km by 1 = 1000 meters / 1 km , keeping the km at the bottom to cross out

0.04 km * 1000 meters / 1 km = 40 meters

420 cm

100 cm = 1 meter

1 meter / 100 cm = 1

multiply 420 cm by this, keeping cm at the bottom so it crosses out

420 cm * 1 meter / 100 cm = 4.2 meters

4600 mm

1000 mm = 1 meter

1 meter / 1000 mm = 1

4600 mm * 1 meter / 1000 mm = 4.6 meters

Therefore, our order is

420 cm, 4.3 meters, 4600 mm, 0.04 km
