Allan purchased a zero coupon bond four years ago. He paid $3,000 and it has a face value of $3,500. How much money did he earn for holding the bond until maturity

Answers

Answer: $500

Explanation: The face value of any types of bond is the value of the bond at the time of maturity. So, the value of Allan's zero coupon bond is $3,500 because $3,500 is the face value of the bond he bought.

So the money he earns for holding the bond until maturity is the difference when the face value is subtracted to the cost he paid for the bond. Since

$3,500 - $3,000 = $500

Therefore, Allan earned $500 for holding the bond until maturity.

The length of a rectangle is 4 m longer than its width. if the perimeter of the rectangle is 36 m , find its area.

Answers

Answer:   The area of the rectangle is:  " 77 m² " .

__________________________________________________________
Note: The formula for the area, "A" of a rectangle:

→ A = L * w ;

in which:
A = "area (of rectangle)" ; [in units of "m² " ; that is: "square meters" ] ;

L = length = "(4 + w)" {in units of "meters (m)" } ;

w = width {in units of "meters (m)" } ;
_______________________________________________________

So; " A = L * w " ;

Substitute the known expression for the "length, L" ; & rewrite the formula for the given area of OUR area for the rectangle in OUR GIVEN PROBLEM:

  → A = (4 + w) * w '' ;
______________________________________________________

Note the formula for the perimeter, "P" ;

→ P = 2L + 2w ;

↔ 2L + 2w = P

→ 2L + 2w = 36 m ;
_____________________________________________________
We want to find the "area" , "A" :
_____________________________________________________
Using the formula for the "perimeter, "P" (of the rectangle) ; & given that the perimeter is: "36" (meters) ;

→ 2L + 2w = 36 ;

→ Let us plug in the values for "Length (L)" & "width (w)" ;

→ 2(w + 4) + 2w = 36 ;

So; (2*w) + (2*4) + 2w = 36 ; Solve for "w" ;

→ 2w + 8 + 2w = 36 ;

  → Combine the "like terms" :

+ 2w + 2w = 4w ;

→ And rewrite:

4w + 8 = 36 ;

Now, subtract "8" from EACH SIDE of the equation:

4w + 8 − 8 = 36 − 8 ;

to get:

4w = 28 ;

Now, divide EACH SIDE of the equation by "4" ;
to isolate "w" on EACH SIDE of the equation ; & to solve for "w" ;

4w / 4 = 28 / 4 ;

→ w = 7 ;   → The "width" of the rectangle is: " 7 m " .

Now, we can find the "length" of the rectangle:

The length, "L" , of the rectangle = 4 + w = 4 + 7 = 11 .

→ L = 11 . → The "length" of the rectangle is: " 11 m " .
___________________________________________________

Now, we can find the area, "A", of the rectangle.

A = L * w =  11 m * 7 m = " 77 m² " .

→ The area of the rectangle is: " 77 m² " .
__________________________________________________

To check our answer:
__________________________________________________

→ " P = 2L + 2w " ;

Given that "P = 36 m" ;

Plug in "36 m" (for "P") ; into the equation ;

and plug in our calculated values for
   "length, L" (which is "11 m") ; & "width, w" (which is "7 m") ;

to see if the equation holds true ; that is, to see if both sides of the equation are equal ;
_______________________________________________________

→ 36 m = ? 2L + 2w ?? ;

→ 36 m = ? 2(11 m) + 2(7 m) ?? ;

→ 36 m = ? 22 m + 14 m ?? ;

→ 36 m = ? 36 m ? Yes!
__________________________________________________

The process involves setting up an equation using the given perimeter and the relation between length and width, solving for width, then calculating length and subsequently the rectangle's area, resulting in 77 square meters.

The question involves finding the area of a rectangle given the relationship between its length and width, and its perimeter. First, let's represent the width as w meters. Therefore, the length will be w + 4 meters, since the length is 4 meters longer than the width. The perimeter of a rectangle is calculated as 2(length + width). Given the perimeter is 36 meters, we can set up the equation: 2(w + w + 4) = 36.

Simplifying this equation gives 2(2w + 4) = 36, and further simplification results in 4w + 8 = 36. Solving for w, we subtract 8 from both sides getting 4w = 28, and divide by 4 to find w = 7 meters. The length, being 4 meters longer, is 11 meters.

Finally, to find the area of the rectangle, we multiply the length by the width: Area = length × width = 11m × 7m = 77 square meters. Therefore, the area of the rectangle is 77 square meters.

Which of the following shows the graph of a line with a slope of 6/5 and a y intercept of -3?

Answers

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the slope of the line is 6/5 and y intercept is -3. It means the line must be passes through the point (0,-3).

The slope intercept form of a line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

Substitute m=6/5 and b=-3 in the above equation to find the equation of line.

[tex]y=\frac{6}{5}x+(-3)[/tex]

So, the equation of line is [tex]y=\frac{6}{5}x+(-3)[/tex].

Substitute y=0 in the above equation to find the x-intercept of the line.

[tex]0=\frac{6}{5}x-3[/tex]

Add 3 on both the sides.

[tex]0+3=\frac{6}{5}x-3+3[/tex]

[tex]3=\frac{6}{5}x[/tex]

Multiply both sides by 5.

[tex]15=6x[/tex]

Divide both sides by 6.

[tex]\frac{15}{6}=x[/tex]

[tex]2.5=x[/tex]

The x-intercept of the line is 2.5. It means the line must be passes through the point (2.5,0).

Since only in graph 1, the line passes through the points (0,-3) and (2.5,0), therefore the graph 1 represents the required line and option 1 is correct.

Answers

The frame will go around all 4 sides of the painting. That means that the length of each side of the painting will increase by 2.5 inches.

y-784=-1(x-30)^2
y=-1(x-30)^2+784
we know that
h=-b/2a
h=-60/(-2*1)
h=30
k=-30^2+60(30)-116
k=784

the vertex is at (30,784) this means that the point of symmetry of the parabola is at (30,784), in our context it means that the maximum number of windshields repaired is 30 and the minimum profit will be $784

Part B
x-intercept
to determine the x-intercept we let f(x)=0
thus
0=-2x^2+60x-116
solving for x we get:
x=2 and x=58
this means that when the shop repairs 2 windshields or 58 windshields, they will not make any profits

Quadrilateral ABCD is inscribed in this circle.

What is the measure of angle C?

Enter your answer in the box.

°

Answers

By the Inscribed Quadrilateral Theorem, a quadrilateral can only be inscribed if and only if opposite angles are supplementary. This means that [tex]\angle D \text{ and } \angle B[/tex] are supplementary, or add up to 180°. This gives us the equation
(3x + 9)° + (2x - 4)° = 180°
Combine like terms:
5x + 5 = 180
Subtract 5 from each side:
5x + 5 - 5 = 180 - 5
5x = 175
Divide both sides by 5:
5x/5 = 175/5
x = 35
This means that [tex]m \angle D=3(35)+9=114 \\m \angle B=2(35)-4 = 66 \\m \angle A=2(35) + 3=73[/tex]
We take these 3 angles away from 360 and we will have the measure of angle C:
360 - 114 - 66 - 73 = 107°
