Miranda is renovating her home and needs a $32,000 loan to pay for the renovations. The bank offers her a 4.8% annual compound interest rate if she pays it off in 3 to 5 years. How much more would Miranda pay for the 5 year loan than the 3 year loan?
Answer:
$3072
Step-by-step explanation:
The compound interest formula for the amount paid on the loan P = P₀(1 + rt/100) where P₀ = loan amount = $32,000, r = rate = 4.8 % per annum and t = time
For the 3 year loan, t = 3, So,
P = P₀(1 + rt/100)
P = $32,000(1 + 4.8 × 3/100)
P = $32,000(1 + 14.4/100)
P = $32,000(1 + 0.144)
P = $32,000(1.144)
P = $36608
For the 5 year loan, t = 5, So,
P' = P₀(1 + rt/100)
P' = $32,000(1 + 4.8 × 5/100)
P' = $32,000(1 + 24/100)
P' = $32,000(1 + 0.24)
P' = $32,000(1.24)
P' = $39680
So, the amount more Miranda pay for the 5 year loan than the 3 year loan is P' - P = $39680 - $36608 = $3072
In 3 years Miranda would pay $36,832.72.
In 5 years Miranda would pay $40,453.53.

A tablet and a digital camcorder are both on sale for 30% off. The regular price of the tablet is $185. The regular price of the camcorder is $140. What is the sale price of the tablet.
Answer:
$98
Step-by-step explanation:
Tablet
Divide 185 by 10 to get 18.5, this is 10% of the price.
Since it is 30% off, it is 70% of the price.
Multiply 18.5 by 7 to get the sale price, $129.50
Camcorder

Answer:
2x - 7y = -34.
Step-by-step explanation:
As the line we want is perpendicular to y= -7/2 x + 9 it's slope will be
-1 /(-7/2) = 2/7.
Now we find the point of intersection ofn the 2 given lines:
x + y = 10
3x - 4y = -12
Multiply the first equation by -3:
-3x - 3y = -30
Now add this last equation to the second one:
-7y = -42
y = 6
Plug y = 6 into the first equation:
x + 6 = 10
x = 4.
So the point of intersection is (4, 6) and the equation we want passes through this, so using the point-slope form of straight line we have:
y - 6 = 2/7(x - 4)
7y - 42 = 2(x - 4)
7y - 42 = 2x - 8
2x - 7y = -42 + 8
2x - 7y = -34
Answer:
y=(2/7)x+(7/3)
Step-by-step explanation:
y=-7/2(x)+9
y=mx+c
Therefore, slope of line y is -7/2
Because line y perpendicular to the required line
Therefore, slope of the required line is 2/7
x+y=10 ........(1)
3x-4y = -12 ......(2)
(1) x 4:
4x+4y =40 ......(3)
(3) + (2)
4x+4y+3x-4y=28
x=4
by substituting x=4 into (1), we have
y=10-4=6
Therefore, the point that the line intersects is (4, 6)
let y=(2/7)x+c be the required equation
(4, 6):
6=(2/7)4+c
c=21/4
therefore, the required equation is y=(2/7)x+(7/3).

Leroy and his friends ate some birthday cake at his party. After the party 1/4
of the cake was left. Leroy's brother ate 2/3 of the left-over cake. How much
of the whole cake did his brother eat?
A: 1/6
B: 2/3
C: 5/6
D: 1/5
This question is an illustration of multiplication of fractions. The amount of eaten by Leroy's brother is [tex]\frac 16[/tex]
Given that:
[tex]L = \frac 14[/tex] ----- The left over
[tex]F = \frac 23[/tex] ----- The fraction eaten by Leroy's brother
The fraction of the whole cake (B) eaten by Leroy's brother is:
[tex]B = L \times F[/tex]
So, we have:
[tex]B = \frac 14 \times \frac 23[/tex]
Cancel out common terns
[tex]B = \frac 12 \times \frac 13[/tex]
[tex]B = \frac 16[/tex]
Hence, Leroy's brother ate [tex]\frac 16[/tex] of the whole cake

If C = q^2-2+q and D = 3q^2+2q, find an expression that equals 3C - 3D in standard form.
Please help ;-;
Answer:
- 9q² - 3q - 6
Step-by-step explanation:
3C - 3D
= 3(q² - 2 + q) - 3(3q² + 2q) ← distribute parenthesis
= 3q² - 6 + 3q - 9q² - 6q ← collect like terms
= - 9q² - 3q - 6
The required expression is - 9q² - 3q - 6 which equals 3C - 3D in standard form.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given in the question as follows:
3C - 3D ....(i)
We have to determine the resultant expression that could represent the standard form.
As per the question, we have the equations
C = q² - 2 + q and D = 3q² + 2q
Substitute these equations into the expression (i):
3(q² - 2 + q) - 3(3q² + 2q)
Apply the distributive property of multiplication,
3q² - 6 + 3q - 9q² - 6q
Combine the likewise terms in the above expression,
- 9q² - 3q - 6
Thus, the resultant expression is - 9q² - 3q - 6.

Someone help:
1 Asalesman leaves home at 0800 and travels for 13 hours at an average
speed of 60km/h. He then stops for 30 minutes. He continues for 2 more
hours at 50km/h and stops for 1 hour. He then returns home and arrives
home at 1600.
a) Show this in a travel graph.
b) Calculate his average speed for his return journey.
Answer:
a) Please find attached the required travel graph with times increasing from (0:00) of the day of travel to the following day
b) The average speed of return journey = 880 km/(15.5 h) ≈ 56.77 km/h
Step-by-step explanation:
The given information includes;
The time of departure of the salesman, t₁ = 0800
The duration of travel of the salesman = 13 hours
The average speed with which the salesman travels = 60 km/h
The time duration in which he stops = 30 minutes
The speed with which he continues = 50 km/h
The time duration he travels at 50 km/h = 2 hours
The time he arrives home after he turns, t₂ = 16:00
The appropriate graph is a distance time graph
So as to show the given information in a travel graph, we calculate the distances as follows;
Time [tex]{}[/tex] Location
08:00 [tex]{}[/tex] 0
08:00 + 13 = 21:00 [tex]{}[/tex] 13 × 60 = 780
21:00 + 0.30 = 21:30 [tex]{}[/tex] 780
21:30 + 2:00 = 23:30 [tex]{}[/tex] 780 + 50 × 2 = 880
23:30 + 1:00 = 0:30 (24: hours ) [tex]{}[/tex] 880
16:00 [tex]{}[/tex](40 hours from 0:00 the previous day)
Therefore, we have;
Location; 0, 780, 780, 880, 880, 0
Time; 08:00, 21:00, 21:30, 23:30, 24:30, 40:00
To show the distance traveled over the given time periods graphically, we let 00:30 = 24.30 and the arrival time (the next day) 16:00 = 40.00 hours after midnight (0:00) the previous day
Please find attached the required travel graph created with Microsoft Excel
b) The average speed of return journey = (Total distance of return journey)/(Total time)
The total distance going = 880 km
Therefore the return journey is also 880 km
∴ The total time taken on return journey Δt = (Time at arrival home) - (Time of start of return journey)
∴ Δt = 40 - 24.5 = 15.5
Δt = 15.5 hour
∴ The average speed of return journey = 880 km/(15.5 h) ≈ 56.77 km/h.

The focus of a parabola is (-4, -5), and its directrix is y = -1. What is the formula for the parabola in standard form.
Answer:
[tex](x - (-4))^2 = -8(y - (-3))[/tex]
[tex]Where\ p<0[/tex]
Step-by-step explanation:
From the question we are told that:
Parabola focus co-ordinates
[tex]F=(-4, -5)\\Directrix is y = -1[/tex]
Generally the equation for standard form of Parabola is mathematically given by
[tex](x - h)^2 = 4p(y - k)[/tex]
where p≠ 0
Generally the equation for Directrix of Parabola is mathematically given by
[tex]y=k-p\\y=-1[/tex]
Generally the equation for Focus of Parabola F is mathematically given by
[tex]F=(h, k + p).[/tex]
[tex]F=(-4, -5)[/tex]
Therefore
[tex]k-p=-1[/tex]
[tex]k=-1+p[/tex]
Given
[tex]k+p=-5[/tex]
[tex]-1+p+p=-5[/tex]
[tex]2p=-4[/tex]
[tex]p=-2[/tex]
Therefore
[tex]k-p=-1[/tex]
[tex]k-(-2)=-1[/tex]
[tex]k=-3[/tex]
Generally the equation for standard form of Parabola is mathematically given by
[tex](x - (-4))^2 = 4(-2)(y - (-3))[/tex]
[tex](x - (-4))^2 = -8(y - (-3))[/tex]
[tex]Where p<0[/tex]
