Michelle is debating between two different mortgages for $184,000. She found a 20-year fixed rate loan at 7.05% and 15-year fixed rate loan at the same rate. How much more interest will she pay for the 20-year loan versus the 15-year loan?
9514 1404 393
Answer:
$45,081
Step-by-step explanation:
The amortization formula can be used to find the monthly payment.
A = P(r/12)/(1 -(1 +r/12)^(-12t))
For the 20-year loan with r=0.0705 and P=184,000, the monthly payment is ...
A = $1432.08
The total amount repaid will be ...
12×20×1432.08 = 343,699.20
__
For the 15-year loan with the same parameters, the monthly payment is ...
A = 1658.99
and the total amount repaid is ...
12×15×1658.99 = 298,618.20
The difference in these repayment amounts is the difference in interest charges:
343,699.20 -298,618.20 = 45,081
The 20-year loan will cost $45,081 more than the 15-year loan.

if f(x) =3/4x+5/6 what is f(12)
Answer:
59/6
Step-by-step explanation:
Multiply 3/4 with 1212 x 3 will become 36 and divided by 4 is 99 + 5/6 cannot be added because they do not have the same denominator. Next you have to multiply 9/1 with 6/6 so that it has the same denominator as 5/6The problem will now become 5/6 + 54/6Now you can add the numerators and get the answerThe answer is59/6Which of the following is divisible by 5 but not 10 ? 230, 255, 260, 500

The population of Salisa is 12,500 and increases by 300 each month. The population of Corsair is 13,200 and increases by 200 each month. How many months will it take until the population of the two cities is the same?
It will take seven months for the population of each city to be the same.
On month seven, Salisa's population will be 14,600. (300x7=2,100+12,500=14600)
On month seven, Corsair's population will be 14,600 as well. (200x7=1,400+13,200=14600)
0=(2y−1)(8−y) Let y=u, y=d. What is the value of u×d
Answer:
The value of uxd=4
Step-by-step explanation:
since y=u, y=d, y=y
y=1/2 and 8
2y-1=0
2y=1
y=1/2
8-y=0
8=y
1/2*8=4
Answer:
4
Step-by-step explanation:
0=(2y−1)(8−y)
Using the zero product property
2y-1 =0 8-y =0
2y =1 8=y
y =1/2 y= 8
Let y=u, y=d
u = 1/2 d = 8
We want the value of u*d
u*d = 1/2 *8 = 4

What is the probability of rolling a 3? ASAP!!!!
Answer:
im sure its [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
hope it helps and Merry Christmas xx
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Proabability = favorable outcomes / total outcomes
A die has a total of 6 possible outcomes: 1 to 6
You want to roll a 3, so the number of favourable outcomes is 1.
[tex]\therefore[/tex] P(3) = [tex]\frac{1}{6}[/tex]

Which of the following DOES NOT equal 8%?
A.)0.08
B.)0.08
C.)8/100
D.)8.0%
E.)8.0%
F.)2/25
G.)4/5
Answer:
g
Step-by-step explanation:
8/100 is the same as 0.08 and 8,0% doesn't change and 2/25 is 8% as 1/25 is 4 so 2 would be 8 and it is g as 4/5 is 80%

A. f(x) = x + 14
B. f(x) = 12x + 16
C. f(x) = 12x + 14
D. f(x) = 14x + 12
The linear function f Eve can use to determine her pay would be; D. f(x) = 14x + 12
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is the form Ax + B = 0.
Given that Eve earns $14 per hour for yard work and an extra amount for dog walking on Saturdays.
The table shows the data;
Hours 1 2 3 4 5
Pay 26 40 54 68 82
Thus, the linear function f Eve can use to determine her pay is;
f(x) = 14x + 12
To check;
f(x) = 14x + 12
f(x) = 14(1) + 12
f(x) = 14 + 12 = 26

What is the inverse of the function f(x) = one-quarterx – 12? h(x) = 48x – 4 h(x) = 48x + 4 h(x) = 4x – 48 h(x) = 4x + 48
Answer:
The inverse of the function f(x) is h(x) = 4x + 48 ⇒ (D)
Step-by-step explanation:
To find the inverse of a function do these steps
Replace f(x) by ySwitch x and ySolve to find the new yReplace y by [tex]f^{-1}[/tex](x)Let us do these steps to solve the equation
∵ f(x) = [tex]\frac{1}{4}[/tex]x - 12
→ Replace f(x) by y
∴ y = [tex]\frac{1}{4}[/tex]x - 12
→ Switch x and y
∴ x = [tex]\frac{1}{4}[/tex]y - 12
→ Add 12 to both sides
∵ x + 12 = [tex]\frac{1}{4}[/tex]y - 12 + 12
∴ x + 12 = [tex]\frac{1}{4}[/tex]y
→ Multiply each term by 4
∵ 4(x) + 4(12) = 4([tex]\frac{1}{4}[/tex]y)
∴ 4x + 48 = y
→ Switch the two sides
∴ y = 4x + 48
→ Replace y by h(x)
∴ h(x) = 4x + 48
∴ The inverse of the function f(x) is h(x) = 4x + 48
Answer:
h(x) = 4x + 48 ⇒ (D)

2x ^3+ 3x^2+8x-4
to get 0 ?
Answer:
-2x^3 - 3x^2 -8x + 4 should be added
Step-by-step explanation:
Here, we want to know what should be added to the expression to get 0
What we should do in this case is to simply negate the values we have in the expression already
Adding the negated values will give 0
So, we have that;
-2x^3 - 3x^2 -8x + 4

X^3 = 1,000
algebratic equations
Answer:
10
Step-by-step explanation:
x³=1000
x=3√1000
x=10
Answer:
x = 10 or x = -5 + 5*i*sqrt(3) or x = -5 - 5*i*sqrt(3)
Step-by-step explanation:
x^3 = 1000
x^3 - 1000 = 0
(x - 10)(x^2 + 10x + 100) = 0
x = 10 or x^2 + 10x + 100 = 0
x = 10 or x^2 + 10x + 25 = -100 + 25
x = 10 or (x + 5)^2 = -75
x = 10 or x + 5 = sqrt(-75) or x + 5 = -sqrt(75)
x = 10 or x = -5 + 5*i*sqrt(3) or x = -5 - 5*i*sqrt(3)
An astronaut was exploring the moon of a distant planet, and found some glowing goo at the bottom of a very deep crater. She brought a 10-gram of the goo to her laboratory. She found that when the goo was exposed to light, the total amount of goo increased by 100% every hour. How much goo will she have sfter 1 hour?After 2 hours? After 3 hours? After n hours?
Answer:
20 ; 40 ; 80 ; 10(2^n)
Step-by-step explanation:
Given that:
Initial amount of goo (p) = 10 gram
Total amount of goo increased by 100% every hour ;
How much goo will she have sfter 1 hour?After 2 hours? After 3 hours? After n hours?
Using the relation :
Final amount = initial * (1 + rate)^t
Rate = 100% = 100/100 = 1
t = number of hours
Hence, after 1 hour :
Final amount = 10(1 + 1)^1
Final amount = 10(2)^1 = 20 grams
After 2 hours : t = 2
Final amount = 10(1 + 1)^2
Final amount = 10(2)^2 = 10 * 4 = 40 grams
After 3 hours ; t = 3
Final amount = 10(1 + 1)^3
Final amount = 10(2)^3 = 10 * 8 = 80 grams
After n hours ; t = n
Final amount = 10(1 + 1)^n
Final amount = 10(2)^n grams
To meet peak energy demand, an electric power cooperative buys back electricity generated locally. They pay #0.07 per solar-powered kWh (kilowatt-hour). How much money does a school make when it sells back 956 kWh to the cooperative?
Answer: #66.92
Step-by-step explanation:
Since the cooperative pays pay #0.07 per solar-powered kWh (kilowatt-hour), the amount that the school would make when it sells back 956 kWh to the cooperative would be calculated as:
= #0.07 × 956 kWh
= #66.92

a force of 12N acts for 5 s on a mass of 2 kg. What is the change in momentum of a mass of 10kg under the same condition
Answer:
The change in momentum is: 60 N.s
Step-by-step explanation:
By Newton's second law:
F = ∆p / ∆t
Given that
∆t = 5sF = 12NUsing the formula to determine the change in momentum
F = ∆p / ∆t
∆p = F × ∆t
= 12 × 5
= 60 N.s
Therefore, the change in momentum is: 60 N.s
