A family is purchasing a house and needs to finance a $195,000 mortgage from the bank with an annual percentage rate (apr) of 5.3%. the family is financing it over 30 years and making monthly payments. what is the monthly payment?
The monthly payment of the family is $1082.84.
Value of the mortgage P= $195,000
Annual Percentage Rate APR= 5.3%
Time n = 30 years = 360 months
What is the formula for monthly payment or EMI?Monthly Payment = [tex]\frac{Pr(1+r)^n}{(1+r)^n-1}[/tex]
Where P = Amount of Mortgage
r = monthly rate of interest
n = tenure in months.
Put P = $195,000
r = APR/12= 5.3%/12
n = 360
So, EMI = $1082.84
Therefore, The monthly payment of the family is $1082.84.

Step-by-step explanation:
what is 3c2+ 2c- 16?
factoring
In the given question, we have to factorise the equation:
3c² + 2c - 16Therefore, by using the middle term splitting method:
This method is used in equations which are in the form of ax² + bx + c. Here, we split the middle term into two terms which on multiplying gives ac and on adding or subtracting gives bx .➙ 3c² + 2c -16
➙ 3c² - 6c + 8c - 16
➙ ( 3c² - 6c )+ (8c - 16 )
➙ 3c( c - 2 ) + 8 ( c - 2 )
➙ ( c - 2 ) ( 3c + 8 )
Factorisation of a quadratic polynomial of the type ax² + bx + c where (a ≠ 1) .
To factorise ax² + bx + c, we have to find two numbers whose sum is equal to the coefficient of x and product is equal to the coefficient of x² and constant term.Consider the factorisation of 3c² + 2c – 16 .
We have to find two numbers whose sum is +2 and product (3 × 16) = 48 .
Obviously, the two numbers are 6 and 8 .
[tex]{ \qquad \sf { \dashrightarrow{ 3c {}^{2} + 2c - 16 }}}[/tex]
So, We can write it as,
[tex]{ \qquad \sf { \dashrightarrow{ 3c {}^{2} + 8c - 6c - 16 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ c (3c + 8) -2 (3c + 8) }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ ( c -2 )(3c + 8) }}}[/tex]
The town of Springfield had a population, P, of 100,000 in 2008. The population grew by 5% per year from 2008 to 2011. If x is the number of years since 2008, which expression describes this growth?
Answer:
100,000+.05^x=P
Step-by-step explanation:
The expression which best described the total population is P = 100000 × (1.05)ˣ; 1 ≤ x ≤ 3.
What is the pattern?A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.
The hint which is present in a given pattern hides in the pattern only.
Total population P in 2008 = 100000
Total population In 2009 = 100000 + 5% of 100000
⇒ 100000 + 0.05 × 100000
⇒ 1.05 × 100000
Total population P in 2010 ⇒
⇒ (1.05 × 100000) + 5% of (1.05 × 100000)
⇒ (1.05 × 100000) + 0.05 × 1.05 × 100000
⇒ 1.05 × 100000[ 1 + 0.05]
⇒ 1.05² × 100000
So it will follow this series.
Therefore,
1.05 × 100000, 1.05² × 100000, 1.05³ × 100000
The generalized term is ;
P = 100000 × (1.05)ˣ; 1 ≤ x ≤ 3
Hence "The expression which best described the total population is P = 100000 × (1.05)ˣ; 1 ≤ x ≤ 3".

My bowling average for four games was 160.
Two of my games were 155 and 169.
What was the average of my other two games?
Answer:
Step-by-step explanation:
The average of 4 games was 160. The average consists of the sum of all the scores, divided by 4:
(Sum of Games)/4
Sum of 2 games is (155 + 169) = 324
Lets let the sum of the two unknown games be x.
(234 + x)/4 = 160
(234 + x) = 640
x = 316
x consists of 2 games, so their average is (316/2) = 158 per game for the other 2 games.
===============
Check:
(155+169+158+158)/4
(640/4) = 160 average for all games.
If the base of a square building and an equilateral triangle building have the same perimeter,
how do the areas of their floors compare?
The relationship between the areas of the floors is [tex]A_s = \frac{3\sqrt 3}{4} A_t[/tex]
How to compare the areas?Let the side length of the base of the square building be l, and the side length of the base of the equilateral triangle building be s
So, the perimeter of both buildings is
P = 4l --- the squareP = 3s --- the equilateral triangleBoth perimeters are equal.
So, we have:
4l = 3s
Divide both sides by 4
[tex]l = \frac 34s[/tex]
Square both sides
[tex]l^2 = \frac{9}{16}s\²[/tex]
The area of an equilateral triangle is:
[tex]A_t = \frac{\sqrt 3}{4}s^2[/tex]
And the area of a square is
[tex]A_s = l^2[/tex]
Make s^2 the subject in [tex]A_t = \frac{\sqrt 3}{4}s^2[/tex]
[tex]s^2 = \frac{4A_t}{\sqrt 3}[/tex]
Substitute [tex]s^2 = \frac{4A_t}{\sqrt 3}[/tex] and [tex]A_s = l^2[/tex] in [tex]l^2 = \frac{9}{16}s\²[/tex]
[tex]A_s = \frac{9}{16} * \frac{4A_t}{\sqrt 3}[/tex]
Evaluate
[tex]A_s = \frac{9}{4} * \frac{A_t}{\sqrt 3}[/tex]
Rationalize
[tex]A_s = \frac{3\sqrt 3}{4} A_t[/tex]
Hence, the relationship between the areas of the floors is [tex]A_s = \frac{3\sqrt 3}{4} A_t[/tex]

let a and b be the roots of the equation x^2-2(p+1)x+p^2+8=0. If the absolute value of the difference of a and b equals to 2. find p
Answer:
4
Step-by-step explanation:
a and B are the roots of
[tex] {x}^{2} - 2(p + 1)x + {p}^{2} + 8 = 0[/tex]
[tex] {x}^{2} - 2px - 2x + {p}^{2} + 8 = 0[/tex]
This look like a parabola since p will be a constant so let use a quadratic formula
[tex] {x}^{2} -(2p + 2)x + {p}^{2} + 8 = 0[/tex]
[tex]2p + 2± \frac{ \sqrt{4 {p}^{2} + 8p + 4 - (4 {p}^{2} + 32) } }{2} [/tex]
[tex]2p + 2± \frac{ \sqrt{8p - 28} }{2} [/tex]
[tex]2p + 2± \frac{2 \sqrt{2p - 7} }{2} [/tex]
[tex]2p + 2± \sqrt{2p - 7} [/tex]
So the roots are
[tex]2p + 2 + \sqrt{2p - 7} [/tex]
and
[tex]2p + 2 - \sqrt{2p - 7} [/tex]
We know the distance between these two points are
2 so
[tex] |(2p + 2) + \sqrt{2p - 7} - (2p + 2) - \sqrt{2p - 7} | = 2[/tex]
[tex] | \sqrt{2p - 7} + \sqrt{2p - 7} | = 2[/tex]
[tex] |2 \sqrt{2p - 7} | = 2[/tex]
[tex]2 \sqrt{2p - 7} = 2[/tex]
[tex]p = 4[/tex]
Let plug it in to see.
[tex] {x }^{2} - 2(4 + 1)x + {4}^{2} + 8 = 0[/tex]
[tex] {x}^{2} - 10x + 24 = 0[/tex]
[tex](x - 6)(x - 4) = 0[/tex]
[tex]x = 4[/tex]
[tex]x = 6[/tex]
So they have a distance of 2.

Answer: 2.48
Step-by-step explanation:
We have the ad that shows:
6 lemons for .....................1.86 dollars
8 lemons..............................?
the cost for 8 lemons= (8*1.86)/6=2.48
of course we can use another method,
1.86/6=0.31 cents for 1 lemon
8*0.31=2.48 and we get the same answer
Answer:
$2.48
Step-by-step explanation:
1.86/6=0.31 which is the cost for 1 lemon. 0.31*8=2.48 which is for 8 lemons.

A computer's normal price is $1400. The shop is now offering $130 discount. How many percent is the discount
Answer:
9% discount (i think im not the best at percentages sorry)
Step-by-step explanation:
since we already know how much we are getting off of the original price, we dont have to subtract anything
so you would divide this price, 130, from 1400
130/1400= 0.0928
then you would have to muliply this number by 100
0.0928 x 100= 9.28

Graph the function f(x) = – 4(x + 4)2 square + 7.
Plot the vertex. Then plot another point on the parabola. If you make a mistake, you can erase your parabola by selecting the second point and placing it on top of the first.
Graph attached
Answer:
vertex = (-4, 7)
(-3, 3) and (-2, -9)
(-6, -9) and (-5, 3)
Step-by-step explanation:
Given function: [tex]f(x) = -4(x + 4)^2 + 7[/tex]
Vertex form of a quadratic function: [tex]f(x)=a(x-h)^2+k[/tex]
(where (h, k) is the vertex)
From inspection, we can see that the given function is in vertex form.
h = -4 and k = 7
Therefore, the vertex is at (-4, 7)
As [tex]a[/tex] is negative, the parabola will open downwards.
When graphing functions, it is useful to determine the axis intercepts.
The curve will intercept the y-axis when x = 0.
Substituting x = 0 into the function:
[tex]f(0) = -4(0 + 4)^2 + 7=-57[/tex]
Therefore, the y-intercept is at (0, -57)
**cannot plot this on the given graph area as it is out of range**
The curve will intercept the x-axis when y = 0.
Setting the function to 0 and solving for x:
[tex]-4(x + 4)^2 + 7=0[/tex]
[tex]\implies -4(x + 4)^2=-7[/tex]
[tex]\implies (x + 4)^2=\dfrac74[/tex]
[tex]\implies x+4=\pm\sqrt{\dfrac74}[/tex]
[tex]\implies x=-4\pm\dfrac{\sqrt{7}}{2}[/tex]
Therefore, the x-intercepts are at (-2.7, 0) and (-5.3, 0) to 1 dp.
Finally, input values of x either sides of the x-intercepts for further plot points:
(-3, 3) and (-2, -9)
(-6, -9) and (-5, 3)
