Let
A (-4,35)
B (-3,20)
C (-2,10)
D (-1,5)
E (0,8)
F (1,10)
G (2,15)
H (3,30)
I (4,48)

using a graph tool

case a) y=2.23x²+1.62x+5.26
see the attached figure N 1

case b) y=4.63x²+0.84x+4.14
see the attached figure N 2

case c) y=0.98x²+3.06x+6.02
see the attached figure N 3

case d) y=3.72x²+2.94x+3.21
see the attached figure N 4

using a <span>Quadratic Regression Calculator
</span>the <span>Best Fit Second-Degree Quadratic Regression is
2.228x</span>²+1.617x+5.255

Fatima saved $15,000 toward a down payment on a house. She makes $5,375 a month. What is the maximum loan she can take on a hous

Fittoniya [83]

We will use $\frac{28}{36}$ ratio to determine how much can Fatima afford as a loan for her house.

Let gross income of Fatima = $ x

Amount earned by Fatima monthly= $ 5,375

36 % of 5,375=

$\frac{36}{100}\times 5,375=1935$ $

Maximum amount that can be paid as a loan monthly = $ 1935

Total money that she can pay yearly for house loan if Fatima allowable money for paying loans is $ 1935=

$1935 \times 12=23220$ $

Money saved as a down payment = $ 15,000

So, maximum amount loan Fatima can take on a house= 23220 + 15000=$38,220

She is not allowed for loan for house if the cost of house is any of the four options.

(B) 28 % of $ 5375=

$\frac{28}{100}\times 5,375=1505$ $

Maximum amount that Fatima spend on her house monthly= $ 1505

Amount that fatima can spend yearly on her house = 1505× 12 =$18,060

For the four options given , none of the option matches Fatima's expectations.

4. A triangle has vertices A(4, 2), B(3, 7), and C(–4, –5).

Alex

To draw the median of the triangle from vertex A, the mid point of BC must be determined. The median of the vertex A is given at (-1/2, 1). See explanation below.

<h3>How you would draw the median of the triangle from vertex A?</h3>

Recall that B = (3, 7)

and C = (-4, -5).

Note that when you are given coordinates in the format above, B or C = (x, y)
Hence the mid point of line BC is point D₁ which is derived as:
D₁ $[ (\frac{3-4}{2})$ , $(\frac{7-5}{2}) ]$
hence, the Median of the Vertex A = (-1/2, 1).
