Find the quadratic function y=ax^2 + bx + c whose graph passes through the given points. (-3,37), (2,-8), (-1,13)

melamori03 [73]

The quadratic function is $y=1x^{2} + (-8)x + 4$

Step-by-step explanation:

The quadratic function given is $ax^{2} + bx + c=y$

and same quadratic function is passes through (-3,37), (2,-8), (-1,13)

Replacing points one by one

we get,

For (-3,37) :

$a(-3)^{2} + b(-3) + c=37$

$9a + -3b + c=37$ = equation 1

For (2,-8) :

$a(2)^{2} + b(2) + c=(-8)$

$4a + 2b + c=(-8)$ = equation 2

For (-1,13)

$a(-1)^{2} + b(-1) + c=(13)$

$a + -1b + c=13$ = equation 3

Solving the linear equation to get values of a,b,c

Subtract equation 2 with equation 3

we get, $(4a + 2b + c)-(a + -1b + c)=(-8)-13$

$(3a + 3b )=(-21)$

$(a + b )=(-7)$ = equation 4

Now, Subtract equation 1 with equation 2

we get, $(9a + -3b + c)-(4a + 2b + c)=(37)-(-8)$

$(5a - 5b )=(45)$

$(a - b )=(9)$ = equation 5

Now, Add equation 4 with equation 5

we get, $(a + b)+(a - b)=(-7)+(9)$

$(2a - 0b )=(2)$

$(a)=1$

Replacing value of a in equation 5

$(a - b )=(9)$

$(1 - b )=(9)$

$(b)=(-8)$

Replacing value of a and b in equation 1

$9a + -3b + c=37$

$9(1) + -3(-8) + c=37$

$9 + 24 + c=37$

$c=4$

Thus,

The quadratic function $y=1x^{2} + (-8)x + 4$

If point P partitions line BA, what would be the part to whole ratio?

sattari [20]

Answer:

The part AP to the whole AB ratio is 1:5

The part BP to the whole BA ratio is 4:5

Step-by-step explanation:

The given information are;

The number of parts in AB = 5 parts

The number of parts in AP = 1 part

The ratio of the part AP to the whole part AB is given as follows;

The ratio of AP to AP = The ratio of 1 part (AP) to 5 parts (AB)

Therefore;

The ratio of AP to AB = 1:5

The part AP to the whole AB ratio = 1:5, similarly, we have;

The ratio of BP to BA = The ratio of 5 part (BP) to 5 parts (BA)

Therefore;

The ratio of BP to BA = 4:5

The part BP to the whole BA ratio = 4:5.
