Answer:

The vertex is at (-8,-3)

Step-by-step explanation:

The function is of the form

y = a|x-h| + k where (h,k) is the vertex

f(x) = |x+ 8|– 3

f(x) = |x - - 8|– 3

The vertex is (-8,-3)

$\frac { 10 }{ 8 } =\frac { n }{ 10 } \\ \\ 10\cdot \frac { 10 }{ 8 } =\frac { n }{ 10 } \cdot 10\\ \\ \frac { 100 }{ 8 } =n$

$\\ \\ n=\frac { 4\cdot 25 }{ 4\cdot 2 } \\ \\ \therefore \quad n=\frac { 25 }{ 2 }$

Between which two ordered pairs does the graph of f(x) = one-halfx2 + x – 9 cross the negative x-axis?

Doss [256]

None of Option are correct

Step-by-step explanation:

The Given function is f(x) = y = $\frac{1}{2} x^{2} + x -9$

Here, f(x) is quadratic function and it asked that when function cross the Negative X-axis.

If any function cross the X-axis then, Point of intersection will have y component as zero.

Therefore, f(x) = y = $\frac{1}{2} x^{2} + x -9$

y = $\frac{1}{2} x^{2} + x -9 = 0$

Solving quadratric equation,

Comparing with $ax^{2} + bx + c= 0$

We get a= $\frac{1}{2}$ , b=1, c=(-9)

Since,

$x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}$

$x=\frac{- 1+\sqrt{(1)^{2}-4(\frac{1}{2})(-9) }}{2(\frac{1}{2})}$

$x=\frac{-1+\sqrt{1+(2)(9)}}{1}$

$x=\frac{-1+\sqrt{19}}{1}$

$x=-1+\sqrt{19}and x=-1-\sqrt{19}$

Thus, None of option are correct.

Verification.....

A) (–6, 0) and (–5, 0) give quadratic function : y = $x^{2} + 11x +30$

B) (–4, 0) and (–3, 0) give quadratic function : y = $x^{2} + 7x +12$

C) (–3, 0) and (–2, 0) give quadraric function : y = $x^{2} + 5x +6$

D) (–2, 0) and (–1, 0) give quadratic function : y = $x^{2} + 3x +2$

100 POINTS!!!! Answer to the picture below.

Art [367]

Answer:

A 23 of people who prefer plan 1 are from the 35-45 age group and 42% of people from the 46-55 age group prefer plan 2.

Step-by-step explanation:

add everyone who prefers plan 1 = 60

age 36-45 / total of plan 1 = 14/60 = .23 or 23%

add everyone in age group 46-55 = 50

in age group 46-55 and prefers plan 2 = 21 / 50 = 0.42 or 42%
