Answer 1

Answer: The final answer would be 3.5 inches tall or if you need fractions it would be 3 and 1/2. Here’s the explanation: the candle is originally eight inches tall and for every hour it burns it loses 3/4 of an inch which is .75. It will be burning till 11:00 at night which means it will be burning for six hours. All you need to do is multiply how much of the candle is burned every hour (.75) by how many hours. This will give you 4.5 inches burned by 11:00. But the question asked for how tall the candle will be, so you simply just subtract how much of the candle will have burned(4.5 inches) by the height (8 inches) and you get 3.5 inches.

A local orchestra is holding a charity concert concert at the community center. Each adult ticket $12, and child ticket costs $8. The organizers of the event hope to raise no less than $2,500, and the community center can seat up to 280 people. This graph and system in inequalities represent this situation, where x represents the number of adult tickets and y represents the number of child tickets. 12x + 8y> 2,500. X + y < 280

Answers

Rewrite the function by completing the square.
f(x) = x^2 – 10x—96

Answers

Answer:

$f(x) = (x - 5)^(2) - 121$ .

Step-by-step explanation:

The goal is to rewrite $f(x)$ in the vertex form $a\, (x - h)^(2) + k$ by completing the square (where $a$ , $h$ , and $k$ are constants.)

Expand the vertex form expression:

$\begin{aligned}& a\, (x - h)^(2) + k\n &= a\, (x - h)\, (x - h) + k \n &= a\, \left(x^2 - h\, x - h\, x + h^2\right) + k \n &= a\, \left(x^2 - 2\, h\, x + h^2\right) + k\n &= a\, x^2 - 2\, a\, h\, x + \left(a\, h^2 + k\right) \end{aligned}$ .

Compare this expression to $f(x) = x^2 - 10\, x - 96$ and solve for the constants $a$ , $h$ , and $k$ . Make sure that the coefficient of each term matches:

Coefficient for the $x^2$ term: $a$ in the expanded expression and $1$ in the expression for $f(x)$ . Hence, $a = 1$ .

Coefficient for the $x$ term: $(-2\, a\, h)$ in the expanded expression and $(-10)$ in the expression for $f(x)$ . Hence, $-2\, a\, h = -10$ .

Coefficient for the constant term: $\left(a\, h^2 + k\right)$ in the expanded expression and $(-96)$ in the expression for $f(x)$ . Hence, $a\, h^(2) + k = -96$ .

Substitute $a = 1$ into the second equation, $-2\, a\, h = -10$ , and solve for $h$ .

$-2 \, h = -10$ .

$h = 5$ .

Substitute both $a = 1$ and $h = 5$ into the third equation, $a\, h^(2) + k = -96$ , and solve for $k$ .

$5^2 + k = -96$ .

$k = -121$ .

Therefore, $a\, (x - h)^(2) + k$ becomes $(x - 5)^2 + (-121)$ .

Hence, the vertex form of the parabola $f(x)$ would be:

$f(x) = (x - 5)^(2) - 121$ .

Answer:

(x - 5)² -121 = 0

Step-by-step explanation:

if you need to find the roots you can take the square root of each side:

(x-5)² = 121

square root of (x-5)² is x-5

square root of 121 is ±11

first root: x-5 = 11

x = 16

second root: x-5 = -11

x = -6

Consider w1 = 4 + 2i and w2 = –1 – 3i. Which graph represents the sum w1 + w2?

Answers

Answer:

Option (2)

Step-by-step explanation:

Two points having real and imaginary parts are,

w₁ = 4 + 2i

w₂ = -1 - 3i

By adding these numbers,

w₁ + w₂ = (4 + 2i) + (-1 - 3i)

= (4 - 1) + (2 - 3)i

= 3 - (1)i

Since, coordinates of a number on the graph are (x, y)

Here x = Real part

y = Imaginary part

Therefore, sum of these numbers will be (3, -1).

Option (2) will be the correct graph.

The bar diagram represents the ratio of points scored by the home team and the visiting team in a basket ball game. How many points did the visiting team score if the home team scored 84 points?

Answers

Answer:

60 points.

Step-by-step explanation:

Bar diagram which represents the ratio of the points earned by the home team and visitor's team.

Fro the bar diagram,

Ratio of the points earned = $\frac{\text{Points earned by the home team}}{\text{Points earned by visitor's team}}$

= $(7)/(5)$

If the points earned by the home team = 84

$\frac{\text{Points earned by the home team}}{\text{Points earned by visitor's team}}$ = $(7)/(5)$

$\frac{84}{\text{Points earned by visitor's team}}$ = $(7)/(5)$

Points earned by the visitor's team = $(84* 5)/(7)$

= 60

Therefore, 60 points were earned by the visitor's team.

Which function is a quadratic function?P(x)=2x(×^2+6)+1
M(x)=-4(x+3)-2
t(x)=-8x^2(x^2-6+1
H(x)=3x(x-2)-4

Answers

The correct answer is: [D]: " H(x) = 3x(x - 2) - 4 " .
__________________________________________________
Note: A "quadratic function" takes the form of:
__________________________________________________
f(x) = ax² + bx + c ;
_________________________________________________
Answer choice: [D]: " H(x) = 3x(x - 2) - 4 " ;

takes this form:
_________________________________________________
" H(x) = 3x(x - 2) - 4 " ;

→ " 3x(x - 2) - 4 " ;

Note the "distributive property" of multiplication:
_________________________________________________

a(b + c) = ab + ac ; AND

a(b - c) = ab - ac ;
_________________________________________________

→ As such;

" 3x(x - 2) = (3x * x) - (3x * 2) = 3x² - 6x;

So, we can rewrite the expression:

→ " 3x(x - 2) - 4 " ;

as: → " 3x² - 6x - 4 ;

And the entire function as:

H(x) = 3x(x - 2) - 4 ;

as:

H(x) = 3x² - 6x - 4 ;

Which takes the form of a "quadratic function" ;

→ f(x) = ax² + bx + c ;

in which: a = 3 ; b = - 6 ; c = - 4 .
