Answer:

<em>Answer is option d</em><em>)</em><em>Lines</em><em> </em><em>2</em><em> </em><em>and</em><em> </em><em>4</em><em> </em><em>are</em><em> </em><em>perpendicular</em><em>. </em>

Step-by-step explanation:

$line \: 2 : 4y = 3x - 4 \\ 3x - 4y - 4 = 0 \\ slope \: of \: line \: 2 = \frac{ - coefficient \: of \: x \: }{coefficient \: of \: y} \\ \: \: = \frac{ - 3}{ - 4} \\ \: \: = \frac{3}{4} \\ let \: m1 =\frac{3}{4} \\ line \: 4 : 4x + 3y = - 6 \\ 4x + 3y + 6 = 0 \\ slope \: of \: line \: 4 = \frac{ - coefficient \: of \: x \: }{coefficient \: of \: y} \\ \: \: = \frac{ - 4}{3} \\ let \: m2 = \frac{ - 4}{3} \\ m1 \times m2 = \frac{3}{4} \times \frac{ - 4}{3} \\ m1 \times m2 = - 1 \\ then \: lie \: 2 \: and \: line \: 4 \: are \: perpendicular.$

Suppose that a function f(x) is defined for all real values of x except at xequals=c. can anything be said about the existence

Margaret [11]

we are given that

f(x) is defined for all values of x except at x=c

Limit may or may not exist

case-1:

If there is hole at x=c , then limit exist

case-2:

If there is vertical asymptote at x=c , then limit does not exist

Examples:

case-1:

$\lim_{x \to c} \frac{x^2-cx}{(x-c)}$

We can simplify it

$\lim_{x \to c} \frac{x(x-c)}{(x-c)}$

$=\lim_{x \to c} x$

$=c$

so, we can see that limit exist and it's value defined

case-2:

$\lim_{x \to c} \frac{1}{(x-c)}$

Left limit is

$\lim_{x \to c-} \frac{1}{(x-c)}$

$=-\infty$

Right Limit is

$\lim_{x \to c+} \frac{1}{(x-c)}$

$=+\infty$

so, we can see that left limit is not equal to right limit

so, limit does not exist

a diamond ring was reduced from $799.99 to $499.99 find the percent decrease in the price round the answer to the nearest tenth

Ilia_Sergeevich [38]

Answer:

The price was reduced by about 53%

Step-by-step explanation:

Per cent of change = (amount of change) ÷ (original amount)

% change = (799.99 - 375.99)/799.99

= 424 / 799

= .5300

= 53 %

Look at the square pyramid shown below. Which of the equation best represents volume of this pyramid terms of H?

UkoKoshka [18]

Answer:

J. V = 12h cubic units

Step-by-step explanation:

Volume if a square pyramid = ⅓*a²*h

Where,

h = height = ?

a = edge = 6 in.

Plug in the values

Volume = ⅓*6²*h

V = ⅓*36*h

V = 12*h

V = 12h cubic units
