TRUE or FALSE: In the quarter circle, the radius is 4 cm and the diameter is 8 cm.

viktelen [127]

Answer: False.

Step-by-step explanation:

There does not exist a "quarter circle" as a circle with a radius of 4 units, the only notable circle that does exist is the unit circle, that is the circle where the radius is equal to 1, represented by the equatin x^2 + y^2 = 1

The term "quarter circle" actually does refer to a fourth part of a circle, not to a circle of radius 4.

So the statement is false

What is the slope and equation of a line parallel to the y-axis passing through point (2,-5)

shepuryov [24]

Answer: $x=2$

Step-by-step explanation:

Given

Line passes through $(2,-5)$

and parallel to y-axis

If a line is parallel to another line then they must possess same slope

slope of y-axis is $\tan 90^{\circ}$

Now Equation of line is given by

$\Rightarrow \dfrac{y-(-5)}{x-2}=\tan 90^{\circ}$

we know $\tan 90 \rightarrow \infty$

$x-2$ must be zero for $\dfrac{y-(-5)}{x-2}\rightarrow \infty$

So, $x=2$ is the equation of required line

the ojos del salado volcano has an elevation about 3 times as great as the khangar volcano. If the khangar volcani is 6,562 feet

Vlada [557]

Answer:

The approximate elevation of the "ojos del salado" volcano is 19,686 feet above sea level

Step-by-step explanation:

Let

y -----> elevation of the "ojos del salado" volcano

x -----> elevation of the "khangar" volcano

we know that

The elevation of the "ojos del salado" volcano is about 3 times as great as the khangar volcano

$y=3x$ ----> equation A

we have

$x=6,562\ ft$

substitute the value of x in the equation A

$y=3(6,562)=19,686\ ft$

therefore

The approximate elevation of the "ojos del salado" volcano is 19,686 feet above sea level
